The master thesis deals with the engineering design and realization of a sports electric vehicle for disabled people. The first part of thesis summarize competitive vehicles on market and also the necessary theoretical knowledge for the design phase. After analyzing the research and determine the resulting vehicle concept follows the draft design. In this section based on calculations was chosen the solutions and necessary components for a vehicle. The following section describes the structure of the vehicle in implementing selected components. In conclusion, the evaluation of the proposed solution.

This thesis deals with charging stations for electric bicycles powered by renewable energy. The aim of this work is to make a proposal for the hybrid charging stations for electric bicycles, which will work independently and, if necessary, will be backed up by a network. In this thesis is entered theoretical information on the issue of electric bicycles, the batteries, charging stations, the connectors of chargers, and photovoltaic systems. The practical part of this thesis is the basic design of the charging station and its design of the mathematical model of the individual parts in Simulink program, which are linked to the actual design of the charging station. In conclusion, this thesis deals with energy and economic analysis of the proposed system, therein included various methods of assessing investment recommendations of appropriate processing methods and overall assessment of the subject.
