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.

Am I missing any other options? Who is using one of these methods? Pros and Cons? Any insight is appreciated.

If you have capacity in your load center, I'd run 2x 60A breakers and have two dedicated EVSEs.

If you don't have capacity, then you could go with EVSEs that power-share... Tesla is one option. Wallbox is another.

Tesla also has a J1772 wall connecter so you could do 2 tesla wall connectors, one with tesla connector and one with J1772.

Good to know! Thanks.

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).

Tesla MY: My wife uses portable charging cable to a NEMA 14-50
R1T: I have Rivian charger @ 50amps.
I agree with others. If you have the capacity, then two separate 60a w EVSE.

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.

We have this EVSE, and it has worked well for us charging 2 J1772 cars (R1T and ID.4). Like you we rarely have to charge at the same time, but it is nice to be able to plug them both in and have the EVSE manage the charging. You get full 40A when only one car is plugged in, each get 20A when both charging, and when one finishes it keeps 8A, and the vehicle that is still charging gets 32A. Have had it about a year. Very robust, and simple. I prefer to let the EV do all the "smart" features with scheduling, etc. (though we don't actually use that as we don't have time of use billing. This was the cheapest solution I could find to be able to charge both simultaneously (if needed) and not need an extra circuit.

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.

Great ideas, thanks!

The Grizzl-E Duo has the ability to power share and it is all in one unit. Don't have one but have been researching this myself.

I also have the Grizzl-E duo. 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.

Sorry if this was mentioned but with grizzl-e on their website you can configure a duo with mixed plugs

I think that might just be for the holder. Not sure why they would give you the Tesla option, it specifically says it has "two 24ft J1772 charging cables".

Also just noticed the price is now $100 less than I paid, making it an even better deal!

I have a Tesla Model 3 and I will be getting a Rivian R1S this Summer. Personally, I'm going wit the 3rd option.

" Install our single Tesla charger and manually switch the cable between the vehicles as needed, with a J1772 adapter when charging the R1T."

My rationale is minimize cost. I also don't need to charge the two vehicles simultaneously.

Lectron V-Box and tesla adapter. Hard to beat the price and performance. quality build

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.
