摘要： 建立了基于MATLAB/Simulink的加装辅助能源——超级电容的电动车辆分析模型。通过CYC_CONST_45的仿真结果和实际运行结果比较，说明该模型的精度是可接受的。简要分析了多能源电动车辆的能源工作流程。通过车辆的动力性能、经济性能，包括匀速、变速、频繁加速/减速等不同的方面的分析表明，装配超级电容能够改善电动车辆的性能，并可以适当地保护蓄电池组，延长电动车辆续驶里程。

Abstract: A model of pure electric vehicle (PEV) with the ultra-capacitors, based on the software of MATLAB/Simulink, is introduced firstly. The precision of the model is acceptable by comparison with the simulation results and the actual data under the CYC_CONST_45. The work flow of the multi-source electric vehicle is olso presented laconically. The result of PEV dynamical performance, economic performance, including even speed, mutative speed, accelerating/decelerating is analyzed. The performance analysis shows that ultra-capacitors can make the performance of PEV better, protect the battery stack and prolong the distance of PEV.

Key words: Performance analysis, Pure electric vehicle (PEV), Simulation, Ultra-capacitors
