建立了某型纯电动汽车的动力系统结构并明确了设计要求,提出基于循环工况的动力系统参数匹配设计方法。在理论计算和分析的基础上,根据循环工况能量流对牵引电机和动力电池进行了参数匹配,并使用计算机对方案进行仿真研究,结果表明该方法行之有效。
The power system structure of a pure electric vehicle was established and the design requirements were clarified. A matching method of dynamic system parameters based on cyclic conditions was proposed. On the basis of theoretical calculation and analysis, the parameter matching of traction motor and power battery is carried out according to the energy flow of circulating condition, and the simulation of the scheme is carried out by computer. The result shows that this method is effective.
