PROBLEM TO BE SOLVED: To suppress breakage of a device by preventing an excess current from flowing into the device of a power converter.SOLUTION: A shift position SP is set to a parking position, an electric load is connected to an external power feed unit, and a step-up converter is disconnected by a relay. In this state, a battery storage capacity ratio SOC falls below a threshold Sset. The relay is turned on to connect the step-up converter to the battery. Power from an engine is used to generate electricity using a motor. In this case, when a voltage VH of a smoothing capacitor falls below a battery voltage Vb, the motor is controlled to be regenerated so that a generated current becomes equal to or smaller than a value Iset. Namely, the motor is controlled to be regenerated so that the generated power becomes smaller than that when the voltage VH of the smoothing capacitor is equal to or larger than the battery voltage Vb. Accordingly, an excess current can be prevented from flowing into a transistor or the like of the step-up converter, and a device such as the transistor can be prevented from being broken. |
