<P>PROBLEM TO BE SOLVED: To provide a resonance type non-contact charging system for efficiently charging while the accuracy of the stopping position of a moving object is released. <P>SOLUTION: The resonance type non-contact charging system includes an AC power supply unit 11, a primary coil 12a, etc., selectively connected to the AC power supply unit 11, a primary side resonance coil 13a, etc., a secondary side resonance coil 21, a secondary coil 22, a charger 23 connected to the secondary coil 22 and supplied with power, and a secondary battery 24 connected to the charger 23. The secondary side resonance coil 21, the secondary coil 22, the charger 23 and the secondary battery 24 are mounted on a vehicle. while the vehicle stops for charging, a combination having a larger power transmission efficiency from among the plurality of primary side resonance coil 13a, etc., and the secondary side resonance coil 21 is selected, non-contact power transmission is executed from the AC power supply unit 11 via the resonance system 16, and the secondary battery 24 is charged via the charger 23. <P>COPYRIGHT: (C)2010,JPO&INPIT |
