Development of a GPS tracking device for the specific needs of a tourist club
Němečková, Karolína ; Věchet, Stanislav (referee) ; Appel, Martin (advisor)
This Bachelor thesis focuses on the development of a GPS tracking device for specific needs of tourist club. First part summarizes available products on the market and technologies which can be used for creating such a device. The second part describes the concept, which outlines the exact function of the transmitter and receiver. It follows by describing selected electronics, printed circuit board design, program implementation and the manufacturing of enclosures. To demonstrate the functionality, tests of wireless communication, discharge characteristics and device consumption are performed.

Micromobility and their charging
Papež, Michal ; Bárta, Jan (referee) ; Paar, Martin (advisor)
The bachelor´s thesis deals with electric micromobility and developing of the charging infrastructure for electric micromobiles. It also deals with electromobility and charging of electric cars. In the thesis are presented types of electric micromobiles and their battery capacity. The possibilities of using micromobiles are presented, including the concept of shared micromobility and legislative news related to micromobility. In the thesis are presented development possibilities and important aspects for the development of charging infrastructure for micromobiles. In the city of Brno were selected locations which are relevant for building new charging points. Part of the thesis is devoted to the charging of electric cars for comparison with the micromobility, the part submits the state of the charging infrastructure for electric cars and presents list of problems caused by charging of electric cars.

Docking Station for Automatic Charging of Batteries of Robot
Beran, Jan ; Janoušek, Vladimír (referee) ; Rozman, Jaroslav (advisor)
The aim of this thesis is to create a functional docking and charging system for the Trilobot robot, which is improved and modified for use in future projects as a part of this thesis. The theoretical part discusses the path planning methods, battery types and charging methods, types of docking stations and the charging method itself. Also, a robot refurbishment design is presented, which is then implemented, along with the docking station. The refurbished robot has functional control software in the ROS framework, which allows it to perform not only the task of autonomous battery charging. In this thesis, a test of the whole system is also performed and the results are evaluated.

Supercharging of internal combustion engines
Vrána, Jan ; Jedelský, Jan (referee) ; Štětina, Josef (advisor)
In supercharging are applied mainly two ways - turbocharging or charging using a mechanical compressor. The aim of thesis was to compare the ideal cycles of internal combustion engines with ideal cycle of supercharged engine, write down the main problems of supercharging, especially the border of self-ignition of fuel and detonation ignition, advantages and disadvantages of different methods of supercharging and its effect on engine efficiency. Further, there are given basic construction designs of turbochargers and air coolers and some special methods of supercharging and cooling.

The electric car as part of a smart home
Peichl, Ondřej ; Ušiak, Michal (referee) ; Štětina, Josef (advisor)
This thesis provides an overview of technologies that can be a part of an electric car. These technologies include Vehicle to Grid, Vehicle to Building, Vehicle to Home, etc. The principle, properties, possibilities of development and integration in the Czech Republic and in the world will be described for these technologies. The second part of the thesis will deal with the connection of an electric car to a smart home and its cooperation with other components of the smart home, such as home photovoltaic power plant, control system or wallbox. At the end of the thesis is designed a specific smart house, which was calculated the consumption of electricity for the household, for the electric car and also how much of this consumption can cover the home photovoltaic power plant.

Charger for lead-acid batteries
Kopuletý, Ondřej ; Procházka, Petr (referee) ; Ondrejček, Vladimír (advisor)
This bachelor‘s thesis deals with the modification, construction and testing of lead-acid battery chargers. It is described the principle of charging the batteries and individual topology of the switching power supplies. The original schematic diagram is taken from the thesis of Josef Kadlec. Diagrams of a power and control circuit have been modified. The topology of the charger is two switch forward converter with pulse transformer. The charging method is constant voltage with current limiting.

Smart Li-ion Batery
Prachař, Vojtěch ; Burian, František (referee) ; Kopečný, Lukáš (advisor)
The thesis deals with lithium accumulators with electronics, which are composed to a unit called Intelligent Battery. Within this thesis, the main features of these accumulators are explained and the circuit to monitor these accumulators has been designed and manufactured, it can disconnect them when the parameters are exceeded, and it stores the history of the battery measurement in memory. It also allows reading of current and logged battery data via UART. The computer application is designed for communication, to display the information and to adjust the battery circuit parameters. The electronics secure charging when the 24V adapter is connected according to the set parameters and it also secure balancing of the individual accumulators.
