NON-CONTACT POWER TRANSMISSION SYSTEM

WIPO Patent Application WO/2011/093291

A1

Provided is a non-contact power transmission system wherein, when transmitting power, it is possible to effectively perform non-contact power transmission by means of a series of power transmitting sequences which begins with recognizing and setting the power transmitting conditions, then with beginning the power transmission, and ends with completing the power transmission. Disclosed is a system for transmitting power in a non-contact manner to devices, such as vehicles, that use electric energy as the power source, which is provided with a power reception side antenna that is mounted on the device and that receives the power, and a transmission side antenna that sends power to the power reception side antenna. When AC electric power which vibrates at a resonation frequency is being transmitted between the antennae by means of electromagnetic coupling, once it is detected that the power reception side antenna is located within an area in which the power transmission side antenna can feed power, power begins to be transmitted, and once the power source mounted on the device, which is being charged by means of the power being transmitted, finishes charging, the transmission of power stops.
