In addition, a battery system failure index is proposed to evaluate battery fault conditions. The results indicate that the proposed long-term feature analysis method can effectively detect and diagnose faults. Accurate detection and diagnosis battery faults are increasingly important to guarantee safety and reliability of battery systems.
Fault and defect diagnosis of battery for electric vehicles based on big data analysis methods Fault detection of the connection of lithium-ion power batteries in series for electric vehicles based on statistical analysis Simultaneous fault isolation and estimation of lithium-ion batteries via synthesized design of Luenberger and learning observers
Verified with the largest known dataset with 215 commercial lithium-ion batteries, the method can identify all abnormal batteries, with a false alarm rate of only 3.8%. It is also found that any capacity and resistance-based approach can easily fail to screen out a large proportion of the abnormal batteries, which should be given enough attention.
As electric vehicles advance in electrification and intelligence, the diagnostic approach for battery faults is transitioning from individual battery cell analysis to comprehensive assessment of the entire battery system. This shift involves integrating multidimensional data to effectively identify and predict faults.
The goal is therefore to develop methods with high sensitivity and robustness that detect abnormalities in the battery system even under dynamic load profiles and sensor noise. This work presents a novel data-driven approach to fault diagnosis based on a comparison of single cell voltages.
