Let's do math!
Typical EV battery = 24 kWh
Energy rate to fill in 1 min = 24*60 = 1,440 kW
Assumed charging voltage = 400 V
Current = 3,600 A
I guess I'll need to spend more time lifting at the gym if I'm going to be able to handle that cord!
I will bet that EVs will not need to offer 3000 mph charging, like gas and diesel cars do.
90 kW fast chargers offer 300 mph charging, and this is all that is required. With a few minor adjustments in trip plans, 300 mph charging will match the endurance of almost all drivers, and it will be more grid friendly and less costly as well.

Would the Nikola Tesla Coil help here ?
To bad we haven't figured out how to harness lightning ( or create and capture it )

Yeah, that would only work with much higher voltage batteries. Say a 6kV battery, then the current drops to 240A. But then you need a 6kV certified connector and really good cable shielding
A 5 minute recharge and a 1000V battery might actually work. That is 288A.
Thankfully, DC doesn't need as big a cord as AC.

Seems like it's the old ACP system that Tesla originally used. Also, since charge time is limited by battery chemistry their claims are misleading.
