Abstract

Definirana je potreba za upotrebom superkondenzatora i superkondenzatorskog sloga. Uz to, definiran je problem javljanja prenapona na pojedinim ćelijama u superkondenzatorskom slogu, koji može uzrokovati uništenje ćelije, a u nekim slučajevima i cijeloga sloga. Razmotrena je podjela sklopovlja koji rješavaju definirani problem tako da se višak energije na jednoj ćeliji u slogu prenese na drugu ćeliju. Opisane su dvije vrste sklopovlja za rješavanje definiranog problema: pasivno i aktivno sklopovlje za upravljanje energijom. Dan je opis metode upravljanja energijom pomoću dodatne ćelije superkondenzatora te je u Matlabu i Simulinku razrađen algoritam za navedenu metodu zasnovan na eksponencijalnoj funkciji prespajanja.

Abstract (english)

This work deals with the problem of overvoltage on particular cells in supercapacitor stack during charging and discharging processes, which can lead to cell destruction, and in some cases destruction of whole stack. The overview of assemblies that solve defined problem in way that extra energy from one cell in stack is transferred to another, was presented. The cell management systems based on passive and active approach are described. Cell management system based on balance cell was elaborated in detail. Control algorithm for cell management system based on exponential switching function is developed and tested by simulation using Matlab and Simulink.
