Description

本発明は、電動車両や蓄電池に電力供給可能な充電手段を設けた電気機器、たとえば少なくとも一部が屋外に設置する照明機器、空調機器、給湯機器、または貯湯機器のような電気機器とその制御方法、プログラムに関するものである。   The present invention relates to an electric device provided with a charging means capable of supplying electric power to an electric vehicle or a storage battery, for example, an electric device such as a lighting device, an air conditioner, a hot water supply device, or a hot water storage device, at least a part of which is installed outdoors, and its control. It relates to methods and programs.

家庭を一例として説明する。家庭には電動車両として、すでに電動自転車が普及している。またこれから家庭で簡単に充電できる電気自動車やプラグイン自動車の普及が予見されている。   A home will be described as an example. Electric bicycles are already widely used in homes as electric vehicles. In addition, the spread of electric vehicles and plug-in vehicles that can be easily charged at home is foreseen.

これらは家庭の１００Ｖや２００Ｖの交流電源でバッテリーを充電するので駐輪場や駐車場に１００Ｖコンセントやそれを含めた充電装置があれば便利である。しかしながら既築の住宅の対応を含めてそのような環境をどの家庭でも用意できるわけではない。   Since these batteries are charged by a 100V or 200V AC power source at home, it is convenient if there is a 100V outlet or a charging device including the same in a bicycle parking lot or a parking lot. However, not all homes can provide such an environment, including support for existing houses.

電気自動車より先に普及した電動自転車の場合は、バッテリーを電動自転車本体から取り外して家庭に持ち帰って宅内のコンセントで充電するのが一般的である。自宅の自転車置き場にコンセントやバッテリーの充電装置（たとえば充電台）があればその場で充電でき、バッテリーの運搬が不要となる。   In the case of an electric bicycle that has become popular before an electric vehicle, it is common to remove the battery from the electric bicycle body, take it home, and charge it at an outlet in the home. If there is an outlet or a battery charger (for example, a charging stand) in the bicycle storage area at home, the battery can be charged on the spot, eliminating the need to carry the battery.

電気自動車の場合は、バッテリーが大きく重いので取り外して運搬するわけにはいかない。駐車場に充電用のコンセントを用意するか、自宅とは別のところ（充電スタンドなど）で充電することになる。   In the case of an electric vehicle, the battery is large and heavy, so it cannot be removed and transported. You will have to use a charging outlet in the parking lot or charge it at a location other than your home (such as a charging stand).

ところで、家庭で充電するときには電力使用料金の安くなる時間帯を意識して利用するとよい。たとえば２００Ｖ電源を扱うオール電化住宅では時間帯別料金制度があり、その電力使用料金は２３時〜午前７時の電力使用料金を１ｋＷあたりは９円程度、その前後の１７時〜２３時と午前７時〜１０時は２３円程度、午前１０時〜１７時は２８円〜３３円程度である。つまり２３時〜午前７時の一番安い電力使用料金は午前１０時〜１７時の電力使用料金の約１／３である。   By the way, when charging at home, it is better to use it while paying attention to the time zone when the electricity usage fee is cheap. For example, in an all-electric house that handles 200V power, there is a fee system according to the time zone, and the power usage fee is from 9 o'clock to 7 am, about 9 yen per kW, before and after 17:00 to 23:00 From 7:00 to 10:00, it is about 23 yen, and from 10:00 to 17:00, it is about 28 to 33 yen. That is, the cheapest electricity usage fee from 23:00 to 7:00 am is about 1/3 of the electricity usage fee from 10:00 to 17:00.

このことから、電気自動車用の駐車場を備えた新築の住宅では、電力使用料金の安くなる時間帯に通電するようタイマー時計を備えた充電用のコンセントを駐車場付近に設けたものがある。   For this reason, some newly built houses equipped with a parking lot for electric vehicles have a charging outlet provided with a timer clock in the vicinity of the parking lot so as to be energized in a time zone when the electricity usage fee is reduced.

駐車場に設置するコンセントと充電装置の一例として特許文献１がある。これは充電中に他人が操作しないよう施錠式の充電ボックス１２０としたもので、図２２のように駐車場に面した建物壁に備えている。充電装置の操作部、接続部を施錠式の充電ボックス１２０内にしたので就寝中や留守中に第三者が勝手に操作・接続して盗電するのを防ぐことができる。   There exists patent document 1 as an example of the electrical outlet installed in a parking lot, and a charging device. This is a lockable charging box 120 to prevent others from operating during charging, and is provided on the building wall facing the parking lot as shown in FIG. Since the operation unit and the connection unit of the charging apparatus are provided in the lockable charging box 120, it is possible to prevent a third party from operating and connecting without permission while sleeping or absent.

また特許文献２（図２３）のように、電力使用料金が安くなる時間帯に電気自動車１０８を充電するときに、同時に電気温水器１０５や電子レンジ１０９などの家庭電化機器を使用して、その結果、住宅で契約している許容電流（契約電力容量）を超えたときにアンペアブレーカー（電流制限器）１０４が遮断することがある。   Further, as in Patent Document 2 (FIG. 23), when the electric vehicle 108 is charged at a time when the electricity usage fee is reduced, the household electric appliances such as the electric water heater 105 and the microwave oven 109 are simultaneously used. As a result, the ampere breaker (current limiter) 104 may be cut off when the allowable current contracted in the house (contract power capacity) is exceeded.

これを防ぐために、家庭全体の使用電流（使用電力）を配電盤１０３で監視してアンペ
アブレーカー１０４の遮断前に家庭電池システム１０７や電気自動車１０８の充電の電流（電力）を減らし電子レンジ１０９や照明１１０の使用を優先するものがある。 In order to prevent this, the current (electric power used) of the entire home is monitored by the switchboard 103, and the electric current (electric power) for charging the household battery system 107 and the electric vehicle 108 is reduced before the ampere breaker 104 is cut off. Some prioritize the use of 110.

特許文献１のような充電装置は、これから設計・新築する住宅であれば電気自動車を意図してこのような適所に充電のための交流電源コンセントを設置することが可能である。 A charging device like patent document 1 can install the alternating current power outlet for charge in such a suitable place with the intention of an electric vehicle if it is a house designed and built from now on .

その他の方法として、家屋内の分電盤から駐車場に配線して屋外に充電コンセントを設けることである。   Another method is to wire the parking board from the distribution board in the house to the parking lot and provide a charging outlet outdoors.

ここで、電気自動車の充電には電動自転車に比べて容量の大きな蓄電池を短時間で充電させるため最大で１０数Ａの電流を流す。一般家庭の分岐ブレーカーの許容電流は１５Ａまたは２０Ａなので、電気自動車の充電と同時に、同じ分岐ブレーカーに接続された他の電気機器で電力を使用すると許容電流を超えて分岐ブレーカーが遮断することがある。   Here, when charging an electric vehicle, a current of a maximum of several tens A is passed in order to charge a storage battery having a larger capacity than an electric bicycle in a short time. Since the allowable current of a branch breaker in a general household is 15A or 20A, when the electric vehicle is charged, if the electric power is used by another electric device connected to the same branch breaker, the branch breaker may be cut off exceeding the allowable current. .

既存の分岐ブレーカーを既存の電気機器と電気自動車とで共有すると、充電と他の電気機器との同時使用でブレーカーが遮断する恐れがある。空っぽの蓄電池をフル充電するには１００Ｖ電源で約７時間、２００Ｖ電源で約４時間の時間とすれば、４〜７時間のあいだ同じ分岐ブレーカーの電気機器を使用するときは気をつける必要がある。   If an existing branch breaker is shared between an existing electric device and an electric vehicle, the breaker may be blocked due to simultaneous use of charging and other electric devices. To fully charge an empty storage battery, it takes about 7 hours with a 100V power source and about 4 hours with a 200V power source. When using the same branch breaker electrical equipment for 4 to 7 hours, care must be taken. is there.

そのため、電気自動車の分岐ブレーカーは、他の機器との併用ではなく専用のブレーカーとすることが望ましい。つまり、分電盤に電気自動車専用の分岐ブレーカーを設けアンペアブレーカーから分電し、それを屋外に設置する充電コンセントまで配線工事する。また、駐車場付近に屋外コンセントの操作手段（通電オン／オフ、通電タイマー）を設ける。   Therefore, it is desirable that the branch breaker of the electric vehicle is a dedicated breaker rather than being used in combination with other devices. In other words, a branch breaker dedicated to electric vehicles is installed on the distribution board, and electricity is distributed from the ampere breaker, and then wiring is performed to a charging outlet installed outdoors. Also, an outdoor outlet operation means (energization on / off, energization timer) is provided near the parking lot.

こうなると電気工事はそれなりの手間と費用がかかり、電気自動車を購入すれば誰でも簡単に自宅で充電できる、というわけにはいかない。   If this happens, electrical work will take some time and money, and if you buy an electric car, anyone can easily charge it at home.

また、電力使用料金が安くなる時間帯に電気自動車や電動自転車を充電すると特許文献２に記載のとおり他の家庭電化機器の動作や運転と重なり、住宅で契約している許容電流（契約電力容量）を超えてアンペアブレーカー（電流制限器）が遮断することがある。   Moreover, if an electric vehicle or an electric bicycle is charged during a time period when the power usage fee is reduced, as described in Patent Document 2, it overlaps with the operation and operation of other home appliances, and the allowable current contracted in the house (contracted power capacity) ) May break the ampere breaker (current limiter).

特に充電時間が深夜であれば、アンペアブレーカーが遮断すると夜中に照明が使えずトイレに困る、早朝に炊きあげるようタイマー予約していた炊飯器が動作せず朝食が食べれない、また電気自動車で出勤・外出しようとしても充電されていない、という事態が予想される。   Especially if the charging time is late at night, if the ampere breaker shuts off, the lighting will not be used during the night and the toilet will be in trouble, the rice cooker that has been reserved for the timer to work early in the morning will not work and you will not be able to eat breakfast, and you will also work on an electric car・ It is expected that they will not be charged when going out.

つまり、電気自動車の充電により家庭で同時使用する電力が増えるとなれば、今までの電力会社との契約電力容量では足りなくなり電力容量を増やす場合が多くなる。たとえばオール電化住宅では６ｋＶＡ（１００Ｖで６０Ａ相当）を超えると基本料金が毎月数百円が増える。   In other words, if the electric power used simultaneously at home increases due to the charging of the electric vehicle, the contracted power capacity with the power company so far becomes insufficient and the power capacity increases in many cases. For example, in an all-electric home, the basic charge will increase by several hundred yen every month if it exceeds 6kVA (equivalent to 60A at 100V).

これを回避する一つの方法として、特許文献２のように電流制限を行うものがある。この方法は分電盤のアンペアブレーカーに流れる電流を検知して充電コンセントの制御を行うため、やはり配電盤と電気自動車の充電コンセントとのあいだで配線工事が必要になる。   One method for avoiding this is to limit the current as in Patent Document 2. Since this method detects the current flowing through the ampere breaker of the distribution board and controls the charging outlet, wiring work is also required between the distribution board and the charging outlet of the electric vehicle.

以上のように、電気自動車の魅力の一つにガソリンに比較して単位走行距離のコストが安いということがある。しかしながら、そのための充電設備に必要な費用が大きいと電気自動車の普及の妨げとなりかねない。   As described above, one of the attractions of electric cars is that the cost of unit mileage is lower than that of gasoline. However, if the cost required for the charging equipment is large, it may hinder the spread of electric vehicles.

また、特許文献２では深夜に電気自動車を充電する場合を検討しており、家庭電化機器を使用してアンペアブレーカーが遮断する前に電気自動車の充電で使用する電力を減らすものである。家庭電化機器や電気自動車の使い方、時間帯別電力使用料金を考慮して電力制限の対象を異ならせることが望ましい。たとえば、電気自動車の充電状態に応じて電気自動車の充電を優先させるなどである。   Patent Document 2 examines the case where an electric vehicle is charged at midnight, and uses electric appliances to reduce the electric power used for charging the electric vehicle before the ampere breaker shuts off. It is desirable to vary the power restriction target in consideration of usage of home appliances and electric vehicles, and power usage fees by time of day. For example, priority is given to charging of an electric vehicle according to the state of charge of the electric vehicle.

上記は家庭で説明したがこれに限らず、商店や事務所、工場、施設などにおいても駐輪場や駐車場で電動車両を充電する場合に共通した事項である。また、電気自動車や電動自転車に限らず、ある場所に蓄電池を新たに設置して、それを充電する充電手段が必要となったときにもやはり同じことが起きる。   Although the above is explained at home, the present invention is not limited to this, and is common to charging electric vehicles at bicycle parking lots and parking lots in shops, offices, factories, and facilities. The same thing happens when a storage battery is newly installed in a certain place and a charging means for charging it is required, not limited to an electric vehicle or an electric bicycle.

本発明は、以上の従来の課題を解決するもので、充電手段が必要となった場所に、大がかりな電気工事を必要とせずに誰でも簡単に充電コンセントを設けることを目的としている。またそのための電気工事の費用や契約電力容量に関わる使用電気料金の基本料金のアップを抑えることを目的としている。   An object of the present invention is to solve the above-described conventional problems, and it is an object of the present invention to easily provide a charging outlet in a place where a charging means is required without requiring a large-scale electrical work. In addition, the purpose is to suppress the increase in the basic charge of the electricity charge used for the cost of electric construction and contracted power capacity.

前記従来の課題を解決するために、本発明の充電手段付き電気機器は、交流電源に接続して蓄電池に電力供給可能な充電手段を備え、蓄電池の充電状態に応じて充電手段に供給する電力を制御する電力供給制御手段を備える。そして、電力供給制御手段は、蓄電池の充電状態を検知して定電流充電モードで充電するときは、電気機器の使用電力よりも充電手段による電力供給を優先し、蓄電池の充電状態を検知して定電流充電モード以外で充電するときは、充電手段による電力供給よりも電気機器の使用電力を優先する。 In order to solve the conventional problems, charging means with electrical equipment of the present invention is connected to an AC power source comprises a charging means capable of supplying power to the storage battery, and supplies to the charging means in accordance with the state of charge of the power storage pond Power supply control means for controlling power is provided. And when the power supply control means detects the state of charge of the storage battery and charges it in the constant current charging mode, the power supply control means gives priority to the power supply by the charging means over the power used by the electrical equipment, and detects the state of charge of the storage battery. When charging in a mode other than the constant current charging mode, priority is given to the power used by the electric device over the power supply by the charging means.

本発明は、たとえば照明機器、空調機器、給湯機器、または貯湯機器のような電気機器に充電手段を設けるので、この充電手段付き電気機器を予め設置しておけば後に電気自動車や電動自転車を購入したときに、この充電手段付き電気機器に電気自動車や電動自転車などを接続すれば大がかりな電気工事を必要とせずに駐車場、駐輪場で充電することができる。 In the present invention, charging means is provided in an electric device such as a lighting device , an air conditioner, a hot water supply device, or a hot water storage device. Therefore, if the electric device with the charging means is installed in advance, an electric vehicle or an electric bicycle can be purchased later. When an electric vehicle or an electric bicycle is connected to the electric device with the charging means, it can be charged in a parking lot or a bicycle parking lot without requiring a large-scale electric work.

このときに、蓄電池の充電状態に応じて充電手段に供給する電力を制御するので、電気機器本体の動作よりも充電のほうを優先する等の制御が可能となる。そして、大電力を必要とする定電流充電モードで充電するときは電気機器の使用電力よりも充電手段による電力供給を優先することで充電残量が少なくなった蓄電池の充電をスムーズに行わせることができる。 This and come, and controls the power supplied to the charging unit according to the state of charge of the battery, it is possible to control such as giving priority to more charge than the operation of the electric apparatus unit. And when charging in the constant current charging mode that requires a large amount of power, priority should be given to the power supply by the charging means over the power used by the electrical equipment, so that the storage battery with a low remaining charge can be charged smoothly. Can do.

第１の発明は、交流電源に接続して蓄電池に電力供給可能な充電手段を備え、蓄電池の充電状態に応じて充電手段に供給する電力を制御する電力供給制御手段を備える充電手段付き電気機器である。そして、電力供給制御手段は、蓄電池の充電状態を検知して定電流充電モードで充電するときは、電気機器の使用電力よりも充電手段による電力供給を優先し、蓄電池の充電状態を検知して定電流充電モード以外で充電するときは、充電手段による電力供給よりも電気機器の使用電力を優先する。 A first aspect of the present invention is connected to an AC power supply comprising a charging means capable of supplying power to the storage battery, the charging unit with electric with a power supply control unit for controlling electric power supplied to the charging means in accordance with the state of charge of the power storage pond Equipment. And when the power supply control means detects the state of charge of the storage battery and charges it in the constant current charging mode, the power supply control means gives priority to the power supply by the charging means over the power used by the electrical equipment, and detects the state of charge of the storage battery. When charging in a mode other than the constant current charging mode, priority is given to the power used by the electric device over the power supply by the charging means.

これにより、電気機器に充電手段を設けるので、この充電手段付き電気機器を予め設置しておけば後に電気自動車や電動自転車を購入したときに、この電気機器の充電手段に電気自動車や電動自転車などを接続すれば大がかりな電気工事を必要とせずに駐車場、駐輪場で充電することができる。   As a result, since the electric device is provided with charging means, if the electric device with charging means is installed in advance, when the electric vehicle or electric bicycle is purchased later, the electric vehicle or electric bicycle is used as the charging means for the electric device. Can be charged at parking lots and bicycle parking lots without requiring extensive electrical work.

また、蓄電池の充電状態に応じて充電手段に供給する電力を制御するので、電気機器本体の動作よりも充電のほうを優先する等の制御が可能となる。そして、大電力を必要とする定電流充電モードで充電するときは電気機器の使用電力よりも充電手段による電力供給を優先することで充電残量が少なくなった蓄電池の充電をスムーズに行わせることができ
る。 Further, since the controlling electric power supplied to the charging means according to the state of charge of the battery, it is possible to control such as giving priority to more charge than the operation of the electrical machine body. And when charging in the constant current charging mode that requires a large amount of power, priority should be given to the power supply by the charging means over the power used by the electrical equipment, so that the storage battery with a low remaining charge can be charged smoothly. Can
The

第２の発明は、第１の発明において、電力供給制御手段は、蓄電池の充電状態を検知して定電流充電モードで充電するときは、交流電源の時間帯別電力使用料金情報によって電力使用料金が安くなる時間帯を選択して充電手段から電力を供給する充電手段付き電気機器である。 In a second aspect based on the first aspect, when the power supply control means detects the state of charge of the storage battery and charges the battery in the constant current charging mode, the power usage fee is determined according to the power usage fee information for each time zone of the AC power source. It is an electric device with a charging means that selects the time zone when the price is reduced and supplies power from the charging means.

これにより、充電のうちで大きな電力を必要とする定電流充電モードにかかる電力使用料金を下げることができる。   Thereby, the electric power usage fee concerning the constant current charge mode which requires big electric power among charge can be lowered | hung.

第３の発明は、交流電源に接続して、電動車両に搭載する蓄電池に電力供給可能な第一の充電手段と、電動車両とは別の蓄電池に電力供給する第二の充電手段と、蓄電池の充電状態に応じて第一、第二の充電手段に供給する電力を制御する電力供給制御手段と、蓄電池に充電した電力を電動車両に電力供給する手段とを備えた充電手段付き電気機器である。そして、電力供給制御手段は、第一、第二の充電手段に接続された蓄電池の一方が定電流充電モードであれば、定電流充電モードの蓄電池を定電圧充電モードまたはパルス充電モードの蓄電池よりも優先して電力供給する。 A third invention is connected to an AC power source, a first charging means capable of supplying power to the storage battery to be mounted in an electric vehicle, a second charging Hand stage power supplied to another storage battery and an electric vehicle, first, depending on the state of charge of the power storage pond, and the power supply control means for controlling the power supplied to the second charging means, the charging means with electricity and means to power the electric power charged in the storage battery to the electric vehicle Equipment. And if one of the storage batteries connected to the first and second charging means is in the constant current charging mode, the power supply control means can replace the storage battery in the constant current charging mode with the storage battery in the constant voltage charging mode or pulse charging mode. Also prioritize power supply.

これにより、蓄電池の充電状態に応じて第二の充電手段で交流電源から蓄電池に電力供給して充電し、第一の充電手段で蓄電池から電動車両に電力供給して充電する。 Thus , according to the state of charge of the storage battery, the second charging means supplies power from the AC power source to the storage battery, and the first charging means supplies power from the storage battery to the electric vehicle for charging.

そして、充電に大きな電力を必要とする定電流充電モードの蓄電池の充電を優先する。 Then, priority is given to charging of constant current charging mode of the battery that requires a large electric power to the charging.

第４の発明は、第３の発明において、電力供給制御手段は、交流電源の時間帯別電力使用料金情報によって電力使用料金が安くなる時間帯において、第一、第二の充電手段に接続された蓄電池がともに定電流充電モードであれば、第一の充電手段を第二の充電手段よりも優先して電力供給する。 In a fourth aspect based on the third aspect , the power supply control means is connected to the first and second charging means in a time zone in which the power usage fee is reduced by the power usage fee information by time zone of the AC power supply. If both of the storage batteries are in the constant current charging mode, the first charging means supplies power with priority over the second charging means.

これによって、電力使用料金が安くなる時間帯において、二つの蓄電池がともに定電流充電モードであれば電動車両の蓄電池に電力供給する第一の充電手段を優先して電動車両の充電にかかる電力使用料金を下げることができる。   As a result, when the two storage batteries are both in the constant current charging mode during the time period when the power usage fee is reduced, the first charging means that supplies power to the storage battery of the electric vehicle is given priority to use the electric power for charging the electric vehicle. The price can be reduced.

第５の発明は、第１〜４のいずれか１つの発明において、充電手段付き電気機器は交流電源とは別に小規模発電装置に接続して電源を得て、時間帯別電力使用料金情報においてその小規模発電装置が発電している時間帯は電力使用料金が安くなる時間帯と同じ扱いとする。 A fifth invention is the invention according to any one of the first to fourth inventions, wherein the electric device with a charging means is connected to a small-scale power generator separately from the AC power source to obtain a power source, The time period during which the small-scale power generator is generating power is treated the same as the time period during which the electricity usage fee is reduced.

以下、本発明の実施の形態について、図面を参照しながら説明する。なお、この実施の形態によって本発明が限定されるものではない。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

（実施の形態１）
図１は本発明の実施の形態１において、一般住宅における住宅建物１と電気自動車２、充電手段付き電気機器５を示す概観図である。 (Embodiment 1)
FIG. 1 is a schematic diagram showing a residential building 1, an electric vehicle 2, and an electric device 5 with a charging means in a general house in Embodiment 1 of the present invention.

なお、実施の形態は家庭で説明するがこれに限らず、商店や事務所、工場、施設などにおいても駐輪場や駐車場で電動車両を充電する場合でもよい。商用施設や公共施設であれば充電手段付き電気機器は家庭電化機器に限らず、利用者認識装置や自動精算機、自動販売機など屋外に設置される電気機器であればよい。   In addition, although embodiment demonstrates at home, it is not restricted to this, You may charge an electric vehicle in a bicycle parking lot or a parking lot also in a shop, an office, a factory, a facility, etc. If it is a commercial facility or a public facility, the electric device with a charging means is not limited to a home appliance, but may be an electric device installed outdoors such as a user recognition device, an automatic payment machine, or a vending machine.

電気自動車２には、蓄電池及びその蓄電池を充電するための車載充電回路３を載せている。使用者は電気自動車２の充電プラグ４をコンセント８に挿入して得た電力を車載充電回路で電流・電圧制御して蓄電池に充電する。   The electric vehicle 2 includes a storage battery and an in-vehicle charging circuit 3 for charging the storage battery. The user charges the storage battery by controlling the current and voltage of the electric power obtained by inserting the charging plug 4 of the electric vehicle 2 into the outlet 8 with an in-vehicle charging circuit.

充電プラグ４を挿入して充電するための充電手段付き電気機器として、住宅建物の庭や車庫に機器の一部が設置されるような電気機器を想定し、エアコンの室外機５ａや電気給湯機器の室外機や貯湯タンク５ｂ、車庫等の照明機器５ｃを例示する。これらには充電用のコンセント８が備えられており、このコンセント８に充電プラグ４を挿入することで簡単に電気自動車２が充電可能となる。なお、車載充電回路３の一部を電気機器５側に備える構成でも構わない。   As an electric device with a charging means for charging by inserting the charging plug 4, an electric device in which a part of the device is installed in a garden or garage of a residential building is assumed, and an outdoor unit 5a of an air conditioner or an electric hot water supply device is assumed. Illuminating equipment 5c such as an outdoor unit, a hot water storage tank 5b, and a garage is illustrated. These are provided with a charging outlet 8, and the electric vehicle 2 can be easily charged by inserting the charging plug 4 into the outlet 8. In addition, the structure provided with a part of vehicle-mounted charging circuit 3 in the electric equipment 5 side may be sufficient.

このように、屋外に設置される電気機器に充電手段を設けるので、この充電手段付き電気機器を予め設置しておけば後に電気自動車や電動自転車を購入したときに、この電気機器の充電手段に電気自動車や電動自転車などに接続すれば大がかりな電気工事を必要とせずに駐車場、駐輪場で充電することができる。   As described above, since the charging means is provided in the electric device installed outdoors, if the electric device with the charging means is installed in advance, when the electric vehicle or the electric bicycle is purchased later, the charging device of the electric device is used. If it is connected to an electric car or electric bicycle, it can be charged at parking lots and bicycle parking lots without requiring extensive electrical work.

また、充電手段付き電気機器は照明機器、空調機器、給湯機器、貯湯機器に限らず少なくとも電気機器本体機能の一部が屋外に設置される電気機器であればよい。電気自動車の充電プラグを屋外の電気機器に接続するので、電源コンセントとプラグとを中継する延長ケーブルを屋内から屋外に通しておく必要がなく防犯上好ましい。   Further, the electric device with a charging means is not limited to the lighting device, the air conditioning device, the hot water supply device, and the hot water storage device, and may be an electric device in which at least a part of the electric device main body function is installed outdoors. Since the charging plug of the electric vehicle is connected to an outdoor electric device, an extension cable that relays the power outlet and the plug does not need to be passed from the indoor to the outdoor, which is preferable for crime prevention.

次に、本発明の実施の形態１の充電手段付き電気機器とその周辺を示すブロック構成図を図２に示す。図１と同じ機能には同じ番号を付与する。   Next, FIG. 2 shows a block configuration diagram showing the electric device with charging means and its periphery according to the first embodiment of the present invention. The same functions as those in FIG. 1 are given the same numbers.

交流電源１１（家庭用１００Ｖまたは２００Ｖ電源）の上流にアンペアブレーカー１２が設置され、背景技術の特許文献２と同様に、家庭全体の使用電力が契約電力容量を超えるときにこれを遮断する。また、交流電源１１から電気機器５に給電するときはアンペアブレーカー１２との間に分岐ブレーカー１３（たとえば２０Ａの許容電流）を設置し、電気機器の異常動作や短絡により過電流が流れないようにする。他の電気機器１４とその分岐ブレーカー１５も同様である。   An ampere breaker 12 is installed upstream of the AC power supply 11 (household 100V or 200V power supply), and this is cut off when the power used in the entire home exceeds the contracted power capacity, as in Patent Document 2 of the background art. Further, when power is supplied from the AC power supply 11 to the electric device 5, a branch breaker 13 (for example, an allowable current of 20A) is installed between the ampere breaker 12 and an overcurrent does not flow due to an abnormal operation or short circuit of the electric device. To do. The same applies to the other electric devices 14 and their branch breakers 15.

本実施の形態１の電気機器５は充電手段・充電状態検知手段１６を屋外部２７に備え、これを用いて電気自動車２や電動自転車のような蓄電池３を搭載した電動車両を屋外で充電することができる。接続手段８は充電プラグとコンセントであり、電動車両以外の蓄電池に接続して充電してもよい（接続手段はプラグとコンセントに限らない）。   The electric device 5 according to the first embodiment includes a charging unit / charging state detection unit 16 in the outdoor unit 27, and uses this to charge an electric vehicle equipped with a storage battery 3 such as an electric vehicle 2 or an electric bicycle outdoors. be able to. The connecting means 8 is a charging plug and an outlet, and may be charged by connecting to a storage battery other than the electric vehicle (the connecting means is not limited to the plug and the outlet).

充電手段付き電気機器５の詳細な構成について以下に説明する。   The detailed configuration of the electric device 5 with charging means will be described below.

総使用電力検知手段１７は、充電手段１６への供給電力を含めた電気機器５全体での総使用電力を検知する電力計である。なお、総使用電力検知手段１７は電気機器５と別筐体にして、検知した総使用電力の情報を電気機器５と通信するコンセント形状のアダプタとしてもよい。   The total used power detecting means 17 is a wattmeter that detects the total used power in the entire electric device 5 including the power supplied to the charging means 16. The total power consumption detection means 17 may be a separate housing from the electric device 5 and may be an outlet-shaped adapter that communicates information on the detected total power consumption with the electric device 5.

電気機器５が所有する機器本来の機能は、電気機器の機能ブロック１８と、その機能ブロックとを制御する制御手段１９とで表す。たとえば、機能ブロック１８はコンプレッサ
ーやインバータ回路などのアクチュエータであり、エアコンであればエアコン機能、電気給湯機器であれば給湯機器能、貯湯機器であれば貯湯機能、照明機器であれば照明機能である。制御手段１９はそれらの機能を制御するマイコンとその周辺部である。 The original function of the device owned by the electric device 5 is represented by a functional block 18 of the electric device and a control means 19 for controlling the functional block. For example, the function block 18 is an actuator such as a compressor or an inverter circuit, and is an air conditioner function for an air conditioner, a hot water supply function for an electric hot water supply device, a hot water storage function for a hot water storage device, and an illumination function for a lighting device. . The control means 19 is a microcomputer for controlling these functions and its peripheral part.

また、電気機器本来の機能で使用する電力を検知するため、電気機器の使用電力検知手段２０を機能ブロック１８と制御手段１９の電源ラインに挿入する。   In addition, in order to detect the electric power used in the original function of the electric device, the electric power used power detecting means 20 of the electric device is inserted into the power line of the function block 18 and the control means 19.

電気機器の使用電力例を図３に示す。エアコンや電気給湯機器は最大で１０００〜２０００Ｗの電力を使用する。   An example of electric power used by an electric device is shown in FIG. Air conditioners and electric water heaters use a maximum of 1000 to 2000 W of power.

そして、電気機器５が備える充電機能として、接続手段８に接続された電気自動車２の蓄電池３を充電する充電手段１６と、それを制御する制御手段２１を備える。充電手段１６には、蓄電池３の状態に応じて充電に最適な電圧・電流を作り出す電圧・電流変換機能のほかに、蓄電池３の充電状態を検知する充電状態検知手段を備える。蓄電池の充電状態とそれに応じた充電の電圧・電流については後述する。   And as a charging function with which the electric equipment 5 is provided, the charging means 16 which charges the storage battery 3 of the electric vehicle 2 connected to the connection means 8, and the control means 21 which controls it are provided. The charging unit 16 includes a charging state detection unit that detects a charging state of the storage battery 3 in addition to a voltage / current conversion function that generates a voltage / current optimum for charging according to the state of the storage battery 3. The state of charge of the storage battery and the charging voltage / current corresponding thereto will be described later.

また、充電機能で使用する電力を検知するため充電手段の使用電力検知手段２２を充電手段１６と制御手段２１の電源ラインに挿入する。   In addition, the power consumption detecting means 22 of the charging means is inserted into the power supply lines of the charging means 16 and the control means 21 in order to detect the power used in the charging function.

たとえば、１６ｋＷｈの電気自動車の蓄電池を充電するのに家庭の２００Ｖ−１５Ａ電源で８時間程度かかる。すなわち、電気機器５の機能ブロック１８、１９と充電手段１６、２１とを併用して運転すると最大で４０００〜５０００Ｗの電力を使用することになり、このときは分岐ブレーカー１３が遮断する。   For example, it takes about 8 hours with a household 200V-15A power source to charge a storage battery of a 16 kWh electric vehicle. In other words, when the functional blocks 18 and 19 of the electric device 5 and the charging means 16 and 21 are operated in combination, a maximum power of 4000 to 5000 W is used, and at this time, the branch breaker 13 is cut off.

そこで分岐ブレーカー１３の遮断を防ぐために、電気機器が有する本来の機能で使用する電力と、充電機能で使用する電力を把握し、また、そのときの電力使用料金に応じて両機能を同時に運転させたり、両機能で使用する電力を割り当てて調整したり、いずれか一方を先に運転させるなど優先的に運転させる制御を行う電力供給制御手段２３を電気機器５は備えている。   Therefore, in order to prevent the breaker 13 from being interrupted, the power used by the original function of the electrical equipment and the power used by the charging function are grasped, and both functions are operated simultaneously according to the power usage fee at that time. The electric device 5 includes power supply control means 23 that performs control to preferentially operate such as allocating and adjusting power to be used in both functions, or operating either one first.

この電力供給制御手段２３は、優先的に運転させる電気機器の機能、充電機能について優先順位を記憶する優先順位記憶手段２４と、交流電源１１の時間帯別電力使用料金情報を記憶する電力使用料金情報記憶手段２５と、電気機器の使用電力と充電手段の使用電力の総和が所定値（交流電源１１からの供給能力）以下を維持するように電気機器５の動作を制御し充電手段１６から蓄電池に供給する電力を制御する使用電力演算手段２８とを備えている。   The power supply control means 23 includes a priority order storage means 24 for storing priorities for the functions and charging functions of the electrical equipment to be operated preferentially, and a power usage charge for storing power usage charge information for each time zone of the AC power supply 11. The operation of the electric device 5 is controlled so that the sum of the electric power used by the information storage means 25 and the electric device and the electric power used by the charging means is kept below a predetermined value (supplying capacity from the AC power supply 11). Power consumption calculating means 28 for controlling the power supplied to the power supply.

優先順位記憶手段２４は、後述するように電気機器の使用電力と蓄電池の充電状態と時間帯別電力使用料金情報に応じた優先順位を記憶している。また、使用者の使い勝手の良い優先順位を設定したり、優先順位記憶手段２４が電気機器と蓄電池の使用状況に応じて学習する構成でも構わない。   As will be described later, the priority order storage unit 24 stores priorities according to the power usage of the electric equipment, the state of charge of the storage battery, and the power usage fee information for each time zone. In addition, a user-friendly priority order may be set, or the priority order storage unit 24 may learn according to the usage status of the electric device and the storage battery.

電力使用料金情報記憶手段２５は、時間帯別電力使用料金の情報を予め記憶しておいたり、電力需要に応じて変化する時間帯別電力使用料金を通信ネットワーク経由で（図示しない）ダウンロードする構成のほか、後述するように太陽光発電や燃料電池から電力を発生するときに電力使用料金を異ならせることも考えられる。２００Ｖ電源を扱うオール電化住宅では時間帯別料金制度の電力使用料金情報を図４に示す。   The power usage fee information storage means 25 stores information on power usage fees by time zone in advance, or downloads power usage fees by time zone that changes according to power demand (not shown) via a communication network. In addition, as described later, it is conceivable to change the power usage fee when generating power from solar power generation or a fuel cell. FIG. 4 shows power usage fee information of the hourly rate system in an all-electric home that handles a 200V power source.

使用電力演算手段２８は、電気機器の使用電力検知手段２０によって電気機器の機能ブロック１８の使用電力値を、充電手段の使用電力検知手段２２によって充電手段１６から
蓄電池３への供給電力値を取得して、電気機器の使用電力と充電手段の使用電力との総和を演算する。あるいは、総使用電力検知手段１７で計測した電流値を電気機器の使用電力と充電手段の使用電力の総和として用いてもよい。 The used power calculation means 28 acquires the used power value of the functional block 18 of the electric device by the used power detection means 20 of the electric device, and the supplied power value from the charging means 16 to the storage battery 3 by the used power detection means 22 of the charging means. Then, the sum of the electric power used by the electric device and the electric power used by the charging means is calculated. Alternatively, the current value measured by the total power consumption detection unit 17 may be used as the sum of the power consumption of the electric device and the power consumption of the charging unit.

以上のように、使用電力演算手段２８は充電を含めた電気機器５全体の使用電力を得て、その総和が所定値以下になるよう電力供給の制御を行う。   As described above, the power consumption calculation means 28 obtains power consumption of the entire electric device 5 including charging, and controls power supply so that the total sum becomes a predetermined value or less.

（イ）電気機器の使用電力と充電手段の使用電力を検知して、所定値に対して電力の余裕が大きいときは電気機器５と充電手段１６とを同時に運転させる。   (A) The electric power used by the electric device and the electric power used by the charging means are detected, and the electric device 5 and the charging means 16 are operated simultaneously when there is a large margin of electric power with respect to the predetermined value.

（ロ）電気機器の使用電力と充電手段の使用電力を検知して、所定値に対して電力の余裕が少ないときは、電気機器５と充電手段１６との両方で使用する電力を割り当て調整して同時に運転させる。   (B) When the electric power used by the electric device and the electric power used by the charging means are detected and there is little power margin with respect to the predetermined value, the electric power used by both the electric device 5 and the charging means 16 is allocated and adjusted. Drive at the same time.

たとえば、電気機器が電気給湯機器であれば、お湯の沸き上げモードから保温モードに切り替えて使用電力を一時的に減らすことができる。電気機器がエアコンであれば運転モードや設定温度、風量を落として使用電力を一時的に減らすことができる。蓄電池では供給する電力（電流や電圧）を減らすことができる。   For example, if the electric device is an electric hot water supply device, the power consumption can be temporarily reduced by switching from the hot water boiling mode to the heat retaining mode. If the electrical device is an air conditioner, the operating mode, set temperature, and air volume can be reduced to temporarily reduce the power consumption. In the storage battery, the power (current and voltage) supplied can be reduced.

たとえば、図５（ａ）のように、時間ｔ１において電気機器の使用電力を減らしてから蓄電池の充電を行う。   For example, as shown in FIG. 5 (a), the storage battery is charged after reducing the power used by the electrical device at time t1.

（ハ）さらに所定値に対して余裕がないときは、電気機器５と充電手段１６とを同時に運転させずに、時間をずらして運転させる。   (C) Further, when there is no allowance for the predetermined value, the electric device 5 and the charging means 16 are operated at different times without being operated at the same time.

たとえば、電気機器５を先に運転し、電気給湯機器であれば、お湯の沸き上げモードで給湯完了した後、運転完了してから蓄電池の充電を開始する。エアコンであれば、運転開始時の急速モードで空間をある程度冷暖房した後、運転停止してから蓄電池の充電を開始する。   For example, if the electric device 5 is operated first and is an electric hot water supply device, after completing the hot water supply in the hot water boiling mode, charging of the storage battery is started after the operation is completed. If it is an air conditioner, after heating and cooling the space to some extent in the rapid mode at the start of operation, charging of the storage battery is started after the operation is stopped.

たとえば、図５（ｂ）のように、先に電気機器の運転を行い、時間ｔ２において電気機器の運転を終了してから蓄電池の充電を行う。   For example, as shown in FIG. 5B, the electric device is operated first, and the storage battery is charged after the operation of the electric device is finished at time t2.

なお、使用電力の総和の上限である所定値は分岐ブレーカー１３の許容電流とほぼ同じかそれ以下（または少し多め）を初期設定する。   The predetermined value, which is the upper limit of the total power used, is initially set to be approximately equal to or less than the allowable current of the branch breaker 13 (or slightly more).

また、使用者指示手段２６は電気機器５の運転状態を遠隔で表示し制御するリモコンで、電気機器の制御手段１９、充電手段の制御手段２１、電力供給制御手段２３の設定状態や運転状態を表示し、使用者が電気機器５の運転と蓄電池３の充電とを設定・制御することができる。   The user instruction means 26 is a remote controller that remotely displays and controls the operation state of the electric device 5. The user instruction means 26 indicates the setting state and operation state of the electric device control means 19, the charging means control means 21, and the power supply control means 23. The user can set and control the operation of the electric device 5 and the charging of the storage battery 3.

電気機器５と使用者指示手段２６との通信媒体は赤外線通信や無線通信（電波）、有線通信、電灯線通信などが考えられ、給湯機器のリモコンのように台所の壁に固定設置する形態や、エアコンのリモコンのように使用者が持ち運んで好みの場所で使用する。   The communication medium between the electric device 5 and the user instruction means 26 may be infrared communication, wireless communication (radio wave), wired communication, power line communication, and the like. Carry it like a remote control for an air conditioner and use it at your favorite place.

ここで充電状態検知手段１６による蓄電池の充電状態とそれに応じた充電の電圧・電流制御について図６を用いて説明する。図６はリチウム電池の場合の充電シーケンスを示したもので、横軸に充電時間、縦軸に右側目盛りは電圧を、左側目盛りを充電電流と充電容量を描く。単位として、１Ｃとは公称容量値の容量を有するセルを定電流放電して、ちょうど１時間で放電終了となる電流値である。   Here, the state of charge of the storage battery by the state of charge detection means 16 and the voltage / current control of charging corresponding thereto will be described with reference to FIG. FIG. 6 shows a charging sequence in the case of a lithium battery. The horizontal axis represents charging time, the vertical scale represents voltage, and the left scale represents charging current and charging capacity. As a unit, 1C is a current value at which discharge of a cell having a capacity of a nominal capacity value is constant-current discharged and the discharge is completed in exactly one hour.

図６に示すように、充電状態が０（グラフの左側）に近い状態から充電を開始すると最初は一定電流（１Ｃ電流）で充電を行う（定電流充電モード）。このとき電圧は充電にともなって上昇し、充電容量は時間にほぼ比例して充電される。   As shown in FIG. 6, when charging starts from a state where the charging state is close to 0 (left side of the graph), charging is initially performed with a constant current (1C current) (constant current charging mode). At this time, the voltage rises with charging, and the charging capacity is charged in proportion to the time.

そして、図６では充電容量が７５％（０．７５ＣＡｈ）以上のときは一定電圧（１Ｃ電圧）＝４．２Ｖで充電を行う（定電圧充電モード）。このとき電流は充電にともなって減少し、充電容量は時間を徐々に満充電（１．０ＣＡｈ）になる。   In FIG. 6, when the charging capacity is 75% (0.75 CAh) or more, charging is performed at a constant voltage (1C voltage) = 4.2 V (constant voltage charging mode). At this time, the current decreases with charge, and the charge capacity gradually reaches full charge (1.0 CAh) over time.

すなわち、定電流充電モードでは充電に大きな電力を必要とし、定電圧充電モードに移ると充電電力は小さくなっていく。   That is, in the constant current charging mode, a large amount of power is required for charging, and the charging power is reduced when the mode is changed to the constant voltage charging mode.

なお、定電圧充電モードは図６のように電圧を一定にしながら電流を減らしていくので時間がかかる。そこで、その代わりにパルス充電モードという方法がある。これは充電中の短時間だけ４．２Ｖを超えて電流を大きくして充電し、その後に電圧を見て４．２Ｖ以上であれば充電を停止、４．２Ｖ未満であれば再び４．２Ｖのパルスで電圧を行う。   The constant voltage charging mode takes time because the current is reduced while keeping the voltage constant as shown in FIG. Therefore, there is a method called a pulse charge mode instead. This is because charging is performed by increasing the current exceeding 4.2V for a short time during charging, and then stops charging if the voltage is 4.2V or more, and if it is less than 4.2V, it is 4.2V again. Voltage is applied with the pulse of.

以上のように、充電状態を検知しそれに応じて充電の電圧・電流の制御を行う。   As described above, the state of charge is detected, and charging voltage / current is controlled accordingly.

本実施の形態はこれを図２の充電手段・充電状態検知手段１６で行う例で説明するが、電気自動車３側の電力入力手段３で制御を行う構成も可能である。電力入力手段３、充電手段・充電状態検知手段１６、充電手段の制御手段２１は接続手段８を介して接続され、その構成は電気機器５側と電気自動車２側とに分けて分担するものである。ここでは図２を一例として説明する。   In the present embodiment, this is described with an example in which this is performed by the charging unit / charged state detecting unit 16 in FIG. 2, but a configuration in which control is performed by the power input unit 3 on the electric vehicle 3 side is also possible. The power input means 3, the charging means / charge state detecting means 16, and the charging means control means 21 are connected via the connecting means 8, and the configuration is divided between the electric device 5 side and the electric vehicle 2 side. is there. Here, FIG. 2 will be described as an example.

以上の構成において、本実施の形態１の充電付き電気機器の動作について図７のフローチャートを示して説明する。   With the above configuration, the operation of the electric device with charging according to the first embodiment will be described with reference to the flowchart of FIG.

最初のステップＳ１において、電気機器の使用電力検知手段２０によって電気機器の使用電力を検知し、充電状態検知手段１６によって蓄電池の接続の有無と接続時の充電状態を検知し、電力使用料金情報記憶手段２５から現在を含めて充電する時刻における電気料金情報を取得し、使用者指示手段２６から使用者の指示内容を取得する。使用者の指示がない場合もある。   In the first step S1, the power usage of the electrical device is detected by the power usage detection means 20 of the electrical device, the presence / absence of connection of the storage battery and the state of charge at the time of connection are detected by the charge state detection means 16, and the power usage fee information is stored. Electricity rate information at the time of charging including the present is acquired from the means 25, and the user's instruction content is acquired from the user instruction means 26. There may be no instruction from the user.

次にＳ２において、優先順位記憶手段２４から電気機器５の運転と電気自動車の蓄電池３の充電の優先順位を取得し、Ｓ１で取得した電気機器の使用電力と蓄電池の充電状態と電力使用料金情報から優先順位を判断する。そして、その判断に基づいて電力供給制御手段２３が電気機器の制御手段１９と充電手段の制御手段２１との電力供給制御を決定する。   Next, in S2, the priority order of the operation of the electric equipment 5 and the charging of the storage battery 3 of the electric vehicle is acquired from the priority order storage means 24, and the electric power usage, the charging state of the storage battery, and the electric power usage fee information acquired in S1. Judge the priority from Based on the determination, the power supply control means 23 determines the power supply control between the control means 19 of the electrical equipment and the control means 21 of the charging means.

優先順位について一例を図８に示す。左から、電気機器５の使用電力、蓄電池３の充電状態、電力使用料金情報の３つを入力とし、電力供給制御（ａ）〜（ｉ）を出力する。   An example of the priority order is shown in FIG. From the left, the power consumption control (a) to (i) are output with the power used by the electrical equipment 5, the state of charge of the storage battery 3, and the power usage fee information as inputs.

電力供給制御（ａ）〜（ｄ）は電気機器５が動作していて使用電力が大きいときで、このときの充電状態が定電流充電モード（図６で充電容量が７５％以下）であるときには充電でも大きな使用電力を必要とする場合である。   The power supply controls (a) to (d) are when the electric device 5 is operating and the power consumption is large, and the charging state at this time is the constant current charging mode (the charging capacity is 75% or less in FIG. 6). This is a case where a large amount of power is required even for charging.

ここで、電力使用料金情報を参照して電力使用料金の安い時間帯であるときは（ａ）のように蓄電池３の充電を優先することで、電力使用料金が安いときに蓄電池３に充電可能なときは充電し、可能であれば電気機器５も動作を継続する。   Here, referring to the power usage fee information, when the power usage fee is low, it is possible to charge the storage battery 3 when the power usage fee is low by giving priority to the charging of the storage battery 3 as shown in (a). When it is not charged, the electric device 5 continues to operate if possible.

また、電力使用料金の安くない時間帯であるときは（ｂ）のように電気機器５を優先することで、主な生活時間帯は電気機器５の使用を優先し、夜間に蓄電池５を充電できるよう充電せずに充電容量をそのまま空けておく。   In addition, when it is a time zone where the electricity usage fee is not cheap, priority is given to the electric device 5 as shown in (b), so that the use of the electric device 5 is prioritized during the main life time and the storage battery 5 is charged at night. Leave the charging capacity as it is without charging.

また、電気機器５が動作していて使用電力が大きいときで、このときの充電状態が定電圧充電モードまたはパルス充電モード（図３で充電容量が７５％以上）であるときには充電で必要とする電力が小さい場合である。   Further, when the electric device 5 is operating and the power consumption is large and the charging state at this time is the constant voltage charging mode or the pulse charging mode (the charging capacity is 75% or more in FIG. 3), charging is necessary. This is when the power is small.

ここでは（ｃ）、（ｄ）のように電力使用料金情報に関わらず電気機器を優先し、可能であれば充電手段１６で必要電力の小さい充電を行う。   Here, as in (c) and (d), priority is given to the electric equipment regardless of the power usage fee information, and charging is performed with a small amount of necessary power by the charging means 16 if possible.

一方、電力供給制御（ｅ）〜（ｈ）は電気機器５が動作していない、または動作していても使用電力が小さいときである。このときは電力使用料金情報を参照して電力使用料金の安い時間帯であるときは（ｅ）や（ｇ）のように蓄電池３の充電を優先することで、電力使用料金が安いときに蓄電池３が充電可能なときは充電する。電力使用料金の安くない時間帯であるときは（ｆ）や（ｈ）のように蓄電池３の充電をせず電力料金の安い時間帯を待つ。   On the other hand, the power supply controls (e) to (h) are when the electric device 5 is not operating or when the power used is small even though it is operating. At this time, referring to the power usage fee information, when it is a time zone where the power usage fee is cheap, priority is given to the charging of the storage battery 3 as in (e) and (g), so that the storage battery can be used when the power usage fee is low. When 3 can be charged, it is charged. When it is a time zone where the power usage fee is not cheap, the battery 3 is not charged as in (f) and (h), and a time zone where the power fee is cheap is waited.

図８の（ｉ）のように電気機器５が蓄電池３と接続されていない、蓄電池３が接続されていても満充電のときは充電の必要がないので電気機器５の動作を優先する。   As shown in FIG. 8 (i), the electric device 5 is not connected to the storage battery 3, and even when the storage battery 3 is connected, charging is not necessary when fully charged, so the operation of the electric device 5 is prioritized.

以上のような優先順位に従って以下に図７の制御ステップを説明する。   The control steps of FIG. 7 will be described below according to the priority order as described above.

ステップＳ２において上記のように優先権の判断と電力供給制御を決定し、Ｓ３において電気機器の制御手段１９によって電気機器の運転制御を行う。Ｓ４において充電手段の制御手段２１によって充電手段１６の充電制御を行う。   In step S2, priority determination and power supply control are determined as described above, and operation control of the electric device is performed by the control unit 19 of the electric device in S3. In S4, the charging means 16 is controlled by the charging means control means 21.

Ｓ５において総使用電力検知手段１７によって電気機器５の使用電力（充電手段の使用電力を含む）を検知したり、電気機器の使用電力検知手段２０と充電手段の使用電力検知手段２２によって電気機器と充電手段の使用電力の合計を検知する。   In S5, the total power consumption detection means 17 detects the power consumption of the electrical equipment 5 (including the power consumption of the charging means), or the electrical equipment usage power detection means 20 and the charging means usage power detection means 22 The total power used by the charging means is detected.

Ｓ６において、電力供給制御手段２３は合計の使用電力を所定値である許容電力と比較をして使用電力のほうが大きい場合にはＳ２に戻って電力供給制御を見直す（電気機器の制御と充電手段の制御を調整する）。   In S6, the power supply control means 23 compares the total used power with the allowable power that is a predetermined value, and if the used power is larger, the power supply control means 23 returns to S2 to review the power supply control (control and charging means of the electric device). Adjust control).

Ｓ７のように、合計の使用電力を所定値である許容電力と比較をして使用電力のほうが小さい場合には、電力供給の制御がうまくいったので、使用者指示手段（リモコン）２６などによって使用者に電気機器５の運転状態や使用電力量を報知し、蓄電池３の充電状態や充電時間、蓄電池に供給している電力量を報知する。   As shown in S7, when the total power consumption is compared with the allowable power that is a predetermined value and the power consumption is smaller, the power supply has been successfully controlled. Therefore, the user instruction means (remote controller) 26 or the like is used. The user is notified of the operating state of the electrical device 5 and the amount of power used, and the state of charge of the storage battery 3, the charging time, and the amount of power supplied to the storage battery are notified.

また、充電状態検知手段１６にて充電状態を検知して、定電流充電モードや定電圧充電モード、パルス充電モードにあわせた電流・電圧制御を行う。   In addition, the charge state is detected by the charge state detection means 16, and current / voltage control is performed in accordance with the constant current charge mode, constant voltage charge mode, and pulse charge mode.

Ｓ８において、充電状態検知手段１６にて充電状態を検知して、定電流充電モードから定電圧充電モードやパルス充電モードに充電モードが切り替わったときはＳ１に戻り優先権の判断と電力供給制限を再び判断する。同様に、電気機器５の運転モードが切り替わったときも電気機器の制御手段１９からこれの通知を受理してＳ１に戻り優先権の判断と電力供給制限を再び判断する。   In S8, when the charge state is detected by the charge state detection means 16, and the charge mode is switched from the constant current charge mode to the constant voltage charge mode or the pulse charge mode, the process returns to S1 to determine priority and limit power supply. Judge again. Similarly, when the operation mode of the electrical device 5 is switched, the notification is received from the control means 19 of the electrical device, and the process returns to S1 to determine the priority and the power supply limitation again.

Ｓ９において、充電状態検知手段１６にて充電完了を検知したときは蓄電池への充電を終了してＳ１に戻って、優先権の判断と電力供給制限を再び判断する。同様に、電気機器５の運転が終了完了したときも電気機器の制御手段１９からこれの通知を受理してＳ１に戻って、優先権の判断と電力供給制限を再び判断する。   In S9, when the charging state detecting means 16 detects the completion of charging, the charging of the storage battery is finished and the process returns to S1, and the determination of the priority right and the power supply restriction are determined again. Similarly, when the operation of the electric device 5 is completed, the notification is received from the control means 19 of the electric device, the process returns to S1, and the priority determination and the power supply limitation are determined again.

以上のＳ８、Ｓ９のように、充電状態検知手段１６と充電手段の使用電力検知手段２２によって蓄電池３の充電モードが変化したり充電完了したことを検知した場合、Ｓ１に戻って優先権の判断と電力供給制限を判断する。また、電気機器の制御手段１９と電気機器の使用電力検知手段２０によって電気機器の運転モードが変化したり運転が完了したことを検知した場合、Ｓ１に戻って優先権の判断と電力供給制限を判断する。   As in S8 and S9 above, when it is detected that the charging mode of the storage battery 3 has been changed or the charging has been completed by the charging state detection means 16 and the used power detection means 22 of the charging means, the process returns to S1 to determine priority. And determine power supply restrictions. Further, when it is detected that the operation mode of the electrical device has changed or the operation has been completed by the control unit 19 of the electrical device and the power consumption detection unit 20 of the electrical device, the process returns to S1 to determine the priority and limit the power supply. to decide.

Ｓ１に戻って優先権の判断と電力供給制限を再び判断すると、蓄電池３への充電を優先したことによって電気機器５の使用電力が制限されている場合（たとえば給湯機器の保温モードである場合）はこの制限を解除して電気機器５を通常に運転する（沸き上げモードに切り換える）。また、蓄電池３への充電を優先することによって電気機器５が運転待ち状態（スタンバイモード）になっている場合はこの待ち状態を解除して電気機器を運転開始する。   When the priority right determination and the power supply restriction are determined again after returning to S1, the power used by the electric device 5 is restricted by giving priority to the charging of the storage battery 3 (for example, in the case of the warming mode of the hot water supply device). Removes this restriction and operates the electric device 5 normally (switches to the boiling mode). Further, when the electric device 5 is in the operation waiting state (standby mode) by giving priority to the charging of the storage battery 3, the waiting state is canceled and the electric device is started to operate.

なお、フローチャートには図示しないが使用者指示手段２６（リモコン）によって、充電中や電気機器の運転中に使用者の指示にてよってＳ１に戻ってもよい。   Although not shown in the flowchart, the user instruction means 26 (remote controller) may return to S1 according to an instruction of the user during charging or operation of the electric device.

また、図７のフローチャートの代わりに図９のフローチャートで動作させてもよい。すなわち、Ｓ２において、優先権の判断と電力供給制御を決定した後、Ｓ５１にて、電気機器５の本来機能部の使用電力と充電手段の使用電力を演算し合計して充電機能付き電気機器の使用電力を算出する。   Further, the operation may be performed according to the flowchart of FIG. 9 instead of the flowchart of FIG. That is, after determining the priority and controlling the power supply in S2, in S51, the power used by the original functional unit of the electric device 5 and the power used by the charging means are calculated and summed up to calculate the electric power with charging function. Calculate power consumption.

これには、使用電力演算手段２８は、電気機器の機能ブロック１８と充電手段１６の使用電力について、運転時間（充電時間）と使用電力との関係を動作シーケンスとして予め記憶しておく。   For this purpose, the power consumption calculation means 28 stores in advance the relationship between the operation time (charging time) and the power consumption as the operation sequence for the power consumption of the functional block 18 and the charging means 16 of the electrical device.

また、使用電力演算手段２８は、電気機器の制御手段１９からの運転モードに関する情報や電気機器の使用電力検知手段２０からの運転開始に関する情報を取得し、電気機器の機能ブロック１８の動作シーケンス上の現在状態を判定し、今後の運転時間と使用電力を考慮する。   In addition, the power consumption calculation means 28 acquires information on the operation mode from the control means 19 of the electric equipment and information on the operation start from the power usage detection means 20 of the electric equipment, and the operation sequence of the functional block 18 of the electric equipment is obtained. The current state of the vehicle is determined, and the future operation time and power consumption are taken into consideration.

同様に、使用電力演算手段２８は、充電手段１６についても、充電状態検知手段１６からの充電モードに関する情報や充電手段の使用電力検知手段２２からの充電開始に関する情報を取得し、充電手段１６の動作シーケンス上の現在状態を判定し、今後の充電時間と使用電力を考慮する。   Similarly, for the charging unit 16, the used power calculation unit 28 acquires information on the charging mode from the charging state detection unit 16 and information on the charging start from the used power detection unit 22 of the charging unit. The current state on the operation sequence is determined, and the future charging time and power consumption are considered.

電気機器の動作シーケンスは、たとえば電気給湯機器であれば、お湯の沸き上げ開始から沸き上げ完了、保温モードに遷移する時間と使用電力のテーブルである。   For example, in the case of an electric hot water supply device, the operation sequence of the electric device is a table of electric power consumption and a time for transition from the start of boiling water to the completion of boiling, and the transition to the heat retention mode.

エアコンであれば冷房、暖房、除湿、送風など各運転種別毎の使用電力や、温度設定と風量変化に対応する使用電力、さらに、急速モードやお休みモードなどシーケンシャルモードの運転時間と使用電力のテーブルである。   In the case of an air conditioner, the power consumption for each operation type such as cooling, heating, dehumidification, air blowing, power consumption corresponding to temperature setting and air volume change, and operation time and power consumption of sequential mode such as rapid mode and rest mode It is a table.

蓄電池の充電シーケンスについては図６の通りである。   The charging sequence of the storage battery is as shown in FIG.

そして、Ｓ６１において、電力供給制御手段２３は合計の使用電力を許容電力と比較を
して使用電力のほうが大きい場合にはＳ２に戻って電力供給制御を見直す（電気機器の制御と充電手段の制御内容を調整する）。 In S61, the power supply control means 23 compares the total used power with the allowable power, and if the used power is larger, the power supply control means 23 returns to S2 to review the power supply control (control of the electric device and control of the charging means). Adjust the content).

合計の使用電力を所定値である許容電力と比較をして使用電力のほうが小さい場合には、電力供給の制御の割り当てがうまくいったので、Ｓ３１、Ｓ４１で電気機器の運転動作制御と充電手段の制御を行う。   When the total used power is compared with the allowable power that is a predetermined value and the used power is smaller, the allocation of power supply control is successful, so that the operation control of the electric equipment and the charging means are performed in S31 and S41. Control.

図９のフローチャートのメリットは、図７が電気機器、充電手段を動作させながら電力調整を行うのに対して、図９では電力調整の演算が完了して動作させることができることである。また、電気機器の使用電力を検知する検知手段２０、充電手段の使用電力を検知する使用電力検知手段２２、総使用電力検知手段１７が不要となる。   The advantage of the flowchart of FIG. 9 is that the power adjustment is performed while the electric device and the charging unit are operated in FIG. 7, whereas the operation of the power adjustment is completed in FIG. Further, the detection means 20 for detecting the power used by the electric device, the power usage detection means 22 for detecting the power usage of the charging means, and the total power consumption detection means 17 are not required.

以下、本願の実施の形態２〜５においても図７のフローチャートを基にして説明するが、これらを図９のフローチャートのようにＳ３〜Ｓ６の順序を入れ替えても構わない。   Hereinafter, Embodiments 2 to 5 of the present application will also be described based on the flowchart of FIG. 7, but these may be switched in the order of S <b> 3 to S <b> 6 as in the flowchart of FIG. 9.

以上のように、本実施の形態１によれば以下の効果がある。   As described above, the first embodiment has the following effects.

（１）交流電源に接続して蓄電池３に電力供給可能な充電手段１６を備え、電気機器５の使用電力、蓄電池３の充電状態、交流電源の時間帯別電力使用料金情報、の少なくとも一つに応じて充電手段に供給する電力を制御する電力供給制御手段２８を備える。   (1) It is provided with a charging means 16 that can be connected to an AC power source and can supply power to the storage battery 3, and is at least one of the power usage of the electrical device 5, the state of charge of the storage battery 3, and the power usage fee information according to the AC power supply time zone Power supply control means 28 for controlling the power supplied to the charging means according to the above.

これにより、電気機器５に充電手段１６を設けるので、この充電手段付き電気機器５を予め設置しておけば後に電気自動車や電動自転車を購入したときに、この電気機器の充電手段１６に電気自動車や電動自転車などを接続すれば大がかりな電気工事を必要とせずに駐車場、駐輪場で充電することができる。   As a result, the charging device 16 is provided in the electric device 5. Therefore, if the electric device 5 with the charging device is installed in advance, when the electric vehicle or the electric bicycle is purchased later, the electric vehicle is connected to the charging device 16 of the electric device. Or electric bicycles can be connected and charged at parking lots and bicycle parking lots without the need for extensive electrical work.

また、電気機器本体（電気機器の機能ブロック１８と制御手段１９）の動作による使用電力、蓄電池３の充電状態、交流電源の時間帯別電力使用料金情報に応じて充電手段１６に供給する電力を制御するので、充電中に電気機器を使用して電力を使いすぎてブレーカーが遮断することを防いだり、電力使用料金の安い時間帯を選択して充電したり、蓄電池３の充電状態に応じて電気機器本体の動作よりも充電のほうを優先する等の制御が可能となる。   In addition, the power supplied to the charging means 16 according to the power used by the operation of the electrical equipment main body (the functional block 18 and the control means 19 of the electrical equipment), the state of charge of the storage battery 3, and the power usage fee information according to time zone of the AC power supply Because it controls, it prevents the breaker from shutting off by using too much electric power during charging, selecting the time zone where the power usage fee is low, or charging depending on the charging state of the storage battery 3 Control such as giving priority to charging over the operation of the electric device main body becomes possible.

（２）充電手段付き電気機器５は屋外に少なくとも一部が設置される電気機器、たとえば照明機器、空調機器、給湯機器、または貯湯機器とし、大がかりな電気工事を必要とせずに屋外で充電することが可能となる。また屋外の電気機器に接続するので、電源コンセントに接続された延長ケーブルを屋内から屋外に通しておく必要がなく防犯上好ましい。   (2) The electric device 5 with charging means is an electric device that is at least partially installed outdoors, such as a lighting device, an air conditioner, a hot water supply device, or a hot water storage device, and is charged outdoors without requiring extensive electrical work. It becomes possible. Further, since it is connected to an outdoor electric device, it is not necessary to pass an extension cable connected to a power outlet from indoor to outdoor, which is preferable in terms of crime prevention.

（３）電力供給制御手段２８は、蓄電池の充電状態を検知して定電流充電モードで充電するときは、時間帯別電力使用料金情報によって電力使用料金が安くなる時間帯を選択して充電手段から電力を供給するので、充電のうちで大きな電力を必要とする定電流充電モードにかかる電力使用料金を下げることができる。   (3) When the power supply control means 28 detects the state of charge of the storage battery and charges the battery in the constant current charging mode, the power supply control means 28 selects the time zone when the power usage fee is reduced according to the power usage fee information classified by time zone, and the charging means Since the electric power is supplied from the power source, it is possible to reduce the power usage fee for the constant current charging mode that requires a large amount of power during charging.

（４）電力供給制御手段２８は、充電手段付き電気機器（電気機器の機能ブロック１８と制御手段１９）の使用電力と充電手段１６から供給する電力の総和を演算し交流電源の供給能力以下に維持するよう電気機器１８の動作を制御する、または（および）充電手段１６による電力供給を制御する。   (4) The power supply control means 28 calculates the sum of the power used by the electric equipment with the charging means (the functional block 18 of the electric equipment and the control means 19) and the power supplied from the charging means 16 to be less than the supply capacity of the AC power supply. Control the operation of the electrical device 18 to maintain, or (and) control the power supply by the charging means 16.

これにより、充電中に電気機器を使用するときは交流電源（分岐ブレーカーを含む）の供給能力を超えないよう電気機器の動作と充電手段の電力供給を制御してブレーカーの遮
断を防ぐことができる。 As a result, when the electric device is used during charging, the breaker can be prevented from being interrupted by controlling the operation of the electric device and the power supply of the charging means so as not to exceed the supply capacity of the AC power supply (including the branch breaker). .

（５）電力供給制御手段２８は、蓄電池３の充電状態を検知して定電流充電モードで充電するときは、電気機器（電気機器の機能ブロック１８と制御手段１９）の使用電力よりも充電手段１６による電力供給を優先し、充電手段付き電気機器の使用電力と充電手段から供給する電力の総和を交流電源の供給能力以下に維持する。   (5) When the power supply control means 28 detects the state of charge of the storage battery 3 and charges it in the constant current charging mode, the power supply control means 28 uses the charging means rather than the power used by the electrical equipment (the functional block 18 of the electrical equipment and the control means 19). Priority is given to the power supply by No. 16, and the sum of the electric power used by the electric device with the charging means and the electric power supplied from the charging means is kept below the supply capacity of the AC power supply.

これにより、大電力を必要とする定電流充電モードで充電するときは交流電源（分岐ブレーカーを含む）の供給能力を超えないよう電気機器の使用電力よりも充電手段による電力供給を優先することで充電残量が少なくなった蓄電池の充電をスムーズに行わせることができる。   As a result, when charging in the constant current charging mode that requires a large amount of power, the power supply by the charging means is given priority over the power used by the electrical equipment so as not to exceed the supply capacity of the AC power supply (including the branch breaker). The storage battery whose remaining charge is low can be charged smoothly.

（６）電力供給制御手段２８は、時間帯別電力使用料金情報によって電力使用料金が安くなる時間帯においては、電気機器（電気機器の機能ブロック１８と制御手段１９）の使用電力よりも充電手段１６による電力供給を優先し、充電手段付き電気機器の使用電力と充電手段から供給する電力の総和を交流電源の供給能力以下に維持する。   (6) The power supply control means 28 is a charging means rather than the power used by the electrical equipment (the functional block 18 of the electrical equipment and the control means 19) in the time zone when the power usage fee is reduced by the time-based power usage fee information. Priority is given to the power supply by No. 16, and the sum of the electric power used by the electric device with the charging means and the electric power supplied from the charging means is kept below the supply capacity of the AC power supply.

これにより、電力使用料金が安くなる時間帯においては、電気機器の使用電力よりも充電手段による電力供給を優先して充電コストを小さくし、充電中に電気機器を使用するときは交流電源（分岐ブレーカーを含む）の供給能力を超えないよう電気機器の動作と充電手段の電力供給を制御してブレーカーの遮断を防ぐことができる。たとえば夜間の電力使用料金が安くなる時間帯を利用すると翌朝から蓄電池（電気自動車など）を使用することができる。   As a result, in the time period when the electricity usage fee is cheaper, the power supply by the charging means is prioritized over the electricity used by the electric device to reduce the charging cost, and when using the electric device during charging, the AC power supply (branch) It is possible to prevent the breaker from being interrupted by controlling the operation of the electrical equipment and the power supply of the charging means so as not to exceed the supply capacity of the breaker (including the breaker). For example, when a time zone in which the nighttime power usage fee is reduced is used, a storage battery (such as an electric vehicle) can be used from the next morning.

（７）電力供給制御手段２８は、時間帯別電力使用料金情報によって電力使用料金が安くなる時間帯以外においては、充電手段１６による電力供給よりも電気機器（電気機器の機能ブロック１８と制御手段１９）の使用電力を優先し、充電手段付き電気機器の使用電力と充電手段から供給する電力の総和を交流電源の供給能力以下に維持する。   (7) The power supply control unit 28 is configured to use the electric device (the function block 18 of the electric device and the control unit) rather than the power supply by the charging unit 16 except for the time period in which the power usage fee is reduced by the time-based power usage fee information. Priority is given to the power used in 19), and the sum of the power used by the electric device with the charging means and the power supplied from the charging means is maintained below the supply capacity of the AC power supply.

これにより、電力使用料金が安くなる時間帯以外においては充電手段による電力供給よりも電気機器の使用電力を優先して、使用者が電気機器を使いたいときにストレスなく使える。電気機器の使用中に充電するときは交流電源（分岐ブレーカーを含む）の供給能力を超えないよう電気機器の動作と充電手段の電力供給を制御してブレーカーの遮断を防ぐことができる。たとえば昼間の電力使用料金が安くない時間帯では、充電コストを小さくするために電力使用料金が安くなる時間帯になるまでできるだけ充電しない。   As a result, it can be used without stress when the user wants to use the electric device by giving priority to the electric power used by the electric device over the power supply by the charging means except during the time period when the electric power usage fee is reduced. When charging while using the electric device, the breaker can be prevented from being interrupted by controlling the operation of the electric device and the power supply of the charging means so as not to exceed the supply capacity of the AC power supply (including the branch breaker). For example, in a time zone in which the daytime power usage fee is not cheap, in order to reduce the charging cost, charging is not performed as much as possible until the time zone in which the power usage fee is low.

（実施の形態２）
次に本発明の実施の形態２を説明する。実施の形態１の構成（図２）と同じ手段については付与する番号を実施の形態１と同じとして詳細な説明を省く。 (Embodiment 2)
Next, a second embodiment of the present invention will be described. With respect to the same means as in the configuration of the first embodiment (FIG. 2), the number assigned is the same as in the first embodiment, and a detailed description is omitted.

実施の形態２は、実施の形態１において図８の電力供給制御を図１０とするものである。すなわち、図１０の（ａ’）（ｃ’）（ｅ’）（ｇ’）のように、交流電源の時間帯別電力使用料金が安い時間帯においては充電（または電気機器）を優先させるとともに、優先させないほうの電気機器を運転させ（または蓄電池を充電させ）て交流電源の供給能力にほぼ等しくなるよう合計の使用電力を調整するものである。   In the second embodiment, the power supply control in FIG. 8 in the first embodiment is shown in FIG. That is, as shown in (a ′), (c ′), (e ′), and (g ′) of FIG. 10, priority is given to charging (or electrical equipment) in a time zone where the power usage fee for each AC power source is low. The electric power that is not prioritized is operated (or the storage battery is charged), and the total power used is adjusted so as to be approximately equal to the supply capacity of the AC power supply.

そのため、図２の構成において、使用電力演算手段２８は充電を含めた電気機器５全体の現在の使用電力と今後の使用電力を得て、その総和が所定値（＝交流電源の供給能力）にほぼ等しくなるよう以下の電力供給の制御を行う。   Therefore, in the configuration of FIG. 2, the power consumption calculation means 28 obtains the current power consumption and the future power consumption of the entire electric device 5 including charging, and the sum is set to a predetermined value (= AC power supply capability). The following power supply control is performed so as to be approximately equal.

（イ）電気機器の使用電力検知手段２０において電気機器の使用電力（電気機器の機能ブロック１８と電気機器の制御手段１９）を検知し、充電手段の使用電力検知手段２２において充電手段の使用電力を検知し、その総和の使用電力を演算して、電力使用料金が安い時間帯においては使用電力の総和が所定値以下であるときは電気機器５と充電手段１６とを同時に運転させる。ここで、総和の使用電力を演算する代わりに総使用電力検知手段１７で検知する総和の使用電力を用いてもよい。   (A) The electric power consumption detecting means 20 detects electric power consumption (electrical device functional block 18 and electric equipment control means 19), and the charging power usage detecting means 22 uses the charging power. , And the electric power 5 and the charging means 16 are operated simultaneously when the total electric power used is less than or equal to a predetermined value in a time zone when the electric power usage fee is low. Here, instead of calculating the total power consumption, the total power consumption detected by the total power detection means 17 may be used.

（ロ）電力使用料金が安い時間帯において、電気機器５と充電手段１６とを同時に通常運転させると使用電力の総和が所定値以上であるときは、電気機器５と充電手段１６との両方で使用する電力を割り当て調整して所定値にほぼ等しくなるよう運転させる。   (B) When the electric device 5 and the charging means 16 are normally operated simultaneously at a time when the electric power usage fee is low, if the total amount of electric power used is equal to or greater than a predetermined value, both the electric device 5 and the charging means 16 The electric power to be used is allocated and adjusted so as to be almost equal to a predetermined value.

たとえば、電気機器が電気給湯機器であれば、お湯の沸き上げモードから保温モードに切り替えて使用電力が減ったときは充電手段に供給する電力を増やす。電気機器がエアコンであれば運転モードや設定温度、風量を変更して使用電力が変化したときは充電手段に供給する電力を増減させる。蓄電池で充電する電力が変化したときは電気機器で使用する電力を増減させる。   For example, if the electric device is an electric hot water supply device, the electric power supplied to the charging means is increased when the hot water heating mode is switched from the hot water heating mode to the heat retention mode and the electric power used is reduced. If the electric device is an air conditioner, the power supplied to the charging means is increased or decreased when the operating mode, set temperature, or air volume is changed to change the power used. When the power charged by the storage battery changes, the power used by the electrical device is increased or decreased.

たとえば、図１１（ａ）のように、優先させる電気機器の使用電力が時間ｔ３において減ったときは蓄電池の充電電力を増やす。   For example, as shown in FIG. 11A, when the electric power used by the electric device to be prioritized decreases at time t3, the charging power of the storage battery is increased.

（ハ）電力使用料金が安い時間帯において、優先する蓄電池の充電（または電気機器の運転）の使用電力が減少した場合、優先させないほうの電気機器を運転させて（または蓄電池を充電させて）所定値以下でできるかぎり電力を使用する。   (C) When the power used for charging a preferred storage battery (or driving an electrical device) decreases during a period when the electricity usage fee is low, drive the non-prioritized electrical device (or charge the storage battery). Use power as much as possible below the specified value.

たとえば、蓄電池の充電を優先して行い、使用可能な電力に余裕が出てくれば電気機器５を運転させる。電気給湯機器であればお湯の保温モード、エアコンであれば換気や空気清浄モードのように対象物や周囲環境の保持動作を行う。また、エアコン機器の内部洗浄のように機器のメンテナンス動作であってもよい。あるいは、電気機器の運転を優先して行い、使用可能な電力に余裕がでてくれば蓄電池の充電を行う。   For example, the storage battery is preferentially charged, and the electric device 5 is operated if there is a surplus in usable power. In the case of an electric hot water supply device, the hot water is kept in a warming mode, and in the case of an air conditioner, the object and the surrounding environment are held as in a ventilation or air cleaning mode. Moreover, the maintenance operation | movement of an apparatus like the internal washing | cleaning of an air-conditioner apparatus may be sufficient. Alternatively, priority is given to the operation of the electric equipment, and the storage battery is charged if there is a surplus in usable power.

たとえば、図１１（ｂ）のように、蓄電池の充電を行い、時間ｔ４において充電の電力が減少して使用可能な電力に余裕が出てきたら電気機器の運転を開始する。   For example, as shown in FIG. 11 (b), the storage battery is charged, and the operation of the electric device is started when there is a surplus in the usable power at time t4 due to a decrease in the charging power.

本実施の形態２の充電付き電気機器の動作について図１２のフローチャートを示して説明する。実施の形態１のフローチャート図７と同じステップについては付与する番号を実施の形態１と同じとして詳細な説明を省く。   The operation of the electric device with charging according to the second embodiment will be described with reference to the flowchart of FIG. Flowchart of Embodiment 1 The same steps as those in FIG. 7 are designated by the same numbers as in Embodiment 1 and will not be described in detail.

図１２のＳ６において、電力供給制御手段２３は合計の使用電力が所定値以下であるように許容電力と比較をした後、Ｓ６２を追加して合計の使用電力の調整が可能であるかを判断する。   In S6 in FIG. 12, the power supply control means 23 compares the allowable power so that the total used power is less than or equal to a predetermined value, and then adds S62 to determine whether the total used power can be adjusted. To do.

すなわち、蓄電池に供給する充電電力を増加させることによって使用電力の調整が可能であるかを充電状態検知手段１６や充電手段の制御手段２１に問い合わせる。また、電気機器を運転させることによって使用電力の調整が可能であるかを電気機器の制御手段１９に問い合わせる。使用電力の調整が可能であればＳ２に戻って電力供給制御を調整する。   That is, it inquires of the charging state detection means 16 and the control means 21 of the charging means whether the use power can be adjusted by increasing the charging power supplied to the storage battery. Further, the control unit 19 of the electric device is inquired whether the electric power used can be adjusted by operating the electric device. If the power consumption can be adjusted, the process returns to S2 to adjust the power supply control.

なお、蓄電池の充電状態が図６の定電流充電モードは充電に必要とする電力が大きいので、使用可能電力が大きいときに調整に使うことができる。また、充電状態が定電圧充電モードやパルス充電モードでは充電に必要とする電力が小さいので、使用可能電力が小さいときでも調整に使うことができる。   In the constant current charging mode of FIG. 6 where the state of charge of the storage battery is large, the power required for charging is large, so that it can be used for adjustment when the available power is large. In addition, when the charging state is constant voltage charging mode or pulse charging mode, the power required for charging is small, so that it can be used for adjustment even when the available power is small.

以上のように、本実施の形態２によれば以下の効果がある。   As described above, the second embodiment has the following effects.

（１）電力供給制御手段２３は、時間帯別電力使用料金情報によって電力使用料金が安くなる時間帯においては、電気機器（電気機器の機能ブロック１８と制御手段１９）の使用電力と充電手段１６から供給する電力供給の総和を演算し、交流電源の供給能力にほぼ等しくするよう電気機器の動作、充電手段による電力供給を制御する。   (1) The power supply control means 23 uses the power used by the electrical equipment (the functional block 18 of the electrical equipment and the control means 19) and the charging means 16 in the time zone when the power usage fee is reduced by the time-based power usage fee information. The sum of the power supply supplied from the power source is calculated, and the operation of the electrical equipment and the power supply by the charging means are controlled so as to be approximately equal to the supply capacity of the AC power supply.

これにより、電力使用料金が安くなる時間帯を利用してできる限り電気機器を動作させたり蓄電池の充電を行うよう、充電手段付き電気機器の使用電力と充電手段から供給する電力供給の総和を演算し、交流電源の供給能力にほぼ等しく使用することで安い電力使用料金で電気機器を動作させ充電することができる。   As a result, the sum of the electric power used by the electric device with charging means and the electric power supply supplied from the charging means is calculated so that the electric device can be operated as much as possible and the storage battery can be charged using the time period when the electricity usage fee is cheap. In addition, the electric equipment can be operated and charged at a low power usage fee by using it almost equal to the supply capacity of the AC power supply.

（２）電力供給制御手段２３は、電気機器（電気機器の機能ブロック１８と制御手段１９）の使用電力と充電手段１６から供給する電力の総和を演算して交流電源の供給能力未満であるときに充電手段１６による電力供給を行って総和の電力が供給能力に近づくよう制御する。   (2) When the power supply control means 23 calculates the sum of the power used by the electrical equipment (the functional block 18 of the electrical equipment and the control means 19) and the power supplied from the charging means 16 and is less than the supply capacity of the AC power supply. Then, power is supplied by the charging means 16 so that the total power approaches the supply capacity.

これにより、電力使用料金が安くなる時間帯で交流電源の供給能力に余裕があるときは、充電手段による電力供給を行ってできるかぎり使用電力を増やすことで安い電力使用料金で充電することができる。   As a result, when there is a surplus in the power supply capacity of the AC power supply in the time zone when the power usage fee is cheaper, it is possible to charge at a low power usage fee by increasing the power usage as much as possible by supplying power by the charging means. .

（実施の形態３）
次に本発明の実施の形態３を説明する。実施の形態１と同じ手段については付与する番号を実施の形態１と同じとして詳細な説明を省く。 (Embodiment 3)
Next, a third embodiment of the present invention will be described. As for the same means as in the first embodiment, the number to be assigned is the same as in the first embodiment, and the detailed description is omitted.

実施の形態３は図１３のように、図１の電気機器（貯湯タンク５ｂ）に固定設置型の蓄電池９を接続し、電気自動車２が外出中で駐車場にない場合にも蓄電池９に一旦充電を行い、電気自動車２が駐車場に帰ってきてから蓄電池９から車載蓄電池３に充電するものである。   In the third embodiment, as shown in FIG. 13, a fixed installation type storage battery 9 is connected to the electric device (hot water storage tank 5 b) of FIG. 1, and even when the electric vehicle 2 is out and not in a parking lot, Charging is performed, and the in-vehicle storage battery 3 is charged from the storage battery 9 after the electric vehicle 2 returns to the parking lot.

このように蓄電池９を一時的な蓄電に使用することで、電力使用料金の安い時間に電気自動車２が駐車場に無くても充電できる。また、蓄電池９から車載蓄電池３に電力供給するときにその電力を大きくして短時間で充電できる利点がある。たとえば、家庭の交流電力は２００Ｖ−１５Ａが最大であるが、蓄電池９から２倍の電圧（または２倍の電流）で供給すれば充電時間を約半分にすることができる。   In this way, by using the storage battery 9 for temporary power storage, the battery can be charged even when the electric vehicle 2 is not in the parking lot at a time when the power usage fee is low. In addition, when power is supplied from the storage battery 9 to the in-vehicle storage battery 3, there is an advantage that the power can be increased and charging can be performed in a short time. For example, the maximum AC power at home is 200V-15A, but if it is supplied from the storage battery 9 at twice the voltage (or twice the current), the charging time can be reduced to about half.

そのため、実施の形態３の構成図は図１４のように、実施の形態１（図２）に蓄電池９とその充電系、放電系が追加される。   Therefore, in the configuration diagram of the third embodiment, as shown in FIG. 14, the storage battery 9 and its charging system and discharging system are added to the first embodiment (FIG. 2).

実施の形態１にある電気自動車の充電系を第一の充電とし、新たに蓄電池９の充電系を第二の充電と呼ぶことにする。   The charging system of the electric vehicle in the first embodiment is referred to as first charging, and the charging system of the storage battery 9 is newly referred to as second charging.

図１４において、第一の充電手段の使用電力検知手段、第一の充電手段・充電状態検知手段、第一の充電手段の制御手段は図２と同じなので、それぞれ２２、１６、２１の番号をそのまま付与する。   In FIG. 14, the used power detection means of the first charging means, the first charging means / charging state detection means, and the control means of the first charging means are the same as those in FIG. Grant as it is.

第二の充電手段の使用電力検知手段、第二の充電手段・充電状態検知手段・第二の充電手段の制御手段を、それぞれ新たに３０、３１とする。また、蓄電池９から車載蓄電池３に電力供給するときに短時間で充電できるよう電力を大きくする電力変換手段３２を備え
る。 The power consumption detecting means of the second charging means, the second charging means, the charging state detecting means, and the control means of the second charging means are newly designated 30, 31 respectively. Moreover, the power conversion means 32 which enlarges electric power so that it can charge in a short time when supplying electric power from the storage battery 9 to the vehicle-mounted storage battery 3 is provided.

蓄電池９用に新たに電気機器５が備える充電機能として、蓄電池９の充電手段とその制御手段である第二の充電手段・充電状態検知手段・制御手段３０を備える。第二の充電手段・制御手段３０には、蓄電池９の状態に応じて充電に最適な電圧・電流を作り出す電圧・電流変換機能のほかに、蓄電池９の充電状態を検知する充電状態検知手段を備える。   As a charging function newly provided in the electric device 5 for the storage battery 9, a charging unit for the storage battery 9 and a second charging unit / charge state detection unit / control unit 30 that are control units thereof are provided. The second charging means / control means 30 includes a charging state detection means for detecting the charging state of the storage battery 9 in addition to the voltage / current conversion function for generating the optimum voltage / current for charging according to the state of the storage battery 9. Prepare.

蓄電池９を蓄電池３と同じくリチウム電池とすれば充電状態とそれに応じた充電の電圧・電流については図６の充電シーケンスと同じにできる。   If the storage battery 9 is a lithium battery similar to the storage battery 3, the charging state and the charging voltage / current corresponding thereto can be made the same as the charging sequence of FIG.

また、蓄電池９の充電機能で使用する電力を検知するため、第二の充電手段３１の使用電力検知手段３０を第二の充電手段・制御手段３０の電源ラインに挿入する。総使用電力検知手段１７は、電気機器の使用電力と第一の充電手段の使用電力と第二の充電手段の使用電力の合計を計測する。   Further, in order to detect the power used for the charging function of the storage battery 9, the used power detection means 30 of the second charging means 31 is inserted into the power supply line of the second charging means / control means 30. The total used power detecting means 17 measures the sum of the used power of the electric equipment, the used power of the first charging means, and the used power of the second charging means.

電力変換手段３２は、蓄電池９に充電された電力を第一の充電手段１６に供給するもので、このとき電力変換を行って電流または電力を変換する。すなわち、定電流充電モードやパルス充電モードにおいては電圧を大きくし、定電圧充電モードにおいては電流を大きくすることで充電時間を短縮する。   The power conversion means 32 supplies the power charged in the storage battery 9 to the first charging means 16, and at this time performs power conversion to convert current or power. That is, the charging time is shortened by increasing the voltage in the constant current charging mode and the pulse charging mode and increasing the current in the constant voltage charging mode.

そして、電力供給手段２３は、電気機器の制御手段１８と第一の充電手段の制御手段２１の制御と電力供給に加えて、第二の充電手段の充電手段・制御手段３０の制御と電力供給、それに電力変換手段３２の制御を行う。すなわち、電気機器５の運転と、電気自動車の蓄電池３の充電と、蓄電池９の充電、そして蓄電池９から電気自動車の蓄電池３への充電を統合制御する。   The power supply means 23 controls and supplies power to the charging means / control means 30 of the second charging means in addition to the control and power supply of the control means 18 of the electrical equipment and the control means 21 of the first charging means. Then, the power conversion means 32 is controlled. That is, the operation of the electric device 5, the charging of the storage battery 3 of the electric vehicle, the charging of the storage battery 9, and the charging from the storage battery 9 to the storage battery 3 of the electric vehicle are integratedly controlled.

本実施の形態３の充電付き電気機器の動作について図１５のフローチャートを示して説明する。実施の形態１のフローチャート図７と同じステップについては付与する番号を実施の形態１と同じとして詳細な説明を省く。   The operation of the electric device with charging according to the third embodiment will be described with reference to the flowchart of FIG. Flowchart of Embodiment 1 The same steps as those in FIG. 7 are designated by the same numbers as in Embodiment 1 and will not be described in detail.

Ｓ１１において、図７のＳ１に加えて、蓄電池９の充電状態を検知する。   In S11, in addition to S1 of FIG. 7, the charged state of the storage battery 9 is detected.

Ｓ４２において、Ｓ４の代わりに、第一の充電手段１６、第二の充電手段３１の充電制御を行う。   In S42, charging control of the first charging unit 16 and the second charging unit 31 is performed instead of S4.

Ｓ５２において、Ｓ５の代わりに、電気機器５と第一の充電手段１６と第二の充電手段３１それぞれの使用電力と、合計の使用電力を検知する。   In S52, instead of S5, the power used by the electric device 5, the first charging unit 16, and the second charging unit 31 and the total power used are detected.

Ｓ７１において、Ｓ７の代わりに、電気機器５の運転状態と第一の充電手段１６の充電状態と第二の充電手段３１の受電状態を報知する。   In S71, instead of S7, the operating state of the electric device 5, the charging state of the first charging unit 16, and the power receiving state of the second charging unit 31 are notified.

図７のＳ８、Ｓ９については図示を省略している。   Illustration of S8 and S9 in FIG. 7 is omitted.

Ｓ２０を追加して、蓄電池９が満充電になるまでＳ１１に戻って充電を行う。   S20 is added and charging is performed by returning to S11 until the storage battery 9 is fully charged.

Ｓ２１を追加して、満充電後に、電気自動車２が接続手段８によって充電可能な状態であることを確認し充電のトリガーがあるか否かを確認する。   S21 is added, and after full charge, it is confirmed that the electric vehicle 2 is in a state that can be charged by the connecting means 8, and it is confirmed whether there is a trigger for charging.

充電のトリガーとして以下のものが考えられる。   The following are possible triggers for charging.

（イ）使用者指示手段（リモコン）２６によって使用者の指示があったとき。   (A) When the user gives an instruction from the user instruction means (remote controller) 26.

（ロ）電気自動車２を使用する時間の前に蓄電池３がそれに十分に充電されていないとき。ここで、電気自動車２を使用する時間は、使用者指示手段２６などによって電気自動車２の使用スケジュールが入力されている、過去の電気自動車２の使用履歴（使用時間と走行距離）によって使用スケジュールの予測ができる。   (B) When the storage battery 3 is not sufficiently charged before the electric vehicle 2 is used. Here, the usage time of the electric vehicle 2 is based on the past usage history (usage time and mileage) of the electric vehicle 2 in which the usage schedule of the electric vehicle 2 is input by the user instruction means 26 or the like. Can predict.

（ハ）設定された所定の時刻になったとき。たとえば、平日では午前１０時になったとき。休日では午前８時になったとき。   (C) When the predetermined time is reached. For example, when it is 10 am on weekdays. When it is 8am on a holiday.

（ニ）電気自動車２の蓄電池３の充電容量が所定値以下となったとき。たとえば、図６で７５％以下となって定電流充電モードになったとき。   (D) When the charge capacity of the storage battery 3 of the electric vehicle 2 becomes a predetermined value or less. For example, when the constant current charging mode is set to 75% or less in FIG.

以上のような充電のトリガーがあれば、Ｓ２２において、蓄電池９に充電した電力を電力変換手段３２で電力変換を行って第一の充電手段１６から電気自動車の蓄電池３を充電する。この充電に要する時間は、交流電源１１から電力供給するよりも短縮される。   If there is a charging trigger as described above, in S22, the electric power charged in the storage battery 9 is converted by the power conversion means 32, and the storage battery 3 of the electric vehicle is charged from the first charging means 16. The time required for this charging is shorter than the power supply from the AC power supply 11.

なお、Ｓ２の優先権の判断においては実施の形態１と同じである。優先順位記憶手段２４から電気機器５の運転と電気自動車の蓄電池３の充電と蓄電池９の充電の優先順位を取得し、Ｓ１１での電気機器の使用電力と蓄電池の充電状態と電力使用料金情報から優先順位を判断する。そして、その判断に基づいて電力供給制御手段２３が電気機器の制御手段１９と第一の充電手段の制御手段２１と第二の充電手段の制御手段３１の電力供給制御を行う。   Note that the priority determination in S2 is the same as in the first embodiment. The priority order of the operation of the electric device 5, the charging of the storage battery 3 of the electric vehicle, and the charging of the storage battery 9 is acquired from the priority storage means 24, and the electric power usage of the electric device, the charging state of the storage battery, and the power usage fee information Determine priority. Then, based on the determination, the power supply control means 23 performs power supply control of the control means 19 of the electrical equipment, the control means 21 of the first charging means, and the control means 31 of the second charging means.

優先順位は実施の形態１（図８）と基本的に同じである。図８中の電力供給制御で「充電」するときに蓄電池９と電気自動車の蓄電池３と二つの充電があるが、いずれか一方の蓄電池のみ充電可能であればその蓄電池を充電の対象とする。   The priority order is basically the same as in the first embodiment (FIG. 8). When “charging” is performed by the power supply control in FIG. 8, there are two chargings, the storage battery 9 and the storage battery 3 of the electric vehicle. If only one of the storage batteries can be charged, that storage battery is the target of charging.

両方の蓄電池とも充電可能であれば、充電の対象となるのは、
（イ）時間帯別電力使用料金が安い時間帯であれば、使用電力の大きい定電流充電モードの蓄電池を定電圧充電モードの蓄電池よりも優先して充電を行う。 If both storage batteries can be charged,
(B) If the power usage fee for each time zone is low, charging is performed with priority given to the storage battery in the constant current charging mode with the higher power usage than the storage battery in the constant voltage charging mode.

（イ−１）上記（イ）において、両方の蓄電池とも定電流充電モードであれば、電気自動車の蓄電池３を蓄電池９よりも優先して充電する。   (A-1) In the above (A), if both storage batteries are in the constant current charging mode, the storage battery 3 of the electric vehicle is charged with priority over the storage battery 9.

（イ−２）上記（イ）において、両方の蓄電池とも定電圧充電モード、パルス充電モードであれば、蓄電池９を電気自動車の蓄電池３よりも優先して充電する。   (B-2) In the above (B), if both the storage batteries are in the constant voltage charging mode and the pulse charging mode, the storage battery 9 is charged with priority over the storage battery 3 of the electric vehicle.

（ロ）時間帯別電力使用料金が安くない時間帯であれば、使用電力の小さい定電圧充電モード、パルス充電モードの蓄電池を定電流充電モードの蓄電池よりも優先して充電を行う。   (B) If the power usage fee for each time zone is not low, charging is performed with priority given to the storage battery in the constant voltage charging mode and the pulse charging mode with a lower usage power than the storage battery in the constant current charging mode.

（ロ−１）上記（ロ）において、両方の蓄電池とも定電圧充電モード、パルス充電モードであれば、蓄電池９を電気自動車の蓄電池３よりも優先して充電する。   (B-1) In (B) above, if both storage batteries are in the constant voltage charging mode and the pulse charging mode, the storage battery 9 is charged with priority over the storage battery 3 of the electric vehicle.

（ロ−２）上記（ロ）において、両方の蓄電池とも定電流充電モードであれば、電気自動車の蓄電池３を蓄電池９よりも優先して充電する。   (B-2) In (B) above, if both storage batteries are in constant current charging mode, the storage battery 3 of the electric vehicle is charged with priority over the storage battery 9.

以上のように、本実施の形態３によれば以下の効果がある。   As described above, the third embodiment has the following effects.

（１）交流電源に接続して、電動車両２の蓄電池３に電力供給可能な第一の充電手段１６と、電動車両２の蓄電池３とは別の蓄電池９に電力供給する第二の充電手段３１とを電気機器５に備え、電気機器５の使用電力、蓄電池３、９の充電状態、交流電源１１の時間帯別電力使用料金情報、の少なくとも一つに応じて第一、第二の充電手段１６、３１に供給する電力を制御する電力供給制御手段２３と、蓄電池に充電した電力を放電するときに交流電源以上の電力に変換して電動車両に電力供給する電力変換手段３２とを備えた充電手段付き電気機器である。   (1) A first charging means 16 that can be connected to an AC power source and can supply power to the storage battery 3 of the electric vehicle 2 and a second charging means that supplies power to a storage battery 9 different from the storage battery 3 of the electric vehicle 2 31 in the electric device 5, and the first and second charging according to at least one of the electric power used by the electric device 5, the state of charge of the storage batteries 3 and 9, and the power usage fee information according to the time zone of the AC power supply 11. The power supply control means 23 for controlling the power supplied to the means 16 and 31 and the power conversion means 32 for converting the power charged in the storage battery into electric power equal to or higher than the AC power source when supplying the electric power to the electric vehicle. It is an electric device with a charging means.

これにより、電気機器の使用電力、蓄電池の充電状態、交流電源の時間帯別電力使用料金情報に応じて第二の充電手段で交流電源から蓄電池に電力供給して充電し、第一の充電手段で蓄電池から電動車両に電力供給して充電する。このとき、電力変換手段で蓄電池に充電した電力を交流電源以上の電力に変換して電動車両に電力供給するので、交流電源から電動車両に直接電力供給するよりも短時間で充電できる。   Accordingly, the second charging means supplies power from the AC power source to the storage battery in accordance with the power usage of the electrical equipment, the state of charge of the storage battery, and the power usage fee information according to the time zone of the AC power source. Then, power is supplied from the storage battery to the electric vehicle for charging. At this time, since the power charged in the storage battery by the power conversion means is converted into power higher than the AC power supply and supplied to the electric vehicle, the battery can be charged in a shorter time than the direct power supply from the AC power supply to the electric vehicle.

（２）電力供給制御手段２３は、時間帯別電力使用料金情報によって電力使用料金が安くなる時間帯において、第一、第二の充電手段１６、３１に接続された蓄電池の一方が定電流充電モードであれば、定電流充電モードの蓄電池を定電圧充電モードまたはパルス充電モードの蓄電池よりも優先して電力供給する。   (2) The power supply control means 23 is configured such that one of the storage batteries connected to the first and second charging means 16 and 31 is constant-current charged in a time zone when the power usage fee is reduced by the time-based power usage fee information. In the mode, power is supplied to the storage battery in the constant current charging mode with priority over the storage battery in the constant voltage charging mode or the pulse charging mode.

これによって、電力使用料金が安くなる時間帯において、充電に大きな電力を必要とする定電流充電モードの蓄電池の充電を優先して電力使用料金を下げることができる。   This makes it possible to lower the power usage fee by prioritizing charging of the storage battery in the constant current charging mode that requires a large amount of power for charging in a time zone when the power usage fee is reduced.

（３）電力供給制御手段２３は、時間帯別電力使用料金情報によって電力使用料金が安くなる時間帯において、第一、第二の充電手段１６、３１に接続された蓄電池がともに定電流充電モードであれば、第一の充電手段を第二の充電手段よりも優先して電力供給する。   (3) The power supply control means 23 is configured so that both the storage batteries connected to the first and second charging means 16 and 31 are in the constant current charging mode in the time zone when the power usage fee is reduced by the power usage fee information classified by time zone. If so, the first charging means supplies power with priority over the second charging means.

これによって、電力使用料金が安くなる時間帯において、二つの蓄電池がともに定電流充電モードであれば電動車両の蓄電池に電力供給する第一の充電手段を優先して電動車両の充電にかかる電力使用料金を下げることができる。   As a result, when the two storage batteries are both in the constant current charging mode during the time period when the power usage fee is reduced, the first charging means that supplies power to the storage battery of the electric vehicle is given priority to use the electric power for charging the electric vehicle. The price can be reduced.

（実施の形態４）

実施の形態４は図１６のように、図１の複数の電気機器（エアコンの室外機５ａ、電気給湯機器の貯湯タンク５ｂ）の接続手段に充電プラグ４で接続し、いずれかを一つの電気機器を選択して蓄電池に電力供給する電力供給選択機器である。   In the fourth embodiment, as shown in FIG. 16, the charging plug 4 is connected to the connecting means of the plurality of electric devices (the outdoor unit 5a of the air conditioner and the hot water storage tank 5b of the electric hot water supply device) of FIG. A power supply selection device that selects a device and supplies power to a storage battery.

複数の電気機器は図１６の組合せに限らず、２台のエアコンの室外機の組合せや、２台の貯湯タンクの組合せでもよい。また、これに照明機器などを加えてもよい。また、２台に限らず３台以上であってもよい。電気機器の本来機能が異なる機器どうし等、同時に使用する確率が小さい電気機器どうしを組み合わせると、動作していないほうの電気機器から蓄電池に充電できる可能性を大きくできる。   The plurality of electric devices is not limited to the combination shown in FIG. 16, and may be a combination of two outdoor units of air conditioners or a combination of two hot water storage tanks. Moreover, you may add lighting equipment etc. to this. Moreover, not only two but three or more may be sufficient. Combining electrical devices that have a low probability of being used at the same time, such as devices having different original functions of electrical devices, can increase the possibility of charging the storage battery from the non-operating electrical device.

ここでは図１６で説明する。   Here, it will be described with reference to FIG.

実施の形態４の構成図は図１７のように、実施の形態１の電気機器である第一の電気機器５ａと、第二の電気機器５ｂと、その二つの電気機器のいずれかを選択して蓄電池３の充電に使用するかを決める電力供給選択機器１０、電気自動車の蓄電池３とからなる。   In the configuration diagram of the fourth embodiment, as shown in FIG. 17, the first electric device 5a, the second electric device 5b, and the two electric devices, which are the electric devices of the first embodiment, are selected. The power supply selection device 10 that determines whether to use the battery 3 for charging, and the storage battery 3 of the electric vehicle.

アンペアブレーカー１２、分岐ブレーカー１３ａ、１３ｂ、接続手段８ａ、８ｂ、蓄電池３は実施の形態１（図２）の同じ番号のものと同じ機能である。また、電力供給選択機器１０の備える充電手段の制御手段２１ｃ、充電手段・充電状態検知手段１６ｃ、接続手段８ｃは実施の形態１（図２）の同じ番号のものと同じ機能である。   The ampere breaker 12, the branch breakers 13a and 13b, the connection means 8a and 8b, and the storage battery 3 have the same functions as those of the same number in the first embodiment (FIG. 2). Further, the control means 21c, the charging means / charge state detecting means 16c, and the connecting means 8c of the charging means provided in the power supply selection device 10 have the same functions as those of the same numbers in the first embodiment (FIG. 2).

選択手段３３は蓄電池３を充電するときに、第一の電気機器５ａから供給される電力と第二の電気機器５ｂから供給される電力とを比較して大きい方を充電手段１６ｃに接続する。   When charging the storage battery 3, the selection means 33 compares the electric power supplied from the first electric device 5a with the electric power supplied from the second electric device 5b, and connects the larger one to the charging means 16c.

第一の電気機器５ａから供給可能な電力について、選択手段３３は接続手段８ａを介して第一の電気機器５ａの電力供給制御手段と情報のやりとりを行う。第二の電気機器５ｂから供給可能な電力について、選択手段３３は接続手段８ｂを介して第二の電気機器５ｂの電力供給制御手段と情報のやりとりを行う。   With respect to the power that can be supplied from the first electrical device 5a, the selection unit 33 exchanges information with the power supply control unit of the first electrical device 5a via the connection unit 8a. The selection means 33 exchanges information with the power supply control means of the second electrical device 5b via the connection means 8b regarding the power that can be supplied from the second electrical device 5b.

なお、図示しないが、電力供給選択機器１０は、実施の形態１（図２）の電気機器５ａ、５ｂと同様に、電力供給制御手段２３を選択手段３３に備えて、電気機器５ａ、５ｂの使用電力、蓄電池３の充電状態、交流電源１１の時間帯別電力使用料金情報、の少なくとも一つに応じて充電手段１６ｃに供給する電力を制御してもよい。   Although not shown, the power supply selection device 10 includes the power supply control means 23 in the selection means 33 as in the case of the electric devices 5a and 5b of the first embodiment (FIG. 2). You may control the electric power supplied to the charging means 16c according to at least one of used electric power, the charge condition of the storage battery 3, and the electric power usage charge information classified by time zone of the AC power supply 11.

本実施の形態４の電力供給選択機器の動作について図１８のフローチャートを示して説明する。実施の形態１のフローチャート図７と同じステップについては付与する番号を実施の形態１と同じとして詳細な説明を省く。   The operation of the power supply selection device according to the fourth embodiment will be described with reference to the flowchart of FIG. Flowchart of Embodiment 1 The same steps as those in FIG. 7 are designated by the same numbers as in Embodiment 1 and will not be described in detail.

Ｓ１２において、Ｓ１に加えて、第一、第二の電気機器５ａ、５ｂの使用電力を検知する。   In S12, in addition to S1, the power used by the first and second electric devices 5a and 5b is detected.

Ｓ１３において、選択手段３３は、電気機器５ａ、５ｂの電力供給の余裕を度算出して電力供給する電気機器を選択する。   In S13, the selection means 33 calculates the degree of power supply margin of the electric devices 5a and 5b, and selects the electric device that supplies power.

このとき、いずれか一方でも電気機器が動作無し（使用電力が小さい）であればその電気機器を電力供給の対象に選択する。両方の電気機器とも動作有り（使用電力が大きい）であれば、使用電力の小さい方を選択する。   At this time, if any one of the electric devices does not operate (power consumption is small), the electric device is selected as a power supply target. If both electrical devices are in operation (uses a large amount of power), select the one that uses less power.

電気機器の使用電力については図１の総使用電力検知手段１７または電気機器の使用電力検知手段２０によって計測し、接続手段８を介して選択手段３３と情報のやりとりを行う。   The electric power used by the electric equipment is measured by the total electric power detecting means 17 or the electric power used detecting means 20 shown in FIG. 1, and information is exchanged with the selecting means 33 via the connecting means 8.

Ｓ４３において、Ｓ４に代えて、電力供給選択機器１０の充電手段１６ｃを充電手段の制御手段２１ｃで制御し、第一の電気機器５ａまたは第二の電気機器５ｂのいずれかを選択して蓄電池３の充電に使用する。   In S43, instead of S4, the charging unit 16c of the power supply selection device 10 is controlled by the control unit 21c of the charging unit, and either the first electric device 5a or the second electric device 5b is selected and the storage battery 3 is selected. Used for charging.

なお、Ｓ２において、優先順位は実施の形態１（図８）と基本的に同じである。図８中で「電気機器の使用電力」については電気機器５ａと５ｂの二つがあるが、Ｓ１３で選択したほうの電気機器で優先順位を判断する。   In S2, the priority order is basically the same as in the first embodiment (FIG. 8). In FIG. 8, there are two types of “electric power used by electric devices”, namely electric devices 5a and 5b, and the priority order is determined by the electric device selected in S13.

以上のように、本実施の形態４によれば以下の効果がある。   As described above, the fourth embodiment has the following effects.

（１）複数の第１の発明の充電手段付き電気機器の充電手段５ａ、５ｂと接続し、いずれかを一つの電気機器を選択して蓄電池３に電力供給するので、複数の充電手段付きの電
気機器のうちで使用可能なものを選択して充電することができる。 (1) Since it connects with the charging means 5a, 5b of the electric equipment with several charging means of 1st invention, and selects one electric equipment and supplies electric power to the storage battery 3, it is equipped with several charging means. It is possible to select and use a usable electric device.

（実施の形態５）
次に本発明の実施の形態５を説明する。実施の形態１と同じ手段については付与する番号を実施の形態１と同じとして詳細な説明を省く。 (Embodiment 5)
Next, a fifth embodiment of the present invention will be described. As for the same means as in the first embodiment, the number to be assigned is the same as in the first embodiment, and the detailed description is omitted.

実施の形態５の構成図は図１９のように、実施の形態１（図１）に小規模発電装置４０（太陽光発電装置や燃料電池、地熱発電や風力発電など）を追加する。   In the configuration diagram of the fifth embodiment, as shown in FIG. 19, a small-scale power generation device 40 (solar power generation device, fuel cell, geothermal power generation, wind power generation, etc.) is added to the first embodiment (FIG. 1).

図２０のように、小規模発電装置４０で発電した電力は分岐ブレーカー１３を介して電気機器５に供給され、交流電源１１の代用電源として使用される。そして、小規模発電装置４０の発電量している時間は時間帯別電力使用料金が安くなるよう、小規模発電装置４０の発電量を発電量検知手段４１で検知し、電力使用料金情報記憶手段２５に入力する。   As shown in FIG. 20, the electric power generated by the small-scale power generation device 40 is supplied to the electric device 5 through the branch breaker 13 and used as a substitute power source for the AC power source 11. Then, the power generation amount of the small-scale power generation device 40 is detected by the power generation amount detection means 41 so that the power usage fee for each time zone is reduced during the time during which the power generation amount of the small-scale power generation device 40 is generated, and the power usage fee information storage means 25.

電力使用料金情報記憶手段２５は、発電量があるときは電力使用料金を安くし（たとえば０円）、発電量が無ければ通常の交流電源１１の電力使用料金とする。   The power usage fee information storage means 25 reduces the power usage fee when there is a power generation amount (for example, 0 yen), and uses the normal power usage fee of the AC power supply 11 when there is no power generation amount.

なお、電力供給制御手段２３は、総使用電力検知手段１７による使用電力の合計値と、発電量検知手段４１による発電量とを比較して、使用電力の合計値が発電量を超えないように制御する。   The power supply control means 23 compares the total value of power used by the total power consumption detection means 17 with the amount of power generated by the power generation amount detection means 41 so that the total value of power usage does not exceed the power generation amount. Control.

本実施の形態５の電力供給選択機器の動作について図２１のフローチャートを示して説明する。実施の形態１のフローチャート（図７）と同じステップについては付与する番号を実施の形態１と同じとして詳細な説明を省く。   The operation of the power supply selection device according to the fifth embodiment will be described with reference to the flowchart of FIG. For the same steps as those in the flowchart (FIG. 7) of the first embodiment, the number to be given is the same as that of the first embodiment, and the detailed description is omitted.

Ｓ１４を追加して、発電量検知手段４１で小規模発電装置４０の発電量を検知し、これを電気使用料金情報記憶手段２５に入力して、発電にともなう電力使用料金の変更を行う。   S14 is added, and the power generation amount detection means 41 detects the power generation amount of the small-scale power generation device 40 and inputs it to the electricity usage fee information storage means 25 to change the power usage fee accompanying power generation.

Ｓ６３において、Ｓ６の代わりに、電力供給制御手段２３は合計の使用電力を所定値である発電電力と比較をして使用電力のほうが大きい場合にはＳ２に戻って電力供給制御を見直す（電気機器の制御と充電手段の制御を調整する）。Ｓ６４は後述する。   In S63, instead of S6, the power supply control means 23 compares the total used power with the generated power that is a predetermined value, and if the used power is larger, the process returns to S2 to review the power supply control (electrical equipment) Control and control of charging means). S64 will be described later.

Ｓ７２において、Ｓ７の代わりに、使用者指示手段（リモコン）２６などによって使用者に電気機器５の運転状態や使用電力量を報知し、蓄電池３の充電状態や充電時間、蓄電池に供給している電力量に加えて、小規模発電装置４０の発電量や、使用電力量と発電量との差を報知する。   In S72, instead of S7, the user instruction means (remote control) 26 or the like informs the user of the operating state and power consumption of the electric device 5, and supplies the storage battery 3 to the storage battery, the charging state, the charging time, and the storage battery. In addition to the power amount, the power generation amount of the small-scale power generation device 40 and the difference between the power consumption amount and the power generation amount are notified.

以上だけでもよいが、小規模発電装置で発電した電力をできるかぎり使用・蓄電したいのでＳ６４を加える。これは実施の形態２（図１２）のＳ６２と似ている。すなわち、蓄電池に供給する充電電力を増加させることによって使用電力の調整が可能であるかを充電状態検知手段１６や充電手段の制御手段２１に問い合わせる。   However, S64 is added because it is desired to use and store the power generated by the small-scale power generator as much as possible. This is similar to S62 of the second embodiment (FIG. 12). That is, it inquires of the charging state detection means 16 and the control means 21 of the charging means whether the use power can be adjusted by increasing the charging power supplied to the storage battery.

電気機器を運転させることによって使用電力の調整が可能であるかを電気機器の制御手段１９に問い合わせる。使用電力の調整が可能であればＳ２に戻って電力供給制御を調整する。   The control unit 19 of the electric device is inquired whether the electric power used can be adjusted by operating the electric device. If the power consumption can be adjusted, the process returns to S2 to adjust the power supply control.

以上のように、本実施の形態５によれば以下の効果がある。   As described above, the fifth embodiment has the following effects.

（１）充電手段付き電気機器５は交流電源とは別に小規模発電装置４０に接続して電源
を得て、時間帯別電力使用料金情報においてその小規模発電装置４０が発電している時間帯は電力使用料金が安くなる時間帯と同じ扱いとする。 (1) The electric device 5 with the charging means is connected to the small-scale power generation device 40 separately from the AC power source to obtain the power source, and the time zone in which the small-scale power generation device 40 generates power in the power usage fee information by time zone Is treated the same as the time when electricity usage charges are cheaper.

これにより、太陽光発電や燃料電池などの小規模発電装置が発電して電力供給しているときはその発電した電力の電力使用料金を安くして、充電手段付き電気機器から蓄電池に電力を供給することができる。   As a result, when a small-scale power generation device such as solar power generation or fuel cell is generating and supplying power, the power usage fee of the generated power is reduced and power is supplied to the storage battery from the electric device with charging means can do.

（２）電力供給制御手段２３は、小規模発電装置４０の発電によって電力使用料金が安くなる時間帯においては、電気機器（電気機器の機能ブロック１８と制御手段１９）の使用電力と充電手段１６から供給する電力供給の総和を演算し、小規模発電装置４０の発電量にほぼ等しくするよう電気機器の動作、充電手段による電力供給を制御する。   (2) The power supply control means 23 uses the electric power used by the electrical equipment (the functional block 18 of the electrical equipment and the control means 19) and the charging means 16 in the time zone when the power usage fee is reduced by the power generation of the small-scale power generation device 40 The sum of the power supply supplied from the power source is calculated, and the operation of the electric equipment and the power supply by the charging means are controlled so as to be substantially equal to the power generation amount of the small-scale power generation device 40.

これにより、発電した電力をできる限り電気機器を動作させたり蓄電池の充電を行うよう、充電手段付き電気機器の使用電力と充電手段から供給する電力供給の総和を演算し、発電量にほぼ等しく使用することで安い電力使用料金で電気機器を動作させ充電することができる。   In this way, the total power used by the electrical equipment with charging means and the power supply supplied from the charging means are calculated so that the generated power can be operated as much as possible and the storage battery is charged. By doing so, the electric device can be operated and charged at a low power usage fee.

なお、上記実施の形態において、蓄電池の充電手段を電気機器と組み合わせるメリットを補足する。   In addition, in the said embodiment, the merit which combines the charging means of a storage battery with an electric equipment is supplemented.

電気機器が電気給湯機器であれば、外気温が下がって蓄電池の充放電に適さない温度に下がった場合は蓄電池周囲に導管などで貯湯タンクに蓄えたお湯を供給することで周囲温度を上昇させ充放電の効率を維持することができる。   If the electric device is an electric hot water supply device, the ambient temperature is raised by supplying hot water stored in a hot water storage tank with a conduit etc. around the storage battery when the outside air temperature drops and the temperature falls to an unsuitable temperature for charging or discharging the storage battery. Charge / discharge efficiency can be maintained.

また、電気機器がエアコンであれば、外気温が下がって蓄電池の充放電に適さない温度に下がった場合は室外機から出る排気熱を蓄電池周囲に導くことで周囲温度を上昇させ充放電の効率を維持することができる。   In addition, if the electrical equipment is an air conditioner, when the outside air temperature drops and the temperature drops to a temperature unsuitable for charging or discharging the storage battery, the exhaust temperature from the outdoor unit is guided to the surroundings of the storage battery to increase the ambient temperature, thereby improving the efficiency of charging and discharging Can be maintained.

このように電気機器と蓄電池とで協調制御することは、電力供給手段２３から電気機器の制御手段１９、第一の充電手段１６、第二の充電手段３０を統合制御することで可能である。   Thus, cooperative control between the electric device and the storage battery is possible by performing integrated control of the electric device control unit 19, the first charging unit 16, and the second charging unit 30 from the power supply unit 23.

なお、充電手段付き電気機器を、電気機器付き充電手段（充電手段をメインとして、それに電気機器の機能を付加させたもの）として実現してもよい。   In addition, you may implement | achieve the electric equipment with a charging means as a charging means with an electric equipment (The thing which made the charging means the main and added the function of the electric equipment to it).

以上のように本発明によると、家庭や事務所、工場などにおいて屋外に少なくとも一部が設置される電気機器を利用して、電気機器の運転と電動車両の充電との統合制御が容易になる。また電動車両に代えて、屋外や倉庫などに固定設置される蓄電池についても、電気機器の運転と蓄電池の充電との統合制御が容易になる。   As described above, according to the present invention, the integrated control of the operation of the electric device and the charging of the electric vehicle is facilitated by using the electric device that is at least partially installed outdoors in a home, office, factory, or the like. . Further, instead of an electric vehicle, for a storage battery fixedly installed outdoors or in a warehouse, the integrated control of the operation of the electric device and the charging of the storage battery becomes easy.

充電手段付き電気機器は利用者認識装置や自動精算機、自動販売機などを含めて、屋外に設置される電気機器で実現可能である。   The electric device with a charging means can be realized by an electric device installed outdoors, including a user recognition device, an automatic payment machine, and a vending machine.
