Liu et al. proposed a fault diagnosis and type identification method based on weighted Euclidean distance assessment and statistical analysis, which can effectively detect voltage inconsistencies in battery packs, and experiment results have demonstrated that this method has strong robustness and high accuracy.
To conform to such standards, the battery pack must pass safety tests such as the dielectric strength test, insulation resistance test, ground bond test, leakage current test…etc. In the industry, most companies use a single electrical safety analyzer to execute these safety tests.
Battery inspection techniques can identify process failures before defective cells leave the factory and provide a snapshot into manufacturing performance. In short, better inspection has a critical role to play in solving the battery quality challenge. A key consideration in inspection for battery quality control is which techniques to use.
Batteries go through an acceptance inspection before they are put together into modules and packs. This is because things like vibrations during shipping and even the passing of time can cause batteries to defect. It is necessary to keep the electrodes and enclosure (case), insulated from each other.
The variability and complexity of the real-vehicle process increase the difficulty of battery system parameter extraction. In battery system fault diagnosis, finding a suitable extraction method of fault feature parameters is the basis for battery system fault diagnosis in real-vehicle operation conditions.
The inconsistency fault can accelerate battery performance degradation and the premature fault of the battery system [124, 125]. In practice, battery status is monitored by sensors, so researchers usually classify the inconsistency into voltage inconsistency, temperature inconsistency, and SOC inconsistency according to the sensors types .
