Description

本発明の電池モジュールは、熱伝導部材を介して筐体に取り付けられる電池モジュールであって、一方向に配列される複数の電池セルと、電池セルの一方向に交差する面である主面に接触するように配置されて一方向に配列される複数の伝熱プレートと、を有する配列体と、配列体を一方向に加圧した状態で拘束する拘束部と、を備え、伝熱プレートは、主面に接触する第一本体部と、第一本体部の一端部から主面に交差する方向に折れ曲がり、熱伝導部材に接触する第二本体部と、を有し、第二本体部における一端部とは反対側の他端部と、第一本体部から第二本体部が折れ曲がる方向に隣接して配置されている伝熱プレートとが、電池セルの膨張により伝熱プレートが移動する前の状態において、電池セルの膨張による伝熱プレートの一方向における移動量に応じた距離離れている。 The battery module of the present invention is a battery module that is attached to a housing via a heat conducting member, and has a plurality of battery cells arranged in one direction and a main surface that intersects the battery cell in one direction. A plurality of heat transfer plates arranged so as to be in contact with each other and arranged in one direction; and a restraining portion that restrains the array in a state of being pressed in one direction. A first main body portion that contacts the main surface, and a second main body portion that bends in a direction intersecting the main surface from one end of the first main body portion, and contacts the heat conducting member. Before the heat transfer plate moves due to the expansion of the battery cell , the other end opposite to the one end and the heat transfer plate disposed adjacent to the first main body in the direction in which the second main body is bent. in the state, one heat transfer plate according to the expansion of the battery cells Apart a distance corresponding to the movement amount in the direction.

Claims
