Severe GOM discrepancy

[LeanneL]

So 1 more question. Did a full factory and EV stat reset. I know GOM is not accurate but it’s so far out of line that it is bizarre. Currently at 49% charge and shows 109km range for an extended. Not terribly worried as my stats in Car Scanner look ok, but anyone ever seen this? With my Mach E it was always the opposite with the GOM being wildly over the top.

Figured it out! For some reason, it was stuck thinking it had a trailer attached

That was going to be my suggestion for you and future viewers of this thread, the pesky trailer attached is usually the culprit

if you tow a trailer, and disconnect the trailer with the truck off, you have to manually tell the truck you don't have a trailer attached.

Take energy / SOC (displayed) * efficiency. That's your current range.

The trick is to leave the truck ON when disconnecting a trailer.

Yes that estimated range is out of whack, should be a lot more double by my guesstimate.

I think it should be the full (100%) HVB Energy x SOC x efficiency in km / kWh.
(That way the kWh cancel out and the range result is in km.)

If you use Car Scanner, you know the remaining energy "E", then E (in kWh) x efficiency (in km/kWh) = Range (in km) assuming that efficiency holds up for the trip.

The Car Scanner numbers are a bit funky: if the SOH is really 100% and the 47.1% is really 61kWh, then the HVB had a total capacity at 100% of 129.5kWh but the usable should be 131kWh and with the buffers 143.4kWh so something is amiss. Also the dash display rounds 47.1% to 48%? WT Fudge.

It's all a guess-timate anyway...

But if you don't have Car Scanner numbers, just go with 131kWh x SOC for the energy, the multiply by the km / kWh efficiency. So 131kWh x 48% = 62.88kWh; and let's say an efficiency of 3.5km/kWh (which seems to be the average owners report) then round things of to make life easier:

63 x 3.5 = 220.5 km range (or 137 miles)

That whacky guesstimate of 109km is an efficiency of about 1.7km/kWh (1.1 mile/kWh), not great...unless you have a heavy load to pull up a hill?

Yes the EPA estimate is about 2.44 miles/kWh for the ER equipped Lariat, but I think 2.2 is closer to reality.
