Battery system faults can be categorized into three main types: battery faults, sensor faults, and connection faults. 3. Battery faults Battery faults are typically classified into three categories: overcharge, over-discharge, and internal or external short circuits.
In addition, a battery system failure index is proposed to evaluate battery fault conditions. The results indicate that the proposed long-term feature analysis method can effectively detect and diagnose faults. Accurate detection and diagnosis battery faults are increasingly important to guarantee safety and reliability of battery systems.
A schematic of fault diagnosis in the battery management system (BMS). In the battery system, the BMS plays a significant role in fault diagnosis because it houses all diagnostic subsystems and algorithms.
Electrical fault The electrical fault in the battery system is one of the most dangerous fault types. Meanwhile, it is the most common fault. The electrical fault mainly includes ISC fault, ESC fault, over-charge/over-discharge fault, insulation fault, sensor fault, communication fault, and contactor fault.
As electric vehicles advance in electrification and intelligence, the diagnostic approach for battery faults is transitioning from individual battery cell analysis to comprehensive assessment of the entire battery system. This shift involves integrating multidimensional data to effectively identify and predict faults.
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. At present, model-based fault diagnosis methods are still the hot spot of research.
