Abstract

The invention provides a packaging shell. The packaging shell comprises a first end plate and a second end plate opposite to the first end plate, and a first side palte and a second side plate arranged opposite to the first side plate. The first side plate and the second side plate are arranged between the first end plate and the second end plate. A first through hole is formed in the first end plate, and a convex body penetrating through the first through hole is arranged on the first side plate. The packaging shell further comprises a fixing piece, and the fixing piece detachably fixes the first end plate and the first side plate or the second side plate. The invention also provides a battery pack. The invention aims to at least solve the problem of difficult assembly of the soft packagelithium battery module under the condition of narrow assembly space so as to improve the assembly convenience of the soft package lithium battery module.

Description

Technical field [0001] This application relates to the field of energy storage, and more specifically, to a packaging shell and a battery pack. Background technique [0002] In the related art, the battery pack (battery module) mainly adopts the following three structures. [0003] The first structure is to use a battery cell bracket to support the battery cell, and lock all the battery cells together by a long screw or a steel tie to form a battery module. The disadvantage of this structure is that the cost of the module is relatively high, and when the assembly space of the module is very small, the cell support structure can only be designed very weakly, which makes it difficult to effectively support the cell. [0004] The second structure is to press all the cells together through two upper and lower end plates, and use screws to lock the cells and end plates to form a battery module. The disadvantage of this structure is that the module has excessive locking pressure or exces...
