Hybrid vehicles electric drive parameter calculation

Ovaj završni rad bavi se odabirom odgovarajućeg električnog pogona kojim bi se trebalo opremiti postojeći automobil s dizelskim motorom, a da se zadovolje prethodno odabrane performanse automobila prilikom korištenja samo elektromotora. U radu su navedene vrste hibridnih vozila. Opisane su sile i momenti koji utječu na gibanje automobila, te samim time opterećuju pogonski sustav (motor). Sile i momenti proračunati su na temelju karakteristika specifičnog vozila. Zbog pojednostavljenja proračuna napisana je skripta u programskom paketu Matlab, koja računa sve komponente momenta (otpor zraka, kotrljanja, nagiba puta, dinamički moment) koje se javljaju prilikom vožnje. Na temelju rezultata dobivenih Matlab skriptom odabrali su se elektromotori koji će moći ispuniti zahtjeve.This Bachelor Thesis deals with selecting appropriate electric drive which should be installed into existing car currently equipped with diesel engine, while achieving previously defined performances using only the electric motor. There are listed types of hybrid vehicles with description of each. Forces and torques that have influence on car movement and drive system (engine) are described. The forces and the torques have been calculated based on characteristics of a specific vehicle. To make parameter calculations simpler, there is script written in software package Matlab for calculating all the components of torque (air resistance, rolling resistance, grading resistance, dynamic torque) that occur while driving. Electric motors that will be able to meet the requirements were chosen based on calculations done by Matlab script
