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.
What are the features of cell balancing in parallel connections?
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.
Can electrical current dynamics improve configuration design and battery management?
Understanding the electrical current dynamics can enhance configuration design and battery management of parallel connections. This paper presents an experimental investigation of the current distribution for various discharge C-rates of both parallel-connected LiFePO 4 and Li (NiCoAl)O 2 cells.
How does current distribution affect cell balancing in parallel connections?
The dependence of current distribution on cell chemistries, discharge C-rates, discharge time, and number of cells is presented through experimental studies. The features of cell balancing in parallel connections are summarized. Recommendations of reducing cell imbalances in parallel connections is proposed.
Does connecting more cells in parallel prolong a pack's lifetime?
The range of cell capacity variations in each group was the same. By looking at the current gradient between cells, they concluded that connecting more cells in parallel can reduce the probability of inconsistency and thus prolong the pack’s lifetime.
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.
