Tester for lithium cells
Buček, Vojtěch ; Tomíček, Pavel (referee) ; Dvorský, Adam (advisor)
The thesis deals with testing the state of lithium batteries, their aging, and verifying manufacturer-specified parameters. Based on commercial solutions for lithium battery testers, a custom circuit is designed and fabricated to verify the parameters of the measured batteries. The design includes necessary modules, components, and a description of the issues related to measuring lithium cells. The proposed tester allows for transferring measured data to a computer for subsequent processing and interpretation. Current necessary information is displayed in real-time on the screen. By comparing with a laboratory tester, the accuracy of the custom device is determined.

Cable harness tester
Vlasák, Stanislav ; Havránek, Zdeněk (referee) ; Burian, František (advisor)
This paper is focused on the problematics in testing of cables and wire harnesses. It follows up on a diploma thesis by Ing. Jakub Valenta. This paper consists of analysis of said diploma thesis and points out its shortcomings. Specifications of created protype of cable tester are mentioned in this paper, including its accuracy and suggestions for more accurate measurement of cable harnesses. Goal of this paper is to create a functional sample of cable tester based on foundations of Ing. Valenta

Industrial Tester for Photometric Values of LED diodes Used in Automotive Signal Lighting
Gaži, Dominik ; Froehling, Kenneth (referee) ; Baumgartnerová, Alena (advisor)
V posledních letech zažili světlomety v autech obrovský technický rozvoj, který se podílel na jejich současné složitosti. Aby řidiči i zákazníci byli spokojeni, je využíváno různých technologií pro neustálé dosahování účinnějších a bezpečnějších světelných zdrojů. Společnosti usilují o minimalizaci ztrát ve výrobě ve snaze šetřit životní prostředí a konat ekonomicky. Tato práce se zabývá výzkumem osvětlovací techniky a návrhem jednoduchého a efektivního zařízení pro testovaní chyb LED plošných obvodů ve světlometech, to vše za účelem minimalizace strat. Dalším cílem je výzkum možností konstrukce takového zařízení z technologického hlediska.

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.
