Modeling the power part of an electric vehicle based on a driving cycle

Nowadays, improving the power train of an electric vehicle, particularly an electric vehicle, is one of the major research areas in the field of transportation vehicles. Due to unstable load levels, frequent braking and acceleration, the efficiency of the power train needs to be improved using the latest components and techniques. The aim of the paper is to develop an efficient power train for an electric vehicle based on the world driving cycle. In this study, the existing driving cycles were analyzed and the most optimal one was selected based on its perfor mance under different operating conditions. As a result of the obtained calculations, the optimum power of a traction motor (TEM) was selected. Based on the selected power, the corresponding model of the motor is selected and its traction characteristics are built. In the MatlabSimulink software environment the modeling of traction drive, based on the driving cycle WLTC, is performed, the blocks of the model are presented and described mathematically, the dependencies a(t), E(t) and V(S) are obtained, which confirm the adequacy of mathematical modeling. An appropriate drive is selected in comparison with other models.
