A battery assembly (10) for a vehicle, including a battery 12 with a plurality of battery cells 14 and with a coolant circuit 16 configured to transfer heat from or to the battery. The coolant circuit includes at least one heat exchanger 18 which is in contact with at least one of the battery cells. The heat exchanger is at least partially made of an electrically conductive material. The battery assembly further includes a power supply unit 62 configured to pass electrical current through the heat exchanger. The surfaces of the heat exchanger which contact the battery cells or coolant may have an electrically insulating coating. The assembly may include a temperature sensor for monitoring the cells, and a control unit 64 configured to actuate the power supply unit dependent on the temperature of the cells. A refrigerant circuit (36) including compressor (38), condenser (40), chiller (34) and expansion device (42) may take up heat from the coolant in the coolant circuit. |
