Abstract
The rapid expansion of electric vehicles (EVs) is reshaping global transportation and driving the need for advanced charging infrastructure. This paper presents a thorough review of electric vehicle (EV) charging technologies, international standards, charging station architectures, and power converter configurations. As EV adoption increases, effective integration into the electricity grid poses significant challenges related to grid stability, operation, and safety. We explore various EV charging technologies, including onboard and off- board systems, and evaluate AC-DC and DC-DC converter configurations essential for efficient energy transfer. The review covers the architectural design of charging stations, comparing AC and DC-based systems, and assesses the integration of renewable energy sources with modern charging solutions. The paper also discusses the critical role of standards and control strategies in ensuring compatibility, optimizing performance, and enhancing grid support. By analyzing the status and emerging trends in EV charging infrastructure, we identify key challenges and future research directions -aimed at improving charging efficiency and supporting grid stability. This comprehensive overview aims to provide valuable insights into the evolving landscape of EV charging, highlighting both existing technologies and future innovations.Keywords: Charging Architectures, Power Converter Configurations, International Standards, AC-DC Chargers, DC-DC Converters.
