What is a fault mechanism in a lithium ion battery?

Fault mechanisms LIBs suffer from potential safety issues in practice inherent to their energy-dense chemistry and flammable materials. From the perspective of electrical faults, fault modes can be divided into battery faults and sensor faults. 4.1. Battery faults

Are lithium-ion battery systems safe?

However, lithium-ion battery systems (LIBSs) frequently malfunction because of complex working conditions, harsh operating environment, battery inconsistency, and inherent defects in battery cells. Thus, safety of LIBSs has become a prominent problem and has attracted wide attention.

Are Li-ion battery faults dangerous?

However, various faults in a Li-ion battery system (LIBS) can potentially cause performance degradation and severe safety issues. Developing advanced fault diagnosis technologies is becoming increasingly critical for the safe operation of LIBS.

What are the different types of faults in a battery system?

This article provides a comprehensive review of the mechanisms, features, and diagnosis of various faults in LIBSs, including internal battery faults, sensor faults, and actuator faults. Future trends in the development of fault diagnosis technologies for a safer battery system are presented and discussed.

How fidelity and complexity affect battery fault diagnosis?

Given the intricate multi-layer internal structure of a LIB and the electrothermal coupling effect caused by faults, establishing a well-balanced battery model between fidelity and complexity poses a critical challenge to battery fault diagnosis.

Can a fault cause a battery voltage deviation?

Since battery voltage deviation caused by faults can sometimes be imperceptible, other deviations of battery variables such as SOC and capacity are proposed to effectively evaluate fault influence and provide a quantitative analysis of fault severity. 7.3.1. SOC difference
