VEHICLE, ELECTRIC DEVICE, AND POWER TRANSMISSION/RECEPTION SYSTEM

摘要

A vehicle includes: a power reception device (110) that receives power for running the vehicle (100) in a non-contact manner using electromagnetic field resonance; and a power transmission device (184) that transmits power supplied to an electric device inside the vehicle in a non-contact manner using the electromagnetic field resonance. A frequency of an electromagnetic field used by the power reception device to receive power is set to be different from a frequency of an electromagnetic field used by the power transmission device to transmit power. It is desirable to set the frequency of the electromagnetic field used by the power reception device to receive power and the frequency of the electromagnetic field used by the power transmission device to transmit power such that the frequency of the electromagnetic field used by the power reception device to receive power is lower than the frequency of the electromagnetic field used by the power transmission device to transmit power. It is even more desirable for the power received by the power reception device in a non-contact manner from an external power transmission device provided outside the vehicle to be larger than the power transmitted by the power transmission device to the electric device in a non-contact manner.
