Abstract
(DE)
Es wird eine Akkupackvorrichtung (1) für eine elektrische Handwerkzeugmaschine mit einer Gehäuseeinrichtung (10) und einem wenigstens eine Pouchzelle (21, 22, 23, 24) aufweisenden Akkupack (20). Dabei sind eine Detektiereinrichtung (50) mit einem an das Akkupack (20) gekoppelten Detektierelement (52) und einem gehäusefest angeordneten Sensor (51) vorgesehen, wobei der Sensor (51) zur Detektion des Detektierelements (52) bei Unterschreiten eines definierten Abstands zwischen dem Detektierelement (52) und dem Sensor (51) ausgeführt ist. Es wird weiterhin ein Verfahren zum Betreiben einer derartigen Akkupackvorrichtung (1) beschrieben.
(EN)
The invention relates to a battery pack device (1) for a hand-held electrical power tool, having a housing apparatus (10) and a battery pack (20) having at least one pouch cell (21, 22, 23, 24). A detection apparatus (50) is provided, having a detection element (52) which is coupled to the battery pack (20) and a sensor (51) which is fixed to the housing, wherein the sensor (51) is designed to detect the detection element (52) when a distance between the detection element (52) and the sensor (51) is below a defined limit. The invention further relates to a method for operating such a battery pack device (1).

L'invention concerne un arrangement bloc de batterie (1) pour une machine-outil électroportative comprenant un dispositif de logement (10) et un bloc de batterie (20) qui possède au moins une cellule en sachet (21, 22, 23, 24). Un dispositif de détection (50) comprenant un élément de détection (52) connecté au bloc de batterie (20) et un capteur (51) monté à demeure sur le boîtier sont ici présents. Le capteur (51) est conçu pour détecter l'élément de détection (52) lors d'un passage en dessous d'un écart défini entre l'élément de détection (52) et le capteur (51). L'invention concerne en outre un procédé pour faire fonctionner un tel arrangement bloc de batterie (1).
