Research on Fault Diagnosis Methods for Lithium-ion Power Batteries
With the rapid development of new energy vehicles,the safety problems have become increasingly prominent.As an important part of new energy vehicles,power batteries are one of the focuses of the development of new energy ve-hicles,and there are still many development bottlenecks.Among them,the power battery system failure is an important part of the power battery safety problem,but also the government,enterprises and consumers are focused on the direc-tion,so the development of advanced power battery system fault diagnosis technology is of great significance,and strive to deal with the fault in the embryonic stage,laying the foundation for the vehicle to achieve safe and stable operation.This article firstly summarizes the fault types and manifestations of the battery system fault,analyzes the causes of the fault,and then summarizes the existing fault diagnosis methods,and gives personal suggestions,in order to provide a reference for the fault diagnosis of the power battery.
