Abstract
(EN)
The present application discloses a method and apparatus for controlling charging of a mobile terminal. The method comprises: entering a constant-current charging mode, and obtaining a present temperature and a present current of a battery of the mobile terminal; determining a corresponding float voltage according to the present temperature and the present current of the battery; and obtaining a rated voltage of the battery, and charging the battery according to the float voltage and the rated voltage. The method charges a battery according to a float voltage and a rated voltage, increases constant-current charging time, and reduces constant-voltage charging time, thereby effectively improving charging efficiency and avoiding overvoltage damage to the battery.
(FR)
La présente invention concerne un procédé et un appareil de commande de charge d'un terminal mobile. Le procédé consiste : à entrer dans un mode de charge à courant constant, et à obtenir une température actuelle et un courant actuel d'une batterie du terminal mobile ; à déterminer une tension d'annonciation correspondante en fonction de la température actuelle et du courant actuel de la batterie ; et à obtenir une tension nominale de la batterie, et à charger la batterie en fonction de la tension d'annonciation et de la tension nominale. Le procédé charge une batterie en fonction d'une tension d'annonciation et d'une tension nominale, augmente le temps de charge à courant constant, et réduit le temps de charge à tension constante, améliorant ainsi réellement l'efficacité de charge et évitant un endommagement par surtension de la batterie.
