Determination of active emissions of electric cars
Kaštánek, Petr ; Bayer, Robert (referee) ; Jaššo, Kamil (advisor)
This diploma thesis deals with the ecology of vehicles with combustion engines and electric motors, both in terms of operation and in terms of production of fuel or electricity. A closer focus is on active and passive emissions of cars with combustion and electric engines. Emission sources, their reduction options and measurement methods for their determination in the production of WLTP and NEDC cars are discussed. Non-exhaust emissions are discussed in detail. Furthermore, a measuring device based on the Arduino microcontroller is designed. This device is then used to measure solid particles from tires and brakes when operating vehicles with internal combustion engines and electric motors.

Zhodnocení současného stavu rozvoje elektromobility osobních vozidel
Tesař, Marek
The present bachelor thesis focuses on electric vehicles, which are increasingly used as a mode of ground transportation. In the first part of the thesis, the data on the growth of the number of registrations of electric vehicles in the Czech Republic, Europe and the world is pointed out. Furthermore, issues about the used method of propulsion, charging method, battery production are presented and expert research in the field of recycling is followed. The contribution of this work is a comprehensive overview of electromobility today, which is still in its early stages and its biggest weakness is batteries. Elec-tricity from renewable sources is also needed for a sustainable model.

Současný stav a budoucí přínosy a rizika elektromobility v České republice
Minaříková, Martina
This bachelor's thesis deals with the analysis of the current state of electromobili-ty in the Czech Republic and the evaluation of the benefits and risks related to it. The literature review summarizes the history of electromobility in the world and in the Czech Republic up to the 21st century and the basic types of electric vehicles. Furthermore, the current state of the infrastructure of charging stations, the number of electric cars and the benefits offered by the state is evaluated. Finally, the ecological, technical, economic, and social benefits and risks of electromobility in the Czech Republic are assessed here. The analytical part of the bachelor's thesis is carried out using a questionnaire survey. The questionnaire includes questions regarding the respondents' perception of electromobility, their assessment of the advantages and disadvantages of electric vehicles, and specific questions focused on the respondent's general knowledge and orientation in this issue. Based on these data, an evaluation of the individual answers is carried out, followed by an evaluation of the established research questions. Finally, a profile of the potential owner of the electric car is created. The summary of the results of the questionnaire survey allows to get an overview of the opinions and preferences of the respondents, which can be a key factor for the introduction of electromobility in the Czech Republic.

Ekonomické a ekologické aspekty elektromobility
Otáhalová, Barbora
The bachelor thesis deals with the dependencies of economic and ecological factors in the field of electromobility in European countries for the year 2021. The literature review characterizes electromobility, briefly describes its development, current status, as well as advantages and disadvantages. Furthermore, a comparison of certain factors between European countries is presented in this chapter. The theory of regression analysis and the stages of econometric modelling are also included in this study. The practical part includes creating and testing two econometric models. The results show that there is a positive dependence between GDP, the number of charging stations and the number of newly registered electromo-biles. Another sub-result is the confirmed dependence of newly registered EVs on the reduction of CO2 emissions.

Solární dobíjecí stanice a možnosti jejich využití v ČR
Deml, Jan
DEML, J. Solar charging stations and possibilities of their use in the Czech Republic. Bachelor thesis. Brno: Mendel University in Brno, 2023. The further development of electromobility and the growth of the number of electric cars is connected with the demand for charging stations, both public and domestic. It is therefore necessary to deal with the issues of their construction with the maximum use of ecological energy sources, including solar. In the research part of the thesis, it summarizes knowledge about solar charging stations and the possibilities of their use in the Czech Republic. Furthermore, using examples of good practice, a study of the opportunity for the construction of a public solar charging station is prepared, using which the key factors for the construction of solar charging stations and the possibilities of their support in the Czech Republic are defined.

Electromobility and Power Engineering
Pospíšil, David ; Milčák, Pavel (referee) ; Lisý, Martin (advisor)
This bachelor thesis focuses on electromobility in the Czech Republic and analyses its impacts on the power grid, electro-energetics and the charging possibilities of electric vehicles. The introductory section describes different ways of charging electric vehicles and forecasts future demand for charging stations. Subsequently, the impacts of electromobility on the power grid and electro-energetics were examined, which showed an increased load due to electromobility and need for modification of the infrastructure. At the end of each chapter, the results were summarized and possible solutions were proposed of the problems arising from the development of electromobility.

Analysis of powertrain systems of drilling equipment
Klíč, Zdeněk ; Pokorný, Přemysl (referee) ; Mergl, Václav (advisor)
This bachelor's thesis deals with powertrain systems of drilling rigs intended for construction work. The powertrain systems are divided according to the energy they used and then analyzed. This analysis includes a description of the important components in the systems, schematic images indicating the principle, a description of operations, power transfer, and specific examples of machines using each of the systems. The next part focuses on a summary of the pros and cons. The knowledge gained relates to modern drilling rigs with an emphasis on environmental friendliness. The result of the work is the generalization of this issue and the disclosure of a more detailed solution for individual systems.

Design of Multi-purpose Electric Scooter
Dvořák, Jan ; Paliatka, Peter (referee) ; Křenek, Ladislav (advisor)
The popularity of micromobility is rising. This not only contributes to a cleaner and quieter environment, but also helps reduce heavy traffic. This thesis is about the design of an electric scooter that has elements of an off-road motorcycle. This combines practicality with function, which push the level of micromobility further. Improves off-road ability while keeping comfort. The project was created in cooperation with the company KOSTKA – kolobka, s.r.o.
