Embodiment 2

[0099] Based on the same inventive concept, the present invention also provides a backup method, which can be applied to Figure 1-Figure 5 The illustrated embodiment shows a backup power supply, such as Figure 6 shown, including:

[0100] S601, collecting an input voltage for charging the energy storage medium;

[0101] S602, judging whether the server is powered off according to the input voltage;

[0102] S603. When it is determined that the power is not lost, perform a power storage operation on the energy storage medium, and when it is determined that the power is lost, perform a discharge operation on the external device through the energy storage medium.

[0103] In an optional implementation manner, before collecting the input voltage for charging the energy storage medium, it further includes:

[0104] Control the power supply input and output control module between the first port and the second port to be in a conduction state, so that the first power supply stor...

Abstract

The present invention relates to the technical field of power supplies, in particular to a backup power supply and a backup method. The backup power supply includes: a power supply input and output control module, including a first port, a second port and an input voltage acquisition module. The first port is connected to an external device, and the input The voltage acquisition module is arranged between the second port and the charge and discharge management module, and is used to collect the input voltage for charging the energy storage medium, and transmit the collected input voltage to the charge and discharge management module; the charge and discharge management module uses Based on the input voltage, it is judged whether the server is powered off. When it is determined that the power is not lost, the energy storage medium is stored. When it is determined that the power is lost, the external device is discharged through the energy storage medium. A power supply end; energy storage medium, connected to the charge and discharge management module, so as to ensure that the data to be protected is switched to the energy storage medium of the backup power supply without damage when the power supply end of the external device is powered off, ensuring data security.

Description

technical field [0001] The invention relates to the technical field of power supplies, in particular to a backup power supply and a backup method. Background technique [0002] A Non-Volatile Dual Inline Memory Module (NVDIMM) is a type of random access memory used in computers that is memory capable of retaining its contents even when power is removed, so in Dual Inline Memory Module ( DIMM) can protect the data of the memory module. [0003] However, when the power supply of the NVDIMM server system is abnormal, it needs to be powered by a backup power supply to ensure that the data in the NVDIMM is protected. [0004] At present, the energy storage module of the backup power supply generally adopts a method of physically separating the charging path and the discharging path, which leads to complex interfaces. [0005] Therefore, how to change the isolation mode of the charging path and the discharging path to reduce the interface path of the backup power storage module ...
