A traction battery controller of an electrified vehicle controls the traction battery based in part on a value of a non-linear circuit element of a model of the traction battery in which the value of the non-linear circuit element is estimated in part on distribution of relaxation time (DRT) information of measured impedance data of the traction battery.
