This paper presents a method of detecting a single occurrence of various common faults in a Lithium-ion battery pack and isolating the fault to the faulty PCM, its connecting conductors, and joints, or to the sensor in the pack using a Diagnostic Automata of configurable Equivalent Cell Diagnosers.
Xu et al. (2024b) proposed a multi-objective nonlinear fault detection observer for lithium-ion batteries, developing a high-precision, three-step multi-fault detection scheme using adaptive thresholds for common fault detection.
Diagnostic algorithm is executed on a microcontroller and tested in real-time. Lithium-ion battery packs are typically built as a series network of Parallel Cell Modules (PCM). A fault can occur within a specific cell of a PCM, in the sensors, or the numerous connection joints and bus conductors.

Electric vehicles are increasingly popular for their environmental benefits and cost savings, but the reliability and safety of their lithium-ion batteries are critical concerns. Current regression methods for battery fault detection often analyze charging and discharging as a single continuous process, missing important phase differences.
The diagram illustrates various fault characteristics of a lithium battery. Oc represents the open circuit fault, Sc represents the short circuit fault, while Sm and Cf correspond to the sensor malfunction and connection fault characteristics, respectively.
