增程式电动汽车动力系统匹配与仿真研究

摘要

以某款增程式电动轿车为研究车型，根据整车基本参数以及定义的动力性能参数，确定了驱动电机和动力电池的基本参数，并以整车最高车速为目标确定了增程器的标定功率和增程器发动机的输出功率。在此基础上利用ADVISOR软件对该车的动力性能进行仿真分析。仿真结果表明该车动力系统的匹配合理并满足整车动力性能需要。%The study was based on some of the extended-range electric vehicles. The basic parameters both on the powering batteries and the driving motor were determined according to the whole vehicle’s paramerters on dynamic performance. The extended-range device’s generator out putting power and its target power were confirmed and based on the vehicles max running speed. On the basis of the above, the software ADVISOR was used to make a simulation verification of powertrain matching. The results demonstrate that the scheme for the power system of the extended-range electric vehicle is feasible and meets the dynamic property’s demand.
