Max charge rate for a level 2 charge for the MachE

[Triggerhappy007]

For you electrical guys, it’s 46amp because I’m plugged into 208V power, not 240. Here is my charging curve from this morning.

I'm also at 46A and I'm on 240V. I think it has to do with the car, not the voltage. I think 46A since that's 11 kW at 240V.

Sort of. My Autel is set at 50amp, but only puts 9.5 kw to the car because I’m operating at 46 amps x 208v = 9,568W. I can’t remember why I figured the 50amp would only put out 46amp. I’ll ask my maintenance manager.

Mine shows 11.1 coming out of the autel and fordpass shows 10.

Which indicates your 240V outlet is 60 amp (11.1 kW figure) and Ford Pass showing 10 (kW) is the internal battery rate

The mobile charger that comes with the Mach E started out as a 32A charger but may now be 30A.

Or a door stop

Measured at the outlet is what is posted. Measured internally is more like 8.x

Which is still more than 32 amps.

I just got my Ford Charger installed today and hoped to have faster charging, but it showing a charge rate of 3.1kW... that doesn't seem right.

Which Ford charger? What do the indicator lights show?

 

[hammerg26]

Ford Charge Station Pro.
Flashing Blue with Amber on the right - per the instructions, it is "Charging at a reduced rate"

Not sure what to do next. :|

Update: Called Ford. They had me reboot the system (turn off breaker for 7 minutes, let it reboot for 7 minutes).
In the meantime, I validated that it was set internally to 5 (which matches 48 amps on my 60 amp breaker - yes, a licensed electrician installed it).
I also updated the Ford Pass app to set the max charge to 48 amps (it was at 6 amps)... no idea what fixed it, but it is going at 10.1 kW now... and the light is "pulsing blue" ...

final fun fact... called Ford enough times today that I got the same dude 2x... what are those odd?!?!?

The limit was cause by the setting in the app. Glad you got it resolved.

My hardwired Emporia is set in the app to 40a

Took 7+ hours to go from 8% to 100% yesterday.
I wasn't using it after 5pm, so the rate vs time equation was moot.

This is why I haven't bothered to switch it to 48a.

So I save an hour or two, at the expense of everything working harder.
Not worth it.

Yes. During the summer I don’t bother above 32amps because my garage that is ‘normally’ 100 degrees can get up to 120 because of the fans when charging at 48 in my sealed garage. It also sounds like a landscaping crew having blower fights in the garage at 2am. I’m also almost never in a hurry to ram electrons in so I can sleep on it. It’s diminishing returns above 36amps. I have a brand new wall connector under my work bench because it would throttle it’s self when the garage hit 110.

Up here we never get 100 degrees and my fans never came on. Not when it was charging as purchased and definitely not now that software was installed such that it will not go over 30 amps. I do not agree with the demising returns as 90% charge can now not be achieved by the next morning if you are a long commuter and going from 80 to 100% before a trip is just brutal at 4 5 KW. It is a definite depreciation of the car that it will not charge to spec. It is an EV and charging speeds matters. It is always nice that you can slow it down but top end in anything matters and this car has been crippled by software. What does ford say about that nothing.

Not sure how you made out with this (and I don’t feel like reading the whole thread), but I installed 2 Autel units at my work and I charge at 46amps everyday. For you electrical guys, it’s 46amp because I’m plugged into 208V power, not 240. Here is my charging curve from this morning.

I know your post is old but I just saw it. 208V doesn’t affect the current drawn, it affects the amount of power your car is pulling overall. 46A x 240V = 11,040w or 11kW. 46A x 208V = 9,568w or 9.6kW.

FWIW the Mach-E for whatever reason only pulls 46A instead of the more common 48A max that most EVs can pull when AC charging. I’ve confirmed this in-car via CarScanner and via my Chargepoint Home Flex which clearly shows that my Polestar 2 pulls more power than my wife’s Mach-E. I dunno why Ford chose not to give us those last two amps but they did.
