The accumulation of electricity as an issue is becoming more important and it’s importance is constantly growing. This is due to the fact that more renewable energy sources, mainly photovoltaic and wind power plants, are being incorporated into the electricity system, causing changes in the power grid performance. Changing in the behavior of consumers of electricity can cause further changes in the network. The ability for compensations of these changes in the power grid has just accumulation systems. This Thesis for Master’s Degree presents selected storage systems and ways in which energy can be stored. Further, in this work, a model of accumulation system with management based on general conditions will be created. This model will be tested and its behavior detected under the limit conditions.

This master’s thesis deals with the influence of different carbon materials on the properties of Li-S accumulators. The theoretical part of the thesis describes primary and secondary electrochemical sources with a focus on medical applications. The second chapter deals individually with a lithium article. The main part of the thesis is the practical production of electrodes for Li-S accumulators using different types of carbon materials. The effects of these materials on the properties of accumulators are investigated to determine the most appropriate in terms of capacity and stability.

This diploma thesis deals with the design of a photovoltaic solar power station for a specific family house in the Jihlava region. The aim of the work was to get acquainted with technologies about the production of solar systems, evaluate the market in the Czech Republic and create a design of photovoltaic solar power station. Three designs of power stations were created with the help of the PV * SOL design system. Each design uses different photovoltaic cell technology. The result of each power station design is a complete finished project, which is based on many factors such as the efficiency of the entire system in a certain location, financial analysis, return on investment and more. In addition, these projects meet the conditions for the preparation of the subsidy program Nová zelená úsporám. At the end of the work, all three designed power stations are evaluated and with the help of multicriteria analysis, the best and most advantageous power station design for the given locality is determined. In the end, the idea of further development of the project is presented.

The aim of this master´s thesis was the measurement of electrical conductivity and dynamic viscosity of the electrolytes. Based on these measurements to verify Walden theorem between measured variables. Electrolytes were used on sulfolane base in combination with propylene carbonate and salt. The thesis also deals with the measuring method of dielectric properties of electrical and optical method with a refractometer. The freezing point of combination of sulfolan and propylene carbonate were determined by cryoscopy.

Master’s thesis is deals with the effect of carbon additives on the positive electrode in the NiCd batteries. It examines whether the positive electrode material enrichment of carbon additives to achieve improved internal parameters of conductivity and better contact with the electrode materials in a discharged. Galvanostatic cycling and electro-chemical impedance spectroscopy (EIS) are used for evaluation of graphite aditives.

The goal of the thesis is to study literature and to become familiar with problems of accumulators operating in the mode of hybrid electric vehicles (HEV). To work up problems of a potential impact of the influence on the system of the lead accumulator. Assemble the experimental cells with discontinuous system of parallel fins and to treat them with different operating modes. Then to evaluate the results.

The thesis includes the basic principles of lead-acid, NiCd, NiMH and Li-Ion batteries. There is a description of their features and phenomena that processes in the batteries during charging and discharging. The most important part is devoted to dynamic models of these types of batteries, the parameters that are necessary for their modeling, and testing of absolute error models. Further, the model in Matlab was created which allows the simulation of the GRID-OFF photovoltaic system using the battery model.

This master´s thesis is dealing with the theory of Li-ion accumulators and theirs charching. In this thesis has been designed accumulator tester for automatic charging and discharging of Li-ion accumulator. This tester is controlled by microprocessor.

The main aim of this work is a development of electric car. This car has fuel cells as a primary source of electrical energy which will be performed with regard to the maximum roll-out and to maximize the efficiency of hydrogen conversion into electricity. The first part is dedicated to the concept of drive as a whole, the second part is dedicated to solving vehicle dynamics. The third part describes the design of mathematical models of drive components. Part four gives the results of simulations of traffic on the route at different ways of managing fuel cells and various vehicle speeds.
