Remote discharging control system, monitoring unit device and detecting method of storage battery pack

Abstract

The invention discloses a remote discharging control system, a monitoring unit device and a detecting method of a storage battery pack. The detecting method comprises the steps of: in the discharging process of the storage battery pack, collecting a monomer voltage, a total voltage, a discharging current and a marked temperature of the storage battery pack so as to draw a discharging curve; calculating a capacity discharged by the storage battery pack under the current marked temperature in real time, and converting the capacity value into the capacity value under a reference temperature; comparing the discharging curve with a historic discharging curve drawn under the same load so as to update an aging ratio of the storage battery pack in real time; and calculating an actual total capacity of the storage battery pack at the beginning of the test when the discharging is finished, and obtaining the needed detecting data according to the actual total capacity, the discharging curve and the discharged capacity information. By adopting the method, the remote discharging test can be performed; the testing data of the storage battery pack can be rapidly inquired; the aging problem of the storage battery pack is solved; and the estimation accuracy is improved.

Description

technical field [0001] The invention relates to the communication field, in particular to a remote discharge control system for a storage battery, a monitoring unit device for a storage battery and an online detection method for a storage battery. Background technique [0002] As the backup power supply system of base stations and computer rooms in the communication industry, the battery pack plays a very important role, which ensures the uninterrupted work of communication equipment. Therefore, it is of great significance to monitor and maintain the battery pack to ensure the reliability of the entire communication system. [0003] The management and maintenance of the storage battery is very time-consuming and laborious. If the storage battery is not well maintained, it will often enter the scrapping period ahead of time. At present, the maintenance of batteries requires maintenance personnel to go to the site to conduct discharge tests and detect faulty batteries, which ...

AI Technical Summary

Problems solved by technology

This method first needs to obtain a large amount of curve data for storage, and the data acquisition is complicated; the estimation by interpolation method is based on the selected discharge curve, which itself has a large error

In addition, since the patent does not consider the aging of the battery, the error of the measured data will increase with the increase of the service life of the battery.
