Sammendrag
In this paper, an energy model for battery electric buses (Ebus) is proposed. The model is developed based on established models for longitudinal dynamics, using event-based low-frequency data. Since the energy model is able to provide relatively accurate estimation of Ebus energy consumption with limited input requirements, it can be easily applied for future bus route planning. In addition, we have introduced a comprehensive model of the auxiliary systems, which contributes significantly to the total energy consumption ofa bus. The model for auxiliary systems includes heating, ventilation, air conditioning, and other electrical components. To evaluate the model, data was collected from 3266 trips with Ebuses operated in China and Norway. The results show that the model is able to predict the energy consumption on a trip level comparison.
