Modelling and Performance Analysis of Battery Thermal Management System for Electric Vehicles on MATLAB/Simulink

Abstract

The battery pack in an electric car plays a vital role in converting direct current (DC) from the battery into alternating current (AC) to power the induction motor. It is a complex arrangement of batteries connected in series and parallel to meet the power requirements of electric vehicles. A Battery Management System (BMS) is employed to ensure safe and efficient operation. The BMS oversees and regulates the battery's performance by monitoring and managing voltage, current, temperature, and state of charge. This prevents any parameters from exceeding safe levels, ensuring the longevity and safety of the battery. The Battery Thermal Management System (BTMS) involves monitoring the temperature of the battery packs and initiating the cooling process when the temperature rises. This prevents excessive heat that could lead to component failure. MATLAB/Simulink is used to develop BTMS that analyze and compare temperature and state of charge parameters with and without the integration of a cooling system connected to the battery pack, aiming to improve battery pack performance.
