Opportunity fast-charging of e-buses: a preliminary study for the city of Savona

A transition towards electrification of the public transport sector is ongoing in many cities around the world, as a response to global warming and pollution. Therefore, in this paper, the electrification of the public transport system of the city of Savona is proposed. In particular, the study focuses only on the urban lines and it aims to compute the average energy consumption of an electric bus operating on a section of one existing line, in order to investigate the optimal location, size and number of opportunity fast chargers to install. The analysis presented shows that the correct service operation of the electric buses traveling on the examined line can be achieved by installing, in selected significant points, an overall number of 5 opportunity chargers each one characterized by a 400 kW rated power.
