Battery pack discharge voltage fluctuation

Cells with high SOC reach the charge cut-off voltage first, whereas cells with low SOC reach the discharge cut-off voltage first in the battery pack. However, even in a normal case, because the cells that reach the charge/discharge cut-off at any given point are different, the difference between the curve points is used to determine whether …
