Abstract	This study is research upon the over-potential of Li-iron batteries. By performing many cycles of charging–discharging experiments under controlled ambient temperature, adjusted depth-of-discharge, and discharging current rates, the dynamic voltage variation data is collected. A model based on the cubic over-potential differential equation is proposed. This model is able to predict the gradually prolonged time-constant dynamics of the battery loaded voltages with fewer parameters. By this way, a set of procedures is also proposed to adjust the parameters as the battery ages. The experimental result is used to verify the feasibility of this model. Even for the aged batteries, the prediction error is small and the result is satisfactory.
