Creating this thread as I don’t see something specific to Tesla SCs and I have a question.

Plug and charge only works on V3 and V4, I believe. But can we still charge at a v2, we just have to do it via the app? Curious because I plugged into a B2 today, handshake started, then it said “charging stopped”. The SC shows as not compatible in the Lucid app, but I don’t know how accurate the app is…

The app is accurate re: compatibility.

Cribbing from @jered:
“…part of the NACS standardization was changing the signaling protocol between the EVSE and the vehicle from Tesla-proprietary to ISO 15118 (as used by CCS1). Older Superchargers only support the Tesla protocol while newer ones support both.

Older Tesla vehicles also only support the old protocol -- my 2019 X cannot use a CCS1-NACS adaptor (or a future NACS-plug at a third party charger) because it doesn't have a NACS port -- it has a Tesla Supercharger port which is physically the same but electrically different.”

So is this different on my 2018 MS 100D? I had a charger mod done on the car by Tesla ( mobil service) and it came with the CCS > Tesla charge port adapter.

I have absolutely no idea.

I'm not sure what you're asking exactly -- any Tesla can charge at any Supercharger. Only 2020+ models (or older with a charge controller upgrade, like you had) can charge with a CCS adapter or non-Tesla NACS (like ChargePoint's newer units).

Lucid will be the other way around -- Gravity can charge at any CCS charger (with adapter) and any non-Tesla NACS, but only at newer Superchargers.

My 2018 Model 3 charges fine with my home CCS from GE that I got for my 2013 Leaf. With an adaptor of course, and slow.

Home non-NACS AC chargers are J1772 connectors, which communicate with analog signalling in a way compatible with NACS-connector AC chargers. CCS builds on J1772 by reusing the communications (but not power) pins and adding the two big DC pins. Regardless, my comment above about Tesla/Lucid/CCS/NACS/etc applies to DC Fast Charging only.
 
There is no such thing as home CCS, CCS is a DC charging standard (50kW+).
I think the Tesla connector uses J1772 signaling for AC charging. With a Tesla to J1772 adapter I can charge my parent's Bolt from my Tesla Wall Connector.
As @jered says the 2018 Model 3 does not support CCS or NACS. I had to pay to have it upgraded.
The important point is that NACS is not the same as the proprietary Tesla standard, it's CCS signaling using the Tesla physical connector.

2018 Model 3:
AC: J1772 with Tesla connector.
DC: Only Tesla proprietary.

~2020+ Model 3:
DC: Tesla proprietary, NACS, and CCS (with adapter)

Gravity
DC: NACS and CCS (with adapter)
Can't charge on older Superchargers because they do not support NACS.

Ahhh, I was mixed up. Thanks
 
It's easy to identify older Tesla chargers from their post labeling. The posts are labeled 1A,1B,2A,2B, etc. None of these will be compatible with Non-Teslas. There are also 72kW Urban Superchargers that look nothing like the others. These are also not going to be compatible (AFAIK).

Posts labeled 1A,1B,1C,1D,2A... Are V3. Most of these are NACS compliant and can be used. But some are still reserved for Tesla only.
