Each cell is operated in specific SOC window (say 70%DOD between 20 and 90 %SOC) which is matched to other aging mechanisms. So each cell has its own operational SOC region. Another cell might be used between 25 and 95 %SOC and another between 15 and 85 %SOC. Effectively reducing certain amount

This is why SOC windowing was developed. To compensate the 'death rate' among the cells in the pack. Works with high voltage chemistries but with LFP and LTO one must do 'other stuff'. -Jukka ke 9. elokuuta 2017 klo 22.01 Bill Dube via EV kirjoitti: > Self discharge has an

Self discharge has an _extremely_ strong function of temperature. http://batteryuniversity.com/learn/article/elevating_self_discharge It is also a function of cell health, age, past abuse, etc. The list of factors that alter the rate of self-discharge is seeming endless. Because it is such a
