Rapid charging speeds are getting faster all the time. There are already a few cars capable of 400kW, while BYD’s Flash Charging tech supplies a whopping 1,500kW. But even the latter system involves stopping, plugging in and waiting for about 10 minutes. Honda, meanwhile, is envisioning a future in which you won’t have to stop at all.

The Japanese manufacturer is working with The Taisei Corporation and its Taisei Rotec subsidiary on wireless, road surface-integrated charging technology that’s capable of keeping an electric car topped up as it drives along. This isn’t a new idea, but the Honda project stands out firstly because of the potential output of up to 150kW, intended to charge up the especially large batteries of electric commercial vehicles on the go.

Another notable aspect is a planned test on a public road from April 2027 onwards. The Tateyama Expressway in Chiba, Japan is the chosen site, although the assessment will be preceded by testing at the Taisei Group’s Future Technology Field in Fukushima Prefecture starting later this year.

Each of the three companies will provide one key piece of the puzzle. It’s Honda’s job to sort the power receiver and transmitter units, while Taisei is developing the DC power supply system, and Taisei Rotec will work on the technology necessary for sticking all of this into the asphalt.
