本発明の一実施形態に係るバッテリ温調装置の構成を示すブロック図である。It is a block diagram showing composition of a battery temperature control device concerning one embodiment of the present invention.

以下、図面を参照して、本発明の一実施形態について説明する。
本実施形態に係るバッテリ温調装置は、車両に備えられるバッテリ及び車室を温度調節する装置であり、図１に示すように遠心ファンである。第１送風機１、第２送風機２、冷却器３、加熱器４、第３送風機５及びこれらを並列した２系統として相互接続する空気流路から形成されている。また、このバッテリ温調装置は、第１送風機１、第２送風機２、冷却器３、加熱器４及び第３送風機５の動作を制御する制御装置６を備えている。 An embodiment of the present invention will be described below with reference to the drawings.
The battery temperature control device according to the present embodiment is a device that controls the temperature of a battery and a vehicle compartment provided in a vehicle, and is a centrifugal fan as shown in FIG. 1. It is formed of a first blower 1, a second blower 2, a cooler 3, a heater 4, a third blower 5 and an air flow path interconnecting these in two parallel systems. The battery temperature controller also includes a control device 6 that controls the operations of the first blower 1, the second blower 2, the cooler 3, the heater 4, and the third blower 5.

すなわち、第１送風機１、冷却器３及び加熱器４は、第１系統の空気流路によって相互接続されることによって第１流路Ｌ１を形成している。この第１流路Ｌ１は、図示するように車室に空調空気を供給する。また、第２送風機２、冷却器３、加熱器４及び第３送風機５は、第２系統の空気流路によって相互接続されることによって第２流路Ｌ２を形成している。この第２流路Ｌ２は、図示するようにバッテリに空調空気を供給する。 That is, the first blower 1, the cooler 3, and the heater 4 form the first flow path L1 by being interconnected by the air flow path of the first system. The first flow path L1 supplies conditioned air to the vehicle compartment as shown. Further, the second blower 2, the cooler 3, the heater 4, and the third blower 5 form a second flow path L2 by being interconnected by the air flow path of the second system. The second flow path L2 supplies conditioned air to the battery as shown.

第１送風機１は、外気あるいは車室空気を取り込んで冷風機に向けて排出する遠心ファンである。第２送風機２は、上記第１送風機１とは別系統として設けられており、第１送風機１と同様に外気あるいは車室空気を取り込んで冷風機３に向けて排出する遠心ファンである。なお、このような第１送風機１と第２送風機２とは、冷風機３の異なる領域、例えば第１送風機１は冷風機３の第１領域に向けて外気あるいは車室空気を排出し、第２送風機２は冷風機３の第２領域に向けて外気あるいは車室空気を排出する。 The first blower 1 is a centrifugal fan that takes in outside air or vehicle compartment air and discharges it toward a cool air blower. The second blower 2 is provided as a separate system from the first blower 1 and is a centrifugal fan that takes in outside air or vehicle compartment air and discharges it toward the cool air blower 3 like the first blower 1. The first blower 1 and the second blower 2 as described above are different from each other in the cooler fan 3, for example, the first blower 1 discharges the outside air or the cabin air toward the first region of the cooler fan 3, The 2 blower 2 discharges outside air or vehicle compartment air toward the second region of the cool air blower 3.

冷却器３は、第１送風機１から第１領域に送り込まれた外気あるいは車室空気を冷却し、第１空気として加熱器４の第１領域に向かって通過させる。また、この冷却器３は、第２送風機２から第２領域に送り込まれた外気あるいは車室空気を冷却し、第２空気として加熱器４の第２領域に向かって通過させる。 The cooler 3 cools the outside air or the cabin air sent from the first blower 1 to the first area, and passes it as the first air toward the first area of the heater 4. Further, the cooler 3 cools the outside air or the cabin air sent from the second blower 2 to the second region, and passes it as the second air toward the second region of the heater 4.

加熱器４は、上記冷却器３から第１領域に送り込まれた第１空気を加熱し第１空調空気として車室に向けて排出する。また、この加熱器４は、上記冷却器３から第２領域に送り込まれた第２空気を加熱し第２空調空気として第３送風機５に向けて排出する。すなわち、第１空調空気及び第２空調空気は、外気あるいは車室空気が冷却器３及び加熱器４を通過することによって所望温度に温度調節された温調空気である。 The heater 4 heats the first air sent to the first region from the cooler 3 and discharges it as first conditioned air toward the passenger compartment. In addition, the heater 4 heats the second air sent from the cooler 3 to the second region and discharges it as second conditioned air toward the third blower 5. That is, the first conditioned air and the second conditioned air are temperature-controlled air whose temperature is adjusted to a desired temperature by the outside air or the cabin air passing through the cooler 3 and the heater 4.

第３送風機５は、上記第２空調空気をバッテリに向けて送り出す遠心ファンである。第１送風機１、第２送風機２、冷却器３及び加熱器４は、車両において車室に比較的近い場所、例えば車両前部に設けられているが、バッテリは第１送風機１、第２送風機２、冷却器３及び加熱器４から比較的離間した場所、例えば車両後部に設けられている。すなわち、第３送風機５は、バッテリに第２空調空気を供給するために補助的に設けられた空調空気の供給動力源である。 The third blower 5 is a centrifugal fan that blows the second conditioned air toward the battery. The first blower 1, the second blower 2, the cooler 3 and the heater 4 are provided in a place relatively close to the vehicle compartment in the vehicle, for example, in the front part of the vehicle, but the battery is the first blower 1 and the second blower. 2, provided at a place relatively distant from the cooler 3 and the heater 4, for example, at the rear of the vehicle. That is, the third blower 5 is a supply power source of the conditioned air that is auxiliary provided for supplying the second conditioned air to the battery.

制御装置６は、第１送風機１、第２送風機２、冷却器３、加熱器４及び第３送風機５を適宜制御することにより、本実施形態に係るバッテリ温調装置を統一的に作動させる。この制御装置６は、第１送風機１、第２送風機２、冷却器３、加熱器４及び第３送風機５と通信するインタフェース回路を備えており、例えば所定の制御プログラムに基づいて各種制御信号を生成し、当該各種制御信号をインタフェース回路を介して第１送風機１、第２送風機２、冷却器３、加熱器４及び第３送風機５に出力することにより第１送風機１、第２送風機２、冷却器３、加熱器４及び第３送風機５の動作を制御する。 The control device 6 controls the first blower 1, the second blower 2, the cooler 3, the heater 4, and the third blower 5 as appropriate to uniformly operate the battery temperature control device according to the present embodiment. The control device 6 includes an interface circuit that communicates with the first blower 1, the second blower 2, the cooler 3, the heater 4, and the third blower 5, and, for example, sends various control signals based on a predetermined control program. The first blower 1, the second blower 2, by generating and outputting the various control signals to the first blower 1, the second blower 2, the cooler 3, the heater 4 and the third blower 5 via the interface circuit. The operations of the cooler 3, the heater 4, and the third blower 5 are controlled.

次に、本実施形態に係るバッテリ温調装置の動作について詳しく説明する。 Next, the operation of the battery temperature control device according to this embodiment will be described in detail.

制御装置６は、車室の空調が必要な場合、第１送風機１、冷却器３及び加熱器４を作動させることにより車室に第１空調空気を供給する。この結果、車室は車両の搭乗者にとって適度な温度環境となる。 When air conditioning of the vehicle compartment is required, the control device 6 supplies the first air conditioning air to the vehicle compartment by operating the first blower 1, the cooler 3 and the heater 4. As a result, the passenger compartment of the vehicle has an appropriate temperature environment.

すなわち、車室の温度が所定の上限しきい値を超えて高い場合、制御装置６は、第１送風機１及び冷却器３を少なくとも作動させることにより車室に冷風を供給して車室温度を低下させる。一方、制御装置６は、車室の温度が所定の下限しきい値を超えて低い場合には、第１送風機１及び加熱器４を少なくとも作動させることにより車室に適度な風量の温風を供給して車室温度を上昇させる。 That is, when the temperature of the passenger compartment is higher than the predetermined upper limit threshold, the control device 6 supplies the cool air to the passenger compartment by operating at least the first blower 1 and the cooler 3 to control the passenger compartment temperature. Lower. On the other hand, when the temperature of the passenger compartment is lower than a predetermined lower threshold value, the control device 6 operates the first blower 1 and the heater 4 at least to generate a warm air of an appropriate air volume in the passenger compartment. Supply to raise the cabin temperature.

また、制御装置６は、バッテリの温度調節が必要な場合、第２送風機２、冷却器３、加熱器４及び第３送風機５を作動させることにより、バッテリに第２空調空気を供給する。この結果、バッテリはバッテリにとって適度な温度環境に維持される。 Further, when the temperature of the battery needs to be adjusted, the control device 6 operates the second blower 2, the cooler 3, the heater 4, and the third blower 5 to supply the second conditioned air to the battery. As a result, the battery is maintained in a temperature environment suitable for the battery.

すなわち、制御装置６は、バッテリ温度が所定の上限しきい値を超えて高い場合、第２送風機２、冷却器３及び第３送風機５を少なくとも作動させることにより、バッテリに冷風を供給してバッテリ温度を低下させる。一方、制御装置６は、バッテリ温度が所定の下限しきい値を超えて低い場合には、第２送風機２、冷却器３及び第３送風機５を少なくとも作動させることにより、バッテリに適度な風量の温風を供給してバッテリ温度を上昇させる。 That is, when the battery temperature is higher than the predetermined upper limit threshold, the control device 6 supplies at least the second blower 2, the cooler 3 and the third blower 5 to supply the cool air to the battery to supply the battery. Lower the temperature. On the other hand, when the battery temperature is lower than the predetermined lower limit threshold value, the control device 6 operates at least the second blower 2, the cooler 3 and the third blower 5 so that the battery has an appropriate air volume. Supply warm air to raise battery temperature.

本実施形態によれば、車室とバッテリとに個別に適度な風量の温度空気が送風されるので、バッテリの温度調節を実現しつつ車室の快適性の低下を従来よりも抑制することが可能である。すなわち、従来のように車室への送風とバッテリへの送風とを単一の送風機で行う場合には、バッテリを車室よりも優先して温度調節する必要がある場合に車室温度が搭乗者にとって快適でない温度になるので、車室の快適性を低下させる。 According to the present embodiment, since the temperature air having an appropriate air volume is separately blown to the vehicle compartment and the battery, it is possible to suppress the deterioration of the comfort of the vehicle compartment as compared with the conventional case while realizing the temperature control of the battery. It is possible. In other words, when air is sent to the vehicle compartment and to the battery with a single blower as in the conventional case, the vehicle compartment temperature is set when the temperature of the battery needs to be controlled prior to the vehicle compartment. This results in a temperature that is uncomfortable for the passengers, which reduces the comfort of the passenger compartment.

これに対して、本実施形態では、車室用の第１送風機１とバッテリ用の第２送風機２及び第３送風機５とが個別に設けられており、また制御装置６によって作動が個別に制御されるので、車室とバッテリとを個別に温度管理することが可能であり、よって車室の快適性を低下させることがないと共にバッテリを適切に温度管理することが可能である。 On the other hand, in the present embodiment, the first blower 1 for the passenger compartment and the second blower 2 and the third blower 5 for the battery are individually provided, and the operation is individually controlled by the control device 6. Therefore, it is possible to individually control the temperature of the vehicle compartment and the battery, so that it is possible to appropriately control the temperature of the battery without deteriorating the comfort of the vehicle compartment.

なお、上記実施形態では、単一の冷却器３及び加熱器４を設け、両者を領域分割することにより第１温調空気と第２温調空気とを生成したが、本発明はこれに限定されない。例えば、冷却器３及び加熱器４のいずれか一方あるいは両方を車室用とバッテリ用とに２つ設けてもよい。 In the above embodiment, the single cooler 3 and the heater 4 are provided, and the first temperature-controlled air and the second temperature-controlled air are generated by dividing the both into regions, but the present invention is not limited to this. Not done. For example, one or both of the cooler 3 and the heater 4 may be provided for the vehicle compartment and the battery.

このような変形例では、第１温調空気の車室への供給風量及び第２温調空気のバッテリへの供給風量だけではなく、第１温調空気及び第２温調空気の温度をも個別に調節することが可能になるので、より適切な車室の温度管理及びバッテリの温度管理を実現することが可能となる。 In such a modified example, not only the amount of air supplied to the vehicle compartment of the first temperature-controlled air and the amount of air supplied to the battery of the second temperature-controlled air, but also the temperatures of the first temperature-controlled air and the second temperature-controlled air are detected. Since they can be adjusted individually, it is possible to realize more appropriate temperature control of the vehicle interior and battery.
