Envision Energy Sets a New Standard with Record 49-Hour Fire Test for Energy Storage Safety

Envision Energy Sets New Safety Expectations



Envision Energy, a frontrunner in green technology, has made waves in the energy storage sector by completing an unprecedented large-scale fire test of its smart energy storage system. This ambitious undertaking aimed not just to showcase technological prowess but to elevate the benchmarks for safety and environmental stewardship in energy storage systems. The test took place in Shanghai under the vigilant oversight of the Canadian Standards Association (CSA Group) and seasoned North American Fire Protection Engineers (FPEs), ensuring compliance with the stringent CSA C800 standard—a consensus criterion shaped by input from insurers, regulators, and industry experts.

World’s Densest BESS Configuration



The fire test was remarkable in its execution. It simulated the most extreme on-site conditions imaginable, placing four fully charged 5MWh Envision Smart Energy Storage containers—designated A, B, C, and D—within just 5 centimeters of each other. This ultra-dense configuration starkly contrasts with the traditional industry norms, which recommend spacing anywhere from 3 to 5 meters apart. The test’s layout was dubbed the most energy-dense fire test ever, creating a challenging environment due to increased thermal coupling and restricted airflow. Significantly, the testing burned without any interference, allowing a raw demonstration of system resilience.

Container A underwent a grueling burn for 49 hours and 32 minutes, reaching an astonishing peak temperature of 1,297°C. In stark contrast, the internal battery temperatures of the adjacent containers B, C, and D remained exceptionally stable at only 35°C, 44°C, and 43°C respectively—well within the normal operating range. Remarkably, Container A held its structural integrity, exhibiting no deformation, collapse, or loss of sealing gaskets, while the neighboring units sustained no damage whatsoever.

A Critical Window for Response



Following the initiation of a fire—strategically set to mimic the worst-case scenario—ignition took nearly three hours. This delay allowed more than sufficient time for early detection and response, surpassing typical ignition timings and providing a crucial window for emergency measures. The approach employed cutting-edge methods, utilizing synchronized heating to four battery cells from which nano-level thermal insulation was removed.

Emphasizing Environmental Safety



A hallmark of this fire test was its commitment to environmental safety. All combustion gases from the burning container were efficiently captured through overhead smoke hoods, later analyzed and rendered harmless through advanced treatment systems. Remarkably, the test resulted in zero emissions, no odors, and absolutely no pollution—marking a groundbreaking benchmark for eco-friendly fire testing in energy storage.

AI-Powered Safety Mechanisms



Envision's Smart Energy Storage System is supported by advanced AI capabilities designed for comprehensive lifecycle asset protection. This multi-layered safety architecture, covering cellular, pack, and system levels, ensures exceptional risk containment. Envision’s storage solutions have been deployed worldwide in over 300 projects without a single safety incident to date.

This historic fire test reaffirms that even in unlikely fire scenarios, Envision's technology can effectively manage risks within individual containers. Through quantitative safety results, insurers can gain increased assurance in underwriting storage assets, ultimately promoting broader commercial acceptance and accelerating the shift toward secure, large-scale energy storage solutions.
