Yes, everyone except Tesla was using CCS. They still are, but might switch by 2025 or whatever. I suspect they’ll have both connectors for awhile, similar to have some DCFC had a CCS and Chademo.
* Nissan leafs still stubbornly only use Chademo for fast charging. Even for the 2024 model!
* Before the CCS1 -> NACS adapter that Tesla made, the only option for Teslas to fast charge was to use the (very expensive) Chademo -> NACS adapter.
It is irrelevant and essentially does not matter or exist.
