> Tesla chargers are CCS.

This is misleading and not entirely true.

Older Tesla chargers did not use CCS to communicate. My 2019 Model 3 doesn't support CCS at all. When I plug into a Supercharger, it's not using CCS to communicate with the charger, it's using Tesla's proprietary CAN bus protocol. Teslas made before 2021 need an ECU retrofit to support CCS.

    Pretty much all the old Teslas in Norway have been retrofitted to allow them to connect to CCS only chargers as far as I can tell. Had mine (2015 S 70D) done years ago when it became clear that future Tesla chargers would be CCS only.

    Almost no Teslas were manufactured pre-2019 vs post-2019.

      I think between 15 and 20% were build pre-2019. The number of non-CCS is actually on the higher end of this, as component shortages caused quite a few to be built without CCS support in 2020.

        Can confirm. My 2020 MX does not have CCS capabilities.

        OK, so less than 20%. In five years it’ll probably be closer to <5-10%.
