    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.

    Abstract: Vehicle systems and methods can include a traction battery and a controller to operate the traction battery according to current limits of a battery model identified from a battery response to a pulse of current injected into the battery while the battery is not being discharged to propel the vehicle or being charged. The pulse can have a sampling time and magnitude. The response is battery terminal voltages measurements at every sampling time during a set duration. The controller can implement a state estimator configured to output battery state uses a battery impulse response. The pulse input into the battery can be a current signal and the measured battery response can be a voltage. The controller can select a time period for the pulse input and battery measurement response to be when the controller is not charging the battery or drawing current from the battery to propel the vehicle.

    Abstract: A controller of a vehicle may be programmed to charge and discharge a battery according to a state of charge derived from model parameters defining one of a series of RC circuits that characterize frequency response of the battery to input current and that each has a time constant proportional to another of the time constants, and a proportionality parameter indicative of proportional relationship between the time constants. The proportionality parameter may be such that a ratio of the resistances of the RC circuits is equal to a ratio of the capacitances of the RC circuits.

    Abstract: A battery management system includes at least one controller programmed to, in response to a battery current becoming approximately zero, output an open-circuit voltage based on a sequence of battery terminal voltages measured during a time interval in which the battery current remains approximately zero and while a charge polarization voltage is decreasing. The open-circuit voltage may be further based on a non-linear regression of the sequence of battery terminal voltages. The non-linear regression may minimize a mean-squared error between the battery terminal voltages and corresponding battery terminal voltage estimates. The at least one controller may command the battery current to zero for the time interval. The battery management system may be included in a vehicle with a traction battery.
