Battery faults represent a broad spectrum of issues that can occur in a battery system, significantly impacting its performance, safety, and longevity. These anomalies, often complex and multifaceted, range from minor deviations in battery operation to severe incidents, leading to catastrophic damage and failure.
Therefore, effective abnormality detection, timely fault diagnosis, and maintenance of LIBs are key to ensuring safe, efficient, and long-life system operation [14, 15].
