  • 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...

  • The difference between the first, second, and third levels of distribution boxes

    The difference between the first, second, and third levels of distribution boxes

    Jun , 22 2024
    What do the primary, secondary, and tertiary boxes of a distribution box mean? This is a relative issue. Let's make a hypothesis: a newly built residential area introduces a 10kV incoming line and builds a distribution room. The outgoing line from the low-voltage end of the transformer is 0.4kV to the distribution cabinet (primary distribution cabinet), then the outgoing line is led to the distrib...

  • 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...

    Explanation of terms related to UPS power supply

    Jul , 06 2024
    Transient Recovery Time: The time it takes for the output voltage to return to the specified range when there is a sudden change in load (0‐100%, 100%‐0), usually on the order of seconds (ms). Filter: a device used to eliminate noise, the input or output filtered to obtain a pure contention of the alternating current. Shielding: The use of physical principles, used to isolate the electromagnetic r...

  • What is the meaning of float charging for intelligent three‐stage charger in battery charger?

    What is the meaning of float charging for intelligent three‐stage charger in battery charger?

    Jul , 12 2024
    Float charging: Keep constant voltage charging, the charging current continues to decrease, and the battery is charged with maintenance type. When the charging current decreases to the set value or the charging time reaches the set value, the red light of sufficiency will be on, and the time will be about 2H, charging 10% of the power. Ordinary chargers are old‐fashioned chargers, charging, whethe...

  • How to extend the power supply time of uninterruptible power supply (UPS)

    How to extend the power supply time of uninterruptible power supply (UPS)

    Aug , 03 2024
    There are two ways to extend the duration of an uninterruptible power supply： 1. Increase battery capacity. According to the length of time required to increase the number of batteries, but this method will cause a relative increase in battery charging time, but also increase the number of corresponding maintenance equipment, increase product size, resulting in an increase in the overall cost of U...

  • Four operating modes of UPS

    Four operating modes of UPS

    Aug , 23 2024
    1、Normal operation mode The principle of the power supply system is that when the utility power is normal, the machine will convert the alternating current of the utility power to direct current, and then charge the battery for use when the power is interrupted; it is emphasized here that the power supply system will not only act when the power is out, such as when the voltage is too low or high, ...
