Problems solved by technology

[0002] The manufacturing method of the non-integrated frame structure of the existing technology modules, the strength and rigidity of the modules are insufficient, the length of the long modules is limited, the reliability of the electrical connection between the cells is low, and the long connecting rods pass through Each battery cell is continuously subjected to compressive stress, which affects the life and safety of each battery cell
At the same time, when cutting a long module, the components such as the battery core that pass through the long module are often damaged by cutting or damaged by the heat generated during the cutting process.

Abstract

The invention discloses a protection plate and a long module cutting method, which relate to the field of batteries. The protection plate is used for cutting a long module formed by sequentially connecting a plurality of sub-modules in series through a module partition plate, and the module partition plate is provided with a plurality of cavities penetrating from the top end face to the bottom endface and comprises a flat plate and a plurality of columnar plug pins; the side wall of the flat plate is connected with the end faces of the multiple columnar plug pins in a welded mode, and the columnar plug pins are inserted into the cavities of the module partition plate during cutting. The cutting tool is separated from the elements in the long module through the protection plate, and the elements of the long module are prevented from being damaged in the cutting process.

Description

technical field [0001] The invention relates to the field of batteries, in particular to a method for cutting a protective plate and a long module. Background technique [0002] The manufacturing method of the non-integrated frame structure of the existing technology modules, the strength and rigidity of the modules are insufficient, the length of the long modules is limited, the reliability of the electrical connection between the cells is low, and the long connecting rods pass through Each battery cell is continuously subjected to compressive stress, which affects the life and safety of each battery cell. At the same time, when cutting a long module, the components such as the battery cells passed through the long module are often damaged by cutting or due to the heat generated during the cutting process. Contents of the invention [0003] In view of the defects existing in the prior art, the purpose of the present invention is to provide a protective plate and a cuttin...
