Management of imbalances in parallel-connected lithium-ion battery ...
To meet the power and energy requirements of the specific applications, lithium-ion battery cells often need to be connected in series to boost voltage and in parallel to add capacity [1]. However, as cell performance varies from one to another [2,3], imbalances occur in both series and parallel connections.
3. Battery bank wiring
The maximum is at around 3 (or 4) paralleled strings. The reason for this is that with a large battery bank like this, it becomes tricky to create a balanced battery bank. In a large series/parallel battery bank, an imbalance is created because of wiring variations and slight differences in battery internal resistance.
