The invention refers to a control device (6) for controlling charging of a rechargeable battery (2), the control device (6) comprising a rechargeable dummy cell (11), a first circuit (C1) configured to charge the battery and the dummy cell (11), and a second circuit (C2) configured to measure the open circuit voltage of the dummy cell (11). The control device is configured to: determine the open circuit voltage (OCVd) of the dummy cell (11) by using the second circuit (C2), and determine the maximum capacity increment (ΔΑhmax) of the battery, which is to be charged until full charging, based on the determined open circuit voltage (OCVd) of the dummy cell (11). The invention also refers to a corresponding method of controlling charging of a rechargeable battery (2).

    L'invention se rapporte à un dispositif de commande (6) destiné à commander la charge d'une batterie rechargeable (2), le dispositif de commande (6) comprenant une cellule factice rechargeable (11), un premier circuit (C1) configuré de sorte à charger la batterie et la cellule factice (11), et un second circuit (C2) configuré de sorte à mesurer la tension de circuit ouvert de la cellule factice (11). Le dispositif de commande est configuré : pour déterminer la tension de circuit ouvert (OCVd) de la cellule factice (11) à l'aide du second circuit (C2) et pour déterminer l'incrément de capacité maximale (ΔΑhm ax) de la batterie, qui doit être chargée jusqu'à une charge complète, sur la base de la tension de circuit ouvert (OCVd) déterminée de la cellule factice (11). L'invention se rapporte également à un procédé correspondant permettant de commander la charge d'une batterie rechargeable (2).
