This paper explores how bidirectional charg-ing in Dresden's Ostra district can enhance grid stability, reduce energy consumption, and contribute to smart city goals. . High user acceptance is an important prerequisite for the successful integration of the bidirectional charging technology in the energy system. A field trial within the research project “Bidirectional Charging Management—BCM” offered the unique opportunity to investigate real user perceptions and. . By enabling electric vehicles to serve as mobile energy storage units, V2X offers grid stabilization and new business opportunities. We examine pilot projects and business use cases, focusing on Building Integrated Vehicle Energy Solutions (BIVES) and Resilient Energy Storage and Backup (RESB) as. . ELECTRIC CARS AS ROLLING CHARGING STATIONS: In the "ROLLEN" research project, Fraunhofer IFAM and its partners have shown how electric vehicles with bi-directional charging technology can store surplus energy from photovoltaic systems and pass it on in a targeted manner - to buildings, other. . Bi-directional charging enables the flow of electricity in two directions: from the grid to the vehicle (G2V) and from the vehicle to the grid (V2G). This is made possible through advanced power electronics and communication systems that manage the flow of energy and ensure the seamless integration. .
