A new type of electric double layer supercapacitor model advanced 2RC model was presented. The model was consisted of three branches including the instantaneous one, the voltage self-adjusting one and the self-discharge one, the influence of the temperature and the terminal voltage on the super capacitor operating characteristics were taken into consideration. The nonlinear feature of the charging, and process of the voltage and its recovery characteristics after the charge or discharge were described accurately. On the basis of the detailed description of the model structure, a set of identification methods was proposed to quickly determine the model parameters through constant current charging experiments, which had a strong engineering practicality. Final y, this model was applied to the super capacitor voltage equalizing circuit design and the single flying capacitor method was adopted as the voltage sharing strategy, which have achieved good results.
