Depending on the inducement, some lithium-ion battery faults are severe in the short term, e.g., ESC fault, while others are mild in the long term, e.g., ISC fault induced by lithium plating (LP). Therefore, researchers reviewed the lithium-ion battery fault diagnosis and early waring methods from the perspective of the fault warning stage.
Literature review Battery fault diagnosis involves detecting, isolating, and identifying potential faults in lithium battery systems to determine the location, type, and extent of the faults.
Measurement data Among the lithium-ion battery measurement data, voltage is widely used in fault diagnosis methods because of its simple acquisition, its ability to characterize the battery state, and its ease of distinguishing the lithium-ion battery fault type.
Lithium-ion battery data for fault diagnosis in different applications are comprehensively analyzed. Fault modes and diagnosis methods across application scenarios are reviewed. Fault diagnosis methods for both laboratory and real-world applications are summarized.
Our method can accurately identify all abnormal batteries in the dataset, with a false alarm rate of only 3.8%. The overall accuracy achieves 96.4%. In addition, we find that the widely used capacity-resistance-based methods are not suitable for identifying lifetime abnormality, which must draw enough attention from the battery community.
This work proposes a lifetime abnormality detection method for batteries based on few-shot learning and using only the first-cycle aging data. 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%.
