Honda to Test Wireless Charging for Electric Vehicles

Honda Motor is set to trial technology that allows for the wireless charging of electric vehicles (EVs)—yes, even larger commercial trucks—while they’re on the go.

The automaker’s research and development arm, Honda R&D, teamed up with construction firms Taisei Corporation and Taisei Rotec Corporation to create this innovative technology. This announcement came out on a recent Monday.

The system works by utilizing power-transmitting units integrated into the roadway, along with a receiver placed on the vehicle itself. Essentially, this enables the transfer of electricity without any physical connection as the vehicle moves.

This could mean fewer stops for EV drivers at charging stations or charging at home, which sounds pretty convenient, right? Honda’s initial focus is on making this technology practical for the logistics and transportation industries.

Stronger-Than-Expected Quarterly Deliveries

The collaboration among the three companies has been ongoing since 2025, and they’ve already conducted tests on a dedicated private roadway.

Part of their efforts includes developing specialized pavement and charging equipment that can support heavy commercial vehicles, roughly weighing around 20 tons.

Further testing is slated to kick off in late 2026, specifically at a Taisei Group facility. They’ll assess durability, the performance of wireless power transfer, and strategies to minimize electromagnetic field leakage.

Future phases of testing will also look into delivering power outputs of up to 150 kilowatts, which could potentially support large commercial vehicles. Understanding how reliable this technology is at higher speeds will be crucial.

Honda, along with Taisei and Taisei Rotec, plans to participate in public demonstrations starting in the 2027 fiscal year, which begins on April 1, 2027.

This initiative will be part of what’s called the “Tateyama Project,” spearheaded by East Nippon Expressway Company on the Tateyama Expressway located in Chiba, Japan.

Since 2021, Honda has been exploring dynamic wireless power transfer technology as a component of its broader strategy to improve EV charging infrastructure.

However, the cost-effectiveness of installing wireless charging systems in roads remains an unanswered question. A Honda engineer expressed hesitation when asked about cost comparisons to traditional high-speed charging networks, indicating that a thorough economic evaluation would be necessary.
