      Correct Use of Storage Battery of Shante UPS Power Supply

      In the process of using UPS power supply system, people tend to unilaterally think that storage battery is maintenance-free and pay no attention to it. However, data show that the proportion of UPS mainframe failure or abnormal operation caused by battery failure is about 1/3. Therefore, it is more and more important to strengthen the correct use and maintenance of UPS batteries for prolonging the life of batteries and reducing the failure rate of UPS systems.

      How to use accumulator correctly in UPS power supply process

      In addition to the selection of regular brand batteries, the following aspects should be used and maintained correctly:

      1. Maintaining an Appropriate Environmental Temperature

      Environmental temperature is an important factor affecting the life of batteries. The optimal ambient temperature required by battery manufacturers is 20 - 25 C. Although the discharge capacity of batteries is improved with the increase of temperature, the cost is that the life of batteries is greatly shortened. According to the test results, once the ambient temperature exceeds 25 C, the battery life will be reduced by half for every 10 C increase. At present, UPS batteries are generally maintenance-free sealed lead-acid batteries. Their design life is generally five years, which can be achieved only under the environment required by battery manufacturers. If it fails to meet the required environmental requirements, its life span will vary greatly. In addition, the increase of ambient temperature will lead to the increase of chemical activity inside the battery, which will generate a lot of heat energy, and in turn will promote the increase of ambient temperature. This vicious cycle will accelerate the shortening of battery life.

      2. Regular charging and discharging

      The floating charge voltage and discharge voltage in UPS power supply have been adjusted to the rated value at the time of leaving the factory. The discharge current increases with the increase of the load. The load should be adjusted reasonably in use, such as controlling the number of electronic devices such as microcomputers. Normally, the load should not exceed 60% of the UPS rated load. Within this range, there will be no excessive discharge in the discharge current of the battery.

      Because UPS is connected with municipal electricity for a long time, in the environment of high quality power supply and few blackouts, the storage battery will be in a floating charging state for a long time, which will lead to the reduction of the activity of the conversion between chemical energy and electric energy, accelerate aging and shorten the service life of the battery. Therefore, the discharge should be completed every 2-3 months, and the discharge time can be determined according to the capacity and load size of the battery. After a full-load discharge is completed, the charge shall be recharged for more than 8 hours according to the regulations.

      3. Utilizing Communication Functions

      At present, the vast majority of large and medium-sized UPS have the operability of communication with microcomputers and program control. The corresponding software is installed on the computer, and UPS is connected through serial/parallel ports. By running the program, the computer can communicate with UPS. Generally, it has the functions of information inquiry, parameter setting, timing setting, automatic shutdown and alarm. Through information inquiry, information such as input voltage, UPS output voltage, load utilization ratio, battery capacity utilization ratio, in-machine temperature and power frequency can be obtained. Through parameter setting, basic characteristics of UPS, battery maintenance time and battery exhaustion alarm can be set. Through these intelligent operations, it greatly facilitates the use and management of UPS power supply and its batteries.

      4. Replacing Waste/Battery in Time

      At present, the number of batteries equipped with large and medium UPS power supply varies from 3 to 80, or even more. These individual batteries are connected by a circuit to form a battery pack to meet the needs of UPS DC power supply. In the continuous operation and use of UPS, due to the difference in performance and quality, the performance of individual batteries is degraded and the storage capacity is not up to the requirements, and damage is inevitable. When one or more batteries in the battery pack are damaged, maintenance personnel should check and test each batteries to eliminate damaged batteries. When replacing new batteries, we should strive to purchase the same type of batteries with the same manufacturer. It is forbidden to mix acid-proof batteries with sealed batteries and batteries of different specifications.
