The Future of Data Center Power Systems? Smarter, More Efficient UPS Systems, powered by Lithium Ion Batteries

For decades, data center back up power has depended on VRLA (Valve-Regulated Lead-Acid) batteries which are inefficient and run down rather quickly. According to the Ponemon Institute, UPS battery failure was the top root cause of unplanned outages in the two years leading up to the study. As most people know, that is because VRLA batteries run down suddenly, often without warning.
  
But you can get the flexibility around the critical power configuration in your data center from Lithium Ion batteries, lowering the total cost of ownership and enabling advanced energy storage technologies.
  
Smarter uninterruptible power supplies equipped with Lithium-Ion batteries, provide the data center managers with load management and peak shaving capabilities and may soon be able to help the facility operate differently with the electric grid. So, why are the Lithium-Ion batteries enabling the data center of the future? Longer life, lower cost, better reliability, among others.
  
Discover our view on how you can best benefit from this new energy storage technology, from two of our best experts: Jeff Kessen and Peter Panfil, in the video below.

Smarter, More Efficient UPS

  

New battery alternatives will present opportunities for the broad adoption of UPS systems capable of more elegant interactions with the grid. In the short term, this will manifest in load management and peak shaving features.

Eventually, we will see organizations using some of the stored energy in their UPS systems to help the utility operate the electric grid. The static storage of all of that energy has long been seen as a revenue-generator waiting to happen.

Smarter, More Efficient UPS Systems

  

Arunangshu Chattopadhyay, Vertiv’s Director for Power Product Marketing in Asia, talks about smarter, more efficient UPS systems as one of the upcoming trends this year.

Do the benefits of Lithium-Ion batteries (LIB) outweigh the cost?

  

In simple terms, yes! Unlike the VRLA batteries, which support critical applications currently and need to be replaced every 4 to 5 years, you’ll feel a relief immediately by deploying LIBs. We’ll tell you why in a bit.

Just think of the number of batteries deployed in a data center. Then consider the what a constant replacement cycle for this high quantity means. And this is just the beginning. There’s more than meets the eye when it comes to Lithium-Ion batteries:

  • LIBs have almost a 4-times longer life than VRLA.
  • LIBs weigh up to 60% less than VRLA, which gives you reduced floor- loading thresholds and allows for flexibility in battery location. This was simply not possible with VRLA batteries, especially in sites built upon high-rise buildings.
  • LIBs are up to 70% smaller than VRLAs. This means saving space for better use or reducing capital construction costs.
  • LIBs operate at a higher ambient temperature than VRLAs. Without degrading. This saves on cooling costs and allows for flexibility with battery location.
  • LIBs also last 18 months unattended, where VRLAs require a “top off” charge every six months.
