Saft launches Flex’ion for high power UPS systems

March 30, 2018


French battery firm Saft has launched a new battery system designed for high power UPS applications in “mission critical facilities” such as datacentres and oil and gas installations.


Saft said its Flex’ion system offers a range of energy and power combinations for applications from 1 to 500kWh and 10kW to 2.3MW.


The high power range (46 P Fe) offers a backup time optimised between one second and 15 minutes, Saft said. 


The system’s advantages over conventional lead-acid products include “a reduced footprint with one third of the volume and one sixth of the weight, 20 years calendar life, 10 times more cycle life and maintenance-free cells”.


In addition, “Flex’ion delivers a reduced total cost of ownership, an industry-leading power and energy density and close to 100% charge-discharge efficiency that reduces power consumption”, Saft said. “Its cutting-edge design includes an intuitive human-machine-interface and a front panel visual indication of the battery’s condition.”


Flex’ion features battery modules, a battery management system (BMS) and a proprietary Intelli-Connect power box. The battery modules fit standard 19-inch racks and are mounted in Saft designed cabinets, “ensuring reduced floor space in battery rooms”, the company said. “The inherent intelligence afforded by the BMS offers an array of monitoring capabilities, including system state-of-charge and state-of-health.


Saft product manager Nick Finney said the system’s development started by “choosing the right chemistry answering customers’ needs… super lithium iron phosphate (SLFPTM) cells offer superior performance over conventional technologies, while maintaining the highest levels of safety, reliability and availability”.


“This patented chemistry invented by Saft R&D has a flat discharge curve, which is an optimum fit for UPS systems that supply constant power,” Finney said.


The Flex’ion battery systems are designed and manufactured at Saft’s lithium-ion sites in Florida, France and the Czech Republic.
