Description

本発明は、家庭用電源から供給される電力により蓄電される蓄電装置を備えた車両に関する。   The present invention relates to a vehicle including a power storage device that is charged with electric power supplied from a household power source.

近年、内燃機関及び蓄電装置を動力源として兼用するハイブリッド車両、蓄電装置のみを動力源とする電動車両などの開発が活発に行われている。蓄電装置には、回生制動時に発電された電力、車両に搭載された発電機が発電した電力が蓄えられる。   2. Description of the Related Art In recent years, development of hybrid vehicles that use an internal combustion engine and a power storage device as a power source, and electric vehicles that use only a power storage device as a power source has been actively conducted. The power storage device stores electric power generated during regenerative braking and electric power generated by a generator mounted on the vehicle.

それに加えて、近年、例えば家屋などに備え付けられた外部電源を用いて、車両の蓄電装置を充電するいわゆるプラグイン車両が提案されている。家屋に設けられたコンセントと、車両に設けられたコネクタとをケーブルで電気的に接続することにより、外部電源から車両に搭載された蓄電装置に電力を供給して充電を行うことができる。   In addition, in recent years, a so-called plug-in vehicle has been proposed in which a power storage device of a vehicle is charged using, for example, an external power source provided in a house or the like. By electrically connecting an outlet provided in the house and a connector provided in the vehicle with a cable, electric power can be supplied from an external power source to the power storage device mounted on the vehicle for charging.

しかしながら、蓄電装置の充電中に、種々の要因で外部電源から蓄電装置への電力の供給が絶たれる場合がある。例えば、蓄電装置の充電中にエアコン等を使用することにより消費電力が増加して、家庭用電源のブレーカが遮断される場合がある。その結果、電気製品のタイマーがオフになり、ユーザが予め設定した時間に炊飯器、エアコン、録画装置が作動しないなどの不具合が起こる。   However, during charging of the power storage device, power supply from the external power source to the power storage device may be interrupted due to various factors. For example, the use of an air conditioner or the like during charging of the power storage device may increase power consumption and shut off the breaker of the household power source. As a result, the timer of the electric product is turned off, and problems such as the rice cooker, the air conditioner, and the recording device not operating at the time set in advance by the user occur.

そこで、本発明は、車両に搭載された蓄電装置を充電する家庭用電源からの電力の供給が絶たれた際に、この電力の供給が絶たれたことをユーザに報知することを目的とする。   Therefore, the present invention has an object of notifying the user that the supply of electric power has been cut off when the supply of electric power from a household power supply for charging a power storage device mounted on the vehicle is cut off. .

上記課題を解決するために本発明の車両は、車両外部の家庭用電源からの電力供給を受けて充電可能であるとともに、車両の走行に用いられるエネルギを出力する蓄電装置と、家庭内の配電系統の異常によって家庭用電源から蓄電装置への電力供給が絶たれたときに、この電力供給が絶たれたことを示す信号を車両外部の外部端末に送信する通信部と、を有する。   In order to solve the above-described problems, a vehicle according to the present invention can be charged by receiving power from a household power supply outside the vehicle, and can store a power storage device that outputs energy used for running the vehicle, and power distribution in the home. And a communication unit that transmits a signal indicating that the power supply is cut off to an external terminal outside the vehicle when the power supply from the household power supply to the power storage device is cut off due to a system abnormality.

ここで、家庭用電源から蓄電装置への電力供給の有無を検知する検知部を、車両に搭載しておくことができる。また、検知部として、家庭用電源の電力を蓄電装置に充電する充電器に設けられた電圧センサを用いることができる。これにより、簡易な方法で充電が中断したことを検知することができる。   Here, a detection unit that detects whether power is supplied from the household power supply to the power storage device can be mounted on the vehicle. Further, as the detection unit, a voltage sensor provided in a charger that charges the power storage device with electric power from a household power source can be used. Thereby, it is possible to detect that charging has been interrupted by a simple method.

通信部は、車両の位置情報を通信により取得するナビゲーションシステムにも用いることができる。これにより、蓄電装置の充電が中断したことを報知する通信機能を新たに追加する必要がなくなり、コストアップを抑制することができる。   The communication unit can also be used in a navigation system that acquires vehicle position information through communication. Thereby, it is not necessary to newly add a communication function for notifying that the charging of the power storage device has been interrupted, and an increase in cost can be suppressed.

外部端末としては、携帯情報端末を用いることができる。これにより、携帯情報端末の所有者（言い換えれば、本発明の車両の所有者）に対して、蓄電装置の充電が中断したことを、より確実に報知することができる。   A portable information terminal can be used as the external terminal. Thereby, it is possible to more reliably notify the owner of the portable information terminal (in other words, the owner of the vehicle of the present invention) that the charging of the power storage device has been interrupted.

本発明によれば、車両の通信機能を用いて、家庭用電源から蓄電装置への電力の供給が絶たれたことをユーザに報知することができる。   ADVANTAGE OF THE INVENTION According to this invention, it can alert | report to a user that the supply of the electric power from a household power supply to an electrical storage apparatus was cut | disconnected using the communication function of a vehicle.

車両のブロック図である。It is a block diagram of a vehicle. 車両と携帯電話とが通信する通信システムの概略図である。1 is a schematic diagram of a communication system in which a vehicle and a mobile phone communicate.

図１は、車両のブロック図であり、図２は、車両と携帯電話とが通信する通信システムの概略図である。図１を参照して、本発明の実施例である車両の構成について説明する。本実施例の車両は、蓄電装置により駆動されるモータと内燃機関とを動力源として兼用するハイブリッド車両である。   FIG. 1 is a block diagram of a vehicle, and FIG. 2 is a schematic diagram of a communication system in which the vehicle and a mobile phone communicate. With reference to FIG. 1, the structure of the vehicle which is an Example of this invention is demonstrated. The vehicle of the present embodiment is a hybrid vehicle that uses both a motor driven by a power storage device and an internal combustion engine as power sources.

図１を参照して、ハイブリッド車両１は、エンジン１０、モータ・ジェネレータとしての機能を有するＭＧ２０、インバータ３０、コンバータ４０、蓄電装置５０、充電器６０、コントローラ７０を含む。   Referring to FIG. 1, hybrid vehicle 1 includes an engine 10, an MG 20 having a function as a motor / generator, an inverter 30, a converter 40, a power storage device 50, a charger 60, and a controller 70.

ハイブリッド車両１は、エンジン１０及びＭＧ２０のうち少なくとも一方からの駆動力により走行する。ＭＧ２０は、三相交流モータであり、蓄電装置５０から供給される電力により駆動される。ＭＧ２０には、インバータ３０により直流から交流に変換された電力が供給される。ＭＧ２０で発生した駆動力は、エンジン１０をアシストして車両を走行させたり、その駆動力のみで車両を走行させたりする。   Hybrid vehicle 1 travels by driving force from at least one of engine 10 and MG 20. MG 20 is a three-phase AC motor, and is driven by electric power supplied from power storage device 50. The MG 20 is supplied with power converted from direct current to alternating current by the inverter 30. The driving force generated by the MG 20 assists the engine 10 to drive the vehicle, or causes the vehicle to run only by the driving force.

ハイブリッド車両１の回生制動時には、車輪によりＭＧ２０が駆動されることにより、ＭＧ２０が発電機として作動する。これによりＭＧ２０は、制動エネルギを電力に変換する回生ブレーキとして作用する。ＭＧ２０により発電された電力は、インバータ３０により交流から直流に変換された後、蓄電装置５０に蓄電（充電）される。   At the time of regenerative braking of the hybrid vehicle 1, the MG 20 operates as a generator by being driven by the wheels. Thereby, MG20 acts as a regenerative brake which converts braking energy into electric power. The electric power generated by the MG 20 is converted from alternating current to direct current by the inverter 30 and then stored (charged) in the power storage device 50.

蓄電装置５０は、複数の単電池を電気的に直列に接続することにより構成されている。なお、電気的に並列に接続された単電池が含まれていてもよい。各単電池には、リチウムイオン電池やニッケル水素電池といった二次電池を用いることができる。また、二次電池の代わりに、電気二重層キャパシタ（コンデンサ）を用いることができる。蓄電装置５０からの放電電圧及び蓄電装置５０への充電電圧は、コンバータ４０により調整される。蓄電装置５０の総プラス端子及び総マイナス端子には、充電器６０が接続される。   The power storage device 50 is configured by electrically connecting a plurality of single cells in series. In addition, the single battery electrically connected in parallel may be included. For each single battery, a secondary battery such as a lithium ion battery or a nickel metal hydride battery can be used. An electric double layer capacitor (capacitor) can be used instead of the secondary battery. The discharge voltage from power storage device 50 and the charging voltage to power storage device 50 are adjusted by converter 40. A charger 60 is connected to the total positive terminal and the total negative terminal of the power storage device 50.

充電器６０は、蓄電装置５０に供給する電力の電圧および電流を制御する。充電器６０から蓄電装置５０には、直流電流が供給される。すなわち、充電器６０は、交流電流を直流電流に変換する。また、充電器６０は、電圧を昇圧する。   Charger 60 controls the voltage and current of power supplied to power storage device 50. A direct current is supplied from the charger 60 to the power storage device 50. That is, the charger 60 converts alternating current into direct current. The charger 60 boosts the voltage.

充電器６０の内部には、電圧センサ（検出部）６１が設けられている。電圧センサ６１により検出された電圧値に対応した信号はコントローラ７０に送信される。この電圧センサ６１により、外部電源８０から蓄電装置５０への電力の供給の有無を検知することができる。   A voltage sensor (detection unit) 61 is provided inside the charger 60. A signal corresponding to the voltage value detected by the voltage sensor 61 is transmitted to the controller 70. With this voltage sensor 61, it is possible to detect whether or not power is supplied from the external power supply 80 to the power storage device 50.

充電器６０は、インレット６４を介して充電ケーブル１００に接続されている。充電ケーブル１００は、外部電源８０のプラグ８１に接続される。外部電源８０には、家庭、電気スタンドに備え付けられた電源を用いることができる。   The charger 60 is connected to the charging cable 100 via the inlet 64. Charging cable 100 is connected to plug 81 of external power supply 80. As the external power source 80, a power source provided in a home or a desk lamp can be used.

次に、ハイブリッド車両１に搭載された通信機能について説明する。図２を参照して、ハイブリッド車両１に用いられる通信システムは、サーバ２１が設置された情報センター２と、携帯端末（外部端末）４及び車載端末（通信部）３１とが、双方向通信可能なインターネット回線を介して互いに接続されて構成されている。   Next, the communication function mounted on the hybrid vehicle 1 will be described. Referring to FIG. 2, in the communication system used in hybrid vehicle 1, information center 2 in which server 21 is installed, portable terminal (external terminal) 4, and in-vehicle terminal (communication unit) 31 can communicate bidirectionally. Connected to each other via a simple internet line.

情報センター２は、サーバ２１及びデータベース（ＤＢ）２２を含む。このＤＢ２２には、地図情報などが格納されている。サーバ２１は、必要に応じて、ＤＢ２２にアクセスして所定の情報を読み出すことができる。携帯端末４には、ハイブリッド車両１の所有者若しくはその家族などが所有する携帯電話などのＰＤＡ（Personal Digital Assistant:携帯情報端末）を用いることができる。車載端末３１は、ハイブリッド車両１に搭載されており、車両の経路誘導を行ういわゆるナビゲーション装置としての機能を有する。   The information center 2 includes a server 21 and a database (DB) 22. This DB 22 stores map information and the like. The server 21 can read the predetermined information by accessing the DB 22 as necessary. As the portable terminal 4, a PDA (Personal Digital Assistant: portable information terminal) such as a cellular phone owned by the owner of the hybrid vehicle 1 or its family can be used. The in-vehicle terminal 31 is mounted on the hybrid vehicle 1 and has a function as a so-called navigation device that performs route guidance of the vehicle.

車載端末３１は、情報センター２を介して、外部電源８０から蓄電装置５０への電力の供給が絶たれたことを携帯端末４に送信する機能を有している。送信方法としては、電子メールを用いることができる。また、ＤＢ２２には、ハイブリッド車両１と携帯端末４とを対応付ける対応情報が格納されている。   The in-vehicle terminal 31 has a function of transmitting to the portable terminal 4 that the supply of power from the external power supply 80 to the power storage device 50 is cut off via the information center 2. As a transmission method, electronic mail can be used. The DB 22 stores correspondence information that associates the hybrid vehicle 1 with the mobile terminal 4.

次に、蓄電装置５０の充電が中断した際のハイブリッド車両１の動作について詳細に説明する。なお、初期状態において、ハイブリッド車両１に搭載された蓄電装置５０は、外部電源８０に接続されることにより充電されているものとする。   Next, the operation of hybrid vehicle 1 when charging of power storage device 50 is interrupted will be described in detail. In the initial state, it is assumed that power storage device 50 mounted on hybrid vehicle 1 is charged by being connected to external power supply 80.

外部電源８０から蓄電装置５０への電力の供給が絶たれると、充電器６０の電圧センサ６１により検出される電圧値が０に変化する。ここで、外部電源８０から蓄電装置５０への電力の供給が絶たれる場合として、家庭内消費電力の増大に伴うブレーカによる電流遮断、電力会社から外部電源８０への電力供給の遮断などが想定される。本実施例では、ブレーカの作動による電流遮断といった、家庭内における配電系統の異常によって、外部電源８０から蓄電装置５０への電力供給が絶たれた場合を想定している。   When the supply of power from the external power supply 80 to the power storage device 50 is cut off, the voltage value detected by the voltage sensor 61 of the charger 60 changes to zero. Here, as the case where the power supply from the external power source 80 to the power storage device 50 is cut off, it is assumed that the current is interrupted by a breaker due to an increase in household power consumption, the power supply from the power company to the external power source 80 is interrupted, and the like. The In the present embodiment, it is assumed that the power supply from the external power source 80 to the power storage device 50 is cut off due to an abnormality in the power distribution system in the home such as current interruption due to the operation of the breaker.

コントローラ７０は、電圧センサ６１の電圧値が０になると、電力の供給が絶たれたものと判別し、この判別情報を車載端末３１に送信する。車載端末３１は、この判別情報を受信すると、情報センター２を介してユーザの携帯端末４に電子メールを送信する。ユーザは、この携帯端末４に送信された電子メールの内容を確認することにより、蓄電装置５０の充電が中断したことを認識する。   When the voltage value of the voltage sensor 61 becomes 0, the controller 70 determines that the power supply has been cut off, and transmits this determination information to the in-vehicle terminal 31. When receiving this discrimination information, the in-vehicle terminal 31 transmits an e-mail to the user's portable terminal 4 via the information center 2. The user recognizes that the charging of the power storage device 50 is interrupted by checking the content of the e-mail transmitted to the mobile terminal 4.

このように本実施例によれば、ハイブリッド車両１に搭載された通信機能を用いた簡易な方法で、蓄電装置５０の充電が中断したことをユーザに報知することができる。これにより、ユーザは、例えば、蓄電装置５０の充電を禁止してブレーカを復帰させる、家庭内の電化製品をオフにした状態でブレーカを復帰させる等の事後処理を行うことができる。   As described above, according to the present embodiment, it is possible to notify the user that the charging of the power storage device 50 is interrupted by a simple method using the communication function mounted on the hybrid vehicle 1. Accordingly, the user can perform post-processing such as, for example, prohibiting charging of the power storage device 50 and returning the breaker, or returning the breaker with the household appliances turned off.

また、充電の中断を報知するために、新たな通信機器を設ける必要がないため、コストを削減することができる。   Moreover, since it is not necessary to provide a new communication apparatus in order to alert | report interruption of charge, cost can be reduced.

さらに、ユーザの携帯端末４に情報を送信することにより、充電が中断したことをより確実にユーザに報知することができる。   Furthermore, by transmitting information to the user's portable terminal 4, it is possible to more reliably notify the user that charging has been interrupted.
