Through the above analysis, the capacity of every single cell in the series–parallel battery pack is different, which causes the single cell to overcharge and overdischarge during the charge and discharge cycle, accelerating the aging of the single cell and causing the battery pack’s parameter difference to deteriorate.
The individual cells’ SOC difference of each branch of the parallel-connected battery pack is not stable, and variations in standing and drastic working conditions will result in the disappearance of individual cells’ SOC difference, which has little significance. The capacity difference of the individual cells is frequently not a single variable.
When there is a capacity difference between individual cells, the battery pack’s performance is determined by the individual cells with the smallest capacity. When there is a polarization difference between individual cells, the battery pack’s performance is determined by the single cell with the largest polarization degree. 3.1.2.
In addition to individual cells’ capacity utilization and individual cells’ energy utilization, individual cells’ terminal voltage is also an important indicator of the battery pack’s performance. The operating condition is set to discharge the single cell at a 1C rate and reaches the single cell’s discharge cutoff voltage.
The capacity utilization and energy utilization are used to evaluate the battery pack’s performance based on the above derivation results. When there is an Ohmic resistance difference between the individual cells, the individual cells with the highest Ohmic resistance limit the series-connected battery pack’s performance.
Furthermore, cell-to-cell variation and packaging elements are taken into consideration in the process of battery pack modeling for the model accuracy. The proposed modeling method of battery pack is verified with the help of simulation and experimental results based on Li-ion battery along with battery charger and discharger.
