Modern Approaches to Assessing the Technical Condition of Traction Lithium-Ion Batteries: Review Article
This review provides a comprehensive analysis of modern approaches to assessing the technical condition of traction lithium-ion batteries. It covers degradation mechanisms, compares model-based, data-driven, and hybrid diagnostic methods, and discusses future trends like cloud platforms and AI. The goal is to enhance reliability, safety, and durability of EV batteries, shifting from reactive to predictive maintenance.
Executive Impact at a Glance
Implementing advanced AI for battery diagnostics translates directly into tangible benefits for your operations.
Deep Analysis & Enterprise Applications
Select a topic to dive deeper, then explore the specific findings from the research, rebuilt as interactive, enterprise-focused modules.
Degradation is multifactorial, including electrical (C-rate, DoD), thermal (temperature, BTMS), and mechanical (vibration) stresses. These factors interact, accelerating capacity fade and internal resistance increase. Understanding these interactions is key for accurate diagnostics.
Approaches include model-based (ECMs, Kalman Filters) for interpretability, data-driven (ML/DL, RNNs, CNNs, Transformers) for complex patterns, and hybrid methods combining both. The choice depends on accuracy needs, computational resources, and data availability.
Promising directions involve cloud platforms for fleet-wide data analysis, digital twins for predictive simulation, and Explainable AI (XAI) methods like SHAP/LIME to enhance trust and interpretability in critical safety applications like EV battery management.
