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.

Energy data monitoring in electric vehicle
Krejz, Jan ; Dedek,, Jan (referee) ; Baxant, Petr (advisor)
The thesis deals with the monitoring of the energy data in an electric vehicle using modern diagnostics, using data readings from the CAN bus. The thesis can be divided into three parts. The first part provides a theoretical introduction to the measurement systems found in electric vehicles, then there are the methods of data transmission within the electric vehicle and the possibilities of how to obtain this data. The second part is an overview energy model that theoretically describes the possible flows of electrical energy within an electric vehicle, this theory is then supported by models in Simulink software for specific situations and tests where the theoretically calculated values of energy consumed were verified using this model. and the measured values. In the last section, a proposal for tests and locations where it would be appropriate to monitor these flows is presented. Some of the tests were performed and then evaluated.

Perspectives of hydrogen propulsion and electromobility
KLEIN, Jan
This thesis deals with the issue of hydrogen propulsion and electromobility. Initially, hydrogen as a chemical element is explained. Thereafter its production, transport and storage are described, the direct principle of hydrogen combustion is discussed and examples of cars using hydrogen are given. Then the subject turns to fuel cells, where the principle of its function is explained, several types of fuel cells are outlined, and the design of a fuel cell car is presented. Next, electricity and its infrastructure are highlighted, and the functional principles of electric vehicle components are explained. Then the functions and specifications of charging points are described. At the end of the theoretical part, different types of plugins for EV charging used globally are presented. In the practical part, an analysis of the number of hydrogen fuel cell cars and EVs worldwide, Europe and the Czech Republic was performed. Furthermore, the infrastructure of both types of cars was mapped on an identical scale and a survey was carried out in the district of Czech Budweis to map hydrogen filling stations and charging points for electric vehicles.

History of EVs and measuring battery under external force.
Šedina, M. ; Kazda, T.
This article describes the modern history of electromobility with the prediction of its market growth and the drivers of change. There are mentioned Li-ion battery's anode materials with their basic parameters and one of the conversion materials, silicon, which represent one of the possible materials for enhancing the capacity of the anode. Usage of the Si opens a few problems which are unnoticeable with actual anode materials, but there are some possible ways how to solve them. One of their solutions could be external force applied on the battery surface, which should reduce inflation of the battery and improve internal conduction.
