The NACS adapter to use the supercharger network is here

[ChadS]

EXACTLY! My R1T got fried using a Lectron adapter on my Tesla wall charger. Luckily Rivian fixed it, but would again if I continued to use the adapter, so I had to buy another charger. 3rd party solutions are a bad idea unless it is approved by the manufacturer.

That is interesting, I use the Lectron. I have only used a Tesla L2 charger on occasion with the adapter, but frying the Rivian sounds like a bad option. Did Rivian point you to an adapter to use, or did they recommend just avoiding the Tesla L2 adapters altogether.

Magic docks are limited to 350A, which is 150kw at 400V. FYI, the old V2 Superchargers were limited to 150kw and did not have cable cooling. V3 went to 250kw and added liquid cooling.

It is doubtful the 350A limit will go away.

Are the Superchargers limited to 400V? Rivian's battery actually charges a little higher than 400. It's not a huge difference, but every little bit helps. Ideal would be the adapter supporting 500A, but I'm not sure that's realistic.

That’s not “some random dude”, he’s actually pretty well known and influential in the space.

Why only 300 amps? Magic docks are 150kw. I’d be willing to trust those vs some random dude on the internet.

“Older Teslas” like my 2021 model Y that doesn’t charge on CCS?

Our 2020 Y does. I’d be surprised if your 2021 doesn’t have the support too.

I think Rivian supports plug and charge since plugging in at a rivian station is automatic so everyone here should be good when the backend is sorted between Tesla and Rivian.

It supports plug and charge on EVgo now also where in older software it didn’t.

I can't find the reference at the moment, but I'm sure I saw a statement from Tesla saying they won't support 3rd party adapters for CCS on their Superchargers. The meaning, I gather, is if you use a non-supported adapter - one that isn't supplied by your automaker or by Tesla - you are solely responsible for any damage done to vehicles, charging equipment, etc. I'd wait to get an official adapter approved by Rivian, Tesla or whichever OEM made your vehicle.

I'm confused as to when people say CCS doesn't support plug & charge.

If you've ever used a RAN charger, you've experienced plug & charge over CCS....

I was at the Sacramento RAN charger earlier this summer and a guy in a Model S asked me how the charger worked for me, as he said it didn't for him. I had to explain to him that the Rivian fast chargers are for Rivian vehicles only and the two components talk to each other. I said for now, these chargers are only for Rivian's, much like superchargers are only for Tesla's.

I then pointed him to the destination chargers at the site and said those chargers are free Level 2 chargers and will charge at 11kWh.

I would guess, at some point, we will need one of these adapters to utilize one of the RAN chargers with an early version Rivian. As the new 2025 Rivians are equipped with the NACS outlets, the RAN plugs will become the NACS type. At some point, the Rivian Wall Chargers will be sold with the NACS plugs.

Currently limited to 500V. Tesla batteries are 450V, like Rivian.

300 amp is only 120 kw at 400v. Need at least a 500amp adapter.

I will only be using a Rivian official adapter. Too much at stake to take a risk on a 3rd party solution.

The domain was just registered in June of 2022. Something seems off to me... there is a thread over on the TMC forums. If they are working with the OEMs why are they on social media trying to promote the adapter?

In a pinch, I would take 120kw anyday. That more than I usually get out of EA chargers, when they work.

After testing my entire charging system, the tech determined the issue to be the adapter and told me to not use any adapter and to just get a J1772 charger. They said if I continued to use it, they wouldn't cover it under warranty, so I bought a Tesla J1772 wall charger and things are working great again. It would appear that many others use adapters and have not had any issues, but I'm not taking that chance again. I talked with the tech about this a lot as he was electrical engineer and use to work for Tesla, so he knew the chargers well. He even said to stay away from adapters, so I'll take his word for it. If an OEM comes out with one, then maybe I would try it, but I'm personally staying away from all 3rd party products as their usage will not be covered under any warranty.

This is about as close of a hint we’ve gotten on the max charge rate with an adapter. While he is just a 3rd party he did mention he was “working” with 4 OEMs, so I cant imagine he’d be building a 300 amp if they were thinking higher amps was an option. My assumption is 300 amps is the best we are ever going to get on our CCS cars at a Tesla SC. Better than nothing, but a little disappointing.

I agree. I won’t be surprised if Tesla limits adaptors to 300-350 amps on their SC network. I’m expecting Tesla to reserve higher amps for Tesla vehicles.

Indeed it's not on accident because 480V 3 phase is a common supply from transformers. Transformers can easily be adjusted up or down a bit depending on distance on the feed or demand. The "800V" cars would be supplied by 960V step down. Voltage boosting is inefficient but rectifying to DC of the same voltage is fairly lossless. Since intermediate supply is 13KV, there's lots of options. The variable KW delivery is done initially by constant current and varying the voltage to just above pack voltage and dialing back as the pack voltage comes up towards peak.

Of course 200kw would be better, but I'd be thrilled if I had access to a120 kw adapter. I'd even be fine with 50kw.

This weekend it took me 90 minutes and $15 to add 20% at the only functioning CCS stall between my house and my most frequent weekend getaway.

60 minutes waiting for the only stall to free up and 30 minutes charging at 50 kw

There were at least a dozen unoccupied NACS stalls nearby.
