The invention relates to a battery module having a plurality of prismatic battery cells (2, 20), which are arranged next to one another in a longitudinal direction (4) of the battery module (1) and furthermore are braced with one another, wherein the plurality of battery cells (2) are received in an interior (30) of a housing (3) of the battery module (1) and additionally a bottom surface (31) of the housing (3) of the battery module (1) and a bottom surface (21) of the battery cells (2) are respectively cohesively connected to one another, wherein a compressing element (11) is arranged between the housing (3) and the plurality of battery cells (2) in the longitudinal direction (4) of the battery module (1), which compressing element tapers perpendicularly to the longitudinal direction (4) of the battery module (1) in the direction of the bottom surface (31) of the housing (3).
A battery module having a plurality of prismatic battery cells (2, 2), which are arranged next to one another in a longitudinal direction (4) of the battery module (1) and furthermore are braced with one another, wherein the plurality of prismatic battery cells (2) are received in an interior (30) of a housing (3) of the battery module (1) and additionally a bottom surface (31) of the housing (3) of the battery module (1) and a bottom surface (21) of the plurality of prismatic battery cells (2) are respectively cohesively connected to one another, wherein a first compressing element (11) and a second compressing element (11) are each arranged between the housing (3) and a single end-most prismatic battery cell (2) of the plurality of prismatic battery cells (2) on a same longitudinal end of the battery module (1), wherein the first compressing element and the second compressing element each taper perpendicularly to a longitudinal direction (4) of the battery module (1) in a direction of the bottom surface (31) of the housing (3), and wherein the first and second compressing elements (11) are separated from one another to provide an air gap therebetween in a direction perpendicular to the longitudinal direction and therefore also creating an air gap between the housing (3) and the single end-most prismatic battery cell (2) adjacent the first and second compressing elements (11), the first and second compressing elements (11) further being independently insertable into the battery module such that the first and second compressing elements can be inserted into the housing (3) to different extents.
A battery module having a plurality of prismatic lithium-ion battery cells (200), which are arranged next to one another in a longitudinal direction (4) of the battery module (1) and furthermore are braced with one another, wherein the plurality of prismatic lithium-ion battery cells (2) are received in an interior (30) of a housing (3) of the battery module (1) and additionally a bottom surface (31) of the housing (3) of the battery module (1) and a bottom surface (21) of the plurality of prismatic lithium-ion battery cells (2) are respectively cohesively connected to one another by means of an adhesive, wherein a first compressing element (11) and a second compressing element (11) are each arranged between the housing (3) and a single end-most prismatic lithium-ion battery cell (2) of the plurality of prismatic lithium-ion battery cells (2) on a same longitudinal end of the battery module (1), wherein the first compressing element and the second compressing element each taper perpendicularly to a longitudinal direction (4) of the battery module (1) in a direction of the bottom surface (31) of the housing (3), and wherein the first and second compressing elements (11) are separated from one another to provide an air gap therebetween in a direction perpendicular to the longitudinal direction and therefore also creating an air gap between the housing (3) and the single end-most prismatic lithium-ion battery cell (2) adjacent the first and second compressing elements (11), the first and second compressing elements (11) further being independently insertable into the battery module such that the first and second compressing elements can be inserted into the housing (3) to different extents.
