Honda develops wireless charging technology for EVs in motion

Honda is developing Dynamic Wireless Power Transfer (DWPT) technology designed to charge electric vehicles wirelessly while they are in motion. Working alongside the Taisei Group and Taisei Rotec, the Japanese automaker aims to integrate transmitters into the road surface that generate a magnetic field, which is then captured by a receiver installed under the vehicle.

The system is being designed for compatibility with existing infrastructure, allowing modules to be installed after milling the road without requiring a complete reconstruction. The structure is also engineered to withstand the weight of heavy vehicles up to approximately 20 tonnes.

Initial development focuses on commercial fleets to test operational savings and efficiency. Honda intends to increase charging output to up to 150 kW, even at high speeds. The company plans to build a test road later this year, with public road testing in Japan scheduled to begin in 2027.
