A method in charging a battery powered device (10) having a built-in charge control circuit (13) controlled by the device, and an apparatus for working the method, including said device. The device including the battery (11) is connected to a battery charger (17), and initially when the battery voltage is too low to initiate normal charging of the battery over the charge control circuit, the battery is connected to the battery charger via a current generator (25) which is switched off when the battery voltage has increased to a level which is high enough to support normal charging of the battery over the charge control circuit.
Cette invention se rapporte à un procédé permettant de charger un dispositif alimenté par batterie (10) comprenant un circuit de commande de charge incorporé (13) commandé par ledit dispositif, ainsi qu'à un appareil de réalisation de ce procédé, comprenant ledit dispositif. Le dispositif comprenant la batterie (11) est connecté à un chargeur de batterie (17) et, initialement, lorsque la tension de la batterie est trop basse pour démarrer une opération de chargement normal de la batterie sur le circuit de commande de charge, la batterie est connectée au chargeur de batterie via un générateur de courant (25), lequel est ensuite commuté lorsque la tension de la batterie est montée à un niveau suffisamment élevé pour permettre le chargement normal de la batterie sur le circuit de commande de charge.
