远景交易型储能完成大规模燃烧测试！5cm间距 49小时零蔓延

Core Viewpoint - The article highlights the successful completion of a large-scale fire test for the Envision Energy's smart trading energy storage system, demonstrating its superior performance in fire safety and system security, setting a new benchmark for energy storage asset protection [1][14]. Group 1: Test Overview - The fire test was conducted under the supervision of CSA Group and involved four Envision smart trading energy storage systems, each with a capacity of 5 MWh, charged to 100% state of charge (SOC) [3]. - The test was designed to simulate real-world scenarios, with the systems placed in close proximity, challenging industry standards for safety spacing [4]. Group 2: Test Results - The A unit burned for 49 hours and 32 minutes, reaching a peak temperature of 1297°C, while the B, C, and D units maintained low temperature increases, with B at 35°C, C at 44°C, and D at 43°C, all well below the warning thresholds for battery cells [6][9]. - The ignition process took nearly 3 hours, which is over 50% longer than typical ignition times, allowing for ample time for firefighting measures [7]. Group 3: Environmental Impact - The smoke generated during the test was fully collected and treated, ensuring no harmful emissions were released, thus establishing a standard for environmentally friendly fire testing in energy storage [11][13]. Group 4: Safety and Commercialization - Envision's energy storage system incorporates a three-tier safety system and a big data fire warning system, effectively managing thermal runaway risks and ensuring no safety incidents have occurred across over 300 global projects [14]. - The successful fire test allows for the quantification of safety risks in energy storage, creating conditions for insurance participation in energy storage investments and operations, further promoting commercialization in the sector [14].
