Abstract
After the vehicle is parked, when the SOC of the auxiliary battery becomes equal to or less than a threshold A, the ECU turns off the switch; when it is predicted that the engine will be started for the first time, the ECU turns on the switch; when the capacitor temperature is equal to or lower than a threshold B, the ECU turns on the heater and starts to charge the capacitor; when the engine is startable and when an engine start operation is performed by the user, the ECU supplies the electric power in the capacitor to the engine starter.
