Trolley for Acupack Charging
Silvester, Róbert ; Šebela, Kamil (referee) ; Janoušek, Michal (advisor)
Bachelor’s thesis devours around the construction and realisation of a small trolley, which purpose is transportation and charging of lithium battery for the team TU Brno racing. In the beginning of this thesis, we take a look at guidelines which contain criteria for the trolley’s design. Then we look at the previous solutions of the trolley. Next is description of elaborated concepts of trolley. Consequently, there is a description of making the final design of trolley taken from the perspective of individual sections. The last phase is about the assuring calculations of the critical parts of trolley.
Design of Electric Urban Vehicle Drive System
Pitoňák, Adam ; Míša, Jiří (referee) ; Hejtmánek, Petr (advisor)
This diploma thesis sets itself into the task of presenting a conceptual design of a powertrain system intended for a small electric vehicle of the L6e category. As a part of this thesis, in the initial part of this work, a survey of components and their optimal arrangement in the powertrain system of a small electric vehicle was carried out. Subsequently, after the presentation of the possible components of the powertrain system, testing of these variants was carried out, both form a mechanical and an electrical point of view, to guarantee the compatibility of the individual parts of the vehicle´s powertrain system. After the evaluation, the optimal variant of the drive system, intended for the concept on a small electric vehicle “Nanos” was selected. To determine the acceleration characteristics and the range of a vehicle equipped with such designed powertrain system, series of acceleration tests as well as vehicle range test according to the first part of the official WMTP cycle, intended for vehicles belonging to the category L6e, were performed. The resulting values of the vehicle´s acceleration and range tests are subsequently compared with the values of already existing vehicles belonging to the same category, thus enabling an overall evaluation of the powertrain system concept.
Solar irrigation design for a tropical greenhouse
Straňák, Rastislav ; Vaněk, Jiří (referee) ; Jandová, Kristýna (advisor)
The aim of this master’s thesis is to create a solar irrigation system for a tropical greenhouse under the organization Lužánky – středisko volného času. The work initially focuses on examining the current state of the greenhouse as well as various possibilities for its automation in relation to generating electricity from renewable sources. The proposed device, consisting of an integrated circuit board, is powered by a solar panel and includes external peripherals such as artificial lighting and mist irrigation. The thesis also includes testing the functionality of individual electrical circuits, the complete device in the greenhouse, as well as its impact on climatic conditions.
Vehicle Hydropneumatic Unit
Koudelka, Roman ; Hejtmánek, Petr (referee) ; Blaťák, Ondřej (advisor)
This diploma thesis, following the bachelor's thesis, is devoted to the gas-liquid unit of a vehicle, as the central element of hydropneumatic suspension. The aim is to dimension and construct this component and integrate it together with other elements into a complex suspension system. Based on possible forms listed in the research section, regarding to current development trends, the form of the unit is chosen. The practical part begins with simulations comparing a hydropneumatic with a conventional suspension system. After solving this issue, it is possible to proceed to the dimensioning of the basic parameters of the unit and then to its construction, respecting the relevant strength calculations. The last step is to build a conceptual design of the whole hydropneumatic suspension system.
Lighthouse for maritime communication
Chadima, Jan ; Mašek, Pavel (referee) ; Pospíšil, Jan (advisor)
This bachelor thesis deals with design and construction of lighthouse model, which will be used for teachning. It describes types of naval signalizacion, which are established by organization IALE in decree E-110. In thesis is described Arduino platform, metods of 3D printing and used materials For model needs was designed printed circuit board with microcontroller ATmega328P, which control RGB LED. Program, which control model, was writed on Arduino platform. Program has nine modes of sea light comunication. It can change periode, color of LED, brightness and turning on power saving mode. The result of this work is a functional model of lighthouse powerd by battery. Model is based on Green Cape Lighthouse in Australia in scale 1:58.
Study of the properties of the advanced cathode materials for lithium-ion cells
Tichý, Jiří ; Vondrák, Jiří (referee) ; Baumgartnerová, Alena (referee) ; Kazda, Tomáš (advisor)
Tato práce se zabývá studiem akumulátorů, zejména lithium-iontových, principy jejich funkce a zejména studiem katodových materiálů pro lithium-iontové akumulátory. Tyto materiály by měly umožnit vývoj akumulátorů se značně vyšším jmenovitým napětím. Cílem práce je seznámení se s problematikou a shrnutí dosavadního vývoje na poli vysokonapěťových lithiových akumulátorů.

Stránský, Patrik ; Šimek, Milan (referee) ; Slavíček, Karel (advisor)
Goal of this bachelor thesis is to design the power supply for low-consumption electronic devices based on Lithium-polymer battery, which will be charged by photovoltaic cells. The main task is construction of Li-Pol battery charger which will respect fluctuating voltage supplied by solar cell.
Electrocar traction drive supplied with the hydrogen fuel cell
Pokálený, Jan ; Huták, Petr (referee) ; Patočka, Miroslav (advisor)
The topic of this diploma thesis is a traction drive of electrocar with fuel cell. The drive is supplied with hydrogen fuel cell with power of 2 kW. The traction drive consists of the three-phase DC/AC converter and the asynchronous machine. The main part of this work is a creation of the mathematical model of the traction drive in program Matlab–Simulink.
Study of the degradation of Li-ion batteries using electrochemical and other nondestructive methods
Gavalierová, Veronika ; Binar, Tomáš (referee) ; Kazda, Tomáš (advisor)
This bachelor thesis is focused on the study of the degradation of Li-ion cells, using non-destructive methods. The theoretical part contains the basic issues of the technology, basic concepts and knowledge. Next, we move on to the practical part, where we verify the described methods in practice.
Design of a photovoltaic power plant for a family house near Jihlava
Dvořák, Vít ; Maule, Petr (referee) ; Vaněk, Jiří (advisor)
This diploma thesis deals with the design of a photovoltaic solar power station for a specific family house in the Jihlava region. The aim of the work was to get acquainted with technologies about the production of solar systems, evaluate the market in the Czech Republic and create a design of photovoltaic solar power station. Three designs of power stations were created with the help of the PV * SOL design system. Each design uses different photovoltaic cell technology. The result of each power station design is a complete finished project, which is based on many factors such as the efficiency of the entire system in a certain location, financial analysis, return on investment and more. In addition, these projects meet the conditions for the preparation of the subsidy program Nová zelená úsporám. At the end of the work, all three designed power stations are evaluated and with the help of multicriteria analysis, the best and most advantageous power station design for the given locality is determined. In the end, the idea of further development of the project is presented.
