A Route Planner Service with Recharging Reservation: Electric Itinerary with a Click

In most countries the share of circulating electric vehicles (EV) is less than 1%. Beside cost issues, the detrimental factors that most discourage people from purchasing EVs are their limited range and the rather poor coverage area of the recharging infrastructure. This clearly indicates the need for higher investments in vehicular technologies and infrastructures; however, software services and applications also play a major role in the transition to electric mobility, e.g. to mitigate EV driver anxiety. In this paper we illustrate the recipe proposed by the European Internet of Energy (IoE) project toward interoperable services for large-scale EV mobility scenarios: it consists of a Service-Oriented Architecture (SoA) to collect and integrate data coming from the heterogeneous actors of the EV scenario thanks to a semantic data tier. On top of it, we describe the implementation of an advanced Route Planning service to compute the optimal path towards a destination according to user-defined parameters and goals; differently from other approaches, our tool integrates reservation mechanisms of charging slots, so that a complete planning of the itinerary can be produced. Effectiveness of the route planning service is evaluated on large-scale EV scenarios (e.g. the Italian Emilia-Romagna region) thanks to an innovative emulation-simulation platform.
