Resource Overview
Addressing the nonlinear, complex, and environmentally sensitive characteristics of lead-acid battery models, we implemented a third-order model for lead-acid battery modeling. The simulation results provide corresponding conclusions. We propose novel approaches utilizing "black-box" theory from artificial intelligence, neural network theory, and adaptive control concepts to resolve challenges in lead-acid battery simulation modeling. Key implementation aspects include MATLAB's Simscape Electrical components for battery parameterization and Stateflow for adaptive algorithm integration.
Detailed Documentation
During our research on lead-acid battery models, we identified their inherent nonlinear characteristics, structural complexity, and environmental sensitivity. To achieve more accurate battery modeling, we implemented a third-order model using Simulink's specialized blocksets, with parameter optimization through MATLAB's Optimization Toolbox. The simulation results yielded significant conclusions regarding battery performance under varying load conditions. Furthermore, we developed an innovative methodology incorporating artificial intelligence and smart control strategies—specifically "black-box" modeling theory, neural network architectures (implemented using Deep Learning Toolbox), and adaptive control algorithms—to address persistent challenges in lead-acid battery simulation. This new approach opens up additional research directions and possibilities for dynamic battery management system development, including real-time SOC (State of Charge) estimation using recursive least squares algorithms and thermal behavior prediction through neural network training.
