For the first time this winter the battery pack temperature in my Leaf hit 5 bars. I normally see the SOH% degradation slow down during the winters. Being curious as to where SOH was with warm-ish pack, I charged it up and gathered some data earlier than I normally do (typically the first of the month). It's amazing that it's dropped 3.57% SOH since the August 26, 2022. Data is clear that the degradation rate is happening faster as time/miles pass. In September I figured that the 4th bar would drop this summer. Now... I'm thinking this spring.
For a bit of context... Battery capacity bars dropped on dates in the red columns and the capacity loss per 5K miles was determined from the first full charge after the LBC software update that was performed on 6/20/2018.
