Besides, the car and the charging network have to work closely together, especially because of preheating and so on. Does anyone else offer that besides Tesla?
Huh? Are there cars that don’t do that? Either as part of the charging plan a preconditioning is done to match arrival at the station, or (as with VW) you initiate it manually (for example, not possible with Audi – I looked at the new A6 Avant E-Tron as an alternative to the ID7).
Then you have to commit to another bigger provider to have reasonably good prices.
Yes, Tesla is a bit cheaper for Tesla users. But what’s stopping you from using cards from two or three third-party providers?
P.S. Tesla charging stations are no longer an option for me and more and more users, by the way, since these are only designed for the 400V architecture. With 800V cars, you get around 100 kW charging power instead of up to (currently) triple that at third-party stations. That simply makes charging take too long for me (for example, with the A6).
