To provide a power supply system for vehicle capable of quickly charging a power storage device by power supplied from an external part, in a low temperature environment.SOLUTION: A power supply system 1 comprises: a first battery B1; a second battery B2; a heater H; a power circuit 2 on which the batteries B1, B2 and the heater H are arranged; a first external charging unit 5 for supplying power on an external part of a vehicle V to the power circuit 2; and an ECU 7 for controlling the power circuit 2 and the first external charging unit 5. The ECU 7 executes discharge/heating control for heating the first battery B1 by discharging power to the second battery B2 from the first battery B1 in execution of a heater heating control for heating the first battery B1 by the heater H by driving the heater H by power supplied from the AC charger 5, and charges the first battery B1 by power supplied from the AC charger 5 when temperature of the first battery B1 becomes equal to or greater than heating determination temperature.SELECTED DRAWING: Figure 3B
【課題】低温環境下において、外部から供給される電力で速やかに蓄電装置を充電できる車両の電源システムを提供すること。【解決手段】電源システム1は、第1バッテリB1と、第2バッテリB2と、ヒータHと、バッテリB1,B2とヒータHとが設けられた電力回路2と、車両Vの外部の電力を電力回路2へ供給する第1外部充電ユニット5と、電力回路2及び第1外部充電ユニット5を制御するECU7と、を備える。ECU7は、交流充電器5から供給される電力でヒータHを駆動することによってこのヒータHで第1バッテリB1を加温するヒータ加温制御の実行中に、第1バッテリB1から第2バッテリB2へ電力を放電することで第1バッテリB1を加温する放電加温制御を実行し、第1バッテリB1の温度が加温判定温度以上になった後に交流充電器5から供給される電力で第1バッテリB1を充電する。【選択図】図3B
