Wireless charging station
Navara, Albert ; Dvorský, Adam (referee) ; Šteffan, Pavel (advisor)
The topic of this thesis is the design and construction of a wireless charging station compatible with the Qi standard with the possibility of delivering higher power. A wireless receiver is also designed and constructed to evaluate the capabilities of the wireless charger. Before the design itself, the theory of transmission and procedures for selecting topologies and components are discussed in the thesis. In the design of the transmitter and the receiver, microcontrollers are used, which take care of communication with each other and set the required parameters. The assembled transmitter is tested with a receiver in the form of an LC circuit, with a purchased receiver, and with the designed receiver within various distances and deviations of the transmitter and the receiver. The final product is fitted into a plastic box printed on a 3D printer.

Proposal of measures in the low voltage network for the implementation of renewable sources and electromobility according to scenarios NAP SG
Vojtěch, Jan ; Kučera, Michal (referee) ; Ptáček, Michal (advisor)
The thesis analyzes legislative and strategic documents of the European Union and the Czech Republic which set targets in environment and energy area in 2030, alternatively in 2040. The individual chapter is dedicated to national action plans, where the most important is National Action Plan for Smart Grids setting specific requirements for future development of smart grids. The thesis contains analysis of distribution network in the municipality of Následovice and simplifying assumptions for the implementation of calculation. There are also introduced scenarios which have been used for the calculation of the distribution network with its results. Potential defects of the distribution network are commented with suggested solutions. The calculations were repeated to verify the solutions. Results are recapitulated in an individual chapter. Graphical outputs of the calculations can be found in the attachement.

Concept of Fast Charging Station with Accumulation for Electric Vehicles
Miškovský, Ján ; Morávek, Jan (referee) ; Mastný, Petr (advisor)
Main purpose of the thesis is the creation of a concept a fast-charging station associated with accumulation that uses renewable source. The introduction of the thesis describes a standard that specifies the charge of electric vehicles using direct and alternating current as well. It depicts an overview of using charging connectors. The first part also deals with overview of the technology of renewable sources and exploitation energy storage system for charging station. The second part introduces the theoretical basement for mathematical model of the charging station in Matlab/Simulink. The function of model station is verified by a physical laboratory model. For options verification of the connection station to the distribution net is created simulation of voltage losses in Matlab/Simulink. The thesis shows four 24 hours’ scenarios that have been simulated. According to the assumptions of simulation, the technology of station and connecting component is suggested. Next is the designed energy and financial analysis of the project charging station until 2030.

Design of Robotic Golf Ball Picker
Myška, Miroslav ; Bukvald, Jiří (referee) ; Sládek, Josef (advisor)
The main aim of this master's thesis is create golf ball picker with charging station. These two components create the system, which automates process of golf ball collection on driving range. The robot replaces human manual activity in this branch and it eliminates injury. On the other hand, robot respects functional, psychological, ecological and aesthetic demands. It demarcates standard principles of these days and new way how to collect balls on driving range.

Evaluation of current DS infrastructure to potential development of charging stations in the selected area
Hýsek, David ; Krátký,, Milan (referee) ; Paar, Martin (advisor)
The bachelor's thesis deals with the evaluation of the infrastructure of charging stations and the development of fast charging stations. The first part describes the basic charging modes and parameters of selected chargers. The second part of the work presents an overview of battery electric cars and slow and fast charging. Furthermore, the work concerns the electric car policy in Europe and especially in three selected countries: The Kingdom of Norway, the Federal Republic of Germany and the Czech Republic. In the last part of the work, three scenarios of electromobility development in the selected location in Brno were compiled and subsequently the load of these scenarios on the network in the Daisy Bizon designer program was verified.

Intergration of a charging station into a family house photovoltaic system
Liška, Martin ; Langerová, Petra (referee) ; Šedrlová, Magdalena (advisor)
This bachelor’s thesis deals with integrating a charging station into a family house photovoltaic system. The thesis is divided into two parts, the theoretical and the practical. The purpose of the theoretical part was to conduct research about current possibilities concerning charging stations and their integration into the household. In the practical part, there were created function designs to integrate the charging station into the intelligent household and there was realised the testing of the selected charging station.

Electric cars heating systems
Kolomazník, Milan ; Fišer, Jan (referee) ; Hejčík, Jiří (advisor)
The object of this bachelor thesis is a research concerned the electric vehicle interior heating ways. The basic terms connected with the electromobilism general problems are described at the beginning. The following part outlines the current problems that impede the wide expansion of these vehicles. The thesis sums up the direct methods of the heating using electricity and the alternative way, which is a self-sufficient heating using an internal combustion engine. It also assesses the applicability of heat loss emerging in the electric components, such as an electric motor, a frequency converter or an accumulator. Based on these findings, the various constructional drafts were created including a list of their strengths and weaknesses. The conclusion draws a comparison between each of these constructional solutions.

Charging Stations for Electric Vehicles
Zajac, Tomáš ; Ptáček, Michal (referee) ; Radil, Lukáš (advisor)
Bachelor´s thesis deals with issues of electric vehicle and EV charging. In its first part, categorization of EV´s is listed alongside with description of energy accumulation used in EVs and it´s key features. Furthermore, key mechanisms regarding EV charging standards and equipment are defined and the possibilities of varying charging station designs are presented and described. First part is closed by short overview of trends and innovations. Next part is focused on operating costs analysis of electric vehicles and vehicles with internal combustion engine. Final part deals with selection of charging station, creation and description of mathematical model of its charging cycle. Impact on grid is discussed along with optional partial decoupling of the load from the grid, achieved by the application of energy storage elements – buffer accumulation. Thesis is closed by proposal for calculation methodology for capital and operating costs analysis. This analysis is programmed and the overall cost of the investment is discussed.
