Beschreibung
Zusammenfassung:	The invention relates to a method for identifying an open-circuit voltage curve of an ageing cell for accumulating electrical power. The method comprises a step (21) of identifying a reference open-circuit voltage curve, for example the indicator of the manufacturer of the cell, then a step of commanding (22) open-circuit voltage plateaus in order to then carry out a step (23) of measuring electrical data, then a step (24) of determining the loss of the capacity of the cell, and finally a step (25) of calculating an ageing function parameterised depending on the coefficient of loss of capacity and the reference open-circuit voltage curve. The invention is applicable to any device for controlling an electrical cell and any electrical device powered by the cell, for example an electrical vehicle or a portable electronic device.
