The problem with charging an electric car in a short time is eliminating the heat generated during charging. And a large part of that heat is generated by the cables that power the car during the recharging time. The more amps run through the wires, the more they get hot.
In normal car chargers the power cords carry less than 60 amps, and in the more advanced and faster chargers on the order of 100 to 150 amps. And those fast-charging chargers take about 30 minutes to charge 80% of the power of an electric car battery.
At Purdue University they have developed a product (patent pending) that can charge an electric car in less than 5 minutes, cooling the cables that feed the car. In this way the cables can carry more than 2,000 amps and charge the battery in a few minutes.
The cables that carry the current are surrounded by a cooling agent that can change from a liquid to a gas and removes the heat generated in those cables. Doing it that way, smaller cables could be used to feed with a higher level of current
At Purdue University they have carried out tests feeding batteries with charging currents of up to 2,400 amps, but we must bear in mind that currents of the order of 1,000 amps are enough to have recharge times of less than 5 minutes, which is already comparable to what it takes today to fill a car with gasoline.

The idea seems very good to me and it can be a way to eliminate one of the limitations of electric cars. I hope that they will industrialize it as soon as possible and it will be a reality in the market as soon as possible.
We will all win.
