Electric Mobility

This document summarizes the results of research activities in the field of electric mobility. Also included are activities to support national and regional institutions in the preparation of infrastructure plans, support to the AEEGSI and activities co-funded by EU electric mobility projects, in particular the Green E-Motion, INTRASME, COTEVOS and Free Moby projects.

This summary report refers to the research activities carried out by RSE during the period March 2012 – February 2013 in the “Electric Mobility” project. The project addresses the problem of electric mobility in all its aspects, continuing what was started in previous research periods. The reference framework for mobility in Italy is extended to all categories of vehicles, taking into account for each category both the total annual mileage and the demand satisfied. In this way, it is possible to compare alternative scenarios that could satisfy the same demand using alternative means: cars, motorcycles, mopeds, public transport buses, private buses, light commercial vehicles, heavy commercial vehicles, metros and trams. A likely evolutionary scenario with a horizon of 2050 has been identified. This is followed by the topic of strategic materials (SM) and the state of the art of the main technologies for their pre-treatment (mechanical and physical) and treatment (pyrometallurgical, hydrometallurgical, biohydrometallurgical) for their recovery and recycling at the end of the life of electric mobility devices, i.e. nickel-metal hydride (Ni-MH) batteries and the recovery of neodymium (Nd) contained in the permanent supermagnets of electric motors. This is followed by the study and development of optimization algorithms for the management of loads and possible aggregates in electrical distribution networks, particularly in the case of consumers consisting of electric vehicles. This is followed by characterization tests on a vehicle battery with an innovative cooling system and aging tests on supercapacitors. Given that all internal combustion vehicles could potentially be replaced by serious hybrid architectures, we want to evaluate the real efficiency of these solutions according to the different management strategies. We therefore undertook to design and build a bench demonstrator capable of validating innovative control strategies for series hybrid architectures. Last but not least, the support to the Italian Regulatory Authority for Electricity, Gas and Water (now ARERA) in the monitoring and evaluation of the “Pilot projects for the testing of public charging systems for electric vehicles” and the contribution to the institutions for the drafting of the National Infrastructure Plan for the charging of electric vehicles and the preliminary document of the Regional Environmental Energy Plan of some regions, in the part related to electric mobility. Many of these activities are carried out in synergy with the European projects Green e-Motion, Intrasme, Cotevos and Free-Moby.
