POWER RECEIVING DEVICE, POWER TRANSMITTING DEVICE, VEHICLE, AND CONTACTLESS POWER SUPPLY SYSTEM

摘要

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