Electromobility, today and vision
Valíček, Roman ; Kracík, Petr (referee) ; Milčák, Pavel (advisor)
The main target of this bachelor thesis is to create an overview of current and future status of electromobility in the Czech Republic, including an analysis of possible impacts of this developing field to other sectors, especially energy industry and ecology. This work is divided into several sections. The first part is research and it deals with general knowledge related to electromobility at first and then it analyzes the current situation in our country. The electric vehicle charging and electromobility support are discussed in detail. The second part of the thesis focuses on the influence of electromobility growth on the power system and on the electromobile emission footprint. These chapters are based on self calculations and the results are evaluated at the end. The conclusion summarizes the findings and there is a comment about upcoming development of electromobility in the future.

Infrastructure for electromobility
Smutková, Karolína ; Böhm, Michael (referee) ; Štětina, Josef (advisor)
This thesis deals with the issue of charging electric vehicles, including a number of sub-questions. It provides an overview of current charging stations, connectors, communication between vehicle and charger during charging and of the resulting price for charging. It also takes into account the need for large amounts of energy mostly from renewable sources, coupled with battery storage facilities. The last point is a comparison of current electric vehicles mainly by battery capacity, price and range. The whole thesis is primarily related to the territory of the Czech Republic.

A study of electric vehicle recharging
Solař, Adam ; Kučera, Pavel (referee) ; Píštěk, Václav (advisor)
The subject of this thesis on the topic of the study of the electric vehicle charging. The aim was to draw up a research study on the history of the electric vehicles, the options of their charging and to assess the availability of the charging points in our country and abroad. Additionally, this study provides overview of the electric vehicles available on the market and the types of charging devices and charging options. In conclusion, a large number of the ways and charging types were discovered. Furthermore, we calculated the approximate charging time with regard to the type of charging device and convenience of the charging points. This work also mentions some disadvantages of the electric vehicles, such us the long charging time, charges for the fast charging station use or currently high retail prices of these cars. Despite the prevailing drawbacks, the electric cars are becoming more visible on the roads.

Infrastructure for electric buses
Adamec, Matěj ; Rekem, Jakub (referee) ; Štětina, Josef (advisor)
The aim of this bachelor thesis is to examine the charging infrastructure of electric buses from the point of view of dynamically charged buses, trolleybuses, statically charged battery electric buses and their combination in the form of partial buses. In the case of the trolleybus infrastructure, the method of powering the contact wire traction, the properties of the contact wire are described, and the operation of partial buses are not omitted. For the charging infrastructure of battery buses, a detailed evaluation of the methods of connection to the charging station, charging modes and an overview of offered charging solutions from selected companies is performed. Considerable attention is paid to the possibilities of standardization and automation of connections to charging stations. In the final chapter, an approximate calculation of the optimal capacity of the battery storage for the selected line and the subsequent evaluation of the charging solution of the operating electric buses on this line is performed.

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.

Electric vehicle charging solutions in apartment complexes
Machajdík, Marek ; Poulíček, Matěj (referee) ; Štětina, Josef (advisor)
In the work, public charging stations are classified, their description is given, and is added information about the compatibility of charging stations with current electric cars. Information of individual electric car charging using wallboxes is summarized and their characteristic features and power limits are listed. Considerable attention is paid to V2B technology and the possibilities of charging electric cars in multi-unit apartment buildings with their own parking space. The work will also include a file used to calculate a suitable solution for charging electric cars in an apartment building. The final part of the work is devoted to the solution of charging electric cars for a specific apartment building using the created calculation file.

Evaluation of possibility of modifying selected part of public lighting network for EV charging
Hýsek, David ; Vrána, Michal (referee) ; Baxant, Petr (advisor)
The master thesis deals with the concept of smart cities in the context of motivation for the use of the synergy of public lighting network and charging points. The thesis provides an overview of projects from the Czech Republic and abroad focusing on the adaptation of the urban public lighting network for charging electric vehicles. Different variants of charging station installations and their management are discussed. Another important topic is the selection of a suitable location for charging stations and the concept of synergistic connection of these stations with the existing public lighting network. The thesis proposes scenarios for using the existing public lighting network for charging electric vehicles and scenarios for bringing a parallel cable to this network in selected Brno locations. The aim is to optimize the efficiency and performance of the public lighting network and at the same time provide a charging infrastructure for electric vehicles. The results of the thesis represent a valuable contribution to urban planning and the development of smart cities that focus on sustainable and environmentally friendly mobility. The synergy between the public lighting network and charging points represents a potential for efficient use of infrastructure in the urban environment while contributing to the reduction of greenhouse gas emissions.
