Design And Simulation of Low Power Charging Station for EV By Using Fuzzy Systems

Abstract

The depletion of fossil fuels and increased pollution has led to the invention of Electric Vehicles (EV). An Electric Vehicle requires an onboard charger (OBC) to charge the battery for its propulsion. The objective of this project is to present the design and simulation of unidirectional onboard charger that can charge the traction battery through the solar PV system Here, the OBC consists of PROJECT PUBLICATION PROJECT PUBLICATION PROJECT PUBLICATION converter and Buck type DC-DC converter to regulate the charging voltage and charging Current of the battery. And using fuzzy logic controller. A 210W charger is considered for the design with a lead- acid battery of nominal voltage of 48 V, 35 Ah. This paper presents a performance evaluation of a fuzzy logic controller-based solar photovoltaic (PV) fed low-power charging station for electric vehicles (EVs). The proposed system utilizes a solar PV array to generate electricity and a fuzzy logic controller to regulate the charging process of the EVs. The study investigates the effectiveness of the fuzzy logic controller in maintaining the charging voltage and current within the safe limits while also ensuring optimal utilization of the available solar energy.
