Electric Vehicle that can Run Without a Battey has been Unveiled
Toyohashi University of Technology and Taisei Corp. unveiled Friday what they say is the world’s first electric vehicle that runs without carrying a battery, using special tires that draw power from an electrified road surface.
In a driving test at the school in Toyohashi, Aichi Prefecture, a small electric vehicle moved quietly on a test course in which two electrified steel paths were laid parallel beneath at the width of the vehicle. Steel wires were embedded into the tires to provide a conduit for the energy to drive the vehicle.
Regular electric vehicles are not suitable for long-distance driving due to the relatively small capacity of the batteries loaded on them.
The newly developed EV can only run on electrified roads.
Ohira said that if expressways are fitted with the technology, EVs can run a long distance. “We can then reduce the size of batteries for nonexpressway driving,” he said.
