Therefore, the most effective approach for Li-ion battery fault diagnosis should be a combination of both model-based and non-model-based methods. Table 1. Summary of Lithium-ion (Li-ion) fault diagnostic algorithms.
A battery management system (BMS) is critical to ensure the reliability, efficiency and longevity of LIBs. Recent research has witnessed the emergence of model-based fault diagnosis methods for LIBs in advanced BMSs. This paper provides a comprehensive review on these methods.
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
As the landscape of alternate energy methods for high technology and consumer goods such as, electric vehicles (EV) and bikes, smartphones and laptop advances, R&D is increasing to continually develop new types of batteries. In addition, QA/QC methods for lithium ion battery producers are also becoming more stringent.
Lithium-ion batteries (LIBs) have found wide applications in a variety of fields such as electrified transportation, stationary storage and portable electronics devices. A battery management system (BMS) is critical to ensure the reliability, efficiency and longevity of LIBs.
There has not been an effective and practical solution to detect and isolate all potential faults in the Li-ion battery system. There are several challenges in Li-ion battery fault diagnosis, including assumption-free fault isolation, fault threshold selection, fault simulation tools development, and BMS hardware limitations.
