Abstract: front page image
(EN)Disclosed are an apparatus and a method for monitoring the voltage of each cell of a battery pack, a battery driven device comprising the apparatus, and a battery pack. The apparatus for monitoring the voltage of each cell of a battery pack according to the present invention comprises: a plurality of multiplexers in one-to-one correspondence with cell groups in a battery pack, the multiplexer receiving a reference potential from a relevant cell group and outputting a voltage signal for each cell within a cell group on the basis of the reference potential; a plurality of floating capacitors for sampling and then holding the voltage of each cell, in one-to-one correspondence with the plural cells included in each cell group; and a switching means for sampling the voltage of each cell onto a relevant floating capacitor of a target cell and holding the sampled voltage; and a controller for controlling the switching means by cell group to perform sampling and to hold the voltage of each cell onto the relevant floating capacitor, and then controlling each multiplexer, thereby sensing the voltage of each cell held onto each floating capacitor relevant to a cell group connected to the target multiplexer.
(FR)L’invention concerne appareil et un procédé de contrôle de la tension de bain d'un bloc-batterie, un dispositif alimenté par batterie comprenant l'appareil et un bloc-batterie. Selon l'invention, l'appareil de contrôle de la tension de bain d'un bloc-batterie comprend: plusieurs multiplexeurs en correspondance un à un avec des groupes de cellules présents dans un bloc-batterie, le multiplexeur recevant un potentiel de référence d'un groupe correspondant et émettant un signal de tension pour chaque cellule d'un groupe en fonction du potentiel de référence; plusieurs condensateurs flottants pour échantillonner puis maintenir des tensions de chaque cellule en correspondance une à une avec la pluralité de cellules présentes dans chaque groupe; et des moyens de commutation pour échantillonner des tensions de chaque cellule sur un condensateur flottant correspondant d'une cellule cible, et maintenir une tension échantillonnée; et un dispositif de commande utilisé par le groupe de cellules pour commander aux moyens de commutation d'effectuer l'échantillonage et de maintenir une tension de chaque cellule sur un condensateur flottant correspondant, puis pour commander à chaque multiplexeur de détecter la tension des cellules maintenue sur chaque condensateur flottant correspondant à un groupe de cellules raccordé au multiplexeur cible.
