Method and system for judging storage battery capacity and health

Abstract

The invention discloses a method and system for judging storage battery capacity and health, including determining capacity based on conductance test value of the battery. Conductance test adopts special instrument, conductance of each monomer battery is tested, the actual conductance and capacity of massive batteries in different types and different residual capacity are tested, correspondence distribution therein is obtained by statistics, according correspondence astringency is found, so as to obtain the correspondence of conductance and capacity of the battery of the type, and software is required to calculate astringency and distribution relation on massive detection data, and applicability of the rule thereof is improved along with increase of data to be tested, thus improving accuracy of judging. Besides, the judging only can determine the range of the capacity of the monomer battery instead of correcting to concrete capacity value. The invention has the application value in actual maintenance that time and work load for judging the range of capacity of battery are greatly reduced, the batter is not required to be charged or discharged, and no threat is produced to the operation safety of battery in the existing network.

Description

technical field [0001] The invention relates to the field of battery maintenance and capacity detection, in particular to a method for judging the battery capacity and health degree of a backup power supply of a communication base station computer room and a related system. Background technique [0002] At present, lead-acid batteries are widely used in the communication industry as a backup power supply when the mains power is interrupted. Therefore, in order to ensure smooth communication during power outages and ensure social security, the daily maintenance and management of lead-acid batteries is one of the key tasks in the maintenance work of all communication operators. [0003] An existing maintenance method for a lead-acid battery is to perform a full-capacity discharge test. This method accurately tests the capacity of the battery pack by connecting a dummy load and discharging the battery pack with a constant current. However, this method takes a long time, the in...

Problems solved by technology

Although the full-capacity discharge method can accurately reflect the current capacity level of the battery pack and obtain the exact condition of the worst battery or batteries, it does not accurately know the condition and life of each battery cell in the group.

[0005] The service life of the domestic storage battery refers to the service life under the floating charge state, but under the condition of unstable domestic power supply, the battery is repeatedly in the state of charging and discharging, and the service life decays quickly; this situation makes the full capacity once a year The discharge test density still cannot detect the battery decline in time; moreover, the information obtained from the current full-capacity discharge test is scattered, which requires a lot of practice and energy of the maintenance personnel. Further increasing the discharge test density will make the b
