Many private and public companies are moving towards fleet electrification; this new trend is significantly fostered by public strategies about decarbonization, market conditions and companies' policies for reducing their carbon footprint. Nevertheless, the impact of the electrical fleet on logistics and electrical consumptions has not been extensively evaluated in the literature. This paper aims to assess these impacts considering the data of an existing traditional fleet. The presented model takes into account several parameters and conditions and it validates different policies and design solutions. The results show that the proposed solutions would enable company managers painlessly adopting electric vehicles in their fleets.
