<p><P>PROBLEM TO BE SOLVED: To reduce power consumption. <P>SOLUTION: In charging a battery 14 mounted on a vehicle 13, a vehicle control device 41 of a contactless charging system 10 transmits power via a vehicle oscillation circuit 42 and a vehicle transmission antenna 43 mounted on the vehicle 13 and feeds the power to a control device 21 via a reception antenna 25, a reception side rectification circuit 24 and an electric path switch section 23 of a charging station 12 to start the control device 21 being stopped. After the starting, the control device 21 switches to powering from an internal power supply 22, and starts to transmit power from a transmission side rectification circuit 27, a DC/DC converter 28, an oscillation circuit 29 and a transmission antenna 30 to a vehicle reception antenna 45, a vehicle rectification circuit 46 and a vehicle DC/DC converter 47 of the vehicle 13. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
