Modeling and Performance Analysis of Battery Electric Vehicle

Abstract

The emissions from vehicles have been a serious issue since the last century. To curb this problem, research in the field of automobiles gained momentum and the best alternative found is promoting usage of electric vehicles, in particular battery electric vehicles (BEV). Modeling of EV helps to carry out an in depth analysis before developing a real time model. Here, the mathematical model of BEV is developed in MATLAB/Simulink environment and is tested for different standard drive cycles for analyzing the performance. Fuzzy logic control (FLC) is used to decide the regenerative braking component so that the battery remains in safe operating conditions. For analyzing the importance of driving pattern, the urban and highway driving cycles are considered separately. The effects of variations of the vehicle parameters like weight and the road conditions like rolling resistance, road gradient and driving pattern are evaluated.
