Saturday morning, no overnight or early morning spontaneous battery conditioning, again temps were in the low 20's overnight, what changed? I had not planned to drive the Lightning today, I had eliminated the Saturday afternoon departure time, that normally runs while the truck is off-plug sitting in the drive after morning coffee run.
It seems the trucks BMS logic noted my lack of planning to drive according to a particular schedule and didn't bother warming the battery at all, I'm certain all residual heat in the pack had bled off as yesterday afternoon when I parked her it was already showing limited power to motors at 92%, at an SOC of 57%, of course being that low the motor reduction is not uncommon even in warmer temperatures.
Here is the interesting event, plans changed for the day, I'll be taking the mrs. to church in the afternoon planning to leave the house at 3:45, so I decided to program a departure time to be ready at 3:35, knowing it'll prepare the battery earlier and warm the cabin 5 minutes prior through 10 minutes after appointed time.
As soon as I saved the plan, the truck immediately started battery conditioning, only a short stint of 11 minutes as we have seen in prior days, the cabin warming didn't occur, you can tell it's not happening when the animated fan icon is not active.
This is the energy flow for the event, 1.76 kWh to touch up the battery heat.
I'm going to let DT run full effect later this afternoon, to prepare the battery for full weekly charging, we will be driving the Mrs. car all day Sunday to give her a good work out, it's been 2 weeks since driven.
