With the rapid development of the automobile manufacturing industry in various countries around the world and the improvement of emission standards in various countries, the rapid rise of the development of electric vehicles has aroused the great attention of governments and environmental protection organizations in the world. As an automobile country, China is also highly concerned about the development of electric vehicles. Endurance and driving safety are the main research directions of new vehicle performance. Electric vehicles replace traditional cars, the key point is to improve the performance of lithium batteries for vehicles. In the research of lithium battery performance, the accuracy of SOC estimation of lithium battery is an important content in the research of lithium battery. Accurate estimation of lithium battery SOC can improve the service life of lithium batteries and improve the charge and discharge performance of batteries.
