Samsung SDI's uninterruptible power supply (UPS) batteries have passed a fire containment test conducted by a global certification body, affirming their safety technology. UPS systems are critical infrastructure devices that provide emergency power stored in batteries to ensure stable operation during sudden power outages or voltage instability, particularly in AI data centers.
On July 14, Samsung SDI announced that it met all evaluation criteria in an indoor large fire test organized by UL Solutions. This test verifies whether a fire spreads to adjacent racks or systems after intentionally igniting modules within a UPS battery rack.
In this test, the ignited UPS battery module was completely consumed by fire, but there was no spread of flames, gas emissions, explosions, or ruptures to surrounding racks, meeting all performance and safety standards. Notably, the fire extinguished itself without the activation of overhead sprinklers.
UL Solutions introduced the indoor large fire test earlier this year to assess the risks of explosions and heat propagation in the event of an actual fire in a UPS. As major global tech companies and AI data center operators increasingly require 'fire safety verification' as a prerequisite for selecting battery suppliers, Samsung SDI expects to leverage these test results to highlight its differentiated safety competitiveness to global customers.
Samsung SDI explained that it applied heat propagation prevention technology and utilized lithium manganese oxide (LMO) in this test, along with its unique prismatic battery technology, which features an aluminum case resistant to heat and shock, and a vent for gas release.
In addition to UPS batteries, Samsung SDI plans to accelerate its market penetration in AI data centers and energy storage systems (ESS) based on its differentiated safety technology across various ESS products, including the Samsung Battery Box (SBB).
A company official stated, "Passing this test has validated our differentiated safety technology, and we will provide the most reliable solutions for customers in various markets, including ESS for AI data centers."
Meanwhile, Samsung SDI has secured over half of the volume in the last two government bids for ESS and is preparing for the upcoming third bid.
