Battery Module Auto-Release Rack for Fire Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ESS systems face significant challenges in containing and extinguishing fires within battery modules, as a fire in one battery can spread to surrounding modules due to their interconnected structure, making rapid isolation and extinguishment difficult.
Innovation Solution
A system and method for automatically releasing a battery module by inclining the module installation structure, using a module fixing device to detach modules from the rack under control of a battery control unit, and employing an extinguishment agent spray device to isolate and extinguish the affected modules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If battery modules are stacked in a rack structure to construct an ESS system, then energy storage capacity is improved, but fire spread risk increases when a battery module catches fire
Solution Approach 1:
The battery rack is divided into multiple independent compartments or sections. When a fire is detected in one battery module, the partitioning mechanism isolates the affected module from adjacent modules, preventing fire spread while maintaining the overall energy storage capacity of the system.
Solution Approach 2:
The affected battery module is automatically extracted or removed from the rack structure when fire is detected. This extraction isolates the fire source from other modules, preventing fire spread while preserving the functionality of remaining modules.
2Stability of the object's composition
If battery modules are fixed securely in the rack, then system stability is improved, but rapid release and isolation capability deteriorates when fire occurs
Solution Approach 1:
The fixing mechanism transitions from a static secured state to a dynamic release state when fire is detected. The system maintains stable fixation during normal operation but can rapidly transition to release mode, enabling both system stability and quick isolation when needed.
Solution Approach 2:
The fixing mechanism automatically releases the affected battery module without external intervention when fire conditions are detected. The system self-activates the release function, combining secure fixation during normal operation with automatic rapid release during emergencies.
3Reliability
If extinguishment material is sprayed to extinguish fire, then fire suppression capability is improved, but effectiveness deteriorates when fire has already spread to surrounding modules
Solution Approach 1:
The system performs preliminary isolation of the affected battery module before fire spread occurs. By separating the fire source from adjacent modules in advance, the system creates containment zones that enable more effective and localized fire suppression, preventing catastrophic spread.
Solution Approach 2:
The fire suppression system is divided into localized zones corresponding to individual battery modules or rack sections. When fire is detected, only the affected zone is isolated and targeted for suppression, concentrating extinguishment resources where needed most effectively while preventing spread to other zones.

Function Achieved in This Case
Minimizes damage by rapidly isolating and extinguishing individual battery modules, preventing the spread of fire to adjacent modules and reducing overall system damage.
Implementation Method 1
Connection parts of the battery module and the battery rack are magnetically connected.
Implementation Method 2
The battery module is fixed on a module installation structure incline of the battery rack by a module fixing device, and is released from the battery rack along the module installation structure incline as the module fixing device is operated

AI summary
Disclosed are a system and method for automatically releasing a battery module, and more particularly, to a system and method for automatically selectively releasing a battery module from the entire structure when a high temperature or the generation of heat is detected in a module unit stack structure. The system includes a battery module including at least one battery cell, a battery rack in which the battery module is held, and a battery control unit configured to perform control to automatically release the battery module from the battery rack. The battery module is fixed on a module installation structure incline of the battery rack by a module fixing device, and is released from the battery rack along the module installation structure incline as the module fixing device is operated under the control of the battery control unit when an issue occurs in the battery module.
