To make this work, an EV with special tires draws energy directly from steel paths embedded in the road, according to The Japan Times [ http://www.japantimes.co.jp/news/2016/03/18/business/first-ev-without-battery-unveiled-aichi/ ]. At this early stage, the solution isn't very practical, though. As the tires roll, steel wires in them carry energy from the steel plates in the road to the electric motor. The university already built a full-scale proof of concept on a 98-foot test course, and the EV reached about six miles per hour there. "Acceleration was smooth, and the ride was comfortable." professor Takashi Ohira, told The Japan Times. Ohira has been working on ways to make batteries less necessary for EVs for several years. In 2011, he proposed embedding radio frequency transmitters [ http://www.autoblog.com/2011/08/22/japanese-researchers-can-deliver-power-to-your-wheels-by-radio/ ] in the road, and using the steel belts in the tires and special equipment in the vehicle to convert the signal to electricity. This test seems to be a development of that research. While this method works, there are a lot of problems that still need solutions. For example, how much energy would you need to flow through the road to power thousands of vehicles every day? Also, embedding the necessary equipment in the road would be a gargantuan undertaking. It's difficult to imagine so much money going to such a massive infrastructure project, but that doesn't mean that Ohira is alone in his quest to turn roads into charging surfaces. Volvo has tested inductive charging in short sections of road [ http://www.autoblog.com/2014/05/27/volvo-inductive-charging-electric-roads/ ] to top up the batteries in a city boss while it was on the move. Last year, Goodyear also proposed tires than can charge a car [ http://www.autoblog.com/2015/03/06/goodyear-imagines-a-tire-that-can-charge-your-ev/ ]. And HaloIPT [ http://www.autoblog.com/2010/11/09/uk-based-haloipt-introduces-in-road-charging-system-for-electric/ ] and the Korea Advanced Institute of Technology [ http://www.autoblog.com/2009/09/02/korean-electric-car-gets-a-charge-an-induction-charge-from-t/ ] have been tinkering with the idea for years.

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. After driving the vehicle on the 30-meter-long course at the speed of about 10 kilometers per hour, Professor Takashi Ohira, who is involved in the vehicle's development, said, "Acceleration was smooth, and the ride was comfortable." 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.
