Thanks!
What is the best two-vehicle home charging solution for a Rivian and a Tesla?
My wife drives a 2021 Tesla Model 3 and I have a Rivian R1T on order. We're moving into a new home in a couple of months, and I want to set the garage up for effective level 2 charging on 60 amp circuits. As I understand it, my options are:
- Install a third-party two-cable charger, with a Tesla adapter on the appropriate cable for the Model 3, that will share the electric load between the two vehicles.
- Install two Tesla chargers, connected through WiFi for load sharing, with a J1772 adapter on the appropriate cable for the R1T.
- Install our single Tesla charger and manually switch the cable between the vehicles as needed, with a J1772 adapter when charging the R1T.

Good to know! Thanks.Tesla also has a J1772 wall connecter so you could do 2 tesla wall connectors, one with tesla connector and one with J1772.
Thanks for the helpful insight.We have charged two EVs (MS and Chevy Bolt) using a single Wallbox 40A charger (EVSE) on a NEMA 14-50 plug that can reach both car's parking spots for several years. I use the j1772 to Tesla plug adaptor for the Tesla. Even though it is on a 50A circuit, I currently have the Wallbox limited to 32 amps just to give an extra margin of safety. Even at 32 amps, we have never had a problem managing both cars. We drive each car around 1000 miles/month and often go several days without charging either car. I would go with whatever EVSE you like and use an adaptor for the other car, either Tesla to j1772 or j1772 to Tesla. Few people will need two EVSEs unless your daily mileage is really high. Although if time of use charges limit the times you want to charge then having two might save money over time (we have a flat rate, so doesn't matter when we charge).
Great ideas, thanks!I have a Gen 2 Tesla wall charger that charges my wife's Model Y. I charge the R1T with the same charger using a Lectron J1772 adapter. Both vehicles charge flawlessly. We have never had the need to charge the same night.
New home...do yourself a favor and add solar and possibly Powerwalls if you can. You'll basically charge for free and won't concern yourself with vampire drain on either vehicle.
Good insights. Thanks, Jim!I have a Model 3 and R1T charging in the same garage. I went with a Nema 14-50 on the door side of the garage for the tesla as it sticks in the back and can charge at 30 mph on a 40 amp circuit. The R1T has a Rivian charger on the opposite side of the garage for a nose connection at 22 mph and a 60 amp circuit. I can get by with just the nema, but have to back in the R1T and only gets 14 mph, very awkward and slow.
Same situation here with my wife’s 2021 Model 3 and just took delivery of my R1T 3 weeks ago. She drives more than me but so far we just use the NEMA 14-50 outlet in the garage with a 50 amp breaker and the portable charger from her Tesla. I bought an adapter for the R1T and just alternately charge whichever vehicle needs more juice at the time. There are several stores in our area that offer free charging while you shop so I use those for the truck quite a bit but we are never hurting for range or anything. Depends a lot on your needs but the one charger is more than fine for us. Grizzly-e makes a “Duo” charger than has two cables to simultaneously charge two EV’s at a time if you think you really need it.

Yeah, I'm starting as a Tesla driver too, so my initial inclination was to hardwire two chargers (of course, I already have one, so I'd have to purchase that J1772 model) and let them coordinate charging of two vehicles over wifi. The downside of this is I have to wire two circuits, instead of one, and I still have to purchase a charger.If your panel can handle it, I would recommend a two vehicle system that can share one 60 Amp breaker for 48 Amps of total charging. That gives you 48 Amps for one vehicle and 24 Amps each when you plug both in. That should cover most situations. I have had good experience with the Tesla products, but then again, I started as a Tesla user..,

Thanks for your input!
That was what I had in my head when I first decided to reserve my R1T, so maybe I'll stick with it. Using an adapter, rather than hardwiring the J1772 cable, gives me the flexibility of using that charger for the Model 3, should I need to shift my garage configuration.In terms of design, quality, and best bang for the buck you really can’t go wrong with the Tesla wall charger. I have the same situation where we have a Tesla model three and a Rivian R1 T. I was able to pick up a Tesla wall charger for 350 bucks and it outputs 11.5 kW. I purchased an adapter on Amazon that converts Tesla to J1773 and it works perfectly for both the Tesla and the Rivian, The Rivian is able to make full use of the Tesla charger power and sucks down the full 11.5 kW. It is I believe the simplest and cheapest solution and is an incredible value.
Thanks for chiming in!
How is this working out for you? Are you able to schedule overnight charging in both the Tesla and the Rivian? The Grizzl-E Duo is a "dumb" charger that supplies juice, at the appropriate shared setup, as soon as it's plugged in, so setting up scheduled charging on the vehicles themselves will be pretty important with this option.I am considering this for the exact same reason. To charge 2 EVs (Tesla and R1S) parked in the home garage.
Since both vehicle is not likely needing to be charged at the same time (rarely at the same time), thought it maybe easier to have one cable for each vehicle.

Works like a charm. I never really find myself wanting for more power that would come with 2 dedicated plugs. But you’ll have to evaluate what your needs will likely be. If this set up would work for you, then it’ll save you $$ vs buying and installing 2 separate EVSEs.
That's what I was looking for. Thanks. My Model 3 has the same functionality, so I'll be OK with the Grizzl-E Duo.I don’t regularly set charge times as my electricity price doesn’t change throughout the day and I have no other need to. In the rare cases I wanted to set charging for a specific time (like when going on a trip and charging to 100% right before I leave) I use the rivian’s scheduling feature to do it.
