Range estimation of battery electric vehicle by mathematical modelling of battery’s depth-of-discharge

Abstract

This paper presents the mathematical modelling of Battery Electric Vehicle (BEV) based on the depth-of-discharge (DOD) for range estimation of the vehicle using MATLAB/Simulink software. In this scheme, the lead acid battery and lithium ion battery are considered for depth of discharge computation and the range is estimated for the Simplified Federal Urban Drive Cycle (SFUDC) and European urban drive cycle. The analysis comprises with the tractive effort, machine and accessories losses are accounted. The potential values of the BEV are assessed with design, type and parameters of the vehicle. The complete mathematical model is simulated and the comprehensive results are tabulated.
