<P>PROBLEM TO BE SOLVED: To further promptly operate a control part even if a voltage of a secondary-side power supply lowers due to a charge current at non-contact charging. <P>SOLUTION: This charge control device includes a secondary power supply 1 which generates power by electromagnetic induction action according to a magnetic field which is generated by a primary power supply, a secondary battery 7-1 charged by the generated power, a capacitor 4-2 which is charged by the generated power and is shorter in time than the secondary battery 7-1 until it is charged to a preset predetermined value, and a control part 6 which is operated when a voltage of the capacitor 4-2 exceeds the predetermined value, and controls charging the secondary battery 7-1 by opening and closing a power feed passage to the secondary battery 7-1 from the secondary power supply 1. <P>COPYRIGHT: (C)2011,JPO&INPIT |
