Abstract: The invention relates to a system for managing the charging of at least one cell of a storage battery, comprising: two separate means for comparing the voltage across the terminals of said cell with a threshold voltage; and two separate controlling means adapted to control two actuators, respectively, in order to interrupt the charging of the storage battery when said first or second comparing means detects that the voltage across the terminals of said cell exceeds the threshold voltage. One of the actuators is formed by a charger that is connected to said storage battery in order to recharge said cells.

Abstract: A system and method estimates the state of charge of a battery comprising at least two modules each provided with at least one cell. A sensor senses a series current flowing through all cells of the modules connected in series. A switching device selectively disconnects one of the modules, the other modules remaining connected in series. A calculator calculates the state of charge of the cells through which the series current flows from the integration of the series current and calculates the state of charge of each of the cells of the disconnected module from an open circuit voltage thereof.

Abstract: A method for managing an authorized operating range of a battery, the authorized operating range being limited between a minimum level and a maximum level of state of charge of the battery. The method includes estimating a state of health in power of the battery, the state of health in power characterizing capacity of the battery to supply a minimum required power level across an entirety of the operating range; and determining the minimum level of state of charge of the battery in accordance with the estimated state of health in power, the minimum level of state of charge being increased when the state of health in power decreases.

Abstract: A method manages a state of charge of a traction battery of a rechargeable hybrid vehicle including a hybrid power train to provide propulsion. The battery being capable of operating according to a first operating mode over a state of charge range, of which an amplitude is bounded by predefined maximum and minimum state of charge values, in which the battery supplies substantially all power necessary for propulsion, and a second operating mode, in which the state of charge of the battery is kept substantially constantly around an equilibrium state of charge value. The method includes estimating an ageing state of the battery, comparing the estimated ageing state of the battery in relation to a given ageing state threshold, and reducing the amplitude of the state of charge range linked to the first operating mode when the ageing state of the battery rises above the given ageing state threshold.

Abstract: A method for estimating a state of health of an electrochemical cell for storing electrical energy includes applying at least one current strength peak to the cell, the current peak passing through the cell, measuring a variation, as a function of a time t elapsed after the application of the current peak, of voltage U at the terminals of the cell, and calculating at least one coefficient αI1 and at least one coefficient U0,I1 such that the function √{square root over (t)}→αI1×√{square root over (t)}+U0,I1 is a linear approximation of the variation of the voltage U as a function of √{square root over (t)} for √{square root over (t)}≥C, where C>0. The method is used in electrical or hybrid vehicles.
