Systems and methods for predicting battery power-delivery performance

Battery management systems and methods related to predicting power-delivery performance are provided. In one embodiment, a method for predicting power-delivery performance for a battery (102) includes retrieving a plurality of battery operating parameters (106, 108, 110, 112) for a selected discharge cycle, calculating an offset (114) indicative of a difference between a modeled internal resistance (118) of the battery (102) and an observed internal resistance (116) generated from a calibration discharge cycle of the battery prior to the selected discharge cycle, and outputting a battery power-delivery performance prediction (128) based on an offset-corrected internal resistance indicative of a difference between a modeled internal resistance (118) based on the plurality of battery operating parameters (106, 108, 110, 112) for the selected discharge cycle and the offset (114).
