13.6.2022Arena del Futuro circuit charges EVs as they drive
Stellantis and its project partners, after months of testing at the “Arena del Futuro” circuit, have demonstrated the capability of Dynamic Wireless Power transfer (DWPT) technology to wirelessly recharge electric vehicles (EVs) as they travel over specially equipped road lanes.
DWPT is a system of coils positioned under the asphalt that transfers energy directly to cars, trucks and buses without the need to stop at charging points to refill the battery. The technology can be adapted for all vehicles equipped with a special “receiver” that transfers the energy incoming from the road infrastructure directly to the electric motor, extending the range, while conserving the vehicle battery charge.
The “Arena del Futuro” pilot project - in Chiari, Italy - of Stellantis and all partners involved is coordinated by A35 Brebemi, a company owned by the global transportation infrastructure operator Aleatica that focuses on sustainable and innovative mobility solutions.
Work at “Arena del Futuro” shows that a BEV, like the new Fiat 500 outfitted to test the system, can travel at typical highway speeds without consuming the energy stored in its battery. Tests are showing that the efficiency of the energy flow from the asphalt to the car is comparable to the typical efficiency of fast charging stations, so the driver does not need to stop to recharge. Furthermore, measurements on magnetic field intensity prove that there is no impact on the driver and passengers.
The “Arena del Futuro” itself is powered by direct current, which offers several advantages such as reducing the power losses in the energy distribution process, guaranteeing a direct integration with renewable energy sources without the need to convert DC into AC, and allowing the use of thinner cables than the AC current distribution with evident advantages in terms of packaging, weight and harmonic pollution.
“Our long-term strategic plan, Dare Forward 2030, is based on the premise of bringing ‘cutting-edge freedom of mobility’ to all and this project is the very essence of where we’re headed as a company,” said Anne-Lise Richard, Head of Global e-Mobility Business Unit, Stellantis.
“Working with this incredible group of partners, we have proven that inductive recharging technology can power our electrified future. These joint projects are exciting steps as we work to achieve longer battery lifespan, lower range anxiety, greater energy efficiency, smaller battery size, outstanding performance and lower weight and cost.”
