AI Customer ServiceUneven electrical current distribution in a parallel-connected lithium-ion battery pack can result in different degradation rates and overcurrent issues in the cells. Understanding the electrical current dynamics can enhance configuration design and battery management of parallel connections.
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 . However, as cell performance varies from one to another [2, 3], imbalances occur in both series and parallel connections.

Once one individual cell in a series connection reaches the discharge cut-off voltage, the entire series connection will stop discharging. Thus, many cells are never fully charged or discharged, and the available capacity of the battery pack is subject to the minimum capacity of the individual cells.
In addition, the position of cell in battery pack also causes cell imbalance due to the differences in heat dissipation and self-discharge [15,16].
The features of cell balancing in parallel connections are summarized. Recommendations of reducing cell imbalances in parallel connections is proposed. Uneven electrical current distribution in a parallel-connected lithium-ion battery pack can result in different degradation rates and overcurrent issues in the cells.
