Title
(EN) CHARGING CONTROL
(FR) DISPOSITIF DE COMMANDE DE CHARGE
Abstract
(EN) It is an object to provide a charging control device. In an embodiment, a device comprises: a detector con- figured to detect a charging current of a battery of an electrical device and to determine charging current values in relation to the charging current; a switch configured to connect and disconnect the charging; a controller configured to detect a maximum value of the charging current values; after detecting the maximum value, the controller is further configured to detect a threshold current value of the charging current values; after detecting the threshold current value, the controller is configured to detect a change of subsequent values of the charging current values, and based on the change to detect whether the change exceeds a threshold change value; after detecting the exceeding of the threshold change value, the controller is further configured to control the switch for disconnecting the charging. Other embodiments relate to a method and a computer program for controlling a charger device.
(FR) L'objet de l'invention est de fournir un dispositif de commande de charge. Selon un mode de réalisation, un dispositif comprend : un détecteur conçu pour détecter un courant de charge d'une batterie d'un dispositif électrique et pour déterminer des valeurs de courant de charge par rapport au courant de charge ; un commutateur conçu pour connecter et déconnecter la charge ; un dispositif de commande configuré pour détecter une valeur maximale des valeurs de courant de charge ; après la détection de la valeur maximale, le dispositif de commande est en outre configuré pour détecter une valeur seuil de courant des valeurs de courant de charge ; après la détection de la valeur seuil de courant, le dispositif de commande est configuré pour détecter une variation de valeurs ultérieures des valeurs de courant de charge et, sur la base de la variation, pour détecter si la variation dépasse une valeur seuil de variation ; après la détection du dépassement de la valeur seuil de variation, le dispositif de commande est en outre configuré pour commander le commutateur pour qu'il déconnecte la charge. Selon d'autres modes de réalisation, l'invention concerne également un procédé et un programme informatique permettant de commander un dispositif chargeur.
