Microprocesor controlled charger
Husník, Ondřej ; Ježek, Michal (referee) ; Kovář, Jan (advisor)
This thesis deals with design of microprocessor controlled battery charger with support of NiCd, NiMH and Li-Ion cells. The project focus is aimed within circuits design at algorithm of charge detection implemented into microprocessor. User interface is formed by PC application which communicates with charger via USB. PC connection allows recording of charging characteristics behaviour. The result of thesis is completely designed and created battery charger including microprocessor and PC application source codes.

Testing and charging of accumulator cells
Sršeň, Jan ; Kubánek, David (referee) ; Lattenberg, Ivo (advisor)
Direction of the master's thesis is design and construct electronic device for testing available accumulators. Than there are in detail subscribe some metods of charging cells and their right usage to select type of cells. Also eventually problems that can become if the choice is false. Next part contains description of principles as several type accumulator works and their loading characteristic witch are important know for choose the best testing way. The most important knowledge is detection of stop point charging when accumulators are charged and following charging can be dangerous. Because there are more methods to detect this point so in thesis are overwrite. The most important part is design of tester. That is mapped to more segments witch communicating together. Controller part of intelligent tester contains ATmega128 microcontroller so there is present a passage of program code. Last section of master's thesis describe a physical consruction and explain division for smaller parts and hole process of tester function.

Perspective bus powertrains
Kubík, Jan ; Maršálek, Ondřej (referee) ; Píštěk, Václav (advisor)
The aim of this thesis is to consider possible future development of alternative powertrains with regard to their use in buses. First described are the most promising alternative fuel vehicles, which use an internal combustion engine. The next part is evaluated ways to store energy using electric drives. At the end of the work is mentioned hybrid technology as a combination of previous drives.
