1. A method of determining a peak power capability of a battery system comprising:

  • identifying a peak current of the battery system;

    determining a regressed ohmic resistance in a battery system model used to model the battery system;

    scaling the regressed ohmic resistance to calculate a compensated ohmic resistance of the battery system model based on the peak current;

    determining a peak power capability of the battery system based on the compensated ohmic resistance and the battery system model; and

    implementing a control action in a vehicle associated with the battery system based on the determined peak power capability.
