Beschreibung
Zusammenfassung:	Method for charge management of units cells of a plurality of batteries interconnected with one another, the method comprising the steps consisting of: - measuring a voltage across the terminals of each unit cell of each of the plurality of batteries, - comparing the measurements of each unit cell with one another in order to determine a lowest voltage of all the unit cells of the plurality of batteries, - equalising the voltages of the unit cells for which the voltage is greater than the lowest voltage, taking as a target the lowest voltage so as to reduce a variation between the voltage of each unit cell and the lowest measured voltage, wherein the step consisting of equalising the voltages of the unit cells having a voltage greater than the lowest voltage is preceded by a step consisting of disconnecting from the other batteries at least one battery comprising a unit cell for which the voltage is to be equalised.
