<p><P>PROBLEM TO BE SOLVED: To provide a wireless power supply system which efficiently supplies electric energy for charging in a non contact manner. <P>SOLUTION: A control coil 3 and a secondary coil for charging 4 are provided at a vehicle. Multiple primary coils are provided on a road surface of a charging area. When the vehicle is driven at the charging area, the control coil 3 and the secondary coil for the charging 4 of the vehicle 2 are positioned so as to overlap with the primary coils on the road surface. Battery authorization, charging information, and charging instructions are transmitted and received by communication means 7, 8, which enable road-vehicle communication conducted by electric waves through the control coil 3 and the primary coils. Then, a battery 6 of the vehicle 2 is charged through resonance magnetic coupling between the secondary coil for the charing 4 and the primary coils according to the charging information. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
