Living in a temperate climate (to the cold side) and never doing long road trips, I will most likely never see too high of a temperature on my batteries. However, we do often get freezing temperatures in the winter, down to -10-15 deg C. Contrary to common belief, lithium plating does not magically start below the freezing point; it simply get worse and worse with lower temperature and higher current and SoC.
I obviously want to reduce the degradation of my battery as much as possible, so I generally L1 charge (6A@230V => 0.03C) right after coming home between 45 and 60% SoC, however even though the batteries are the warmest at this point in time, they are still below the freezing point at the moment.
As far as I understand most Leafs have a battery heater, but it only turns on a very low temperatures (-25 deg C?) which - for me - may happen once every 5 years.
Is is possible to hack this heater to heat the battery in general low temperature weather?
