Interconnections and communications of electric vehicles and smart grids

Abstract—Huge investigations have to be made by car and power companies to realize the electro-mobility and the corresponding infrastructure. One of the critical challenges with respect to the infrastructure is the setup and deployment of a future-proof common standard for smart grids. The charging process requires a smooth communication between electrical vehicles, the power supply equipment and the smart grid. In this regard, different kind of charging locations, the charging characteristic as well as several vehicle to grid stakeholders have to be considered. This paper discusses the vehicle to grid integration and gives an overview of the current ongoing working assumption in the international joint ISO/IEC standardization of the vehicle to grid communication interface (V2G CI). Furthermore, the paper shows an approach how this communication interface can be integrated into the smart grid communication. First project results are presented demonstrating the successful implementation of this approach
