A study of cell-to-cell variation of capacity in parallel-connected
Given the inevitable initial cell-to-cell variation, understanding how this variation evolves over time, and how it may impact battery performance and degradation, is very important, particularly for applications involving large battery packs; e.g., so-called "second-life" battery packs with cells of different capacities for renewable energy applications [12,13].
Management of imbalances in parallel-connected lithium-ion battery packs
The effective capacity of lithium-ion battery (LIB) pack is reduced by the inconsistency of individual LIB cell in terms of capacity, voltage and internal resistances. Effective cell balancing scheme not only improves the charging and discharging capacity but at the same time it ensures the safe, reliable and longer operational life of the LIB pack.
