Well, Tesla developed its own standard, Europe restricted and standardized it to Type 2 connectors, and then CCS.
Tesla had to go along with that, but CCS has yet to support plug-and-charge, and it’s also its own app for Superchargers. Delivery and shipping didn’t come until CCS 2.0.
Tesla now has its own sauce, all other manufacturers work with CCS, and for example, Ionity is a collaboration between:
- BMW (Mini, Rolls Royce)
- Daimler (Mercedes, Smart, Trucks)
- Ford (Lincoln)
- Volkswagen (Audi, Bentley, Bugatti, Lamborghini, Porsche, Seat, Cupra, Rove, Skoda)
- Hyundai (Kia, Genesis)
So you can blame “the rest”, but you can also blame Tesla for not cooperating with standards, because they want to go faster. There is something to be said for both of them.
The technical standard is now available for vehicle/charging station connections, but the payment infrastructure is not yet in place. At Tesla you now have one company that designs, installs, maintains and operates charging stations and arranges payments.
It makes sense that other companies are not aligned with this. The general charging infrastructure is more fragmented, and has a designer (eg ABB), a installer/supervisor (CPO, eg FastNed, Ionity, Allego) and a company that arranges payments (charge card, eg Shell Recharge).
It will take some time for everything to run smoothly. Fortunately, roaming is already going well with normal traffic, and I don’t expect it to take another 3 years before tethering and charging is implemented on all major networks.
