  • Self-discharge measurement of lithium batteries: resting and dynamic measurement methods

    Self-discharge measurement of lithium batteries: resting and dynamic measurement methods

    Jun , 14 2023
    The measurement methods of self-discharge of lithium-ion batteries are mainly divided into two categories: 1) static measurement method, which obtains the self-discharge rate by standing the battery for a long time; 2) Dynamic measurement method to realize the parameter identification of the battery in the dynamic process. Static measurement method At present, the mainstream self-discharge measure...

  • Preparation of lead-reduced graphene oxide nanocomposites and their applications

    Preparation of lead-reduced graphene oxide nanocomposites and their applications

    Jun , 14 2023
    The shortcomings of lead-acid batteries are: low energy density and short cycle life. Lead sulfate formed by the negative plate of the lead-acid battery during the discharge process, after the battery is placed, the small particles of lead sulfate will be converted into large particles of lead sulfate, and the large particles of lead sulfate will not be converted into lead during the charging proc...

  • Why Choose a Lithium-Ion UPS Battery?

    Why Choose a Lithium-Ion UPS Battery?

    Jun , 21 2023
    Although lithium-ion UPS systems have been around for decades, most people have been hesitant to choose this option because they were more expensive. With the onset of advanced battery technology, lithium-ion UPS systems have become much more attractive due to reduced pricing that rivals most standard, lead-acid battery UPS systems. UPS systems feature a state-of-the-art lithium iron phosphate (Li...

  • Basic knowledge of filters

    Basic knowledge of filters

    Jun , 21 2023
    The Line filter is a filter circuit composed of capacitance, inductance and resistance. A filter can effectively filter out a specific frequency point in the power line or frequencies outside of that frequency point, obtaining a specific frequency power signal or eliminating a specific frequency power signal. A filter, as the name suggests, is a device that filters waves. Wave "is a very broad phy...

  • Lithium battery capacity loss cause analysis

    Lithium battery capacity loss cause analysis

    Jun , 21 2023
    Lithium-ion batteries are the fastest-developing secondary batteries after cadmium-nickel and nickel-hydrogen batteries. Its high-energy properties make its future look bright. However, lithium-ion batteries are not perfect, and their biggest problem is the stability of their charge-discharge cycle. This paper summarizes and analyzes the possible causes of capacity attenuation of Li-ion batteries,...

  • Selection of lead carbon-carbon addition

    Selection of lead carbon-carbon addition

    Jun , 30 2023
    The influence of chemical properties such as carbon material type and addition amount on battery performance was studied. Several different types of carbon materials (graphite, carbon black, activated carbon, etc.) were selected and tested for their effects on the negative electrode plate with additional amounts ranging from 0.2% to 4%, as well as hydrogen evolution inhibitors and adhesives. And c...

  • How to maintain and extend UPS battery life?

    How to maintain and extend UPS battery life?

    Jul , 10 2023
    UPS batteries are used for several different things, but their main design is to ensure equipment is covered during a power failure before any backup power can kick in. It ensures that there is no lapse in power and those certain types of machinery and equipment can stay up and running without any gaps. They are often used on computers or in data centers to ensure that no valuable information...

  • Industrial UPS with Ride-through Protection

    Industrial UPS with Ride-through Protection

    Jul , 28 2023
    Introduction Electrical utilities use reclosers on medium voltage supply to isolate faults caused by events such as lightning strikes, tree branches across lines, or animals making contact with live wires. The result of a recloser operation is a momentary power outage, lasting for up to a few seconds. These outages can cause an unplanned production stoppage which can be very costly. When momentary...

  • Effect of carbon black content on negative electrode performance of lead-acid battery

    Effect of carbon black content on negative electrode performance of lead-acid battery

    Aug , 04 2023
    VRLA battery is not ideal in electric vehicles because of its short life under deep charge and discharge cycle conditions. In recent years, with the improvement of positive plate grid materials, the cycle life of batteries has been improved, and the main reason for the failure of VRLA batteries for electric vehicles is the sulfation of the negative electrode. To this end, there are more studies on...
