POWER RECEPTION DEVICE, VEHICLE, POWER TRANSMISSION DEVICE, AND NON-CONTACT POWER SUPPLY SYSTEM

摘要

PROBLEM TO BE SOLVED: To properly detect a foreign object between a power transmission device and a power reception device and suppress the influences on the foreign object in a non-contact power supply system.

SOLUTION: A non-contact power supply system 10 transfers electric power from a power transmission part 220 to a power reception part 210 in a non-contact manner through electromagnetic resonance. The non-contact power supply system 10 includes: an infrared sensor 122 for detecting motion of an object entering between the power transmission part 220 and the power reception part 110; and a thermo camera 120 for detecting the information regarding the temperature distribution between the power transmission part 220 and the power reception part 110. A vehicle ECU 180 determines the presence of a foreign object between the power transmission part 220 and the power reception part 110 on the basis of the information detected by the infrared sensor 122 and the thermo camera 120.
