Simulation of the Movement of an Electric Vehicle in the Standard Cycle

Abstract

The paper presents a design and simulation investigation of a power train system used for battery electric vehicle. The proposed electric propulsion system consists of four independently driven in-wheel traction motors. Rear and front traction motors are selected with different power ratings for analyzing the energy efficiency of the drive system in various modes of operation under the driving cycle variations. The power management and control algorithm is proposed by means of a rule-based controller, which allows implementing the strategy of battery power distribution between the front and rear driving wheels. The power of the electric motors and the parameters of the battery are calculated and presented in this paper. The new European driving cycle is adopted as the motion profile, which is composed of the two European cycles (ECE15 and EUDC). The simulation of the entire power train system of battery electric vehicle is implemented using the AVL CRUISE software package. The modular construction of the program allows simple and convenient way to explore different vehicle configurations. The obtained simulation results show that the proposed power train system matches the design specifications of battery electric vehicle dynamic performance and allows solving the problem of economical energy consumption of the battery in order to provide the required driving range in the standard cycle.
