How Can I Reduce Common Ups Battery Faults?
News 2023年4月23日 82
The service life of the ups depends on the natural environment of operation, the old state of maintenance and maintenance, and the enterprise mentality. Low efficiency, insufficient volume, poor software environment, high temperature, large dust, wet and cold will shorten the service life of the ups battery, and the service life of the ups will be reduced if the maintenance and maintenance is not timely.
ups switching power supply is suitable for maintenance-free batteries with a service life of 3-5 years. Some customers will use longevity model specifications, such as 8-10 years, up to 20 years. The ups battery life is also relatively long, reasonable use of monthly time and time discharge maintenance conditions can be used for 5-8 years, after the volume will be greatly reduced the need to consider replacing the ups switching power rechargeable battery.
How often do UPS batteries need to be replaced?
According to previous work experience, the ups battery is generally replaced once every five years to ensure its smooth and safe operation. For more extreme natural environment standards (e.g., operating temperatures usually exceed 35 degrees Celsius or human factors are not frequently maintained), it is recommended to replace the ups bottle within three years.
When the charging and discharging depth of the battery is 100%, the specific life of the battery is 100-200 charging and discharging cycles. For example, when the charging and discharging depth of the battery is 50%, the charging and discharging frequency of the battery can be increased to 300-400 times. When the charging and discharging depth of the battery is 30%, the charging and discharging frequency of the battery can be increased to 600 times. It is not difficult to see that, in order to improve the service life of the battery, rechargeable batteries are generally not allowed to be used in the case of deep charge and discharge.
How to reduce the ups power supply battery Common faults:
1. Regular maintenance
Maintain the DC voltage and internal resistance of each module. For 12V module rechargeable batteries, if the DC voltage difference of each module is greater than 80m or the internal resistance of each module is greater than 80m, balance the batteries to rectify the internal resistance of the rechargeable batteries and eliminate the DC voltage imbalance between the rechargeable batteries of each module. When the battery is charged, the battery is charged. Most rechargeable batteries have been solved by battery charging, and their internal resistance can be repaired to 30 meters. During the operation of the ascendant switch power supply, the imbalance of lithium batteries becomes more and more serious if off-line charging is not used immediately, because the characteristics of the rechargeable batteries in each module change over time, and the battery charging control circuit inside the ascendant switch power supply cannot eliminate the efficiency of the battery.
2. The main factor of lasting suitable working temperature is the working temperature, and the best working temperature is between 20 and 25℃. Although the temperature plus charge and discharge battery can have a certain driving force, but pay the value of the battery life is greatly shortened. According to the tests, once the operating temperature exceeds 25 degrees Celsius, the battery life limit needs to be cut in half for every 10 degrees Celsius. The batteries commonly used now are generally non-maintenance sealed lead-acid batteries, and the planned service life is generally five years, which is achieved in the battery manufacturer’s requirements for the natural environment. If you can’t meet the requirements of the natural environment, the length of life will be very different. In other cases, the operation of the operating temperature will lead to an increase in the organic chemical specificity within the rechargeable battery, and then a lot of energy will promote the surrounding operating temperature and this polarization, which will accelerate the reduction of battery life.
3. The floating working voltage and working voltage of the ascending switching power supply are adjusted to the rated current of the original factory rated current, while the charge-discharge current increases with the increase of the load. Generally speaking, the load is not suitable to cross the upper rating of 60%. In this scheme, the charge and discharge current is not easy to show excessive charge and discharge. In a natural environment, the power system is of high quality, the voltage is off, and the battery is always charged in a floating battery. Therefore, the normal charge and discharge once every 2-3 months, the charging and discharging moment can be judged according to the volume and load of the bottle. After one charge and discharge, the battery is charged for 8 hours.
4. Reduce deep discharges
The service cycle of electrotherapy is closely related to the depth of charge and discharge. The lighter the load required by the boost switch power supply, the larger the short-circuit capacity ratio between the storage capacity and the storage capacity when the voltage supply system terminates, and the deeper the charge-discharge battery is when the voltage of the boost switch power supply is too low. How to reduce rechargeable batteries by deep charging and discharging during the whole process? How to be very simple: When the ups switching power supply is at the end of a voltage powered system, most ups switching power supplies are based on the regular air gap 4s up and down alarm, notifying the user that the rechargeable battery has now proven the power supply. When the alarm sound becomes urgent, it shows that the switching power supply is in a state of deep charge and discharge, and the switching power supply should be turned off immediately. It is not urgent and generally does not have to let the switching power supply work until the battery voltage is too low and automatically switched.
5. Use the power system to charge peak-level batteries
In order to avoid battery failure caused by long-term battery charging, it is necessary to use the peak period of the power supply system (such as night time) to charge the battery in order to avoid battery failure caused by long-term low-voltage power supply system or frequent power outages, so as to ensure that the battery has enough charging time after charging and discharging. After deep charge and discharge, 90% of the battery must be recharged to short circuit capacity for at least 1012 hours. Note that the switch power maintenance sealed charging battery of the upper computer cannot be charged by the thyristor type quick charging battery. This is because the charging head will cause the battery to charge at instantaneous overcurrent and instantaneous overvoltage extreme battery charging. This condition greatly reduces the storage capacity of rechargeable batteries, which is made worse when the batteries are damaged. When the booster switch power supply is selected for the constant current source battery charging control loop, it is not necessary to adjust the voltage of the battery is too low. It should not be too low during maintenance. Otherwise, it is easy to cause overcurrent battery charging in the pre-charging stage of the battery. Of course, it is best to use a constant current and a constant current charging head to charge the battery.
6. The total number of weapon batteries for large, medium and small switching power supplies now ranges from 3 to 80, even large ones. This single rechargeable battery is composed of a lithium-ion battery through a power supply circuit to meet the requirements of the ups DC power system. In continuous working applications, due to the difference in function and quality, the function of single-charge batteries is reduced, and the storage capacity cannot meet the requirements and cannot be destroyed. When some rechargeable batteries in a lithium-ion battery pack are damaged, maintenance personnel should conduct an interrogation test on each rechargeable battery to remove the damaged rechargeable battery. When replacing a new rechargeable battery, we should seek to purchase the same rechargeable battery as the manufacturer, to prevent acid and alkali resistant rechargeable battery and sealed rechargeable battery, different standard rechargeable battery mixed application.
