BATTERY PACK, AND MANUFACTURING AND DISASSEMBLING METHOD THEREFOR

To provide a battery pack, and a manufacturing method and a disassembling method therefor, the battery pack having a binding mechanism in which looseness and breakage are hard to occur if a high binding pressure is applied thereto.SOLUTION: The battery pack includes a plurality of electric cells 10 aligned in an alignment direction Z. A binding mechanism 20 which binds the electric cells 10 includes: a first end plate 21 arranged at the end part in a first direction Z1 of the arrangement direction Z; a second end plate 22 arranged at the end part in a second direction Z2; an annular first support arranged on the surface of the first end plate 21 in the first direction Z1; a second support arranged on the surface of the second end plate 22 in the second direction Z2; and a binding hoop 24 including a pair of sidewalls 24L, 24R which continuously join between the first and second supports along the alignment direction Z. Each size of the first end plate 21 and the second end plate 22 in the alignment direction Z of the binding hoop 24 applies a predetermined binding pressure to the plurality of electric cells 10 in the direction of compressing along the alignment direction Z.SELECTED DRAWING: Figure 1 【課題】高い拘束圧を加えたときでも緩みや破損が生じ難い拘束機構を備える電池パックと、その製造方法および解体方法を提供する。【解決手段】配列方向Ｚに配列された複数の単電池１０と、これら単電池１０を拘束する拘束機構２０は、配列方向Ｚの第一方向Ｚ１の端部に配置される第一エンドプレート部２１と、第二方向Ｚ２の端部に配置される第二エンドプレート部２２と、環状であって、第一エンドプレート部２１の第一方向Ｚ１の表面に配置される第一支持部と、第二エンドプレート部２２の第二方向Ｚ２の表面に配置される第二支持部と、第一支持部と第二支持部との間を配列方向Ｚに沿って連続的に繋ぐ一対の側壁部２４Ｌ、２４Ｒとを含む拘束フープ部２４と、を含む。拘束フープ部２４の第一エンドプレート部２１と第二エンドプレート部２２との間の配列方向Ｚの寸法は、複数の単電池１０に対して配列方向Ｚに沿って圧縮する方向に所定の拘束圧を加える。【選択図】図１
