Uneven 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.
Cells are often connected in parallel to achieve the required energy capacity of large-scale battery systems. However, the current on each branch could exhibit oscillation, thus causing concerns about current runaway or even system divergence.
We show the parallel battery system to be essentially a convergent, stable, and robust system with a highly precise and absolutely reliable battery management system. The long-term trajectory of batteries connected in parallel in repeated cycles will be enveloped in a closed orbit insensitive to initial states of systems.
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.
If there are only two batteries in the parallel string, we would then take a cable from the POS. (+) terminal of Battery 1 to the charger. We would use the POS. (+) terminal of Battery 2 for connection to the loads.
Parallel systems without the E -SOC inconsistency can work well even with the negative trajectory slope. In summary, the parallel battery configuration generates inherent self-excited oscillation without requiring any external oscillating excitation, which raises concerns about stability within parallel battery systems.
