Zhodnocení investice společnosti DPMO, a.s. do elektrického autobusu
Fitzová, Lenka
The topic of this thesis is evaluation of the total cost of city of Olomouc for the operation of an electric bus in comparison with a diesel bus. The evaluation was based on operating data monitored by the company. The results show that investment in an electric bus pays off only in the case of a subsidy. In conclusion, there is a recommendation for the Dopravní podnik města Olomouce, a.s., which can be used in public transport of other cities.

Vplyv faktorov vonkajšieho prostredia na vývoj a predaj elektromobilov vo vybraných krajinách EÚ
Uher, Lukáš
Uher, L. Impact of external factors on sales and development of electric vehicles in selected EU countries. Bachelor Thesis. Brno: Mendel university in Brno, 2018. The main issue of this Bachelor´s thesis is a determination of external factors in-fluencing electric vehicles sales and evaluation the main reasons in differences between sales figures of this type of vehicles among EU countries. The theoretical part covers evaluation of the influence of transport on environment with regula-tions and targets of EU in a transportation sector. Furthermore, this part contains information about sales figures of electric vehicles. The practical part focuses con-sequently on examination of the connections between the listed factors and elec-tric vehicles sales by PEST analysis. The conclusion brings the evaluation of the acquired results and potential of future sales increase of electric vehicles among the listed countries.

Battery pack for an electric car
List, Jaroslav ; Kalivoda, Milan (referee) ; Polzer, Aleš (advisor)
Thesis deals with the design of a battery box with lithium-ion technology, for the largest possible driving range of the BUT SuperEL II electric car. Based on the analysis of the electric vehicle available space and the parameters of the electronic system, the maximum size of the entire set of 84s130p batteries was designed. 18650 cells with NMC technology were selected due to the very high gravimetric and volumetric density, which reaches 274 Wh/kg and 564 kWh/m3. The total nominal capacity of the designed battery boxes in the electric car is 138 kWh. The total gravimetric energy density of the designed box is 215.6 Wh/kg. It allows the electric car to reach the theoretical range with a consumption of 14 kWh/100 km of almost 1000 km. The individual battery modules of the battery box are controlled for optimal operating conditions by means of a BMS. The whole set is divided into 5 battery boxes. These boxes are manufactured using the technology of bent welded sheets from aluminum alloy EN AW 1050A and steel 1.4301. FEM analyzes were performed to verify the mechanical strength of the designed structure. The work also deals with the design of battery modules and their connection.

Energy efficiency of hydrogen utilization in transport
Mikulenka, Karel ; Kučera, Pavel (referee) ; Vopařil, Jan (advisor)
This bachelor thesis analyses current possibilities of hydrogen usage in transport. Hydrogen is by scientific community viewed as a possible answer to ever growing emissions from transport and their negative affect on the environment. The work introduces the most significant advantages of hydrogen usage as a fuel in comparison to its counterpart combustion engine and battery vehicles. Two means of obtaining energy from hydrogen in a vehicle itself shall be described which are hydrogen combustion and fuel cells. Further shall be made analysis of current possibilities for potential end customer pertaining vehicle and fuel availability. In the end is given a general description of hydrogen transport implementation in Czech Republic and its energetic cost and efficiency within an overall hydrogen economy.

Infrastructure for electromobility
Smutková, Karolína ; Böhm, Michael (referee) ; Štětina, Josef (advisor)
This thesis deals with the issue of charging electric vehicles, including a number of sub-questions. It provides an overview of current charging stations, connectors, communication between vehicle and charger during charging and of the resulting price for charging. It also takes into account the need for large amounts of energy mostly from renewable sources, coupled with battery storage facilities. The last point is a comparison of current electric vehicles mainly by battery capacity, price and range. The whole thesis is primarily related to the territory of the Czech Republic.

The use of soft computing as support for business decision-making
Pekárek, Jan ; Jašek, Roman (referee) ; Lenort, Radim (referee) ; Zinecker, Marek (referee) ; Dostál, Petr (advisor)
The presented dissertation deals with the problem of deploying the charging infrastructure for electric vehicles in the Czech Republic. The core of the thesis is a mathematical optimization model, which is implemented in the language of MATLAB computing software. The model consists of several sub-units representing separate models of studied sub-problems. The individual chapters of the work describe successively these sub models. The sub models are: demand model of the charging service, model of charging supply, charging simulator model, optimization model and its resolving optimization method. The optimization model is accelerated by parallelization on the graphics card. The optimization method is designed as a case-specific implementation of genetic algorithms on a population of tree-structured individuals. The final chapter deals with an economic aspect of the problem under consideration, the implications of the findings and the role that the optimization model plays in the context under consideration. The main benefit of the work lies in the formulation of the problem as a mathematical model, the accompanying analyses and the provided justifications. Any user with updated data can then use this work along with the attached scripts to find answers to questions about the relationship between electromobility and the charging infrastructure.
