Therefore, efective abnor-mality detection, timely fault diagnosis, and maintenance of LIBs are key to ensuring safe, eficient, 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].
These abnormal changes can typically serve as features for early warning of battery failures [10, 11]. Therefore, the early and accurate identification of battery abnormality is essential for effective risk assessment and fault prediction [12, 13].
Power battery safety issues mainly involve thermal runaway, short circuit, over-charge, over-discharge, inconsistency, are often accompanied by abnormal changes in parameters such as voltage, current and temperature [, , , ]. These abnormal changes can typically serve as features for early warning of battery failures [10, 11].
Battery faults, which in-clude overcharging, overdischarging, overheating, external short circuits (ESCs), internal short circuits (ISCs), electrolyte leakage, swelling, accelerat-ed degradation, and thermal runaway (TR), are the most critical ones in a LIBS. These faults are also intertwined.
In the data-driven approaches, signal processing methods are mainly used for battery fault diagnosis, rather than machine learning-based methods. Sensor faults and actuator faults usu-ally affect the external signals of the battery, such as the voltage, current, and temperature.
In this paper, the state-of-the-art battery fault diagnosis methods are comprehen-sively reviewed. First, the degradation and fault mechanisms are analyzed and common abnormal behaviors are summarized. Then, the fault diagnosis methods are categorized into the statistical analysis-, model-, signal processing-, and data-driven methods.
