摘　　要：本文针对某款小型纯电动汽车,对其动力系统的重要参数进行了设计和匹配。定义了传动比设计常数,给出了传动比设计的方法和步骤。在AVL CRUISE和MATLAB中建立了模型并分别从动力性和经济性方面进行了联合仿真。结果表明动力性和经济性完全满足设计要求,本文对如何设计动力系统参数具有重要意义。Important parameters of power system are designed for a small battery electrical vehicle, which is funded in a school-enterprise cooperation project. Transmission ratio constantis defined, and transmission ratio is designed. Simulation of power performance and economy has been processed with the combination of AVL CRUISE and MATLAB. The results show that power performance and economy meet the require- ments. The research has an important significance on the method of designing parameters of power system.
