Bus Bar Through-Hole Layout for Flexible Energy Storage Packaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing energy storage apparatus has a limited arrangement position for the bus bar due to its protrusion from the outer case, leading to difficulties in connecting the bus bar with external conductive members.
Innovation Solution
An energy storage apparatus with an outer case that includes a wall with a through hole, allowing the bus bar to penetrate and be arranged at a desired position, enhancing the degree of freedom in its placement while maintaining electrical connection and insulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the bus bar protrudes from between two members (case and cover member) forming the outer case, then the bus bar can be connected to external conductive members, but the arrangement position of the bus bar is restricted
Solution Approach 1:
The bus bar is configured to protrude from the side surface of the outer case rather than from the top surface between case and cover member. This dimensional change in protrusion location enables the bus bar to be arranged at various positions along the side surface, significantly improving arrangement position flexibility while maintaining connection capability to external conductive members.
2Reliability
If the bus bar protrudes from the outer case, then electrical connection is achieved, but insulation and structural integrity are compromised
Solution Approach 1:
An insulating member is introduced as an intermediary component that covers the bus bar at the protrusion position. This insulating member prevents direct contact between the conductive bus bar and the outer case or other conductive parts, thereby maintaining electrical insulation and structural integrity while allowing the bus bar to protrude for electrical connection.
3Ease of manufacture
If the bus bar is arranged with limited position options, then the outer case structure is simple, but connection difficulty increases
Solution Approach 1:
The outer case is designed with a through-hole in the side surface, separating the bus bar passage function from the main case structure. This segmentation allows the bus bar to pass through the through-hole and protrude from the side surface, enabling flexible arrangement positions without complicating the overall outer case manufacturing process.

AI summary
An energy storage apparatus includes an energy storage device, an outer case that accommodates the energy storage device and includes a wall in which a through hole is formed, and a bus bar penetrating the through hole.
