Using lead-acid accumulators in hybrid electric vehicle regime
Klojda, Viktor ; Vaněk, Jiří (referee) ; Bača, Petr (advisor)
This bachelor´s thesis is focused on utilization of maintenance-free lead-acid accumulators in hybrid electric vehicle regime. It describes paralel and serial draft of hybrid vehicles, their function, advantages and disadvantages. It compares lead-acid accumulators with other sorts of primary, secondary and fuel cells. Purpose of this thesis is to improve the lifetime of lead-acid batteries in PSOC regime and accompanying addition use, as an activ material of negative electrode.

Design of VUT 051 RAY aircraft with hybrid power unit
Zeman, Petr ; Bencalík, Karol (referee) ; Píštěk, Antonín (advisor)
The master´s thesis deals with a design of hybrid power unit for a small aircraft. The Introductory part goes into the problems of hybrid power unit and describes its current use in aviation. In the next part of the thesis aircrafts VUT 051 RAY and Skyleader 600 are described and the aircraft with better aerodynamic characteristic is chosen. A suitable conception of hybrid power unit is proposed for this aircraft. On the basis of the proposed conception basic flight performance are figured out. After that a weight and blance analysis are made with the chosen power unit components and thair arrangement. In the final part electric motor mounting and a frame for holding batteries are designed.

Simulation models of electric drive vehicles
Bílý, Lukáš ; Huzlík, Rostislav (referee) ; Havlíková, Marie (advisor)
The work deals with creating a DC electric motor drive. The model is composed of electrical power from the engine model and transistor pulse converter load, which are joined together and completed the anchor and regulate the flow control engine speed. Great attention was paid to the determination of losses in the load drive electric vehicles and create a model of electric power load. The real work was verified by an experimental model of an electric vehicle Car4 the available parameters.
