Honda to Test Roadside Inductive EV Charging on Japanese Highways






While Honda's electric vehicle (EV) ambitions in North America faced setbacks due to tariffs and market volatility, leading to the cancellation of three new EV models, the company is actively exploring pioneering EV solutions within its home country of Japan. One such endeavor is the established Mobile Power Pack, a portable 22-pound battery system designed for electric scooters, which can be effortlessly exchanged at specialized charging and vending stations. This practical innovation, reflecting Honda's roots in two-wheeled mobility and Japan's urban landscape favoring compact vehicles, has been operational for several years.
Addressing the more complex challenge of charging four-wheeled EVs, Honda, in collaboration with Taisei Corporation, is transforming what was once a futuristic concept into reality: dynamic inductive charging for electric vehicles on public roads. Beginning early next year, real-world durability and feasibility tests will commence on a section of the Tateyama Expressway located east of Tokyo. This advanced charging infrastructure will feature a network of inverters embedded directly into the driving lanes, powered by conventional DC supply stations situated alongside the road. Vehicles equipped with compatible receiving panels on their undercarriage will be able to replenish their batteries while in transit, with target charging rates reaching up to 150 kWh for larger commercial vehicles.
A key advancement in this project is the integration of simplified wiring within the road-embedded units, combining the inverter and charging coil into a single, highly durable pad. The rigorous testing phase is designed to demonstrate that the initial investment in this infrastructure will be offset by minimal long-term maintenance, with plans to subject the surface to millions of vehicle passes. While widespread adoption of on-the-go charging roads in places like the United States may be a distant prospect due to differing road maintenance standards and the potential for electrical hazards from potholes, the successful validation of this concept holds significant promise for commercial applications. Particularly for scenarios involving continuous-operation cargo shuttles in environments such as busy ports, stretches of inductively charged road could ensure uninterrupted vehicle operation. Meanwhile, Honda's broader North American electrification strategy appears to be in a temporary holding pattern.
This pioneering venture into dynamic inductive charging by Honda and Taisei Corporation represents a significant stride towards a more sustainable and convenient electric future. By confronting the practical challenges of EV infrastructure head-on, they are not only advancing technological boundaries but also inspiring a global conversation about innovative energy solutions. Their commitment to rigorous testing and long-term viability underscores a dedication to progress that benefits both industry and society, paving the way for a world where electric vehicles seamlessly integrate into our daily lives, reducing range anxiety and promoting environmental stewardship.
