    How to select an inductor

    Sep , 16 2023
    Inductors - also known as chokes, reactors, and dynamic reactors.Together with capacitors and resistors, they are known as the three major passive components, and relay containers and resistors have rapidly developed into chip based components. Self induction phenomenon: The electromagnetic induction phenomenon that occurs when the current flowing through the conductor itself changes. When a coil ...

  • 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...

    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...

    What is the difference between single phase and three phase UPS?

    Oct , 16 2023
    When purchasing UPS for your business or organization, many factors should be taken into consideration, among which the choice of power supply between single phase UPS and three phase UPS is the foremost one. Though both of the UPS offer consistent backup power for dealing with unexpected situations, they have different roles. Here is a brief introduction of single phase vs three phase for those w...

    How to calculate the required ups load capacity?

    Oct , 19 2023
    Measured in “watts”, UPS load capacity is an important factor to consider when choosing a UPS (uninterruptible power supply). It determines how many electronic devices the UPS system can support. This post will tell you how to choose the right UPS with required UPS load capacity in the following four steps. Clarify UPS Measurement Units UPS systems are rated either in kilowatts (kW) or in kilo-vol...

    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

    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...
