Embodiment 1

[0030] The present invention provides an embodiment, such as figure 1 A maintenance method for a battery backup unit shown includes the following steps:

[0031] Step 1: Read the current power value of the battery backup unit.

[0032] Step 2: Determine whether the battery backup unit is fully charged according to the current power value, if yes, go to step 4, if not, go to step 3.

[0033] Step 3: Charge the battery backup unit, and enter the rest state after charging after being fully charged.

[0034] The purpose of the above steps is to ensure that the battery backup unit is in a fully charged state, as a reference point for power calibration, and to ensure the accuracy of capacity estimation in subsequent discharge tests.

[0035] Step 4: Discharge the battery backup unit to a preset power value, and obtain an estimated capacity of the battery backup unit according to the discharge voltage and discharge current during the discharge process.

[0036] It should be noted ...

Embodiment 2

[0038] The present invention provides another embodiment, such as figure 2 A maintenance method for a battery backup unit shown includes the following steps:

[0039] Step 1: Read the current power value of the battery backup unit.

[0040] Step 2: Determine whether the battery backup unit is fully charged according to the current power value, if yes, go to step 4, if not, go to step 3.

[0041] Step 3: Charge the battery backup unit, and enter the rest state after charging after being fully charged.

[0042] Step 4: Discharge the battery backup unit to a preset power value, and obtain an estimated capacity of the battery backup unit according to the discharge voltage and discharge current during the discharge process.

[0043] Step 5: Charge the battery backup unit, and update the estimated capacity after it is fully charged.

[0044] On the basis of step 4, fully charge the battery backup unit and update the estimated capacity, so that the power of the battery backup uni...

Embodiment 3

[0048] The present invention provides another embodiment, such as image 3 A maintenance method for a battery backup unit shown includes the following steps:

[0049] Step 1: Read the current power value of the battery backup unit.

[0050] Step 2: Determine whether the battery backup unit is fully charged according to the current power value, if yes, go to step 4, if not, go to step 3.

[0051] Step 3: Charge the battery backup unit, and enter the rest state after charging after being fully charged.

[0052] Step 4: Discharge the battery backup unit to 73.5%, obtain the estimated capacity of the battery backup unit according to the discharge voltage and discharge current during the discharge process, and enter the rest state after discharge.

[0053] Step 5: Continue to discharge the battery backup unit to 50%, and update the estimated capacity according to the discharge voltage and discharge current during the discharge process.

[0054] After the battery backup unit is f...

Abstract

The invention discloses a battery backup unit maintenance method. Multiple times of charging and discharging actions are carried out on the battery backup unit, the estimated capacity is updated aftercompletion of each charging and discharging, the estimated capacity when the battery backup unit is in a fully-charged state is compared with a theoretical fully-charged capacity, and if the error isin a preset difference range, the maintenance succeeds. The method can be realized in a script mode in a micro-system, the power of the battery backup unit can be calibrated automatically, the powerstorage ability of the battery backup unit is ensured to be constantly in a health state, and when a storage node is power-off suddenly in a working environment, the battery backup unit can perform timely power supply, normal operation of storage equipment is ensured, and data safety is further ensured.

Description

technical field [0001] The invention relates to the technical field of storage devices, and more specifically relates to a method for overhauling a battery backup unit. Background technique [0002] With the rapid development of data storage technology, data storage devices are more and more widely used, and people pay more and more attention to data security. Storage devices usually require a normal and stable power supply to ensure the normal operation of the device. Therefore, in storage devices including computers, in addition to the main power supply for providing electrical energy to the device, a battery backup unit (battery backup unit) is usually provided. unit) referred to as BBU, to start the battery backup unit to ensure the normal operation of the equipment when the main power supply fails. [0003] The battery backup unit is usually connected to the storage node, and immediately supplies power to the storage node when the storage node is powered off, so that t...
