Title (EN) BATTERY PACK, ELECTRONIC DEVICE SYSTEM, AND METHOD OF DETECTING ATTACHMENT OF BATTERY PACK
(FR) BLOC-PILES, DISPOSITIF ELECTRONIQUE ET PROCEDE SERVANT A DETECTER LE COUPLAGE DU BLOC-PILES
Abstract:
(EN) Power is supplied through an electronic connection section (3) to an electronic device (1) from a battery pack (2) detachably attached to the electronic device (1). By using communication lines, e.g., data lines (3h, 3f) and clock lines (3i, 3g) for intercommunication between the battery pack (2) and the device (1), a CPU (2f) of the battery pack (2) recognizes the signal statuses of the communication lines to check whether the battery pack (2) is electrically connected to or disconnected from the connection section of the device (1). As a result, the number of connecting terminals used for electrically connecting a battery pack to an electronic device can be reduced, which in turn contributes to reducing the size and solving the problem of defective contacts between terminals.
(FR) Un dispositif électronique (1) est alimenté en courant par l'intermédiaire d'une partie de couplage électronique (3) par un bloc-piles (2) couplé de façon détachable au dispositif électronique (1). La mise en application de lignes de communication, par exemple, des lignes de données (3h, 3f) et des lignes d'horloge (3i, 3g), afin d'établir une communication entre le bloc-piles (2) et le dispositif (1), permet au processeur (2f) du bloc-piles (2) de reconnaître les états des signaux des lignes de communication, de manière à vérifier si le bloc-piles (2) est couplé ou non à la partie de couplage du dispositif (1). Ceci permet de limiter le nombre de bornes de couplage utilisées pour coupler le bloc-piles au dispositif électronique, ce qui contribue à réduire la dimension de ces bornes et à résoudre le problème posé par les contacts défectueux entre les bornes.
