要約
(EN) In order to protect a heat-shrinkable film that covers a battery cell even if the battery cell is used in a state where the battery cell repeatedly expands and contracts, this power source device comprises: a plurality of battery cells (1) each having an outer can (11) which is quadrangular, with primary surfaces (1A) opposing each other; an insulative heat-shrinkable film (5) that covers each of the plurality of battery cells (1); a plurality of separators (2) that are interposed between the plurality of battery cells (1); a battery layered body obtained by layering the plurality of battery cells (1) with the separators (2) therebetween; a pair of end plates disposed at both end surfaces of the battery layered body; and a plurality of binding bars that are disposed at opposing side surfaces of the battery layered body, and that fasten the end plates together. The heat-shrinkable film (5) has expandability such that a maximum elongation amount of the film in a heat-shrunken state is greater than a maximum elongation amount of the primary surface (1A) of the outer can (11) during expansion of the battery cell (1).
(FR) L'invention a pour objet de protéger un film thermorétractable revêtant des cellules de batterie, y compris dans le cas d'une mise en œuvre dans un état de répétition de dilatation et de rétractation des cellules de batterie. À cet effet, l'invention concerne un dispositif d'alimentation électrique qui est équipé : d'une pluralité de cellules de batterie (1) présentant un boîtier externe (11) carré, et possédant des faces principales (1A) en opposition ; du film thermorétractable (5) isolant revêtant individuellement la pluralité de cellules de batterie (1) ; d'une pluralité de séparateurs (2) s'intercalant entre les cellules de batterie (1) ; d'un empilement de batterie formé par empilement des la pluralité de cellules de batterie (1) avec les séparateurs (2) pour intermédiaire ; d'une paire de fonds de capot disposée sur les deux faces extrémité de l'empilement de batterie ; et d'une pluralité de barres de liaison disposée individuellement sur des faces latérales s'opposant à l'empilement de batterie, et serrant les fonds de capot entre eux. Le film thermorétractable (5) présente un allongement maximal, à l'état de thermorétraction, supérieur à l'allongement maximal des faces principales (1A) du boîtier externe (11) lors de la dilatation des cellules de batterie (1).
(JA) 電池セルが膨張と収縮を繰り返す状態で使用されても、電池セルを被覆する熱収縮性フィルムを保護するために、電源装置は、外装缶(11)を角形とし、対向する主面(1A)を有する複数の電池セル(1)と、複数の電池セル(1)をそれぞれ被覆する絶縁性の熱収縮性フィルム(5)と、複数の電池セル(1)同士の間に介在される複数のセパレータ(2)と、複数の電池セル(1)をセパレータ(2)を介して積層してなる電池積層体と、電池積層体の両端面に配置された一対のエンドプレートと、電池積層体の対向する側面にそれぞれ配置されて、エンドプレート同士を締結する複数のバインドバーとを備える電源装置であって、熱収縮性フィルム(5)は、熱収縮された状態での最大伸び量が、電池セル(1)の膨張時における外装缶(11)の主面(1A)の最大伸び量よりも大きくなる伸縮性を有している。
