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.

Influence of nanoparticles on the properties of electroinsulating materials
Sedláček, Michal ; Rozsívalová, Zdenka (referee) ; Frk, Martin (advisor)
This work deals with influence nanoparticles, as fillers of polymer, to electrical properties dielectric composite materials. Addition of just a few weight percent of nonofillers has profound impact on the physical, chemical, mechanical and electrical properties orf polymer. Simultaneously is focused on production and diagnostics by the relaxation spectroscopy and measure internal resistance. Examination material is epoxy resin TSA 220S filled Al2O3 and SiO2 nanoparticles.
