電動車両の基本技術とその発展の動向

抄録

The three great inventions were done in Japan. These were, Nd-Fe magnet for a motor, Li-ion battery and GaN transistor for an inverter. These technologies are matured to be used for electric vehicles, to realize high performance, comfortable and low cost electric vehicles. The way to use these technology is another importance. In-wheel motor including inverter and a new concept Li-ion battery are indispensable for wide spread of electric vehicles. 700km range per charge with 35kWh battery, wide space in the cabin and high drive performance will be possible by adopting all the technology.
