For DC charging, communication between the EV and EVSE
shall be power line communication over the control pilot line
as depicted in DIN 70121.

- bryanlarsen 3y agoHmmm, we need a good name for the older Tesla plugs that aren't NACS compliant. When I said "current NACS", that's what I was referring to. I should have been more explicit. Tesla vehicles built before ~2020 do not and can not speak CCS without a retrofit.
- _ea1k 3y agoArguably, those are !NACS at all. It wasn't called NACS until the specs were delivered, along with the requirement to support CCS signaling.
- mavhc 3y agoYeah, October 2020 is the time they started adding CCS compatible ECU. Surprised it's not a software update, it's just a new protocol. Is there a voltage difference? Or is the ECU 3rd party? At least with Tesla's exponential sales the number of people it affects will be smaller. 1 million out of 4 million I think
- _ea1k 3y agoYeah, there's a different controller inside the charge port. From what I've seen, it isn't a difficult upgrade and the part is unrestricted. I've been estimating the % of affected cars as ~20% at this point and the % that is capable is steadily increasing. Still an annoyance if you have one of the vehicles without support, but they are no worse off than before. The supercharger network has roughly doubled since then too.
