Parameter Matching and Simulation Study on Powertrain for Extended-range Electric School Bus

Wen Qi Jia

Abstract

In view of powertrain parameter matching of an extended- range electric school bus,the parameter matching design methods of the powertrain were discussed based on the specifications of vehicle performance and driving range. At first,the secondary development of ADVISOR2002 simulation software was done and a model for the simulation of rear wheel drive extended-range electric school bus was established. Then the power performance of the vehicle was simulated in the Chinese typical city cycle,and the simulation results indicate that the powertrain scheme and its parameter matching are reasonable. In addition,the simulation of driving range of pure electric and extended-range were also executed with Urban Dynamometer Driving Schedule( UDDS) and Japanese 1015 Cycle( Ja1015). The simulation results show that the powertrain parameter matching can meet the driving range requirements,and that will provide reference basis for the design of extended-range electric school bus.
