The manual is ambiguous on this for LFP batteries. In one paragraph it states to charge to 100% once per month. In another paragraph it states: "During regular use, you can increase the battery life by maintaining the state of charge at 100%."
The range is based on the state of charge (or energy to empty). So if the range went down, it means the state of charge likely down as well (unless there are dramatic temperature swings at play). The problem is Ford uses some hysteresis on the state of charge display. Basically the % won’t go down while you’re parked, it will start rapidly adjusting down when you start driving. That’s why you might initially see the range go down but not the % change when you start the car. There’s a lag between the displayed SoC and the actual SoC.
I’m not sure I understand your statement. The battery actually loses that much stored energy? This may be a silly question, but where do all those electrons disappear to so quickly?
This should literally be a sticker inside the charge door. Just saying.
No, it gets confused as it uses an avg driven kw range to kw energy in the pack to make it's calculations. It's the'smart' thing that says how much you have divided by how you drive (kw/m) +/- temp conditions = how much range you have.
The battery is not actually losing any energy, the computer’s estimate of how much energy in the pack is changing. Think of it like a bad gas gauge. The tank might be almost empty even if the gage says it’s half full. Filling the tank full resets the gas gauge computer so it has a better estimate.
I think I I’ve got it. The battery never had the capacity the GOM stated. It just took some time to adjust the reading. I have never noticed this in our MME with a lithium battery so this is a quirk with LPF batteries only? Thanks for the explanation. I bought the car to learn about the new technology and I continue to do so after 3 years!
Did it work?Thanks for the advice. I rarely charge to 100% but I’ll be more diligent going forward. I’ve had the car almost 2 years now and this never happened before so I was super worried
The NMC battery should be occasionally discharged below 15% and charged to 100% in order to correct BMS drift as well. Somewhere between 2 and 5 times a year should be just fine.
Wait, wut? If I do it 6 times, does it blow up?The NMC battery should be occasionally discharged below 15% and charged to 100% in order to correct BMS drift as well. Somewhere between 2 and 5 times a year should be just fine.

Very interesting. Can you please share where you got that info?The NMC battery should be occasionally discharged below 15% and charged to 100% in order to correct BMS drift as well. Somewhere between 2 and 5 times a year should be just fine.

I saw that. Didn't impress me. I'll just follow the manual.See @Mach-Lee ’s first post at https://www.macheforum.com/site/threads/hv-battery-calibration-procedure.23815/
There are other sources on the web but this one is on this forum.
