  • Test, use and maintenance of battery for UPS uninterruptible power supply

    Test, use and maintenance of battery for UPS uninterruptible power supply

    Mar , 30 2024
    UPS battery occupies a very important position in UPS power supply equipment. At present, the maintenance-free sealed lead-acid battery widely used in small and medium-sized UPS power supplies accounts for as much as 1/4 to 1/2 of the total cost of UPS power supplies. Not only that, the actual maintenance also shows that more than 50% of UPS power failures are related to UPS batteries. Regardless ...

  • Effect of low temperature on battery performance

    Effect of low temperature on battery performance

    Mar , 30 2024
    When the lithium-ion battery is in a low temperature state, its available capacity is reduced and the charge and discharge power is limited. If the power is not limited, it will cause the evolution of lithium ions inside the battery, which will lead to irreversible attenuation of the battery capacity, and will bury a safety hazard for the use of the battery. The lower the ambient temperature, the ...

  • Long-term storage methods for lithium batteries and storage requirements for lithium iron phosphate batteries

    Long-term storage methods for lithium batteries and storage requirements for lithium iron phosphate batteries

    Apr , 20 2024
    What impact will the lithium battery have after being put aside for a long time? When the lithium battery is idle, due to the nature of the battery itself, self-discharge, passivation of positive and negative electrode materials, electrolyte decomposition and other phenomena will occur. The instability of the negative SEI will lead to the rapid decline of the negative active substance, which is ea...

  • What is the impact of low temperature on lithium batteries and solutions

    What is the impact of low temperature on lithium batteries and solutions

    Apr , 20 2024
    The use of lithium batteries in low battery temperature environments is limited. In addition to a severe drop in discharge capacity, lithium batteries cannot be charged when the battery temperature is low. When the battery is charged at low temperature, the lithium ion embedment on the battery graphite electrode and the lithium plating reaction exist simultaneously and compete with each other. Und...

  • The difference and comparison of advantages between P-type and N-type components

    The difference and comparison of advantages between P-type and N-type components

    May , 11 2024
    Materials and Structure of a Solar Cell The construction of a particular solar cell is going to vary slightly depending on the specific technology that is utilized to manufacture it. In most solar cells, there is an aluminum back surface field and a P-N Junction. At the P-N junction, there are p-type crystalline silicon wafers that are positively charged and n-type crystalline silicon wafers that ...

  • Industrial and commercial energy storage system liquid cooling design

    Industrial and commercial energy storage system liquid cooling design

    Jun , 14 2024
    1. Industrial and commercial energy storage system liquid cooling design For the high-rate charging and discharging process of large-scale battery packs, the cooling capacity of air cooling system can not meet the heat dissipation demand of battery packs. Liquid has a higher specific heat capacity and higher thermal conductivity than air, and the liquid cooling cooling speed is faster, which has a...

  • Maximum power point tracking algorithm for photovoltaic power generation

    Maximum power point tracking algorithm for photovoltaic power generation

    Jun , 22 2024
    1. Introduction Photovoltaic power generation is a technology that uses solar energy to convert light energy into electricity. In the photovoltaic power generation system, in order to obtain the maximum power generation power, it is necessary to track the change of solar radiation intensity in real time, and adjust the working state of the photovoltaic module to keep near the maximum power point. ...

  • Five things that shorten the life of your UPS battery

    Five things that shorten the life of your UPS battery

    Jun , 26 2024
    One of the more common questions we get asked is how long a UPS battery will last. The ballpark, general answer is 3 to 5 years; however that answer is generallyl. And that’s because the life of your battery depends on a whole host of factors. Those factors are what we’re going to discuss today. Here are some of the things that can shorten the lifespan of your UPS battery. Let’s jump right in. Amb...
