Energy Storage Domain Controller for Thermal Runaway Response
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing energy storage systems face challenges in managing battery health, safety, and operational efficiency, particularly in preventing thermal runaway and optimizing the operation of heat management and fire-fighting units.
Innovation Solution
A domain controller is integrated into the energy storage system, combining energy storage unit management and non-energy storage unit management modules. This centralized control enables smooth and fast information exchange between modules, improving system management efficiency and allowing for timely adjustments to the operating states of both energy storage and non-energy storage units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the energy storage unit management module and non-energy storage unit management module are arranged in a decentralized manner, then the system structure is simpler, but the information exchange between modules is slow and system management efficiency is reduced
Solution Approach 1:
The patent merges the energy storage unit management module and non-energy storage unit management module into a single domain controller. This integration enables centralized control, improves information exchange speed between modules, and enhances overall system management efficiency while maintaining manageable system complexity through modular internal architecture.
2Reliability
If the fire-fighting unit management module is separate from the energy storage unit management module, then the system is easier to maintain, but the fire-fighting unit cannot acquire state information in time to ensure security
Solution Approach 1:
The fire-fighting unit management module is integrated into the domain controller alongside the energy storage unit management module. This unified structure enables real-time sharing of state information between modules, allowing the fire-fighting unit to immediately respond to thermal runaway risks while maintaining system security. The integrated design preserves ease of maintenance through standardized interfaces and modular components.
3Adaptability or versatility
If the non-energy storage unit operates independently without integration, then the operating cost is lower, but the operating state cannot be adjusted according to actual operation demands
Solution Approach 1:
The integrated domain controller implements feedback mechanisms where the non-energy storage unit (heat management and fire-fighting units) receives real-time state information from the energy storage unit. Based on this feedback, the system dynamically adjusts the operating state of non-energy storage units according to actual operation demands, optimizing performance while managing operational costs through intelligent control rather than continuous full-power operation.
