Battery monitoring and protection system
Hladík, Jan ; Červinka, Dalibor (referee) ; Knobloch, Jan (advisor)
This work deals with design of battery management system. Requirements for battery management system and its conception is discussed in the first part of the work. System is able to disconnect load or charger from battery using MOS-FET transistors. It measures battery cell's voltages and is capable of passive balancing. Microcontroller is used for data processing and system control. Schematics, printed circuit board layout and control algorithm was designed. Prototype of the battery management system was then manufactured and tested.

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.

Process optimalization and lean implementation in the manufacturing company ADC Czech Republic s.r.o
Mauer, Jindřich ; Obdržálek, Radim (referee) ; Strejček, Jan (advisor)
This Master's thesis deals with the optimilization of the production process of the firm ADC Czech Republic s.r.o. The first part the tesiis focused on the research study of the issue, which is used in the practical part. The second one is devoted to brief introduction of the company ADD Czech Republic and the introduction of the product, that is engineered on the production line. The next chapter is divided into three parts. The first chapter creates an analysis of actual condition. The second deals with the implementation of the proposial. Finally, the third part is focused on other possible proposals, which have not been properly worked out

New system proposal for the balancing of assembly line powered door operation of rail vehicles
Kolečkář, Jan ; Zemčík, Oskar (referee) ; Kubík, Roman (advisor)
This work deals with the measurement time frames and then balancing of assembly line in the company IFE-CR in segment drive units rail vehicles. The first part of thesis is focused on methods of work measurement, method improving quality eight disciplines problem solving and one of the many basic methods lean production 5S. The second part of thesis is introducing company, company's history, products and distribution drive units for rail vehicles. The following part is focused a distribution of production hall, description of workplaces and detailed description of assembly line. The practical part is focused on time frames of assembly operations and theirs compare before and after balancing of assembly line. The last part of the thesis deals evaluation of results balancing of assembly line with focus on productivity.

Intelligent BMS for lithium batteries
Vašíček, Jakub ; Kazda, Tomáš (referee) ; Vyroubal, Petr (advisor)
This thesis is focused on design of electronic system called BMS, which is necessary for lithium batteries safety operation. The first part contains a brief description of lithium battery design. The following is an overview of the main parameters of this type of batteries. The next part describing various methods of state of charge (SoC) estimation and the ways to ensure uniform charge of each cell. Based on the theoretic analysis, the block diagrams for individual parts of BMS were designed. The following describing device assembly and design of control algorithm. The last part is devoted to measurement of achieved attributes. In conclusion, results of the work are discussed and possibilities of future improvements are suggested.
