The present invention provides a method and a system for battery impedance parameter estimation by using receding horizon regression analysis. The present invention further relates to a hybrid vehicle which includes a battery pack having one or more cells and a controller configured to continuously update battery model parameter values based on generalized linear regression analysis. The analysis updates the parameters using a dataset of independent variable vectors and a dependent variable vector constructed from a series of input currents to the battery pack and corresponding voltage responses of the battery pack that fall within a moving window.
