The damage caused by faults could be contained by the fault diagnosis and safety protection at all leve ls. With investigated. Various side reactions promoted by high -rate charging could c ontribute to accelerated degradat ion and TR. Moreover, faults especially for the ISCs that present the greatest potential threat to battery syste m safety.
One method to investigate battery fault and failure behaviors and mechanisms is to intentionally induce various abuse conditions, such as mechanical, electrical, and thermal abuse.
Global efforts by researchers and engineers in battery modeling and testing have led to the development of powerful tools for investigating battery behavior under abuse conditions [28, 29]. However, our ability to predict the risk of hazardous battery failure under realistic conditions remains limited .
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.
Recognizing the complex interplay of physical and chemical factors in battery failures is vital. An integrated approach, blending hardware and software solutions, is essential for advancing battery safety and ensuring a secure, sustainable future in diverse applications. 6.1. Comprehensive approaches to unravel battery failure mechanisms
