ABSTRACT:
A battery temperature regulating apparatus efficiently controls the charging temperature of a battery assembly which serves as a power source to energize a propulsive motor on an electric vehicle to run on a road. A fluid jacket is disposed in heat exchange relationship with the battery assembly and supplied with a coolant to regulate the temperature of the battery assembly with a radiator or an electric heater for allowing the battery assembly to be charged in a temperature range from 20.degree. C. to 35.degree. C., for example, which is optimum for the charging of the battery assembly. The battery temperature regulating apparatus can maintain the optimum temperature range more reliably than a conventional apparatus which regulates the temperature of the battery assembly as it is charged with a forced flow of hot air or cool air, and can reduce the electric energy consumption to 1/3 of that of the conventional apparatus.
