Battery Voltage

How closely do you watch the battery voltage of your battery cells? Would you know if your voltage was falling out of its ideal range? Battery voltage monitoring is regularly overlooked - which creates a huge problem. All it takes is a single bad cell or a fully discharged string and an entire site could easily go dark.

Unfortunately, monitoring batteries isn't always as simple as putting a single voltage sensor on your battery strings. To really understand the big picture, you need to understand lots of little pictures of cell voltage and temperature.

Why you can't live without battery voltage monitoring
Leaving your battery cells unmonitored opens the door for far too many problems - problems that are easily avoidable. Monitoring battery voltage has many benefits, the least of which is preventing outages.

When your battery cells are left unmonitored, you're in the dark and constantly guessing about their status. Creating a reliable network requires continuous network monitoring - otherwise a small issue can quickly turn into a serious problem.

What if your critical backup batteries are all discharged and power fails at a site? This is a far too common disaster because many companies don't take their backup power seriously - even if they think they do. With a battery monitor in place, you would have known your batteries were discharging long before it became an issue. You might, for example, have dispatched a portable generator that you might not have previously. These kinds of simple outages and headaches aren't hard to prevent - the key is knowing there's a problem.

Monitoring the health of individual cells
Since a single bad battery cell can dramatically degrade the performance of an entire string of batteries, it's critical you deploy a thorough battery monitoring system. Monitoring the entire string is better than no monitoring at all - but it's not the most effective way to improve reliability.

A good battery monitor will have sensors to monitor each of your cells individually - looking not just for low voltages but a difference between the cells and the average of all the cells. With this level of monitoring, you'll never have to worry about a single cell weakening an entire string of batteries.

Using temperature to pinpoint problems
It's not enough to only monitor voltage. Battery cells can get abnormally hot when they are failing - so included temperature monitoring can help detect battery issues long before they can cause serious issues. Early notification gives you the time you need to respond to problems in a controlled manner. Including temperature monitoring with your voltage monitoring is the only way to thoroughly and completely monitor your battery cells.

With this level of monitoring, you won't have to worry about a small issue snowballing into a serious problem. Network downtime is bad for everyone - it costs you a fortune and leaves your customers unhappy. Don't let unmonitored battery strings be a liability for your network.

With a battery voltage monitoring system like the BVM 48 G2, you can achieve superior reliability. You can prevent many outages - which will save you tons of money and keep your customers happy. That's a win-win scenario.
