Identification Technology for State of Charge of a Battery Based on Nonlinear Equivalent Circuit Model

摘要：

　　A nonlinear equivalent circuit model for battery of electric vehicle is presented,taking into account the nonlinear effect of state of charge and battery internal parameters.Battery test and data processing for model parameter identification are designed and the models for lithium ion battery pack with current input are respectively set up with Matlab/Simulink.The experiment results demonstrate the advantages of the identification technology algorithm.
