1. Comparison of emissions depending on the type of vehicle engineVladimír Rievaj, Ján Gaňa, František Synák, 2019, izvirni znanstveni članek Opis: Road transport is showing growth in the period of globalization. Its task is to transport cargo as well as people to the required location within the shortest possible time and at the lowest price. Thus, road transport plays a crucial role in enabling the globalization to be developed and improved. However, the internal combustion engine hat prevail among the vehicles of freight and passenger transport are the producers of gaseous emissions from the exhaust gases. Many developed countries of the world has committed themselves, inter alia also trough the Paris Agreement, to reduce global warming, and thus to reduce the production of harmful gaseous emissions. The result is the endeavour to replace the internal combustion engine vehicles that burn carbon fuels with the vehicles powered by electric motors consuming electric energy. The reason of such trying claims that road transport using the internal combustion engine vehicles is environmentally aggressive, and the problem would not be solved by implementation of the vehicles with electric motors. Such claim is based on the fact that an electric car does not produce any of primary emissions. From an overall perspective, it is also necessary to take into account secondary emissions that are produced during the electric energy production by which is the vehicle with electric motor powered. The purpose of this article is to assume the possibility of reducing global pollution by replacing the internal combustion engine vehicles with the vehicles powered by electric motors in dependence with producing the emissions during the production of electric energy.

2. 1D battery electric vehicle thermal management system calibration and simulation based on measurements : magistrsko deloManja Umbreht, 2024, magistrsko delo Opis: Electric vehicles are developing at an increased rate due to electrification trends and are trying to achieve the comfort level of existing vehicles with internal combustion engines. In this thesis, we considered a battery electric vehicle, with which measurements were carried out. We created a complete vehicle model in GT Suite software based on available measurements and vehicle data. The model was used to simulate measured test cases. We described the calibration procedure of standalone models and the assembly of a complete thermal model of the entire vehicle. At the end we compared three simulated test cases with vehicle measurements. We concluded that the developed vehicle simulation model behavior fits well to the measured vehicle.

3. A sustainable transport solution for a Slovenia townMatjaž Knez, Ali Naci Celik, Tariq Muneer, 2014, izvirni znanstveni članek Opis: Authorities in Slovenia and other EU member states are confronted with problems of city transportation. Fossil-fuel-based transport poses two chief problems—local and global pollution, and dwindling supplies and ever-increasing costs. An elegant solution is to gradually replace the present automobile fleet with electric vehicles (EVs). This article explores the economics and practical viability of the provision of solar electricity for the charging of EVs by installation of economical available Photovoltaic modules. A steep decline in the module, inverter and installation costs is reported herein. Present estimates indicate that for the prevailing solar climate of Celje—a medium-sized Slovenian town—the cost would be only 2 euros and 11 cents per kWh of generated solar electricity.
