Title
(EN) A BATTERY DEVICE COMPRISING A FLAME-RETARDANT ENCAPSULANT
(FR) DISPOSITIF DE BATTERIE COMPRENANT UN AGENT D'ENCAPSULATION IGNIFUGE
Abstract
(EN) A battery device (1) is provided. The battery device (1) comprises a casing (10) and a battery cell pack (20) located within the casing (10). The battery device (1) further comprises a flame-retardant encapsulant (30) located within the casing (10) and placed around the battery cell pack (20) to isolate the casing (10) from the battery cell pack (20). The encapsulant (30) forms an envelope comprising an outlet (31) coupled to a ventilation space for ventilation of gases and/or heat generated upon a malfunction of the battery cell pack (20).
(FR) La présente invention concerne un dispositif de batterie (1). Le dispositif de batterie (1) comprend un boîtier (10) et un bloc de cellules de batterie (20) disposé à l'intérieur du boîtier. Le dispositif de batterie (1) comprend en outre un agent d'encapsulation ignifuge (30) situé à l'intérieur du boîtier (10) et placé autour du bloc de cellules de batterie (20) pour isoler le boîtier (10) du bloc de cellules de batterie (20). L'agent d'encapsulation (30) forme une enveloppe comprenant une sortie (31) couplée à un espace de ventilation pour la ventilation de gaz et/ou de chaleur générée lors d'un mauvais fonctionnement du bloc de cellules de batterie (20).
