In-Depth Analysis of Thermal Runaway Early Warning and Response Mechanisms for Industrial Panel PCs Under New Energy Storage Safety Standards
Driven by the dual imperatives of the "dual carbon" strategy and energy security, the energy storage industry is poised for explosive growth by 2025. However, frequent thermal runaway incidents have emerged as a critical bottleneck to sustainable development. The implementation of China's mandatory standard GB 44240-2025 elevates energy storage safety from post-incident firefighting to proactive prevention, mandating that thermal runaway events must not propagate, produce external flames, or cause enclosure rupture within 24 hours at the system level. In this context, industrial panel PCs—serving as the "nervous system" of energy storage systems—have become pivotal for safety assurance through their thermal runaway early warning and rapid response capabilities.
Technical Challenges Under New Standards: Paradigm Shift from Passive Response to Proactive Prevention
1.1 Stringent Testing Standards Driving Technological Upgrades
GB 44240-2025 introduces 23 extreme testing protocols including vibration, accelerated impact, shallow puncture, and forced discharge to simulate real-world operational extremes during transportation, installation, and operation. For instance, during forced discharge testing, systems must sustain 3C-rate continuous discharge from 90% state of charge (SOC) to voltage protection limits, demanding unprecedented precision in battery management system (BMS) data acquisition and controller response speeds.
1.2 Full Lifecycle Safety Closed-Loop Requirements
The new standard establishes a comprehensive safety chain spanning design, manufacturing, operation, maintenance, and recycling. A photovoltaic energy storage project utilizing USR-EG628 industrial computers demonstrates this approach: through edge computing capabilities, the system monitors 1,200 data points in real-time during battery charge/discharge cycles, constructing digital twin models based on historical charge-discharge curves to enable full lifecycle safety management from cell to system level.
1.3 Necessity of Multi-Parameter Fusion Early Warning
Traditional single-parameter warning systems exhibit significant limitations: temperature sensor response delays reach minutes, gas sensors require temperatures above 200°C, while early-stage thermal runaway only elevates cell temperatures by 10-15°C. Auson's multi-dimensional early warning system integrates CO₂, H₂, DMC gas concentrations, temperature, and pressure, advancing warning times to 30 minutes pre-incident while reducing false alarm rates to 0.3%.
Core Early Warning Technology Architecture of Industrial Panel PCs
2.1 High-Precision Data Acquisition Layer
The USR-EG628 integrates 16 ADC channels supporting nanoampere-level current detection and microvolt-level voltage sampling, meeting GB/T 34131-2023 requirements for current acquisition error ≤0.2%FS. In a Shenzhen energy storage plant deployment, its 24-bit high-precision ADC controls SOC estimation error within ±1.5%, tripling accuracy compared to traditional 16-bit solutions.
2.2 Edge Intelligence Decision Layer
Featuring ARM Cortex-M7 cores with hardware accelerators, the USR-EG628 executes VFFRLS-Noise adaptive CKF algorithms locally. During BYD Blade Battery testing, this achieved 92% accuracy in predicting temperature rise rates 15 minutes before thermal runaway—a 40% improvement over traditional Kalman filtering. Its built-in Lua scripting engine enables dynamic warning model updates without system restarts.
2.3 Rapid Response Execution Layer
Through hardware-level interrupt mechanisms, the USR-EG628 triggers protective actions within 50μs. In CATL energy storage cabinet testing, when monitoring a 25% voltage drop in individual cells, the controller executed triple联动 (main circuit disconnection, fire suppression activation, BMS data backup) in 8ms—20 times faster than traditional PLC controls.
