ELECTRIC POWER TRANSMISSION DEVICE, ELECTRIC POWER RECEPTION DEVICE, VEHICLE, AND NON-CONTACT ELECTRIC POWER FEED SYSTEM
First Claim
1. An electric power transmission device for supplying electric power to an electric power reception device in a non-contact manner, comprising:
- an electric power transmission unit capable of supplying electric power to the electric power reception device in a non-contact manner;
a communication unit for radio communication with the electric power reception device; and
a control device for controlling the electric power transmission unit,the control device determining whether a specified electric power reception device is an electric power reception device to which electric power is to be transmitted from the electric power transmission unit based on information from the electric power reception device specified as an electric power transmission target through radio communication by the communication unit, when electric power transmitted from the electric power transmission unit is varied while the electric power transmission unit transmits electric power.

Abstract
In a non-contact electric power feed system, electric power is supplied in a non-contact manner from an electric power transmission device to a vehicle representing an electric power reception device. The electric power transmission device includes an electric power transmission unit, a communication unit for radio communication with the electric power reception device, and a control device for controlling the electric power transmission unit. The control device varies transmitted electric power from the electric power transmission unit while the electric power transmission unit transmits electric power, and determines whether or not pairing between the vehicle specified as an electric power transmission target and the electric power transmission unit is appropriate, based on information on variation in electric power from the vehicle specified as the electric power transmission target through radio communication.
