A vehicle power converter mounted on a vehicle includes connectors, an AC-DC power conversion circuit, a smoothing capacitor, a bidirectional DC-DC power conversion circuit, a switch that is provided between the smoothing capacitor and at least one of the connectors, and a controller. The controller executes battery charging preparation operation when the controller determines that the vehicle power converter is connected to the external power supply as follows: after the controller controls operation of the bidirectional DC-DC power conversion circuit while keeping a connection state between the smoothing capacitor and the connectors in a disconnected state by the switch such that a power output from the battery is supplied to the smoothing capacitor, the controller causes a connection state of the switch to transition from a disconnected state to a connected state.
