NON-CONTACT POWER RECEPTION DEVICE AND VEHICLE COMPRISING THE SAME, NON-CONTACT POWER TRANSMISSION DEVICE, AND NON-CONTACT POWER TRANSMISSION SYSTEM

摘要

PROBLEM TO BE SOLVED: To suppress reduction in power transmission efficiency while reducing a leakage magnetic field in a non-contact power transmission system for transmitting power in a non-contact manner.SOLUTION: A vehicle 100 comprises a power reception coil unit 110, a cancel coil unit 112, a conductor plate 114, an oscillator 116 and a vehicle ECU 150. The power reception coil unit 110 receives power transmitted from a power transmission coil unit 230 of a power transmission device 200 in a non-contact manner. The cancel coil unit 112 receives AC current from the oscillator 116 controlled by the vehicle ECU 150, and generates a magnetic field for canceling a leakage magnetic field generated from the power reception coil unit 110 when the power reception coil unit 110 receives power. The conductor plate 114 is disposed between the power reception coil unit 110 and the cancel coil unit 112.
