Charging profile of a SLA and LiFePO4 battery

Aug , 26 2021

If you've recently purchased or are researching lithium iron phosphate batteries, you know they provide more cycles , an even distribution of power delivery , and weigh less than a comparable sealed lead acid (SLA ) battery . Did you know they can also charge four times faster than SLA? But exactly how do you charge a lithium battery, anyway? EverExceed recommends you select a charger designed for...

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 ...

Critical factors for LFP batteries in LEV application

Aug , 26 2021

Lithium batteries are lightweight and provide higher energy density than lead-acid or nickel–metal hydride (NiMH) batteries, creating a demand for them in electric vehicles (EV), energy storage, and consumer electronics. Compared to NiMH batteries, lithium batteries have a 50 percent greater capacity in watt-hours per kilogram (w-h/kg). The EV industry is demanding higher-efficiency batteries; in ...

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 ...

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...
