Battery Module Cover Conduit for Early Cell Fire Suppression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fire extinguishing systems for battery modules are inefficient in suppressing high-pressure fires at an early stage and can damage conduits during transportation and handling.
Innovation Solution
A battery module with a conduit integrated into the cover, designed to be fixed and protected during handling, and an energy storage system with a flexible supply pipe system delivering fire-extinguishing chemicals directly to the affected battery cells.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate conduit system is used for fire extinguishing, then fire suppression capability is provided, but the conduit is damaged during transportation and handling
Solution Approach 1:
The conduit is integrated into the cover structure, forming a unified component. The cover serves dual functions: protecting the battery cells and housing the fire extinguishing conduit. This merging eliminates the separate conduit system that was vulnerable to damage during handling, while maintaining fire suppression capability through the integrated conduit that delivers extinguishing agent directly to battery cells.
2Reliability
If existing fire extinguishing systems are used, then fire suppression is provided, but they are inefficient in suppressing high-pressure fires at an early stage
Solution Approach 1:
The conduit is pre-positioned within the cover at locations that correspond to the vent positions of battery cells. This preliminary positioning ensures that when a fire occurs, the extinguishing agent can be delivered immediately and directly to the affected battery cell through the pre-established conduit pathway, enabling rapid response to high-pressure fires at their earliest stage without delay for system activation or agent delivery.
