At least one inverter (52) is heated by causing an inverter heat generation control unit to pass a predetermined current through the inverter for a predetermined time, and heating of the at least one inverter causes a high-voltage battery (54) (storage battery) to warm up via a cooling circuit. Accordingly, control for warmup of the high-voltage battery (storage battery) is simply performed by passing the predetermined current through the inverter for a predetermined time. This inverter heat generation control can also be applied to a vehicle not including a step-up converter.
