Abstract
In-motion WPT can solve the problem of electric vehicles that is short cruising range. Therefore transfer energy is one of the biggest problem of In-motion WPT. To prevent contamination is the best way to increase transfer energy for in-motion WPT because of its short time use and long time of contamination detection system. Here, WPT system that can transfer through tire and wheel is proposed and also its coils' mutual inductance model is proposed.
