Li-ion battery model exploring by intermittent discharging

This paper introduces a battery modeling technique for lithium-ion batteries. Repeated intermittent discharging experiments are performed on batteries for a lot of times, and followed by analyses on the battery terminal voltage curves to find an appropriate battery model based on circuit elements and the equations of the battery model parameters. The model is verified by simulating the battery voltages on discharge by different currents. Dynamic behaviors of the battery can be predicted by this model. Furthermore, real-time SOC estimation algorithm maybe developed by using this model.
