Concept of electromobile
Melounek, Michal ; Beran, Martin (referee) ; Porteš, Petr (advisor)
The object of the bachelor thesis is to create a research in field of electromobile. The project outset is devoted to the main ideas and to the history of the electromobilism. The second part describes electric system and used conceptions of the electric motor placing. The following part describes the sources of energy and the ways to recharge. The end includes some electro mobiles that are going to be a stock car.
Systems energy recovery for personal and sports vehicles
Marada, Ondřej ; Zháňal, Lubor (referee) ; Beran, Martin (advisor)
This bachelor thesis is dealing with methods to decrease energetic and ecological load of cars. In particular, it follows kinetic energy recovery systems (KERS). The thesis summarizes the types of KERS, their building elements, i. e. the establishment for accumulation of energy and its transmission. Then the survey of known fulfilments KERS follows and in the conclusion it is dealing with their contribution to the use of sport and personal motor cars.
Accumulation of energy
Neuman, Tomáš ; Kloss, Ondřej (referee) ; Kaplan, Zdeněk (advisor)
This bachelor thesis comprises a technical retrieval of overview of energy accumulation usable in cars. The basic characteristics and problems of particular kinds of accumulators and ways of accumulation are brought in this thesis, describing characteristics of lead accumulator, the structure and composition of electromobiles and appropriate batteries. In the following part the description of heat and hydrogen accumulator is stated. The end of this bachelor thesis is dedicated to mechanical accumulator.
High-lift truck-types of drive
Kučera, Jonáš ; Škopán, Miroslav (referee) ; Špička, Jiří (advisor)
This bachelor thesis deals with drives of High– lift trucks, types of drives and basic description. It also includes confrontation of some parameters of single drives.
Konstrukce elektrického motocyklu
Dobeš, Jan
In diploma thesis Construction of electric motorcycles I deal with issue of electric motorcycles, their types, constructions, advantages and their use. One part includes description of tractions and transmissions. Next part describes batteries, which are necessary in electric vehicles. The aim of this work is to compare different solutions of vehicle constructions. Experiment is about two constructions of quad. This quad used combustion engine and was modified to electric power. Electric quad was tested on power testing stand. Experimental quad constructions which were used were compared and evaluated. Experiment included test of stamina of fully charged battery.
Solar charge controllers for off-grid systems
KRČKA, Pavel
This diploma thesis deals with photovoltaic rechargable regulators used in isolated, or off-grid photovoltaic systems. First, basic types of off-grid installations, including their functions and applications in practice are described. Then, possibilities of electric energy accumulation in photovoltaic systems are mentioned, considering actual, accesible technologies. Matters of electric energy accumulation in leaden accumulators are examined in detail. Main part of the diploma thesis is about electronic designs of photovoltaic, also called solar, rechargable regulators. These are the main connecting part between photovoltaic panels, accumulator, but also often connected charge, which is appliance. Individual electronic regulators concepts are described narrowly, then compared and evaluated in thesis´ conclusion.

Minimalizace vlivu výrobků na životní prostředí
ETC Consulting Group, s.r.o., Praha ; Durdil, Josef
Cílem projektu je určení klíčových faktorů minimalizace vlivu vybraných výrobků na životní prostředí během jejich životního cyklu, posouzení životního cyklu vybraných výrobků z hlediska vlivu na životní prostředí. Jako předmět řešení byly definovány pneumatiky, galvanické články, baterie a elektrické akumulátory, výbojky a zářivky, chladničky používané v domácnostech, minerální oleje. V roce 2004 byly shromážděny základní informace k řešení projektu, informace o způsobu výroby, užívání i skončení životnosti výrobku (fáze, kdy se výrobek stává odpadem). Nejpodrobnější informace byly získány ke komoditě pneumatiky. Dále byly získány podklady pro galvanické články, baterie a elektrické akumulátory. Byl zpracován návrh metodiky ECO designu.
