| Santak UPS power battery maintenance method |
| Time：2017-04-17 Source： Views：4466 |
Many people think that the battery is not needed to maintain, especially in the use of UPS power supply, this idea is even more obvious. But in fact, due to the lack of maintenance of the battery caused by the problem in the UPS accounted for a high proportion of all faults. Therefore, the routine maintenance of the UPS battery will greatly extend the battery life and reduce the failure rate of UPS. This article will introduce the maintenance of UPS battery.
Maintain appropriate ambient temperature
Generally speaking, the factors that affect the battery life are the environmental temperature. The best ambient temperature required by a battery manufacturer is between 20-25 and C. Although the rise of the temperature of the battery discharge capacity has increased, but the price is to pay the battery life is greatly shortened. According to the test, once the ambient temperature exceeds 25 degrees, every increase of 10 degrees, the battery life will be shortened by half. At present, the storage battery used in UPS is generally free of maintenance, and the design life is generally 5 years. Can not meet the requirements of the environment, there is a great difference in the length of its life. In addition, the environmental temperature increased, will lead to enhanced chemical activity inside the cell, resulting in a lot of heat, in turn to the ambient temperature rises, the vicious spiral, will shorten the battery life.
Periodic charge discharge
UPS power supply of the floating charge voltage and discharge voltage, at the factory have been adjusted to the rated value, and the discharge current is increased with the increase of load, load regulation should be reasonable use, such as the control of computer and other electronic equipment using units. In general, the load should not exceed UPS rated load of 60%. in this range, the battery discharge current will not appear excessive discharge.
UPS for a long time and power is connected in the power supply of high quality, rare power cut operating environment, the battery charging state in a long term, a long time will cause the battery chemical energy conversion decreased activity, accelerated aging and shorten the service life. Therefore, the general should be completely discharged every 2-3 months, the discharge time can be determined according to the battery capacity and load size. After the completion of a full load discharge, according to the provisions of charging more than 8 hours.
Use communication function
At present, the vast majority of large and medium-sized UPS with microcomputer communication and program control and other operational performance. On the computer to install the appropriate software, through the serial / parallel connection UPS, run the program, you can use the computer and UPS communication. General information query, parameter settings, timing settings, automatic shutdown and alarm functions. Through the information query, can obtain the power input voltage, UPS output voltage, load utilization, battery capacity utilization rate, the temperature inside the machine and power frequency information; by setting the parameters, you can set the UPS battery can maintain the basic characteristics, time and battery alarm etc.. Through these intelligent operation, greatly facilitate the use of UPS power supply and battery management.
Timely replacement of waste / bad battery
At present, large and medium-sized UPS power supply with the number of batteries, ranging from 3 to only 80, or even more. These individual cells are connected by a circuit to form a battery pack to meet the needs of UPS DC power supply. In the continuous operation of the use of UPS, due to the difference in performance and quality, the performance of individual batteries, storage capacity is not up to the requirements and damage is inevitable. When one or more of the batteries in the battery pack is damaged, the maintenance personnel shall inspect and test each battery to remove damaged batteries. The replacement of the battery, should try to buy the same manufacturer with type of battery, battery and battery, prohibit acid of different specifications of the batteries.
This article provides four methods to prolong the working life of UPS battery, in general can be summed up in four words: appropriate temperature, charge and discharge, the regular use of communication function, timely replacement of damaged battery. In the study of the power of the university did not ask or primary school, as long as attention to observation, we can sum up a variety of features and methods to facilitate our design.
