Zhodnocení investice společnosti DPMO, a.s. do elektrického autobusu

Fitzová, Lenka January 2020 (has links)
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.

Elektromobilita - trh a potenciál na území České republiky / Electromobility – market and potential in Czech Republic

Krausová, Liliana January 2017 (has links)
This master thesis deals with electromobility - market and potential in Czech Republic. The objective is to evaluate the situation and development of electromobility in Czech Republic via qualitative and quantitative research. That includes potential customers as well as owners of electric cars, operators of charging points, distributors of electricity, car manufactures and ministries. The basis is the comparison with leading countries in electromobility, including sales of electric cars, infrastructure and state incentives. The thesis consists of two parts. The theoretical part introduces innovations and challenges in electromobility and key factors of its success. The second part is analyzing details about individual countries empirically and via personal interviews with experts. Finally a complete overview of reasons and barriers for buying an electric car are presented together with building charging stations, a SWOT for electric cars, its infrastructure and timeline of perspective for the development of electromobility in the Czech Republic until 2030 with a recommendation of target groups for Porsche Česká republika, s.r.o.. It was found, that the situation of electromobility in Czech Republic is satisfactory and that the price is the main motive (cost savings) and barrier (price of the car) for the short-term growth. Electromobility will be developing in Czech Republic and has a great potential.

Impact of New Technologies in Energy on Households / Vliv nových technologií v energetice na domácnosti

Novák, Dominik January 2015 (has links)
This masters thesis aims to assess and evaluate the potential of home based energy storage systems for the final user. In theoretical part it therefore describes the historical development of the European power sector with the purpose of determining, what was the impact of this development on products offered by energy providers to the final consumers of electricity. Findings from this analysis are then used to design a model, which is introduced and described in the practical part of the masters thesis. This model is afterwards used to assess the profitability of home batteries implementation by three different types of households and also to determine, what are the key drivers and constraints for the adoption of energy storage systems by households.

Ekonomická a environmentální analýza využití elektromobility v osobní přepravě v České republice / Economic and Environmental Analysis of using electromobility in the Czech Republic

Sikyta, Adam January 2012 (has links)
This Diploma thesis deals with utilization of electric driven cars in Czech Republic. There are two cardinal aspects of this research. Firstly I would like to give an answer if expansion of electric driven cars could help Czech Republic with greenhouse gas emission reduction. This goal will be achieved by quantitative analysis when four different scenarios of electric driven cars expansion will be calculated. Result of this analysis will be affected by several significant aspects. The most important aspect is structure of Czech energy mix which influences environmental friendliness of using electric driven car. Outcome of this analysis will tell us if we should support electric driven cars expansion in Czech Republic. Finally Diploma thesis proves that it is possible to use electric driven vehicles as a tool for greenhouse gas emission reduction in Czech conditions. Second important aspect related with electromobility is the financial competitiveness to combustion engine driven car. In this case the goal of analysis will be set as comparative analysis of lifecycle costs. Social external costs (as greenhouse gas emissions) will be included to the analysis as well. Result of this analysis tells us what type of power drive in passenger car is financially preferable.

Návrh strategie v oblasti elektromobility v ČR pro konkrétní společnost / Proposal of electromobility strategy in the Czech republic for concrete company

Šlechta, Martin January 2011 (has links)
The subject of the thesis is to identify and assess the current status of electromobility in the Czech Republic and proposal of partly strategiy and recommendations for company Mercedes-Benz Czech Republic s.r.o. in this area. The theoretical part deals with the definition of the theory of strategic management process, especially the analysis of the external and internal area and methodologies of creation strategy. The practical part describes the characteristics of the Mercedes-Benz Czech Republic s.r.o., direct analysis of the electromobility and internal analysis of the company. Finally, there is a summary SWOT analysis and strategy formulation and recommendations in the area of electromobility for the company.

Bateriový box pro elektromobil / Battery pack for an electric car

List, Jaroslav January 2020 (has links)
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.

Rodionov, Vladislav January 2021 (has links)
The thesis focuses on the power management support of battery systems in charging mode and charging systems for electric vehicles in the LV network. The thesis includes an overview of the distribution network of the Czech Republic, means of voltage regulation and the existing legislative framework for the connection of charging systems. The thesis describes the methods of active and reactive power control depending on the voltage and frequency. The practical part focuses on the simulation of grid support at different penetration levels of BESS and EVC in MATLAB Simulink and the verification of the support function on a laboratory system. In the last part, the methods of implementing the control system for BESS and EVC operating in the LV grid are specified.

Willingness to pay for electricity-driven passenger vehicles / Willingness to pay for electricity-driven passenger vehicles

Horváthová, Inés January 2017 (has links)
This thesis analyses stated preferences for 4 different types of passenger ve- hicles (conventional, hybrid electric, plug-in hybrid, and battery electric vehi- cles). The discrete choice experiment survey was conducted in Poland in 2014. With the use of latent class model it was possible to identify and describe dis- tinct segments in the population with varying preferences for the propulsion technologies: groups with strong and weak preferences for conventional vehi- cles, segments preferring pure hybrid and plug-in hybrid electric vehicles, and a class in favour of battery electric vehicles. Even though it was found that on average consumers would require compensation up to 22,200zł (e5,311) to switch to using an electric vehicle, respective segments in the population would be willing to pay around 10,100zł (e2,417) for this change in case of pure hy- brid, around 21,400zł (e5,128) in case of plug-in hybrid, and around 92,800zł (e22,199) in case of battery electric vehicles.
