A battery management system is essential for the continued uptime and health of your data center. So it makes sense that when you've bought and installed one, you get the most out of it. We've recently published a new insights paper, How to make the most of that battery management system you just bought, and it's aimed at illustrating how to prevent your new BMS from becoming 'shelf-ware' - which basically means something that's underutilised. Putting your BMS on the ‘shelf’ is a missed opportunity for any data center operation, when it has the potential of being ‘Protect-your-reputation-ware’ when there is an outage, or just in terms of managing your battery replacement budget. The insights paper covers the essential actions a data center manager needs to take to make sure you're getting the best bang for your buck, and includes: Sorting ownership early - it's important to determine who's taking responsibility for your BMS, so that the conditions are correct, regular reports and data reviews are done, and there's agreement on procedures. Make the most of monitoring - event-based and ongoing reporting data from your BMS delivers real value. It's the heart of what a BMS does, and there's so much you can learn by keeping a close eye on the data. Treating your BMS as a live resource - the trick here is to not look just at the battery, but the whole environment it operates within. Not only do you want to prevent your BMS from becoming 'shelf-ware', you want to turn it into a tool that winds up being 'protect-your-reputation-ware'. The insights paper offers 7 important tips on how you can go about this, from making sure it's properly implemented and networked to making the most of your suppliers' expertise. When you've got a lot on your [...]
This is the sixth in a series of units that will educate the reader on the part played by a battery in an uninterruptible power system (UPS). Following are definitions of terms that are used throughout this collection of technical papers.
This blog, discussing battery Environmental and safety considerations, is the fifth in a series of units that will educate the reader on the part played by a battery in an uninterruptible power system (UPS). Environmental considerations fall into two categories: - the effects upon the battery by the environment in which it sits (small “e”); and - the effects of the battery upon the Environment in which it was produced, used, and disposed (big “E”) Impact of the environment on batteries Earlier units have discussed the impact of such things as temperature and grid reliability upon the life of a battery system. We will simply state here that it is wise to follow the manufacturer’s recommendations. A lead-acid battery, and in particular a VRLA battery, needs: well ventilated and temperature-controlled air flow. Cells that are packed tightly against each other will not be able to dissipate heat. The result is that cells in the middle of a row will run hotter – and therefore die sooner – than cells at the end of a row. Likewise, cells on the bottom shelf or tier will be cooler – and therefore live longer – than cells at the top of a cabinet or rack. Hot cells are more likely to vent gas, which then must be ventilated to prevent accumulation to hazardous levels. clean air. Dirt and humidity can have a corrosive effect on the battery, and can even be conductive, creating short circuits. Batteries should be inspected and cleaned periodically. chemical free maintenance. No chemical should ever be used to clean a battery unless it has been approved and/or recommended by the manufacturer. Some chemicals can deteriorate the cell container, causing leaks. sunshine-free location. UPS batteries should never be installed outdoors where they can be exposed to the damaging effects of [...]
Data centers have nowhere to hide in this digital age, so tools that help them avoid outages and understand exactly how they are performing are becoming critical.
Despite a century of experience, collective knowledge, and wide-spread preference for lead-acid batteries, they are not without some short-comings. An earlier unit mentioned a couple of issues. In this unit we go into more depth about how, when and why a lead-acid battery might be made to fail prematurely. Most conditions are preventable with proper monitoring and maintenance. This list is not all inclusive, but some of the main considerations are...
Dr Martin Spencer of DataCentre220 was in the market for a new UPS and selected CBS Batteries and PowerShield as the best options. This article, featured in ElectroLink Magazine, discusses the benefits of each and how they came to be selected.
