Using 5G-IoT Networks for Portable Electric Vehicle Charging Stations
Mikulášek, Michal ; Jablončík, Lukáš ; Mašek, Pavel
The transition to electric vehicles (EV) as part of corporate fleets poses challenges for monitoring and reimbursing home charging activities. This paper explores the application of Internet of Things (IoT) networks to facilitate the use of portable EV charging stations by employees for home charging of corporate vehicles. The core objective is to enable precise reporting of the energy consumed during home charging sessions directly to employers, ensuring accurate compensation and energy usage tracking. This article looks at the theoretical and practical assessment of whether 5G-IoT networks are suitable for this particular case. An experimental setup was established, deploying a portable EV charging station integrated with 5GIoT connectivity to test its effectiveness in real-world residential settings under varying radio conditions. The experiment focuses on assessing the reliability of data transmission, usability in home conditions, and user experience in interfacing with the charging infrastructure. Results demonstrate the feasibility of using 5GIoT networks for this application, highlighting the potential for seamless, efficient, and secure communication between portable charging stations and corporate monitoring systems. The paper also identifies potential challenges, such as network coverage in residential areas and the challenges in device design.

Life cycle assessment methods for BEV and PHEV batteries
Dvořák, Matouš ; Pokorný, Jan (referee) ; Fišer, Jan (advisor)
Electromobility is a current topic and a way to reduce the carbon footprint not only in personal transport. The operation of an electric car does not have a direct impact on emissions compared to an internal combustion engine car. However, the issue remains the production of the battery, which contains rare metals that are very energy and environmentally demanding to extract. The aim of this thesis is to analyse the energy consumption and emission footprint of the production of different types of batteries. The thesis includes a general introduction to the Life Cycle Assessment (LCA) method, followed by a chapter on battery design and the classification of batteries according to electrode chemistry. The analysis of LCA studies of batteries shows that the least energy intensive battery in terms of production is the battery with NMC cathode and in terms of emissions it is the battery with LMO cathode. However, the results are strongly influenced by the input data, which are often different in LCA studies, so it is not possible to draw a clear conclusion. Part of the thesis deals with the analysis of the environmental impacts of battery production using different energy mixes and different types of production technologies. The work can serve as a basis for a more detailed investigation of the production part of the battery and for minimizing the environmental impact of this process.

Parking house as energy source
Novotný, Zdeněk ; Baxant, Petr (referee) ; Paar, Martin (advisor)
The bachelor’s thesis deals with the analysis of the use of selected parking houses for energy utilization. The introductory part is devoted to Vehicle-to-Grid (V2G) technology and concepts of parking lots proposed for energy purposes that enable the use of the technology. The theoretical part also includes the basic principle and implementation of wireless charging of electric vehicles, an overview of fast chargers and in the last part parking in Brno is presented. The practical part contains a comparison of 4 possible scenarios in which there was a gradual increase of individual charging stations. The output of each scenario is then the discharge and charging capacity that each parking house could provide.

Concepts of electric vehicles drivetrain
Bede, Filip ; Píštěk, Václav (referee) ; Kučera, Ondřej (advisor)
This bachelor thesis focuses on a review, analysis and comparison of current electric vehicle drive concepts that form the basis for modern electric vehicles. For a better understanding of the composition and application of the concepts, the individual elements of the powertrain have also been discussed in detail in the thesis. The thesis starts with a brief overview of important milestones in the field of electric mobility. It then continues with a detailed discussion of the electric motors, batteries and gearboxes used. These are followed by drive concepts analysed in terms of their impact on the drivability and efficiency of electric vehicles. Examples of modern electric vehicles are then given to demonstrate the concepts in practice. Finally, current internal combustion engine drive concepts are also presented and compared with EV concepts, thus providing a comprehensive view of current trends in automotive technology.

Gear trains in automotive electric drives
Vlaha, Ondřej ; Poulíček, Matěj (referee) ; Neuman, Ondřej (advisor)
This bachelor thesis deals with the research in field of gearbox applications in electric vehicles. It describes the classification of electric vehicles depending on the type of their powertrain. It also discusses the distribution of electric motor designs and analyses the parameters that affects the efficiency of the drive train. A numerical model of Tesla Model 3 was created in Matlab Simulink to illustrate the effect on powertrain efficiency when using single or dual speed transmission under different driving cycles.

Dispersion of particulate matter pollution from electric vehicles in urban areas using CFD
Lipka, Jakub ; Pospíšil, Jiří (referee) ; Linda, Jakub (advisor)
There is an opinion across the society, that electric vehicles (EV) are emission-free alternative to vehicles using internal combustion engines (ICEV). This is not true. Although electric vehicles do not produce emissions connected to internal combustion, they still produce non-combustion emissions that are emitted into surrounding air. Non-combustion emissions in question are brake wear particles (BWP), tire wear particles (TWP) and road wear particles (RWP). These emissions, due to EV’s greater mass, tend to be higher compared to ICEVs. Therefore, in this thesis, model of dispersion of non-combustion emissions generated by EVs was created using CFD consisting of two models – airflow model around EV and particle dispersion model. It was found that those emissions are captured and distributed by airflow, mainly thanks to vortices generated in the wake zone behind the vehicle. Those particles can be suspended up to 1,9 m into the air and up to 2,5 m laterally away from the vehicle. Thanks to that there is a risk of pedestrian inhaling air with high concentration of those particles in places near roads like pavements.

Concept car design for 2030
Bartůněk, Jan ; Jelenčík, Branislav (referee) ; Křenek, Ladislav (advisor)
The automotive industry is constantly evolving and facing new opportunities and challenges. In this thesis, a concept car for 2030 has been proposed that focuses on electromobility and autonomous driving mainly in terms of interior space. The proposal also addresses the trend of the constant increase in the size of cars. The concept is designed to be compact but also spacious thanks to the use of a special chassis for electric propulsion. The design has been conceived in a minimalist and sustainable way. This work represents a different approach to the future of passenger cars, and may help to further the development of electric cars.
