To overcome these challenges, the proposed work introduces a novel framework for range estimation while integrating an enhanced equivalent circuit model with a physics-guided temperature-compensated Extended Kalman Filter algorithm. Firstly, comprehensive mathematical models are developed and validated that integrate: (i) proposed enhanced 3rd-order equivalent circuit modeling (p-eTECM) with control parameter optimization, (ii) data-and-model-driven parameter identification using Coulomb counting and voltage scaling analysis, (iii) comprehensive sensitivity analysis to rank important parameters to improve accuracy, and (iv) application-specific model selection criteria based on performance trade-offs. However, unlike existing frameworks that incorporate higher-order RC models that are universally superior, the proposed work identifies that model selection should be application-dependent for different battery management functions. The novel contributions include: parameter &amp; voltage optimization from the pack-level, while systematically eliminating voltage bias through online parameter optimization, and developing a comprehensive sensitivity analysis algorithm to validate the improvements. The proposed framework demonstrates that parameter calibration is more crucial with capacity correction and voltage scaling, to eliminate systematic biases that render models impractical. This study further reveals that 3rd-order model outperforms in voltage prediction (8.3 % improvement) while the 2nd-order model provides better SOC tracking (13 % improved accuracy), establishing clear application-specific selection criteria.

These outages disrupt economic activity and impact energy efficiency and sustainability goals by necessitating less efficient backup generation and hindering the integration of renewable energy sources. This paper introduces a pioneering, explainable Graph Neural Network (GNN) framework for edge-level transmission line failure prediction, addressing a critical gap in grid resilience analytics. Our work presents two key innovations: first, it is the first framework of its kind to be systematically validated across four standard power grid benchmarks (IEEE-24, 39, 118, and the UK grid), demonstrating robust generalization. Second, it advances an interdisciplinary approach by uniquely integrating network science principles with deep learning, augmenting traditional electrical data with topological descriptors like betweenness centrality and load ratio. This fusion enhances the predictive power of three GNN architectures: GINE, GAT, and EdgeAwareGC. On the IEEE-24 test system, this integration boosts macro-F1 scores from 0.498 to 0.871 for EdgeAwareGC and from 0.335 to 0.859 for GINE. This scalability and effectiveness are further demonstrated on the highly imbalanced IEEE-118 network, where EdgeAwareGC achieves a strong F1 score of 0.553. Explainability techniques such as gradient-based attribution and GNNExplainer uncover key physical and topological predictors, providing actionable guidance for grid operators. Our findings inform grid modernization policies, supporting initiatives like the U.S. Department of Energy’s Grid Resilience and Innovation Partnerships (GRIP) program.
