POWER TRANSMISSION UNIT, POWER TRANSMISSION DEVICE, POWER RECEPTION DEVICE, VEHICLE AND CONTACTLESS POWER SUPPLY SYSTEM

摘要

PROBLEM TO BE SOLVED: To efficiently pair each transmission unit with each vehicle in a contactless power supply system having a plurality of transmission units.SOLUTION: A contactless power supply system 10 transmits power from a power transmission device 20 to vehicles 100A, 100B in a contactless manner. The power transmission device 20 includes a plurality of power transmission units 200A-200C. Each vehicle can mutually radio communicate with the power transmission device 20. The power transmission device 20 allows the plurality of power transmission units 200A-200C to perform simultaneous test power transmission. On receipt of power by the test power transmission, the vehicles 100A, 100B transmits a power reception success report to the power transmission device 20. If the power reception success report is received from a plurality of vehicles, the power transmission device individually re-executes test power transmission to each power reception unit having successful test power transmission.
