    NiCd vs Lithium batteries (part-2)

    Feb , 21 2022
    NiCad (Nickel Cadmium) batteries ruled over the market for years. However, in recent years, they are getting challenged by newer Lithium-Ion batteries. Why? Well, we cannot tell you that in brief. It indeed requires a vivid discussion. To make the discussion or contrast evident, here, we shall dwell on various respects i.e. their history, electrochemistry, manufacturing cost, environmental im...

    There is a common misconception that the utility power we use, except for occasional power outages, is continuous and constant, but it is not. As a public power grid, the mains system is connected to thousands of various loads. Some of the larger inductive, capacitive, switching power supplies and other loads not only obtain power from the power grid, but also cause damage to the power grid itself...

    How to do the SOC-OCV test for Lithium batteries?

    Apr , 06 2022
    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 FAQ about the Lithium batteries for UPS

    Apr , 06 2022
    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...

    Uninterruptible Power System-Use of Inverters & Chargers

    May , 09 2022
    If you already have a pretty good idea about the available methods for converting ac power to dc power, an inverter covers the other direction: changing dc into ac. Normally, when we speak of an inverter, we mean a device that generates line frequency power from a dc source, to power conventional ac-powered loads such as a personal computer, or industrial controls and instrumentation. A UPS integr...

    Have you ever considered how you would evacuate people from a multistory building in case of power failure? Do you have responsibility for people coming and going from public buildings? If you do, you need to consider how you’re going to handle evacuation in the event of an extended power failure and are not equipped with a standby generator. It doesn’t need to be a dramatic situation just an exte...

    Temperature is very important for lithium- ion batteries. Low temperature will reduce the electrical performance of lithium- ion batteries (capacity, rate performance), but it can improve the storage life of lithium- ion batteries. High temperature can improve electrical performance (capacity, rate performance), but It will reduce the stability of the electrode/electrolyte interface and cause a ra...
