  • UPS power supply power supply method and daily use precautions

    UPS power supply power supply method and daily use precautions

    Aug , 29 2023
    Today, whether it is a computer room or a data center, UPS power supply has played a vital position. When the UPS power supply is power supply in the municipal power, it is the role of the voltage regulator and filter to ensure the normal operation of the equipment; when the municipal power is interrupted, it can provide it by providing its DC power supply part (battery pack, diesel generator, etc...

  • Lead-acid battery thermal runaway failure analysis when the battery is in the state of charge

    Lead-acid battery thermal runaway failure analysis when the battery is in the state of charge

    Sep , 04 2023
    Lead acid battery thermal runaway fault analysis When the battery is charged: There is a cumulative increase in battery temperature. When the heat accumulates to a certain extent during the warming process, the battery terminal voltage will suddenly decrease, forcing the current to increase suddenly, and the phenomenon of high battery temperature and damage to the battery is called thermal runaway...

  • Why only online UPS topology provides mission critical load protection

    Why only online UPS topology provides mission critical load protection

    Sep , 09 2023
    Why does only online UPS topology provides mission critical load protection? Modern, static UPS systems are broadly classified into three design architectures: on-line, off-line and line interactive. This post describes and compares the three types and explains why – for truly critical loads – online ups topology is the only acceptable approach. Facility executives today face increased demands for...

  • Interface level standards between digital systems

    Interface level standards between digital systems

    Sep , 09 2023
    Preface When we constrain the FPGA project, we often see such level standards, such as LVCOM18, LVCOS25, LVDS, LVDS25, etc. In fact, these are a series of level standards, in order to have a deeper understanding of the level standards, the following excerpts from the book "The FPGA Way" for the explanation of the level standards to understand. Dual Threshold Standard The so-called dual-threshold s...

  • Effect of temperature on the performance of lead-acid batteries

    Effect of temperature on the performance of lead-acid batteries

    Sep , 18 2023
    What are the effects of temperature on the performance of lead-acid batteries? From the chemical reaction equation of lead-acid batteries, PbO2 is on the positive plate, and Pb is on the negative plate. The electrical and physical properties of these two substances vary very little with temperature, so it can be said that the temperature effect of the discharge performance of lead-acid batteries i...

  • How do lithium batteries screen distribution groups?

    How do lithium batteries screen distribution groups?

    Sep , 19 2023
    The inconsistency between single batteries often causes problems such as too fast capacity decay and short life during the cycle of battery packs. Improving the consistency of batteries is of great significance to the popularization and application of lithium-ion batteries. 1 Inconsistency analysis Definition of inconsistency The inconsistency of the lithium-ion battery pack means that after the s...

  • Micropore system anatomy of AGM clapboard

    Micropore system anatomy of AGM clapboard

    Oct , 11 2023
    The performance characteristics of VRLA batteries are largely determined by the capillary characteristics of the AGM separator, that is, the ability to keep the micropores in the thickness direction of the separator filled with electrolyte and prevent the electrolyte from drying out and causing delamination. These properties are influenced by the micropore structure, especially the micropore distr...

    Lithium battery performance key indicators - internal resistance knowledge

    Oct , 13 2023
    First, the definition and role of internal resistance (1) Definition of internal resistance Internal resistance refers to the resistance encountered by the current passing through the inside of the lithium battery during discharge or charging. It is determined by the conductivity of the material inside the battery, the ion transport rate of the electrolyte, the contact resistance between the elect...

  • The role and importance of AGM partitions

    The role and importance of AGM partitions

    Oct , 19 2023
    AGM separator and transfer reaction between positive and negative plates Structure and function of partitions The AGM partitions used by VRLA have the following additional functions: Absorb the electrolyte (the third active substance of the battery) so that it does not flow. Provides a relatively large gas transfer hole for oxygen diffusion and thus facilitates the operation of the COC. High ionic...

  • Lithium battery internal resistance - AC resistance and DC resistance

    Lithium battery internal resistance - AC resistance and DC resistance

    Oct , 27 2023
    Resistance is a physical quantity that characterizes the degree of obstruction of circuit elements to current transmission. The internal resistance (internal resistance) of lithium batteries is one of the important indicators to evaluate the performance of batteries. In practical applications, the internal resistance of lithium batteries has three important roles: 1. It can be used to evaluate the...

    Method for providing the service life of valve-controlled closed lead acid Battery (VRLA)?

    Nov , 03 2023
    1 Temperature affects battery life: thermal runaway causes temperature rise: Valve-controlled closed lead-acid battery (VRLA) charging when the internal gas recombination itself is an exothermal reaction, so that the battery temperature rises, floating charge flow increases, the gas evolution increases, and the battery temperature rises higher, the battery itself is a "poor liquid", tightly assemb...
