摘要
本文针对动力电池老化试验耗时长、工作量大等问题,在现有的电池老化研究基础上,把电池老化描述为日历老化和循环老化2种过程,并分别建立电池的日历老化模型和循环老化模型,以流经电池的电流大小为转换条件,把二者统一于电池动态老化模型。基于该模型可以估计短时间、多工况切换条件下动力电池的衰减容量。在计算机环境下完成该模型的搭建,并进行了3种不同的电动汽车充电方案下电池老化情况的仿真试验,在较短的仿真时间内模拟了电池老化的过程,降低了验证电池老化过程的成本。
To solve the problems of long time consuming and large amount of work in battery aging test,the battery aging process is described as calendar aging and cyclic aging,and the calendar aging model and cyclic aging model are established respectively based on the existing battery aging research.Taking the current flowing through the battery as the conversion condition,the two models are integrated into the dynamic aging model of the battery.Based on the dynamic aging model of the battery,the capacity attenuation rate of the power battery under short-time and multi-condition switching conditions can be estimated.The model is built in the computer environment,and the battery aging simulation test under three different charging schemes are carried out.The battery aging process is simulated in a shorter simulation time,which reduces the cost of verifying the battery aging.
