Modeling and Simulation on Powertrain of Electric-electric Hybrid Fuel Cell City Bus

Based on the research results of the Beijing public transport drive cycle, the powertrain's configuration option and main parameters matching were done on fuel cell city bus (FCCB), and the simulation model of the whole vehicle powertrain was established using Matlab/Simulink software's mask technology in detail. The simulation on drive cycle tracking and characteristics of the power battery was carried out. It is shown that the design and parameters matching of the whole vehicle powertrain are more reasonable from simulation results, and also can meet the need of Beijing public transport operation. It is also shown that the simulation model is correct, and provides a basis for the study of the following detailed control algorithm.
