    What factors are affecting the side reactions of lithium deposition?

    Sep , 17 2021
    When charging lithium ion battery, Lithium precipitation not only reduces the performance of the battery and greatly shortens the cycle life, but also limits the fast charging capacity of the battery, and may cause disastrous consequences such as combustion and explosion. In a series of articles we will discuss about the problems from the macro scale of lithium-ion battery, working conditions, gra...

    Lithium battery failure model-explain the phenomenon of lithium evolution in graphite anode: part-2

    Nov , 01 2021
    During the long-cycle cycle, the reversible capacity of the lithium-ion battery will continue to decrease due to the reduction of active materials, the precipitation of metal lithium, the continuous consumption of electrolyte, the increase of internal resistance and thermal runaway. Among them, the lithium evolution phenomenon of the graphite negative electrode is the most important cause of batte...

    Things You Must Know Before Buying A Residential Energy Storage Battery

    Nov , 09 2021
    With the requirement for energy growing by leaps and bounds in all aspects of life, it is wise to save energy for the future, instead of wasting away the excess. This is where a residential energy storage battery comes into the picture. When attached to the grid-based system, the battery stores sustainable energy and supplies it during the times when you cannot gain access to solar power or other ...

    What are the recharge cycles phases of a Lead acid battery?

    Nov , 27 2021
    The fastest generally accepted way to charge a conventional (lead‐acid or NiCd) battery is with a constant voltage, a current limited battery charger that is capable of both “boost” and “float” output voltages. “Boost” charging applies a higher than normal voltage to the battery early in the charge cycle to charge the battery as quickly as possible. Later, once the battery is charged, charging vol...

  • What is the right duration of Phase 2 of a charging cycle?

    What is the right duration of Phase 2 of a charging cycle?

    Nov , 27 2021
    The duration of Phase 1 is determined by the battery’s depth of discharge, the ratio of charger ampacity to battery capacity, and whether there are parasitic DC loads connected to the system. Although the duration of Phase 1 does vary, we are not concerned with this variation since, once the battery capacity, charger output, and DC loads are installed, we have no means to change the duration of Ph...

  • What is Dynamic Boost and how does it works?

    What is Dynamic Boost and how does it works?

    Dec , 03 2021
    As with the current‐controlled automatic boost system, Dynamic Boost includes no pre‐programmed boost timer. Unlike the current‐controlled automatic boost system, however, Dynamic Boost automatically adjusts boost duration to take into account differing parasitic DC loads and other variables discussed above. The principle behind Dynamic Boost is simple and straightforward. Refer back to Figure 1. ...

    How a new intermittent charging algorithm addresses premature SLI battery failure?

    Dec , 06 2021
    A new charging algorithm addresses the problems of short genset battery life and sudden battery failure discussed above, while meeting the regulatory needs to deliver non-stop DC power to critical applications. The principle is simple and straightforward. Emulate the beneficial intermittent vehicle charging regime for which SLI batteries were originally designed, but continue charger operation to ...

    What is the Life Expectancy of a Lithium Battery for a stationary application?

    Dec , 10 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 battery packs degrade un...
