What is the current status of roaming protocols? What are the main challenges for roaming? Who should manage and develop roaming protocols and how? And should we move towards harmonization of roaming protocols or will it be better if multiple protocols coexist in the future? These are some of the questions researchers at the Technical University of Eindhoven are trying to answer in the project evRoaming4EU. In order to get a grip on these issues, we are conducting interviews with stakeholders all across Europe. Would you like to participate to add your perspective to our study and contribute to moving towards a fully interoperable EV charging system?
