Vehicle-to-Grid as a 5G Smart Grid Vertical: Non-Technical Barriers and Implications for Communication Networks

Vehicle-to-Grid (V2G) and broader Vehicle-to-Everything (V2X) technologies are technically mature and widely demonstrated, yet large-scale deployment is constrained mainly by non-technical rather than communication or power-electronics limits. This paper targets the wireless communications community and frames V2G as a 5G-enabled smart grid vertical, linking business, governance, social, and infrastructure barriers to concrete communication-system requirements. Building on a PRISMA-guided systematic review of 974 V2G/V2X publications (2009-2025), and 162 implementation-critical studies, we adopt a four-domain framework of non-technical barriers: Business/Economic, Governance/Policy, Social, and Infrastructure/Ecosystem. Temporal and regional analyses show a shift from technical dominance to multidisciplinary integration after 2021. We translate these domains into communication requirements for V2G verticals, including fine-grained metering and settlement, protocol interoperability (e.g., ISO~15118, OCPP), privacy-by-design data governance, latency- and reliability-differentiated services, and edge-cloud partitioning for flexibility control. The results demonstrate that 5G design for V2G cannot be a purely technical optimization task and must integrate socio-technical constraints from the outset, suggesting research directions for sustainable, data-driven V2G communication architectures.

Enabling Intelligent Bidirectional Charging: A Real-World Communication Interface Between Electric Vehicles, Charging Infrastructure, and a Control Optimizer

This paper presents the real-world implementation and field validation of a user-aware bidirectional electric vehicle (EV) charging system developed within the Mobilities for EU and DymoBat projects in Dresden. Building on earlier simulation frameworks, the system enables transition from conceptual models to operational deployment in urban environments. To support grid flexibility and sustainable mobility, the solution combines real-time vehicle and user data with a centralized optimization platform to enable dynamic charging and discharging decisions. The architecture integrates a wireless On-Board Diagnostic II (OBD-II) interface and an open middleware node connected via a 5G campus network, allowing early access to vehicle state-of-charge before plug-in. A tablet-based interface captures user preferences such as departure time and energy demand, which are incorporated into the optimization together with grid conditions. A key contribution is a multi-level communication architecture linking the EV, charging station, user interface, and grid control center using the Open Charge Point Protocol (OCPP). The system integrates software, embedded hardware, and network communication for real-time charging management. Field deployment at Ostra Sport Park in Dresden demonstrates feasibility, improved load balancing, and robust vehicle-to-grid operation. The results show that early data acquisition and predictive control can enhance system efficiency. This work provides a practical benchmark for positive energy districts and future urban e-mobility systems.

Enabling Sustainable Urban Mobility: The Role of 5G Communication in the Mobilities for EU Project

This paper examines the role of 5G communication in the Mobilities for EU project, a collaborative initiative involving 29 partners and 11 pilots aimed at revolutionizing urban mobility through electrification, automation, and connectivity. Focusing on Dresden as a Lead City, we explore the integration of 27 innovative solutions, including autonomous freight transport, eBuses, and charging robots, using a 5G communication network as the central framework. We analyze how 5G enables seamless connectivity and real-time data processing across diverse technologies, fostering interdependencies and synergies. This approach not only provides a cohesive understanding of the project's scope but also demonstrates 5G's critical role in smart city infrastructure. We evaluate the anticipated impact on sustainability metrics such as air quality, noise levels, CO2 emissions, and traffic congestion. The paper concludes by discussing challenges and strategies in leveraging 5G for comprehensive urban mobility solutions and its potential impact on future smart city developments.

Bidirectional Charging Use Cases: Innovations in E-Mobility and Power-Grid Flexibility

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 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 stepping stones towards full Vehicle-to-Grid (V2G) implementation. Our analysis highlights the feasibility, advantages, and challenges of implementing V2X in urban settings, underscoring its significant role in transitioning to a resilient, low-carbon urban energy system. The paper concludes with recommendations for addressing technical, regulatory, and business model challenges to accelerate V2X adoption in Dresden and beyond.
