Analysis of SOC Estimation for Lithium Batteries Based on Temperature Influence
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.
