Battery Module Insulation Corner Fixing for Easier End Plate Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery modules face high assembly difficulty and poor assembly quality due to interference and warping of insulation members during assembly, leading to increased risks of short-circuiting and reduced structural stability.
Innovation Solution
A battery module design featuring an insulation member with corner regions fixedly connected to the battery group, using bonding members to stabilize the insulation member, and incorporating grooves to accommodate protrusions, thereby reducing warping and separation, and enhancing structural stability.

Engineering Contradiction Analysis
1Reliability
If an insulation member is arranged between the end plate and battery cells to improve safety, then short-circuiting risk is reduced, but the insulation member is prone to interference and impact during assembly causing high assembly difficulty and poor assembly quality
Solution Approach 1:
The insulation member is divided into a body portion and corner portions, where the corner portions are separately configured to be bonded to adjacent battery cells. This segmentation allows the corner portions to be independently positioned and fixed, reducing interference during assembly while maintaining the insulation function between the end plate and battery cells.
Solution Approach 2:
The corner portions of the insulation member are pre-configured with bonding structures that enable them to be bonded to the battery cells before final assembly. This preliminary preparation of bonding interfaces reduces assembly difficulty by eliminating the need for complex positioning and bonding operations during final assembly.
2Reliability
If an insulation member is arranged between the end plate and battery cells to improve safety, then short-circuiting risk is reduced, but the insulation member experiences warping or separation causing poor assembly quality
Solution Approach 1:
By dividing the insulation member into a body portion and separate corner portions, each component can be independently manufactured with precise dimensions and bonding interfaces. This segmentation enables better control over the geometric precision and bonding quality of each part, reducing warping and separation issues during assembly.
Solution Approach 2:
The corner portions are specifically designed with localized bonding structures and geometric features that match the battery cell corners. This local optimization ensures precise fitting and bonding at critical locations, preventing warping and separation while maintaining overall insulation effectiveness.

AI summary
A battery module, a battery, and a power-consuming apparatus are disclosed. The battery module includes a battery group, an end plate arranged on a side of the battery group in a first direction, and an insulation member positioned between the battery group and the end plate. An avoidance region is formed at a corner of the end plate, and a corresponding corner region of the insulation member is fixedly connected to the battery group. This configuration reduces warping or separation of the insulation member at the corner, enhances structural stability between the insulation member, end plate, and battery group, and minimizes interference with the end plate assembly region. As a result, the assembly difficulty of the battery module is lowered and the assembly quality is improved.
