Using Tesla wall charger with the Rivian?

[kizamybute']

Gotcha. That's important info to know regarding why you have a better charge rate now. I'm on a 50A circuit, meaning my charger won't go any faster and it's unlikely I'd get a better charge rate by installing the Rivian charger.

Likely your panel is capable of more than a 50 amp breaker. I think all houses are. 200 is common in older homes. Thus, you could just swap out the breaker and put a 60 amp breaker in place of the 50 amp. Assuming your wiring to the charger is capable of handling the extra amperage.

The electricians wired it specifically for 50A. If I wanted 100A circuit, they'd have to rerun a whole new set of thicker gauge wires to accommodate that. That's not worth the cost.

If you remember who did it, can ask them what gauge they used. 4 awg is recommended, but that's the same as what i have for the 100 amp breaker, so a little overkill for the 60 amp. 6 awg is acceptable for a 60 amp breaker, which, if they errored on the side of caution, they might have used to wire a 50 amp breaker.

I'm fairly certain they used 6awg for the wiring and used a 50A breaker in there, then set the Tesla charger to 48A. I'm fine with it, really. But It just means if I swapped over to the Rivian charger, I'd be unlikely to see any increase in speed. I could potentially bump the breaker to 60A, but whatever

Not a huge difference. With the Tesla charger, the Lectron adapter reduced it down to 48 amps and I got 20 MPH. With the Rivian charger, getting 24-25 MPH charge rate. So that's what the extra 12 amps gets you. I was good with the Tesla charger and would have left it if not for the remodel. Made sense then to just install the Rivian Charger.

I basically have the same setup. Electricians ran 6 awg for the Tesla Wall connector we had installed in the spring for my wife's MY. Used a 50A breaker but it can take 60A if we need it. Just got the R1T on Tuesday and have been sharing the wall connector using a Lectron adapter. So far no issues.

I have the Rivian charger sitting in a box for now. I may return it and get another Tesla charger and try to load share between the two since I can't get more than the 60A service in the garage. My Rivian delivery guy suggested installing the Rivian charger and then using charging schedules that don't overlap so that both vehicles can pull full 48A from their respective chargers (ie, Tesla from 10p-2a, R1T from 2a-6a). There's obviously a little risk with that if something goes wrong but it's an option. But for now we're just taking turns charging.

If you’re running an EVSE configured for 48A on a 50A breaker then that is bad. On a 50A breaker you need to limit the EVSE to 40A or less

What circuit do you have for the charger? 50A? I'm getting 9-10kW with the adapter, which is exactly what I was getting in my Tesla, too.

I have a 60amp breaker and the Tesla is getting 48A. I'm hoping for the same.

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 seem to recall reading that you need to wait 30 seconds after attaching the adapter to the Tesla HPWC before plugging into the car. Is that what you're doing?

 

[derekmw]

Oh no, I’m not doing that. My adaptor stays on the tesla wand and I just directly plug it in after I park. So that’s the trick I need to try?

Thank you to all the posters on this thread. This is such a critical part of owning an EV, I will certainly be checking this at the time we install a Wall Charger.
I had NO idea about all the requirements regarding amperage and wire gauge.

Ok, just read the instructions and you're right. This seems like quite the pain. I know, seems silly but I don't want to stand there and wait 30 sec each time I have to plug in. This is enough for me to maybe just ditch the Tesla Wall Connector and switch over to the Rivian one.

You may want to check TeslaTap to see if they have the same drawback. (TeslaTap makes several models that are compatible with the HPWC)

I have two load sharing Tesla wall connector. One has the adapter on it for the Rivian and it has not been a problem at all. Never a failed charge or connection.
