Energy Management Strategies of PV-Battery/Supercapacitor System for Electric Vehicles

Abstract

The development of EVs (Electric Vehicles) as a zero-carbon alternative to fossil fuel-powered transport represents the importance of development in HESS (Hybrid Energy Storage System) and EMS (Energy Management Strategies). The present study focuses on a HESS model based on a parallel full-active configuration that integrates a (Li-ion) battery with a supercapacitor connected by two DC-DC bi-directional converters, are suitable options to power supply an electric vehicle. The EMS governing the HESS emerges as a critical element in the overall performance of EVs. The fuzzy logic control strategies have been widely used in high-level supervision and control; MPPT fuzzy logic is used for controller PV system. A complete study of the HESS; PV system, battery/supercapacitor is tested using MATLAB/Simulink. The simulation results show the performance and efficiency of the battery/supercapacitor for the EVs. Hence, the benefits of battery/supercapacitor use in a hybrid storage system are investigated and analyzed.
