Abstract: The safety evaluation of battery systems is crucial to prevent thermal runaway in electric vehicles (EVs) and ensure their safe and efficient operation. This paper proposed a data-driven approach that utilizes real-world operational data to evaluate the safety risk of EV battery systems.
The existing difficulties revolve around effective battery health evaluation, cell-to-cell variation evaluation, circulation, and resonance suppression, and more. Based on this, this paper first reviews battery health evaluation methods based on various methods and summarizes the selection of existing health factors in data-driven methods.
This includes a thorough examination of battery safety issues at the material, cell, module, and system levels, offering cross-level assessment and mitigation strategies that enhance prediction accuracy and improve the interpretability of electrochemical system evolution.
Therefore, it is crucial to consider the safety and reliability of the “second life” of new batteries during their development and to integrate appropriate management and monitoring systems into the design . The development of new batteries also needs to address future recycling and reuse issues.
Expertise, combined with statistical methods, will likely be more effective in forecasting battery safety performance. These statistical features, illustrated in Fig. 6, offer accurate calculations based on deviations and outliers of pack-level cell behavior. This can highlight potential failures from seemingly minor details.
4. Metrics for safety evaluation In assessing battery safety, particularly in the context of preventing TR incidents, it is critical to establish robust and reliable metrics (Table 5) that provide consistent benchmarks across various battery technologies and usage scenarios.
