AI Customer ServiceVarious faults may occur at each cell or the associated accessories in battery pack due to the natural aging and various (including mechanical, electrical, and thermal) abuse manoeuvres in actual usage of EVs [5 - 7]. Unchecked faults would have great impacts on battery, or even lead to battery thermal runaway under extreme conditions .
Without proper fault diagnosis and early warning methods, a small fault may lead to serious damage to the power battery and even the electric vehicle [ , , ]. Therefore, it is very important to carry out effective diagnosis and give early safety warnings before serious battery failure.
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.
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.
Connection faults, cooling system faults, controller area network bus faults, etc. belong to this group of faults. Due to the need for a high level of energy in EV applications, the battery system usually consists of many battery cells connected in a parallel–series configuration.
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.
