Phosphate batteries run at higher temperatures for data centre power

Saft has launched its second generation lithium ion battery for data centre and backup power.

The Flex’ion Gen2 battery packs are manufactured in Europe and provide up to 220 kW per cabinet for data centre power as well as telecoms offices and hospitals. This is 40 percent higher than the first generation packs.

The modular packs from Saft use a ‘Super-Phosphate’ chemistry that allows them to run reliably at higher temperatures of 35º C, reducing the Heating, Ventilation and Air-conditioning (HVAC) requirements, minimizing energy bills and carbon emissions. Its low-cobalt content of less than 1 percent and the primary materials sourced from responsible suppliers under the Responsible Materials Initiative (RMI) enables a highly sustainable and environmentally friendly system.

“Data centre operators want UPS batteries that are safe, reliable, sustainable, powerful and long-lasting. We can provide that with our Flex’ion Gen2, which we can deliver with a short lead time, backed by a five-year warranty,” said Guy-Patrick de Broglie, Marketing Director at Saft.

The packs have passed rigorous testing under the UL 1973 and UL 9540A method and are certified as safe under the ICC International Fire Code (IFC 2018) and NFPA 855 standards. The industrial design means that it is certified for use without a built-in fire suppression system or an air separation gap of 1m (3ft) between cabinets for data cetnre power designs.

By eliminating this air gap, operators can minimize the footprint of their UPS and dedicate more space to server racks and other services. This minimizes the space required and the Total Cost of Ownership (TCO) of the data center overall.

Other factors that reduce the TCO are the long calendar life of over 20 years, the low maintenance and the lightweight design. The li-ion batteries are six times lighter than valve-regulated lead-acid (VRLA) batteries, which is important for data centre power in buildings with limited load-bearing capacity.
