Abstract

Prvi dio diplomskog rada prezentira realne energetske komoponente sustava električnog vozila uz detaljnu teoretsku podlogu za modeliranje. U nastavku je realiziran Simulink model električnog automobila temeljen na ZESA električnom automobilu uz programski sustav za minimizaciju i dimenzioniranje energetskih elemenata. Opisan je postupak za prilagodbu modela na ZESA automobil na kojemu su izvršena ulazna mjerenja i koji je korišten za verifikaciju modela. Izvršeno je mjerenje linearne brzine i momenta na kotaču tijekom odabrane rute vožnje. Testiranje računalnog sustava provedeno je na temelju unosa navedenih podataka u modelirani sustav uz očekivanu minimizaciju energetskih komponenti ZESA vozila. Zbog problema pri mjerenju momenta na kotaču te nedostataka u modelu baterije, rezultati simulacije nisu u potpunosti zadovoljili. Zaključeno je da prikazani sustav ima perspektivu, ali je za konačnu potvrdu valjanosti nužno ponoviti testni ciklus uz poboljšanje sustava mjerenja mehaničkih veličina i poboljšanje modela baterije.

Abstract (english)

First part of master thesis presents energy components of electric vehicle system with detailed theoretical base. Further chapters offer Simulink electric vehicle model based on ZESA electric automobile accompanied by energy component calculation and minimization program assembly. Input value measurement acquisition process on ZESA vehicle is described. Torque at the wheel and linear vehicle velocity on the chosen driving cycle were used as an inputs. The same data was used for simulation verification, with expected energy component minimization in comparison with the original ZESA vehicle data. Because of the electromagnetic noise in torque and velocity measurements and imperfections of the battery model, simulation results could not be fully confirmed. In conclusion, presented system has a potential for further development, but for final verification, measurement process needs to be repeated and conducted on a higher level. Also, battery model has to be improved.
