Identification of dynamic model parameters for lithium-ion batteries used in hybrid electric vehicles
Identification of dynamic model parameters for lithium-ion batteries used in hybrid electric vehicles
This paper presents an electrical equivalent circuit model for lithium-ion batteries used
for hybrid electric vehicles (HEV). The model has two RC networks characterizing battery
activation and concentration polarization process. The parameters of the model are identified using
combined experimental and Extended Kalman Filter (EKF) recursive methods. The open-circuit
voltage and ohmic resistance of the battery are directly measured and calculated from
experimental measurements, respectively. The rest of the coupled dynamic parameters, i.e. the RC
network parameters, are estimated using the EKF method. Experimental and simulation results are
presented to demonstrate the efficacy of the proposed circuit model and parameter identification
techniques for simulating battery dynamics.

Abstract
This paper presents an electrical equivalent circuit model for lithium-ion batteries used
for hybrid electric vehicles (HEV). The model has two RC networks characterizing battery
activation and concentration polarization process. The parameters of the model are identified using
combined experimental and Extended Kalman Filter (EKF) recursive methods. The open-circuit
voltage and ohmic resistance of the battery are directly measured and calculated from
experimental measurements, respectively. The rest of the coupled dynamic parameters, i.e. the RC
network parameters, are estimated using the EKF method. Experimental and simulation results are
presented to demonstrate the efficacy of the proposed circuit model and parameter identification
techniques for simulating battery dynamics.
