Roads are beginning to become part of the charging network, with wireless systems allowing electric vehicles to receive power while they drive.
Imagine driving an electric car on a highway and charging the battery without stopping at a charging station. It sounds futuristic, but engineers are already testing roads that can transfer electricity to vehicles while they move. The idea is known as dynamic wireless charging. Charging equipment is installed beneath or within the road, while a receiver fitted to the vehicle collects the electricity as it passes over the charging section.
Several countries are now testing the technology, including the United States, France and Sweden.
How Can a Road Charge a Moving Car?
The basic idea is similar to a wireless phone charger, but designed for vehicles.
Charging coils installed beneath the road create an electromagnetic field. A compatible vehicle passes over the coils and receives electricity through a receiver installed underneath the vehicle. Only selected sections of the road need to contain the charging equipment. This means a vehicle could potentially receive power while travelling rather than stopping for a long charging session.
There are also other electric-road designs, including systems that use physical rails or overhead equipment. Wireless charging is particularly interesting because there are no exposed cables or charging arms on the road.
This Is Already Happening
This is not simply a laboratory experiment.
Michigan’s Department of Transportation says the nation’s first wireless-charging public roadway became operational in Detroit in November 2023. The road was built as a real-world demonstration of charging vehicles while they drive. In Europe, projects are moving further.
Electreon is developing a wireless electric road on France’s A10, designed to demonstrate charging for vehicles including heavy-duty trucks. The company says its system has demonstrated charging at highway speeds.
Sweden is also developing electric road technology, with projects aimed particularly at long-distance and heavy transport. These projects are important because trucks are among the hardest vehicles to electrify using conventional charging alone.
Why Not Just Build More Charging Stations?
That is the obvious question.
Traditional EV charging requires the vehicle to stop and connect to a charger. For everyday cars, that can be manageable. For long distance trucks, buses and high-mileage vehicles, it can be more complicated. A charging road could allow vehicles to top up while travelling, potentially reducing the need for very large batteries or long charging stops.
A smaller battery could also mean a lighter vehicle, although the actual benefits depend on the cost, power and coverage of the charging infrastructure. That is why electric-road projects are particularly interested in commercial transport.
The Biggest Challenge Is the Road Itself
Putting charging technology into roads sounds simple until you consider the scale.
Roads experience rain, snow, heat, heavy trucks, road repairs and constant traffic. Any electrical equipment installed underneath them has to survive those conditions while remaining safe and reliable. There is also the question of efficiency.
The vehicle needs to receive enough energy from the road to make the system worthwhile. Wireless power transfer can lose energy during transmission, and the alignment between the vehicle’s receiver and the charging equipment can affect performance. Research continues to examine these technical limitations. Then comes the biggest question:
Who pays to rebuild the roads?
It Would Be Expensive to Electrify Every Road
Nobody is suggesting that every road suddenly needs wireless charging.
The more realistic approach is to electrify specific high-traffic routes, particularly highways used heavily by electric trucks and buses. France, for example, has considered electric-road systems as part of longer-term freight electrification plans, but only a relatively small portion of its enormous road network would need such infrastructure.
This could create a future where normal roads and charging roads exist together.
A truck might leave a depot with a charged battery, travel onto an electrified highway and receive additional power along the route before reaching its destination.
What Happens to Charging Stations?
Wireless roads probably would not eliminate charging stations. Instead, the two technologies could work together. Charging stations would still be useful for homes, parking areas, destinations and roads without charging infrastructure.
Dynamic charging could handle vehicles while they are moving. That combination could make EV infrastructure more flexible.
The idea is similar to adding another layer to the charging network rather than replacing everything that already exists.
Could Cars Really Drive and Charge at the Same Time?
Yes, demonstrations have already shown that it is technically possible.
In 2025, Purdue University reported that a U.S. highway test wirelessly charged an electric heavy-duty truck while it travelled at highway speed. But proving that a vehicle can charge while moving is only the first step.
The harder challenge is making the technology cheap, reliable, efficient and widespread enough to justify rebuilding roads around it. That is why today’s projects are still pilots and demonstrations rather than a replacement for conventional charging.
The Road Could Become Part of the Vehicle
For more than a century, roads have mainly been passive infrastructure. They provide a surface for vehicles to travel on. Electric-road technology could change that.
A future highway could potentially provide transport, communication, sensing and electricity at the same time. That would turn the road from something vehicles simply travel across into part of the energy system supporting them. The technology still has major economic and engineering challenges, but the first demonstrations show that the basic idea works.
The future of EV charging may not always be a place where you stop.
It could be a road you drive on.
