Transitioning to electric mobility presents economic and technological challenges. In response to some of these challenges, the USER-CHI project has deployed a Smart Charging tool to implement intelligent charging strategies in the infrastructure network. Smart charging emerges as a key enabler to unlock the charging infrastructure deployment since it reduces their cost and facilitates the integration of renewable energies. This paper presents an analysis of the Àrea Metropoliana de Barcelona charging infrastructure utilization and demonstrates how the application of smart charging strategies can reduce the required power capacity while maintaining service quality. The proposed strategies enable operators to optimize energy-related costs, enhance the utilization of renewable energy sources, and actively participate in smart grid management. The analysis of charging session data reveals that longer sessions tend to have lower average power ratios, suggesting that the proposed strategies are more effective for locations with longer EV stays. Through simulations, the paper illustrates a substantial reduction in required power capacity when smart charging strategies are implemented. This research underscores the potential benefits of smart charging strategies for both Charging Point Operators and grid planners by reducing capacity-related costs and facilitating the deployment of new EV charging infrastructure. The ongoing USER-CHI project aims to further validate these strategies across various European pilot sites with diverse infrastructure sizes and optimization use cases.
