Battery Pack Protective Components With Integrated Liquid Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing energy storage devices for motor vehicles require additional space and weight for superabsorbent materials to prevent liquid penetration, which compromises safety and efficiency.
Innovation Solution
Integrate superabsorbent materials into engineering plastics to form components within the energy storage device, allowing these components to perform additional functions without increasing weight or space, absorbing liquid only in exceptional cases.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If superabsorbent material is introduced as a separate component, then liquid absorption capability is improved, but device complexity and installation space increase
Solution Approach 1:
The superabsorbent material is combined with structural components (housing elements, protective covers, cable sheaths) to merge the absorption function with existing structural elements, eliminating the need for separate absorption components and reducing device complexity
Solution Approach 2:
Structural components are designed to serve multiple functions: providing mechanical support and protection while simultaneously containing superabsorbent material for liquid absorption, thereby reducing the number of separate components needed
2Reliability
If superabsorbent material is introduced as a separate component, then liquid absorption capability is improved, but weight increases
Solution Approach 1:
The superabsorbent material is integrated into existing structural components rather than being added as a separate element, so the weight of the absorption system is effectively included in the weight of necessary structural components, minimizing additional weight
3Reliability
If superabsorbent material is introduced as a separate component, then liquid absorption capability is improved, but installation space increases
Solution Approach 1:
The superabsorbent material is integrated into existing structural components such as housing elements and protective covers, utilizing already allocated space within the energy storage device structure, thereby avoiding additional installation space requirements
Solution Approach 2:
The superabsorbent material is nested within existing structural components (e.g., embedded in housing elements or protective covers), allowing the absorption function to be contained within the volume of necessary structural elements rather than requiring separate dedicated space

Implementation Method 1
superabsorbent materials, some of which are simply referred to below as super absorbers, are normally 'hard' plastic structures in the absence of water. Only when they come into contact with water do the super absorbers begin to swell and lose their mechanical stability.
Implementation Method 2
superabsorbent materials, some of which are simply referred to below as super absorbers, are normally 'hard' plastic structures in the absence of water. Only when they come into contact with water do the super absorbers begin to swell and lose their mechanical stability.

AI summary
An energy storage device for a motor vehicle with a protective device for protecting at least one battery cell of the energy storage device. The energy storage device includes at least one component made of a plastic material. The component is part of the protective device and the plastic material comprises a superabsorbent material, so that the at least one component is designed to absorb liquid. The component is also assigned an additional function that differs from the absorption of liquid.
