Abstract

For the construction of a second-order model, it is necessary to accurately identify five key parameters: R0, Rp, Cp, Rp, and Rd. Traditional offline parameter identification methods rely solely on fitting the curve during the quiescent period after discharge to determine these parameters. This paper employs the Particle Swarm Optimization (PSO) algorithm combined with a second-order RC discrete model to fit the operating curve, thereby enhancing the model's accuracy. In subsequent estimations, an adaptive Kalman filter is introduced to compare these two sets of parameters.
