Electric buses
Forman, Tomáš ; Porteš, Petr (referee) ; Štětina, Josef (advisor)
This bachelor work is dealing with the topic of electric buses, especially from the point of view concerning the design of traction components within the vehicle. The first part of the thesis is concerned with the history and a gradual development of electric cars, especially electro buses. The second part contains the summary of the most commonly used supply chambers of electric energy; the suitability of the usage of types of these supply chambers is also mentioned. The attention is paid to the location of such supply chambers within the vehicle as well. The following chapter is dealing with the traction electric engines – their most commonly used types, and the end of the chapter is concerned with the most usual placement of such components in the vehicle with the list of plus and cons for individual kinds. In the fourth chapter are listed certain types of electric buses in the contemporary market, with the emphasis laid on the construction solution of individual producers. The last but one chapter contains the summary of what direction is the current market of electric buses moving to, and what is the current development of this field. The very last chapter is the practical one, where I am trying to show the simplified method when calculating the optimal capacity of the batteries needed for the chosen route of the electric bus.

Infrastructure for electric buses
Adamec, Matěj ; Rekem, Jakub (referee) ; Štětina, Josef (advisor)
The aim of this bachelor thesis is to examine the charging infrastructure of electric buses from the point of view of dynamically charged buses, trolleybuses, statically charged battery electric buses and their combination in the form of partial buses. In the case of the trolleybus infrastructure, the method of powering the contact wire traction, the properties of the contact wire are described, and the operation of partial buses are not omitted. For the charging infrastructure of battery buses, a detailed evaluation of the methods of connection to the charging station, charging modes and an overview of offered charging solutions from selected companies is performed. Considerable attention is paid to the possibilities of standardization and automation of connections to charging stations. In the final chapter, an approximate calculation of the optimal capacity of the battery storage for the selected line and the subsequent evaluation of the charging solution of the operating electric buses on this line is performed.

Turbine drive for charger unit of bus
Obrlík, Jan ; Fiedler, Jan (referee) ; Škorpík, Jiří (advisor)
Diploma thesis deals with use of combustion chamber to drive the electric bus charging unit. Based on the research and analysis of operation economy, a turboexpander with an air pressure tank is selected to drive the charging unit. A thermodynamic design is created for this variant. Based on this design a unit layout is proposed. Layout drawings are created for the proposed layout.

Current status of natural refrigerants for heat pumps in an electric bus
Aminian, Ali ; Vinš, Václav
The technical report provides a survey on the current status of hydrocarbons, with special focus on propane (R290), used as natural refrigerants in air‐conditioning units and heat pumps. Due to the\nexpected phase‐down of halogenated refrigerants planned in the regulation of the European Parliament no. 2022/0099/COD, alternatives such as hydrocarbons, carbon dioxide or ammonia are\nmost probably to be used in EU in the near future. A review of recent developments of HVAC units for residential use and for electric vehicles operated with natural refrigerants is presented.
