Electric and Hybrid Vehicles Analysis
Slaběňák, Patrik ; Kuchyňková, Hana (referee) ; Hájek, Vítězslav (advisor)
Nowadays, oil resources start to decrease, therefore it is necessary to think about alternative sources of energy. The result of this semester project is a basic overview of the current development of electric and hybrid cars, with potential application in normal operation and the proximity of their main characteristics, such as mileage, price and service when traveling. The energy required to operate the electric stored in batteries are recharged using the power stations, which is also devoted part of the work. The thesis focuses on the design and calculation of power consumption for a defined route of four-wheel electric wheelchair. The conclusion of the thesis deals with the future development of hybrid and electric vehicles, and with the expected trends in the field of power electronics and motors and with the propagation of hybrid vehicles to the customers.

Simulation of the energy recovery circuit function
Kubíček, Ondřej ; Ficza, Ildikó (referee) ; Nevrlý, Josef (advisor)
This bachelor thesis describes the design and optimization of a mathematical model for simulating the hydrostatic energy recovery systems. The mathematical model together with the experimental stand should be used to simulate the operating conditions of vehicles using the hydrostatic energy transmission. These include vehicles for collection of municipal waste, public transport vehicles, or for heavy construction machinery. The paper summarizes the current efforts in the design of analytical models, describes the program developed in MATLAB, and is devoted to analyzing the influence of individual input parameters on the output calculation.

Elements of experimental equipment for research energy recovery of vehicles
Vašíček, Jakub ; Jurík, Miroslav (referee) ; Nevrlý, Josef (advisor)
Bachelor thesis is focused on selection of hydraulic components for experimental device – stand for research on hydrostatic recovery of kinetic energy of heavy vehicles for civil engineering, public transportation or utility. Main supplier of hydraulic components is – Bosch Rexroth. Thesis primary pays attention to selection and comparation of hydraulic components, it does not deal witch construction or mathematical model. Part of this thesis is concerned with future development in the field of hydrostatic recovery of energy. Main purpose of experimental stand is simulation of operational conditions of heavy vehicles, to gather information about efectivity of energy recovery and to help in making suggestions in construct solution for chosen conditions. Concrete output is analysis of suitability and construct solution for road roller AMMANN AP 240 H.
