Honda has developed a dynamic wireless power transfer (DWPT) system designed to charge electric vehicles (EVs) while they are moving, potentially reducing reliance on conventional charging stations. The technology, developed over nearly five years, is being created in partnership with Japanese construction companies Taisei Corporation and Taisei Rotec.

The system uses three key components to transfer electricity wirelessly. A ground-based DC power supply feeds charging pads embedded beneath the road surface, which generate a magnetic field to transmit energy.

A receiver mounted underneath a compatible vehicle captures the electricity and directs it to the battery.

Honda initially plans to target logistics and transportation operations, where reducing charging downtime could offer significant benefits for commercial fleets and heavy-duty electric vehicles.

Testing is expected to begin by early 2027, with the partners planning to construct a dedicated test lane. Engineers will evaluate charging performance, electromagnetic safety and long-term durability under simulated traffic conditions, including approximately one million vehicle wheel passes.

Tests will also assess whether the system can deliver up to 150 kW while reliably charging vehicles travelling at higher speeds.

However, Honda is not the first company to explore wireless road charging. Similar projects have been tested across Europe.

The French government recently trialled embedded charging technology along a 0.9-mile motorway section near Paris. Initial tests reportedly achieved peak power transfer exceeding 300 kW for equipped trucks, vans, cars and buses.

While dynamic wireless charging could help reduce charging stops and improve EV fleet efficiency, challenges remain around infrastructure costs, vehicle compatibility and large-scale deployment. Honda has not yet announced a commercial launch timeline.
