Battery Rack Fire Suppressant Layout for Fast Thermal Event Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional battery racks face challenges in quickly and effectively controlling thermal events, which can lead to safety issues due to the wide-area spraying of fire extinguishing agents.
Innovation Solution
A battery rack design that includes a fire extinguishing agent supplier directly connected to the battery module, with a support structure to ensure stable positioning and efficient discharge of the extinguishing agent.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a water injection system sprays fire extinguishing agent over a wide area of the battery rack, then the coverage area is improved, but the effectiveness and speed of thermal event control deteriorates
Solution Approach 1:
The fire extinguishing agent supplier is positioned to face the battery module directly, concentrating the fire extinguishing agent discharge onto the specific location where thermal events occur rather than spraying widely. This localized discharge approach improves thermal event control effectiveness while maintaining adequate coverage of the critical battery module area
2Area of stationary object
If a water injection system sprays fire extinguishing agent over a wide area, then the coverage is improved, but the response speed to thermal events deteriorates
Solution Approach 1:
By positioning the fire extinguishing agent supplier to face the battery module and discharge the agent locally onto the thermal event source, the system achieves faster response speed. The concentrated discharge path reduces the time required to reach and suppress thermal events compared to wide-area spraying methods
3Reliability
If the fire extinguishing agent supplier is directly connected to the battery module with stable positioning, then the thermal event control effectiveness is improved, but the device complexity increases
Solution Approach 1:
The support structure integrates multiple functions: it positions the fire extinguishing agent supplier, provides structural stability, and ensures proper orientation toward the battery module. By combining these functions into a single integrated support structure rather than separate components, the design improves thermal event control effectiveness while minimizing the increase in device complexity
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
This configuration allows for direct and targeted discharge of the fire extinguishing agent onto the battery module, effectively suppressing thermal events quickly and maintaining stability even under strong vibrations.
Implementation Method 1
a fire extinguishing agent supplier disposed on a first side of the rack frame and connected to the at least one battery module

AI summary
A battery rack controls thermal events. An electric power storage system includes the battery rack. A battery rack includes a battery module, a rack frame configured to accommodate the battery module, a fire extinguishing agent supply module disposed on one side of the rack frame and connected to the battery module, and a support module coupled to the one side of the rack frame and configured to support the fire extinguishing agent supply module such that the fire extinguishing agent supply module faces the battery module.
