Load while driving

France experiments with dynamic charging

Op de bijzondere rijstrook kan een wagen laden terwijl hij blijft rijden.

France will soon start a pilot project on dynamic charging of electric vehicles. On a one-and-a-half kilometre stretch of the A10 motorway, they can charge their batteries while driving.

The experiment is a step in making freight transport more sustainable and should reduce dependence on large batteries and charging stations. It consists of a 1.5-kilometre stretch near Saint-Arnoult-en-Yvelines. Copper coils under the asphalt, fed by the electricity grid, generate a magnetic field there that is converted into electricity by receiving coils under vehicles. This allows electric trucks to keep running while charging, without stopping at a charging station.

Reducing battery size

Louis du Pasquier, director of sustainable mobility at Vinci Autoroutes, says this technology could halve or even reduce the battery size of vehicles by up to a third. In doing so, he stresses that it is not a technological gimmick. “At a power of 200 kilowatts, we can charge 50 per cent of a car’s battery by driving on the right-hand lane for 10 minutes.” In this way, not only does the charging requirement decrease, but also the need for large batteries and the consumption of critical resources.

The project is part of a wider collaboration between the French Ministry of Transport and Vinci Autoroutes, a major player in the construction and operation of French motorways. They are working with partners such as VINCI Construction, Electreon and Gustave Eiffel University. The first test runs of prototype vehicles will begin this spring. If they are successful, the door to large-scale implementation of this kind of Electric Road Systems (ERS) in Europe will be fully open.
