Batteries are critical components in any uninterruptible power supply (UPS). Whether we consider an industrial facility, a data center, or the critical power supply to relays and control components of utility systems, the performance of batteries is instrumental to ensuring system availability. Without proper attention and care for batteries, critical infrastructure is put at risk as battery failure is the number one cause of UPS problems. To protect against battery failure and expensive downtime, preventive battery maintenance is key.

About a year ago, I wrote a post about resonance and how it relates to the wireless power systems we’ve been developing at TI to enable convenient charging of mobile devices. Since that time, the industry has made a lot of progress in bringing wireless power solutions to the next level. While many people may still consider wireless power an “exotic” or niche technology, there are already tens of millions of portable devices with wireless charging capability in the hands of end users.

When striving to achieve consistent and efficient operation, the UPS system is critical to data center emergency power systems. While tests and assessments are often completed to safeguard these systems, a UPS is only as reliable as the batteries that support it. In fact, recent Emerson Network Power research on critical infrastructure shows that nearly 37 percent of down units are due to battery failure.

Batteries may be the most “low-tech” components supporting today’s mission critical data centers, but battery-related failures account for more than one-third of all UPS system failures over the life of the equipment. Since the continuity of critical systems during a power outage typically is dependent on a data center’s power equipment, comprised of UPS and their respective battery backups, it could be argued that batteries are one of the most important components of the data center.
