Aging of Lithium Batteries

Aug , 26 2021

Aging is an unavoidable process caused by side reactions present in all electrochemical devices including battery cells. It may result in significant changes of capacity and resistance of a device over time and must, therefore, be considered in the system layout phase (e.g., necessity of over-sizing initial capacity) as well as in the system operation phase (e.g., adapting maximum allowed cell dis...

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 desig...

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...

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 ...

LiFePO4 batteries Vs NCM batteries

Aug , 27 2021

Lithium iron phosphate (LiFePO4) and Lithium Nickel Manganese Cobalt Oxide (NCM) are both members of the lithium-ion battery family. A Li-ion Battery is composed of four main parts: cathode, anode, electrolyte and separator. Battery type is usually named after its cathode materials such as NCM battery or LFP battery. Both of them have become popular nowadays for Solar, Telecom, UPS, Street lightin...
