Integrated Battery Pack Fire-Fluid Storage for Compact Thermal Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current fire-fighting fluid storage apparatuses for battery packs occupy large spaces and have inconvenient spatial arrangements, which can lead to safety hazards during thermal failures in electric vehicles.
Innovation Solution
A compact fire-fighting fluid storage apparatus that integrates a liquid storage portion and a gas storage portion within a box, where the partition member is moved by compressed gas to drive the fire-fighting fluid towards an outlet, eliminating the need for additional monitoring and control systems, and allowing for efficient spraying without occupying excessive space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate liquid storage apparatus and gas storage apparatus are used, then the fire-fighting system can function properly, but the space occupation increases and spatial arrangement becomes inconvenient
Solution Approach 1:
The patent combines the liquid storage apparatus and gas storage apparatus into a single integrated storage device. The box contains both liquid storage and gas storage portions, with a partition member separating them. This merging eliminates the need for separate apparatus while maintaining the fire-fighting function, directly resolving the contradiction between system reliability and space occupation.
2Reliability
If separate liquid storage apparatus and gas storage apparatus are used, then the fire-fighting system can function properly, but the spatial arrangement becomes inconvenient
Solution Approach 1:
By integrating both liquid and gas storage functions into a single box structure, the patent simplifies the spatial arrangement within the battery pack. The unified design with internal partitioning makes installation and spatial planning more convenient compared to managing separate apparatus, while maintaining full fire-fighting functionality.
3Reliability
If traditional fire-fighting system is used, then fire protection is provided, but the structure becomes complex and occupies more space
Solution Approach 1:
The patent merges multiple components (liquid storage, gas storage, partition member, fluid inlet, fluid outlet) into a single integrated apparatus, reducing the overall system complexity while maintaining fire protection capability. This eliminates the need for separate liquid and gas storage apparatus, simplifying the overall system architecture.
Solution Approach 2:
The integrated box serves multiple functions simultaneously: it stores liquid fire-fighting fluid, stores compressed gas, provides structural support, and enables the spraying mechanism. This multi-functionality reduces the number of separate components needed, thereby reducing system complexity while maintaining comprehensive fire protection.

AI summary
The present application is provided with a fluid storage apparatus of a battery pack, including: a box, where the box has an inner cavity; a partition member, where the partition member is located in the inner cavity of the box, and the partition member divides the box into a fluid storage portion and a gas storage portion. The fluid storage portion is used to store spraying liquid and the fluid storage portion has a fluid outlet; the gas storage portion is used to store gas and the gas storage portion has a fluid inlet. And the partition member is configured to move toward the fluid outlet under the action of compressed gas in the gas storage portion.
