Honda to test charging electric vehicles while driving in 2027 — InsideEVs

Honda plans to begin testing wireless charging technology for electric vehicles while driving on a highway in Chiba Prefecture near Tokyo, Japan, in 2027. As InsideEVs reports, at the first stage the company will equip a 300-meter section of road with the necessary infrastructure.

Power of up to 150 kW

Equipment embedded in the road surface is expected to wirelessly transmit up to 150 kW of electricity to vehicles. The system is designed to work with transport moving at 75 miles per hour, or approximately 121 km/h.

The technology was developed by Honda's research division jointly with Japanese company Taisei. Honda calls the planned project a demonstration test intended to verify the system's operation on a public road.

A test for commercial transport

The first test is aimed at assessing the technology for commercial transport—large trucks and passenger vehicles that are used intensively and require constant operational readiness. Honda noted that the system can work with both passenger cars and large trucks.

Honda R&D chief engineer Taku Ueda told Nikkei Asia that charging while driving could potentially make it possible to reduce the number of battery cells in future electric vehicles. According to him, this could reduce the weight and cost of batteries. Similar projects have already been explored by other automakers and government bodies; in particular, Electreon equipped a short section of road for wireless charging in Detroit.
