DYNAMIC SIMULATIONOF BATTERYSUPERCAPACITOR HYBRID ENERGYSTORAGESYSTEM FOR ELECTRICALVECHILES

Abstract

The integration of battery and super capacitor energy storage systems offers significant advantages for electric vehicles (EVs), including improved power delivery, enhanced efficiency, and extended battery life. This paper presents the dynamic simulation of a hybrid energy storage system that combines batteries and super capacitors to meet the varying power demands of EVs. The proposed system optimizes the energy exchange between the two storage units, leveraging the high energy density of the battery and the high power density of the super capacitor. An Pi controller (PI) is employed to control the battery's charging and discharging cycles, ensuring optimal power management and efficient energy utilization. The PI-based controller adapts to varying driving conditions, optimizing the split of energy between the battery and super capacitor to enhance performance, minimize energy losses, and prevent overcharging or deep discharging of the battery. The dynamic simulation results showcase the effectiveness of the PI controller in managing the power flow, providing smooth transitions between the battery and super capacitor, and ensuring longer battery life. Simulation results confirm the benefits of the proposed hybrid system, demonstrating improved over all efficiency, faster response times, and reduced wear and tear on the battery compared to conventional energy storage solutions. This approach contributes to the development of advanced EVs with better performance, longer range, and greater energy efficiency
