My average battery temp the last month has been running around 45-48F or so depending on the time of day.
We actually had snow a week or two ago here.
But certainly its not THAT COLD around here in the winter.
Battery / BMS is continuing its 3 month adjustment, now down to 92.34%.
Doesn't the fact that (for some) winter shuts down the adjustments or the BMS tell us with certainty (AKA CONCLUSIVELY) that the LACK of thermal management is causing issues for the battery? why else would the BMS slow down adjustments when it is cold?
So we just need to keep the battery at about 20F and it would last forever....
Stop listening to what 24 and 30 kwh LEAFers have to say. Your pack is simply different. But the "real" difference is the BMS. Its simply reporting information using a completely different set of rules. I had my biggest negative adjustment happen during the coldest part of the year which coincides with the time of year I did least amount of driving (2717 miles in 3 months).
Then Summer came, I road tripped, cooked the pack, drove 4599 miles in 90 days, hit 12 temperature bars for the FIRST TIME EVER a few times. Did a QC compatibility test of Webasto which was 9 charging stops in one day exceeding 500 miles and my pack stats WENT UP.
With all that in mind; the real question becomes "how well do you think you can predict what your pack will do in the next year?"
You are at 92.30something % SOH? Well, that is about where I was after 21 months of ownership after being at 92.5% after 15 months...
But I am not alone. There are now dozens of us and we all seem to be between 15-21 months and 91 to 93% SOH. We live ALL OVER the World and have rampantly different driving habits, demands and needs.
A year is a long time; What do you think your SOH will be on July 4th?
