How to manage cell imbalances in a battery pack?
Cell balancing is often considered as the first option to manage cell imbalances in a battery pack. However, cell balancing in parallel connections requires cells to be connected through DC-DC or DC-AC converters, as shown in Fig. 13. The current of each cell can then be individually controlled.
What causes cell imbalance in a battery pack?
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].
What happens if a battery reaches a discharge cut-off voltage?
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.
How to manage battery imbalances?
However, there are simpler and more inexpensive solutions. Experimental case studies suggest that battery management of imbalances can be implemented by limiting the lower SOC level of a parallel connection below which the OCV decreases rapidly, and decreasing the discharge C-rates at the start of discharge.
Why is matched internal resistance important in a battery pack?
This phenomenon suggests that matching internal resistance is critical in ensuring long cycle life of the battery pack. Bruen et al. investigated the current distribution and cell temperature within parallel connections.
What happens if a lithium-ion battery is connected parallel?
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.
