Evolion® Li-ion battery: for compact and universal energy back up
Saft Evolion® Li-ion battery offers a unique combination of float charging capability and high cycling performance. Its key features include: high energy back up in a compact, weight-saving package; high efficiency; long calendar and cycle life – even when operating in extreme temperatures; zero maintenance requirements; an environmentally friendly design.
Evolion®’s high volumic energy means it only needs half the space required by a conventional VRLA battery. For remote installations, the zero maintenance design coupled with intelligent remote supervision eliminates the need for routine site visits. The use of lightweight Li-ion technology also addresses the challenges of maximum floor loading requirements in Central Offices. Evolion® is four to ten times lighter than conventional batteries, depending on the applicationmaking it feasible to colocate the battery system with the active telecom equipment, even on raised floors.
