电池寿命模型

发表于 2011/3/18

电池寿命预测，是当前每家打算做PHEV和EV的公司（车或者是电池）都要做的事情，许许多多研究机构和企业正在这方面投入巨大的精力和资源。市面上也有一些仿真软件工具，可以告诉你电池大概能用多少时间，前提是你要相信这个模型。

《Battery Life Estimator Manual Linear Modeling and Simulation》

电池寿命模型方面，NREL有着较多的研究，我在这里把它的一些结论进行一些整理，希望对大家有用。

对于目前电池而言，两个大的失效风险是内阻上升和容量下降，这在我的参加博客大赛 （有空帮忙投一下吧）的文章已经引用过了。



对于引起这两个退化的原因，可以见下图：



最为明显的就是放电深度（DOD），国内的某些厂家甚至玩到70%左右，这个实在让人觉得危险啊。特别是在容量退化不均匀以后，可能造成的问题将非常大。



可以看出，衰减的过程与存放时间（从出厂至回收的时间），温度（环境温度和工作温度），DOD窗口（这个参数与充放电功率有直接的关系），电压，回收标准（容量衰减）。

目前人们做的事情，就是通过各种各样的实验进行测量，并且通过数据处理后回归得到模型（关于电池模型的事情，已在文章中探讨）。



对于测试方面，很多人用数据进行了佐证，主要是温度方面的数据（电池实验实在太耗时间与金钱了，通过确定温度的影响，最后用加温度的办法提高应力，可以节约大量的时间与金钱）。

我将摘录《Cycle-life model for graphite-LiFePO4 cells》这篇文章的部分结论，这篇文章非常有趣，建议大家可以去看一下。

最后，有个兄弟收集了不少的电池模型上的论文，大家有想法的可以去看看。
