Abstract: In order to solve the problem that the parameters of the battery equivalent circuit model are changeable and difficult to be accurately identified, a second-order RC aero-battery model is established, and a parameter identification algorithm based on the forgetting factor recursive extended least square ( FFRELS) is proposed. In view of the problem that FFRELS can not accurately identify the open circuit voltage of the battery, a recursive model of open circuit voltage is established to realize the dynamic estimation of open circuit voltage. This method can accurately identify the battery model parameters and improve the identification precision of the open circuit voltage of the battery. Finally, the simulation results show that this method can improve the identification precision of the battery model parameters.
