Description

本発明は、車両用電力システムに関するものである。 The present invention relates to a vehicle power system.

特許文献1には、走行中に所定の区間において車両外部のエネルギ供給装置から非接触の方法を用いて送られたエネルギの供給を受ける車両が開示されている。特許文献1に開示された車両は、エネルギ供給装置からエネルギを受けるエネルギ受取部と、エネルギ供給装置に関する情報を取得するための通信部と、車両の状態に応じて、外部から供給を受けるエネルギの目標量を決定し、通信部を介して得た情報に基づいて、目標量のエネルギを受取るために所定の区間に滞在する時間に関するパラメータを算出する制御部とを備えている。 Patent Document 1 discloses a vehicle that receives energy supplied from an energy supply device outside the vehicle in a predetermined section while traveling by a non-contact method.

国際公開第2010/041312号International Publication No. 2010/041312

ところで、例えば特許文献1に開示されるような電気自動車においては、エンジンからの排熱が使えない。このため、空調装置は、電動圧縮機を用いたヒートポンプや、発熱素子等に対して、走行用のバッテリから給電を受けることによって冷暖房を行うことになる。しかしながら、走行用のバッテリを介して、外部電力を空調装置に給電すると、外部充電器とバッテリと間、バッテリとヒータとの間で2回のエネルギ変換を行うため、エネルギ損失が大きい。さらに、バッテリの内部抵抗によるエネルギ損失もあるため、外部から得られる使用可能なエネルギ量が小さくなる。 By the way, in an electric vehicle as disclosed in Patent Document 1, for example, the waste heat from the engine cannot be used. Therefore, the air conditioner heats and cools the heat pump using the electric compressor, the heat generating element, and the like by receiving power from the traveling battery. However, when the external electric power is supplied to the air conditioner via the traveling battery, energy conversion is performed twice between the external charger and the battery and between the battery and the heater, so that the energy loss is large. Further, since there is energy loss due to the internal resistance of the battery, the amount of energy that can be used from the outside is reduced.

本発明は、上述する問題点に鑑みてなされたもので、車両の走行中に車両の外部からバッテリに給電可能な車両用電力システムにおいて、空調の使用時の給電効率を向上させることを目的とする。 The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to improve the power supply efficiency when using air conditioning in a vehicle power system capable of supplying power to a battery from the outside of the vehicle while the vehicle is running. do.

本発明の第1の態様は、上記課題を解決するための手段として、車両の走行あるいは車両の空調に用いる電力を蓄えるバッテリを備え、車両の走行中に車両の外部から上記バッテリに給電可能な車両用電力システムにおいて、上記外部から非接触にて受電する非接触受電部と、上記非接触受電部から出力される交流電力を直流電力に変換するコンバータと、上記コンバータから出力される電力の供給先を上記バッテリと蓄熱デバイス及び熱生成デバイスを有して上記空調を行う空調デバイスとに切り替え可能な切替器と、上記切替器を制御する制御部とを備え、上記制御部が、上記バッテリの充電量が充電閾値以上であり、上記空調デバイスの予想消費電力が消費電力閾値以上であり、上記蓄熱デバイスの蓄熱量が蓄熱閾値以下である場合には、上記空調デバイスを上記電力の供給先とし、上記バッテリの充電量が上記充電閾値より低い場合には、上記バッテリを上記電力の供給先として上記蓄熱デバイスの蓄熱によって上記空調デバイスに空調を続行させるという構成を採用する。 The first aspect of the present invention is provided with a battery for storing electric power used for traveling the vehicle or air conditioning the vehicle as a means for solving the above-mentioned problems, and can supply power to the battery from the outside of the vehicle while the vehicle is traveling. In a vehicle power system, a non-contact power receiving unit that receives power from the outside in a non-contact manner, a converter that converts AC power output from the non-contact power receiving unit into DC power, and supply of power output from the converter. The destination is provided with a switch capable of switching between the battery, the heat storage device, and the air conditioning device having the heat generation device and performing the air conditioning, and the control unit for controlling the switch, and the control unit is the battery. When the charge amount is equal to or more than the charge threshold, the expected power consumption of the air conditioning device is equal to or greater than the power consumption threshold, and the heat storage amount of the heat storage device is equal to or less than the heat storage threshold, the air conditioning device is used as the power supply destination. When the charge amount of the battery is lower than the charge threshold value, a configuration is adopted in which the air conditioner device continues air conditioning by storing heat of the heat storage device using the battery as a power supply destination.

本発明によれば、バッテリの充電量が予め設定された充電閾値を超えて充分量である場合には、バッテリを介することなく、コンバータから出力された電力を空調デバイスに直接供給することができる。したがって、本発明によれば、車両の走行中に車両の外部からバッテリに給電可能な車両用電力システムにおいて、空調装置の使用時の給電効率を向上させることが可能となる。 According to the present invention, when the charge amount of the battery exceeds a preset charge threshold value and is a sufficient amount, the electric power output from the converter can be directly supplied to the air conditioning device without going through the battery. .. Therefore, according to the present invention, it is possible to improve the power supply efficiency when the air conditioner is used in the vehicle power system capable of supplying power to the battery from the outside of the vehicle while the vehicle is running.

以下、図面を参照して、本発明に係る車両用電力システムの一実施形態について説明する。 Hereinafter, an embodiment of the vehicle electric power system according to the present invention will be described with reference to the drawings.

図1は、本実施形態の車両用電力システムの概略構成を示すブロック図である。本実施形態の車両用電力システム1は、車両に搭載され、走行中の車両にて非接触にて供給された電力の供給先をバッテリと空調デバイスとに切り替え可能なシステムである。図1に示すように、車両用電力システム1は、受電コイル2(非接触受電部)と、コンバータ3と、切替器4と、駆動バッテリ5(バッテリ)と、空調デバイス6と、空調制御装置7と、空調装置操作パネル8と、温度センサ9と、制御部10とを備えている。 FIG. 1 is a block diagram showing a schematic configuration of a vehicle electric power system according to the present embodiment. The vehicle electric power system 1 of the present embodiment is a system mounted on a vehicle and capable of switching the supply destination of the electric power non-contactly supplied by the moving vehicle between a battery and an air conditioning device. As shown in FIG. 1, the vehicle power system 1 includes a power receiving coil 2 (non-contact power receiving unit), a converter 3, a switch 4, a drive battery 5 (battery), an air conditioning device 6, and an air conditioning control device. 7, an air conditioner operation panel 8, a temperature sensor 9, and a control unit 10.

受電コイル2は、例えば道路等に埋設配置された外部の送電コイルから非接触にて給電を受けるためのコイルである。この受電コイル2は、例えば車両の底部に配置されており、車両走行中において外部の送電コイルと対向配置された期間において送電コイルから給電される。 The power receiving coil 2 is a coil for receiving power supply in a non-contact manner from, for example, an external power transmission coil embedded in a road or the like. The power receiving coil 2 is arranged at the bottom of the vehicle, for example, and is supplied with power from the power transmission coil during a period in which the power receiving coil 2 is arranged to face the external power transmission coil while the vehicle is traveling.

コンバータ3は、交流電力を直流電力に変換するAC/DCコンバータであり、受電コイル2と接続されている。このコンバータ3は、受電コイル2から出力される交流電力を直流電力に変換する。切替器4は、コンバータ3の出力端子と接続されており、コンバータ3から出力される直流電力の供給先を駆動バッテリ5と空調デバイス6とに切り替えることを可能にしている。 The converter 3 is an AC / DC converter that converts AC power into DC power, and is connected to the power receiving coil 2. The converter 3 converts the AC power output from the power receiving coil 2 into DC power. The switch 4 is connected to the output terminal of the converter 3 and makes it possible to switch the supply destination of the DC power output from the converter 3 between the drive battery 5 and the air conditioning device 6.

駆動バッテリ5は、切替器4を介してコンバータ3と接続されており、切替器4によって直流電力の供給先が駆動バッテリ5に設定されている場合には、外部からの電力が供給される。この駆動バッテリ5は、車両の走行のための電力を蓄えるバッテリであり、不図示のパワーコントロールユニットを介してモータと接続されている。また、駆動バッテリ5の電力は、不図示のスイッチ等によって空調デバイス6にも供給可能とされている。つまり、駆動バッテリ5は、車両の走行あるいは車両の空調に用いる電力を蓄えている。 The drive battery 5 is connected to the converter 3 via the switch 4, and when the DC power supply destination is set to the drive battery 5 by the switch 4, power from the outside is supplied. The drive battery 5 is a battery that stores electric power for traveling of a vehicle, and is connected to a motor via a power control unit (not shown). Further, the electric power of the drive battery 5 can be supplied to the air conditioning device 6 by a switch or the like (not shown). That is, the drive battery 5 stores electric power used for traveling the vehicle or air-conditioning the vehicle.

空調デバイス6は、切替器4を介してコンバータ3と接続されており、切替器4によって直流電力の供給先が駆動バッテリ5に設定されている場合には、外部からの電力が供給される。この空調デバイス6は、電力を用いて温熱あるいは冷熱を生成する熱生成デバイス6aと、電力を用いて生成した温熱あるいは冷熱を蓄熱する蓄熱デバイス6bとを備えている。空調デバイス6は、これらの熱生成デバイス6aと蓄熱デバイス6bとを用いて温度及び湿度が調整された調和空気を生成して車室内に供給する。 The air conditioning device 6 is connected to the converter 3 via the switch 4, and when the DC power supply destination is set to the drive battery 5 by the switch 4, the power from the outside is supplied. The air conditioning device 6 includes a heat generation device 6a that generates heat or cold heat using electric power, and a heat storage device 6b that stores heat or cold heat generated using electric power. The air-conditioning device 6 uses these heat generation devices 6a and heat storage devices 6b to generate harmonious air whose temperature and humidity are adjusted and supplies it to the vehicle interior.

なお、空調デバイスには、熱生成デバイス6aとして、例えば気化熱によって冷熱を生成する冷媒を圧縮する電動圧縮機や、熱抵抗によって温熱を得る発熱ヒータ等が、単数あるいは複数設けられている。 The air conditioning device is provided with one or a plurality of heat generation devices 6a, for example, an electric compressor that compresses a refrigerant that generates cold heat by vaporization heat, a heat generating heater that obtains heat by thermal resistance, and the like.

空調制御装置7は、空調デバイス6と接続されており、例えば空調装置操作パネル8で設定された温度に車室内が調整されるように空調デバイス6を制御する。空調装置操作パネル8は、マンマシンインターフェイスであり、車両の乗員が温度設定等のために操作する操作部である。温度センサ9は、車室内の温度を計測し、計測結果を出力する。温度センサ9の計測結果は、本実施形態においては、空調制御装置7及び制御部10に入力される。 The air-conditioning control device 7 is connected to the air-conditioning device 6, and controls the air-conditioning device 6 so that the interior of the vehicle is adjusted to the temperature set by the air-conditioning device operation panel 8, for example. The air conditioner operation panel 8 is a man-machine interface, and is an operation unit operated by a vehicle occupant for temperature setting and the like. The temperature sensor 9 measures the temperature inside the vehicle and outputs the measurement result. The measurement result of the temperature sensor 9 is input to the air conditioning control device 7 and the control unit 10 in the present embodiment.

制御部10は、本実施形態の車両用電力システムの全体を制御する装置である。この制御部10は、切替器4、駆動バッテリ5、空調制御装置7及び温度センサ9等と電気的に接続されている。 The control unit 10 is a device that controls the entire vehicle power system of the present embodiment. The control unit 10 is electrically connected to a switch 4, a drive battery 5, an air conditioning control device 7, a temperature sensor 9, and the like.

本実施形態において制御部10は、駆動バッテリ5の充電量が充電閾値以上であり、空調デバイス6の予想消費電力が消費電力閾値以上であり、蓄熱デバイス6bの蓄熱量が蓄熱閾値以下である場合には、空調デバイス6を外部から給電された電力の供給先とする。また、本実施形態において制御部10は、駆動バッテリ5の充電量が充電閾値より低い場合には、駆動バッテリ5を外部から給電された電力の供給先とし、蓄熱デバイス6bの蓄熱によって空調デバイス6に空調を続行させる。 In the present embodiment, the control unit 10 has a case where the charge amount of the drive battery 5 is equal to or more than the charge threshold, the expected power consumption of the air conditioner device 6 is equal to or more than the power consumption threshold, and the heat storage amount of the heat storage device 6b is equal to or less than the heat storage threshold. The air conditioner device 6 is used as a supply destination of electric power supplied from the outside. Further, in the present embodiment, when the charge amount of the drive battery 5 is lower than the charge threshold value, the control unit 10 uses the drive battery 5 as a supply destination of the power supplied from the outside, and the air conditioning device 6 by the heat storage of the heat storage device 6b. To continue air conditioning.

次に、このように構成された本実施形態の車両用電力システム1の動作について、図2のフローチャートを参照して説明する。なお、以下の説明では、車両用電力システム1において、受電コイル2を介して外部から非接触給電される電力の供給先を判定する動作について説明する。 Next, the operation of the vehicle power system 1 of the present embodiment configured as described above will be described with reference to the flowchart of FIG. In the following description, in the vehicle power system 1, the operation of determining the supply destination of the power to be non-contactly fed from the outside via the power receiving coil 2 will be described.

まず制御部10は、空調デバイス6の電源がオン状態であることを確認する(ステップS1)。空調デバイス6の電源がオン状態である場合には、続いて制御部10は、駆動バッテリ5の充電量が充電閾値以上であるか否かの判定を行う(ステップS2)。例えば、充電量としてはSOC(State of Charge)が用いられ、充電閾値としては20%が用いられる。この例では、制御部10は、駆動バッテリ5のSOCが20%以上であるか否かの判定がステップS2で行われる。 First, the control unit 10 confirms that the power of the air conditioning device 6 is on (step S1). When the power of the air conditioning device 6 is on, the control unit 10 subsequently determines whether or not the charge amount of the drive battery 5 is equal to or greater than the charge threshold value (step S2). For example, SOC (State of Charge) is used as the charge amount, and 20% is used as the charge threshold. In this example, the control unit 10 determines in step S2 whether or not the SOC of the drive battery 5 is 20% or more.

ステップS2において駆動バッテリ5の充電量が充電閾値以上である場合には、制御部10は、空調デバイス6の予想消費電力が消費電力閾値以上であるか否かの判定を行う(ステップS3)。乗員によって設定された車室温度と車室内の温度との差が大きい場合には空調デバイス6の消費電力が大きい。このため、例えば制御部10は、設定された車室温度と車室内の温度との差から予想消費電力を算出し、この予想消費電力が予め記憶した消費電力閾値以上であるか否かを判定する。 When the charge amount of the drive battery 5 is equal to or greater than the charge threshold value in step S2, the control unit 10 determines whether or not the expected power consumption of the air conditioning device 6 is equal to or greater than the power consumption threshold value (step S3). When the difference between the vehicle interior temperature set by the occupant and the vehicle interior temperature is large, the power consumption of the air conditioning device 6 is large. Therefore, for example, the control unit 10 calculates the expected power consumption from the difference between the set vehicle interior temperature and the vehicle interior temperature, and determines whether or not the estimated power consumption is equal to or higher than the power consumption threshold stored in advance. do.

ステップS3で空調デバイス6の予想消費電力が消費電力閾値以上である場合(すなわち空調デバイス6の消費電力が大きいと判断される場合)には、続いて制御部10は、蓄熱デバイス6bの蓄熱量が蓄熱閾値以下であるか否かの判定を行う(ステップS4)。 When the expected power consumption of the air conditioning device 6 is equal to or greater than the power consumption threshold in step S3 (that is, when it is determined that the power consumption of the air conditioning device 6 is large), the control unit 10 subsequently determines the heat storage amount of the heat storage device 6b. Determines whether or not is equal to or less than the heat storage threshold (step S4).

制御部10は、ステップS4にて蓄熱デバイス6bの蓄熱量が蓄熱閾値以下であると判定した場合には、非接触給電により供給される電力の供給先を空調デバイス6とし(ステップS5)、切替器4を制御する。 When the control unit 10 determines in step S4 that the heat storage amount of the heat storage device 6b is equal to or less than the heat storage threshold value, the control unit 10 sets the supply destination of the power supplied by the non-contact power supply to the air conditioning device 6 (step S5) and switches. Control the vessel 4.

一方で、ステップS1で空調デバイス6の電源がオン状態でない場合、ステップS3で空調デバイス6の予想消費電力が消費電力閾値以上でない場合、及び、ステップS4で蓄熱デバイス6bの蓄熱量が蓄熱閾値以下でない場合には、制御部10は、駆動バッテリ5が満充電であるか否かの判定を行う(ステップS6)。ここで、駆動バッテリ5が満充電である場合には、制御部10は、充電を行わないと判断する(ステップS7)。 On the other hand, when the power of the air conditioner device 6 is not turned on in step S1, the expected power consumption of the air conditioner device 6 is not equal to or more than the power consumption threshold in step S3, and the heat storage amount of the heat storage device 6b is equal to or less than the heat storage threshold in step S4. If not, the control unit 10 determines whether or not the drive battery 5 is fully charged (step S6). Here, when the drive battery 5 is fully charged, the control unit 10 determines that charging is not performed (step S7).

また、ステップS2で駆動バッテリ5の充電量が充電閾値以上でない場合には、制御部10は、空調制御装置7に熱生成デバイス6aを停止させると共に蓄熱デバイス6bの蓄熱によって空調を続行させる(ステップS8)。ステップS8の後、制御部10は、非接触給電により供給される電力の供給先を駆動バッテリ5とし(ステップS9)、切替器4を制御する。なお、ステップS6で駆動バッテリ5が満充電でないと判定した場合も、制御部10は、非接触給電により供給される電力の供給先を駆動バッテリ5とする(ステップS9)。 If the charge amount of the drive battery 5 is not equal to or more than the charge threshold value in step S2, the control unit 10 causes the air conditioning control device 7 to stop the heat generation device 6a and continue air conditioning by storing heat in the heat storage device 6b (step). S8). After step S8, the control unit 10 controls the switch 4 by setting the supply destination of the electric power supplied by the non-contact power supply to the drive battery 5 (step S9). Even if it is determined in step S6 that the drive battery 5 is not fully charged, the control unit 10 sets the supply destination of the power supplied by the non-contact power supply to the drive battery 5 (step S9).

以上のような本実施形態の車両用電力システム1は、車両の走行あるいは車両の空調に用いる電力を蓄える駆動バッテリ5を備え、車両の走行中に車両の外部から駆動バッテリ5に給電が可能である。また、本実施形態の車両用電力システム1は、外部から非接触にて受電する受電コイル2と、受電コイル2から出力される交流電力を直流電力に変換するコンバータ3と、コンバータ3から出力される電力の供給先を駆動バッテリ5と蓄熱デバイス6b及び熱生成デバイス6aを有して空調を行う空調デバイス6とに切り替え可能な切替器4と、切替器4を制御する制御部10とを備えている。また、制御部10は、駆動バッテリ5の充電量が充電閾値以上であり、空調デバイス6の予想消費電力が消費電力閾値以上であり、蓄熱デバイス6bの蓄熱量が蓄熱閾値以下である場合には、空調デバイス6を電力の供給先とし、駆動バッテリ5の充電量が充電閾値より低い場合には、駆動バッテリ5を電力の供給先として蓄熱デバイス6bの蓄熱によって空調デバイス6に空調を続行させる。 The vehicle electric power system 1 of the present embodiment as described above includes a drive battery 5 for storing electric power used for traveling the vehicle or air-conditioning the vehicle, and can supply power to the drive battery 5 from the outside of the vehicle while the vehicle is traveling. be. Further, the vehicle power system 1 of the present embodiment is output from a power receiving coil 2 that receives power from the outside in a non-contact manner, a converter 3 that converts AC power output from the power receiving coil 2 into DC power, and a converter 3. The electric power supply destination is provided with a switch 4 capable of switching between a drive battery 5, a heat storage device 6b, and an air conditioning device 6 having a heat generation device 6a for air conditioning, and a control unit 10 for controlling the switch 4. ing. Further, in the control unit 10, when the charge amount of the drive battery 5 is equal to or more than the charge threshold, the expected power consumption of the air conditioning device 6 is equal to or more than the power consumption threshold, and the heat storage amount of the heat storage device 6b is equal to or less than the heat storage threshold. When the charge amount of the drive battery 5 is lower than the charging threshold, the air conditioner device 6 is made to continue air conditioning by the heat storage of the heat storage device 6b with the drive battery 5 as the power supply destination.

本実施形態の車両用電力システム1によれば、駆動バッテリ5の充電量が予め設定された充電閾値を超えて充分量である場合には、駆動バッテリ5を介することなく、コンバータ3から出力された電力を空調デバイス6に直接供給することができる。したがって、本実施形態の車両用電力システム1によれば、車両の走行中に車両の外部から駆動バッテリ5に給電可能な車両用電力システムにおいて、空調の使用時の給電効率を向上させることが可能となる。 According to the vehicle power system 1 of the present embodiment, when the charge amount of the drive battery 5 exceeds a preset charge threshold and is a sufficient amount, it is output from the converter 3 without going through the drive battery 5.
