Obviously, the described embodiments It is a part of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the protection of the present invention. scope.

As shown in Figure 1, an embodiment of the present invention provides a power supply device, which may include:

The voltage conversion group 101 includes at least two voltage suppliers, each voltage supplier is used to receive a first voltage input from the outside, and convert the first voltage into a power supply voltage, and use the power supply voltage to provide Power supply for each server and cooling system;

The management unit 102 is configured to set the first threshold and the second threshold, detect the power supply voltage of the voltage conversion group 101 and the number of voltage suppliers in the voltage conversion group 101, and when it is detected that the power supply voltage is less than When the first threshold is reached, send a first switching command to the standby power supply unit 103; when it is detected that the number of voltage suppliers powered in the voltage conversion group 101 reaches the second threshold, send a second switching command Give instructions to the standby power supply unit 103;

The standby power supply unit 103 is configured to supply power to each server and cooling system of the peripheral device when receiving the first switching instruction sent by the management unit 102; when receiving the second switching instruction sent by the management unit 102 When commanded, stop power supply.

According to the above-mentioned embodiment, each voltage supplier in the voltage conversion group receives the first voltage input from the outside, and the management unit detects the power supply voltage of the voltage conversion group and the voltage supplied by the voltage conversion group in real time. The number of voltage suppliers. When it is detected that the power supply voltage is less than the set first threshold, a first switching instruction is sent to the backup power supply unit. system power supply, when it is detected that the number of voltage suppliers powered by the voltage conversion group reaches the set second threshold, a second switching instruction is sent to the standby power supply unit, and the standby power supply unit stops supplying power. The invention is to detect the power supply voltage of the voltage conversion group and the number of voltage suppliers in the voltage conversion group in real time to complete the power supply and redundant power supply for each server and heat dissipation system of the peripheral equipment. The transformation project of power supply avoids the situation that a certain voltage supplier inside the PSU of the voltage conversion group or less than the number required for normal power supply is started first, so it can ensure the continuous and stable operation of the server and cooling system in the cabinet.

In another embodiment of the present invention, as shown in FIG. 2, the backup power supply unit 103 includes: a control subunit 201 and a power supply battery pack 202, wherein,

The control subunit 201 is configured to control the power supply battery pack 202 to output a second voltage when receiving the first switching instruction sent by the management unit 102; when receiving the second switching instruction sent by the management unit 102 , controlling the group of power supply batteries 202 to output a third voltage, wherein the second voltage is greater than the power supply voltage, and the third voltage is less than the power supply voltage;

The backup power supply unit receives the first switching instruction sent by the management unit, and the control subunit controls the power supply battery pack to output a second voltage according to the first switching instruction, and the second voltage is greater than the power supply voltage, the standby power supply unit receives the second switching instruction sent by the management unit, at this time, the number of voltage suppliers in the voltage conversion group reaches the second threshold, and the control subunit according to the second switching The instruction controls the power supply battery pack to output a third voltage, and the third voltage is lower than the power supply voltage, so as to avoid the free switching of the power supply of the voltage conversion group and the power supply battery pack.

The power supply battery pack 202 is used to supply power to each server and heat dissipation system of the peripheral equipment when outputting the second voltage.

For example, the power supply voltage provided by the voltage conversion group is 12.6V. When the power supply voltage provided by the voltage conversion group decreases, the control subunit receives the first switching command from the management unit, which will control the power supply battery pack to output the second The voltage is 12.7V, which supplies power to each server and heat dissipation system of the peripheral equipment. The second voltage 12.7V here is greater than the power supply voltage 12.6V, which can ensure that the number of voltage suppliers recovering power supply in the voltage conversion group is less than When the second threshold is reached, the voltage suppliers in the voltage conversion group are in an unloaded state, which avoids unstable operation of the server due to insufficient number of voltage suppliers. When the number of voltage suppliers reaches the second threshold, the control subunit receives the second switching instruction from the management unit, which will control the power supply battery pack to output a third voltage of 12.5V. At this time, the third voltage is lower than the power supply voltage, the power supply battery pack stops supplying power to each server and heat dissipation system of the peripheral device, so that the voltage suppliers in the voltage conversion group that reach the required number of normal power supply are in a loaded state, replacing the power supply battery pack Power is supplied to each server and cooling system of the peripheral equipment. As another example, the power supply battery pack may use distributed lithium batteries, which can provide efficient and stable power supply. In the above process, before the power supply of the power supply is abnormal and the redundant power supply is started, the second voltage output by the power supply battery pack can fully satisfy the normal operation of the peripheral server and the heat dissipation system. The group output voltage is converted to a third voltage lower than the power supply voltage, so as to switch to the redundant power supply, so that the conversion process of the power supply and the redundant power supply to each server and heat dissipation system of the peripheral device can achieve seamless switching.

In another embodiment of the present invention, as shown in FIG. 3 , it further includes: a power supply copper bar 301,

The power supply copper bar 301 is respectively connected with the voltage conversion group 101 and the power supply battery group 202, and is used to obtain the power supply voltage converted by the voltage conversion group 101 when the power supply of the voltage conversion group 101 is normal, and through the power supply The voltage supplies power to each server and heat dissipation system of the peripheral equipment. When the power supply of the voltage conversion group 101 is abnormal, the second voltage output by the power supply battery pack 202 is obtained, and each server and heat dissipation system of the peripheral equipment is supplied by the second voltage. The system is powered.

For example, when the power supply of the voltage conversion group is normal, the voltage conversion group will convert the power supply voltage of the peripheral device into a power supply voltage to supply power for each server and cooling system of the peripheral device. For example, the power supply voltage of the peripheral device is AC+ 220V voltage, then when +220V voltage is input to the voltage conversion group, the voltage conversion group will convert the input +220V voltage to 12.6V voltage, and use 12.6V voltage to supply power to the power supply copper bar, and the peripheral Each server and heat dissipation system is connected to the power supply copper bar, and the power supply copper bar uses 12.6V voltage to supply power to each peripheral server and heat dissipation system, and when the power supply of the voltage conversion group is abnormal, the power supply battery pack takes over The power supply of the peripheral equipment supplies power for the voltage conversion group, such as the power supply battery pack provides 12.7V voltage, and transmits the 12.7V voltage to the power supply copper bar, and the servers and cooling systems of the peripheral equipment are connected with the described The power supply copper bar is connected, and the power supply copper bar uses 12.7V voltage to supply power to each peripheral server and cooling system.

According to the above embodiment, the power supply copper bars are respectively connected to the voltage conversion group and the power supply battery pack, and the voltage conversion group and the power supply battery pack are connected to the external server and the power supply copper bar respectively. The heat dissipation system supplies power, so when the power supply of the voltage conversion group is abnormal, the power supply battery pack will provide the second voltage for the power supply copper bar, so as to ensure the normal power supply of each peripheral server and cooling system connected to the power supply copper bar .

In addition, the positional relationship among the voltage conversion group 101 , the backup power supply unit 103 , and the server and the positional relationship in the cabinet are shown in FIG. 4 . Wherein, the backup power supply unit is placed in the Rack cabinet, so for the convenience of placement in the Rack cabinet, the size of the backup power supply unit will be the same as the size of each server and cooling system in the Rack cabinet Similarly, except for the position where the voltage conversion group is placed in the Rack cabinet, the backup power supply unit can be placed in any position. After the position of the backup power supply unit in the Rack cabinet is determined, you can use The crown clip supporting hot plugging is connected to the power supply copper bar, so as to facilitate online replacement of the standby power supply unit. In addition, according to the actual working maximum power of the server and cooling system in the Rack cabinet, the electric capacity of the power supply battery pack is selected to ensure that the power supply battery pack can fully load the 8.8KW system of the Rack cabinet , Backup time can reach 15 minutes.

In another embodiment of the present invention, as shown in FIG. 5, the standby power supply unit 103 further includes: a charging subunit 501, wherein,

The control subunit 201 is used to set the power threshold, when the power supply battery pack 202 outputs a third voltage, monitor in real time whether the remaining power of the power supply battery pack 202 is lower than the power threshold, and if so, trigger the charging electronic unit 501;

When the remaining power of the power supply battery pack 202 is higher than the power threshold, the charging subunit 501 will not be triggered, and the power supply battery pack 202 is in a floating charging state; the remaining power of the power supply battery pack 202 is lower than When the power threshold is reached, the charging subunit 501 will be triggered, and the power supply battery pack 202 will be charged.

The charging subunit 501 is connected to the power supply copper bar 401 and the power supply battery pack 202 respectively, and is used to use the power supply voltage on the power supply copper bar to charge the power supply battery when receiving the trigger of the control subunit 201 Charge the power supply battery pack.

For example, the power threshold set by the control subunit is the percentage of remaining power, such as 95%. When the power supply battery pack outputs a third voltage of 12.6V, the control subunit monitors in real time whether the power remaining power of the power supply battery pack is lower than The power threshold is set, for example, if it is detected that the remaining power is less than 95%, then the charging subunit will be triggered to charge the power supply battery pack, and the charging subunit and the power supply copper bar and all The power supply battery pack is connected, and when the charging subunit is triggered, the power supply voltage on the power supply copper bar is used to charge the power supply battery pack. In the early stage of the charging process, the constant current fast charging method is adopted, and when the power reaches 95%, the constant voltage floating charging method is used, which not only ensures the charging of the power supply battery pack, but also improves the life of the power supply battery pack.

According to the above embodiment, the power supply battery pack includes a charging subunit. When the voltage conversion group works normally, the charging subunit will monitor the power supply battery in real time according to the power threshold set by the control subunit. When it is detected that the remaining power is lower than the threshold of the remaining power, it will use the power supply copper bar to charge the charging sub-unit with the power supply voltage to ensure that the power supply battery pack is fully charged at any time. When the power supply of the voltage conversion group is abnormal, the power supply battery pack has sufficient power to supply power to the peripheral server and cooling system, and ensure the continuous and stable operation of the server and cooling system in the cabinet.

In another embodiment of the present invention, each voltage supplier in the voltage conversion group is connected to two power supplies, and these two power supplies are respectively a power supply and a redundant power supply. Once the power supply of the power supply is abnormal, the redundant power supply The power supply will start to replace the power supply to supply power to the voltage conversion group.

Each of the voltage suppliers is respectively connected to the power supply of the peripheral device and the redundant power supply of the peripheral device, and is further used to receive the first voltage input by the power supply of the peripheral device, when the power supply of the peripheral device is abnormal , stop outputting the power supply voltage, and receive a fourth voltage input by the redundant power supply of the peripheral, and convert the fourth voltage into the power supply voltage.

For example, the power supply of the peripheral equipment is an AC +220V power supply, and the redundant power supply is a diesel generator. The conversion group provides the first voltage 220V, but when the +220V power supply is abnormal, it stops outputting the 220V power supply voltage. At this time, the redundant power supply starts to work, such as a diesel generator, and starts to output the fourth voltage 220V. Power is supplied to the voltage conversion group.

According to the above-mentioned embodiment, two power supplies are provided externally, namely the power supply and the redundant power supply. These two power supplies are respectively connected to each voltage supplier in the voltage conversion group. When the power supply voltage is output, the redundant power supply will immediately take over the power supply and output the fourth voltage for each voltage supplier in the voltage conversion group. The entire power supply process is uninterrupted, ensuring the continuous stability of the server and cooling system in the cabinet running.

The information exchange and execution process among the units in the above-mentioned device are based on the same concept as the method embodiment of the present invention, and the specific content can refer to the description in the method embodiment of the present invention, and will not be repeated here.

A power supply system provided by an embodiment of the present invention, referring to FIG. 6 , includes: a power supply device 601, a power supply 602, and a redundant power supply 603, wherein,

The power supply 602 and the redundant power supply 603 are respectively connected to the voltage conversion group in the power supply device 601;

The power supply 602 is configured to output the first voltage to the voltage conversion group in the power supply device;

The redundant power supply 603 is configured to output a fourth voltage to the voltage conversion group in the power supply device when the power supply of the power supply is abnormal.

For example, the power supply is a +220V power supply, and the redundant power supply is a diesel generator. They are respectively connected to the voltage conversion group in the power supply device. When the power supply is normal, they output 220V to the voltage conversion group in the power supply device. voltage, when the power supply works abnormally and cannot output the normal power supply voltage, the redundant power supply diesel generator will work immediately, and output the fourth voltage 220V to the power supply voltage to the voltage conversion group in the voltage device to ensure The server in the cabinet and the heat dissipation system operate continuously and stably.

A power supply method provided by an embodiment of the present invention is applied to a cabinet, see Figure 7, including:

Step 705: When it is detected that the power supply voltage is lower than the first threshold, control the standby power supply unit to supply power to each server and cooling system of the peripheral device;

Step 706: When it is detected that the number of voltage suppliers supplying power in the voltage conversion group reaches the second threshold, control the standby power supply unit to stop supplying power.

In another embodiment of the present invention, when the power supply of the peripheral device is restored from power failure to the redundant power supply or the power supply of the peripheral device, each voltage supplier in the voltage conversion group establishes a normal power supply voltage There is a certain time difference in the input, and at this time, it is necessary to output the output voltage of the power supply battery pack in the backup power supply unit to a specific voltage value. The specific implementation of step 705 includes: controlling the power supply battery pack in the backup power supply unit to output a second voltage, wherein the second voltage is greater than the power supply voltage; the specific implementation of step 706 includes: controlling the The power supply battery pack in the standby power supply unit outputs a third voltage, wherein the third voltage is lower than the power supply voltage.

In another embodiment of the present invention, since the voltage conversion group and the standby power supply unit are used to supply power to each server and heat dissipation system of the peripheral device, in order to ensure the The power supply of the heat dissipation system is uniform, and the number of lines is reduced. Therefore, the above method further includes: setting a power supply copper bar; the specific implementation of step 703 includes: when the power supply of the voltage conversion group is normal, obtain The power supply voltage supplies power to each server and heat dissipation system of the peripheral device; the specific implementation of step 705 includes: when the power supply of the voltage conversion group is abnormal, obtaining the second output of the power supply battery pack in the backup power supply unit voltage, and supply power to each server and cooling system of the peripheral device through the second voltage.

In another embodiment of the present invention, when the power supply of the peripheral device is abnormal and cannot normally provide a power supply voltage, the redundant power supply of the peripheral device will immediately take over the power supply of the peripheral device for power supply. In addition, when the power supply of the peripheral device is abnormal, the power supply battery pack will supply power to the power supply copper bar. When the redundant power supply of the peripheral device takes over or the power supply of the peripheral device is normal again, the power supply battery The battery pack will stop supplying power. Since the power supply battery pack supplies power to each server and cooling system through the power supply copper bar, the power of the power supply battery pack is reduced. When the power of the power supply battery pack is reduced to a certain value, it may affect the power supply battery pack next time. impact, then, in order to ensure the continuous use of the power supply battery pack, in this embodiment, the power supply battery pack is supplemented. The above method further includes: setting the power threshold; when the power supply battery pack outputs a third voltage , monitor in real time whether the remaining power of the power supply battery pack is lower than the power threshold, and if so, use the power supply voltage on the power supply copper bar to charge the power supply battery pack.

In one embodiment of the present invention, since the power supply time of the above-mentioned power supply battery pack cannot continue to supply power, in order to further ensure the continuity of power supply of the server and the cooling system, the specific implementation of step 702 includes: receiving the first Voltage; after the control standby power supply unit supplies power to each server and heat dissipation system of the peripheral equipment, before the control standby power supply unit stops supplying power, it further includes: receiving the power of the peripheral equipment through the at least two voltage suppliers A fourth voltage input by the redundant power supply, converting the fourth voltage into the power supply voltage.

In order to make the purpose, technical solution and advantages of the present invention more clear, below in conjunction with the power supply system shown in Figure 9, through the power supply in the power supply system, the redundant power supply, the power supply device and the voltage conversion group in the power supply device, the backup power supply unit The interaction process between the management unit and the management unit is described. The power supply system is applied to the power supply method in the cabinet. As shown in FIG. 8, the power supply method may include the following steps:

Step 801: setting the power supply copper bar;

As shown in Figure 9, the power supply copper bar 904 is connected to each voltage supplier 9011 in the power supply battery pack 9032, the charging subunit 9033 and the voltage conversion group 901 respectively,

When the power supply of the voltage conversion group 901 is normal, the power supply voltage is obtained through the power supply copper bar 904, and supplies power to each server and cooling system of the peripheral equipment;

When the power supply of the voltage conversion group 901 is abnormal, the second voltage output by the power supply battery pack 9032 in the backup power supply unit 903 is obtained, and the peripheral servers and cooling systems are powered by the second voltage.

For example, when the power supply of the voltage conversion group is normal, for example, the power supply voltage is 12.6V, this power supply voltage is directly transmitted to the power supply copper bar, and supplies power to each peripheral server and heat dissipation system through the power supply copper bar. When the power supply of the voltage conversion group is abnormal, the power supply battery pack in the backup power supply unit outputs a second voltage of 12.7V, and this second voltage of 12.7V is directly transmitted to the power supply copper bar, through which each server of the peripheral equipment and cooling system power supply.

Step 802: Setting the first threshold, the second threshold, and the power threshold;

The first threshold is the power supply voltage threshold, the second threshold is the number threshold of the voltage suppliers 9011 in the voltage conversion group 901, and the power threshold is the remaining power threshold of the power supply battery pack 9032;

For example, the applied cabinet is a Rack cabinet. The voltage conversion group of this cabinet can adopt 4+4 redundancy or 4+2 redundancy system. In this example, the voltage conversion group of this cabinet can adopt 4+4 redundancy, and the Rack The normal output voltage of the voltage conversion group in the cabinet is 12.6V, so the first threshold can be set to be 12.35V. In addition, since the 4+4 redundancy mode is adopted in this example, the second threshold may be 4. The power threshold is the remaining power threshold of the power supply battery pack, which can be set according to specific business needs, such as 80% or 95%.

Step 803: receiving a first voltage input from the outside through at least two voltage suppliers;

As shown in FIG. 9 , at least two voltage suppliers 9011 in the voltage conversion group 901 receive the first voltage input from the power supply 905 . For example, if the power supply 905 is a +220V AC power supply, then the first voltage received by the at least two voltage suppliers 9011 from the outside is 220V voltage.

Step 804: converting the first voltage into a power supply voltage through at least two voltage suppliers 9011;

At least two voltage suppliers 9011 in the voltage conversion group 901 convert the received first voltage into the power supply voltage required by each peripheral server and cooling system.

For example, the at least two voltage suppliers convert the received first voltage 220V into the power supply voltage 12.6V required by each server and heat dissipation system of peripheral devices.

Step 805: Use the management unit to detect whether the power supply voltage is lower than the first threshold, if yes, execute step 806; otherwise, execute step 809;

For example, the set first threshold value is 12.35V, and if the management unit detects that the power supply voltage is 12.4V, 12.5V, 12.35V, 12.55V, which are values greater than or equal to the first threshold value 12.35V, then perform step 809; If the management unit detects that the detected power supply voltage is 12.1V, 12.2V, 12.34V, etc., which is smaller than the first threshold 12.35V, then step 806 is executed.

Step 806: Control the power supply battery pack in the backup power supply unit to output a second voltage, wherein the second voltage is greater than the power supply voltage;

As shown in FIG. 9, the control subunit 9031 in the backup power supply unit 903 controls the power supply battery pack 9032 to output a second voltage of 12.7V. This second voltage 12.7V is greater than the power supply voltage of 12.6V, because the abnormal power supply from During the transition process of the redundant power supply of peripheral equipment or the normal power supply of peripheral equipment, each voltage supplier 9011 in the voltage conversion group 901 establishes a normal power supply voltage of 12.6V input, and there is a certain time difference. Power protection may occur in the server and heat dissipation system, so the output voltage of the power supply battery 9032 in the backup power supply unit 903 is raised to 12.7V, so that even if each voltage supplier 9011 in the voltage conversion group 901 establishes a normal power supply There is a certain time difference in the input of the voltage 12.6V, and each voltage supplier 9011 will not be loaded, which will not cause the server and cooling system to be interrupted. In addition, since the backup power supply unit 903 is applied in a cabinet, such as a Rack cabinet, since the load of the Rack cabinet system can reach 8.8KW, then the voltage conversion group 901 is switched to the backup power supply unit 903 When the power supply battery pack 9032 outputs the second voltage of 12.7V, it will generate a voltage DROP, the lowest point of the DROP voltage, as shown in Figure 10 V1, the tested voltage is greater than 11.8V, which can fully meet the needs of peripheral servers and heat dissipation systems of normal work.

Step 807: Transmitting the second voltage to the power supply copper bar;

When the power supply battery pack 9032 outputs the second voltage, it will transmit the second voltage to the power supply copper bar 904, for example, when the power supply battery pack 9032 outputs the second voltage of 12.7V. The voltage of 12.7V will be transmitted to the power supply copper bar 904 .

Step 808: supply power to each server and heat dissipation system with the second voltage through the power supply copper bar, and execute step 811;

For example, the power supply copper bar 904 receives the second voltage of 12.7V, and uses the 12.7V voltage to supply power to each server and cooling system, and while the power supply copper bar 904 is powered by the second voltage of 12.7V, step 811 is executed.

Step 809: Transmitting the power supply voltage to the power supply copper bar;

For example, the set first threshold value is 12.35V, if the management unit 902 detects that the power supply voltage is 12.6V, then the power supply voltage 12.6V is greater than the first threshold value 12.35V, then the power supply voltage of 12.6V is transmitted Provide the power supply copper bar 904.

Step 810: use the power supply voltage to supply power to each server and heat dissipation system of the peripheral equipment through the power supply copper bar, and end the current process;

For example, when the power supply copper bar 904 receives a power supply voltage of 12.6V, then the power supply copper bar 904 uses the obtained voltage to supply power to various servers and heat dissipation systems of peripheral devices.

Step 811: Start the redundant power supply, and receive the fourth voltage input by the redundant power supply through the at least two voltage suppliers;

For example, when the power supply copper bar 904 uses the obtained second voltage 12.7V to supply power to each server and heat dissipation system, start the redundant power supply 906, such as a diesel generator, and at least two voltage supplies in the voltage conversion group 901 9011 to receive the fourth voltage 220V provided by the diesel generator.

Step 812: converting the fourth voltage into a supply voltage by the at least two voltage suppliers;

For example, if at least two voltage suppliers 9011 in the voltage conversion group 901 receive the fourth voltage 220V provided by the diesel generator, then at least two voltage suppliers 9011 convert the fourth voltage 220V into a power supply voltage of 12.6 V.

Step 813: Use the management unit to detect whether the number of the voltage suppliers supplying power reaches the second threshold, if yes, execute step 814; otherwise, execute step 807;

For example, if the voltage conversion group 901 of the cabinet adopts 4+4 redundancy, then the set second threshold value is 4, and then the management unit 902 will detect the number of normal power supplies in the voltage suppliers 9011 for power supply in real time, such as detecting If the number of the voltage suppliers 9011 supplying power normally is 3, then step 807 is performed. For example, if it is detected that the number of voltage suppliers 9011 supplying power normally is 4, then step 814 is performed.

Step 814: Control the backup power supply unit to output the third voltage, and stop power supply;

For example, the management unit 902 will detect in real time that the number of normal power supplies in the voltage supplier 9011 for power supply has reached the set second threshold, then the control subunit 9031 in the backup power supply unit 901 controls the charging subunit 9032 The third voltage of 12.6V is output, and the power supply to the power supply copper bar 904 is stopped. In addition, since the backup power supply unit 903 is applied in a cabinet, such as a Rack cabinet, since the load of the Rack cabinet system can reach 8.8KW, then the power supply battery in the backup power supply unit 903 is switched to the voltage conversion When the output power supply voltage of group 901 is 12.6V, a voltage DROP will be generated. The lowest point of this DROP voltage is V2 shown in Figure 11. After testing, the voltage is greater than 12V, which can fully meet the normal operation of peripheral servers and cooling systems.

Step 815: supply power to each server and heat dissipation system with the power supply voltage converted from the fourth voltage through the power supply copper bar;

For example, the power supply voltage 12.6V converted from the fourth voltage 220V through the power supply copper row 904 supplies power to each server and cooling system.

Step 816: Monitor in real time whether the remaining power of the power supply battery pack is lower than the power threshold, if yes, execute step 817, otherwise, execute step 818;

After the power supply battery pack 9032 stops supplying power, it is necessary to monitor in real time whether the remaining power of the power supply battery pack 9032 is lower than the power threshold, such as the set power threshold is 95%, when the monitored power supply battery pack 9032 remaining If the power is 80%, then step 817 is executed, and when the monitored remaining power of the power supply battery pack 9032 is 97%, then step 818 is executed.

Step 817: Use the power supply voltage on the power supply copper bar to charge the power supply battery pack, and end the current process;

For example, the power supply voltage on the power supply copper bar 904 is 12.6V. When the power supply battery pack 9032 needs to be charged, the power supply voltage of 12.6V is used to charge the power supply battery pack 9032. The charging process can adopt constant current Fast charging method.

Step 818: Control the power supply battery pack to be in the floating charging state.

For example, when the remaining power of the power supply battery pack 9032 is higher than the power threshold, for example, the set power threshold is 95%, and the monitored remaining power of the power supply battery pack 9032 is 97%, then the power supply The battery pack 9032 carries out constant-voltage float charging, thereby improving the service life of the battery pack 9032 for power supply.

The present invention adopts Real-time detection of the power supply voltage of the voltage conversion group and the number of voltage suppliers in the voltage conversion group to complete the transformation of the power supply and redundant power supply to the various servers and cooling systems of the peripheral devices The project avoids the situation that a certain voltage supplier inside the PSU of the voltage conversion group or a number less than the normal power supply requirement is started first, so it can ensure the continuous and stable operation of the server and cooling system in the cabinet.

2. Receive the switching instruction through the control subunit in the backup power supply unit, and adjust the power supply battery pack in the backup power supply unit to output the second voltage or the third voltage through the switching instruction, wherein the second voltage is greater than the supply voltage, and the third voltage is less than Power supply voltage, that is, when the power supply battery pack outputs the second voltage, the power supply battery pack supplies power to the servers and cooling systems of each peripheral device; when the power supply battery pack outputs the third voltage, the voltage conversion group supplies power to the servers and cooling systems of each peripheral device For power supply, the seamless switching between the voltage conversion group and the power supply battery group can be realized only by adjusting the voltage of the power supply battery group, thereby further ensuring the stability of the server and cooling system operation.

3.

Unified power supply management.

4. The power supply battery pack includes a charging subunit. When the voltage conversion group works normally, the charging subunit will monitor the remaining power of the power supply battery pack in real time according to the power threshold set by the control subunit. Power condition, when it is detected that the remaining power is lower than the threshold of the remaining power, the charging sub-unit will be charged by the power supply voltage through the power supply copper bar, so as to ensure that the power supply battery pack is fully charged at any time, and ensure that once the voltage When the power supply of the conversion group is abnormal, the power supply battery pack has sufficient power to charge the peripheral server and cooling system, and ensure the continuous and stable operation of the server and cooling system in the cabinet.

5. There are two peripheral power supplies, namely the peripheral power supply and the peripheral redundant power supply. These two peripheral power supplies are respectively connected to each voltage supplier in the voltage conversion group. Once the peripheral When the power supply of the power supply works abnormally and cannot output the power supply voltage normally, the redundant power supply will immediately take over the power supply of the peripheral equipment and output the fourth voltage for each voltage supplier in the voltage conversion group, so that the power supply battery pack can only As a transitional power supply, the entire power supply process is not interrupted to ensure continuous and stable operation of the server and cooling system in the cabinet.
