Abstract

Wireless power transfer (WPT) has been realized by Teslacoil by Nicola Tesla since 1889. In recent years, WPT is often used for charging laptops and smartphones, and their output is approximately 10 W to 100 W. On the other hand, for the Electric Vehicle (EV) charging several kilowatts transfer is required in WPT. WPT has advantages such as no exposure of contacts, no sparks when connecting terminals, and no wear of contacts. These advantages make it ideal for charging electric vehicles. However, in the magnetic induction method that has been conventionally used, the transmission distance is short. On the other hand, in the Strong Coupled Magnetic Resonance (SCMR) method proposed in 2010 by MIT, the long distance power transmission is succeeded. [1]. However, the resonant coil used in [1] has a large volume due to its height. In addition, there is no example of high power transmission by using this method. In this paper, a high power thin antenna using 13.56 MHz, which can apply to EV charging, is proposed. The theory is confirmed by some experiments. As a result, the maximum antenna efficiency 93.4%, and maximum power 2.4kW transmission with 84.0% efficiency is realized under 300mm power transmission distance with 3.2mm coil thickness.
