ABSTRACT:
A battery temperature control system in an electric automobile which is equipped with an air conditioner for supplying a cool or warm air into a passenger compartment and which travels by using batteries as a power source accommodated in a battery chamber. The system includes a battery temperature sensor for detecting a temperature of the battery, a control unit adapted to drive the air conditioner in an air-cooling mode when the battery temperature detected by the temperature sensor is higher than a predetermined upper limit, and in an air-heating mode when the battery temperature detected by the temperature sensor is lower than a predetermined lower limit. An air intake port is provided in the battery chamber for introducing an air supplied from the air conditioner into the battery chamber. Further, in order to obtain a sufficiently warm air even when the atmospheric temperature is low, an auxiliary heat exchanger 28 which is heated by the combustion heater 29 also is provided.
