The battery fault diagnosis method based on principal component analysis determines whether a fault occurs through the residual between the predicted and actual values. The original data matrix Xn m , as shown in (1). where n and m denote the number of samples and batteries, respec-tively.
In instances of an open circuit fault (OCF) in a series-connected battery pack, the voltage instantaneously collapses to zero, rendering the battery pack inoperable. Sun et al. used only voltage data to realize accurate diagnosis and localization of ESC and OCF in series battery packs.
Fault diagnostic algorithms are, hence, a requirement for BMS. These algorithms serve the purpose of detecting faults early and providing appropriate and immediate control actions for the battery and the users . Figure 2 illustrates the mechanism of fault diagnosis in the BMS. Figure 2.
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.
the internal resistance are considered as the fault features. In Ref. , the correlation coefficient between cell voltage s can capture the abnormal voltage drop. The entropy of battery temperature and voltage become the features of temperature abnormity and voltage fault, respectively.
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.
