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.
Battery degradation is inevitable, and it will also affect various battery parameters, and the existing sensor fault detection and isolation (FDI) methods ignore this important factor [, , ]. Tran et al. took battery degradation into account and proposed a sensor FDI scheme based on a first-order RC-equivalent circuit model.
Herein, the development of advanced battery sensor technologies and the implementation of multidimensional measurements can strengthen battery monitoring and fault diagnosis capabilities.
Consequently, the fault diagnosis of lithium-ion batteries holds significant research importance and practical value. 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.
Thus, optical camera-based monitoring methods have found widespread applications in battery manufacturing for a fully automated defect detection process which is proven effective in reducing battery defect rates, making them promising for applications in large-scale battery energy storage systems due to their low cost and high scalability.
The integration of battery management systems (BMSs) with fault diagnosis algorithms has found extensive applications in EVs and energy storage systems [12, 13]. Currently, the standard fault diagnosis systems include data collection, fault diagnosis and fault handling , and reliable data acquisition [, , ] is the foundation.
