[0004] 2. The checking discharge test requires discharging 30%-40% of the rated capacity, which is usually implemented online. Therefore, for communication loads where the load is particularly important, if the overall deterioration is serious or the reverse pole of a single unit cannot be detected and rectified in time, discharge There are certain security risks in testing
[0005] 3. The maintenance regulations require that the battery pack should do a checking discharge test every year, a capacity test once every three years, and once a year after six years of use. The test time span is long, and the timeliness of finding battery faults through the discharge test is not high enough.

The invention discloses a battery pack reverse pole single battery detection method and system, and relates to the technical field of battery maintenance in a communication system. The method comprises the steps that the balanced charging data of a battery pack are acquired, wherein the balanced charging data of the battery pack comprise the voltage of the battery pack and the voltage of each single battery; the voltage of each single battery is normalized; the reference voltage value of each single battery is determined according to a cluster analysis algorithm; the deviation value of the normalized voltage of each single battery and the reference voltage value is calculated; and the deviation value of each battery is cross-calculated to determine a reverse pole single battery in the battery pack. According to the invention, the performance of the battery pack is determined without discharge; a faulty single battery is found in time; important information is provided for online evaluation of the health condition of the battery pack and timely battery update, so that the battery pack can be in a stable and stable running state; and safe operation of electrical equipment is ensured.
Description
technical field [0001] The invention relates to the technical field of storage battery maintenance in a communication system, in particular to a detection method and system for a single cell with reverse polarity in a battery pack. Background technique [0002] The reverse polarity of the single battery of the battery pack is a phenomenon of serious deterioration and failure of the battery, which will cause the battery pack to fail to discharge current for power supply normally, and cause downtime or even paralysis of the communication system in the communication industry. Therefore, in order to ensure the safety of the power supply of the backup battery system, the communication industry checks the capacity of the battery through the verification of the battery pack or deep discharge. This is the most effective way to evaluate the performance of the battery and detect the reverse polarity of the single battery. In the prior art, it is possible to preliminarily judge whether...
