Battery technologies and trends for UPS applications

Aug , 26 2021

Battery chemistries currently available for UPS backup include Lead-Acid, Lithium-ion (Li-ion) and Nickel-Cadmium. There are also non-battery technologies like flywheels and Super-Capacitors. However, this article focuses on the two types that currently dominate the data centre industry: Lead-Acid, which represent over 90 per cent of the UPS market share, and Li-ion, which is attracting increasing...

Some common questions and their answers about the lithium batteries in UPS applications

Aug , 26 2021

What are the primary benefits of switching to lithium based UPS batteries? The most common reason cited is the significantly longer service life. Lithium also provides a greater cycle life (the number of charge/discharge cycles ranges from extends into the thousands, versus approximately 500-600 for VRLA batteries), as well as a longer warranty. Furthermore, the lighter weight and smaller footprin...

Life Expectancy for a Lithium Battery in a Stationary Application

Aug , 26 2021

One of the key attractions for moving to lithium batteries is the battery life being multiples of what is possible with lead-acid batteries. Yet, with limited operating data in UPS applications available today, it’s natural for potential users to question how long lithium batteries will actually last. To address this question, it’s necessary to first understand how lithium batteries de...

The role of BMS for a UPS LFP battery pack

Aug , 26 2021

As a means of protection, most lithium battery systems of almost any string voltage require a battery management system (BMS) to maintain the cell operating conditions within the limits. These can range in complexity from just cell balancing to ones that monitor cell voltage; cell temperature and current; and, through the use of either semiconductor switches or relays, will disconnect the battery ...

How to calculate Solar Payback?

Aug , 31 2021

Solar energy is a rapidly growing industry, thanks to the dramatic drop in prices for solar energy systems in the past decade. In most cases it is more cost effective to implement a solar energy system than to buy electricity from the local utility company. Solar provides predictably priced electricity for 20-30 years, making it easy for businesses to forecast operational expenses. In top of that,...

Implementing a useful battery assessment system at low cost

Nov , 22 2021

In the battery system industry, some companies provide charger and battery systems to smaller, mission-critical applications; for some years, it has been clear that reducing the impact of battery failure is the best way to increase the user’s overall system reliability. In contrast to power electronics that can achieve MTBF in the range of 1 million hours, all VRLA batteries will fail between “now...

How to implement battery monitoring in a deployable product?

Nov , 27 2021

Standalone ohmic battery monitoring systems designed for data center application are not suited for a genset environment. Although ohmic monitors work, they are expensive (estimated at $2,000 for a 24-volt system), time-consuming to install, and require trained personnel to interpret their data output. To achieve widespread adoption in the genset market any battery monitoring technology will need ...

What are the recharge cycles phases of a Lead acid battery?

Nov , 27 2021

The fastest generally accepted way to charge a conventional (lead‐acid or NiCd) battery is with a constant voltage, a current limited battery charger that is capable of both “boost” and “float” output voltages. “Boost” charging applies a higher than normal voltage to the battery early in the charge cycle to charge the battery as quickly as possible. Later, once the battery is charged, charging vol...
