Zusammenfassung: | An objective of the present disclosure is to provide a battery module that exerts a high-rate resistance. The battery module (1) disclosed herein has a plurality of submodules (10A to 10E) and a housing (40) housing the submodules. The plurality of submodules (10A to10E) each include a group of cells (20) formed by arranging unit cells (22), and a binding member (30) applying binding pressure in an arrangement direction (X) of the plurality of unit cells. Inside the housing (40) of the battery module (1), there is an area which easily becomes relatively low temperature when the plurality of battery submodules (10A to 10E) are charged or discharged, and among the plurality of submodules (10A to 10E), the submodule (10A) disposed in the area which easily becomes low temperature has a lower binding pressure than the other submodules (10B to 10E).
여기에 개시되는 전지 모듈 (1) 은, 복수의 서브모듈 (10A ∼ 10E) 과, 서브모듈을 수용하는 하우징 (40) 을 갖는다. 상기 복수의 서브모듈 (10A ∼ 10E) 은, 단셀 (22) 이 나열된 셀군 (20) 과, 복수의 단셀의 배열 방향 (X) 으로 구속압을 작용시키는 구속 부재 (30) 를 각각 구비하고 있다. 그리고, 여기에 개시되는 전지 모듈 (1) 의 하우징 (40) 의 내부에는, 복수의 서브모듈 (10A ∼ 10E) 의 충방전을 실시했을 때에 상대적으로 저온이 되기 쉬운 영역이 있고, 복수의 서브모듈 (10A ∼ 10E) 중, 저온이 되기 쉬운 영역에 배치된 서브모듈 (10A) 은, 다른 서브모듈 (10B ∼ 10E) 보다 구속압이 낮다. |
