battery electric bus is an electric bus that is powered by an electric motor and draws energy from on-board batteries. Many trolleybuses use batteries as an auxiliary or emergency power source.
First, battery electric vehicles cost much more than fossil-based buses. Also, because the batteries don’t last long enough for a full day’s work, the buses have to be swapped in and out. In order to be able to drive the same frequency as in the past with CNG/diesel buses, a municipal transport company has to maintain almost twice the number of CNG/diesel buses.
- Energy consumption model for electric buses considering limited input requirements.
- A comprehensive model of ancillaries is integrated into the energy consumption model.
- Datasets from China and Norway are used to develop and validate the model to show its applicability.
- The proposed model can provide reasonable results for planning purposes.
Better lithium-ion batteries have led to an explosion in the availability of plug-in cars. And now, thanks to relatively cheap electricity and the simplicity of the electric powertrain, electric vehicles have even more potential for use in highly cost-sensitive public transport – a concept that is only just beginning to take hold.
Because battery life is limited, the lifespan of such a vehicle is shorter than that of CNG/diesel buses. In addition, the disposal of used batteries is a problem because it is a hazardous material. This aspect has not received much attention in the vigorous push for electric vehicles.
