New Electric Vehicle Powered by Road Coils Receives Upgrade

Science Society Technology

Kashiwa, Chiba Pref., Oct. 10 (Jiji Press)--A team of Japanese developers said Thursday they have succeeded in sharply upgrading their new type of electric vehicle that uses electricity transmitted from coils embedded in road surfaces.

The electric vehicle uses motors installed inside its wheels, eliminating the need for parts to connect the wheels with an external motor and making the vehicle lighter. The motors are powered by electricity transmitted from road coils through magnetism, allowing the motors to be wirelessly charged.

"In the future, (cars) will not need to be recharged if they can receive electricity while running or stopping on coils laid in parts of expressways or in roads near intersections," Hiroshi Fujimoto, associate professor at the University of Tokyo and a member of the development team, said.

The mechanism reduces the necessary battery capacity, lowering the weight and cost of the vehicle. The team, which also includes bearing producer NSK Ltd. <6471> and electronic parts maker Rohm Co. <6963>, aims to use the technology to develop a cheap, convenient electric vehicle system.

Field tests are slated to be held near the university's Kashiwa campus in Chiba Prefecture, east of Tokyo, in 2025.
