Abstract

U ovom zavržnom radu bilo je potrebno upoznati se s karakteristikama LiFeMnPO4 baterija. To je učinjeno na način da se baterija, sastavljena od četiri ćelije, punila i praznila konstantom strujom od 20, 30 , 40 i 90 A. Mjerenja su se izvodila pomoću akvizicijske kartice, a podaci su se pratili i zapisivali na računalu pomoću programa u LavVIEW-u. Konačne karakteristike su dobivene pomoću Matlaba.
Poslije je bilo potrebno steći uvid u postojeće sustave punjenja i balansiranja navedenih baterija. Dan je pregled prednosti i nedostataka nekoliko postojećih sustava i metoda za punjenje i balansiranje. Predložen je modificirani sustav koji uključuje i balansiranje i punjenje baterija te je razrađen na razini ideje.

Abstract (english)

Firstly, it was necessary to get to know characteristics of LiFeMnPO4 batteries in this final thesis. That was realized by charging and discharging the battery, made up of four cells, with constant current of 20, 30, 40 and 90 A. Measurments were done by data acquisition card, and they were being monitored and logged by LabVIEW program. Finally, characteristics were obtained in Matlab.
Later, it was necessary to get to know existing charging and cell balancing systems for given batteries. Overview of advandages and disadvantages of several charging and cell balancing systems and methods are given. Modified system was proposed which includes both charging and cell balancing. It was elaborated only on level of idea.
