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.

Turbocharger Rotor Balancing
Šárovec, Marek ; Zubík, Martin (referee) ; Knotek, Jiří (advisor)
This bachelor’s thesis is specialized search dealing with issues of turbocharger rotor balancing. This work is divided into three main parts. First part deals with history of turbocharger and basics of turbocharger construction. Second part talks about types of unbalance and how to balance. Also, there is description of balancing machines. Last part depends on previous part because there is application of balancing on automotive turbocharger.

Preparation of Homeworks in the Course Algorithms
Felix, Martin ; Goldefus, Filip (referee) ; Lukáš, Roman (advisor)
This Bachelor's thesis is about AVL trees, which belongs to the binary search trees. Thesis contains three parts, objective of the first one is to learn student how insert nodes into AVL trees in recursive way, objective of the second part is to learn student how delete nodes from AVL trees in non-recursive way and objective of the last one is to complete student's knowledge about AVL trees . Student's results are mached with results of model solution and this evaluation establishes student's points.

Five-cylinder in-line diesel engine with viscous type damper
Procházka, Miloslav ; Novotný, Pavel (referee) ; Píštěk, Václav (advisor)
The aim of this diploma work is to design moving parts of the five cylinder inline diesel engine with given parameters, then to balance centrifugal forces and moments and design viscous torsional vibrations damper and calculate forced oscilations without the damper as well as with the damper. The designed parts are put to stress analyse by finite elements method. My design is based on similar construction of four cylinder engine Zetor.

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.

Modification of a three-cylinder diesel engine to a single cylinder test engine
Rejnuš, Miroslav ; Kučera, Pavel (referee) ; Píštěk, Václav (advisor)
The master thesis deals with the design of a single-cylinder diesel piston internal combustion test engine by modifying the initial mass-produced three-cylinder engine. The first part of the thesis is devoted to the introduction to the problems of diesel and experimental single cylinder engines. Subsequent chapters focus on the adaptation of the baseline engine itself, including balancing of inertial forces. Furthermore, the crankshaft operability is checked, including the determination of safety against high-cycle fatigue. The last chapter deals with the design of the connection of the adapted unit to the dynamometer.
