Abstract: In a discharging operation of a vehicle storage battery, a controller switches between a full-wave rectification operation of full-wave rectify a voltage across a second winding while maintaining a second short circuit in an open state, and a full-wave voltage doubling rectification operation of full-wave voltage doubling rectify a voltage across second winding while maintaining second short circuit in a closed state, based on magnitude relationship between DC voltage across first terminals and DC voltage across second terminals. In a charging operation, controller switches between a full-wave rectification operation of full-wave rectify a voltage across a first winding while maintaining a first short circuit in an open state, and a full-wave voltage doubling rectification operation of full-wave voltage doubling rectify a voltage across first winding while maintaining first short circuit in a closed state, based on magnitude relationship between DC voltage across first terminals and DC voltage across second terminals.

Abstract: A first voltmeter measures a voltage of a connector held by a holder of a vehicle power device. A second voltmeter measures a voltage of a second port of a power converter. when the connector is held by the holder. A controller detects presence or absence of a malfunction in a connector-side switch based on: measurement results of the voltmeters while controlling the connector-side switch so that electrical connection between the second port and the connector is broken; and measurement results of the voltmeters while controlling the connector-side switch so that the electrical connection is made.
