Abstract
Battery electric city bus model has been created and
validated with measurement results from a full-scale city
bus prototype. The model utilises multi-physics modelling
approach with multiple-domains from friction-tyre and
transmission model to electrical drive and a simplified
battery model. For the electrical drive model, four
approaches to model the losses were studied. The modelled
and measured motor torque, speed, current in the battery
and inverter, and the bus speed were compared under two
bus line driving cycles using three payloads. The
simulated results were in good agreement with the
experimental results; the error between the simulated and
measured energy consumptions was 1.5% with the most
accurate model.
