Abstract

A power supply system (10) includes: a power transmitting device (200) comprising a power transmitting unit (220); and a vehicle (100) comprising a power receiving unit (110) and contactlessly transferring electric power between the power transmitting device (200) and the vehicle (100) through electromagnetic resonance. When an abnormality that a power receiving mechanism of the vehicle (100) cannot receive electric power exists, a vehicle ECU (300) causes the power transmitting device (200) to stop power transmission, a relay (RY20) is opened and remaining electric power is further discharged by the discharging unit (186).

Description

technical field [0001] The present invention relates to a power receiving device, a power transmitting device, a vehicle, and a non-contact power supply system, and more particularly, the present invention relates to a non-contact power supply technology that transmits power using electromagnetic resonance. Background technique [0002] Vehicles such as electric vehicles and hybrid vehicles are in the spotlight as environmentally friendly vehicles. These vehicles each include an electric motor that generates driving force for traveling and a rechargeable power storage device that stores electric power supplied to the electric motor. It should be noted that a hybrid vehicle includes a vehicle that further includes both an internal combustion engine and an electric motor as power sources, a vehicle that further includes both a fuel cell and an electric storage device as a DC power source for driving the vehicle, and the like. [0003] In recent years, wireless power transmiss...
