Simulink Simulation Model for Lead-Acid Batteries

This article demonstrates how to create a detailed lead-acid battery simulation model using Simulink. The model accurately simulates state transitions during battery charging and discharging processes, incorporating key parameters such as internal resistance, capacity degradation, and thermal effects. Through simulating battery charge-discharge states, engineers can better understand performance characteristics and behavior under various operating conditions. The implementation typically utilizes Simulink's electrical components library and custom Stateflow blocks to model electrochemical reactions and aging effects. This simulation approach is particularly valuable for researching and developing new lead-acid battery systems while optimizing existing systems through parameter tuning and scenario testing. The model structure may include SOC (State of Charge) calculation algorithms, voltage-current characteristic curves, and temperature compensation modules to enhance simulation accuracy.
