Public transportation with electric traction: Experiences and challenges in an Andean city

The paper studies the energy behavior of a battery-electric bus (BEB) operating on commercial routes as well technical feasibility total replacement current public transport fleet by BEBs in an Andean city. electrical variables BEB charging process are evaluated obtaining THD distortions less than 4%, values that meet national and international standards. Regarding demand, study uses estimate allows quantifying consumption 424 BEBsthat would operate 28 routes. It is estimated maximum demand during can reach 33.92 MW if charged at rate 80 kW per 19.96 charge 40 kW, whereas time range from 4 h to 9 h, respectively. daily needed power 115 MWh, which represents about 4% demanded day estimation efficiency under analysis presents vary between 0.67 0.94 km/kWh, indicator depends conditions route. article includes preference users compared conventional buses. Finally, shows feasible alternative integrate renewable sources for charging, based photovoltaic solar generation use storage systems, contribution sustainability transport. • ICE buses city Cuenca could consume MWh daily. be km/kWh km/kWh. consumed represent studied.
