Matching And Simulation Of Powertrain Parameters Of An Electric Vehicle

The thesis, based on a pure electric vehicle converted by a fuel car, puts forward aset of performance indictors in line with current technology to meet their special trafficrequirements. And on this basis, to do the matching of parameters for drive motor, batteryand transmission in power system. In order to save time, reduce costs and improvedevelopment efficiency, the thesis uses AVL CRUISE to do modeling and simulationcalculations for the vehicle power system. AVL CRUISE is powerful simulation software,and it can complete vehicle dynamic simulation. On platform of AVL CRUISE, it sets upvehicle model, the drive motor model, battery model, the transmission model and roadmodel. And then set Full Load Acceleration, Constant Drive, Climbing Performance,Cycle Run four computing tasks and do simulation calculations and to analysis for thesimulation results. And at the same time, the thesis also does a bench test for thelithium-ion battery and also does a experimental verification for the performance ofcharge and discharge and rated capacity characteristics. Finally, through the testing ofvehicle performance, it further prove the matching parameters program for pure electricvehicle can meet the vehicle performance and also meet the thesis required targets.
