Abstract:
PROBLEM TO BE SOLVED: To provide a non-contact transmission device, non-contact power reception device, and non-contact power transmission system, capable of concurrently achieving foreign matter detection and radio communication without causing a device cost increase.SOLUTION: A controller 485 detects foreign matter between a power transmission coil and a power reception coil by sequentially switching and using a plurality of coil pairs. The controller 485 executes radio communication in a frequency band different from a frequency band used for detection of foreign matter relative to a vehicle 100 by using a second coil 478 in use among a plurality of second coils 478 in an antenna for radio communication.SELECTED DRAWING: Figure 4
