On the A10 motorway, Vinci will install two sections to test the dynamic charging of electric trucks, by induction and by conductive rail.
The transport sector accounts for one third of France’s greenhouse gas emissions. A situation caused by the very many trucks on our roads for the transport of goods. Nearly 9 out of 10 goods pass by road! Even if the State is pushing for the development of rail freight, this share will remain in the majority for a long time.
It is therefore necessary to find solutions to improve the carbon footprint of heavy goods vehicles. One answer to the problem is of course electrification. But for such machines, you need XXL batteries, not to mention hyper-powerful charging points.
Hence the idea of developing dynamic charging, ie charging while driving. This type of system would allow electric trucks to have more reasonable batteries, which would limit their cost and the use of raw materials. A study by the Ministry of Transport (from 2021) suggests a saving equivalent to 10 to 17 electric car batteries per truck.
Dynamic charging is being tested in several countries, including Germany. And this will soon be the case in France, in real conditions on a motorway open to traffic. A consortium led by Vinci Autoroutes won the BPI France call for projects (State funding under the France 2030 plan).
The consortium will experiment on the A10 motorway with two test sections of two kilometers each, one for charging by induction and one for charging by conductive rail. The pilot site will be upstream of the Saint-Arnoult toll, in the direction of Paris Province. The project will be launched at the start of the 2023 school year, with tests on a closed Cerema track in Rouen and then installation on the A10.
Vinci then plans to equip longer sections for initial commercial use, with a gradual extension on the main axes used by heavy goods vehicles. But dynamic charging technologies can also be considered by other vehicles.
In the announcement of this project, Vinci reports that “deployed on a large scale, dynamic charging systems would make it possible to reduce CO2 emissions from road freight transport by 86% compared to the use of diesel, compared to 60% for with regard to heavy goods vehicles carrying very large batteries and recharging at terminals”.
