纯电动汽车动力系统参数匹配及性能分析

摘要电动汽车是解决当前能源短缺和环境污染问题可行的技术之一。

电动汽车是由车载动力电池作为能量源的零排放汽车。

近些年来，电动汽车的研制热潮在全世界范围内兴起，逐步向小批量商业化生产的方向发展。

电动汽车技术的发展依赖于多学科技术的进步，尤其需要解决的问题是进一步提高动力性能，增加续驶里程，降低成本。

考虑开发经费和开发周期，建立计算机仿真模型对电动汽车的性能进行仿真分析是有意义的。

本文主要研究整车的动力性匹配计算，主要的参数设计。

选择并设计出一种切实可行的纯电动汽车的动力系统设计方案。

按照动力性能要求，运用汽车理论相关知识进行传动系统主要参数设计与匹配计算。

通过对设计方案的模拟，进行方案的动力性计算。

得到计算结果后，选择了某型电机作为我们参照的对象。

建立电机仿真模型，然后再在Cruise软件里构建了循环工况试验环境、最大爬坡度实验环境和全负荷加速试验环境。

完成环境建构后，便可进行仿真实验。

在得到仿真的结果后，文章对整车在仿真实验中产生的结果进行了阐述和分析。

通过分析发现，被选择的电机并不能够满足该型电动汽车的加速能力要求，但是可以满足该型电动汽车的爬坡能力要求。

然后，依据比对电动机进行的台架试验所获得的转速--扭矩数据，分析了电机无法满足设计要求的原因，进而验证了Cruise仿真结果的可靠性。

最后，对电动汽车未来发展进行展望，对于安全、环保的节约型社会电动汽车发展必将成为发展的趋势。
