锂离子电池Thevenin模型参数确定方法研究
Study on method of determining parameters of Thevenin model of lithium-ion battery
摘要
Abstract
One of the important effects of battery management system (BMS) is to estimate the state of the battery (SOC,SOH) quickly and accurately.But these parameters cannot be measured directly,usually the model is used to estimate these parameters.Compared to other battery models,the dynamic characteristics of the battery are described by Thevenin model,considering the battery polarization,which can descdbe the battery response characteristic more accurately and is widely used in the basic modeling of electric vehicle power battery.However,the calculation of the relevant parameters is complex.A method of least squares estimation of strong engineering practicability was proposed,which is easy to operate.And Simulink model was used to verify the accuracy of the estimation method.关键词
