Title (EN) BATTERY MODULE DISCONNECT ARRANGEMENT
(FR) SYSTÈME DE DÉCONNEXION D'UN MODULE DE BATTERIE
Abstract:
(EN) The invention relates to a method and an arrangement for disconnecting one or more battery modules in an automotive battery. The arrangement for disconnecting at least one of a plurality of battery modules(11, 12, 13)in an automotive battery (10) comprises a device (14) arranged to detect that said at least one battery module is to be disconnected, and a bypass switch (15, 16, 17) arranged at each battery module, wherein the bypass switch arranged at the detected at least one battery module is controllable to bypass the at least one detected battery module via a bypass path. The arrangement further comprises a disconnect switch (21, 22, 23) arranged at each battery module, wherein the disconnect switch arranged at the at least one bypassed battery module is controllable to disconnect the at least one detected battery module from remaining battery modules, either simultaneously as, or after, the bypassing of the detected battery module.
(FR) L'invention concerne un procédé et un système de déconnexion d'un ou plusieurs modules de batterie dans une batterie automobile. Le système de déconnexion d'au moins l'un parmi une pluralité de modules de batterie (11, 12, 13) dans une batterie automobile (10) comprend un dispositif (14) disposé pour détecter que ledit au moins un module de batterie doit être déconnecté, et un commutateur de dérivation (15, 16, 17) disposé au niveau de chaque module de batterie, le commutateur de dérivation étant disposé au niveau de l'au moins un module de batterie détecté pouvant être commandé pour contourner l'au moins un module de batterie détecté par l'intermédiaire d'un circuit de dérivation. Le système comprend en outre un interrupteur général (21, 22, 23) disposé au niveau de chaque module de batterie, l'interrupteur général disposé au niveau de l'au moins un module de batterie dérivé pouvant être commandé pour déconnecter l'au moins un module de batterie détecté parmi les modules de batterie restants, ou en même temps que la dérivation du module de batterie détecté, ou après celle-ci.
