AI Customer ServiceNevertheless, a battery pack is not equivalent to the sum of each single cell, and the principles of single cells cannot simply be implemented into a battery pack. Hence, it is necessary to model battery packs to study their characteristics after grouping the cells.
As told earlier when a battery pack is formed by placing the cells in series it is made sure that all the cells are in same voltage levels. So a fresh battery pack will always have balanced cells. But as the pack is put into use the cells get unbalanced due to the following reasons. SOC Imbalance
Similarly in the same case when the battery pack is being discharged, the weaker cells will discharge faster than the healthy cell and they will reach the minimum voltage faster than other cells. As we learnt in our BMS article the pack will be disconnected from load even if one cell reaches the minimum voltage.
The performance of a battery pack is determined by the cells it comprises. When the weakest cell gets exhausted in a battery pack, the capacities of the other cells are not fully utilized. Significant degradation in energy density, cycle life, and safety can occur with battery usage due to inconsistency among the cells.
In a huge battery pack like in EVs or solar arrays the cells are distributed over a waste areas and there might be temperature difference among the pack itself causing one cell to charge or discharge faster than the remaining cells causing an imbalance.
Moreover, a lithium-ion battery pack must not be overcharged, therefore requires monitoring during charging and necessitates a controller to perform efficient charging protocols [13, 23, 32, 143 - 147].
