Probably not; however, that's based on some assumptions, and some things will change by the time those stations become available:I have a 2021 Tesla Model Y, which unfortunately is not CCS compatible. Without CCS retrofit (which is not available on Model Y yet), will I be able to charge the Tesla at non-Tesla NACS charging stations?
Interesting, my 2020 MY was CCS1 ready when it was delivered, so when the adapter became available from Tesla, I purchased one and tested it, it worked. May be during the pandemic and supply chain related issues, Tesla may have stopped adding the CCS1 option on the newer MY as a temporary measure so that they could still ship their Model Y w/o waiting for CCS1 parts.I have a 2021 Tesla Model Y, which unfortunately is not CCS compatible.

That's precisely correct. The history is this:Interesting, my 2020 MY was CCS1 ready when it was delivered, so when the adapter became available from Tesla, I purchased one and tested it, it worked.

I have a 2022 Model 3 RWD with NACS port. I am able to do CCS2 charging at non-Tesla’s supercharger with Adaptors, except for Tesla’s V3 CCS2 superchargers.That's precisely correct. The history is this:
If you have the oldest version (as I do on my 2019 Model 3), Tesla's upgrade will most likely require another variant of the 1537264-00-B ECU. This is because the pinout of this ECU differs from that used on the older cars, and because Tesla changed the thermistors used to measure the temperatures of charging components, so the new ECU will need to interpret those values correctly, which the 1537264-00-B ECU does not do if it's plugged in directly. It can be made to work, as described in the thread I referred to earlier, but it's a kind of hackish procedure.
- The oldest vehicles (like my 2019 Model 3) have an older charging electronic control unit (ECU; whose part number I don't know offhand). These will need an upgrade to a new part that is, AFAIK, not yet available from Tesla. I'm not sure if any Model Ys shipped with this configuration.
- Around the time the Model Y was introduced, Tesla redesigned their charging system to include CCS compatibility. This was presumably done partly for the European market, but yet another charging ECU variant is included in European-spec Model 3s and Ys. Anyhow, the new North American-spec ECU, 1537264-00-B, includes CCS support as well as support for Tesla's proprietary protocol. When it was first introduced, though, Tesla did not advertise CCS compatibility in the US.
- Because of the chip shortage, Tesla temporarily dropped the chips needed to "speak" CCS with the 1537264-80-B ECU, which is a drop-in replacement for the 1537264-00-B ECU. I believe this was done at least twice, for brief production runs in both 2021 and 2022, IIRC. Tesla could do this quietly and few people noticed because Tesla was not advertising CCS protocol compatibility in the US.
If you have the "lobotomized" 1537264-80-B ECU, you can literally unplug it, unbolt it from the car, and install the full -00- variant and it will work. (You'll need to do a software update or re-install, too, so that the car knows what you've got.) Tesla could be offering these upgrades today, assuming they have sufficient supply of the -00- ECUs. It's possible they aren't yet offering the upgrades because they're still suffering from chip shortages; or maybe they want to have supplies of both the 1537264-00-B ECU and whatever new variant the oldest Model 3s will need so that they can open the floodgates for all Model 3 and Model Y owners simultaneously. It's also likely that CCS upgrades for older vehicles are just not a priority for them, although they are offering upgrades for the Model S and Model X. Those cars have their own charging ECU variants, so they require different upgrade ECUs than the Model 3 and Model Y need.
Yes, Correct.Probably.
You have an NACS Tesla in a region that uses CCS-2? Just making sure I'm understanding correctly.
