Specific embodiment
Below in conjunction with attached drawing, the technical solution in the application is described.
Fig. 1 shows the schematic flow chart of the method for the application one embodiment, as shown in Figure 1, providing this kind of Shen
A kind of server method of supplying power to please be provided, comprising:
Step 110, when alternating current normal power supply, power module (Power Supply Unit, PSU) passes through power supply busbar
It is powered for server, reserve battery (Backup Battery Unit, BBU) is in charged state；When alternating current power down, institute
It states power supply busbar supply voltage and is down to threshold voltage hereinafter, the BBU starts to be powered for the server.
Optionally, as the application one embodiment, the method also includes: when the PSU restores to the server
When power supply, the BBU stops being that the server is powered.
Optionally, as the application one embodiment, the BBU includes battery management system (Battery
Management System, BMS), lithium battery, charging circuit and discharge circuit.
Optionally, as the application one embodiment, the method also includes: when the PSU is normally the server
Power supply and when the BBU remaining capacity is higher than 50%, BMS control BBU carries out charge and discharge self-test process.
Optionally, as the application one embodiment, the threshold voltage is 12.1V.
The embodiment of the design method provides a kind of suitable for server power supply design method.It include clothes in the present embodiment
Be engaged in device, power supply, BBU etc..
Wherein the main power supply of server is provided by a power supply, and it is defeated that 220V alternating current is transformed to 12.3V DC voltage by power supply
Server master board is arrived out, the primary input as server.BBU is made of lithium battery group, BMS, charging circuit and discharge circuit,
BBU is that lithium battery group charges by inversion boosting, discharge circuit is by lithium battery using the output 12.3V of redundant power as input
Voltage step-down is to 12.1V, as backup power source.BMS manages charge and discharge, that is, self-checking function of BBU, and is shown by BBU indicator light
Current state.
When alternating current power-off, electric energy needed for providing server as BBU saves significant data and searching to provide for client
The time of power available.
Fig. 2 shows the schematic block diagrams that Fig. 2 is the device of the application one embodiment.
As shown in Fig. 2, server takes electricity from power supply busbar, BBU and PSU are output to power supply busbar jointly, wherein PSU conduct
Main output, BBU output are used as standby.When PSU is worked normally, BBU is in charged state, stops after fully charged.Work as alternating current
Power down, PSU output are closed, and power supply busbar voltage is when being down to 12.1V, BBU adapter tube server load, are provided 15 minutes or more
Prolonged electric energy supply.Data needed for client is saved using this time, or power available is found, to avoid not
Necessary loss.
BBU unit includes BMS, lithium battery, charging circuit and discharge circuit.BMS is each by signal line traffic control and monitoring
Partial working condition.In the case where condition meets, BMS controls BBU and carries out self-test, and BMS passes through self-test sign on for BBU
Output adjustment is higher than PSU output voltage, to start to discharge, into self-test process, when BMS monitors BBU residue to 12.4V
Electricity is down to 50%, issues and stops self-checking command.
Server B MC is connect by signal wire with BBU and PSU, and can read the information of BBU and PSU.
According to present invention design, it can be achieved that being designed in server system stable power-supplying, particularly with the lesser client of dosage
For, it can greatly increase the stability of data.Original 1+1 Redundancy Design is changed to the design of PSU+BBU simultaneously, for
Server internal space hold does not increase, while reducing by a PSU and increasing a BBU, has almost no change in terms of cost.
