Abstract
(EN)
The battery module 1 contains an array 2 comprising a plurality of battery cells 11 that have been arrayed. Housed inside a case 12 of each of the plurality of battery cells 11 are: an electrode assembly body 13 comprising a positive electrode 21 and a negative electrode 22 layered with a separator 23 interposed therebetween; an electrolyte solution added with an overcharge additive for generating a gas by starting a reaction when the battery cell 11 has reached an overcharged state; and a current interruption device 26 for interrupting a charging current when, due to the gas generation, the internal pressure of the case 12 has reached a threshold value or greater. Fixed on an outer side surface 12a of the case 12 is a rigid member 31 for restricting, with respect to a lower limit value of the amount of gas generated which has been set beforehand according to the amount of overcharge additive added, the expansion of the case 12 in such a manner that the internal pressure of the case 12 is equal to or greater than the operating pressure of the current interruption device 26.

Le support de piles 1 contient un réseau 2 comprenant une pluralité d'éléments de batterie 11 qui ont été disposés en réseau. Les éléments suivants sont logés à l'intérieur d'un boîtier 12 de chaque élément de la pluralité d'éléments de batterie 11 : un corps d'ensemble électrode 13 comprenant une électrode positive 21 et une électrode négative 22 disposées en couches, un séparateur 23 étant intercalé entre celles-ci ; une solution électrolytique ajoutée avec un additif de surcharge pour générer un gaz par démarrage d'une réaction lorsque l'élément de batterie 11 a atteint un état de surcharge ; et un dispositif d'interruption du courant 26 permettant d'interrompre un courant de charge lorsque, en raison de la génération de gaz, la pression interne du boîtier 12 a atteint une valeur supérieure ou égale à une valeur de seuil. Un élément rigide 31 est fixé sur une surface latérale extérieure 12a du boîtier 12 pour restreindre, par rapport à une valeur limite inférieure de la quantité de gaz généré qui a été définie à l'avance en fonction de la quantité d'additif de surcharge ajouté, la dilatation du boîtier 12 de telle sorte que la pression interne du boîtier 12 est supérieure ou égale à la pression de fonctionnement du dispositif d'interruption de courant 26.
