EV In-wheel Motors Powered by Coils on Road

A Japanese research group developed a system that wirelessly transmits electricity to a running electric vehicle (EV). The group is led by Hiroshi Fujimoto, professor of the Graduate School of Frontier Sciences, the University of Tokyo. For the development of the system, the group collaborated with Toyo Denki Seizo KK and NSK Ltd. The new system wirelessly transmits power from the road to the in-wheel motors (IWMs) of the front wheels. The research group applied the newly-developed IWM to a test vehicle developed based on Mitsubishi Motors Corp's "i-MiEV" EV and showed an outdoor test of the vehicle to the press. Three power transmitting coils (size: 1.0 x 0.5m each) were placed on the road, and the EV ran at a speed of about 15km/h (approx 9.3mph). The University of Tokyo and others developed an EV equipped with a system that enables to transmit electricity when the vehic...
