Analysis of Electric Vehicle Charging Process

This paper aims to introduce readers to the issues surrounding electric vehicle (EV) charging and the potential problems arising from the expanding trend of electro mobility. It defines various EV charging methods, utilizing different types of charging stations and compatible connectors. Another key focus of this work is the set of options for controlling the power of charging stations at various levels, presenting power management strategies essential for the development of electro mobility worldwide. It is also dedicated to measuring EV charging and analyzing the collected data. Through measurements conducted in the professional laboratory of the Electrical Engineering Department at the Technical University of Kosice, the paper provides an objective view on the feedback effects of charging. It analyzes the charging of one electric vehicle, simulating the process of private home charging, and by examining the current charging of two electric vehicles, it simulates the process of mass public charging. The measurement results evaluate the feedback effects of both charging scenarios and offer recommendations for practice in future charging station construction. The exploration of the electric vehicle charging analysis has yielded numerous practical experiences, especially through expert consultations with employees of Vychodoslovenska distribucna a.s. Participating in laboratory measurements at the Smart Industry Lab and accessing measuring devices and evaluation software were immensely beneficial.
