The invention relates to a method for charging a battery comprising rechargeable cells. According to the invention, to perform the ith charge of the battery, where i≧2, connection of the charging terminals to the charger is detected triggering connection of the cells to their bypass circuit during a pre-emptive bypass time (TPji). Next, for each cell, during a second phase (Cji), the bypass circuit is disconnected from the cell until the voltage of the cell reaches a preset voltage, the pre-emptive bypass time (TPji) for the ith charge having been calculated as a function of the total connection time, during at least one preceding charge, of the bypass circuit associated with this cell, until all the cells have reached the preset voltage. At least one length of time allowing the first time (TPji) for the ith charge and/or said total connection time to be determined was memorised in a memory of the battery during this at least one preceding charge. |

1. A method for charging a battery,
the battery comprising a plurality of rechargeable cells, terminals for charging the cells and able to be connected to a charger, a bypass circuit associated with each cell, switching elements allowing the connection and disconnection of each cell to and from its associated bypass circuit and control means to control the switching elements, wherein to perform the ith charging of the battery with i greater than or equal to two, the connection of the charging terminals to the charger is detected, the detection of the connecting of the charging terminals to the charger triggering, at a first phase, the connection of the cells to their associated bypass circuit for a respective first pre-emptive bypass time associated with cell respectively;
next, for each cell, once the first time has elapsed, at a second associated phase the associated bypass circuit is disconnected from the cell until the voltage of the cell reaches a pre-set voltage which is prescribed for the cell and is nonzero; the first pre-emptive bypass time, respectively associated with the cell for the ith charging, having been calculated as a function of the total connection time, during at least one previous charging, of the associated bypass circuit to this cell until all the cells reached the pre-set voltage, at least one time period associated with the cell allowing the determination of:
the first pre-emptive bypass time for the ith charging, and/orsaid total connection time of the associated bypass circuit to this cell during this at least one previous charging, having been memorized in a memory of the battery during this at least one previous charging. |
