Abstract
(EN)
A battery module, comprising a first battery module (1), a second battery module (2), and a cooling plate (3), and a plurality of busbars (12) electrically connected to a plurality of battery units (11). Each battery unit (11) is laid flat in the battery module such that, when having a coiled structure, an electrode assembly (111) is a flat shape, and the outer surface of the electrode assembly (111) comprises two flat surfaces (1110), the two flat surfaces (1110) facing one another in the vertical direction; and, when the electrode assembly (111) has a stacked structure, a first electrode plate (1111), a diaphragm (1113), and a second electrode plate (1112) are stacked in the vertical direction. In addition, as the cooling plate (3) is placed between the first battery module (1) and the second battery module (2), and the two surfaces of the cooling plate (3) are respectively attached to the first battery module (1) and the second battery module (2) by means of thermally conductive adhesive (4), the first battery module (1) and the second battery module (2) can be mounted very close to the cooling plate (3), increasing the heat dissipation area and thereby improving the heat dissipation effect.
(FR)
Module de batterie, comprenant un premier module de batterie (1), un second module de batterie (2), et une plaque de refroidissement (3), et une pluralité de barres omnibus (12) électriquement connectées à une pluralité d'unités de batterie (11). Chaque unité de batterie (11) est posée à plat dans le module de batterie de telle sorte que, lorsqu'elle présente une structure bobinée, un ensemble électrode (111) est une forme plate, et la surface extérieure de l'ensemble électrode (111) comprend deux surfaces plates (1110), les deux surfaces plates (1110) se faisant face dans la direction verticale ; et, lorsque l'ensemble électrode (111) présente une structure empilée, une première plaque d'électrode (1111), un diaphragme (1113) et une seconde plaque d'électrode (1112) sont empilés dans la direction verticale. De plus, étant donné que la plaque de refroidissement (3) est placée entre le premier module de batterie (1) et le second module de batterie (2), et que les deux surfaces de la plaque de refroidissement (3) sont respectivement fixées au premier module de batterie (1) et au second module de batterie (2) au moyen d'un adhésif thermoconducteur (4), le premier module de batterie (1) et le second module de batterie (2) peuvent être montés très près de la plaque de refroidissement (3), augmentant la zone de dissipation de chaleur et améliorant ainsi l'effet de dissipation de chaleur.

一种电池模组,包括第一电池模块(1)、第二电池模块(2)以及冷却板(3),以及与所述多个电池单体(11)电连接的多个汇流排(12)。在电池模块中的每个电池单体(11)平躺放置,即当电极组件(111)为卷绕式结构时为扁平状,电极组件(111)的外表面包括两个扁平面(1110),两个扁平面(1110)沿竖直方向相互面对;当电极组件(111)为叠片式结构时,第一极片(1111)、隔膜(1113)和第二极片(1112)沿竖直方向层叠。另外,由于冷却板(3)放置于第一电池模块(1)与第二电池模块(2)之间,并且冷却板(3)的两个表面分别通过导热胶(4)粘接于第一电池模块(1)和第二电池模块(2),使得第一电池模块(1)与第二电池模块(2)能够紧贴冷却板(3)安装,增加了散热面积,从而提高了散热效果。
