摘要
在现有纯电动汽车整车基本参数的基础上,结合对应性能指标要求及汽车行驶过程中对动力性及经济性的要求,进行纯电动汽车动力性能参数的设计匹配。在获得建模所需的参数后,利用MATLAB软件的Simulink模块,建立纯电动汽车整车动力仿真模型,并验证其合理可用。为提高模型的通用性及实现较好的直观可视性,在所建模型上增加数据计算模块。经分析验证,该模型具有较好的通用性及延伸性,可为纯电动汽车初期各系统间的匹配设计提供理论依据,能够实现对纯电动汽车动力性及经济性的有效分析。
In this paper,based on the existing basic parameters of EV,Combining the corresponding performance index requirements and the driving process of the vehicle power and economic requirements,using the knowledge of vehicle theory,the power performance parameters of ev are designed and matched.After the parameters needed for modeling are obtained,the power simulation model of EV is established by using the Simulink module of MATLAB software,and its rationality is verified.In order to improve the universality of the model and achieve better visual visibility,data calculation module is added to the model.Through analysis and verification,the model has good generality and extension,which can provide theoretical basis for the matching design of various systems in the initial stage of pure electric vehicle,and can realize the effective analysis of the power and economy of pure electric vehicle.
