A crowbar circuit includes a diode bridge and switching elements, and is configured to rectify the full wave of AC power between the power lines and output the rectified AC power to a positive electrode line and a negative electrode line. A capacitor is connected between the power line and the negative electrode line. When a detection value of a current sensor indicates that the power reception device is not receiving power normally, a charging ECU stops the power conversion operation of the power transmission device, and thereafter outputs at least one of short circuit commands to the crowbar circuit so as to determine whether or not a malfunction is present in the crowbar circuit based on a detection value of the voltage sensor.
