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 ...

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...

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...
