While EV battery makers prioritize ultra-fast charging, such as BYD’s 9-minute system, Honda is exploring wireless road charging technology.
The Japanese automaker has unveiled a wireless road charging system in collaboration with the Taisei Group, allowing EVs to charge while in motion. While similar concepts exist, Honda’s investment could accelerate the technology’s commercial viability and encourage broader industry adoption.
Honda’s system utilizes a high-power-density receiver and transmitter installed beneath the vehicle, which interacts with charging infrastructure embedded directly into the road surface. This system receives power from adjacent electrical control units. Although Honda has commenced practical testing of this technology, specific data regarding energy transfer rates or total battery charge capacity has not yet been disclosed.
It is unlikely that such wireless charging infrastructure will serve as a complete replacement for traditional charging methods in the near future. Honda acknowledges that this technology is intended to supplement existing solutions by reducing the frequency at which owners must rely on home or public charging stations.
Honda is targeting commercial vehicles first. By late 2024, it will partner with Taisei to test surface durability, eventually upgrading to 150 kW capacity. Aiming for carbon neutrality by 2050, Honda believes this tech will boost EV adoption, with public road trials in Japan scheduled for 2027.
