Abstract
Smart and green electric vehicle charging needs digital support which integrates systems from the energy, transport and building sectors. The GreenCharge project has proposed, demonstrated, and evaluated such support in an urban living lab setting. The proposed solutions are documented in a Reference Architecture meant to act as a blueprint both facilitating the extension and integration of the involved systems in the prototype implementation and supporting replication. However, successful uptake also depends heavily on motivating and engaging relevant stakeholders. In this paper, we share our experience and lessons learned from the design, implementation, and deployment of the proposed solutions in an urban housing cooperative. Barriers and drivers regarding this innovation process are identified and recommendations to overcome the barriers are suggested. The findings are intended to help stakeholders and policy makers to develop successful strategies for sustainable electric mobility and electric energy supply.
