I think the idea behind super-fast charging is that people drive to specialized charging stations rather than charging at home.
Building and maintaining vehicle storage (parking) is already expensive, and then add on the electric infrastructure for charging stations… Drivers will need to be sharing those spaces.
Fast chargers are already a thing. Those are used on road trips. For your wall box at home 11 KW are completely fine. All you need to do is get the battery full overnight. You don’t need huge charging speeds for that.
There definitely is. It’s still the worst aspect of owning an EV, especially if you don’t have your own charger. But I still would never ever want to drive an ICE car again.

Second, the intent of supercaps shouldn’t be range but batter loading. The limit of regenerative braking is not in the torque of the motor but what you need to do to transform the generated current into chemical energy in a battery. It’s not as simple as passing the current through a capacitor, but with supercaps it is. So with the supercaps you can dump extreme currents and either use the energy for taking off or redirect it to the battery.
I demonstrated this in my senior design project at uni and it worked well. Didn’t have a load I couldn’t absorb with a bunch of the caps. The issue was they’re very low voltage, so similar to the li-ion cells you need a lot of them in series to match the system voltage.

I don’t have an EV, and my experience trying to charge rentals has been miserable. There is a lot of room for improvement.
