WIPO Patent Application WO/2023/146272

A1

The present invention provides a battery module comprising: a battery cell assembly (100) including a reference plate (110) having a predetermined thickness in a third direction, a first stacking portion (120) comprising a plurality of battery cells (C ) that are respectively coupled to one side and the other side of the reference plate (110) in the third direction and mutually stacked on one another in the third direction to be coupled, and a second stacking portion (130); and a frame (200) having an inner space (S) in which the battery cell assembly (100) is inserted and accommodated. The inner space (S) includes a predetermined portion (P1) in which the reference plate (110) is accommodated and a one side portion (P2) and the other side portion (P3), which respectively correspond to one space and the other space of the predetermined portion (P1) in the third direction, with respect to the predetermined portion (P1), and in which the first stacking portion (120) and the second stacking portion (130) are accommodated, respectively. The location of the predetermined portion (P1) is determined based on the lengths of the first stacked portion (120) and the second stacked portion (130) in the third direction. Thus, a battery module (10) with improved safety and reliability may be easily and quickly manufactured at low cost with a simple configuration.
