Energy Storage Door Venting With Flame-Blocking Discharge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing energy storage systems lack an effective mechanism to mitigate damage from flames or gases released during battery ignition, posing a risk to the system and surrounding components.
Innovation Solution
A door system is designed with a door channel, inlet holes, and a discharge hole, along with a blocking member to prevent flames from passing through, while allowing gases to be discharged safely.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-generated harmful factors
If a door is designed with inlet holes to allow flame or gas discharge, then gas discharge capability is improved, but flame penetration risk increases
Solution Approach 1:
The door employs different structures for different regions: the blocking member with mesh structure is positioned at the discharge hole to block flames, while inlet holes remain open to allow gas discharge. This local differentiation resolves the contradiction by applying flame-blocking properties specifically where needed (discharge hole area) while maintaining gas discharge capability at inlet holes.
Solution Approach 2:
The blocking member acts as an intermediary element between the interior and exterior environments. It selectively allows gas to pass through while blocking flames, thus mediating the conflicting requirements of gas discharge and flame prevention. The mesh structure of the blocking member serves as the intermediate filter that permits gas flow but prevents flame propagation.
2Object-affected harmful factors
If a blocking member is added to prevent flame passage, then flame blocking capability is improved, but device complexity increases
Solution Approach 1:
The blocking member utilizes a mesh structure that functions as a porous material. This mesh configuration allows the blocking member to block flames while permitting gas to pass through the interstices. The porous/mesh structure achieves flame blocking without requiring a solid, completely sealed barrier, thus minimizing the increase in structural complexity.
3Productivity
If multiple inlet holes are provided for gas discharge, then gas discharge efficiency is improved, but flame introduction risk increases
Solution Approach 1:
The door channel is divided into multiple segmented inlet holes distributed at different positions. This segmentation allows gas to be discharged through multiple pathways, improving overall discharge efficiency. The segmented arrangement also reduces flame introduction risk by distributing the opening areas, making it less likely for a single flame source to penetrate through the door structure.

Function Achieved in This Case
The door system effectively reduces damage from flames by blocking their passage and directing gases for safe discharge, thereby protecting the energy storage system and adjacent components.

AI summary
A door for an energy storage system includes: a first door frame; a second door frame facing the first door frame; a door channel between the first door frame and the second door frame; an inlet hole passing through the first door frame and configured to allow a flame or gas to be introduced into the door channel; a discharge hole passing through the second door frame and configured to allow a flame or gas to be discharged from the door channel; and a blocking member facing the discharge hole and configured to block a flame that is discharged from the discharge hole from passing therethrough.
