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.
These articles explain the background of Lithium-ion battery systems, key issues concerning the types of failure, and some guidance on how to identify the cause(s) of the failures. Failure can occur for a number of external reasons including physical damage and exposure to external heat, which can lead to thermal runaway.
Such problems are typically attributed to design flaws, component failures, and environmental factors. One of the most frequent causes of battery protection circuit failures is improper design. Even minor miscalculations in circuit design can have severe consequences.
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.
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.
Due to the diverse operating conditions of vehicles and the complex structure of battery systems, battery faults typically do not occur in isolation.
