Integrated Busbar Protective Assembly for Battery Module Insulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery modules require two separate protective members for insulation protection of positive and negative busbars, leading to a large number of parts and low integration level.
Innovation Solution
A protective assembly with a protective member and two protective covers, where the protective member includes a body with high-voltage insulating seats to fix both positive and negative busbars, and the protective covers are detachably connected to enhance integration and reduce parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If two separate protective members are used for insulation protection of positive and negative busbars, then insulation protection is achieved, but the number of parts increases and integration level decreases
Solution Approach 1:
The patent combines two separate protective members into a single integrated protective assembly that simultaneously protects both the positive and negative busbars. The protective assembly includes a first protective member for the positive busbar and a second protective member for the negative busbar, merged into one unitary structure, thereby reducing the total number of parts while maintaining insulation protection for both busbars.
Solution Approach 2:
The protective assembly serves multiple functions within a single component: it provides insulation protection for both the positive and negative busbars, structural support for both busbars, and integration with both the cover plate and end plate. This multi-functional design eliminates the need for separate protective members while achieving comprehensive protection.
2Reliability
If two separate protective members are used for insulation protection, then protection coverage is complete, but manufacturing and assembly complexity increases
Solution Approach 1:
By merging the two protective members into one integrated protective assembly, the patent reduces assembly complexity from installing two separate components to installing a single component. The protective assembly is designed as one unit that can be manufactured and assembled more efficiently while providing complete protection coverage for both busbars.

AI summary
A protective assembly includes: a protective member and two protective covers. The protective member includes: a protective member body and two high-voltage insulating seats. The protective member body extends along a first direction and has first and second side faces opposite to each other along a second direction intersecting the first direction. The two high-voltage seats are respectively disposed at two ends of the first side face. One high-voltage insulating seat is configured to fix a positive busbar, and the other is configured to fix a negative busbar. The two protective covers are respectively covered on the two high-voltage insulating seats. The first side face is provided with a first connecting part configured to be connected to a cover plate of a battery module, and the second side face is provided with a second connecting part configured to be connected to an end plate of the battery module.
