- Round a mile of French freeway has been fitted with induction coils
- The small part is a testbed for vans, vans, vehicles and buses
- Sustained charging speeds of over 200kW have been reported
A small part of freeway simply exterior of Paris, France is at present appearing as a testbed for the following technology of dynamic vehicle charging, providing charging speeds of as much as 300kW with out the necessity for cumbersome wires and cables.
A part of the Cost as you Drive mission, which includes Electreon, Gustave Eiffel College and Vinci – a worldwide mobility infrastructure firm – the 1.5km (just below a mile) part of the A10 freeway has been fitted with induction coils beneath the floor, so these concerned within the mission can assess the efficiency of the induction charging system.
According to Vinci, the early results have been “very encouraging”, with more than 300kW of instantaneous power delivered and 200kW of average power delivered under optimal “steady-state” conditions.
The trials, which are taking place on highways that are open to the public, currently involve just one truck, a van, a car and a coach, all of which have been fitted with the appropriate receiver technology to wirelessly top up the onboard battery packs.
Vinci states that if deployed on a large scale, the inductive charging road surfaces could considerably reduce the weight of batteries in electric vehicles, as they wouldn’t need to be so large to offer the required range to get from A to B.
On the contrary, so long as the batteries offer enough range to travel to and from these stretches of highway, they could be drastically reduced – by “several tonnes in the case of heavy electric vehicles”, according to Vinci.
As a result, cost, carbon footprint and material footprint would also be cut, while eliminating charging stops and range limitations, both of which are expensive for fleet operators.
The French project is the only trial in the world currently operating on open highways, but it isn’t the first of its kind, with bus routes in Germany, taxi cabs in Sweden and heavy items automobiles within the US all present process comparable experiments to validate the know-how.
Analysis: Too good to be true?
Wireless EV charging isn’t exactly a new concept, with some of the first dynamic charging demonstrations taking place as early as 2010.
However, the technology has moved on to a point where it can now be introduced to public roads on a small scale.
Plus, Porsche has demonstrated that static wi-fi charging is usually a commercially viable providing, with an 11kW wireless charging pad now provided to clients of the upcoming Cayenne EV.
However rolling out a community of latest roads fitted with induction coils would show hideously costly and retrofitting infrastructure with the tech could be even worse, particularly contemplating the disruption it might trigger.
There’s additionally no phrase from Vinci on how pricey the bespoke wi-fi receivers have been to construct and match to an present EV, assuming they’d must be pretty particular to deal with the lofty charging speeds touted.
Fairly than ripping up the roads and putting in costly induction coils, some elements of the world have managed to decarbonize their public transport programs utilizing overhead cabling, both to energy trams or to fast-charge electrical buses each time they pull as much as a cease.
Vinci’s imaginative and prescient is to speed up the electrification of heavy obligation automobiles from the freight transport and logistics sector, which alone accounts for greater than 16% of France’s greenhouse fuel emissions, in response to Nicolas Notebaert, CEO of Concessions at Vinci.
If dynamic charging can scale back the vitality density required in vans, it may persuade fleet operators to make the swap. However convincing governments to foot the infrastructure invoice may very well be the most important problem.
