Integration of Communication Protocols for Electric Vehicle Charging: Functionality and Integration

EV charging stations are a critical piece of infrastructure to accelerate the transition to green and clean technologies. In recent years, the number of charging stations has grown significantly. This leads to the emergence of new problems and challenges for society, such as the management of charging processes, capacity balancing, and extended access. In this study, the basic concepts regarding standards and protocols for managing charging stations and capacities are presented. Over the years, the protocols have evolved and currently provide a variety of functionalities such as remote access, status tracking, station, and capacity control. The knowledge and development of these protocols will support easier and more adaptive use of charging stations. In addition, the current challenges that should be solved in the coming years are presented. They are related to the improvement of remote access, power balance, construction of hybrid systems of energy sources, and development of management information systems for management.
