Title
(EN) POWER STORAGE DEVICE
(FR) DISPOSITIF DE STOCKAGE D'ÉNERGIE
(JA) 蓄電装置
Abstract
(EN) A power storage device (1) comprises: an exterior body (10) provided with an exhaust port (15) for discharging internal gas to the outside; a power storage element (100) which is accommodated in the exterior body (10) and is provided with a gas exhaust valve (105) through which the internal gas can be discharged; and a duct (40). The duct (40) is disposed inside the exterior body (10) and forms an exhaust path for guiding the gas discharged from the gas exhaust valve (105) to the exhaust port (15). The duct (40) has a first opening part (41) and second opening part (42) for connecting the inside and outside of the duct (40). The first opening part (41) is disposed closer to the exhaust port (15) than the second opening part (42), and has an opening area larger than that of the second opening part (42).
(FR) La présente invention concerne un dispositif de stockage d'énergie (1) qui comprend : un corps extérieur (10) pourvu d'un orifice d'échappement (15) pour évacuer le gaz interne vers l'extérieur ; un élément de stockage d'énergie (100) qui est logé dans le corps extérieur (10) et pourvu d'une soupape d'échappement de gaz (105) par laquelle le gaz interne peut être évacué ; et un conduit (40). Le conduit (40) est disposé à l'intérieur du corps extérieur (10) et forme un trajet d'échappement pour guider le gaz évacué de la soupape d'échappement de gaz (105) vers l'orifice d'échappement (15). Le conduit (40) comprend une première partie d'ouverture (41) et une seconde partie d'ouverture (42) pour relier l'intérieur et l'extérieur du conduit (40). La première partie d'ouverture (41) est disposée plus près de l'orifice d'échappement (15) que la seconde partie d'ouverture (42), et comprend une zone d'ouverture plus grande que celle de la seconde partie d'ouverture (42).
(JA) 蓄電装置(1)は、内部のガスを外部に排出する排気口(15)を有する外装体(10)と、外装体(10)に収容され、内部のガスを排出可能なガス排出弁(105)を備える蓄電素子(100)と、ダクト(40)とを備える。ダクト(40)は、外装体(10)の内部に配置され、ガス排出弁(105)から排出されたガスを排気口(15)に導くための排気経路を形成する。ダクト(40)は、ダクト(40)の内部と外部とを連通する第一開口部(41)及び第二開口部(42)を有する。第一開口部(41)は、第二開口部(42)よりも排気口(15)に近い位置に配置され、かつ、開口面積が第二開口部(42)よりも大きい。
