Energy Storage Container Fire-Fighting Layout Without Equipment Compartment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The integration of components in a 20-foot 5 MWh liquid-cooled energy storage container exceeds standard sizes due to the need for a large-scale fire-fighting device, necessitating an additional equipment compartment, which complicates space optimization.
Innovation Solution
A miniaturized fire-fighting system is dispersed among battery clusters and the top cover, eliminating the need for a separate compartment and optimizing space utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a large-scale fire-fighting device is used, then fire-fighting capability is improved, but space utilization deteriorates due to the need for an independent equipment compartment
Solution Approach 1:
The patent divides the single large-scale fire-fighting device into multiple smaller fire-fighting devices. Specifically, it uses four 9L fire-fighting devices instead of one large device, allowing them to be dispersedly arranged in the container without requiring a dedicated equipment compartment. This segmentation maintains adequate fire-fighting capability while significantly improving space utilization.
Solution Approach 2:
The patent changes the arrangement dimension by dispersing fire-fighting devices throughout the container volume rather than concentrating them in a single location. The devices are positioned at different heights and locations (including near the top cover and among battery clusters), utilizing three-dimensional space efficiently and eliminating the need for a separate equipment compartment.
2Ease of manufacture
If a separate equipment compartment is provided, then fire-fighting device placement is simplified, but container length direction space is wasted
Solution Approach 1:
The patent merges the fire-fighting system with the battery cluster arrangement by placing fire-fighting devices among the battery clusters rather than in a separate compartment. This integration allows the fire-fighting devices to share the same space as the battery modules, eliminating the need for additional length in the container and achieving more compact overall dimensions.
3Volume of stationary object
If fire-fighting devices are dispersed among battery clusters, then space utilization is improved, but device complexity increases
Solution Approach 1:
The patent employs standardized 9L fire-fighting devices that can be universally installed in multiple locations throughout the container. These identical devices serve the same fire-fighting function regardless of their position, simplifying the overall system design despite the dispersed arrangement. The uniformity of the devices reduces complexity compared to using different types of fire-fighting equipment in various locations.

AI summary
The present application provides an energy storage container including a container body, battery clusters, and a fire-fighting system. The container body includes a top cover and a bottom cover oppositely disposed. The container body is provided with a battery compartment, and the top cover and the bottom cover surround a top portion and a bottom portion of the battery compartment, respectively. The battery clusters are disposed in the battery compartment. The fire-fighting system includes fire-fighting devices uniformly dispersedly arranged among the battery clusters and the top cover.
