Smart charger with cell identification
Alechko, Ivan ; Harvánek, Michal (referee) ; Kubíček, Michal (advisor)
Cílem bakalářské práce je zvolit vhodnou metodu pro identifikaci jednotlivých akumulátorových článku a vybrat vhodný způsob jejich nabíjeni. Ze zvažovaných metod identifikace jsem vybral jako vhodnou technologii RFID. V práci je popsán princip identifikace včetně konkrétního návrhu pro následující realizaci funkčního zařízeni. Část práce je věnovaná problematice nabíjeni akumulátorů. V této části je detailně popsán charakter nabíjeni článku v závislosti na jeho chemickém složeni. Pro realizaci (demonstraci funkce) jsem zvolil technologii nikl-metal hydridových článků (Ni-MH). Důraz jsem kladl na bezpečné a zároveň efektivní nabíjeni. Dalším úkolem bylo navrhnout metodu dlouhodobého sledování stavu akumulátorů v průběhu více nabíjecích cyklů. K tomu bude sloužit mikrokontrolér, který bude pro každý článek zaznamenávat údaje o nabíjecím cyklu.
Smart charger with cell identification
Podaný, Matěj ; Povalač, Aleš (referee) ; Kubíček, Michal (advisor)
This thesis is looking for a suitable method of unambiguous identification of charging cells, so that it can monitor their capacity in the long term and eliminate defective cells. It proposes several such methods where only the most suitable one is selected for the subsequent demonstration. It describes the basic properties of rechargeable cells and selects the one that could be used to demonstrate the selected method of cell identification. It designs an intelligent battery charger which demonstrates the chosen method of identification on modified charging cells.
Influence of Mn ionts in nickel hydroxide on behavour electrodes
Cirkovský, Jaroslav ; Vrbický, Jiří (referee) ; Sedlaříková, Marie (advisor)
The aim of my diploma thesis was to explore the influence of manganese ions put into nickel nitrate structure. The attention was focused mainly on the stabilization of nickel nitrate a modification, which could not change into b modification. The theoretical part of my thesis focused on applied materials, kinds of acumulators, basic parameters of acumulators and the description of chosen methods of measurement employed. It contained the electrodeposition, the impedance spectroscopy and the cyclic voltammetry. The task of the experimental part was to measure the effect of manganese ions put into potassium hydroxide structure. Proportions of Ni (nickel nitrate) : Mn (manganese nitrate) 10:0, 7:3, 5:5, 6:1 and 6:4 were blended for the measurement. By means of the electrodeposition, there was a thin layer of nickel hydroxide with an admixture of manganese ions from nickel nitrate and manganese nitrate dilution put on the nickel plate. After the spread of the thin layer on the nickel plate, the measurement by the method of cyclic voltammetry followed. The next task consisted in trying to add KOH (potassium hydroxide) anionic and cationic surfactant into the dilution.
Secondary resources of electrical power for mobile robotics
Špaček, David ; Hrbáček, Jan (referee) ; Synek, Miloš (advisor)
The main aim of this BA thesis is comparison and unification of secondary resources used for mobile robotics. Especialy through their performace, durability, composition, weight and price. The work should be used for choosing of the proper power supply needed for working some mobile device, if there are known basic operating parameters.
