Analysis of Smart Grid devices
Kolacia, Tomáš ; Šlezingr, Jan (referee) ; Radil, Lukáš (advisor)
This work deals with smart grids and smart metering in power grids. The first part of the thesis is focused on the comparison between classic topology of electrical grid and smart grid concept including the benefits, which could be achieved. The other parts of smart grid concept are described as well, such as energy storage and electromobility including charging points infrastructure. The second part of the thesis deals with smart metering devices and it describes routing protocols for smart grids. The following chapters summarize practical experience with addressed issues in Europe and in the Czech Republic. The last part is dedicated to evaluation of smart metering implementation in the Czech Republic.

Prospects for electric individual transport
Skoupý, Martin ; Strecker, Zbyněk (referee) ; Mazůrek, Ivan (advisor)
The aim of the thesis was to create a complex summary of the possibilities of the use of electric vehicles in individual transport, identification of the problems connected with the implementation of electromobility and listing the possibilities of their solutions. The thesis therefore dealt with the benefits in terms of emissions production, with the capacity of infrastructure or the trends in transportation. The need of the changes in the system of transportation was concluded based on the gathered information, i.a. greater use of lighter vehicles or shared transport. At the same time, more measures will need to be taken in the field of electricity production, which is still largely dependent on fossil fuels.

The use of soft computing as support for business decision-making
Pekárek, Jan ; Jašek, Roman (referee) ; Lenort, Radim (referee) ; Zinecker, Marek (referee) ; Dostál, Petr (advisor)
The presented dissertation deals with the problem of deploying the charging infrastructure for electric vehicles in the Czech Republic. The core of the thesis is a mathematical optimization model, which is implemented in the language of MATLAB computing software. The model consists of several sub-units representing separate models of studied sub-problems. The individual chapters of the work describe successively these sub models. The sub models are: demand model of the charging service, model of charging supply, charging simulator model, optimization model and its resolving optimization method. The optimization model is accelerated by parallelization on the graphics card. The optimization method is designed as a case-specific implementation of genetic algorithms on a population of tree-structured individuals. The final chapter deals with an economic aspect of the problem under consideration, the implications of the findings and the role that the optimization model plays in the context under consideration. The main benefit of the work lies in the formulation of the problem as a mathematical model, the accompanying analyses and the provided justifications. Any user with updated data can then use this work along with the attached scripts to find answers to questions about the relationship between electromobility and the charging infrastructure.

Impact of massive electromobility on the Czech Republic
Řeha, David ; Vančura, Jan (referee) ; Hejtmánek, Petr (advisor)
This bachelor thesis deals with the impact of the massive development of electromobility in the Czech Republic. Its importance is compounded by the fact that there are more and more speculations about the sustainability of our planet's development. This document describes the current state of electromobility, the state's position on this issue and the prediction of the number of these vehicles. It also analyzes the impact of a gradual increase of electric cars and the impact of using only electric vehicles, in terms of energy, where a large increase in electricity production and consumption is expected, ecological, where emissions are expected to decrease, and economic, where an increase of investment is expected and a decrease in state budget revenues.

Power Systems Ranges of Main Parameters
Řehořek, Tomáš ; Gála, Michal (referee) ; Paar, Martin (advisor)
The thesis deals with description of the power system, parameters of it’s components and the range of outputs and consumption. In the first part the structure of the power system is described as well as the fundamental division of electric grids. In this part the work also touches on the ways of supllying the elctric traction. Furthermore the amount of production and consumption is mentioned. In the second part this work focuses on description of selected components of the power system and their real parameters. Furthermore the work also touches on the matter of electromobility and battery energy storage systems. In the last part of this work a few simple methods of consumption estimation are presented. This work also includes two infografics, that describe the power system.

Battery pack for an electric car
List, Jaroslav ; Kalivoda, Milan (referee) ; Polzer, Aleš (advisor)
Thesis deals with the design of a battery box with lithium-ion technology, for the largest possible driving range of the BUT SuperEL II electric car. Based on the analysis of the electric vehicle available space and the parameters of the electronic system, the maximum size of the entire set of 84s130p batteries was designed. 18650 cells with NMC technology were selected due to the very high gravimetric and volumetric density, which reaches 274 Wh/kg and 564 kWh/m3. The total nominal capacity of the designed battery boxes in the electric car is 138 kWh. The total gravimetric energy density of the designed box is 215.6 Wh/kg. It allows the electric car to reach the theoretical range with a consumption of 14 kWh/100 km of almost 1000 km. The individual battery modules of the battery box are controlled for optimal operating conditions by means of a BMS. The whole set is divided into 5 battery boxes. These boxes are manufactured using the technology of bent welded sheets from aluminum alloy EN AW 1050A and steel 1.4301. FEM analyzes were performed to verify the mechanical strength of the designed structure. The work also deals with the design of battery modules and their connection.

MEB modular platform for electric cars
Tkach, Svitlana ; Kaplan, Zdeněk (referee) ; Píštěk, Václav (advisor)
This bachelor’s thesis focuses on the possibilities of the newly developed modular electric drive matrix MEB of the Volkswagen Group. The aim was to create a research study about technical parameters of the platform and the possibilities of its use for various categories of vehicles not only within the Volkswagen Group, but also the offer to competing manufacturers. In conclusion of the bachelor’s thesis is formulated the impact of technologies, offered by the modular electric drive matrix, on the development and production of electric vehicles and the related possibility of a reversal in the expansion of electric drive.

Determination of active emissions of electric cars
Kaštánek, Petr ; Bayer, Robert (referee) ; Jaššo, Kamil (advisor)
This diploma thesis deals with the ecology of vehicles with combustion engines and electric motors, both in terms of operation and in terms of production of fuel or electricity. A closer focus is on active and passive emissions of cars with combustion and electric engines. Emission sources, their reduction options and measurement methods for their determination in the production of WLTP and NEDC cars are discussed. Non-exhaust emissions are discussed in detail. Furthermore, a measuring device based on the Arduino microcontroller is designed. This device is then used to measure solid particles from tires and brakes when operating vehicles with internal combustion engines and electric motors.
