Honda to trial wireless charging for moving trucks on Japanese highway

Honda Motor announced that its research arm, Honda R&D, will join construction firms Taisei Corporation and Taisei Rotec Corporation to pilot dynamic wireless power transfer on a highway. The technology embeds power-transmitting units in the pavement and equips vehicles with receivers, allowing electricity to flow while the vehicle moves. After private-road tests since 2025, the trio will conduct further trials in late 2026 at a Taisei Group facility, focusing on durability, electromagnetic-field leakage and power output up to 150 kilowatts for trucks weighing around 20 tons.

The partners aim to demonstrate the system publicly on the Tateyama Expressway in Chiba during Japan's 2027 fiscal year, under the Tateyama Project led by East Nippon Expressway Company. Honda has pursued this dynamic charging concept since 2021, though the economic viability of road-installed chargers remains uncertain.
