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.
