In recent years, the presence of electric buses within public transportation company fleets has significantly increased. To ensure optimal fleet management, it is necessary to analyze vehicle consumption in relation to their operational conditions. This study proposes an analysis of the energy consumption of a full-electric battery bus. Energy consumption was monitored using data made available on the vehicle's CAN network, including data from the main battery and major utilities such as the traction motor, the air conditioning system (both cooling and heating), power steering, main battery chiller, and low-voltage system utilities (lights, ventilation fans, doors opening, etc.). The parameters monitored during the experimentation included the vehicle's position and, consequently, the road gradient, instantaneous vehicle speed, internal and external temperature, vehicle load (to monitor consumption under various load conditions), and the involvement of different drivers.
