Abstract
(EN)
In accordance with an example embodiment of the present invention, there is provided an apparatus comprising monitoring unit (102) and a charging control unit (104). The monitoring unit is configured to monitor at least one data acquisition source of a device (100) operated by a rechargeable battery (114) and to estimate a context of the device based on data acquired from the at least one data acquisition source. The charging control unit (104) is configured to dynamically adjust charging voltage and charging current applied to the rechargeable battery (114) based on the estimated context of the device acquired from the monitoring unit (102). The battery (114) comprises at least one battery cell.
(FR)
L'invention concerne, selon un exemple de mode de réalisation, un appareil comprenant une unité de surveillance (102) et une unité de commande de charge (104). L'unité de surveillance est conçue pour surveiller au moins une source d'acquisition de données d'un dispositif (100) exploité par une batterie rechargeable (114) et pour estimer un contexte du dispositif d'après des données acquises depuis la ou les sources d'acquisition de données. L'unité de commande de charge (104) est conçue pour régler dynamiquement la tension de charge et le courant de charge appliqués à la batterie rechargeable (114) d'après le contexte estimé du dispositif acquis depuis l'unité de surveillance (102). La batterie (114) comprend au moins une cellule.
