Parameter Design of Powertrain and Experimental Verification of Pure Electric Vehicle

This article mainly introduces parameter design principle of pure electric vehicle power train. The model of a pure electric vehicle is established in CRUISE. Given motor system and battery system, vehicle performance on various transmission ratio was analyzed and the optimal ratio of transmission was determined. Dynamic performances and driving range of the vehicle was tested, which indicate that the error is smaller than 5% between calculated results and test datum. The rationality of established model is verified. The vehicle driving system meet the research targets, which has good dynamic performance and driving range.
