摘要
Abstract
State of charge(SOC) was one of the important parameters of battery management system of lithium-ion battery,the SOC estimation was affected by many factors of comprehensive,so it was difficult to ensure the estimation accuracy.Accurate battery model was the basis of accurate estimation of SOC,through improvements on the battery model,real-time update of the model parameters,to improve the precision of the model parameters.Correction of the extended kalman filter and combined with modified Ah counting method,reduced the influence of factors such as temperature,charge and discharge rate,so as to improve the accuracy of the SOC estimation.关键词
