Abstract

U radu je razvijen model ekvivalentnog kruga drugog reda koji se koristi za određivanje napona i stanja napunjenosti baterije. Model je izrađen na temelju krivulja napona i struje dobivenih eksperimentalno u laboratoriju na stvarnoj bateriji. Parametri modela dobiveni su aproksimacijom dijela krivulje napona, a napon otvorenog kruga određen je također iz eksperimentalnog napona. Identifikacija modela, odnosno njegovih parametara je kvalitetno napravljena jer su se dobili rezultati koji se u većini situacija dobro poklapaju s eksperimentalnim rezultatima. Model je verificiran na temelju krivulja napona te usporedbom s eksperimentalnim krivuljama na stvarnoj bateriji.

Abstract (english)

This paper developed an equivalent circuit model of second order that is used to determine the voltage and state of charge of the battery. The model was created based on voltage and current curves obtained experimentally in the laboratory on a real battery. The model parameters were obtained by approximating parts of voltage curve and the open circuit voltage was also determined from the experimental voltage. The identification of the model i.e. its parameters was done well because the simulation results are good in most cases and match well with experimental results. The model has been verified by comparison with experimental curves on a real battery.
