[0002] With the development of new energy technology, the demand for battery modules is increasing. Packaging structure is a key technology in the field of energy storage. Since the battery cell will produce gas during the charge and discharge cycle, the battery cell will expand. In order to solve the problem of battery cell expansion force during module packaging, the relevant technology uses end plates and steel belts to ensure that the module dimensions are not affected, and then assemble them into a tray to form a PACK. However, the steel belt is used to wrap the battery module assembly and installation efficiency is low, and it takes a lot of time to wind the module, which increases the cost. When the number of battery modules increases, the weight of the battery module increases accordingly. Since there is no support device at the bottom of the battery module, the restraining force of the steel belt is limited, which will cause the battery module to spread out and cause the packaging structure of the battery module to fail.

[0003] Therefore, it is necessary to provide a packaging structure that can solve the problems of low battery module installation efficiency and limited battery module size. Utility Model Content
