Fig. 8 shows the relationship between the battery pack capacity and the series cell capacity, taking a battery pack with three cells connected in series as an example. Battery pack capacity is defined as the maximum capacity of the battery pack that can be charged from a discharged state to a fully charged state.
Notably, the SOC and capacity estimations of the battery pack are essentially the estimations for the cell with minimum capacity. The cell with minimum capacity often has a minimum voltage, which is denoted by the “weakest” cell in the pack. However, the cell with minimum voltage could vary frequently due to varied external conditions.
