France Tests Dynamic Wireless Charging on the A10 Motorway

France’s A10 is the world’s first highway where electric cars can charge while in motion

In a European first, a section of France’s A10 motorway, southwest of Paris, has been fitted with a dynamic inductive charging system that allows electric vehicles to charge while driving.

The groundbreaking pilot, known as “Charge as You Drive,” represents a significant step forward in the move toward large-scale transport electrification.

The 1.5-kilometre test stretch of road enables vehicles to draw power directly from the asphalt. Using inductive coils embedded beneath the surface, the system transmits energy magnetically to receiver coils installed under compatible vehicles—such as cars, buses, and trucks—allowing them to charge without stopping.

Developed by a consortium including VINCI Autoroutes, Electreon, VINCI Construction, Gustave Eiffel University, and Hutchinson, the system can deliver up to 300 kilowatts of power. Initial tests have recorded average outputs above 200 kilowatts, comparable to the latest fast-charging stations. Four prototype vehicles—a truck, van, car, and bus—are currently being trialled under real traffic conditions.

Rigorous technical assessments have already confirmed the system’s durability. Tests at the Road Research Center in Mérignac and long-term simulations at Gustave Eiffel University’s LAMES laboratory verified that the materials could withstand decades of wear. Following these results, the technology has now been approved for use on public roads.

Toward cheaper, greener EVs

If adopted more widely, dynamic charging could reduce the need for large, costly batteries in electric vehicles, lowering both purchase prices and the carbon footprint associated with battery production and recycling. Broader deployment could also accelerate EV adoption and help France cut transport emissions — with road traffic responsible for around 95% of the sector’s CO₂ output.

Charging access and billing

How drivers will pay for wireless charging is still being developed. Electreon has proposed a “charging-as-a-service”model, allowing users to pay per session or via subscription. The system automatically recognises authorised vehicles and activates energy transfer only when required. Pricing details are expected to be confirmed as the project progresses.

While in theory any electric vehicle can use the system, it currently requires installation of a receiver coil—either through retrofitting or integration during vehicle manufacture. The technology is not yet available commercially but is viewed as a potential cornerstone for next-generation EV infrastructure.
