Such abnormal voltage data occur because the battery has experienced over-charging, over-discharging, imbalance, thermal runaway, and other faults [5, 6], causing voltage changes abnormally.

When a battery cell in the module experiences an ISC fault, the similarity between the voltage response of the faulty battery cell and that of the adjacent battery cells decreases, which is reflected in the reduction in the cosine value of the vector angle. The flowchart of the proposed diagnosis method is shown in Fig. 7. Fig. 7.

They may also be used for tasks beyond anomaly detection such as battery capacity degradation prediction. Fig. 1: EV dataset and challenges in fault detection.
Internal short-circuit (ISC) fault in battery systems is considered one of the most severe problems that can result in thermal runaway and fire [4, 5]. Therefore, studying detection methods of ISC and external short-circuit faults of batteries is very important to ensure safety in the lives of people and to avoid major accidents.
In a battery pack, a faulty cell may have a significant voltage difference from other normal cells, so the outlier approach is widely used to diagnose short-circuit faults. A fault detection method based on the transformation matrix and improved state-space model in the battery pack was proposed to detect fault batteries .
