Integrating EVs into the Smart-Grid

Standardization efforts are currently underway to realize the Europe-wide deployment of Smart-Grids. Numerous protocols have already been standardized; each tailored to a distinct application domains. Amongst these, Smart Metering and EV charging have only recently started to converge, and the goal of the PowerUp project has been to advance such convergence. This paper presents the major results from the project. The PowerUp consortium has specified and developed an end-to-end EV to Grid communication system, respecting the applicable communications standards. After introducing the underlying system architecture for the end-to-end integration of the Vehicle-to-Grid (V2G) communications interface, we describe critical Smart-Grid integration aspects for each protocol layer within the V2G communications protocol stack. Finally, prototype test observations are presented. The outlined end-to-end integration of the V2G interface demonstrates the technological solution for ensuring that even mass-deployment of EVs would not interfere with the stability of the electric grid.
