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

    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...

  • Solar battery life time

    Solar battery life time

    Aug , 08 2022
    There are two ways to answer this question and the first is to determine how long a solar battery can power your home. In many cases, a fully charged battery can run your home overnight when your solar panels are not producing energy. To make a more exact calculation, you’ll need to know a few variables, including how much energy your household consumes in a given day, what the capacity and power ...

  • Do Ferro resonant chargers still have a place in battery charging?

    Do Ferro resonant chargers still have a place in battery charging?

    Aug , 15 2022
    One of the larger battery/charger companies selling chargers in the USA have announced that they are no longer manufacturing Ferro resonant chargers and have set 7/31/15 as the last date to accept orders.Is there something wrong with Ferro resonant charging that should make all charger companies follow that lead? Let’s consider Ferro resonant technology. The purpose of a Ferro resonant transformer...
