Abstract

To accurately evaluate the feasibility of operating pure electric bus on specific routes, a driving cycle with 1 800 s was defined with the method of speed-acceleration probability distribution statistics based on Hongkong No.53 bus routine spectrum data. Then the vehicle performance was studied with simulation method in Matlab/Simulink, and compared with the actual results. The rationality of the methodology and results was finally confirmed. The results show that the driving range of the vehicle under the customized driving cycle is about 22.6 km longer than that under the C-WTVC cycle, and the electricity consumption of 100 km is 20.8 kW·h less.The deviation of the measured results from the simulation results under the customized conditions is less than 4.2%, and the deviation from the results under the C-WTVC conditions is more than 13.0%, which indicates that the performance of the electric vehicle under the customized cycle has a higher degree of conformity to the results of real road test. The developed research method can provide important theoretical support for the road adaptability study of new energy electric vehicles in different environments, especially for the road conditions in the target export area.
