Help - did my battery shrink? Weird range estimation changes

[Ventorum94]

Not on the calm screen, but you can put it on your center display while using the calm screen.

And to add to that, you can use one of the resettable Trips (Trip 1 or Trip 2) to show current or recent efficiency; rather than using it as a Trip cumulative, reset it often to show efficiency for the last 5miles, last hour, or since you turned into that headwind, or since the temperature fell, etc.

Took my first longish road trip (little over 300 miles) with my F150L yesterday / today - I have the ER battery pack...

BLUF: For some reason the computer thinks I will only get 210-230 miles out of the battery pack! This morning I started out with a range of 340 and before I drove 100 ft the total range reset itself to 232 miles! Is this just a computer hiccup somewhere (or a setting I can reset) - or do I have a bad battery pack???

Details: This may be an important detail: the days before my trip I was in the mountains nearby for a few days, making multiple elevation changes on dirt roads, not driving much more than 30 mph (except for the 30 highway miles back home) - my battery was pretty low before I started my road trip so I charged up at a DCFC before leaving town on my roadtrip yesterday morning. Just thinking about the 300 mile range, I thought I would have to recharge once but didnt pay much attention to the details.

I am not towing a trailer, have zero payload besides a small piece of luggage, the weather was clear to slightly rainy in the 50s-60s, and no significant winds. Average speeds were 65-70 mph for the trip.

Turns out I had to recharge twice because the computer kept barking at me that I was going to run out of juice!

On the way back home I took notes:

When I started Leg 1 of the trip, I started at 100% charge with a range estimate of 340 miles. Before I drove more than 100ft, the range estimate reset itself to 232 miles, after displaying the message "Range revised due to destination route". The computer said I would arrive at my charging station stop 166 miles away with 27% charge remaining (meaning I'm using 73% of the battery for a 166 mile trip - meaning a 227 mile full battery range)

I actually arrived at the charging station at 48% ( 166 divided by .52 yields a total battery range of 319 miles, this leg was easy highway driving, very energy efficient)

I charged up to 77% before leaving for home 133 miles away. The computer estimated that would get me 167 miles (again, acting like a 100% SOC would only get my 216 miles). I got home with a charge of 19%, which the computer told me was good for 39 miles ( 39 / 0.19 = 205 miles !) So THIS time the range estimate seemed accurate!!!

Does anyone have any idea what the HECK is going on here? Why would the range estimate start out at 340 miles and them IMMEDIATELY drop to 232 miles? (FWIW, the Ford Pass app on my iPhone pretty much mirrored this info).

This is kind of a deal breaker - I think I can live with a 300 mile range, but not a 220 mile range! I've heard that faster speeds will burn more juice, but THIS much more???

Any ideas here?

I had that happen on a trip, too. Try going into charging app on the truck screen, and “ reset your driving range “. Then it it will be right again. THEN drive without using Ford Navigation app, and let it learn how you are driving:; I find it is pretty accurate estimator for speeds around speed li it +/- 2 or 3 mph. The faster you go, the wilder the guesstimates.

After driving a 100 miles or so, can use Nav to get you to next charger with battery preconditioning. Occasionally have to reset again. But way nicer to drive 250 miles before charging!

And I get 2-2:4 mpkwh driving country highways, lor in town. All depends how close to 50 mph I drive. Which some days is not close!

It's been WAY too conservative lately. I went somewhere and used 60% to get there. I charged to 75% to go home, the weather was essentially identical. It kept telling me I wouldn't make it. The whole way it said I would have a deficit and it kept routing me to random car dealers. I just went for it. When I got there it kept saying I only had 14 miles left, and I kept driving to the next place and it continuously told me I needed to drive 10 miles to charge and then come back in order to go 4 miles away. I got home and it STILL said I had 14 miles left.

I wouldn’t avoid using the nav just because it screws up the GOM even more than normal. After all, it’s just the GOM…..the actual range is unchanged.
