E-mobility plays a key role in enabling a post-car city scenario, which aims to reduce car dependency through integrated transport and land-use strategies, alongside the promotion of active mobility, e-shared mobility services, e-transport networks, and related digital platforms. Two critical issues have emerged in advancing the e-mobility transition. First is the need for targeted incentives and policies that support the diffusion of electric vehicles (EVs), grounded in socio-spatial conditions. Second is the planning and deployment of a suitable charging infrastructure network that not only meets the spatial efficiency of supply and demand but also ensures integration with public transport systems, shared mobility services, micro-mobility, and active travel modes. Focusing on the Milan urban region (Northern Italy), this chapter investigates the spatial conditions influencing EV adoption and introduces a novel indicator—the “power gap”—to assess the adequacy of public charging infrastructure by comparing its supply with the demand derived from EV registrations, within a scenario-based perspective. This approach aims to support policymakers and stakeholders with actionable insights and strategic recommendations to guide the development of a more sustainable, efficient, and equitable charging network, thereby accelerating the broader transition to low-carbon urban mobility.
