And the “Tesla Connector” is not the Tesla connector in Europe, but Type 2 connection modified. Fully compatible with Type 2 charging.
And if you have, for example, a solar powered charge station, now your charge station needs a big inverter to make AC, which the car then goes about turning back into DC.
CCS is made for DC charging, but can fallback to Type 2 AC.
All EVs in Europe are CCS
