Enhancing Electric Vehicle Performance and Battery Life through Flywheel Energy Storage System: Modelling, Simulation, and Analysis

This research paper focuses on the modelling and analysis of a flywheel energy storage system (FESS) specifically designed for electric vehicles (EVs) with a particular emphasis on the flywheel rotor system associated with active magnetic bearings. The methodology used simulation approaches to investigate the dynamics of the flywheel system. The objective of this study is to explore the effects of implementing the flywheel energy storage system on the performance of the EV. The paper presents a comprehensive model of the flywheel energy storage system, considering the mechanical and electrical aspects. The mechanical model accounts for the dynamic behaviors of the flywheel, including parameters such as rotational speed, inertia, and friction. The electrical model describes the interaction between the flywheel and the power electronics, such as the converter and motor/generator. To evaluate the benefits of the flywheel energy storage system, simulations are conducted. Simulation studies analyses the dynamic behaviors of the flywheel system under various operating conditions. The results demonstrate that the integration of a flywheel energy storage system in the EV powertrain has a positive impact on the battery life. By capturing and storing excess energy during regenerative braking and other driving conditions, the flywheel system reduces the load on the battery, leading to fewer charge-discharge cycles and slower battery degradation. This prolongs the overall battery life and reduces the need for frequent battery replacements. The research findings highlight the potential of flywheel energy storage systems as an effective solution for extending the battery life of EVs. By utilizing the flywheel system to manage energy fluctuations and provide additional power during high-demand situations, the strain on the battery is significantly reduced. This contributes to increased reliability, lower maintenance costs, and improved overall performance of EVs.
