100% charged by Airport valet upon drop off, unrequested. Now what? 🤔🤣

91% isn't 91% when you can't discharge to 0. Our usable capacity is in the middle of the available capacity, not the lower end.

Correct, but 91% full is still 91% full, and the buffer in the lithium-ion world is still 9%. Your reference is only to the 5% lower reserve below which Ford does not let the battery drop. It isn’t a specific physical part of the battery - just a software limit. Likewise the 9% cap reserve is just that too - a software limit, not a partitioned battery segment. It is the same as a tank of fuel. You can only “fill” it to 91% of the tank’s size, and cannot draw it below 5% of the tank’s capacity - there’s always something left when the trucks conks out.

A distinction without a difference. Our 100% IS the 91% to which Ford gives us access. The reality is that the battery is a tank. You can’t use the last 5% in the tank, and you can never top it off above 91% of its actual capacity. And when you get to 91%, the meter tells you that’s 100%. But we know that’s really 91% of the lithium battery’s tech. Other manufacturers run their max charges much closer to actual max battery capacity - Ford’s conservative approach guarantees fewer warranty claims, but also gives owners comfort that they have much less likelihood of either losing significant range, or damaging their batteries in the charging process.

I'm not going to argue with you anymore since you're adamant your right. I'll just point out that 91 - 5 = 86.

I wasn’t aware driving would reset the one-time limit. I don’t think it says that in the manual. I need to test that out.

Now that he’s charged there, using the location setting is probably the best solution.

Is t that why its termed “one-time”?

According to the manual “one time” means the next time you charge. It doesn’t say that driving before the next charge cancels it. If it does, its usefulness is quite limited.

Not much damage. But you can draw the battery down very easily - just set several departure times per day in the app and tell it you want the car "warm" for all of them. When you hit a safe and sane 90% charge, turn the departure times off.

thanks for all the input and info everybody.

wouldn’t this particular idea only work if the truck is plugged in the whole time it is parked?

I didn’t think the departure time setting worked if you were not plugged in ?

do I have that wrong?

otherwise this would seem like a brilliant solution. I could set 2 departure times a day and slowly drain down the battery a little bit over the 7 days I’m gone.

I’ll try it either way!

There's a Toggle in Ford Pass for allowing that on the last screen when you add your first Departure Time.

I thought that toggle was just for remote starting while unplugged,
not for preconditioning battery?

Speculation by some is that the amount of battery heating is reduced while not connected to shore power. Brings to mind an experiment I am going to perform today & Monday morning to see how much more (if any) a preconditioning cycle or two depletes the battery compared to just manually remote starting vs a timed schedule. Is there a substantial or minor difference ?

This is pretty ridiculous. If you run the truck sitting still, it barely uses any power.

You should stop focusing on this totally. The truck is fine. This is what's called an "irrational fear".

Assuming that a remote start or timed departure events occur 14 times over the next week, you will consume at least 14 kWh of energy based on this sample of one 15 minute remote starting session at the southern New England ambient temperature of 46°

This is the minute by minute energy consumption chart.

This is the hourly chart showing the kWh used, I suspect it will be about the same using the departure setting you have programmed.

Hopefully the airport parking attendant doesn't panic with seeing your truck illuminate periodically through the day's & week while your away, heck, he might proactively charge you up again prior to your arrival as a measure of good customer service.

It doesn't matter, deplete your battery (a little) is what you want to do, from your screenshot:

Note: Remote starting when your vehicle is unplugged may deplete your battery.

I do agree with the 'forget about it, stress kills' sentiments. But, as @TaxmanHog demonstrated, you can probably skim some battery charge off from where you are.

 

[RickLightning]

I'm laughing. Clearly you people haven't tried to do remote starts without driving the vehicle, or haven't read / remembered the manual...

Note: A maximum of two remote starts, or one remote start with an extension, are allowed. To reset the restart procedure switch the vehicle to on, then to off.

I prefer to charge my truck to 80% but I also realize the "90%" usable battery capacity is only ~80% of total capacity.

The issue I have is less about any cell damage and more about the extra time it takes to charge from 80-90 (roughly another 20 minutes). I don't understand why Ford hard-coded the default charge limit let alone setting it to 90%.

Every time I fast charge I have to adjust it down to 80. Does anyone know if this can be changed via FORScan?

The garage attendant might help him with that catch.............
