Three or four times now I’ve tried to see if scheduled charging would work if left overnight in the cold. Basically -10 C, scheduled charging for 5am, 50% SOC, set to charge to 80%. All four tests have failed to charge. I woke up this morning and checked it about 9am. Nothing was added and charging was off. Normally I just plug it in right away when I get home since the battery is warm already. I would like to have a fail safe if i forget though.
