Bizarre Charging Max Varies By Charger?

[Triaspis]

No, this is not another "Why am I not getting the advertised 320 miles while pulling a trailer uphill in the snow with a strong headwind" lol

I have a "somewhat" fast charger available to me at work .... I say "somewhat" because the fastest it charges is around 23kw (verses my Ford charger Pro at home which is configured to pull the full 80amp its capable of thereby putting out roughly 17-18kw)

Anyways, when charging at home, I'm greeted with a 100% charge each morning showing somewhere between 300 - 320 miles of range on the GOM. (Yes, I'm aware of the potential degradation issues charging to 100% daily and I'm willing to take any potential risks posed)

However, when I charge at work to "100%" ..... The GOM routinely shows MUCH less range. ..... Oftentimes between 210 -235 miles

What i don't understand is how its possible for the charger you use to have such a major impact upon the GOM mileage estimates.
Why would the charger one uses influence such things in a not so minor way?

Anyone have any ideas?

Some background:
2023 Ford F150 Lightning (higher trim level) XLT ER
I've also played around in my settings making sure no limitations have been imposed on max charge and even set the "one time charge to 100%" option with no impact whatsoever upon my results

No answer for you, I'm just excited to actually see an interesting "Why doesn't my truck show 320 miles of range" thread.

Nothing to do with the charger. If your truck is in your garage that’s why you see the difference. It’s warmer in your garage than outside right now. For 97% of us daily commuting pay no attention to the GOM.

I dont know man .... I agree .... to a certain extent biers ..... But both chargers are outdoors/, in fact my truck has never seen a garage.
I realize the GOM isn't perfect, but 100 mile difference at 100% charge? 5-10% variance..... sure ok ...... But 33%?? ..... That's just bizarre

I charge my truck at a handful of places/chargers ...... But my work charger is the only one where this seems to reliably happen .... and for perspective ..... Ive had the truck since Dec 2023, currently have 37k miles on it and have charged in many places both public and private ...... Ive just never seen such odd behaviors happening on only one charger like this.

I've also searched the threads and have seen no mention of this in any of them, so thats primarily why I posted about it.
At this point I'm going to have to assume it's an issue with the charger and/or compatability communicating with my truck ..... but thats only an uneducated guess

I do however, very much appreciate everyone/anyones comments/input on this issue, so thank you

Is the work charger 110v maybe? Battery heating on the charger at home but not at the work charger?

I'm guessing the mi/kwh between the drive to work, and the drive home, is similar? You don't work at the top of a mountain do you?

 

[Triaspis]

Honestly I'm not sure about the work chargers Firn ...... I work at a University and these chargers were actually meant/installed to charger to charge a small fleet of electric busses for use on campus ...... They haven't even purchased the electric busses yet LOL ..... But it works for me!

I'm old, so yes, I travel 50 miles each way ..... both ways uphill, barefoot and in the snow! Lol

Actually, it's pretty much all flat NJ turnpike driving ..... 100 miles round trip each workday.

When I run into the head electrician here, I'll have to quiz him and see what he thinks about this anomaly concerning the charger

Im really leaning towards it being a charger or charger/car communication issue ...... Mainly because this afternoon I found that only 3 of the 6 chargers at work will actually charge me truck without causing the charger to throw an error and stop charging the truck ...... Yet no one else to my knowledge has experienced this error situation on the 3 chargers giving me issues ...... everyone else seems to have no issues with any of the 6 chargers ..... so who know what the he

 

[Triaspis]

Sorry about the flagrant typos and other grammer issues with my last post ..... that was pretty bad even for me! ....... I was trying to multitasking and we can see how well that usually turns out! Lol

I have no explanation for site variation, in that you can get a better GOM projection at home topped up at home than you can at the end of the day at work.

I would think the derated value should be consistent at either location.

At the moment, my Lariat-ER is at SOC 72% cold at 27° sitting in the breezy air of the driveway, it's projecting a range of 172 miles, factor that back to 100% the value would be 239 miles {172 / .72} this only slightly better than your experience, the outside temperatures this time of year have a substantial impact on projected range.

25% or more cut is not unusual.

Do you use departure timer while plugged in the morning prior to commute to work?

Do you use an afternoon departure timer also while plugged in at work for the trip home, this can substantially improve the GOM projection on the return trip?

PS: the past couple days my departure timer (while unplugged) has failed to start the truck for cabin warming.

You can reset the driving history.

fastest it charges is around 23kw (verses my Ford charger Pro at home which is configured to pull the full 80amp its capable of thereby putting out roughly 17-18kw

Is it a DC charger?

 

[TaxmanHog]

Is it a DC charger?

Good point of inquiry, the ER trucks onboard AC/DC 80 amp limit is an ideal 19.2 kWh, anything above this value is likely a DC charger.

Your home is at the top of the mountain and your work is at the bottom?

“Guess O Meter”! If you really want an efficiency number, use the actual trip miles and the actual kwh added.

I wonder if the truck is capable of a 96amp rate (2x48a)? That would give it 23kw ish of power.

More likely it’s the difference of regular and premium electrons!

No, in the ER trucks {my22 & my23} the two inverters are NOT equal in capacity, 48/32 IIRC

my24 ER trucks ditched the smaller inverter.
