The price is not the only obstacle to the purchase of an electric car.

The availability of charging stations, like the time needed to recharge one's vehicle, can also fuel reluctance.

Ford appears to be well on its way to solving the second problem.

In collaboration with Purdue University, the American manufacturer has filed a patent for a cable that would charge a vehicle in just a few minutes,

Wednesday.

The two partners managed to get around the heating problem.

“The more current that passes through the cable, the dangerously hot it becomes.

This is why even the fastest of Tesla's Supercharger cables cannot display an intensity higher than 520 amps ”, we learn in a video published by the university.

"Less than five minutes" to charge a vehicle

The system that has been developed would speed up recharging by reducing the heat transmitted in the cable. “Using a liquid-vapor phase change, the cables could display up to 2,400 amps,” the video said. This cooling system would therefore be able to withstand an intensity four times greater than what currently exists. In an article published last June in

Science Direct

, the university had already indicated that "with the appropriate batteries and other auxiliary components, this technology should reduce the charging times of electric vehicles to less than five minutes".

It remains to design batteries capable of accepting high currents.

Ford specifies that "the fast charging cable will not be marketed for some time."

For his part, Issam Mudawar, professor of mechanical engineering at Purdue University, allows himself two years to test this technology.

Ford also plans to improve on-board systems in its electric vehicles to be ready to accommodate super-fast charging.
