Design and Implementation of Battery Management System for Electric Vehicle Charging Station

Abstract

Power is the crucial key for the commercial growth of any developing country. This paper represents the Battery Management System (BMS).This method to observe the battery inner process and ambient temperature, current, voltage and supervising the overcharging and deep discharging function. The State Of Charge (SOC) is most necessary criterion of the batteries, which reflects the battery accuracy and its status. In Mathematical modeling approaches Coulomb-counting method to estimate SOC of the battery is used during charge and discharge. The output from solar panel, battery energy storage system in both source side and load side are employed to charge an electric vehicle in charging station. If any emergency purpose power from grid is used to charge an electric vehicle. In this study, maintain the SOC of battery while overcharging or deep discharge beyond its limit in both source side and load side in electric vehicle charging station. The performances of the proposed method are evaluated through simulations using MATLAB/ Simulink software.
