The application of TOPSIS in the study of the comprehensive performance of lithium-ion power battery

The performance of power battery has a significant impact on operational safety, efficiency and economy of electric vehicles. In this paper, we use TOPSIS to evaluate the performance of power battery. Through experimental modeling method we can get the parameters of Lithium-ion batteries and analyze the effects of these parameters on overall performance of the battery by using TOPSIS. The results show that the comprehensive performances we get through TOPSIS are consistent with experimental data, which indicates that it is accurate to evaluate the comprehensive performance of the battery by using TOPSIS.
