ABSTRACT:
The car power source apparatus is provided with a car driving battery, a heater which heats the driving battery, a control circuit which controls power to the heater, and a temperature sensor to detect battery temperature and issue a detected temperature signal to the control circuit. The control circuit is provided with a timer which stores a warming-time to maintain the driving battery in a warmed-up condition via the heater after the car ignition switch has been turned off. During the warming-time, which is until the timer times-out with the ignition switch turned to the off state, the control circuit controls power to the heater to maintain the driving battery in a warmed-up condition.
