Battery Pack Beam-Mounted Electrical Support Base
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The limited energy density and space utilization in electric car batteries result in shorter battery life, as most electrical support bases are placed at the end plate of the battery module, occupying space and preventing maximum battery accommodation.
Innovation Solution
A battery pack design featuring a box body with a beam that forms compartments, where the battery apparatus is placed, and an electrical support base is positioned on the beam, allowing the electrical conductor to extend and connect directly, thereby saving space and enabling more batteries to be accommodated.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electrical support bases are arranged at the end plate of the battery module, then electrical connection is achieved, but space in the battery module is occupied and the number of batteries that can be accommodated is reduced
Solution Approach 1:
The patent relocates the electrical support base from the traditional end plate position (one-dimensional arrangement) to the beam structure (three-dimensional spatial redistribution). This dimensional shift allows the support base to be positioned above the battery modules rather than at the end, freeing up end plate space for additional battery accommodation while maintaining electrical connection functionality through the beam-mounted support base.
2Quantity of substance
If more batteries are arranged in the accommodating compartments, then energy density increases, but space for electrical support bases and other devices is reduced
Solution Approach 1:
The patent merges the functions of the beam structure by making it serve dual purposes: providing structural support for the battery modules and mounting the electrical support base. This consolidation of functions eliminates the need for separate end plate space for electrical components, allowing maximum battery accommodation while maintaining all necessary electrical infrastructure through the integrated beam support system.
