Core Viewpoint - REPT BATTERO has successfully passed a large-scale fire test for its 5MWh energy storage battery cabinet, demonstrating its ability to prevent thermal runaway and setting a new safety benchmark in the energy storage industry [21][22]. Group 1: Test Overview - The fire test involved a fully charged 5MWh battery cabinet that burned continuously for 14 hours, simulating five types of composite fire scenarios [21][22]. - The test was conducted under extreme conditions, with the battery storing maximum energy and exhibiting high chemical activity, which significantly increases the risks associated with thermal runaway [22][23]. Group 2: Testing Methodology - Ignition was triggered using a combination of internal heating and external propane flame injection, creating a realistic simulation of catastrophic accident scenarios [23]. - The test design included a rigorous setup that removed active fire suppression systems, relying solely on the battery cabinet's passive safety features to manage the fire [13][20]. Group 3: Safety Performance - The test successfully prevented the spread of thermal runaway, with the highest flame temperature reaching 1380°C while maintaining the internal temperature of adjacent battery cells below 57°C, indicating effective thermal management [7][20]. - The testing apparatus was designed to simulate the harshest fire scenarios, adhering to multiple core safety standards, including CSA/ANSI C800:25, NFPA 855, and UL 9540A [22]. Group 4: Data Collection and Analysis - Over 600 temperature monitoring points were deployed during the test, allowing for comprehensive data collection on the fire's behavior and the battery's performance [20]. - Post-test inspections revealed that the battery cabinet's structural integrity remained intact, with no collapse or significant damage, further validating the product's safety design [20].

Core Viewpoint - The article highlights the successful completion of an extreme fire test conducted by Ruipu Lanjun on its Powtrix® 5MWh energy storage battery system, demonstrating its enhanced safety performance under severe conditions [2][20]. Group 1: Testing Conditions and Methodology - The fire test was conducted under extreme conditions, simulating a worst-case scenario with a fully charged battery, which poses the highest risk of thermal runaway and fire spread [3][4]. - The test involved a combination of internal heating and external propane flame exposure, leading to a sustained burn of approximately 14 hours after a 3-hour ignition trigger [4][19]. - The test design included exposure to five types of fire (solid, liquid, gas, metal, and energized equipment), assessing the battery system's resilience against complex fire scenarios [4][10]. Group 2: Safety Performance and Results - The Powtrix® battery system successfully prevented thermal runaway from spreading to adjacent battery units, with the maximum flame temperature reaching 1380°C while maintaining the internal temperature of neighboring units below 57°C [7][20]. - The test was conducted without active fire suppression systems, relying solely on the battery's passive safety design, which proved effective in containing the fire [13][20]. - Over 600 temperature monitoring points were deployed during the test, providing comprehensive data collection and analysis of the combustion process, which received commendation from fire safety engineering experts [19][20]. Group 3: Industry Implications - This rigorous testing sets a new benchmark for safety in the energy storage industry, showcasing Ruipu Lanjun's capabilities in battery technology development and system safety design [20]. - The successful demonstration of the Powtrix® system's safety features contributes significantly to advancing the overall safety and reliability standards within the energy storage sector [20].
