This research work focuses on solutions that promote the electric mobility diffusion in all use cases, facilitating simple and economical charging access to all types of users while guaranteeing optimal integration between EVs and the electro-energy system, the so-called Vehicle Grid Integration (VGI). Conciliating users’ charging needs with good grid operations requires to consider multiple disciplinary areas. The discussion deals with technical issues relating to hardware power electronics of charging stations, as well as digital software solutions capable of automating the dynamic control of charging (smart charging). The market aspects in which EV aggregates can play a crucial role for the electricity system flexibility are examined, along with the legislative and regulatory aspects aimed at promoting a widespread adoption of electric vehicles and related charging systems.

The different charging infrastructure technologies making them suitable for specific flexibility services are analyzed. Particular attention is paid to DC measurement devices, noting that some regulatory deficits prevent further product improvement. Electric vehicles flexibility performances reveal to be already compatible with the technical TSO requirements for many balancing services. The analysis of an EV penetration scenario in Italy quantifies their potential of traditional plants replacement for the secondary reserve service. Condominium recharge infrastructure spread still presents technical, economic and organizational obstacles.

A use case relating to a large condominium is analyzed, delving into the necessary activities, costs and suggesting regulatory initiatives to meet the administrators’ needs. The RSE monitoring and control platform for corporate charging infrastructure has been integrated with an application allowing data collection from the users and subsequent information exploitation within dynamic load programming logics. The application of ICT tools for charging infrastructure management demonstrated great potential in achieving technical and economic advantages. The activity on home recharge and the testing of Annex X of CEI 0-21 continued. A second phase of collaboration with partner companies was launched to finalize the experimentation, developing CIR devices at a commercial level and creating an aggregation platform on a national scale.
