Parameters Identification Method of Battery Model for Electric Vehicles under the Charging Mode
摘要
Abstract
The battery model and parameters identification are the base of the charge and discharge optimal control of electric vehicle traction batteries.And the parameters of the battery model are affected by the working condition of the traction battery.In order to model the traction battery and identify the model parameters, modeling algorithm of traction battery and parameters identification method were studied in this paper.A variable order equivalent circuit model was established, which is based on the electrode impedance spectrum theory.A parameter identification algorithm was proposed, which is based on the forgetting factor recursive extended least square (FFRELS).A selection algorithm for the optimal order of the battery model was built, which is based on the Bayesian information criterions (BIC).A battery open circuit voltage model that was used for calibration of the proposed parameter identification algorithm was created, which is based on the lattice gas model (LGM).In the end, the battery model parameters identification algorithm and the optimal order selection under the charging mode was achieved.Validation results show that the proposed modeling and parameters identification algorithm is efficient.关键词
