WetEV said:The fact that simply driving more seems to improve lifetime suggests to me that a firmware change could make a large difference in battery life. Not if the OEM can prove that Nissan's other electronics is shortening the life of the batteries.
What specifically in a BMS's electronics, e.g. bleed-off voltage set point, or in its microcontroller's firmware could be contributing to increased
battery degradation? Surely, most OEM battery suppliers would be involved with each end-users BMS development team to define parameters
to avoid problematic issues, e.g. battery degradation. If not, the supplier potentially becomes involved in future liability issues and puts future
battery sales at risk.
