They use battery banks, so the system can charge slowly without overloading the grid and charge the car quickly. But the user will pay more for charging that fast. I’d expect to have much more slower chargers and few of the fast chargers. Most supermarkets these days have a charger, so if you’re not in a rush you can just shop and charge.
Was about to comment exactly this. Capacitors just can’t store the joules needed in any reasonable amount. There is some conversion loss but lithium batteries usually have a 95% or better cycle efficiency.
