Abstract
A powertrain having a traction battery is operated according to performance variables of the battery based on state variables of a reduced-order electrochemical model of the battery. The state variables are estimated by an estimator based on the battery model. A parameter of the battery model characterizing dynamics of the state variables with respect to battery operating conditions is updated by the estimator based on the battery model.
