1. Social aspects of electric vehicles research : trends and relations to sustainable development goalsVasja Omahne, Matjaž Knez, Matevž Obrecht, 2021, review article Abstract: E-mobility sustainability assessment is becoming more comprehensive with research integrating social aspects without focusing only on technical, economic, and/or environmental perspectives. The transportation sector is indeed one of the leading and most challenging greenhouse gaspolluters, and e-mobility is seen as one of the potential solutions; however, a social perspective must be further investigated to improve the perception of and acceptance of electric vehicles. This could consequently lead to the European Green Deal's holy grail: faster decarbonization of the transportation sector. Another way to achieve it is by promoting more comprehensive sustainable development goals. Therefore, this paper combines a systematic review of recent research with research emphasis focused on social aspects of electric vehicles and their interconnection with specific UN Sustainable Development Goals. By knowing the current research focus mainly related with "perception" of electric vehicles and assessing their social "impact" as well as an emerging area of "user experience" and their relations with UN Sustainable Development Goals enables better insight on the current and future directions of electric vehicle social sustainability research. The current priority is identified as "climate actions". Increasingly important "sustainable cities and communities" shows potential forbecoming one of the future research, policy, and community priorities.

2. Electric vehicles as electricity storages in electric power systemsVlado Popović, Borut Jereb, Milorad J. Kilibarda, Milan Andrejić, Abolfazl Keshavarzsaleh, Dejan Dragan, 2018, original scientific article Abstract: Improvements in battery technology make electric vehicles more and more suitable for the use as electricity storages. Many benefits could be achieved by using electric vehicles for storing electricity in their batteries. This paper talks about the idea of electric vehicles as electricity storages in electric power systems. The idea has a great number of supporters, but also a significant part of the professional community believes that is unfeasible. This paper is not classified in either side and strives to give a realistic picture of this idea. For this purpose, findings from papers published in scientific journals are mainly used. There is also some information from websites, mainly for some technical issues. Partly, the opinions of the authors are present. Specificities of EVs and EPSs that enabled the birth of this idea are explained along with proposed concepts through which the idea can be implemented. Keeping with the vehicle to grid concept, issues about the implementation of the idea are considered. Achievements in the practical realization of the idea are also presented.
Keywords: electricity, electric vehicles, storages, V2G

3. Electric vehicle charging stations coverage : a study of SloveniaKlemen Prah, Mark Kmetec, Matjaž Knez, 2022, original scientific article Abstract: To promote the penetration of electric vehicles (EVs), it is of great importance to plan and construct charging stations rationally. In this sense, the state of Slovenia's charging station coverage was analysed. Using discrete and network geographic information system (GIS) models, with ArcGIS software, the density of electric vehicle charging stations (EVCSs), geographic distribution, nearness along a street network, and clustering analyses were performed. A survey conducted among Slovenian users of EVs supported the GIS analysis. It was found out that the distribution of EVCSs has an east-northeast to west-southwest directional trend. Only 13% of EVCSs are accessible from the nearest motorway at a distance of 500 meters or less. An insight into intrinsic clustering structure revealed 11 clusters of EVCSs from which the most distinct is the cluster on the area of Ljubljana. The scientific contribution of the research is in the integration of GIS, spatial analysis and the results of a survey to study the coverage of EVCSs in a certain region. Spatial analyses are carefully selected, and, in complementarity, give a comprehensive picture of EVCSs coverage. The research is important for further spatial planning of EVCSs.

5. Measurement System for Testing of Electric Drives in Electric VehiclesIztok Brinovar, Gregor Srpčič, Sebastijan Seme, Bojan Štumberger, Miralem Hadžiselimović, 2019, published scientific conference contribution Abstract: This paper deals with the implementation of a measurement system, capable of performing real-time data acquisition and control, and allows the performance analysis of electric drives used for electric vehicle propulsion. For applying the mechanical load on the shaft of the tested motor three different test bench configurations with different power and speed ranges can be used. The main objective of the measurement system is to perform routine performance tests and road simulation tests (in terms of driving cycles) of an electric drive. It provides a research environment for analysis, investigation and study of electric drives and control strategies.

7. Measurements of the characteristics of an electric motor for an electric vehicle's driveKlemen Srpčič, Gregor Srpčič, 2021, original scientific article Abstract: This paper aims to present the performance and measurement results of a load test performed on a brushless DC motor built into the wheel of a solar-powered vehicle. A brushless DC motor's theoretical background and operation are presented at the beginning of the paper. The article covers the technical specification of the solar-powered vehicle and the inbuilt brushless DC motor. The measurements were performed with the described equipment at the Institute of Energy Technology, Faculty of Energy Technology, University of Maribor. Due to the unique design of the measured electric motor, it was also necessary to make a special housing, which was intended for connecting the electric motor to the test bench. The article concludes with an analysis of the measurement results in comparison with the data provided by the electric motor manufacturer.

8. Energy consumption and grid interaction analysis of electric vehicles based on particle swarm optimisation methodKlemen Deželak, Klemen Sredenšek, Sebastijan Seme, 2023, original scientific article Abstract: The widespread adoption of electric vehicles poses certain challenges to the distribution grid, which refers to the network of power lines, transformers, and other infrastructure that delivers electricity from power plants to consumers. This higher demand can strain the distribution grid, particularly in areas with a high concentration of electric vehicles. Grid operators need to ensure that the grid infrastructure can handle this additional load and prevent overloading and consequences in terms of additional losses. As part of the task, a methodology was developed for the assessment of the electricity consumption of battery electric vehicles in Slovenia. The approach used for the calculation includes the number of electric cars, average consumption, distance travelled and efficiency of the system. Additionally, the results of the modelling approach for an integrated distribution grid model in terms of steady-state simulations are presented. The regular situation of the power losses within the distribution grid is managed together with an optimal result. In this sense, an application of the particle swarm optimisation-based strategy is suggested to minimise reliance on grid systems.

10. Input parameter analysis for electrified powertrain configurator : diplomsko deloTilen Antonio Čučko, 2020, undergraduate thesis Abstract: The basis of this thesis is the tool for power train calculation of battery electric vehicles. With the help of extensive tests and analysis, we discovered the room for possible improvements, which allowed us to upgrade the tool with a better and wider data field. Therefore, the tool is easier for engineers and various users to handle. In addition, we have separated the input file from the solver, which allows safer sharing of the documents, and equipped the input interface with additional logic for handling of wrong inputs. Furthermore, the guidance and tips for the users and additional inputs for alternative data have been added. Comparing the new tool and interface with the previous one, there are significant benefits regarding data accuracy and the difficulty level of its management.
