PURPOSE:To prevent deterioration of characteristics by stopping charging operation of main battery when power demand is low. CONSTITUTION:When power demand (P) of vehicle is lower than the minimum output power (pGmin) of 8 generator 12, maximum charging charging current (pCHGmax) of a main battery 16 is determined based on SOC of the main battery 16. If PGmin-P>=PCHGmax, a vehicle ECU 30 delivers commands to an engine ECU 32 and a field controller 34 to stop or bring the engine 10 into idling state thus bringing the field current of the generator 12 to zero. Consequently, output power from the generator 12 is interrupted and a motor 20 is driven with the output from the main battery 16 thus interruting charging operation of the main battery 16. Since the main battery 16 is charged under a state where SOC is high, production of gas or heating of the main battery 16 is prevented and the characteristics of the main battery 16 are prevented from deterioration. |
