AI Technical Summary

Technical Problem

Existing battery modules lack sufficient impact resistance when subjected to external excessive impacts, such as those encountered in vehicle applications, which can lead to damage and displacement of battery cells.

Method used

A battery module design featuring a duct system integrated with an attachment-target member forms a beam structure that extends in the stacking direction, providing enhanced impact resistance by distributing impacts evenly and preventing battery cells from jumping out, with specific wall configurations and thicknesses to increase rigidity and secure attachment.

Benefits of technology

The design significantly improves impact resistance and prevents battery cell displacement, ensuring the module's structural integrity and performance under external impacts, particularly in vehicle-mounted applications.

Abstract

A battery module includes: a duct (71) extending in a Y axis direction in which a plurality of battery cells (11) are stacked, to form a flow space (110) for gas; and an attachment-target member (30) to which the duct (71) is attached. The attachment-target member (30) has a first wall portion (111) and a pair of second wall portions (116) each rising from the first wall portion (111) in a Z axis direction, the pair of second wall portions (116) being provided with a space being interposed therebetween in an X axis direction. The duct (71) is disposed between the pair of second wall portions (116). The duct (71) has: a third wall portion (136) facing the first wall portion (111) in the Z axis direction with the flow space (110) being interposed therebetween; and a pair of fourth wall portions (131) extending, in the Z axis direction toward the first wall portion (111), from both end portions of the third wall portion (136) in the X axis direction, the pair of fourth wall portions (131) respectively facing the pair of second wall portions (116) in the X axis direction.
