<P>PROBLEM TO BE SOLVED: To provide an efficient radio power transmitting system which suspends power transmission, when a foreign object is placed on a charge plate, and ensures charging at a stable voltage, even if a contactless power receiving device moves during charging. <P>SOLUTION: Power transmission is controlled, in such a way that a power signal sent from a primary side charging core of a contactless power transmitting device is received by a secondary side charging core of a contactless power receiving device to charge up a power supply. A charge control method for the system includes a standby mode step (S01); a specific ID recognizing step (S02) of recognizing a specific ID signal for the contactless power receiving device; a full power transmitting step (S03) of transmitting full power upon reception of a normal specific ID; a charge adjusting step (S04) of adjusting a level of charging based on the charge information of the contactless power receiving device; and a full charge state step (S05) of suspending charging operation upon the reception of information of full charge. <P>COPYRIGHT: (C)2009,JPO&INPIT |
