The capacity loss of the battery pack is mainly composed of three parts. First, the capacity of the single cell cannot be fully utilized, resulting in inconsistencies capacity loss of the battery pack (marked as ΔCI ), which can be compensated through a conventional equalization method.
First, because of the inconsistent initial capacity and initial state of charge (SOC), the actual available energy of the battery pack is lower than any single cell; it will directly cause the loss of the energy density in group.
Pack Capacity is Determined by Random Cell-to-Cell Variations and Deterministic Thermal Offsets One explanation for the larger cell-to-cell variation in used EV battery packs is the non-homogeneous load that each cell receives in real-life batteries. For instance, imperfect cooling systems result in a thermal gradient along the battery pack.
The battery pack model with 96 cells in series is established. The influence factors of the consistency on battery pack are studied by simulation and experiment. The capacity loss composition of the battery pack is obtained and verified by the temperature variation experiment.
The inconsistency of the initial SOC and the initial capacity does not increase the battery capacity loss, and it was screened before in group, so it can be considered that the inconsistency has little effect on the inconsistency of the battery pack. Fig. 6 shows the capacity loss rate of the battery pack after 1000 cycles.
Practice shows that the consistency of the battery pack will experience a gradual deterioration process. In general, the inconsistencies damage to the battery pack life is more serious than that of the durability of the single cell.
