Electric drive for motorcycles
Černošek, Martin ; Kloss, Ondřej (referee) ; Kaplan, Zdeněk (advisor)
The diploma thesis is focused on rebuilding of the combustion engine powered motorcycle to the electromotor powered motorcycle. In the thesis is chosen the suitable electromotor, next is designed the accumulator system, then is created the construction design of location electric system in the motorcycle frame and at the end is made the strength analysis of the mechanical parts. For the construction design is created 3D model in SolidWorks. The diploma thesis is also focused on comparison the motorcycle powered by combustion engine and the motorcycle powered by electromotor in the Supermoto race.

Design and lay-out of high pressure pumping station.
Václavík, Tomáš ; Franc, Zdeněk (referee) ; Habán, Vladimír (advisor)
The aim of diploma thesis is design and lay-out of high pressure pumping station with plunger pumps for splash of scales from slabs of hot-rolled. Theoretic (introduction) part of this thesis contain description of formation of scales and description of ways how it is possible remove these scales. And this part contains also explication of effect of water jet on solid material. The practical part of diploma thesis is focused on design of pumping station including of dimensioning of machinery. Part of this work is also technical documentation for proposed pumping station and specification of main machines and devices.

Uninterruptible Power Supply with Solar Panel
Kreysa, Karel ; Dřínovský, Jiří (referee) ; Šebesta, Jiří (advisor)
This bachelor thesis is focused on a project and realization of uninterruptible power supply with the solar panel. The whole system will be instrumental towards supplying gauging radar station without any other possibility to get more electrical energy from the grid (230V). The most important argument for the project is the project is the effectiveness of sthe systems which should prevent losses in the network and unusing energy supplying by the panel. The aim of work is to create a scheme of a suitable leading storage battery type which will be used for saving energy made by the panel. Last but not least is to present the properties of storage battery to prevent wrong manipulating which could cause an effective life reduction or its total destruction. Then a circuit scheme of the back up system will follow. For this, a desk of printed circuits is going to be drawn up and set up. The final part of this thesis will concern a measuring of the whole system both in laboratory and real conditions and an analysis of the resulting parameters of the back up system.

Uninterruble Power Supply (UPS)
Junek, Michal ; Sekora, Jiří (referee) ; Chmelař, Milan (advisor)
This thesis is intent on quality and safety of electrical energy supply from distribution network. There are describe solutions to reduce or to remove the low quality phenomena of electrical energy supply. The thesis is mainly intent on uninterruptible power systems (UPS) as frequently using systems. There are desciribe systems normalization, topology, choosing and limiting disturbing factors. This thesis is intent on designing AC inverter.

Vanadium cells as a source and storage of energy
Langr, Pavel ; Chladil, Ladislav (referee) ; Novák, Vítězslav (advisor)
This semestral thesis deals with problematics of redox flow batteries, especially vanadium batteries. The first part is focused on describing basic terms, describes redox batteries and explains chemical processes. It also deals with vanadium batteries properties and construction. The second part of the thesis describes diagnostic method of spectroscopy, which seems to be very perspective for examining attributes of vanadium redax batteries.

The Autonomous House or Living Grid-off
Chlebný, Radek ; Šlezingr, Jan (referee) ; Macháček, Jan (advisor)
This thesis deals with energy self-sufficiency focusing on the independence of the electric grid. Basic line emanating project form a concrete proposal for autonomous energy supply system. Emphasis is placed primarily on photovoltaic systems, electric energy accumulation and selection of individual components of such a system. Another important part of the thesis is also an economic evaluation of design variations. The thesis also deals with a market research, and thereof derived benefit assessment of each technology. The accompanying chapters are then devoted to the history of autonomous life style or classification of buildings according to their energy performance.

Dynamic model of the batteries
Milichovský, Miloš ; Vaculík, Sebastian (referee) ; Tošer, Pavel (advisor)
The thesis includes the basic principles of lead-acid, NiCd, NiMH and Li-Ion batteries. There is a description of their features and phenomena that processes in the batteries during charging and discharging. The most important part is devoted to dynamic models of these types of batteries, the parameters that are necessary for their modeling, and testing of absolute error models. Further, the model in Matlab was created which allows the simulation of the GRID-OFF photovoltaic system using the battery model.

Smart accumulator tester and charger
Mílek, Čestmír ; Trmač, Jiří (referee) ; Michálek, Václav (advisor)
Nickel cadmium and nickel metal hydride accumulators sets are currently used for supplying hand tools (screwdrivers,...). Problems of cheap hand tools are chargers, mostly of it doesn’t use any charging driving circuits. In consequence of it the accumulators are kept incorrectly, which causes lowernig of lifetime. This thesis suggest circuit design Main of intelligent charging system, which enable better battery management, increases battery lifetime and lower load of environment.
