1. A machine implemented method for estimating the solid phase potentials of the electrodes of a battery, the machine implemented method comprising:

  • providing battery voltage information and an estimated solid phase potential to a model coefficient updater;

    updating a model coefficient by utilizing the battery voltage information and estimated solid phase potential;

    providing battery current information to a battery internal variable estimator;

    providing the updated model coefficient to the battery internal variable estimator; and

    estimating the solid phase potentials by utilizing the updated model coefficient and the battery current information,wherein the method is implemented on a processing device.
