Development of Second Generation Wireless In-Wheel Motor with Dynamic Wireless Power Transfer

The authors have developed the wireless in-wheel motor (W-IWM) to solve the power-lines disconnection problem of the In-Wheel Motor (IWM) radically. In this paper, the advanced system of the W-IWM (W-IWM2) is proposed. This system has the capability of the Dynamic Wireless Power Transfer (D-WPT) on its wheel-side. The D-WPT technology can drastically extend the driving range of electric vehicles. In addition, the Lithium-ion Capacitor (LiC) is installed in the wheel-side of the W-IWM2. The LiC can effectively charge the regenerative brea
