In the era of big data, higher requirements are put forward for the reliability and intelligent control of storage systems, especially the power supply stability of storage systems. Under normal circumstances, the storage system is powered by the power supply. When the power supply cannot provide power, it will switch to The backup power module provides power. Therefore, it is very important to ensure that the backup power module can operate normally. The backup power module consists of a backup battery unit (Backup Battery Unit, BBU) and a BBU control module. Under normal circumstances, in order to manage the backup power module, the BBU of the backup power module will be equipped with a battery management system (Battery Management System, BMS). Its main function is to intelligently manage and maintain each battery unit of the backup power module to prevent battery failure.

When the storage system cannot use the power supply for power supply, it will switch to the backup power module for power supply. However, The BBU, BBU control module, storage system, and the charging link and discharge link used for connection may all fail. Therefore, it is necessary to find these faults and perform fault repairs on the entire system based on the location of the fault. The power backup capability in the backup power module gradually decays. Therefore, the power supply switching process of the storage system can be simulated at regular intervals to evaluate the power backup capability of the backup power module to find hidden dangers in the system and avoid the need for When the backup power module supplies power, if the backup power module fails and fails to provide power, an evaluation can generally be conducted every three months.

When these values are close to the alarm threshold of the BMS, alarm processing will be performed to find the hidden dangers of the BBU in advance and avoid them. The storage system loses data and improves the power supply stability of the storage system. The BBU power supply link detection circuit can be used to monitor the voltage, current, and power values of the power supply link. The TI INA219A intelligent monitoring chip can be used as the control chip of the BBU power supply link detection circuit.
