Title (EN) BATTERY MODULE
(FR) SUPPORT DE PILES
(JA) 電池モジュール
Abstract:
(EN) This battery module (10), which is an embodiment of the present invention, comprises: a plurality of cylindrically-shaped batteries (11), each having a safety valve (13) surrounded by a ring-shaped rupture section (14) rupturing when the battery internal pressure exceeds a predetermined value; an exhaust duct (15) leading gas ejected from the cylindrically-shaped battery (11) to the module exterior when the safety valve (13) has opened; and an exhaust direction regulating member provided between the exhaust duct (15) and each of the cylindrically-shaped batteries (11). The exhaust direction regulating member has a plurality of open sections which expose each of the safety valves (13), and comprises overhangs, each extending in a range that overlaps with each of the safety valves (13) in such a manner that, in each of the safety valves (13), an edge portion located on the side opposite from the exit side end section of the exhaust duct (15) is covered.
(FR) Selon un mode de réalisation de la présente invention, un support de piles (10) comprend : une pluralité de piles de forme cylindrique (11) possédant chacune une soupape de sécurité (13) entourée par une section de rupture de forme annulaire (14) qui se rompt lorsque la pression interne de la pile dépasse une valeur prédéterminée ; un conduit d'échappement (15) guidant le gaz expulsé de la pile de forme cylindrique (11) vers l'extérieur du support une fois que la soupape de sécurité (13) s'est ouverte ; un élément de régulation de direction d'échappement disposé entre le conduit d'échappement (15) et chacune des piles de forme cylindrique (11). L'élément de régulation de direction d'échappement possède une pluralité de sections ouvertes, qui exposent chacune des soupapes de sécurité (13), et comprend des dépassements s'étendant chacun dans un rayon d'action qui chevauche chacune des soupapes de sécurité (13) de telle sorte que, dans chacune des soupapes de sécurité (13), une partie bord située sur le côté opposé à la section d'extrémité côté sortie du conduit d'échappement (15) est recouverte.
(JA) 実施形態の一例である電池モジュール(10)は、電池内圧が所定値を超えたときに破断する環状の破断部(14)に囲まれた安全弁(13)をそれぞれ有する複数の円筒形電池(11)と、安全弁(13)が開いたときに円筒形電池(11)から噴出するガスをモジュールの外部に導く排気ダクト(15)と、各円筒形電池(11)と排気ダクト(15)との間に設けられる排気方向規定部材とを備える。排気方向規定部材は、各安全弁(13)をそれぞれ露出させる複数の開口部を有し、安全弁(13)のうち排気ダクト(15)の出口側端部と反対側に位置する端部を覆うように各安全弁(13)と重なる範囲にそれぞれ張り出している。
