POWER RECEIVING DEVICE
First Claim
1. A power receiving device comprising:
- a module including a power receiving unit and a device unit, the power receiving unit including a coil and a capacitor, the power receiving unit being configured to contactlessly receive electric power that is output from a power transmitting device, the device unit including a coil and a capacitor, the device unit being provided between the power receiving unit and an electrical storage device, the electrical storage device being configured to store electric power received by the power receiving unit;
a first relay provided between the device unit and the electrical storage device;
an alternating-current power supply unit configured to supply alternating current to a power line provided closer to the power receiving unit than the first relay;
a current sensor configured to detect a current flowing through the power line; and
an electronic control unit configured to, when alternating current is supplied from the alternating-current power supply unit to the power line in a case where the first relay is in a power interrupted state, detect whether there is an abnormality in at least one of the coil or the capacitor based on a detected value of the current sensor.

Abstract
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.
