Infinite battery? The “Arena of the Future” charges electric vehicles by induction

Written by admin

It’s every tram driver’s dream: a car with (almost) infinite autonomy, which does not involve many stops and unforeseen battery problems. This new “Arena of the Future” is aptly named and could be the first step into the future of electric charging.

This arena of the future was developed by A35 Brebemi, in collaboration with Stellantis.

A few days ago, the Stellantide showed the world a project he has been working on for a few months: the “Arena of The Future”. The demonstration of DWPT (Dynamic Wireless Power Transfer) technology for wirelessly charging electric vehicles while traveling on specially equipped roads took place in Chiari, Italy, at the wheel of the new electric FIAT 500.

according to a Press release delivered by Stellantis, the DWPT is a coil system placed under asphalt. It transfers power directly to cars, trucks and buses, without having to stop at charging stations to ensure the battery is topped up.

According to the same press release, this technology aims to "simplify the customer approach to electric mobility" and, in addition, respond to the decarbonization of the mobility sector.

Our long-term strategic plan, Dare Forward 2030, is based on the principle of providing "edge mobility freedom" to all and this project is the essence of our journey as a company.

Said Anne-Lise RichardHead of Stellantis Global E-Mobility Business Unit.

Routes that guarantee an (almost) infinite battery

Collaborating with Stellantis means A35 Brebemi, a company owned by global transport infrastructure operator Aleatica, specializing in sustainable and innovative mobility solutions. Together, the two companies have developed a technology that can be adapted to any electric vehicle, provided that it is equipped with a specific receiver guaranteeing the transfer of energy from the road infrastructure to the electric motor. Thus, the drivers see the autonomy of their vehicle increased and the battery of the tram preserved.

By working with this amazing group of partners, we've proven that inductive charging technology can power our electrified future.

These joint projects are exciting steps in the work to extend battery life, reduce vehicle range anxiety, greater fuel efficiency, smaller batteries, remarkable performance and at reduced weight and cost.

Explains Anne-Lise Richard.

Encouraging findings for the future of electric charging

Tests carried out by the companies show that "the efficiency of the energy flow from the asphalt to the vehicle is comparable to the characteristic efficiency of fast charging stations, which is why the driver does not need s 'stop to recharge', reveals the press of Stellantis. to release. .

In addition, the electric FIAT 500 has shown that it is possible to drive at typical highway speeds without consuming the energy stored in the battery. This conclusion corroborates what Anne-Lise Richard said, since it is thus possible to save the battery of trams.

Referenced by Stellantis, this "Arena of the Future" is powered by direct current, guaranteeing many advantages:

  • Reduce power losses in the power distribution process;
  • Ensure direct integration with renewable energy sources;
  • Allow the use of thinner cables than AC power distribution with obvious advantages in terms of packaging, weight and occurrence of harmonic current;
  • Use aluminum cables for power distribution, which are easier to obtain and cost half the cost of copper, in addition to being lighter and easier to recycle in a circular economy business model.

For Times magazine, the inductive charging system, on which Stellantis and its partners worked to create the "Arena of the Future", is among the 100 most important inventions of 2021.
