PoF is not the only type of physics-based approach to model battery failure modes, performance, and degradation process. Other physics-based models have similar issues in development as PoF, and as such they work best with support of empirical data to verify assumptions and tune the results.
Li-ion battery failures. A critical step in this process is the understanding of the root cause for failures so that practices and procedures can be implemented to prevent future events. Battery Failure Analysis spans many different disciplines and skill sets. Depending on the nature of the failure, any of the following may come into play:
This enables a physics-of-failure (PoF) approach to battery life prediction that takes into account life cycle conditions, multiple failure mechanisms, and their effects on battery health and safety. This paper presents an FMMEA of battery failure and describes how this process enables improved battery failure mitigation control strategies. 1.
FMMEA-enhanced design and simulation tools can enable battery manufacturers to rapidly develop new batteries by assessing the impact of chemistry and design on performance and safety. Battery system designers will also benefit from life cycle simulation capabilities that include models for all relevant failure mechanisms.
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.
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.
