Embodiment 1

[0024] Embodiment 1: A method for maintaining the online capacity of a communication power storage battery, the specific steps of which are:

[0025] a. For the base station in normal operating state, cut off the AC power supply, and use the storage battery to independently supply power to the control cabinet, and use the storage capacity detector of the storage battery to detect the load voltage value U of the battery one by one. F , and record that the voltage value displayed by the control cabinet should be continuously observed during the test, and the measurement should be stopped immediately when it is lower than 46.5V;

[0026] b. Put the load voltage value U F Replace the battery below the safe use standard to ensure the balance of battery pack capacity;

[0027] c. After adding water to the plate height, add 500mL / 500Ah. Every time you check the battery, the liquid level should be roughly kept at this height;

[0028] d. For battery packs with a reserved capacity of...

Embodiment 2

[0030] Embodiment 2: The online capacity maintenance method of the communication power battery of the present invention is the same as that of Embodiment 1, and the similarities will not be repeated. The difference is that when the communication power battery adopts the 12U conjoined battery in the UPS power supply, the conjoined battery should be used The battery tester detects its actual power supply capacity.

Abstract

Using detector for retaining capacity of accumulator, the method detects value of load voltage for batteries one by one when base station is in operation state. The method includes steps: observing value of voltage displayed continuously, when detecting; when the voltage displayed lower than 46.5V, stopping measuring instantly; replacing batteries with value of load voltage being lower than standard of safe use; after supplying water to height of polar plate, reentering 500mL / 500Ah; when checking-up batteries each time, keeping liquid level at this height; carrying out operation of electronic sulphur elimination for accumulator set with retaining capacity being lower than 60%; based on retaining capacity to adjust floating charged voltage to 54-56V, and specific voltage value determined according to measurement. The invention makes time of safe using batteries reach to more than eight years. The standard of safe use is that structural capacity is not lower than 80%.

Description

1. Technical field: [0001] The invention relates to a storage battery maintenance method, in particular to an online capacity maintenance method of a communication power storage battery. 2. Background technology: [0002] The sealed battery used by the communication department is widely used as a backup power source for communication base stations, but due to improper maintenance, the battery damage rate is very high. The current statistical life is that when it is used for about 3 years, the structural capacity will drop below 80%. The structural capacity refers to the actual capacity of the battery after it is fully charged. During the use of the battery, the structural capacity of the battery undergoes a hump process of "first rising and then falling". The shape of the hump depends on the manufacturing process and use conditions, and the structural capacity is low. Due to the use of standards, the reserved capacity of the battery will be low, which is one of the reasons f...
