Using Tesla wall charger with the Rivian?

[bjcleaver]

I have a Tesla Wall Connector with Lectron adaptor but the first time I plug it in, the R1T tries to maybe lock the charger? I hear it do something and then get a red ring indicating a fault. If I unplug and plug it back in, it goes to blue. Anyone else seeing this? It charges fine every night but it's annoying I have to do this everytime I plug it in.

I have the same setup. When I plug it in it clicks and turns red for a few seconds. Seems like it's thinking about things. But then it turns green and charges fine.

I didn't know about the waiting 30 seconds. I'll try it next time to see if that eliminates the brief red ring, but have never had an issue just plugging it in right away.

Ah so if you just leave it plugged after it turns red it goes back to green after a bit?

Mine does. Takes maybe ten seconds before it starts charging.

Until our garage rebuild is complete, we're using our Tesla Mobile Connector with the Lectron Tesla->J1772 adapter

It's working just fine at 40A (Since we only have a 50A circuit for the plug).

I'd expect the Tesla Wall Connector would work similarly fine.

I thought TMC only goes up to 32A. Maybe I misunderstood? In any event, how long does it take to go from 20% to 80% on your R1T when charging with TMC? TIA.

Depends on the model you have.

The Tesla Gen2 wall connector for example can charge up to 80A (useful for the Lightning, not the R1T) and all of them can be tuned down.

The Tesla Mobile Connector also had different generations. 1st gen could provide 48A. 2nd gen maxed at 32A.

I've been using my GenII Wall charger with the R1T since I got it without any issues.

The reason it goes red first is because Tesla uses its own communication protocol.

The wall charger or mobile connector looks for a Tesla signal first, before providing power. While it does this, the Rivian says - wait, I'm not getting any power. Something is wrong and indicates that with the red.

Once the charger realizes that it does not have a Tesla communication protocol, it goes into a non-Tesla mode and says - alright provide power anyway. That is when your truck will start receiving power and goes green.

Thanks for the explanation. I guess the Tesla Mobile Connectors currently available as new from Tesla are the 2nd gen.

That’s correct, but the Gen1 can be found as well. I think I’ve got 2 sets in my basement that has never been used.

Same experience. The Tesla charger with adapter resulted in slightly less charge rate than standalone charger for Rivian or non Tesla cars ( CCS).

There seems to be no drop using aCCS charger with Tesla adapter, to charge a Tesla.

You can’t really compare level 2 and DCFC rates.

I had a NEMA 14-50 outlet installed in my garage about a year ago “in the event that I ever went to an EV”. Well - that day is approaching rapidly. In looking at my NEMA 14-50 circuit a little more, the electrician put a 50 amp circuit in. Based on what I’ve been reading here, I presumed he used THHN and so I could swap to a 60 amp circuit and be fine for my hardwiring of the Rivian charger.

In reaching out to the electrician, he indicated that #6 is rated for 55 amp. Does that imply that he only ran NM-B wire?

Sounds like it. 6 gauge can handle 65-75 amp unless it's NM-B or UF-B.

Points deducted from your electrician for limiting you to 50 amp if you told him you were planning on using it for EV charging.

What? No. I get 24-25 mph charge rate with my Tesla Wall Connector and Lectron adapter.

(240V/48A on a 60A circuit)

My electrician did confirm Romex which would only be rated for 55 Amp. That sucks…. I would have surely hoped that he would have “future proofed” me a little bit to accommodate a higher draw in the event that I needed more than NEMA 14-50.

On the other hand, I should have researched it more myself a year ago. I just really didn’t anticipate that I’d be going to an EV relatively soon (1 year later) and so I didn’t research the difference between a NEMA 14-50 plug vs what a wall charging unit draws. I didn’t even know the right questions to ask back then.

I had the electricIan at my house because of an addition that we were putting on and the garage outlet was just something additional that I had him do at that time.

Code is that amp draw can't be more than 80% of your breaker rating. So 60A breaker gives 48A draw. 50A breaker gives 40A draw.

Been charging my R1T at 40A with my Gen2 Tesla charger with a Lectron adapter for last 4 months. Lately, I have had to reset the charger because it gave a red light fault code.

I've got a gen2 Tesla HPWC, hooked to a 100A circuit, so it's set for 80A output to the vehicles. The Rivian obviously can't take advantage of this, but I expect future vehicles might be able to...
I have noticed, as others have, that it'll go red when I plug in, then if I just leave it, the EVSE kicks on a couple seconds later, and all is green.

I've been doing that since I got it in late December, no issues. I'm using the Lectron 48A adapter (https://ev-lectron.com/collections/...obile-connectors-black?variant=39707339063342)

I have noticed that it's a little stiff to insert into the truck, that got a little better over time, but not much. It's ok, not unusable, but it doesn't just slide in.

Has anyone has a Tesla Gen 3 wall charger just not work, no matter how long you wait? I just received delivery of my R1S and get same behavior with it not working, but no amount of waiting with it plugged in resolves the issue. I'm about to pull the trigger on swapping the Tesla charger for a Rivian one, but then fear running into problems charging the Tesla (as I've seen in other posts). Next thing I will try before that though is ordering another adapter to see if maybe the adapter is at fault. What a pain.
