Ready For The Ford 80A Charge Station Pro

[hturnerfamily]

in the RVing industry, there are manufacturers installing electrical 'shedding' devices - which control whether a particular device(circuit) can be powered if amperage usage becomes too high within the main panel. An example is shutting down the power to the breaker(circuit) for the rear a/c unit, or the breaker(circuit) for the electric fireplace heater, etc. This happens on a 'circuit' basis, not just for a individual device or appliance. It's typically for 50amp 240v RVs when using a much more limiting 30amp 120v campground outlet.

I'm not aware of anything, though, to 'dial down' any specific device, as that would be at the device level, not from the the panel. Your 'device', in this case the EVSE charging device, would have to be able to 'read' the amperage level running thru the home's main breakers at the panel. That would be a much more complicated process, with return wiring back and forth between the two, etc.

The other option would be to use a 'shedding' device to shut down certain circuits within the HOME if the charging pushes the main panel's breaker total too high, such as the 240v 30amp water heater, or similar 'high draw' appliance, that operates behind-the-scenes.

Is there such a thing as a EV charger that monitors amps at the mains and dials down the charger if total house usage approaches say 200 amps but lets charger rip at 80 amps if other house usage is low?

No - the closest thing are EVSEs that communicate with each other that will dial back when charging multiple cars.
What you suggest could theoretically be possible, but would require smart home equipment beyond just the EVSE.

Could really be useful for a home with solar to maximize charging when solar output is high. For homes without solar, and the use case is night time charging, maxing out the mains would not likely be an issue.

I had an electrician propose a load shedding device for us, it would have totally cut out the EV charger when 85% of capacity was reached, and then restore charging 15 minutes after it was back down. They wanted an additional $700 or so, and the electrical inspector said it was totally unnecessary, so I said no.

I have 2 Generac load shedders (one each for 100g water heater and cooling/heating) and each was about $225.

Theoretically you could put one on a dedicated charger circuit (at the panel). They shut down the circuit and go to a timer based on upstream load.

Can the Ford pro charger also charge non Ford EVs- specifically Teslas? If I were to get a Tesla later after installing the charger pro, can I just use a regular adapter or will the DC plugs that are used for the backup system somehow cause issues?

Possibly. There is an issue that the pro charger has the same form factor as a CCS1 charger. So, you have those two extra lower lugs that are used to power the house - and not for DCFC, whereas CCS1 is normally used for DCFC.

As long as you had a Tesla to J1772 adapter that had an additional notch to work around the small extra bit of plastic that goes to the CCS1 component, yes it would work.

Out of the box, it is physically incompatible because of that extra bit of plastic. Though, nothing is stopping you from filing that bit of plastic off - or maybe Ford will remove it in production.

I highlighted the bit of the CCS1 component that does not match up with the J1772 adapter:

You might be able to get by with a CCS1 to Tesla adapter but.... Remember those two lower ports are not powered. So I am not sure it would actually work.

Isn't there a tesla adapter that just fits the top, or is that what you are saying will conflict with the plastic piece?

If you look closely at the collar of the J1772 side of the adapter in this screenshot, you will see it can't plug into the Ford CCS1 style plug because of the little lip. You could dremel this off, then it would probably work fine. But without doing that, it will prevent mating.

thanks for the info. I guess I'll deal with that problem down the road if I add a second ev. With enough Ford chargers out there in a few years someone might make a ford to tesla adapter that fits.

Maybe the Tesla CCS adapter will be available in the US soon. That would allow you to plug it into the Ford connector without any modifications.

It has been claimed by many power companies that they can disable an EVSE by over the wire commands. They'd do that to protect the grid. Not sure how they can do it, I've sent emails to one power company asking how and they didn't reply. I'd think that they can control power to the dedicated smart meter but doubtful that they can reduce the power.

Someone would have to show me the NEC for a software device that can control power in a home. They usually don't trust software. If a dedicated electronic component was used maybe. It would have to fail in either lowest power or fail totally to be trusted.

Taxman,
Is this the hardware that Sunrun is going to sell us for intelligent back up? If so, where did you get it? Thanks!

Just a note. The Pro charger won't benefit a Tesla. It can't use more than a standard L2 charger. It's super charger is ac so the CCS can't be use.

Get the L2 J1772 to Tesla adapter if needed. Then consider the Tesla to L2 J1772 in case. I keep that in car.
