Five Questions Power Supply Professionals Should Ask Themselves about UPS Battery Maintenance and Replacement

Josh Johnson January 10, 2017

Scott Baer, Marketing Manager-Batteries, Vertiv Services

In a recent battery maintenance quiz sponsored by Vertiv, formerly Emerson Network Power, 71 percent of respondents accurately answered that during a power interruption, it only takes one bad cell to cause your data center’s uninterruptible power supply (UPS) to drop a critical load. Batteries are indeed the weakest link in the power chain and are historically a leading cause of costly downtime. Timely battery maintenance and replacement are essential to ensuring critical system availability.

A New Power-Cycling Strategy for Testing the Reliability of Power Electronics Modules

Josh Johnson December 14, 2016

Dr. John Parry, Mentor Graphics Corp.

The particular power cycling strategy you choose for high-power semiconductor devices, such as power transistors, diodes, MOSFETs, and IGBTs, during reliability tests can have a significant effect on predicted lifetime results even if the tests have similar initial parameters. Also, how you set up the measurements can affect the results of the power cycling tests. Read more about A New Power-Cycling Strategy for Testing the Reliability of Power Electronics Modules …

Battery Diagnostics On-the-Fly: Removing the “Black-Box” Stigma by Making Performance Transparent

Josh Johnson November 16, 2016

Isidor Buchmann, CEO & Founder, Cadex Electronics, Inc.     

Battery users imagine a battery pack being an energy storage device that resembles a fuel tank dispensing liquid fuel. For simplicity reasons, a battery can indeed be perceived as a vessel storing electrical energy; however, measuring energy flowing into an electrochemical device and then drawing it out again is far more complex than handling liquid fuel. While a hydraulic fuel gauge measures liquids moving in and out of a tank of known size, a battery fuel gauge reads units of current. Battery size is specified in ampere hours (Ah), and what makes estimating battery state-of-charge (SoC) and state-of-health (SoH) so challenging is an unsteady state; a battery loses capacity with each charge and leaks energy in the form of self-discharge.
