Battery Backup Thermal Runaway Fears? Render it Harmless Through Continuous Monitoring

Josh Johnson April 16, 2016

Tom Shannon, Director of Business Development • BatteryDAQ, Inc.

Thermal runaway is the disaster no one saw coming until it is too late. It sounds like a horror movie, and it could well be, if batteries are not properly maintained. Every article on the subject will point out something like “If the design of the battery, coupled with the installation location, allows for proper dissipation of increased battery temperatures, thermal runaway is unlikely”.

Tom Shannon, Director of Business Development • BatteryDAQ, Inc.

It is an established practice for design engineers to follow a process for selecting the best battery for a project or application, by submitting the choices through a balanced approach that compared technical requirements and goals, to cost and ongoing maintenance requirements.

The Sound You Hear is Completely Normal

Have you ever had trouble with your car and taken it to the shop for repair, only to have the mechanic tell you that there’s nothing wrong with it? I used to have an old truck that made a weird rattling noise in damp weather. Nobody ever figured out what it was, and the conclusion was that it was supposed to sound that way. (I drove that truck for 15 years before I finally traded it in a few weeks ago, so I guess it must have been fine.) Read more about The Sound You Hear is Completely Normal …

The Path of Least Resistance

One (almost literal) “rule of thumb,” which I learned some years ago, was that if you couldn’t hold your finger on an IC for more than one second without feeling pain, the chip’s case temperature was probably above 50ºC. While I don’t recommend this technique as a substitute for doing actual thermal measurements on your PCB, it was an interesting discovery at the time… and of course it was also easier to do when IC packages were a little bigger than they are now.

"Good Vibrations"

The word “resonance” has always been interesting to me, even when I couldn’t provide an accurate definition of it. There are so many different meanings, most of which have some connection to each other. As an electrical engineer, my first reaction at hearing the word now is to think of a tuned LC circuit.
