Electric Mobility

Power System Research

The paper synthesizes the results of research activities related to electric-mobility. It includes activities on future scenarios, environmental aspects, technological aspects, standardization and support to Public Bodies.

The report describes the research activities carried out by RSE within 2017 Annual Implementation Plan of the "Electric Mobility" project. At first, the potential impact on urban air quality of some sustainable mobility measures suggested by the Milan SUMP (Sustainable Urban Mobility Plan) was analysed with a very fine detail. The modelling system allowed to evaluate the effects of some of these scenarios reported on a national scale too, also thanks to an important work of alignment between energy models and emission models. The study on Milan, moreover, focused on a particularly innovative solution, suggested by 2016 results and supported by the Municipality of Milan, known as "Ride sharing", an advanced and real-time version of the car-pooling system. The process of comparison of “traction technologies”, started in 2015 with pure LCA and continued in 2016 with the regionalization of impacts, achieved within 2017 an important arrival point, with the comparison in terms of external costs between the electric traction, petrol and diesel, enriched by the geographical allocation of those same costs. It has to be noticed that the results of these studies allow to clearly identify the overall effects of policy choices in favour of different mobility solutions.

Still in terms of policy support, in 2017 was completed the coordination work for the “Sustainable Mobility Table”, with the official publication of the "Elements for a roadmap of sustainable mobility" and the "Recommendations" delivered by the Table’s stakeholders to the Prime Minister Office, as well as with the preparation of a virtual working space for the continuation of the debate. In 2017, the "partial battery swap" system was completed and the "smart wall-box" solution confirmed good usability and interesting functionalities. Both the solutions were partially realized in 2016.

The activities carried out in 2017 also examined some new aspects, with respect to what was already started in the first two years, mostly under the stimulus of the discussion on the Sustainable Mobility Table. Therefore, some analyses were carried out on the potential synergy between the development of electric mobility and the development of renewable sources, designing a specific “2030 scenario”. In addition, preliminary analyses were performed in order to evaluate the possible transition to electric traction of heavy duty trucks and of buses for local public transport. In the first case, the charging process is continuous through a catenary system, and in the second case it is "flash" charging, studied also with regards to its impact on the network. Also these studies, even if preliminary, have provided interesting data to identify possible ways of sustainable development in the national transport sector.
