The document presents a summary of the results achieved by research on Electric Mobility with particular reference to environmental aspects, air quality, Life Cycle Assessment, energy efficiency, regional guidelines and policies in urban areas, charging infrastructure, partial battery swap, Vehicle to the Home and Vehicle to Grid.

This summary presents the research activities carried out by RSE in the period January 2015 ÷ February 2016 in the "Electric Mobility" research project.

As for the environmental aspects and mobility scenarios, RSE has developed and applied a modeling system for the assessment of air quality in urban areas in order to assess the impact on air quality of local policies for mobility management. This allowed to quantitatively assess the role of the main management tool for the urban mobility of the city Milan: the "Area C" where circulation is restricted. The more reactive pollutants (NO, O3, NO2) have been considered. Moreover RSE used the Life Cycle Assessment (LCA) methodology to compare a set of electric cars with gasoline and diesel vehicles counterparts, in relation to the size and efficiency in the urban use. The result of the comparison reveals a general advantage in the use of electric cars, although for some categories, the internal combustion engine can have a lesser impact. RSE has also begun a study to identify solutions and promote urban policies to ensure the provision of passenger services and freight mobility, while respecting the targets for reducing energy consumption and environmental sustainability. A

s for the technological aspects and the interaction with the electrical system, RSE has been defined the optimal characteristics of infrastructure charging in the different circumstances for the need of mobility of people and goods. In this context the collaboration engaged with the Lombardy Region, engaged for the drafting of their own guidelines, allowed to apply numerous analyses developed in this project. RSE also proceeded in the analysis of technical and managerial problems and the open points in the implementation of infrastructure enabling the spread of electric vehicles.

As regards aspects of interaction with the electricity network, laboratory tests were performed on systems and components constituting the charging infrastructure for electric vehicles. Finally the architecture of a charging rack for a modular vehicular battery has been defined. Individually removable modules, rechargeable also outside the vehicle have been considered. Such a solution allows to maximize the exploitation of renewable energy production, when extracted vehicle modules are used to integrate the domestic storage. Some of these activities were carried out in synergy with the European projects Green e-Motion, Cotevos and Free-Moby.
