Will Plug-In Hybrids Change The Data Center?

In a recent discussion with a group of infrastructure architects, power architecture, especially UPS engineering, was on the table as a topic. There was general agreement that UPS systems are a necessary evil, cumbersome and expensive beasts to put into a DC, and a lot of speculation on alternatives. There was general consensus that the goal was to develop a solution that would be more granular install and deploy and thus allow easier and ad-hoc decisions about which resources to protect, and agreement that battery technologies and current UPS architectures were not optimal for this kind of solution.

So what if someone were to suddenly expand battery technology R&D investment by a factor of maybe 100x of R&D and into battery technology,  expand high-capacity battery production by a giant factor, and drive prices down precipitously? That’s a tall order for today’s UPS industry, but it’s happening now courtesy of the auto industry and the anticipated wave of plug-in hybrid cars. While batteries for cars and batteries for computers certainly have their differences in terms of depth and frequency of charge/discharge cycles, packaging, lifespan, etc, there is little doubt that investments in dense and powerful automotive batteries and power management technology will bleed through into the data center. Throw in recent developments in high-charge capacitors (referred to in the media as “super capacitors”), which add the impedance match between the requirements for spike demands and a chemical battery’s dislike of sudden state changes, and you have all the foundational ingredients for major transformation in the way we think about supplying backup power to our data center components.
