Potential impacts of increasing Chinese dominance in the electric vehicle industry
Čejchan, Jakub ; Semerák, Vilém (advisor) ; Veruete Villegas, Iñaki Alberto (referee)
This thesis aims to measure the potential impacts of the Chinese electric vehicle expansion on the automotive industry of the European union. Firstly it intro- duces the industry of electric vehicles, its supply chain and the development on the global scene, specifically in China and Europe. The potential effects are further estimated using the Global extraction method as a modification of the original Hypothetical extraction method in the input-output framework. It simulates the scenario in which automotive industry, represented by the sec- tor Motor vehicles, trailers and semi-trailers, of all member countries of the European Union are to be replaced by the Chinese automotive industry. This method was applied on the OECD inter-country input-output tables (ICIO) in combination with FIGARO tables provided by Eurostat. The results are then presented in the total output measures and additional component representing the value spent on employees, estimating the most affected sectors and coun- tries in this area, connected with inter-sector linkages. Such estimations point out the industries and countries that could be endangered, in the case the transition to electric vehicles would result in Chinese dominance throughout the global automotive industry. Keywords Electric vehicles, motor vehicles,...

Design of an experimental facility for battery analysis
Kvasnička, Karel ; Sedlák, Petr (referee) ; Majzner, Jiří (advisor)
Assignment of bachelor´s thesis is to create experimental workplace for analysis of batteries. To find out the condition and the capacity of a battery we have to discharge and charge the battery and measure the voltage and the current. Parameters of batteries are changing with aging and usage. There are many types of batteries that are divided into two main categories, primary batteries and secondary batteries. Their properties depend on used materials and production technique. An experimental workplace was built for battery testing equipped with a regulated power supply, a electronic load, a data acquisition unit and safety components. The workplace is able to test various types of batteries. Measurements are automated with computer program.
