Cell Reversal in Lithium-ion Batteries
a) Unbalanced cells: Cell reversal can be caused by the presence of weaker or unbalanced cells within a lithium-ion battery pack. When a weak cell reaches its discharged state before the others, it continues to discharge, causing its voltage to drop below zero. The stronger cells in the series force the weak cell to reverse its polarity.

How to repair an already unbalanced Li-ion battery pack
Oct 27, 2021. How to repair an already unbalanced Li-ion battery pack. PACK after the life of the lithium-ion battery pack will be a lot more than the single lithium-ion battery section, this is because of the difference in the body of the single battery, as well as the subtle differences in charge and discharge environment, after multiple charging exacerbated …
Unbalanced discharging and aging due to temperature differences among the cells in a lithium-ion battery pack …
When the discharge process approaches the voltage turn point of the battery pack, the discharge current through the cell at higher temperature begins to decrease significantly. After the DOD reaches approximately 90%, the discharge current of the cell at higher temperature rises again.
Effects of Temperature Differences Among Cells on the …
This work aims to make a comparative analysis of the unbalanced discharging phenomenon for battery packs with series/parallel configurations due to the temperature differences among the cells. A theoretically-based model is developed for the battery pack and constant power discharging processes are simulated by the model.
