Real consumption of primary energy of plug-in hybrid and electric cars
Bochníček, Ondřej ; Pokorný, Jan (referee) ; Fišer, Jan (advisor)
The topic of bachelor thesis is to evaluate a consumption of primary energy in electric cars and plug-in hybrids depending on the place of the operation and also to compare a particular representative with similar classic cars with combustion engine. Another criterion used for evaluation is the emission of carbon dioxide for one driven kilometer. For the consumption of primary energy in electric cars and plug-in hybrids is essential to know how is the electricity produced in the chosen area. With the energy mix of each state, characteristics of given ways of producing electricity and consumptions of selected cars the consumption of primary energy of selected cars and emission of carbon dioxide for one driven kilometer were determined. From the computed data results, that the lowest energy consumption have the electric cars driven in countries with dominant representation of renewable energy sources. Conversely the worst conditions are in the countries with high part of fossil fuels in electricity production. From the comparison of single electric cars and plug-in hybrids with classic cars results that electric cars or plug-in hybrids are at the time of writing this thesis practically in all cases more energy efficient and also produce less emission of carbon dioxide.

Electric cars heating systems
Kolomazník, Milan ; Fišer, Jan (referee) ; Hejčík, Jiří (advisor)
The object of this bachelor thesis is a research concerned the electric vehicle interior heating ways. The basic terms connected with the electromobilism general problems are described at the beginning. The following part outlines the current problems that impede the wide expansion of these vehicles. The thesis sums up the direct methods of the heating using electricity and the alternative way, which is a self-sufficient heating using an internal combustion engine. It also assesses the applicability of heat loss emerging in the electric components, such as an electric motor, a frequency converter or an accumulator. Based on these findings, the various constructional drafts were created including a list of their strengths and weaknesses. The conclusion draws a comparison between each of these constructional solutions.

Analysis of traction drive for full electric vehicle
Matela, Petr ; Marušinec, Jaromír (referee) ; Solař, Martin (advisor)
The subject of my bachelor´s thesis is research and computations of the dynamics of different types of engines. The first part of it is devoted to theoretical introduction to electromobilism and electro mobiles history. The rest is about benefits and problems of electro mobiles, their current state and available energy sources. In the conclusion of this thesis there are all necessary calculations and the dynamics of three different engine types is solved and compared.
