The increasing popularity of electrified mobility services, such as shared electric vehicle fleets, is rapidly changing the landscape of the transportation industry. As a result of this growing electrification, the transportation network and electrical power grid (once considered independent) are forming a stronger bond while posing new challenges for operators of both systems. Despite the many challenges, this higher connectivity and electrification also bring new opportunities. These opportunities include the potential for enhanced synergies between these two systems, which can, in turn, increase profitability and sustainability by introducing new revenue streams. The project GAMES, which stands for Grid Aware Mobility and Energy Sharing, aims to explore viable options for highly electrified carsharing fleets and power grid hosting these systems. Ultimately, the project seeks to explore promising directions to foster a higher electrification of carsharing fleets by prescribing advanced data analytic tools to support decision-making and policy-making, finally hoping to encourage a long-lasting collaboration between the transportation and electric sectors.
