IEC certification for lithium-ion batteries

Lithium Guardian Batteries provide safe, reliable, low cost energy storage for mission critical system operators.

Green Cubes has announced International Safety Certification IEC 62368 certification of the Lithium Guardian Battery Backup Units. The Lithium Guardian family of backup batteries are designed for rack mount installations in the Telecom and Data Center industries.

The Telecom and Data Center facilities operate 24 hours a day, 7 days a week, supporting mission critical functions. Traditionally, large lead-acid batteries are used to provide backup power. Li-ion batteries allow operators to store more energy in smaller spaces to power equipment longer when the grid power goes is unavailable. Lithium Guardian batteries serve this market by providing safe, clean, and reliable backup power in a small, lightweight, and cost-effective package.

The Guardian product family provides complete power system solutions to telecom and other 48V system operators with products providing rectification, power management, and energy storage. The Lithium Guardian Battery Unit (GBU) is a 48V, 105 Ah, 5kWh Lithium Iron Phosphate (LFP) battery offering reliable energy storage in a small lightweight form factor. With a design life of over 10 years, and well over 3500 cycles the LFP GBU provides operators with a long lasting energy storage solution.

“Safety and reliability are paramount to our requirements when designing Li-ion batteries. We verify our designs are safe and reliable for their application by real world testing and certification to globally recognized IEC standard,” said Mike Davis, Chief Revenue Officer at Green Cubes. “Lithium Guardian Batteries were designed to operate with a wide range of equipment; from radios, routers, to HVAC, our batteries must work. Achieving IEC 62368 assures customers that these batteries will provide power to their equipment safely and reliably.”

IEC 62368 is an internationally recognized standard to verify safety and reliability of electronic devices in telecom applications. The Green Cubes GBU has been evaluated by engineers and tested in the lab to ensure that when integrated in operator systems the battery will remain safe and not adversely affect other equipment. Previously, the Lithium Guardian 3U battery has been tested and certified to UN 38.3 for international shipping. The Guardian Lithium Batteries are currently under evaluation with multiple industrial and telecommunication operators. Commercial shipments are scheduled for December 2022.
