Shengyang Battery Configuration Up Power Supply Maintenance and Charging and Discharging

Adhere to the appropriate ambient temperature

_Generally speaking, the environmental temperature is the key factor affecting the battery life. The optimum ambient temperature requested by ordinary battery manufacturers is between 20 and 25 degrees Celsius. Although the increase of temperature can improve the battery discharge, the cost is that the battery life is greatly shortened. According to the experimental 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. The design life of UPS batteries is generally five years, which can only be reached in the environment requested by battery manufacturers. If the environmental requirements of the rules are not met, the life span will vary greatly. In addition, the progress of ambient temperature will lead to the enhancement of chemical activity inside the battery, which will generate a lot of heat energy, and in turn will promote the increase of ambient temperature around the battery. This vicious cycle will accelerate the shortening of battery life.

_Shengyang battery periodically charged and discharged

The floating charge voltage and discharge voltage in UPS power supply have been debugged to the rated value at the time of leaving the factory, and the discharge current increases with the increase of the load. The load should be adjusted reasonably in operation, 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, the discharge current of the battery will not show excessive discharge.

_UPS is connected with municipal electricity for a long time. In the application environment of high quality power supply and few blackouts, the storage battery will be in floating charging state for a long time. Over time, the activity of chemical energy and electric energy conversion will be reduced, and the service life will be shortened due to accelerated aging. 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, recharge more than 8 hours according to the rules.

_Application Communication Function of Shengyang Battery

At present, the vast majority of large and medium-sized UPS have the operability of communication with microcomputers and program control. By installing the corresponding software on the computer and connecting UPS through serial/parallel ports and running the program, the communication between the computer and UPS can be stopped. Usually it has functions of information inquiry, parameter setting, timing setting, automatic shutdown and alarm. Through information inquiry, information such as input voltage, UPS output voltage, load application rate, battery capacity application rate, in-machine temperature and power frequency can be obtained; after parameter setting, UPS basic characteristics, battery maintainability time and battery exhaustion alarm can be set. Through these intellectualized operations, UPS power supply and its Shengyang battery management are greatly facilitated.

Change Waste/Battery in Time

At present, the number of batteries in large and medium UPS power supply equipment varies from 3 to 80, and even more. These individual batteries are connected by circuit to form battery packs to meet the demand of UPS DC power supply. In the intermittent operation of UPS, due to the difference in performance and quality, it is unavoidable that the performance of individual batteries will drop and the storage capacity will not reach the request. When one or more batteries in the battery pack are damaged, maintenance personnel should stop checking and testing each batteries and clean up the damaged batteries. When replacing new batteries, efforts should be made to purchase batteries of the same type as those produced by the same manufacturer, and to prevent the mixed use of acid-proof batteries, sealed batteries and batteries of different specifications.
