This Fiat 500 no longer needs recharging

We know the principle of induction charging for smartphones. Why not adapt this technology to the motors of electric vehicles? Stellantis tried the experiment, and it works!

A specially equipped Fiat 500 drove at high speed on the “Arena del Futuro” circuit without draining its battery. The track, based near Chiari in Italy, is powered by direct current. The technology developed by Stellantis and its partners transmits energy from the asphalt to the car, in the same way as a Qi mat to a smartphone.

From the asphalt to the engine

The driver therefore no longer has to stop to recharge his car, nor does he have to fear repercussions on his health: measurements of the intensity of the magnetic field prove that it has no impact on the driver and his passengers.

The technology in question is called DWPT (for “Dynamic Wireless Power Transfer”), which consists of placing loops under the asphalt. It “wirelessly” charges electric vehicles traveling on dedicated and specially equipped roads. The DWPT system can be adapted to all vehicles (passenger cars, trucks, buses, etc.) equipped with a specific receiver transferring energy from the road infrastructure directly to the electric motor.

This is another of the particularities of this system, which therefore does not recharge the battery but supplies the motor directly. In this way, this prolongs the range while maintaining the charge of the vehicle battery, which must be spared by limiting the number of recharging cycles.

Obviously, if this test is encouraging, the cost to equip all road infrastructures with electric coils under the asphalt would be absolutely prohibitive. Nevertheless, this technology can be interesting for sections on the highway or for public transport that make the same journeys.
