Infinite battery? “Future Arena” will charge electric vehicles by induction

It’s the dream of every tram driver. It’s a car with (almost) infinite autonomy, and it doesn’t stop on the battery multiple times or cause unexpected problems. This new “Future Arena” is not ashamed of its name and could be the first step towards the future of charging.

This futuristic arena was developed by A35 Brebemi in collaboration with Stellantis.


A few days ago, Stellantis showed the world the project "Arena of the Future" that they have been working on in the last few months. In Chiari, Italy, a demonstration of DWPT (Dynamic Wireless Power Transfer) technology was held to wirelessly charge an electric vehicle while driving on a specially equipped road, holding the handle of the new electric FIAT 500.

According to a press release issued by Stellantis, DWPT is a coil system placed under asphalt. Transfer energy directly to cars, trucks and buses without having to stop at a charging station to ensure that the battery is charged.

According to the same statement, the technology aims to "simplify customers' approach to electrical mobility" and to address the decarbonization of the mobility sector.

Our long-term strategic plan, Dare Forward 2030, is premised on providing "state-of-the-art mobility freedom" to everyone, and this project is the essence of our path as a company.

Anne-Lise Richard, Head of Global e-Mobility Business Unit at Stellantis, said.

Roads that guarantee a (nearly) infinite battery

Working with Stellantis is the A35 Brebemi, owned by global transportation infrastructure operator Aleatica, with a focus on sustainable and innovative mobility solutions. The two companies have jointly developed a technology that can be adapted to any electric vehicle as long as it has a specific receiver that guarantees the transfer of energy from the road infrastructure to the electric motor. In this way, the driver can see that his car's range has increased and that the tram's battery has been saved.

Working with this incredible group of partners, we have proven that inductive charging technology can drive our electrified future.

These collaborative projects are exciting steps in working to achieve longer battery life, less vehicle area anxiety, greater energy efficiency, smaller batteries, amazing performance, and lower weight and cost.

Ann Rize Richard explained.

The conclusion is promising for the future of charging

According to tests conducted by both companies, "the efficiency of energy flow from asphalt to the vehicle is comparable to the characteristic efficiency of fast charging stations, so drivers do not have to stop charging," the Stellantis press said. Has made it clear. release. ..

In addition, the Electric Fiat 500 shows that it can travel at normal highway speeds without consuming the energy stored in the battery. This conclusion supports what Anne-Lise Richard said because it is possible to save the tram battery.

As listed by Stellantis, this "future arena" is powered by direct current and guarantees a variety of benefits.

  • Reduces power loss in the energy distribution process.
  • Ensure direct integration with renewable energy sources.
  • It allows the use of cables thinner than AC current distribution and has obvious advantages in terms of packaging, weight, and generation of harmonic currents.
  • In addition to being lightweight and easy to recycle, the Circular Economy business model uses aluminum cables for power distribution, which is more affordable and half the cost of copper.

For The Times, the inductive charging system developed by Stellantis and its partners to create the "Arena of the Future" is one of the 100 most important inventions of 2021.
