2 Different Chargers

[brewski]

We have a Tesla destination charger that I currently use, but it is a PITA since it is in the wrong place, among other things.
I received a Ford charger with my truck.
With the 60amp for the Tesla, I'd have to dial mine down to 60amp to avoid upgrading the panel.
Still, with both operating at the same time IF the AC kicked on or IF we ran the dryer and oven at the same time, we could trip the main breaker.

An option offered up was to have a switch that would only allow one of the chargers to operate at a time.

I really don't know what makes sense, and I'm open to suggestions.

If you currently have a Tesla wall connector I would just buy another. Or the J1772 Wall Connector. They can share power with up to 6 wall connectors

I'm not against this (they are currently out of stock).
Yet, IF I want to use the Ford charger...

If you need to charge 2 at once then a load sharing system would be ideal.

Check out the grizzl-e duo or one of the many other brands out there that you can link and loadshare.

I don't ever plan on having 2 at a time charging, we'll just alternate days when we go to 2 ev's. I'm currently only charging at home every 2 to 3 days.

IF I ever need a 2nd evse then I'll run a seperate outlet for when ever the need arises or as a backup if the fcsp ever fails.

I would get the J1772 version of the tesla wall charger and set them up for load sharing

At least Amazon has it in stock (apologies if you're not allowed to post links, but it's a bit of a challenge to find it).

IF you want to use the Ford charger you can install a load balancer between the two, but the cost would probably be as much as just getting the Tesla charger - so why not get it and sell the Ford charger.

How many miles a day do you put on your vehicles? How much time do you have to charge them?

You could derate both EVSE to 24A charging and still get over 90kW to the batteries in eight hours.

Other than that, the suggestions to get the J1772 Tesla and load share are excellent.

Assuming you will not change chargers, you have the following options:

1) Derate one or both of them to a level that when both are running AND the AC is on (or dryer, or oven), the main breaker doesn't trip.

2) Install that switch.

3) Install a load shedding device as suggested, which will cost more than the Telsa charger as stated.

4) As stated, use chargers that have built-in load sharing. Tesla does, other brands including JuiceBox do. I am installing shortly a 2nd JB charger, for that very reason.

There are no other options.

Ok...ok...you guys win.
I just bought a Tesla J1772 charger (was out of stock on Tesla site, not at the big A).
48 amps is plenty for my normal charging needs.
Load sharing simplifies multiple things.
Guess what??
I now have a new-in-box Ford Charge Station Pro for sale.
Reach out if interested.

I quick update: When talking Tesla Wall Connector...version matters.
Ours is a Gen 2.
It can load share certainly with another Gen 2.
CAN'T load share between gen 2 & gen 3.

Worth mentioning for anyone stumbling across this thread later looking for a similar solution:

NeoCharge makes an automatic switchbox that lets you have 2 EVSE's connected to a single receptacle. It doesn't load balance, but it will autoswitch between a primary and secondary. I've been running one at my home for over a year to juggle charging 3-4 EVs, and it was a good cheap solution for my needs.

I now have 2 Tesla Gen 3 chargers installed (a Tesla & a J1772).
You can NOT load share between a Gen 2 & a Gen 3.
Gen 2 load share is hard wired, while Gen 3 is all software.
The interface to the charges is marginal at best.
It is all an html interface, no app.
Neither commissioned as they are supposed to.
Support was weak, but I prevailed.

I tested my truck. Previously I've been using an adapter to charge with our Gen 2 Tesla charger.
It would NEVER follow my schedule.
When I plugged in there were all the right sounds, then...nothing.
I looked at the Ford app and it said "waiting to charge at 11pm".
Yay!

General steps:
1) Provision each charger independently, which includes putting them on your wifi.
2) Once both are provisioned, log into one of them (no, not on your wifi, on the device wifi) and then select load sharing.
You'll have to input the other chargers wifi credentials.
At the top of the screen there are, what appears to be, 2 selections:
Disable & Enable.
Enable is "lighter" and it appeared to be enabled.
We found out that night it wasn't as neither charger did their thing.
So I fired up the charger wifi and looked for error messages.
Nothing.
I decided to tap Enable.
Bing!
Now Enable is actually "lit up".
I just tested and it all works as advertised.
Doing this prevented us from having to go beyond a 200amp service at our house.
