In a power receiving device, a module including a power receiving unit, a transformer, a filter circuit and a rectifier circuit includes a coil and a capacitor. An alternating-current power supply unit is configured to be able to supply alternating current to the power receiving device on a side closer to the power receiving unit than a relay. A vehicle electronic control unit is configured to, when alternating current is supplied from the alternating-current power supply unit in a case where the relay is turned off, detect whether there is an abnormality in at least one of the coil or the capacitor on the basis of a detected value of a current sensor.
