Automatic System for Load Characteristics of Power Supplies Measurement
Vojtek, Michal ; Dřínovský, Jiří (referee) ; Šebesta, Jiří (advisor)
The target of this work is create device, which will automatic measure values for find out loading characteristics of power supply with help of built-in electronic load. In case, that source of current supply will for example DC/DC convertor, measurement of input current and input voltage will be possible. Then there is no problem with determinate total efficiency of this power supply. Measuring system will be conected via serial interface of type USB with computer. It will be possible to save found out values with help of control program for nother processing. Control unit of whole system will be suitable microcontroller.

Study of life cycle of the accumulators
Babieska, Lukáš ; Binar, Tomáš (referee) ; Kazda, Tomáš (advisor)
This bachelor work deals with monitoring the life cycle of a lithium-ion battery. The theoretical part describes the history and development of electrochemical cells. Lithium-ion batteries are a separate chapter. There are described their principles, the most used materials for the production of negative and positive electrodes, loading characteristics and the influence of temperature. In the practical part, the influence of temperature on changes of internal impedance, cell capacity and efficiency of energy supply during the battery life cycle is monitored.

Study Of Life Cycle Of The Accumulators
Babieska, Lukáš
This article presents the issue of changing the parameters of a Li-Ion accumulator during its life cycle. The introduction briefly describes the theory of accumulator charging and discharging and the effect of temperature on these processes. The next part introduces practical measurements and changes of parameters of two different accumulators.
