Abstract

The agreement on climate change which took place in France and Germany respectively in 2015

and 2017, show the international community's willingness to migrate from fossil fuels to green energy.

The development of electric vehicles plays a very important role in reducing the use of fossil fuels,

which have a detrimental effect on the ozone layer, leading to an alarming increase in the greenhouse

effect.

The electric machines are one of the basic technologies for electric vehicles because they ensure the

transformation of electrical energy into mechanical energy. Traditionally, the DC motor is the most used

for traction of electric vehicles due to the ease of its control. With the evolution of power electronics

components, AC motors specifically, the permanent magnet motor and the squirrel cage induction motor

have become more and more used machines in the traction of electric vehicles.

The Space Vector Pulse Width Modulation (SVPWM) is the most widely used because of its

multiple advantages such as the ease of harmony filtering, the ability to vary the fundamental output

quantities, and the permission of the power supply of several inverter assemblies, asynchronous motors

from the same continuous source.

In this article, we used a three-phase induction motor, a DC voltage source (lithium-ion battery) and

an inverter controlled by the SVPWM control technique to simulate and then predict the dynamic and

transient behavior of the induction motor for electric vehicle engine system.

The system has been simulated in Matlab Simulink. The simulation results show that the electrical

and mechanical behavior is satisfactory with a total harmonic distortion (THD) current of 3.53% and a

power range of 50kW. The results were obtained by simulating the operation at both no-load and underload.

The maximum current absorbed by the motor at no-load and at under-load is 5A and 40A,

respectively.
