Résumé

This thesis addresses the modelling, estimation, and hardware development of a Battery Management System for a 60 V lithium-ion battery pack used in electric scooter applica¬tions. A Dual Polarization equivalent circuit model was selected for its balance of accuracy and computational efficiency, and was formulated in the Laplace domain to enable sta¬ble, real-time embedded implementation. State of Charge dependent lookup tables were constructed from Open Circuit Voltage and pulse-response data to capture nonlinear cell behaviour. An enhanced Coulomb Counting method with Open Circuit Voltage based drift correction was developed, and MATLAB/Simulink simulations confirmed close agree¬ment between model predictions and expected voltage responses under dynamic loading. To support future embedded deployment, a complete centralized Battery Management System hardware architecture was designed, including the STM32H563 microcontroller, the BQ76952 analog front end, current and temperature sensing circuits, MOSFET-based protection stages, and a compact 2-layer PCB. The thesis establishes a validated modelling framework and a ready-to-integrate hardware platform, forming the foundation for subsequent firmware development, prototyping, and experimental validation on a physical e-scooter battery system.
