Battery Tray with Insulative Elements for Electrical Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery energy storage systems lack effective electrical insulation between batteries and their trays, leading to potential electrical interference and safety risks.
Innovation Solution
Incorporating insulative elements between the battery and the tray members to ensure electrical isolation, using materials like ethylene propylene diene monomer (EPDM) rubber, Teflon, or plastic to prevent direct contact and electrical conduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the battery is directly supported by the tray members without insulative elements, then the structural support and ease of manufacture are improved, but electrical insulation and safety are worsened
Solution Approach 1:
The patent introduces insulative elements as intermediary components positioned between the battery and the tray members. These insulative elements serve as mediators that prevent direct electrical contact while maintaining the structural support function, thus resolving the contradiction between ease of manufacture and electrical insulation reliability
Solution Approach 2:
The tray structure is designed as a composite system combining conductive tray members (for structural support) with insulative elements (for electrical isolation). This composite approach allows the system to simultaneously achieve mechanical strength and electrical insulation properties
2Reliability
If insulative elements are added between the battery and tray members, then electrical insulation and safety are improved, but device complexity and manufacturing cost are worsened
Solution Approach 1:
The insulative elements are designed as thin film or shell structures that conform to the battery surface and tray member interfaces. This approach provides effective electrical insulation with minimal additional complexity, as the thin film nature allows for simple integration into the existing tray structure
Solution Approach 2:
The insulative elements are segmented into multiple discrete components positioned at specific contact points between the battery and tray members. This segmentation approach reduces overall complexity by only adding insulation where needed, rather than requiring complete insulation of the entire tray structure
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Achieves effective electrical insulation, reducing the risk of electrical interference and enhancing safety by ensuring no direct contact between the battery and the tray components.
Implementation Method 1
The insulative members can electrically isolate the battery from the first member, the second member, the tray, the frame of the cabinet, or the cabinet

AI summary
A battery tray can include a first member having a first lower portion and a first upper portion. The first lower portion can support a battery with a first insulative element positioned between the first lower portion and the battery. The first upper portion can couple with the battery with a second insulative element positioned between the battery and the first upper portion. The battery tray can include a second member having a second lower portion and a second upper portion. The second lower portion can support the battery with a third insulative element positioned between the second lower portion and the battery. The second upper portion can couple with the battery with a fourth insulative element positioned between the battery and the second upper portion.
