Abstract

A method for detecting a capacity of a battery, such as a traction battery of an electrified vehicle, includes varying a charge current provided to the battery and measuring a terminal voltage of the battery as the charge current is being varied. An estimator, that utilizes voltage feedback based on a model of the battery to provide state and parameter estimations of the battery, is driven with the terminal voltage to estimate a state-of-charge (SOC) of the battery. The capacity of the battery may be detected based in part on the SOC.
