Very much simplified, a 10 minute charge would mean 6C charging throughout the curve. 100 kWh battery would thus require 600 kW on average. Right now the most powerful MCS chargers deliver 1440 kW.

So not impossible, as long as the battery can handle the current. It's obvious that charging technology is not going to be the bottleneck.

(A real battery would probably have a charging curve that slows down towards the end, so more than 6C would be required in realistic conditions.)
