Optimizing Battery Use During Winter?

[srspring551]

Often (in cold weather) the Lightning will actually show an alert that recommends keeping the truck "plugged in" overnight. If you plan on setting a departure time or "remote" start, that should precondition cabin & battery.
As slightly different twist - In an interview, a Ford exec said that just keeping it plugged in overnight keeps battery temp above 0°C?
SOC interview:
Does the truck actually "pull" enough energy for that from any EVSE, without a departure set?

He also states that the "resting" battery loses about 1° (assume C) per hour. I would imagine that depends on size of battery and actual environmental temp (and wind) but it would be interesting to see graphs of that.

I have not noticed if the cabin air recirc is activated automatically in cold weather, as he says.

Also, does the grill aperture always close itself in cold weather, when you park and vehicle off?

Truth? BS?

Not that I know of, but there is one side of the building I haven't been on. I will look around next time and see.

Also look for utility sheds near by. I found outlets in back of buildings and where they store golf carts used for property management.

Also, suggest to the facility that they install some L2 chargers, hopefully at reasonable rates.

I feel the same way, I would charge to 100% when you’re making that trip. Maybe slow down to 65 mph. That may give you an extra few miles.

I've never seen the Lightning spontaneously draw energy outside the charging process, remote start or departure timed start, my Emporia Vue2 reports confirm my experience.

No. A remote start is NOT the same as a departure time, and NO, it does not precondition the battery.

I saw this with my Mach-E back during the winter of 2022. I haven't noticed it since with either the Mach-E or the Lightning, but if they tried during the day my JuiceBox settings would have prevented it. And, if you don't go looking for it, you never know it happened.

And here it is with the Lightning - https://www.f150lightningforum.com/...gged-in-last-night-because-it-was-cold.13544/

Thanks for the link to the other members observation, I stand by my assertion, never seen it and I do look at the log.

So that I understand - does a remote start (or getting in + starting the vehicle and just sitting there) warm the battery, or not? ... or must you be driving to generate battery warming? Thanks

I thought stating that in post #20 would be clear enough.

So, here's specific answers to your questions:

1) No, a remote start does not warm the battery.
2) No, starting the vehicle and letting it run does not warm the battey.
3) No, driving doesn't warm the battery for a LONG time.

There are three things that warm the battery quickly:

1) Setting a departure time while plugged in.
2) Navigating to a fast charger with the Ford Navigation, or with Android Auto and GoogleMaps.
3) DC fast charging. You'll leave 95 - 100 degrees F.

Great, thanks! I love summary lists since I often read ambiguity if I think of special case scenarios!
