NON-CONTACT POWER SUPPLY DEVICE, NON-CONTACT POWER TRANSMISSION SYSTEM, AND NON-CONTACT POWER SUPPLY METHOD

摘要

PROBLEM TO BE SOLVED: To provide a non-contact power supply device capable of reducing power consumption.SOLUTION: A non-contact power supply device 10 according to one embodiment performs non-contact power supply to a vehicle 20. The non-contact power supply device 10 comprises: a radio communication unit 13 for performing radio communication with the vehicle 20; a power supply coil 12 for performing power supply to the vehicle 20 by using electromagnetic coupling according to the radio communication by the radio communication unit 13; and a parking detection sensor 14 for detecting that the vehicle 20 is parked at a predetermined position. When the parking detection sensor 14 detects that the vehicle 20 has been parked at a predetermined position, the radio communication unit 13 is started.
