Battery module and power-consuming device

Abstract

Battery module, characterized in that the battery module comprises: several pouch cells (10), wherein the several pouch cells (10) are arranged in a first direction, wherein the pouch cell (10) comprises a housing (11) and a cell core arranged in the housing (11), wherein the housing (11) has two large surfaces (111) having the largest area and arranged opposite each other, and a side surface (112) connected to the large surfaces (111), wherein the side surface (112) extends perpendicular to the large surfaces (111) and the first direction extends perpendicular to the large surfaces (111), wherein the housing (11) comprises a first insulating layer, a metal layer and a second insulating layer arranged stacked on top of each other; a heat exchanger plate (60) which is arranged opposite the side surface (112) and is thermally connected to it;a metallic heat-conducting plate (40), wherein the metallic heat-conducting plate (40) is arranged between at least two pouch cells (10) arranged in the first direction, wherein the metallic heat-conducting plate (40) is thermally connected to the heat exchange plate (60); wherein the thickness of the metallic heat-conducting plate (40) is Amm, wherein the ratio of the thickness of the metal layer to the thickness of the housing (11) is B, wherein the relationship between the thickness Amm of the metallic heat-conducting plate (40) and the ratio B is: 0.8 ≤ A / B ≤ 20.0.;
