A battery management system (BMS) is critical to ensure the reliability, efficiency and longevity of LIBs. Recent research has witnessed the emergence of model-based fault diagnosis methods for LIBs in advanced BMSs. This paper provides a comprehensive review on these methods.
Battery faults could lead to system performance degradation and even catastrophic accidents, such as bat-tery fires and explosions. BMS sensor faults will affect the normal operation of the control system, leading to inef-fective state estimation, equalization management, and thermal manage-ment in a LIBS.
This article provides a comprehensive review of the mechanisms, features, and diagnosis of various faults in LIBSs, including internal battery faults, sensor faults, and actuator faults. Future trends in the development of fault diagnosis technologies for a safer battery system are presented and discussed.
In battery system fault diagnosis, finding a suitable extraction method of fault feature parameters is the basis for battery system fault diagnosis in real-vehicle operation conditions. At present, model-based fault diagnosis methods are still the hot spot of research.
In , a review of sensor fault diagnosis for Li-ion battery systems was provided, but other types of faults were not discussed. Wu et al. conducted a review on fault mechanism and diagnosis for Li-ion battery, but there have been many new developments in the field since then.
A schematic of fault diagnosis in the battery management system (BMS). In the battery system, the BMS plays a significant role in fault diagnosis because it houses all diagnostic subsystems and algorithms.
