Japan begins testing on-the-go wireless charging system for electric vehicles

Contact networks, which for decades powered trams and trolleybuses, in the future will try to go underground, and the transmission of electricity to the power plant of promising modes of transport will be carried out by electromagnetic induction. In any case, Obayashi and Denso in Japan have started testing a similar technology that could see city streets by 2025.

The main purpose of such systems is the continuous recharging of public electric vehicles. Cables and induction circuits are hidden under the roadway, which allows the traction battery of the electric bus moving along the route to be continuously fed. The latter can be made lighter and more compact due to such a support, which improves the vehicle’s ability to carry a payload in the form of passengers.

Construction company Obayashi, as mentioned earlier Nikkei Asian Review, has partnered with auto parts supplier Denso to build a 15km test track at its Tokyo research center to test contactless charging technology for electric vehicles on the go. While Denso is in charge of the charging infrastructure in tandem, Obayashi has developed fiber-reinforced concrete that makes it possible to cover the charging circles mounted in the roadway with sufficiently thin, but at the same time durable tiles that can withstand intensive use in a metropolitan area.

As already mentioned, similar solutions are already being tested by European car manufacturers. Tests will be conducted in Japan by March next year, and if the solution proves itself from the best side, practical implementation will be worked on by 2025. Obayashi is also working with cable maker Furukawa Electric on a project to run cables to power chargers along roads. According to the participants of the initiative, the development of such infrastructure will contribute to the popularization of electric transport. At the same time, telecommunications will be shifted, allowing “smart” cars to exchange information with data centers at high speeds along the entire route.
