Abstract

In order to improve the accuracy of the equivalent circuit model, on the basis of the second-order RC model, the effect of temperature on the hysteresis electromotive force is investigated and a temperature influence coefficient is added to the single-state model; the effect of temperature on the actual usable capacity of the battery is analyzed, and a correction coefficient considering the capacity loss is proposed. Finally, the dynamic current working condition is simulated and verified by experiments using the constructed model. The results show that the established model can fit the operating characteristics of the battery well, and the error with the experimental voltage is only about 20 mV, which is about 2.48% higher than that of the traditional second-order RC model.
