摘要
在分析目前常用的锂电池SOC估算方法的基础上,按照不同温度条件下的在线辨识模型,借助改进扩展卡尔曼滤波法,对不同温度下的SOC进行估算分析.将持续变化的方差代入原扩展卡尔曼滤波算法中,完成循环工况下SOC的在线估算工作.
Abstract
On the basis of analyzing the commonly used methods for estimating the state of charge(SOC)of lithium bat-teries,an improved extended Kalman filter method is used to analyze the SOC estimation at different temperatures based on online identification models under different temperature conditions.Substitute the continuously changing variance into the original extended Kalman filtering algorithm to complete the online estimation of SOC under cyclic conditions.
