Feasibility Study on In-motion Wireless Power Transfer System Before Traffic Lights Section

In order to improve usability of Electric vehicles (EVs), in-motion Wireless Power Transfer (WPT) technology is one of a game changing solution. In order to maximize the benefit of an in-motion WPT system, it is necessary to find the optimal installation location. In the previous study, the authors found that 30 m length section before traffic lights is the best location by analyzing actual driving data on urban public roads in Japan. In this study, the authors have carried out feasibility study on implementation of in-motion WPT system. Transmit power and efficiency of a virtual in-motion WPT system are simulated.
