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.

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.

Concept of Charging Stations with off-grid Operation for Electric Bicycles
Leitman, Valentín ; Morávek, Jan (referee) ; Mastný, Petr (advisor)
This thesis deals with charging stations for electric bicycles powered by renewable energy. The aim of this work is to make a proposal for the hybrid charging stations for electric bicycles, which will work independently and, if necessary, will be backed up by a network. In this thesis is entered theoretical information on the issue of electric bicycles, the batteries, charging stations, the connectors of chargers, and photovoltaic systems. The practical part of this thesis is the basic design of the charging station and its design of the mathematical model of the individual parts in Simulink program, which are linked to the actual design of the charging station. In conclusion, this thesis deals with energy and economic analysis of the proposed system, therein included various methods of assessing investment recommendations of appropriate processing methods and overall assessment of the subject.
