Detection Method for Leakage Faults in Lithium-Ion Batteries …
Battery thermal runaway is a critical factor limiting the development of the battery industry. Battery electrolytes are flammable, and leakage of the electrolyte can easily trigger thermal runaway. Currently, the detection of leakage faults largely relies on sensors, which are expensive and have poor detection stability. In this study, firstly, the leakage behavior of lithium-ion batteries is ...

Research progress in fault detection of battery systems: A review
The battery overvoltage or undervoltage fault can be diagnosed using the threshold-based method. The voltage information collected by the voltage sensor is compared with the preset threshold. When the battery voltage exceeds the threshold, the fault occurrence state and fault occurrence time are defined [13]. Pre-processing the collected data ...
