Online High Frequency UPS and its advantages

Aug , 26 2021

High frequency UPS: High frequency UPS is usually composed of IGBT high frequency rectifier, battery converter, inverter and bypass. The IGBT can control its opening and closing by adding control to the gate. The switching frequency of the IGBT rectifier is usually from thousands of Hz to tens of kHz (even up to a hundred kHz) relative to the 50Hz frequency that is far higher than the low frequenc...

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...

SOC-OCV test for Lithium batteries

Aug , 26 2021

OCV is very important for SOC estimation. It is a function of cell SOC and temperature. There are two methods to measure the OCV, namely coulomb titration and voltage relaxation. The former discharges and charges the cell with the same low current while measuring the terminal voltage. The OCV is defined as the average value of the charge and the discharge terminal voltage. The latter determines th...

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 degrade under ...

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 ...
