Abstract—This paper explores the potential of Vehicle-to-Everything (V2X) technology to enhance grid stability and support sustainable mobility in Dresden's Ostra district. By enabling electric vehicles to serve as mobile energy storage units, V2X offers grid stabilization and new business. . Instead of just consuming electricity, electric vehicles can actively contribute to grid stability through bidirectional charging. They store surplus energy - from renewable sources, for example - and feed it back into the grid or directly into buildings as required. Wind and solar power, being inherently intermittent, require flexible storage solutions.

New to the 2026 edition of the National Electrical Code (NEC), new Article 624 is being introduced to cover the electrical conductors and equipment connecting an electric self-propelled vehicle (ESV) to premises wiring for charging, power export, or bidirectional current flow. . Bidirectional electric vehicles (EV) employed as mobile battery storage can add resilience benefits and demand-response capabilities to a site's building infrastructure. The benefits of managed charging range from reducing electrical equipment upgrades. . Through bidirectional charging, part of this energy can be fed back—whether to optimize energy management in smart homes, provide backup power during outages, stabilize the electricity grid, or participate in energy trading. These developments are driving us closer to a transformative moment for EVs and their role in shaping sustainable, interconnected energy systems.

This paper introduces a novel testing environment that integrates unidirectional and bidirectional charging infrastructures into an existing hybrid energy storage system. . Bidirectional electric vehicles (EV) employed as mobile battery storage can add resilience benefits and demand-response capabilities to a site's building infrastructure. First and foremost is the increasing penetration of renewable energy sources. In her keynote speech, she explained that bidirectional. . 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. .
