Impact of Driving Style on Battery Life of the Electric Vehicle

Abstract

Electric Vehicles are becoming the future of the automotive industry and battery is the main component of Electric vehicles. The life span of the electric vehicle mainly depends on the performance of the battery which can be increased by the proper design of the battery management system (BMS). One of the factors that affect the battery performance and life span of an electric vehicle is the driving style. So, the supporting system to the BMS is developed that considers the effect of driving style on the performance of the battery. The system is implemented using MATLAB/Simulink tool which takes different driving cycles as input and obtained state of charge (SoC) as the output parameter. The main focus is to analyze the battery performance and its effect based on the different driving styles. The parameters like acceleration and deceleration account to determine the driving style like very aggressive, aggressive, and gentle. Finally based on battery capacity, the state of charge (SoC) is calculated for a different driving cycle. These observations are stored and analyzed to generate reports. These reports would be used to avoid the driving styles that are resulting in a decrease in battery performance and thus increases life span.
