Best EVSE Setup for Two EVs on One Circuit?

[Al_V]

I'm aware of this, so the setup would need some power sharing/limiting capability.

(2) 40 amp chargers could conceivably share a 100 amp circuit.
However, it is probably/maybe a code violation in one way or another.
I am far from an expert on NEC.

You can do this with 2 50 amp circuits coming off a 100 amp subpanel. Honestly, I'd probably do a 60 amp and a 40 amp circuit with a 48 amp and 32 amp EVSE respectively. The Lightning uses more power than most other EVs.

^^^ Exactly!

That is what I would do especially if I already had a 100 amp EVSE and the electrician had run a neutral to the existing 100 A EVSE.

Since I only have a single Tesla Wall Connector wired to a 60 circuit then Daisy chaining 2 Wall Connectors is the most logical solution for me. I have 2 Teslas and a Lightning. Right now I unplug one car when it's charged and plug the another in. It's a small pain in the A$$. Automatically being able to charge 2 at once should be slower that a 48a and 32a but I wouldn't have to remember to unplug and move it to the other car.

Fy friend has a new Universal Wall Connector that he hasn't installed in his house boing built. His partner doesn't want anything Tesla in the house and told hi to sell te Wall Connector. I may make him an offer to buy it at a discount since I would ot have a warranty as a second owner.

Im also curious about this, but I currently have a single 100 amp circuit for the lightning with CSP. If/when we get a second EV, it seems like it may be more cost effective to share this circuit than run a new one, although it isn’t far. I don’t really need the full 80amps either for the Lightning.

Two tesla wall connectors make sense with this setup too? Looks like you could set up each to charge at 48 amps? Or is the 100 amp circuit a problem?

As of last October, Tesla was still selling the 2nd-generation Tesla Wall Connector through their commercial sales and I believe they still do. The 2nd-gen is/ was their recommended unit for commercial destination chargers and you can share up to 5 of them on a single 100A circuit. The new 3rd-generation chargers can share a single 60A circuit or can be load-balanced on individual circuits so they don’t over-draw your service.

Grizzl-e was supposed to be coming out with a higher-powered version of their dual-charger that would install on a 100A circuit, but that hasn’t materialized just yet. I know their current dual-charger has been a little problematic for some people.

But if the wire run from the panel is short, you’re probably best off just running a separate circuit for a second charger.
