Split Battery Module Container for Busbar Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The assembly of battery modules is hindered by the lack of operating space for connecting busbars when the distance between battery unit array structures is small, leading to reduced energy density due to the need for additional components for transportation.
Innovation Solution
A battery module design featuring split container bodies with separate accommodating cavities allows for sequential placement and fixation of battery units and connection to busbars without additional components, enhancing energy density by eliminating the need for extra transportation aids.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If battery units are first fixed and connected to busbars then transported to accommodating cavity, then assembly is simplified, but additional transportation components are required which reduces energy density
Solution Approach 1:
The patent merges the transportation function with the battery unit structure itself by designing the battery unit array structure to be directly placeable into the accommodating cavity. The battery units are arranged in a compact array that serves both as the functional battery assembly and as its own transportation载体, eliminating the need for separate transportation components and thereby improving energy density while maintaining assembly simplicity.
2Quantity of substance
If battery units are first accommodated and fixed then connected to busbars, then energy density is improved by eliminating transportation components, but operating space for busbar connection tools is insufficient when distance between battery unit array structures is small
Solution Approach 1:
The patent addresses the accessibility problem by designing the battery unit array structure with extended surfaces or protruding structures that bring the battery units closer to the busbars in the vertical or lateral dimension. This dimensional adjustment creates sufficient operating space for connection tools while maintaining the compact horizontal arrangement that ensures high energy density.
3Quantity of substance
If distance between battery unit array structures is reduced, then energy density is improved, but operating space for connection tools is eliminated making busbar connection extremely difficult
Solution Approach 1:
The patent introduces intermediary structures such as extended connection surfaces, protruding battery unit portions, or adjustable positioning mechanisms that act as mediators between the compact battery unit array and the busbars. These intermediaries provide the necessary access space for connection tools without increasing the overall distance between battery unit array structures, thus maintaining high energy density while reducing connection difficulty.

AI summary
The present disclosure relates to a battery module including a plurality of battery unit array structures and a battery container body. The battery container body includes a first container body and a second container body that are in a split structure. The first container body is disposed at a side of the second container body and provided with a first accommodating cavity. The second container body is provided with a second accommodating cavity. The plurality of battery unit array structures is disposed between the first container body and the second container body by means of a mutual cooperation of the first accommodating cavity and the second accommodating cavity. Compared with the related art, since the first or second container body is used for transportation, it is unnecessary to introduce an additional component, thereby enhancing the energy density of the battery module.
