Climate change awareness makes support in the electric vehicle market. However the main factors influencing electric vehicle adoptions besides the purchase prices are driving range, charging time and charging structures. In this regard the standardization process is studied into the EV charging market as a process achievement for setting back-end communications. In particular the role of e-Roaming protocols is investigated, assumed as the indirect roaming, in opposition to the direct roaming used in peer-to-peer connections. The European scenario, indeed, at his Status Quo is fragmented, presenting many closed networks and a multitude of business models of rapidly evolving, where electric vehicle progress varies widely from country to country and from city to city. Understanding this variation is important in identifying effective policies and actions to further accelerate electric vehicle adoption. In Europe there are some interoperability protocols that allow indirect roaming connections in the electromobility. In order to individuate a standardization process that aims at a European interoperable scenario, a qualitative analysis is carried out drawing firms’ strategies and country-by-country cases studies. In addition the support of a quantitative network analysis made it possible to identify the main players and afterwards deeply investigate their strategies and alliances.
