【0015】 上記のように、本発明の電池パックは、少なくとも以下の有利な効果を有する。電池セルスタックの底部側は下部シェルの底部板に接続され固定され、電池セルスタックのタブ側と下部シェルとの間には有発泡接着剤が充填され、電池セルスタックは安定して確実に取り付けられ、ソフトパック電池セルのタブは、短絡や熱拡散を起こしにくい。これに基づいて、仕切り部材と上部カバー及び電池セルスタックの上部側が協働して、排気通路を画定することにより、排気通路は電池セルスタックのタブ側を回避し、ソフトパック電池セルが熱暴走した場合、高温の煙を排気通路から排出することができ、電池パックの安全性能が向上する。

Abstract
To provide a battery pack capable of discharging high-temperature smoke from an exhaust passage when a soft pack battery cell runs out of thermal runaway.SOLUTION: A battery pack includes a lower shell 1, a battery cell stack 2, a foam adhesive agent 3, an upper cover and a partition member 5. The lower shell has an upper opening part and an exhaust part. The battery cell stack includes a plurality of stacked soft pack battery cells 21, and is provided in the lower shell. The bottom side is connected to and fixed to a bottom plate of the lower shell. The foam adhesive agent is filled and connected between a tab side of the battery cell stack and the lower shell. The upper cover is located on an upper part side of the battery cell stack and covers the upper opening part of the lower shell. The partition member may be interposed between the upper cover and the battery cell stack, the partition member, the upper cover, and the battery cell stack may define an exhaust passage extending along a stacking direction of the soft pack battery cells, and the exhaust passage may communicate with the exhaust part 121 in a corresponding manner.SELECTED DRAWING: Figure 2
