| Abstract: | Lithium-ion batteries have received extensive attention as an excellent power source for new energy electric vehicles, and high-performance lithium-ion batteries are very important to the development of electric vehicles. Numerical simulation technology has overcome the limitations of traditional experiments and greatly promotes the research of lithium-ion batteries. Simulation models can couple multiple chemical reactions and physical fields, making it efficiently to predict the impact of various factors on the battery performance. And the biggest challenge for designing the battery models is to make the simulation results as close as possible to the real situation. Battery thermal model, perspectives of electrical model, the aging model and other models are applied in this paper to compare the simulation results about lithium-ion batteries. Besides, the advantages and disadvantages of each model are outlined. Furthermore, this paper puts forward the future developing trends of simulation: ① to explore the interaction relationship of multiple physical fields; ② to extend the applications of the models; ③ to improve the performance of battery materials and optimize the assembly method and the structure. |
