增程式电动车参数匹配与分析

针对增程式电动车研发中动力系统的参数匹配问题,以整车动力性和续航里程为设计目标,从电驱动系统、动力电池系统、内燃式增程器系统等方面出发,设计了增程式电动车动力系统参数,并以软件AVL CRUISE为仿真平台,采用增程器恒功率控制策略搭建了整车模型,验证了所设计的增程式电动车的整车动力性和续航里程。研究结果表明,车辆的最高车速、加速性能和爬坡性能满足车辆动力性能要求;车辆在10 km/h和15 km/h匀速工况下纯电动续航里程和增程模式的续航里程也满足车辆续航里程要求。

Match and analysis of range-extended electric vehicle's parameters

Aiming at the problem of powertrain parameter matching in the research and production of the range extended electric vehicle (REEV), the powertrain parameter of REEV was designed based on the targets of the vehicle dynamic performance and the driving range. Especially, the motor system, the battery system and the engine generator system were studied. And the model with a constant power management strategy was made on the AVL CRUISE simulation platform to verify the vehicle dynamic performance and the driving range. The simulation results of the maximum velocity, the acceleration performance and the climbing performance indicate that the powertrain parameter matching meet the goal of vehicle dynamic performance. In addition, the simulation results of the of pure electric and extended range driving range at the speed of 10 km/h and 15 km/h indicate that the powertrain parameter get the goal of the driving range.
