- Interest on electric vehicles (EVs) has significantly increased from last decade, as whole world is concerned on reduction of emission of greenhouse gas by reducing the use of fossil fuel in transportation. The primary issue for electric vehicles is to develop an energy storage system i.e battery that can enable high mileage, rapid charging, and high-performance driving. Hence, battery management is required to get maximum, safe, and consistent performance of an electric vehicles when running in a variety of conditions. To get the most out of a battery, it's important to keep an eye on its operating conditions, especially temperature, which has been shown to have a direct impact on battery performance and life. So, battery thermal management system (BTMS) is crucial in control of the thermal behaviour of battery. In this study, we built and simulated one of the popular BTMS system using MATLAB/Simulink which uses phase change material (PCM) for colling and known as PCM colling system. The specification of battery and BTMS system is selected based on the case study of popular electric vehicles in the market. The simulation result shows the battery temperature variation and energy consumption at various operating conditions of vehicle. Moreover, we also investigate the effect of phase change material on battery temperature variation at different conditions. The required mass of PCM for optimal performance of BTMS is also proposed. The simulation result shows that for an electric car, BTMS is very crucial for management and control of thermal behaviour of battery. For the more comprehensive and precision study of the thermal behaviour of battery, this study proposed further investigation to be made using computational fluid dynamics models and thermo-electric models using openFOAM.
