POWER RECEIVING DEVICE, POWER TRANSMITTING DEVICE, VEHICLE, AND CONTACTLESS POWER SUPPLY SYSTEM
First Claim
1. A power receiving device for contactlessly receiving electric power, transferred from a power transmitting device, through electromagnetic resonance, comprising:
- a power receiving unit configured to carry out electromagnetic resonance with a power transmitting unit included in the power transmitting device to receive electric power from the power transmitting device; and
a discharging unit configured to discharge received electric power received by the power receiving unit when there is an abnormality in the power receiving device.

Abstract
A power supply system includes: a power transmitting device that includes a power transmitting unit; and a vehicle that includes a power receiving unit, and contactlessly transfers electric power between the power transmitting device and the vehicle through electromagnetic resonance. When there is an abnormality that a power receiving mechanism of the vehicle cannot receive electric power, a vehicle ECU causes the power transmitting device to stop power transmission, opens a relay and further discharges remaining electric power by the discharging unit.
