The Concept of a Future Electric Vehicle and the Development of an Electric Motorcycle 891695

It is shown that an electric vehicle (EV) will have an excellent performance by making extensive use of new technologies and new design concepts/by the computer simulation. In case of a 4 person passenger car, a 390krn range in city drive/180km/h maximum velocity and 21sec from 0 to 400m acceleration time will be achieved/by using a sodium-sulfur (NaS) battery whose energy density is 120Wh/kg and weight is 265kg. An electric motor cycle is developed by adopting the new technologies. A brushless DC motor which uses a rareearth cobalt magnet was set inside the rear wheel to utilize the direct drive system. The maximum speed is 55km/h and the range is 56km in 30km/h constant speed driving.
