FLOW boosts and demonstrates multifaceted EV smart charging and V2X integration into energy systems thanks to a range of comprehensive solutions providing answers to the needs of all actors involved. These solutions include highly replicable user-centric products, concepts, configurations and mechanisms to optimise operation. Crosssector harmonisation and standardisation is delivered to facilitate activities of stakeholders and EV users. Advanced interoperable solutions enhance planning, operation and assessment of EV charging for seamless integration into the energy system and identification of the most appropriate scenario based on a multi-criteria model, leveraging appropriate business models and tailored services. FLOW also delivers multi-actor orchestration to ensure data exchange and synchronisation across actors for VGI and EV flexibility services. These solutions are deployed in 5 demonstrations (including 2 testbeds and 3 large-scale demos) in CZ, IE, IT, DK, and ES covering a wide range of applications (e.g., V1G/V2B/V2H/V2G, public/private/semi-public, urban/rural/touristic, car/small- & medium commercial) to validate and quantify the benefits associated with enabling and valorising EV flexibility, alleviating grid challenges, and fostering mobility and energy decarbonization
