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.
Focus on Battery Management Systems (BMS) and Sensors: The critical roles of BMS and sensors in fault diagnosis are studied, operations, fault management, sensor types. Identification and Categorization of Fault Types: The review categorizes various fault types within lithium-ion battery packs, e.g. internal battery issues, sensor faults.
For battery system faults, the performance of the diagnosti c system will vary based on different diagnostic methods. A good evaluation system can compare various diagnostic algorithms and help design a better fault diagnosis method. The key to establishing evaluation methods . performance, di agnostic performance, and robustness , .
At present, the analysis and prediction methods for battery failure are mainly divided into three categories: data-driven, model-based, and threshold-based. The three methods have different characteristics and limitations due to their different mechanisms. This paper first introduces the types and principles of battery faults.
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.
The choice of algorithm depends on the specific context and criteria, making them vital tools for EV battery fault diagnosis and ensuring safe and efficient operation. Data-driven fault diagnosis methods analyze and process operational data to extract characteristic parameters related to battery faults.
