Analysis of the traditional UPS battery test maintenance methods and its disadvantages

Source: 2020 - 04 - 12 clicks use: traditional UPS battery test and maintenance methods and its disadvantages of UPS battery test and maintenance methods have been the constant development and progress. When the battery is just put into use, it formed the traditional test and maintenance methods. However, these methods are too primitive, cannot meet the needs of the contemporary. The traditional battery voltage of the measuring method is first measured with a multimeter. After a long practice, we found that using the multimeter test methods for the judgment of old batteries has lost the desired effect, and can't effectively respond to all aspects of the battery performance. Another way is to test whether or not the UPS power supply at boot time to the standards set by the output current. But the disadvantage of this test is not completely determine the quality of the battery, because some of the battery to discharge if long-term storage or irregularly there may be a lack of instantaneous current. In addition, UPS battery capacity of judgment, the traditional test method and judgment of the common type of battery is the same, after the battery pack to cut off the power supply connection resistance wire, through the first to arrive terminal power calculation of battery capacity and time of arrival, but the traditional test methods can't make up a series of shortcomings, such as when the test, if the battery power will largely increase the risk of collapse. Moreover, when using this method for testing, discharge time is often very long, in the case of manual records, workload will increase unconsciously. In addition, the resistance wire heating red hot phenomenon would appear, danger index also rose sharply.
