Ford Pro Charge Rates… Really.

[Pioneer74]

Yeah, taking the credit. Looks like that little Emporia 48A Charger is a good unit for under $400.

If you're not in the market for it immediately, look for a sale from them around Black Friday. They did it last year for sure, and possibly the year before that.

How many miles do you drive each per day? Do you return to the house sucking electron fumes, or more like 25% remaining? Is it every day? Both trucks? How many hours do you actually have for charging?

40 amps will charge the ER from 0 to 100% in about 16 hours.
48 amps will be like 13 hours.

Yep, I bought one on Amazon for $299 on Nov 11, 2023. One day only.

I’m kind of amazed at how many chargers have popped up since I traded off my 2022 lightning. It’s been under a year, but it’s staggering. Then, add all the Tesla chargers that are available, which I usually see vacant, and it seems to really Take hold of the rain, anxiety and throw it out the window. I can charge daily at home, and at work, unless my son gets a lightning at the same time and then we need to figure out how to share or piggyback two chargers. Not to convince the darling wife that I’m not stupid.

Take the 2k from ford. Get 2 ev chargers or use the evse’s that come with the lightnings and one of these auto switchers. Then you both can plug in and when the first truck is charged it will auto switch to the other one.

At the house i have a ford 48 amp (powered by a 60 amp circuit that I bought off the website that was delivered in two days while I waited for the 80 amp included with my truck that took 2 months after the dealer had to call the regional rep.) that is getting around 25 mPH

at my shop I have an 80 amp that came with the truck that is getting anywhere from 30-35 mph.
So 30 seems reasonable.

So I’m more confused. Probably due to ignorance. Accept my apologies.
Order guide says the peak level 2 charging rate on a 2024 Flash is 11.3kW. I’m assuming in a perfect world, that is effectively saying a Lever 2 EVSE sucking a full 50 amps on a 220V circuit could deliver 11,000 watts, or 11kW, and THAT is what the Flash’s charger COULD use… MAX.

So, could I put one 60A breaker and one 40A breaker in a 100A panel. Set one charger to 48Amax and the other 32A, and charge simultaneously. If both trucks chargers are in top shape, one will receive 10.5kW per hour and the other about 7kW per hour.

Will an EVSE pull a full 48A if set at 48A? Or are they derated, too. I wish I could put two sixty amp breakers in the 100A service, but I guess it’s a no-no. I guess I’d have to mic the cables and see what is actually drawn at full load?

 

[TaxmanHog]

~240 volt x ~48 amp = 11,520 watt hours aka 11.52 kWh

Reality is your mean voltage could be anywhere from 220 to 240
And the EVSE might actually only draw 46-48 amps.

My FCSP designed for 80 amps x 240 volts for a stated theoretical 19.2 kWH, it generally draws ~77 amps and according the my emporia logger, produces about 18 kWh at appx ~235 volts.

Yes.

Yes. As long as the vehicle can accept it. Which the Flash can.

If you have a 100 amp panel in your garage, and there is nothing else being fed from it, you can draw a total of 80 continuous amps from it. Divide it up how you want.

You’ve got the basics.

Either 2-50A circuits with 40A EVSEs, or a 48A EVSE on a 60 plus a 32A EVSE on a 40.

There have been discussions among NEC panels members about the feeder derating only applying to the largest EVSE when there are more than one, but any change (if it happens) won’t happen before the 2029 code. If the change is made, it would allow a 48A and a 40A EVSE on a 100A feeder or service.

I REALLY appreciate you all helping me! THANKS!

One question…. If my son and I are both preconditioning before work, will the one on a 40A circuit with a 32A EVSE still precondition WITHOUT taking juice from the battery? I’ve read it has to be on a 40A minimum.

It will work well.

 

[Firn]

Any reason to not go with a single charger with load balancing? That way both can charge equally, but if one finishes the other automatically gets more juice to finish it's charge sooner.

 

[Smokewagun]

Well, the only reason is my son may have days that he would need to replenish close to 65% battery in 8 hours. I’m just considering winter, assuming drop to 1.5 miles per kW and needing to replenish 130ish miles of range by the next morning. Isolated case, but maybe a reality with no ICE vehicle fallback. He’d have to get more charge overnight. In fact, he may every night.

Prepare for mid trip charging outbound or homebound as a supplement for the worst of winter trips.

An earlier post mentioned the Tesla home chargers with a load sharing option. Emporia makes one also:

https://a.co/d/7OFHl8f

I hardwired a 48 amp Emporia and it charged my Lightning ER from 13%-90% / 104kWh in 9hr 41min last weekend. The Emporia app shows that it pulled 11.6 kW the entire time.

After reading through your questions and all of the suggestions in this thread, if I was in your situation, I think the 48amp load sharing option of two separate EVSE's makes the most sense for your barn and multiple Lightnings. 48 amp EVSE's are a good compromise of power used and speed of charge. The load sharing sounds like a great option to keep your electrical service safe.

One other point of complication that I just thought of... If your barn is a "sub panel", dose the main panel feeding it have the capacity for potentially 80 amp continuous draw to that sub? My barn electrical service was wired by an electrician and inspected by the state. My main panel feeds my barn via a 60 amp breaker, but the main breaker in the sub-panel in the barn is a 100 amp breaker. The electrician told me that it is still a 60 amp service. I don't really understand the voodoo of it all, but apparently it's legit. Might be something to check before you spend the money and time in the EVSE install.

My Emporia is on my house 200 amp panel, not in my barn.
