A third-order reaction li-ion battery model

This paper aims to do researches upon the dynamic characteristics of loaded voltage of Li-ion batteries. Many cycles of discharging experiments are carried out under controlled ambient temperature and adjusted SOC, discharging current level to gather the dynamic varying voltage data. These data are employed to establish a novel battery model. This model is expected to be based on less parameters that would be functions of battery current and SOC. Experimental data is used to verify the accuracy of this model and the result is satisfactory.
