What are common battery failures? Positive Plate Active Material Softening / Shedding & Corrosion . The discharge and charge process cause first the expansion, then the contraction of the positive (+) active material. Expansion occurs both in the plane (height and width) of the plate as the grid is pushed/stretched by corrosion processes over time and in the thickness of the

In this paper, the fault diagnosis of battery systems in new energy vehicles is reviewed in detail. Firstly, the common failures of lithium-ion batteries are classified, and the triggering mechanism of battery cell failure is briefly analyzed. Next, the existing fault diagnosis methods are described and classified in detail.
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.
Table 1. Faults performance of the battery system and interrelationships. Mechanical deformation, Over-charge/Over-discharge fault, induction of active materials, thermal fault. It is often accompanied by discharge and exothermic, and the main fault activates BTR. Connection fault, mechanical deformation, aging fault, water immersion.
Among battery thermal faults, the most common fault is excessive temperature, which can cause significant damage to the battery unit and the entire system. Thermal faults in battery systems, their consequences, and suggested remedies are outlined in Table 4.
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.
Faults can also be classified by performance: overcharge, battery thermal runaway, dendritic lithium, current-collector dissolution, and gas evolution . Tran et al. categorize faults into internal and external types, including internal short circuits (ISC), external short circuits (ESC), and over-charge/over-discharge faults .
