This is some data from last night and this morning:I ran the battery rather low so I did charge until 8:00PM before unplugging for the night. At that time the Battery temp was at 7C and the SOC DIC was 60.39%.This morning (~7AM, 25F outside) the battery temperature was at 3C (37.4F) and the SOC DIC was 60.00%.The 3C is above the temperature that it appears to heat to when charging (2C) so it didn't get cold enough to prove if it heated or not when unplugged. I can only think the battery may have been so heat soaked that it couldn't cool down enough to verify this.It was interesting to see that the SOC DIC % dropped but the amount was so small I think this will be inconclusive in showing any battery conditioning in cold weather while unplugged until I can get the temperature to drop low enough and see if I can repeat the results.Another thing I wanted to point out was that this morning my 12V battery was at 12.5V before plugging in and when I did plug it in it jumped to 13.6V, I believe this shows that the 12V battery gets charged up every time the car is plugged in and charging not just when it is turned on.
