    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...

  • Effect of input capacitors between UPS and Generator

    Effect of input capacitors between UPS and Generator

    Jul , 18 2022
    Input capacitors used for filtering purpose cause pure apparent power to flow between the supply and the UPS. Such power is referred to as leading or capacitive power. Gensets can manage limited amount of pure leading power, as it interferes with the excitation circuit in the AC generator, leading to voltage oscillations and genset’s shutdown. Safe operating area charts show the allowed gensets’ l...

    Issues related to Battery for the datacenter application

    Jul , 22 2022
    The entire corporate world changed their culture in a very short time, to a predominantly work-from-home model due to Covid-19, many data center and IT professionals have been scrambling to manage this sudden shift in their network demands. The IT sectors are losing many jobs rapidly; the monthly loss is huge in the industry’s history. The news was a harsh reminder that no industry will be spared ...

    What are the soft costs of datacenter?

    Jul , 22 2022
    Data centers can’t afford to go dark. That’s why reliable critical power systems arecentral to their operation. Selecting and maintaining these systems comes at a price, but astronger understanding of “hard” and “soft” costs -- and what can be done to mitigate thelatter -- can protect the bottom line. Hard and soft costs vary from one operation to the next. In general, hard costs refer to the expe...

    What is a Micro Data center?

    Aug , 01 2022
    When people think about the data center, they always think that in a very large building. There are a lot of cabinets neatly arranged, cabinets filled with servers, and servers are shining positive light. It looks cool. A data center is a dedicated space within a building, or a group of buildings used to house computer systems and associated components, such as teleco...
