Battery Enclosure Layout for Higher Cell Packing Density
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in battery technology is to improve the energy density of batteries, particularly in electric vehicles, where energy conservation and emission reduction are crucial for sustainable development.
Innovation Solution
The solution involves designing a battery with a first box that has a non-closed side wall structure, allowing for increased space utilization by eliminating the draft angle interference with battery cells, thereby accommodating more cells or electronic components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the first box has a closed side wall structure with draft angle, then the structural strength is improved, but the enclosed space volume is reduced due to interference with battery cells
Solution Approach 1:
The patent removes the first side wall entirely, extracting the interfering structural element from the system. This allows the second box to directly connect to the bottom wall, eliminating the draft angle interference and maximizing the enclosed space volume for accommodating battery cells.
Solution Approach 2:
The patent changes the structural arrangement by removing the first side wall and allowing the second box to extend in a different spatial configuration. This dimensional reorganization eliminates the need for draft angle and optimizes the use of vertical space for battery cell accommodation.
2Quantity of substance
If the first side wall is removed to increase enclosed space, then the volume energy density is improved, but the structural strength may be reduced
Solution Approach 1:
The patent merges the first and second boxes by directly connecting the second box to the bottom wall without the intervening first side wall. This consolidation eliminates structural interference and maximizes the enclosed space volume, thereby increasing volume energy density while maintaining structural integrity through the integrated box design.
