Abstract

U laboratoriju su obavljena eksperimentalna mjerenja odziva napona na pozitivnu i negativnu skokovitu pobudu struje, i to u više radnih točaka. Iz tih mjerenja optimiranjem je dobivena krivulja ovisnosti napona praznog hoda (Voc) o statusu napunjenosti baterije (SOC). Koristeći dobivenu krivulju, obavljeno je optimiranje parametara nadomjesne sheme baterije, u svim radnim točkama. Iz dobivenih parametara, određene su krivulje koje približno opisuju ponašanje svakog parametra ovisno o statusu... More napunjenosti. Sva optimiranja i proračuni su provedeni pomoću programskog paketa Matlab i grafičkog okruženja Simulink. Less

Abstract (english)

In the laboratory were made experimental measurements of voltage response to positive and negative step excitation of current, in few working points. From these measurements, by optimization was obtained curve that describes behaviour of open circuit voltage (Voc) in dependence of battery's state of charge (SOC). Using the resulting curve was made optimization of parameters from equivalent sheme, in all working points. From these parameters were determined curves that approximately describe... More the behaviour of each parameter in dependence of state of charge. All optimizations and calculations were carried out using software package Matlab and Simulink graphical environment. Less
