As shown in fig. 4, an embodiment of the present invention provides a power supply method based on the power supply apparatus provided in the foregoing embodiment, where the method may include the following steps:
step 401: the power supply module converts an electric signal provided by a peripheral power supply module into a required voltage signal, and supplies power to at least one peripheral electric component through the voltage signal.

An embodiment of the present invention provides a server, including: at least one power consuming component, and the power supply of any of the above embodiments.
It should be noted that the existing server generally adopts an N + N redundancy form to supply power, that is, there are two power modules, and when one of the power modules fails, the other power module supplies power, but with the development of electronic technology, the probability of failure of the power module is greatly reduced, so in the embodiment of the present invention, only one power module may be used to supply power, and the existing other power module is replaced by a standby power module, so that the space of the server can be saved.
Specifically, as shown in fig. 5, the present invention is a server, including: the power supply system comprises a power supply module 501, a standby power module 502, a power utilization component a (503) and a power utilization component b (503), wherein the standby power module 502 comprises a standby battery pack 5021, a battery management unit 5022 and a charging unit 5023. The power supply module 501 and the standby power module 502 are both connected to a peripheral power supply module (e.g., a 220V ac power supply module).
A power supply method based on the power supply device in any one of the above embodiments according to an embodiment of the present invention is described in detail below.
For example, in the process of server assembly, while assembling required electric components, a power supply module (e.g., a PSU module) and a backup power module (e.g., a lithium battery pack, a charging unit, a battery management unit, etc.) are deployed in the servers, so that when a data center deploys the servers, it is not necessary to deploy a large number of UPSs in advance, because each server is installed with a backup power module, so that when an external power supply module, such as a mains ac 220V, is normal, the PSU module supplies power to the electric components in the servers, and when a mains power outage occurs, the PSU module cannot provide power supply voltage for the electric components, and at this time, the fully charged lithium battery pack in the backup power module can be used for discharging, so as to continue to supply power to the electric components, so that each server is deployed in the data center, each server can utilize an internally arranged battery pack as a backup power source.
In summary, the embodiments of the present invention have at least the following advantages:
1. in the embodiment of the invention, the power supply device may include a power supply module and a backup power module, the two modules are arranged in each server and are respectively connected with the peripheral power supply module, so that when the power supply module is not abnormal, the power supply module converts an electrical signal provided by the power supply module into a required voltage signal to supply power to at least one power consumption component in the server, and at the same time, a battery management unit in the backup power module also controls a backup battery pack to be charged through the power supply module, when the power supply module is abnormal, the power supply module will not output the voltage signal, so that when the battery management unit does not detect that the power supply module outputs the voltage signal, the backup battery pack is controlled to discharge to output the required voltage signal, thereby continuing to power the at least one powered component. Because a centralized UPS standby power supply mode is not adopted any more, the power supply devices are distributed in each server, the waste of resources can be reduced, and the utilization rate of the resources can be improved.
2. In the embodiment of the invention, the lithium battery pack is adopted, and because the lithium battery pack has small volume and high energy density, the backup requirement can be met by arranging a small number of lithium battery packs, so that the space of the server is saved.
3. In the embodiment of the invention, a centralized UPS power supply mode is not used, so that two independent spaces for respectively storing the UPS and the lead-acid storage battery are not required, and a large amount of space is saved.
