Honda Motor Co.’s research and development arm, in partnership with Taisei Corp. and Taisei Rotec Corp., has developed “underlaying technology” that would enable wireless in-motion charging of electric vehicles.

The system is a combination of proprietary technology from each company, including receiver/transmitter units by Honda, a direct current power supply system by Taisei, and technology for embedding equipment in roads by Taisei Rotec.

The companies have been conducting research and development on the magnetic coupling wireless power transfer road system since last year. Part of their research has included experiments and validation testing on a test roadway at the Future Technology Field for Taisei Group/Satte.

According to Honda, the tests verified the effectiveness of the technologies “for a WPT system, road pavement structures, and road construction methods intended for use in demonstration testing on public roads with large commercial vehicles.”

Demonstration testing is scheduled to start April 1, the beggining of the Japanese 2027 fiscal year, and continue onward.

Honda said it's one step “toward the realization of a next-generation mobility society where people can enjoy the freedom of mobility while also reducing the environmental impact of mobility products and services.”

The automaker aims to reach carbon neutrality by 2050.

Honda isn't the only company working in the on-road EV charging space. Part of a Detroit street was electrified in 2023 through a partnership between the city and the state transportation department that tapped Israel-based company Electreon. The technology has also been employed in other parts of Asia and in Europe.
