2 1) 2) 3) 4) 5) 6) Development of Second Generation Wireless In-Wheel Motor with Dynamic Wireless Power Transfer Hiroshi Fujimoto Takuma Takeuchi Katsuhiro Hata Takehiro Imura Motoki Sato Daisuke Gunji The authors have developed Wireless In-Wheel Motor (W-IWM) to solve power-lines disconnection problem of In-Wheel Motor (IWM) radically. In this paper, the advanced system of W-IWM (W-IWM2) is proposed. This system has capability of Dynamic Wireless Power Transfer (D-WPT) on its wheel-side. D-WPT technology can drastically extend driving range of electric vehicles. In addition, Lithium-ion Capacitor (LiC) is installed in wheel-side of the W-IWM2. LiC can effectively charge regenerative breaking energy. This paper discussed the development of the W-IWM2. The experimental results show the effectiveness of W-IWM2.
