What's the difference between "Tesla's charging standard" and NACS? The Tesla website calls their Supercharger NACS: https://www.tesla.com/NACS
Older Teslas can't charge on these chargers because they don't have CCS support. Those cars will need to get a CCS retrofit.
In general you shouldn't take anything Tesla says at face value. Lying is just too much a part of the company culture at Tesla.
Tesla lies about things as dumb as quarter mile stunts. There was absolutely no need to lie about it, yet they just couldn't help themselves and they went ahead and lied about it anyway:

Tesla never even ran the quarter mile. And the worst thing about it is the Cybertruck's lead engineer trying to rationalize the lie:

When your engineers lack commitment to basic honesty then you've got a sick company culture.
When you said "these chargers," do you mean the V3 Superchargers with CCS+J3400? Or, do you mean NACS 3rd party charging stations?
No other chargers will support Tesla's protocol. They'll all be CCS.
For example, Teslas in Europe since the Model 3 have had CCS support. The older European Model Ss and Model Xs needed to get CCS retrofits.
The newer North American Teslas have CCS support. The older ones need the retrofit.
Why? I would say the plug matters more than everything else combined. The bits on the wire do basically the same thing across standards and translation isn't very onerous. The plugs vary significantly in what amps and volts they support, and because of heating it's hard to even have an adapter if you want max charging speed.
Yes older Teslas will need a retrofit. That's not too difficult.
If your car talks CCS you can at least use an adapter if you don't have the right inlet. But if your car doesn't talk CCS then it can't charge at all.
But adapting plugs is a lot more limited than adapting protocols. And you can get a permanent protocol install that has no downsides, while there's no fully-featured way to support multiple high-wattage plugs.
No, the adapters are dumb adapters that just connect the pins. The plug is separate from the protocol.
An adapter that would also do protocol conversion is bigger, clumsier, and more expensive.
Doing both at once is more expensive than a dumb adapter but that difference doesn't even need to be $5, and it does not need to be bigger.
Here is a real world example of a dumb adapter for J3400 to CCS Type 1 combo. It does no protocol conversion. It's smaller, simpler, and works: https://www.youtube.com/watch?v=Y3-0xRTduPI
Just accept the practical reality that Tesla's protocol is dead. CCS is the protocol going forward. CCS won.
It's big because it's going from the bigger plug to the smaller plug. A dumb adapter would be the same size. And it's very much not an example of a pure protocol converter that isn't changing plugs.
It's finicky because it's a prototype.

What makes you think I don't accept this? What does this have to do with anything I've said?
No. Here is Tesla's CCS to J3400 dumb adapter. It is smaller, simpler, and works: https://shop.tesla.com/product/ccs-combo-1-adapter?web=true
> What makes you think I don't accept this?
Everything you have said up to this point.
There is no technical reason the adapter in the video wasn't this size (assuming it supports the same current). Adding a chip does not require it to be bigger than this. I don't know why that one was bigger, but it wasn't the active/passive distinction.
> Everything you have said up to this point.
How so? Do you think I'm arguing this because I'm a Tesla fanboy and want the win to go to them? I assure you that's not the case. I just think plug matters more than protocol as a general statement for EV charging.
Please explain how CCS being a definitive winner affects a single thing I have said.
Here's a CCS to CHAdeMO adapter. It's big, clumsy, and expensive: https://evniculus.eu/products/adapter-ccs2-to-chademo-for-ni...
NACS is the Tesla connector. Tesla will support both its homemade protocol on that connector (at the moment far superior because it doesn't require separate payment, you just plug in and charge) and CCS. Other stations will support CCS for fast charging.
This only matters when you want to level 3 charge, i.e, supercharge. Level 2 chargers always work without CCS support because that's just a normal J1772 which was always pin-compatible with NACS (you get a simple plastic adapter with the car).
All Teslas 2021 and newer support CCS. It costs about $250-300 to upgrade an older Tesla to support CCS. Tesla already has upgrade programs in place for some models; you can just schedule it from the app. If you really need support for models that they haven't yet covered, 3rd parties have been offering this upgrade for a long time at the same prices.
There's nothing special here. No one is lying. I have no idea what you're talking about. Sounds like you have some problem with Tesla?
