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.

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.

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.

Exploring the influence of pressure on the life of lead acid batteries for hybrid electric vehicles
Pospíchal, Martin ; Tošer, Pavel (referee) ; Bača, Petr (advisor)
The lead-acid batteries used in hybrid electronic vehicles HEV operate in high-rate mode in a state of partial charge PSoC. It occurs when the degradation mechanisms related to irreversible sulphation and negative electrodes are a limiting factor in the life of lead-acid batteries. The electrode system was applied to experimental pressure cells of different sizes. Exp. cells were subjected to measurement and evaluation of potential negative electrode, a negative active mass resistance, contact resistance of transition collector - the active mass with the evaluation and measurement of pressure fluctuations within four PSoC runs.
