Stop Me If You've Heard This One

[OCSTEVE39]

So far, I've only had the level one home charger.
I use departure times as often as I can, and seemed to work just fine back when I had the Mach-E. When we got the Lightning Flash three months ago, I continued the same charging practice of using departure times with the occasional prestart for unplanned trips.
After "cabin temperature is read" I get in, start the truck, and watch in horror as my soc drops 3%, tick tick tick, before even putting into drive (it's a chilly morning). Well, isn't that interesting? Guess I'll need to keep that in mind, huh? Fast forward to this pass Friday. Its bank run day, I'm in the office (home office) and as is my habit, I have opened the app to verify preconditioning has started. It has and lay the phone down while readying everything for my departure when our office manager (chewy, 3-year-old Mackerel possessing a 1K year old soul) decided he simply must be on the other side of the counter, stepping directly on the pre-start button as he went. OK, guess we are going with that. Time to go, I step in, start the truck, and the soc is steady. I look at it a moment longer. No movement? Not a tick? I put it in drive. No tick? I take off. Hit the bank, take the long way around to get back (of course) about five miles total. I get back, having used only 3% entire trip! Did you stop me? Ever heard of such? I'm testing it again tomorrow!

Do you use a level 1 charger?

Your level one charging doesn't have the ability to fully support battery conditioning on the Lightning, but if the truck ~thinks~ it can run the PTC heater, which draws 9KW, that will draw down the high voltage battery (HVB) by about 2 to 3 kWh depending, that's not worth 3% but it is still a net loss.

Using only remote start spontaneously just before leave time, the average amount of energy used is only about 1.5 kWh, barely enough to drop the SOC ~1%, that's what I usually see.

100%
It was surprising how hitting pre=start when chewy did lol, it stabilized the soc.

It's your level 1 charging. Normal behavior.
