    Abstract: A method estimates a duration of a battery performance rehabilitation phase. The method includes activating the battery performance rehabilitation phase when a power available in a battery is below a required minimum power level. The method also includes supplying a model of operation of the battery including, in a plane (BSOC, T) where BSOC denotes a state of charge of the battery and where T denotes a battery temperature, an isopower curve representing operating points of the battery enabling the battery to substantially deliver the required minimum power level, the curve separating operating points making it possible to deliver a power level above the required minimum power level from operating points enabling the battery to deliver only a power level below the required minimum power level. The method also includes estimating the duration of the battery performance rehabilitation phase from the model of operation supplied.

    Abstract: A method for managing an electrochemical accumulator or a storage battery includes determining an estimated value of a state of deterioration of the accumulator from the accumulator's history of voltage values, intensity of current flow, and temperature. The estimated value is a barycentric value of the state of deterioration calculated as a barycenter of at least two values. The at least two values include a first value indicative of the state of deterioration of the accumulator calculated by a first method and a second value indicative of the state of deterioration of the accumulator calculated by a second method different from the first method. From an initial commissioning state of the accumulator, barycentric coefficients are varied at least once to calculate the next barycentric value when a previous value of the state of deterioration of the accumulator, calculated according to the first method, has passed a first threshold.
