How to Understand UPS

Aug , 26 2021

UPS, namely, uninterrupted power supply is a type of uninterruptible power supply with energy storage device, inverter as main component, and constant voltage and constant frequency. It is mainly used to provide uninterrupted power supply for single computer, computer network system or other electrical and electronic equipments. When the electric supply input is normal, UPS will stabilize the volt...

Why you can't choose a cheap lithium battery?

Aug , 26 2021

As lithium batteries have grown in popularity, they have inadvertently created a significant issue that could rob consumers and businesses of thousands of dollars. Fuelled by a lack of regulation by Global Standards, a technology that is widely misunderstood and globalised has allowed battery cowboys to import cheap, inferior products that are faulty and potentially dangerous. These products under...

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...

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 ...

Relation between charge and temperature of LFP battery

Aug , 26 2021

During charging and discharging cycles, battery cells face over current, over voltage, and over temperature conditions. The charging process for Lithium batteries consists of two phases: constant current and constant voltage. In the constant current charging phase, the charge current is applied to the battery until the voltage limit per cell is reached. Li-ion batteries cannot accept a higher volt...
