本文运用目前较为流行的三种仿真工具来对电动汽车辐射源进行仿真分析，运用MATLAB的simulink模块对汽车电池模型等效电路进行模型的搭建与仿真分析电路电流，得到电流的表达式和仿真图，再根据对电流图形进行曲线拟合，得到电流的近似表达式。把表达式当作是时间的函数，这样就可以将电池工作时的电流导入到CST中并作为激励源进行空间的仿真分析，得到电磁波的分布图。

In this paper, we have used three popular simulation tools to analyze the radiation source of the electric car. With the tool of MATLAB simulink module, we built the model of the equivalent circuit model of car batteries and simulated the current circuit, the expression and simulation diagram of current is obtained. Using the curve fitting tool, we obtained the approximate expression for the current. We used the expression as a function of time, so that the working battery current can be imported into the tool of CST as the excitation source in the simulation analysis of spatial. Finally the diagram of the electromagnetic wave was obtained.
