mobile charger with garage outlet

[syrc]

i'm sure this has been previously discussed but need a quick answer.

while i wait for sun run, i can't just plug in the 30A mobile charger into a standard outlet in garage, right? because standard outlets are 15A or 20A?

sorry, i did a quick search already.

You can plug it into a standard outlet. It will draw about 12 amps. You won't be using the changeable plug that uses the NEMA 14-50 socket. You won't gain range very fast, but it will charge.

I’m getting about 10% in 14 hours.

that sounds terrible when you put it like that but then again that should maintain many folks for most days.

It’s adding enough to get to and from work each day and when we got too low we made a quick trip to the nearest 150KW charger to top off. Totally manageable considering we’ve put 500 miles on it in 3 days…

Yes, yes it is terrible…my truck is on 120V/20A now…limping along until I get my FCSP delivered/installed/derated (until Siemens solves their issues). I’m averaging adding about 1.0 kWhr per hour of charge time……

I don't have the FCSP yet, but I had an electrician come out and run the #3 copper wire to where I want the FCSP installed.

As long as he was here anyway, I had him put in a 240v 50amp 14-50 so I can use that until I get the FCSP and have it connected.

You can plug it in. It’ll take you over a week to charge from empty to full. Only viable if you drive once a week.

If you have an electric drier that’s close to where you can get the truck, the dryer plug can be used and will do much better.

Correct. 1 kWh per hour on 120v.

No, do not do this. The Ford Mobile Charger pulls 30 amps. That requires the wiring and breaker for a 40amp circuit. 30amp dryer wiring is not adequate.

Is the F150L not amperage selectable like the Tesla?

Correct. It is not. Neither is the Mach-E.

Well that’s silly….but good to know. Thanks.

Some numbers, maybe F150 will be added.

That is what the 30amp breaker is for right? Its been a minute but doesnt the gauge wire for a 30 amp circuit the NEC calls for provide enough for 32 or 33amps? In either case I would be surprised if the F150 Lightning doesnt do a sense probe with a draw ramp.

Once my truck gets here ill do a test for this, I can monitor temp, volts, amps and some other parameters for my house wiring.

No.

The NEC says that your circuit must be sized for 125% of the charging current because it is classified as a continuous load (it does not cycle on and off like many other loads do). This means that for a 30A EV charging load, you require a minimum circuit ampacity of 37.5A - so you round up to 40A. You are not permitted to draw 30A EV charging load from a conductor rated for 30A.

The F-150 (nor any other EV, really) does not do a sense probe. It draws what the EVSE tells it is available, and it's not adjustable in the truck. And the Ford mobile charger with a NEMA 14-50 plug advertises 30A charging load to the truck.

Tesla (and other EV's) do have sense for potential high resistance problems (significant voltage drop indicative of an undersized circuit or an extension code) and will cut their current draw based on that. I'm not sure how much Ford looks for this or not.

Instructions with the Ford Mobile Charger indicate that the temperature, both internally and at the supply plug, is monitored and the output throttled if an over temp condition is detected. This causes the dreaded amber light, reduced output reported by quite a few people. I don’t find anything to indicate that voltage drop is monitored, but I found it interesting that the 14-50P temperature is.
