An unbalanced pack or a pack with a cell which has a low capacity will correctly result in state-of-charge drift. In these cases, the BMS is working correctly since the battery pack has a reduced usable capacity. To resolve this, either the pack must be balanced (if out of balance), or the weak cell must be replaced (if caused by a weak cell ...
