  • Charging profile of a SLA and LiFePO4 battery

    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...

  • SOC-OCV test for Lithium batteries

    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

    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

    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 ...

  • Relation between charge and temperature of LFP 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

    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...
