Tesla's Supercharger Team was recently laid off. We discuss what this means for the company on today's TMC Podcast streaming live at 1PM PDT. You can watch on X or on YouTube where you can participate in the live chat.
Will 2025 equipped NACS vehicles be able to charge at Tesla Version 2 Superchargers
- Thread starter rrolsbe
- Start date
No, only V3+ Superchargers are opening up in North America (and not even all of those are open at this point). See Tesla's official Supercharger map and filter down to "Superchargers Open to NACS".
Note: it's not clear to what extent it's technically impossible to open up V2 stations vs Tesla making a business decision choosing not to. Regardless, so far it's clear they don't have much interest in opening up the V2s and I'd expect that trend to continue.

Might be useful to explain the reason. Originally, Tesla had their own internal protocol from car to chargers (v2 chargers at the time), call it Tesla protocol. V3 and later chargers speak both the ccs protocol and the Tesla protocol. Old tesla cars only spoke the tesla protocol, but starting a few years ago newer tesla cars could handle both Tesla and ccs protocol. That's why only an inert adapter was needed for those newer teslas to charge at ccs chargers.
All other cars than teslas ( all other ccs cars) can only speak ccs protocol, none of them can speak Tesla protocol.. Thus ccs cars can't charge at old Tesla chargers that only speak Tesla protocol (this is v2 chargers). Even when new cars (like say a rivian) start having a built in NACS port on the car, they will still only speak ccs protocol, so they can only charge at v3 and later Tesla superchargers.

My question that is sort of related to this topic:
Will the new 2025 other brand cars with NACS ports just work seamlessly with the existing Tesla mobile cables that I have? (And Tesla wall connectors?) I would expect probably? They would somehow negotiate down to using the J1772 protocol for level 2 over NACS plug, wouldn't they?

The J3400 spec doesn't include the CAN style comms that current wall connectors (and I think mobile connectors) use before falling back to J1772, so I expect they will use straight J1772 signalling.
The current crop of Tesla to J1772 adapters have logic to get the Tesla EVSE to fall back to J1772 signalling faster, although in the worst cases, you have to wait 30s or so until the EVSE does so on it's own. Some cars have problems with this, because they timeout before the EVSE starts using plain J1772.
I would think the new cars will get tested with current Tesla EVSEs and will work with them, although exactly how well is anyone's guess.

There are CCS2(same protocol as CCS1 with a better plug) cars charging on V2s here in Australia. So there is presumably an upgrade available. There have been some issues here with different CCS2 cars and Tesla chargers though not consistently. On the open chargers some will charge on V2 but not V3 and I think vice versa and some charge on both with no issue.
Also note that all Tesla superchargers here have attached CCS2 cables. There is no NACS, instead older V2s have a modified type 2 for legacy Teslas as well as a CCS2.
Thanks for all these additions over my partially correct descriptions of the v2 & v3 chargers. Glad to learn about these other details like the possible extensions for v2 chargers to have ccs and the other info.
More than anything I want to see widespread v4 chargers built out all across America, and fantasize about the old supercharger team coming back. I worry neither will happen. We have the "3.5" chargers (which to my understanding are v4 pedestals with v3 chargers in the backend). Has there ever been an explanation why the v4 chargers and v4 pedestals together aren't rolling out?

As far as I can tell, the hardware upgrades to the V3 are to allow plug and charge. Presumably the V3s already have the CCS hardware otherwise (so if using the app based authorization they would have worked).
As for V2 retrofits, anything is possible, just that it may not be worth it for Tesla to upgrade those.

Tesla had CCS2 / Modified Type 2 dual head superchargers for Europe since before V3 even existed:
Tesla confirms Model 3 is getting a CCS plug in Europe, adapter coming for Model S and Model X
But they don't have single head version of the V2 with CCS support, so while that's definitely technically possible, they simply don't have one manufactured for it, and it may not be worth it (especially since V2s involve the more rigid power splitting which may be a hassle to explain to non-Tesla users).
For V3, because it was released after CCS2 was adopted by Tesla, presumably it had native CCS support.
