To cool charging related components (a battery and a PCU etc.) efficiently during external charging.SOLUTION: During external charging in which a PCU 30 and a battery 32 generate heat easily, a part of a cooling fluid of an HV cooling circuit 28 is circulated through a first communication passage 66 and a second communication passage 70 to be cooled by an engine radiator 42 provided at an engine cooling circuit 26. In other words, during the external charging, the cooling fluid for cooling the PCU 30 and the battery 32 is cooled by an HV radiator 62 of the HV cooling circuit 28 and the engine radiator 42 of the engine cooling circuit 26 and the cooling fluid efficiently cools the PCU 30 and the battery 32 to inhibit temperature rise.SELECTED DRAWING: Figure 3

    【課題】外部充電時に充電関連部品(バッテリやPCUなど)を効率良く冷却できるようにする。【解決手段】PCU30およびバッテリ32が発熱し易い外部充電中は、HV冷却回路28の冷却流体の一部が、第1連通路66および第2連通路70を通って循環させられ、エンジン冷却回路26に設けられたエンジンラジエータ42によって冷却される。すなわち、外部充電中は、PCU30およびバッテリ32を冷却する冷却流体が、HV冷却回路28のHVラジエータ62およびエンジン冷却回路26のエンジンラジエータ42の両方で冷却されるようになり、その冷却流体によりPCU30およびバッテリ32を効率良く冷却して温度上昇を抑制することができる。【選択図】図3
