Four methods of UPS battery maintenance

Many people think that it is not need to maintain battery, especially when using UPS power supply, this idea is more obvious. But in fact, due to lack of maintenance battery problem in all UPS fault is quite high in proportion. So, to maintain the UPS battery routine, will be largely prolong the UPS battery life and reduce the failure rate. This article will introduce UPS battery maintenance methods. Maintain a comfortable environment temperature in general, major factors affecting the service life of the battery is the environment temperature. General battery manufacturer requirements in 20 - is the best environment temperature Between 25 ℃. Although the rise of temperature of the battery discharge ability improved, but the cost is greatly shorten the life of a battery. According to the test, once more than 25 ℃, environment temperature rise every 10 ℃, the battery life will shorten the half. The current UPS battery is commonly used in the maintenance-free sealed lead-acid battery, design life is generally 5 years, in the environment to achieve the required by the battery manufacturer. Can not meet the environmental requirements, the length of its life is a big difference. In addition, the improvement of the environment temperature, will cause the battery internal chemical activity enhanced, resulting in a large amount of heat energy, will in turn lead to ambient temperature, this kind of vicious circle, will accelerate to shorten the battery life. Regular charge discharge UPS power of float charging voltage and discharge voltage, when the factory have been debugging to the rating, and the size of the discharge current is increased with the increase of load, in use should be reasonable to adjust load, control the use of the computer and other electronic equipment such as the Numbers. In general, load should not be more than 60% of the rated load UPS. In this range, the discharge current of the battery will not appear excessive discharge. UPS for long-term are connected to the mains, rarely occur in high quality of power supply, the use environment of mains power failure, the battery will float charging status for a long time, long battery will lead to chemical energy and electrical energy conversion activity, accelerated ageing, shorten service life. Therefore, every 2 - general 3 months should be completely discharge time, discharge time can be determined according to the capacity of the battery and load size. After the completion of a full load discharge, in accordance with the provisions, to charge more than 8 hours. Use communication function at present, most large and medium-sized UPS with computer communication and process control and other operational performance. Install the corresponding software on microcomputer, through the series/parallel connection UPS, run the program, you can use to communicate with the microcomputer with UPS. General information query, parameter setting, time setting, automatic shutdown and alarm, etc. Through the information query, can obtain the utility utilization rate of the input voltage, output voltage, load UPS, battery capacity utilization, machines, such as temperature and mains frequency information; Through the parameter Settings, can be set UPS basic features, battery and battery run out of time the alarm, etc. Through these intelligent operation, greatly facilitate the use of UPS power supply and battery management. Timely replacement of scrap/bad battery number is large and medium-sized UPS power supply with battery, ranging from three to 80, and more. These single battery connection electric circuit constitute battery pack, in order to meet the needs of the dc UPS power supply. In the operation of the UPS continuous use, because of differences in performance and quality, individual battery performance degradation, storage capacity can not meet the requirement and the damage is inevitable. When the batteries in a certain/some damage to the battery, the maintenance personnel shall be inspection on each battery test, ruled out the damaged cells. Replacing new battery, should strive to purchase with the manufacturers of the same model battery, ban acid battery and mixed sealed battery, different specifications of the battery. This article presents the four methods to prolong the working life of the UPS battery, in general can be summed up in four words: the right temperature, charging and discharging regularly, make good use of communication function, timely replacement of damaged cells. There is no university in the power of learning q q or elementary school, as long as the watch, can be summed up all kinds of characteristics and methods, convenient our design.
