The reliability and efficiency of the energy storage system used in electric vehicles (EVs) is very important for consumers. The use of lithium-ion batteries (LIBs) with high energy density is preferred in EVs. However, the long range user needs and security issues such as fire and explosion in LIB limit the widespread use of these batteries.
A LIB failure is caused by electrochemical charge-discharge instability . Therefore, understanding the electrochemical reactions and the material properties is essential for battery safety assessment. Voltage, temperature and cathode material are the factors that control battery reactions .
With the increase in vehicle running time and the uncertainty of operating conditions, the vibration, corrosion of components, and expansion of battery gas production can trigger the failure of internal connection components of the battery system, such as loose nuts or welding joints and poor contact [46, 48].
However, various faults in a lithium-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. This paper provides a faults, and actuator faults.
