20.500.12556/DKUM-16430 METODE DOLOČANJA STANJA NAPOLNJENOSTI BATERIJ METHODS FOR DETERMINING THE STATE OF CHARGE OF BATTERIES Uvodoma so predstavljene polnilne baterije s poudarkom na litij-ionski LiFePO4 bateriji in najbolj pogoste metode določanja stanja napolnjenosti baterij. Prikazana in izdelana je eksperimentalna shema za določanje karakteristik baterij pri različnih pogojih delovanja. Izdelano je bilo eksperimentalno polnilno-praznilno vezje in eksperimentalna mini temperaturna komora za simuliranje obratovanja baterije pri različnih temperaturah. Prikazani so tudi rezultati meritev s programom LabVIEW, iz katerih je mogoče določati napolnjenost baterij in uspešnost delovanja algoritma. V teoretičnem delu ekonomskega dela diplomskega dela smo se na kratko posvetili tematiki vedenja in zadovoljstva odjemalcev. V empiričnem delu je bila s pomočjo spletne ankete izvedena raziskava vedenja in zadovoljstva odjemalcev baterijsko napajanih naprav, katero smo zaključili z analizo dobljenih rezultatov. First of all rechargeable batteries are presented with a focus on lithium-ion LiFePO4 battery and most common method of determining the state of charge of batteries. An experimental scheme to determine the characteristics of the batteries in various operating conditions has been demonstrated and produced. Experimental charge/discharge circuit and experimental mini temperature chamber for simulating the operation of the battery at different temperatures were made. Also shown are the results of measurements with LabVIEW program, from which it is possible to determine the battery charge level and efficiency of the algorithm. In the theoretical part of the economic part of the thesis, we briefly discussed the behaviour and customer satisfaction. In the empirical part we conducted an online survey on customer behaviour and their satisfaction with battery powered devices, which was concluded with an analysis of the results. : določanje stanja napolnjenosti baterij litij-ionska LiFePO4 baterija galvanostatsko prekinitvena titracijska tehnika napetost odprtih sponk gonilnik LabVIEW vedenje odjemalcev raziskovanje vedenja odjemalcev zadovoljstvo odjemalcev pričakovanja odjemalcev merjenje zadovoljstva uporaba in opustitev izdelka. state of charge determination Li-ion LiFePO4 Battery Galvanostatic Intermittent Titration Technique open circuit voltage LabVIEW driver customer behavior research of customer behavior customer satisfaction expectations of customers measurement of customer satisfaction use and abandonment of the product. true true false [S.
