1. A method, comprising:

  • iteratively estimating a state of charge of a battery, at least one iteration of the estimating including;

    receiving an indication of an intensity of current supplied by the battery;

    receiving an indication of a voltage supplied by the battery;

    estimating a first state of charge of the battery during the iteration based on an estimated first state of charge of a previous iteration and on the received indication of the intensity of current supplied by the battery;

    estimating an intensity of current supplied by the battery based on the received indication of the voltage supplied by the battery and on a corrected state of charge of the battery of the previous iteration, andcalculating a corrected state of charge of the iteration by adding to the estimated first state of charge of the iteration a corrective term, the corrective term being based on a product of a first correction gain and a factor representative of a difference between the estimated intensity of current and the received indication of the intensity of current supplied by the battery.
