Fast charging of EV vehicles - overview of technologies
Boršoš, Adam ; Charvát, Pavel (referee) ; Fišer, Jan (advisor)
Charging speed is one of the key parameters that affects the attractiveness of electric cars for drivers. Therefore, it is important to determine the methods that can charge the electric car as quickly as possible. An overview of electric vehicle charging technologies and the identification of those that are considered fast charging has been made. It has been found that the fastest technology is DC charging. A list of six connectors that allow this charging has also been created. These were then compared. An overview of charging networks, that enable fast charging, was made in the next chapter. The three largest providers of charging stations in the Czech Republic and also the two that specialize in fast charging were listed. The topic of battery cooling is also related to charging. Therefore, the following chapter provides an overview of technologies that are used to cool batteries. The last part focuses on the factors that cause the degradation of batteries. An overview of the four main causes of degradation and their effect on the battery was demonstrated.

Fotovoltaics systems for block of flats
Krška, Lukáš ; Charvát, Pavel (referee) ; Hejčík, Jiří (advisor)
The aim of this work is identification with photovoltaic systems for a panel building and finding a solution how to apply it. The work deals with history of photovoltaics, focuses on natural conditions in the Czech Republic and a briefly describes particular components which photovoltaic system consists of. The panel building is divided into parts were is possible to use the system and further is in detail described the Evalon-Solar product which is optimal to use on flat roofs of panel buildings.

Ventilation of a cytostatic laboratory
Kicko, Peter ; Štětina, Josef (referee) ; Charvát, Pavel (advisor)
The main goal of this thesis is an introducing and guiding the reader with all important aspects of a proposal of ventilation system for cytostatics laboratory, from theoretical knowledge about the issue via familiarization with an appropriate legislative statute, a demonstration of relevant calculations needed for the project, a proposal in the form of technical reports as well. In this thesis the process of validation, which is needed for installed technology in the cleanroom, is also described. The thesis is supported by drawing documentation of real ventilation project for cytostatics laboratory, which follows the aforementioned technical report and calculations.

Proposal nozzle for measuring the air quantity of an internal combustion engine
Esterka, Ondřej ; Charvát, Pavel (referee) ; Štětina, Josef (advisor)
In this bachelor‘s thesis are mentioned emission standards, which apply to passenger cars, and the mixture-control system. There is also a research of volumetric and sectional flowmeters, suitable for measuring the flow volume of the air, including the principle of measuring the volumetric or mass flow. After that follows engineering design of Venturi tube for measuring the flow of the air through the chosen combustion engine. The design is based on the appropriate standard. There is also involved a welded assembly drawing of the Venturi tube, and a description, how to use the tube in a test room.

Mercury emissions in energy industry
Hlavinková, Valérie ; Klimeš, Lubomír (referee) ; Charvát, Pavel (advisor)
This bachelor thesis deals with mercury emissions in the energy industry. The main sources are described and the combustion behavior of mercury is characterized. Legislative measures limit mercury emissions, which pollute the environment and endanger human health. The application method makes it possible to reduce these emissions.

Design of a space and DHW heating system for a detached dwelling
Záboj, Jakub ; Pech, Ondřej (referee) ; Charvát, Pavel (advisor)
The thesis aims to propose a system for heating and hot water for a family house, according to drawings supplied by the building architect. At the request of the investor as the primary object will be considered a variant of underfloor heating. For comparing the heat loss, economic and possibly to State subsidies system selected will be processed by an alternative option to the ventilation air heating. Underfloor heating and hot air are among the low-temperature heating system, which can use low temperature heat sources, such as heat pumps. This assumption corresponds to investor requests, the source of heat in a family house with a heat pump and gas boiler. For hot water will be used as an alternative to a fireplace in the living room. To use the results of the thesis is to calculate the heat loss and heat, according to current standards include design and hot-water heating system including hot-drawing documentation. Finally, the economic evaluation of different alternatives in terms of investment and operating costs.
