某型纯电动汽车动力系统参数匹配研究

Matching of powertrain parameters of a pure electric vehicle

建立了某型纯电动汽车的动力系统结构和控制策略,提出了其动力系统的匹配设计方法。在理论计算和工程分析的基础上,对其电机、电池以及传动系传动比进行了参数匹配,并用计算机对实例进行了仿真研究,结果表明这种方法可行有效。

The powertrain framework and control strategy of a pure electric vehicle which uses storage cells as the power source are presented. The methods of matching powertrain parameters are described. The related parameters of storage cells, the motor and the gear ratio of the driveline are designed on the basis of theoretic and engineering analysis. Simulation of the matching is carried out, and efficiency of the powertrain and dynamic performance of the vehicle are confirmed,which shows that the matching methods are feasible.
