Honda Develops Wireless EV Charging for Highways, Tests Begin 2027

Honda R&D, Taisei Corporation, and Taisei Rotec announced October 5 they have developed core technology for wireless charging of electric vehicles while driving at highway speeds. The magnetic-field coupling system will be tested on Japan’s Tateyama Expressway starting in fiscal 2027 (April 2027 onward). The breakthrough targets logistics and transportation sectors, where continuous charging could eliminate frequent charging stops.

How the wireless charging system works

The system transmits power from road-embedded transmission units to vehicle-side receiving devices using magnetic-field coupling, with no physical contact required. Honda developed the high-power-density receiver and transmitter units compatible with DC power distribution. Taisei built the DC power supply system, while Taisei Rotec created the road-embedding construction methodology. The technology is designed to support maximum expressway speeds and accommodate large commercial vehicles weighing up to 20 tons.

Why this matters for EV adoption

Range anxiety and long charging times remain barriers to EV adoption in Japan. The wireless charging system could allow vehicles to charge while driving, reducing battery size requirements and eliminating stops for stationary charging on long routes. Honda engineer Taku Ueda stated the technology represents unprecedented value in mobility. By 2026 year-end, the companies will construct a test track at Taisei Group’s facility to evaluate long-term durability, charging performance, and electromagnetic safety.

Timeline and real-world testing

Honda has worked on dynamic wireless power transfer technology since 2021. The three companies will conduct demonstration testing on the Tateyama Expressway in Chiba Prefecture from fiscal 2027 onward. The system is designed with maximum output of 150 kW to support commercial logistics vehicles. Success in Japan could accelerate adoption globally as governments push EV infrastructure expansion.

Stock implications for Honda

Meyka grades Honda (HMC) a B with a 12-month price forecast of $27.71, suggesting limited upside from the current $31.78 price. The RSI stands at 43.86, indicating neutral momentum. While the wireless charging breakthrough is strategically important for Honda’s EV future, near-term financial impact remains uncertain as commercialization is years away. Investors should monitor fiscal 2027 test results for evidence of technical viability and market demand.

Final Thoughts

Honda’s wireless charging technology addresses a real EV pain point, but commercialization timelines extend beyond 2027. With Meyka grading the stock B and forecasting $27.71 annually, investors should treat this as a long-term strategic development rather than a near-term catalyst.
