Wireless Power Transmission System(WPT) based on magnetic resonant method with up to 1kW power transmit capability through 10 to 30cm gap for charging battery installed on EV has completed for proving evaluation. Square type power Transmitt/Receive Couplers have used. To suppress near-by outside magnetic field, shiled plates have been attached. Simulation result of near-by magnetic field have been evaluated. The power transmit efficiency from output of 13.56MHz RF amp to the input of battery has achieved around 88%.
