Honda has partnered with Taisei and Taisei Rotec to develop a dynamic wireless power transfer system for electric vehicles. The technology utilizes a ground-based DC power source and transmission units embedded beneath the road surface, which deliver energy to a receiver mounted on the vehicle's undercarriage while it is in motion.
The company plans to begin testing on a specialized road segment by late 2026. The trials will evaluate energy transfer efficiency, electromagnetic leakage, and equipment durability. Engineers will conduct load tests equivalent to one million wheel passes at a 49 kN load to assess the structural integrity of the road, while also testing power transmission capabilities up to 150 kW at high speeds.
Honda is targeting the logistics and freight sectors as primary use cases to extend the range of electric trucks. However, the company has not yet disclosed specific efficiency metrics or energy delivery rates. Economic viability remains uncertain, as the system requires both vehicle-side hardware and significant infrastructure investment, with costs for installation and maintenance yet to be determined.
Other global initiatives have explored similar concepts, including a 1.5 km test track in France that achieved peak power exceeding 300 kW, as well as projects in Detroit and Italy. Honda has not provided a timeline for commercial deployment, noting that further real-world testing is required following the upcoming trials.
