In the process of using the uninterrupted power supply system, people tend to think that the battery is maintenance free and not attached to the system. However, data show that the battery failure caused by the UPS host failure or abnormal operation of the ratio is about 1/3. Therefore, to strengthen the correct use and maintenance of UPS battery, to extend the battery life, reduce the failure rate of UPS system, has a more and more important significance. In addition to the regular brand batteries, the following aspects should be used to correctly use and maintain the battery:
One, maintain appropriate environment temperature. An important factor affecting the life of the battery is the ambient temperature, the general battery manufacturers require the best environmental temperature is between 20-25. Although the increase in the temperature of the battery discharge capacity has increased, but the price is the battery life is greatly reduced. According to the test, the environmental temperature once more than 25 degrees, every 10 degrees Celsius, the battery life will be shortened by half. At present, the battery is generally used in UPS maintenance free sealed lead-acid batteries, design life is generally 5 years, which in the battery manufacturer to achieve the requirements of the environment. Can not reach the requirements of the environment, the length of its life there is a great difference. 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.
Two, regular 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. Under normal circumstances, the load should not exceed 60% of the rated load of UPS. In this range, the discharge current of the battery will not be 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, in general every 2-3 months should be a full discharge, discharge time can be determined according to the capacity of the battery and load size. After a full load discharge, according to the provisions of charging more than 8 hours.
Three, the use of communication functions. At present, the vast majority of large and medium-sized UPS are equipped with computer communication and program control and other operational performance. Install software on computer through the serial / parallel connection UPS, run the program, you can use the computer to communicate with the UPS. 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 operations, greatly facilitate the use of UPS power supply and battery management.
Four, in a timely manner to replace the waste / bad battery. At present, large and medium-sized UPS power supply is equipped with the number of batteries, ranging from 3 to 80, or even more. These individual cells are connected by a circuit to form a battery pack to meet the needs of the UPS DC power supply. In the use of UPS continuous operation, due to the performance and quality of the difference, the performance of individual cells decreased, the storage capacity of less than the requirements and damage is inevitable. When a certain / some battery in the battery pack is damaged, the maintenance personnel shall inspect and test each battery. 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.
