## Abstract

Objectives: To calculate the energy performance of the Electric Propulsion System (EPS) using the mathematical simulation and analysis of the obtained characteristics, taking into account the use of various types of electric motors. Method/ Statistical Analysis: The method of model-oriented programming was used to study the necessary parameters, by which the two mathematical models in Matrix Laboratory (Matlab) / Simulink were built. It allowed the calculations in a short time and a detailed analysis of the results. While building up the mathematical models of electric motors, the vector control was implemented, as based on the method of vector representation in variables of states in a space (Field oriented control). Findings: In addition to mathematical description of the motors, the article represented the mathematical model of the inverter on IGBT transistors required for commutation of the traction motor, lithium-ion battery as well as all major components required for proper system operation. This article discusses two of the most often used type of contactless AC machines - asynchronous motor with squirrel-cage rotor (Induction motor) and a synchronous motor with permanentmagnet excitation (Permanent Magnet Synchronous Motor). Because of mathematical simulation, the assessment of the energy parameters of two systems was carried out. Analysis of the obtained results allowed the identification of characteristic points in driving cycle, defining the minimum requirements for mechanical, electrical and power parameters of the electric propulsion of the electric vehicle on condition of implementation of the cycles reviewed. Because of the traction and energy calculation, the consumption values of electric energy for the electric power source were obtained, including the amount of energy regeneration. Application/improvement: These methods of mathematical models are universal and can be applied to various types of transport, from electric vehicles to electric trucks and electric buses.
