In the European electromobility framework, the interoperability of platforms and the standardization of services are becoming the main goals of researchers and practitioners. In this context, the objective of this paper is to propose innovative services for electromobility actors and stakeholders based on the definition of Virtual Sensors (VSs). A VS provides new information to the network by aggregating, elaborating and processing of existing and available electromobility data. To this purpose, each VS functioning, outputs and inputs can be described by UML diagrams. In order to show the proposed methodology, a useful VS for electromobility enhancement is presented, i.e., a personal mobility probability VS.
