Traction Motor for a Battery Electric City Bus - Specification and Drive Cycle Evaluation, Based on Comprehensive Data Collection

Report, 2020

This internal, yet official, report serves as base for selecting the specification of a propulsion electric motor for a typical Battery Electric City Bus (BECB). The motor and the bus data are used as references in the research project Circular Economy for Electric Machines, sponsored by the Swedish Energy Agency. Additionally, found official bus drive cycles are presented and characterized, as well as four logs of real world driving of a battery electric city bus in Gothenburg, Sweden. Then, the energy consumption of the reference bus with the reference electric motor efficiency map are calculated and  compared to found official data on energy consumption of similar size battery electric city buses. Finally, related bus and electric bus market statistics and projections are summarized. In general, this report aim to provide background data for further analysis, which is why deeper analysis is left out of the report.
