全球首次！华为数字能源完成智能组串式构网型储能泄爆实证测试

Core Viewpoint - Huawei Digital Energy has successfully completed the explosion-proof test for its LUNA2000-5015 series energy storage system, demonstrating its technical strength in safety protection and risk control in energy storage systems [2][5]. Group 1: Test Results and Standards - The UL 9540A standard is a key safety testing standard for evaluating thermal runaway and its propagation risks in battery energy storage systems, influencing the admission of energy storage projects globally [4]. - The explosion-proof test was conducted under extreme conditions, where the energy storage system's explosion vent effectively opened, allowing for rapid pressure release while maintaining the integrity of the box structure [5]. - The test results provide credible data support for subsequent large-scale combustion tests, establishing a foundation for standardized explosion-proof testing in the industry [5]. Group 2: Safety Design Layers - The energy storage system incorporates a multi-layered safety architecture, including: - First layer: Directed smoke exhaust design to reduce the risk of smoke accumulation within the box [8]. - Second layer: Active exhaust design to control gas concentration below 25% LFL in case of failure of the first layer [8]. - Third layer: Precise explosion venting design to mitigate risks during an explosion [8]. - Fourth layer: High-strength box design to ensure structural integrity during an explosion, safeguarding personnel [8]. Group 3: Future Directions - Huawei Digital Energy aims to continue enhancing safety compliance and reliability throughout the lifecycle of energy storage technologies, collaborating with industry partners to iterate on safety technologies and testing methods [5].
