  • Battery charging tutorial-Part 2

    Battery charging tutorial-Part 2

    Apr , 18 2022
    Equalization Equalization is essentially a controlled over charge. Some charger manufacturers call the peak voltage the charger attains at the end of the BULK mode (absorption voltage) an equalization voltage, but technically it's not. Higher capacity wet (flooded) batteries sometimes benefit from this procedure , particularly the physically tall batteries. The electrolyte in a wet battery can str...

    DC-DC Converters-A suitable alternative to battery chargers

    May , 09 2022
    What if you had all the power you wanted or needed at 125 Vdc, but your site manager suddenly handed you a requirement for 24 Vdc to run some communication gear? You might tell him to buy a 24 V battery and a 24 V battery charger. But, these elements come with costs: initial, maintenance, and probable future battery replacement. There is another way: for approximately the same cost as the battery ...

    UPS For Lift Application

    May , 30 2022
    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...

  • What types of monitoring and recording devices are suited for high rate charging?

    What types of monitoring and recording devices are suited for high rate charging?

    Jun , 20 2022
    The higher the charging rate, the more critical it is to monitor the charging process to prevent permanent capacity loss. In efforts to preserve battery life, Fast and Opportunity charging incorporates a method of monitoring battery electrolyte temperature and/or internal resistance and adjusting charging current as necessary. Although these monitoring devices can have a very positive impact on ba...

  • Efficiency of DC power system

    Efficiency of DC power system

    Jun , 27 2022
    In this article we will explain the efficiency of DC systems and progress to AC systems on the next article. In very basic terms, efficiency is the measure of how much power is not being wasted by a system. More waste is less efficient. In electrical systems, we measure the power entering a system in watts; the unit of measure for work performed. Efficiency is the ratio of (Power-In) -vs. - (Power...

    Explore and analyze the thermal power of Li- ion cells and battery packs (part-1)

    Jul , 04 2022
    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...
