The Teslas in Europe are all going CCS, the Model 3 already comes CCS as standard and the rest can be upgraded https://www.electrive.com/2020/08/10/tesla-reduced-european-ccs-conversion-prices/
This is why you’ll see the Model 3 plugged in just about everywhere you find CCS and the Tesla V3 Superchargers are CCS only.
A few months back there was a big thing about thieving electricity from V3 Superchargers in non Tesla cars, for that to later be “fixed”, but I think Tesla wanted to see if it could read those cars info so that in future it could bring in a charge & billing system for non-Teslas in Europe, the same as Ionity does for non Ionity member manufacturers cars.
Tesla having changed to CCS (in Europe) & still able to identify Model 3 & bill them properly shows it can be done. Remember that Tesla costs about 23p/kWh and Ionity charges around the same for some of its members and 69p/kWh for non-members (Chargepoint card brings this down to 58p but still not as good as Maingau when that worked). This may not matter in areas with lots of different providers, but in remote areas it would make a lot of sense if charger providers could offer a deal with competitors vehicle owners.
