This Master Thesis is the result of an eight-months internship in the headquarter of BeonD Srl, a SME Spin Off of the Politecnico di Torino born in 2012, and of the research group IEHV. The concept of this thesis was born started considering which components are emitting most pollutant on an electric vehicle. In fact, although they have been introduced as the greener solution for the automotive industry, they are not globally zero-emissions, there are components, like brakes and tires, emitting dangerous pollutant also in electric cars. The work is focused on the analysis of the possible ways to reduce the pollutants emitted by the braking system on electric vehicles, in order to reach a possible real zero-emissions drive, starting from already implemented solutions, principally regenerative braking, to find more futuristic solution to be developed and validated to be implemented in the near future with the goal of zero-emissions.
