The equivalent circuit of lithium-ion battery cell has been presented in some research to model a state of charge (SOC) and battery cell electrical behavior. The equivalent circuit was built from an open circuit voltage, two resistor-capacitor parallel networks, and a series internal resistance. In several application, some battery cells are connected in series-parallel configuration to produce a battery pack with specified voltage and capacity. In this paper, a modified battery cell model is used to represent the battery pack dynamics. The battery pack is assumed to be balanced on both series and parallel side. The model then validated by comparing simulation results between battery pack model and battery cells that connected in series-parallel configuration. Simulation results shows small difference between the two models.
