MME Plugged-in overnight cold power usage and 12V LVB

[louibluey]

Here is another example for Louibluey overnight, -10F overnight, possibly warmer in the unheated, but closed garage (little insulation, no fiberglass, open at peak vent). I opened the car at 1:38pm Jan 21 to turn updates on, Fordpass said it wanted to do that latest one, 2.3.0. It did not report done this morning. For, me, there were two L1 charger events, 3:41 am (8.5kW) to 3:59 am (7.6kW) 2.3 kWhr, and 10:04 am (8.3 kW) to 10:18 am (7.6 KW) 1.7 kWhr for 4 kWh total so far today. There was a strange jump in LVB soc after 6 am Jan 22, much larger than the actual LVB charge indication before an after, odd. MME woke for some reason twice after the 20:24 mark, probably lights on, at least that first .4V+ drop.

Different/ strange behavior today. I left my MME plugged in overnight again and zero pulls for power. I had just taken a 220 mile round trip over the weekend and it was a little bit warmer last night, right at or below freezing.

Today MME is pulling a constantly low amount of power (1.17 kWh over almost 3 hours). Went out and turn on to accessory mode and back off to see if anything was “stuck “ running and also confirmed nothing plugged in to USB or cigarette lighter outlets. Figured I’ll just let it run as it’s not much power draw. Only guess would be a different sort of LVB conditioning than the behavior I saw when it was colder.

Interesting. 1.6 amps it not much. I have found preconditioning comes on around and under 10F. I have not seen it activate above 10F.

Seems to have completed whatever it was doing. It got about 40F as a high today as well. Another mystery!

Another mystery for sure. @Shayne reports 8 hours of continuous L2 power yesterday, of course it is much colder up in Northern Canada.
