Simulation of effective electric vehicle power plant taking into account load cycles of motion

Abstract

The main problems of this study include an unstable load level, a large number of accelerations and decelerations, as well as a reverse operation of the traction motor. The goal is to develop an energy efficient drive based on the driving cycle to solve the above problems. In this work, an analysis of the WLTC driving cycle was carried out and its main characteristics were studied on the basis of test procedures under various operating conditions. The electric motor (EM) power is calculated based on the characteristics of the selected vehicle. Traction characteristics are built for various acceleration parameters and a specific engine model is selected. The traction drive was simulated based on the WLTC motion cycle in the “Matlab Simulink” software environment. The main model blocks are described and dependencies confirming the adequacy of mathematical modeling are displayed on oscilloscopes. A suitable energy storage device has been selected based on the battery comparison table. Ultimately, the power plant of an electric car was simulated taking into account the WLTC load cycle, under various input parameters and conditions.
