There is a limit on the electricity grid as well.

kWh = V (110v) * current (A) * hours
with V=110, current=20A, it would take 5 hours to charge 10kWh, that's independent of battery technology.
If the grid can push current at 1000A for multiple cars simultaneously at the charging station, it would take only 6 minutes to charge 10kWh for each.
