Due to the existence of the coupled and complicated side reactions throughout the entire battery service life, battery would endure continuous performance degradation such as capacity fade and internal resistance increase. Furthermore, manufacturing defects and maloperations may lead to accelerated aging.
Therefore, effective abnormality detection, timely fault diagnosis, and maintenance of LIBs are key to ensuring safe, efficient, and long-life system operation [14, 15]. Battery fault diagnosis can assess battery state of health based on measurable external characteristics, such as voltage and current [16, 17].
