Battery Module Busbar Support Assembly for Reliable Cover Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly of protection covers and busbar supports in battery modules is inconvenient and unreliable, particularly when the protection cover is mounted at the side of the battery module, leading to difficulties in ensuring assembly reliability.
Innovation Solution
A battery module design that includes a busbar support with first and second mounting portions and a protection cover with third and fourth mounting portions, allowing for engagement between these to facilitate a simple and reliable assembly process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the protection cover is mounted at the side of the battery module corresponding to the busbar support, then the protection cover can be assembled, but the assembly process becomes inconvenient and assembly reliability is difficult to ensure
Solution Approach 1:
The busbar support is divided into two separate mounting portions: a first mounting portion for mounting the protection cover and a second mounting portion for mounting the battery module. This segmentation allows the protection cover to be mounted independently on the busbar support before the battery module is installed, eliminating the inconvenience of side mounting and ensuring reliable assembly through dedicated mounting interfaces.
2Adaptability or versatility
If the protection cover and busbar support are mounted at the side of the battery module, then both components can be installed, but it is difficult to ensure assembly reliability
Solution Approach 1:
The protection cover is pre-mounted on the busbar support through the first mounting portion before the battery module is installed. This preliminary action ensures that the protection cover is securely positioned and aligned, making the subsequent assembly of the battery module straightforward and reliable, rather than attempting to assemble both components simultaneously at the side of the battery module.

AI summary
Provided are a battery module (100), a battery pack, and a vehicle. The battery module (100) includes battery cells (1), a busbar (2), a busbar support (3), and a protection cover (4). The busbar (2) is configured to electrically connect two battery cells (1) and limit a position of the busbar support (3) at the battery cells (1). The busbar support (3) has a first mounting portion (31) and a second mounting portion (32). The protection cover (4) is located at a side of the busbar support (3) away from the plurality of battery cells (1). The protection cover (4) has a third mounting portion (41) and a fourth mounting portion (42). The protection cover (4) is fixed to the busbar support (3) by engaging the first mounting portion (31) and the second mounting portion (32) with the third mounting portion (41) and the fourth mounting portion (42), respectively.
