BATTERY MODULE AND COUPLING MEANS HAVING REINFORCING STRUCTURE FOR SWELLING OF BATTERY CELL

摘要

The present invention relates to a coupling means of a battery module to couple a plurality of battery cells with an end plate. The coupling means of the battery module comprises: a hook part hung at a penetration hole side of the end plate; and a head part separately arranged on an upper side of the hook part and to restrict the end plate not to move or be transformed in a height direction of the end plate in releasing the hanging state of the end plate and the hook part. According to the present invention, the coupling means has an effect of improving mechanical and electrical stability by allowing the coupling means to be transformed through a free space allowing transformation in swelling of a battery cell and by preventing a structure of the battery module from being damaged.
