Denso to trial technology that charges EVs on the road

Denso will start trialling new integrated electric vehicle (EV) charging infrastructure technology next year that can top-up vehicles while they’re at a standstill in traffic.

The automotive components and technology company has already been conducting collaborative industry and academia demonstration testing and from 2022, will gradually start more testing for use in its own factory locations first over the next three years, ahead of any potential public road infrastructure projects.

The company believes installing charging technology within roads themselves will help solve the longer term issue of public charging infrastructure, which could struggle to keep pace with the number of EVs that will eventually be on the roads.

Keisuke Tani, an engineer within Denso’s Electrification Systems Engineering Division, said: “The charging devices are embedded in the road, and they provide electricity to vehicles when they pass over or halt on the devices.

“The underlying mechanism is very simple. The key point is to limit the charging points by coordinating infrastructure and mobility in order to minimize the energy consumption.”

Tani said the technology comes into its own when city driving, where in busy areas many vehicles spend half the time sitting at red lights or at rest due to congestion.

The technology is also expected to work particularly well with vehicles that serve distribution centres, plants and other facilities that operate non-stop throughout the day.

Denso said that by installing electric power charging systems in these locations, the potential use of automated guided vehicles and greatly improved task automation and efficiency, can be expanded.
