Description

Technical Field

[0001] The present application relates to the field of power supply technology, and in particular to a power supply management circuit, a power supply control method, a power supply management device, and a server cabinet. Background Art

[0002] A digital center is a server cluster equipped with capabilities such as artificial intelligence computing and big data processing. It typically requires continuous operation, necessitating a reliable power supply. To ensure this, additional batteries are typically installed within the center to power it when a larger, more stable power source is available. Charging stations, on the other hand, are terminals capable of charging devices such as electric vehicles and electric bicycles. Additional batteries can also be provided to improve charging efficiency.

[0003] However, the relevant circuits of the digital center and the relevant circuits of the charging piles are independent of each other, and the resource correlation is low, resulting in low resource utilization efficiency. Summary of the Invention

[0004] The present invention provides a power supply management circuit, a power supply control method, a power supply management device, and a server cabinet. The present invention can improve the efficiency of power resource utilization.

[0005] According to a first aspect of the present application, a power supply management circuit is provided, comprising:

[0006] The controller and the first AC-DC conversion circuit, the switch circuit, and the first DC conversion circuit connected in sequence; the first DC conversion circuit is used to connect to the first battery pack, and the first AC-DC conversion circuit is used to connect to the AC mains;

[0007] The switch circuit is used to connect the second battery pack and the charging terminal, the second battery pack is used to connect to the second AC-DC conversion circuit, and the second AC-DC conversion circuit is used to connect the server and the AC mains to power the server;

[0008] The first battery pack, the second battery pack, the first AC-DC conversion circuit, the second AC-DC conversion circuit, the charging terminal, the switch circuit, and the first DC conversion circuit are respectively communicatively connected to the controller;

[0009] The controller is used to operate and control the switch circuit, the first AC-DC conversion circuit, and the first DC conversion circuit to adjust the working state of the first battery pack and / or the second battery pack.

[0010] In the embodiment of the present application, the first battery pack, the second battery pack, and the charging terminal are connected via a power management circuit, establishing a relationship between the controller and the other circuits. This allows the controller to control the operation of the switching circuit, the first AC-DC conversion circuit, and the first DC conversion circuit to adjust the operating state of the first and / or second battery packs. By using the first and second battery packs together, the power resources of the first and second battery packs are effectively increased, avoiding waste and idleness of power resources and effectively improving resource utilization efficiency.

[0011] In conjunction with the first aspect, in certain implementations of the first aspect, when the controller determines that the server is not operating at a peak load and the charging terminal is not connected to a device to be charged, the controller is specifically configured to execute:

[0012] The first AC-DC conversion circuit is controlled to charge the second battery pack and / or the first DC conversion circuit is controlled to switch to a charging mode to charge the first battery pack.

[0013] When the controller determines that the server is not operating at a peak load and the charging terminal is connected to a device to be charged, the controller is configured to perform at least one of the following:

[0014] controlling the first AC-DC conversion circuit to supply power to the charging terminal;

[0015] Alternatively, if the device to be charged requires fast charging, the first DC conversion circuit is controlled to switch to a power supply mode so that the first battery pack supplies power to the charging terminal, and / or the second battery pack is controlled to supply power to the charging terminal, and / or when the remaining power of the first battery pack is less than a first threshold value, the first battery pack is controlled to stop supplying power to the charging terminal;

[0016] Alternatively, if the charging of the device to be charged is completed, the first DC conversion circuit is controlled to switch to a charging mode to charge the first battery pack.

[0017] In this embodiment, when the server is not operating at peak load, the controller limits the operations it performs in different scenarios, taking into account whether the charging terminal is connected to a device to be charged. This allows the first and second battery packs to complete charging in a timely manner, and after the charging terminal is connected to the device to be charged, it charges the device in different charging modes based on the device's needs. This balances the needs of high resource utilization and fast charging, effectively improving the operational and management efficiency of the entire system.

[0018] In conjunction with the first aspect, in certain implementations of the first aspect, when the controller determines that the server is operating at a peak load and the charging terminal is not connected to a device to be charged, the controller is specifically configured to perform at least one of the following:

[0019] Controlling the second battery pack to supply power to the server and controlling the first AC / DC conversion circuit to charge the second battery pack;

[0020] Alternatively, if it is determined that the remaining power of the second battery pack is greater than the second threshold value, the first DC conversion circuit is controlled to stop working so that the first battery pack does not supply power to the server;

[0021] Alternatively, if it is determined that the remaining power of the second battery pack is less than or equal to the second threshold value, controlling the first DC conversion circuit to switch to the power supply mode so that the first battery pack supplies power to the server;

[0022] Alternatively, controlling the first DC conversion circuit to switch to a power supply mode so that the first battery pack supplies power to the server;

[0023] When the controller determines that the server is operating at a peak load and the charging terminal is connected to a device to be charged, the controller is specifically configured to perform at least one of the following:

[0024] Control the second battery pack to power the server;

[0025] Alternatively, if the remaining power of the second battery pack is greater than a third threshold value, the first DC conversion circuit is controlled to stop working, so that the first battery pack does not work;

[0026] Alternatively, if the remaining power of the second battery pack is less than or equal to the first threshold value, controlling the first DC conversion circuit to switch to the power supply mode so that the first battery pack supplies power to the server;

[0027] Alternatively, the first AC-DC conversion circuit is controlled to supply power to the charging device.

[0028] In this embodiment, when the server is operating at peak load, the controller's corresponding operations are limited based on different scenarios, depending on whether the charging terminal is connected to the device to be charged. This prioritizes ensuring the server's power needs, while also improving the charging efficiency of the device to be charged. This allows for efficient management of the operating status of the first and second battery packs, further improving the operational and management efficiency of the entire system.

[0029] In conjunction with the first aspect, in certain implementations of the first aspect, if the AC mains power supply is abnormal, the controller is further configured to perform at least one of the following:

[0030] Control the second battery pack to power the server;

[0031] Alternatively, the first DC conversion circuit is controlled to switch to a power supply mode, so that the first battery pack supplies power to the server.

[0032] In an embodiment of the present application, when the AC mains power supply is abnormal, the second battery pack and the first battery pack are used to preferentially power the server. Compared with the original auxiliary power supply by the second battery pack, the auxiliary power supply of the first battery pack is added, which can provide more power resources for the server in the case of power abnormality, effectively improving the stability of the server operation.

[0033] In combination with the first aspect, in some implementations of the first aspect, the switch circuit includes: a first switch, a second switch, a third switch, and a fourth switch;

[0034] The first switch and the second switch are single-pole double-throw switches, and the third switch and the fourth switch are single-pole single-throw switches;

[0035] The control terminal 1 of the first switch is connected to the first terminal of the third switch, the control terminal 2 is connected to the first terminal of the fourth switch, and the second terminal of the fourth switch is connected to the charging terminal;

[0036] The control terminal 3 of the second switch is connected to the first terminal of the third switch, the control terminal 4 is connected to the first terminal of the fourth switch, and the second terminal of the third switch is connected to the server.

[0037] In an embodiment of the present application, a switching circuit is provided to be composed of a plurality of switches, so that the control method of the switching circuit can be made more diversified through the joint use of the plurality of switches, with more control methods and effects, thereby improving the management scope of the entire power supply management circuit and achieving more active, efficient and diversified management.

[0038] In conjunction with the first aspect, in certain implementations of the first aspect, the control state of the switch circuit includes at least one of the following:

[0039] The first state refers to the third switch being closed, the fourth switch being open, the control terminal 1 being connected, and the control terminal 3 being connected;

[0040] The second state refers to the third switch being disconnected, the fourth switch being closed, and the control terminal 2 being connected;

[0041] The third state refers to the third switch being disconnected, the fourth switch being closed, the control terminal 2 being connected, and the control terminal 4 being connected;

[0042] The fourth state refers to the third switch being disconnected, the fourth switch being disconnected, the control terminal 2 being connected, and the control terminal 4 being connected;

[0043] The fifth state refers to that the third switch is closed, the fourth switch is closed, the control terminal 2 is connected, and the control terminal 3 is connected.

[0044] In the embodiments of the present application, multiple operating states of the switch circuit are set to enable the switch circuit's operating state to be switched promptly and flexibly according to demand, thereby improving the control efficiency and accuracy of the switch circuit. Furthermore, the setting of the operating state allows for more convenient operation and control of the switch circuit, effectively improving the management efficiency of the entire circuit.

[0045] In combination with the first aspect, in some implementations of the first aspect, the switch circuit further includes a fifth switch, a first end of the fifth switch connected to the first end of the third switch, and a second end of the fifth switch connected to the first end of the fourth switch;

[0046] The controller controls the third switch, the fourth switch, and the fifth switch to be turned on, and controls the second battery pack to supply power to the charging terminal.

[0047] Alternatively, the controller may also control the battery pack in the device to be charged of the charging terminal to supply power to the second battery pack.

[0048] In an embodiment of the present application, a fifth switch is added to the switch circuit. The fifth switch is directly connected to the third and fourth switches, while the third switch is connected to the second battery and the fourth switch is connected to the charging terminal. This establishes a connection link from the second battery, the third switch, the fourth switch, and the fifth switch to the charging terminal. This link enables bidirectional management of the second battery pack and the battery in the device to be charged connected to the charging terminal. For example, when the third, fourth, and fifth switches are all turned on, the second battery pack is controlled to supply power to the charging terminal. This more efficiently improves resource utilization.

[0049] In combination with the first aspect, in certain implementations of the first aspect, a second DC conversion circuit is further connected between the switch circuit and the charging terminal;

[0050] When the charging terminal is connected to the device to be charged, the second DC conversion circuit switches to the charging mode to supply power to the charging terminal;

[0051] When the charging terminal is not connected to the device to be charged, the second DC conversion circuit switches to the power supply mode so that the battery pack in the device to be charged supplies power to the server.

[0052] In an embodiment of the present application, a DC conversion circuit, namely, a second DC conversion circuit, is added between the switching circuit and the charging terminal. The second DC conversion circuit has two working modes, namely, a charging mode and a power supply mode. Thus, by controlling the second DC conversion circuit, bidirectional power resource management is achieved, making the use of the second battery pack and the battery pack in the charging device more diversified, further improving the utilization efficiency of power resources and battery packs.

[0053] According to a second aspect of the present application, a power supply control method is provided. The power supply control method can be applied to a controller of a power supply management circuit. The power supply management circuit further includes a first AC-DC conversion circuit, a switching circuit, and a first DC conversion circuit connected in sequence. The first AC-DC conversion circuit is used to connect to the AC mains; the switching circuit is used to connect a second battery pack and a charging terminal. The second battery pack is used to connect to the second AC-DC conversion circuit. The second AC-DC conversion circuit is used to connect to a server and the AC mains to power the server.

[0054] Controlling the switch circuit, the first AC-DC conversion circuit, and the first DC conversion circuit to adjust the operating state of the first battery pack and / or the second battery pack;

[0055] The working state refers to the battery pack being in a charging state or a discharging state. The charging state refers to inputting electrical energy into the battery pack to charge the battery pack, and the discharging state refers to outputting electrical energy to the battery pack to power the load.

[0056] In the embodiment of the present application, the first battery pack, the second battery pack, and the charging terminal are connected via a power management circuit, establishing a relationship between the controller and the other circuits. This allows the controller to control the operation of the switching circuit, the first AC-DC conversion circuit, and the first DC conversion circuit to adjust the operating state of the first and / or second battery packs. By using the first and second battery packs together, the power resources of the first and second battery packs are effectively increased, avoiding waste and idleness of power resources and effectively improving resource utilization efficiency.

[0057] According to a third aspect of the present application, a power supply management device is provided, comprising any power supply management circuit and a first battery pack connected to the power supply management circuit.

[0073] In order to make the purpose, technical solutions and advantages of this application more apparent, the following exemplary embodiments of this application will be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of this application, rather than all the embodiments of this application, and it should be understood that this application is not limited to the exemplary embodiments described herein.

[0074] The technical solution of the present application can be applied to scenarios where digital centers and charging piles are used in combination. By establishing a power supply management circuit located between the digital center and the charging piles, the batteries of the digital center and the batteries of the charging piles can be managed simultaneously through the power supply management circuit, thereby maximizing resource utilization and improving resource management efficiency.

[0075] This embodiment of the present application considers the combined use of additional battery packs configured for data center servers and additional battery packs configured for charging piles, thereby improving battery pack utilization and the efficiency of power resource management. Based on this, the technical solution of this embodiment of the present application is proposed. The technical solution of this embodiment of the present application will be described in detail below with reference to the accompanying drawings.

[0076] Figure 1 A schematic diagram of the structure of a power supply management circuit provided in an embodiment of the present application.

[0077] refer to Figure 1 The power supply management circuit may include: a controller 101 and a first AC / DC conversion circuit 102, a switch circuit 103, and a first DC conversion circuit 104 connected in sequence. The first DC conversion circuit 104 is configured to connect to a first battery pack 105. The first AC / DC conversion circuit 102 is configured to connect to an AC mains 106.

[0078] The controller 101 can be configured to establish communication connections with the first AC / DC conversion circuit 102, the switch circuit 103, and the first DC conversion circuit 104. The first AC / DC conversion circuit 102, the switch circuit 103, and the first DC conversion circuit 104 connected sequentially in the power supply management circuit can mean that the first AC / DC conversion circuit 102 is connected to the switch circuit 103, and the switch circuit 103 is connected to the first DC conversion circuit 104.

[0079] The switch circuit 103 is used to connect the second battery pack 107 and the charging terminal 108. The second battery pack 107 is used to connect to the second AC-DC conversion circuit 109. The second AC-DC conversion circuit is used to connect the server 110 and the AC mains 106 to power the server 110. The charging terminal 108 is used to connect to the device to be charged 111.

[0080] The first battery pack 105, the second battery pack 107, the first AC-DC conversion circuit 102, the second AC-DC conversion circuit 109, the charging terminal 108, the switch circuit 103, and the first DC conversion circuit 102 are each connected to the controller 101 in a signal or communication manner. The controller 101 can send control signals to the first battery pack 105, the second battery pack 107, the first AC-DC conversion circuit 102, the second AC-DC conversion circuit 109, the charging terminal 108, the switch circuit 103, or the first DC conversion circuit 102 to control the operation of each circuit.

[0081] The controller 101 is used to control the operation of the switch circuit 103, the first AC-DC conversion circuit 102, and the first DC conversion circuit 104 to adjust the operating state of the first battery pack 105 and / or the second battery pack 107. The operating state is a charging state or a discharging state. The charging state refers to the input of electrical energy into the battery pack to charge the battery pack, and the discharging state refers to the output of electrical energy from the battery pack to power a load.

[0082] Optionally, the AC mains 106 may convert the AC power into DC power through the second AC / DC conversion circuit 109 , and the converted DC power may be used to power the server 110 .

[0083] Optionally, the charging terminal 108 can be used to connect to the device to be charged 111 to charge the device to be charged 111.

[0084] in, Figure 2 A schematic diagram of the structure of the charging terminal is shown in FIG. Figure 2As shown, the charging terminal 108 may include a charging pile control unit 201, and the charging pile control unit 201 may be in communication connection with the controller 101 for receiving control signals sent by the controller 101. The charging terminal 108 may also include a human-computer interaction unit 202 connected to the charging pile control unit 201, and a power distribution switch and detection circuit unit 203. In addition, the charging terminal 108 may also include a charging gun 204 connected to the power distribution switch and detection circuit unit 203. The charging gun 204 is used to access the device to be charged 111. The power distribution switch and detection circuit unit 203 can also access DC high voltage (the DC high voltage is output by, for example, the connection switch circuit 103 or the second DC conversion circuit 112) to charge the device to be charged 111 through the charging gun 204.

[0085] Among them, the charging pile control unit 201 can implement charging-related control processing, such as detecting whether the charging interface of the charging gun is connected to the device to be charged, payment settlement processing, charging parameter control processing, etc. The human-computer interaction unit 202 can be used to conduct human-computer interaction with users who have charging needs to obtain the user's charging needs, such as selecting four modes: fixed power, fixed time, fixed amount, and automatic (until full); displaying the current charging mode, time (charged time, remaining charging time), power (charged power, to be charged power) and current billing information. The distribution switch and detection circuit unit 203 can be used to improve the protection functions of the charging terminal 108, such as overvoltage protection, undervoltage protection, overload protection, short circuit protection, leakage protection and other functions. In the embodiment of the present application, the specific structure and function of each unit in the charging terminal 108 are not excessively limited.

[0086] An alternating current / direct current (AC / DC) conversion circuit (such as the first AC / DC conversion circuit or the second AC / DC conversion circuit) may refer to a circuit that converts alternating current (AC) into direct current (DC).

[0087] A direct current to direct current (DC / DC) converter circuit (such as the first DC converter circuit or the second DC converter circuit) can be a circuit that converts DC to DC, primarily used to adjust parameters such as DC voltage and current. A DC converter circuit can have two operating modes: charging mode and power supply mode.

[0088] The charging mode may refer to the output current of the DC conversion circuit flowing into the battery pack to charge the battery pack.

[0089] The discharge mode may refer to the current of the battery pack flowing into the DC conversion circuit, and the battery pack supplies power to the external load.

[0090] Optionally, the server 110 may refer to a server node in a data center. In the embodiments of the present application, the number and type of servers are not excessively limited and will not be described in detail here.

[0091] For example, server 110 may be IT (Information Technology) equipment. AC mains 106 supplies power to server 110 via second AC / DC converter circuit 109 . Second AC / DC converter circuit 109 may be, for example, a UPS (Uninterruptible Power Supply) or HVDC (High Voltage Direct Current) system.

[0092] In the embodiment of the present application, the controller is connected to a first AC / DC conversion circuit, a switch circuit, and a first DC conversion circuit in sequence; the first DC conversion circuit is connected to the first battery pack, and the first AC / DC conversion circuit is connected to the AC mains; the switch circuit is also connected to the second battery pack and the charging terminal, the second battery pack is connected to the second AC / DC conversion circuit, and the second AC / DC conversion circuit is connected to the server to power the server; the first battery pack 105, the second battery pack 107, the first AC / DC conversion circuit 102, the second AC / DC conversion circuit 109, the charging terminal 108, the switch circuit 103, and the first DC conversion circuit 102 are respectively signal-connected to the controller 101; the first battery pack, the second battery pack, and the charging terminal are connected through the power management circuit, establishing an association between the controller and other circuits, so that the switch circuit, the first AC / DC conversion circuit, and the first DC conversion circuit can be operated and controlled by the controller to achieve the purpose of adjusting the working state of the first battery pack and / or the second battery pack. By using the first battery pack and the second battery pack together, the power resources of the first battery pack and the second battery pack are effectively improved, avoiding waste and idleness of power resources, and effectively improving resource utilization efficiency.

[0093] As described above, the controller 101 can control the switch circuit 103 , the first AC-DC conversion circuit, and the first DC conversion circuit 104 to perform operation control to adjust the working state of the first battery pack 105 and / or the second battery pack 107 .

[0094] Specifically, the controller 101 may adjust the working state of the first battery pack 105 and / or the second battery pack 107 through the following operation control methods.

[0095] Case 1: When the controller determines that the server is not operating at peak load and the charging terminal is not connected to a device to be charged, the controller is specifically configured to perform the following operations:

[0096] A1, control the first AC-DC conversion circuit to charge the second battery pack and / or control the first DC conversion circuit to switch to a charging mode to charge the first battery pack.

[0097] Whether a server is operating at peak load can be determined by whether the server's load power is greater than a predetermined peak value. The load power specifically refers to the power required by the server to process user traffic. For example, assuming the predetermined peak value is 100 kW, if the server's load power is 120 kW, which is greater than 100 kW, the server is determined to be operating at peak load. If the server's load power is 90 kW, which is less than 100 kW, the server is determined not to be operating at peak load.

[0098] Of course, whether the server is operating at peak load can be determined by whether the server's load power is greater than a predetermined peak value within a certain period of time. That is, if the server's load power is greater than the predetermined peak value within a certain period of time, then the server is determined to be operating at peak load. If the server's load power is less than or equal to the predetermined peak value within a certain period of time, then the server is determined not to be operating at peak load.

[0099] The load power of a server within a certain time period may refer to the maximum power or average power consumed by the server within the certain time period. In addition to the maximum power or average power consumed within the certain time period, the load power of a server within the certain time period may also be determined comprehensively based on the usage of the server's hardware resources. The calculation method of the load power is not excessively limited in the embodiments of the present application.

[0100] Case 2: When the controller determines that the server is not operating at peak load and the charging terminal is connected to a device to be charged, the controller is specifically configured to perform the following operations:

[0101] A2, controlling the first AC-DC conversion circuit to supply power to the charging terminal.

[0102] A3. If the device to be charged requires fast charging, the first DC conversion circuit is controlled to switch to the power supply mode so that the first battery pack supplies power to the charging terminal, and / or the second battery pack is controlled to supply power to the charging terminal, and / or when the remaining power of the first battery pack is less than the first threshold value, the first battery pack is controlled to stop supplying power to the charging terminal.

[0103] A4. If the charging device has finished charging, control the first DC conversion circuit to switch to a charging mode to charge the first battery pack.

[0104] In this embodiment, when the server is not operating at peak load, the controller limits the operations it performs in different scenarios, taking into account whether the charging terminal is connected to a device to be charged. This allows the first and second battery packs to complete charging in a timely manner, and after the charging terminal is connected to the device to be charged, it charges the device in different charging modes based on the device's needs. This balances the needs of high resource utilization and fast charging, effectively improving the operational and management efficiency of the entire system.

[0105] Case 3: When the controller determines that the server is not operating at peak load and the charging terminal is not connected to the device to be charged, the controller is specifically configured to perform any one of the following operations:

[0106] B1. Control the second battery pack to supply power to the server and control the first AC / DC conversion circuit to supply power to the second battery pack to replenish power of the second battery pack.

[0107] B2. If it is determined that the remaining power of the second battery pack is greater than the second threshold value, the first DC conversion circuit is controlled to stop working so that the first battery pack does not work.

[0108] B3. If it is determined that the remaining power of the second battery pack is less than or equal to the second threshold value, control the first DC conversion circuit to switch to the power supply mode so that the first battery pack supplies power to the server.

[0109] B4, controlling the first DC conversion circuit to switch to a power supply mode, so that the first battery pack supplies power to the server.

[0110] Case 4: When the controller determines that the server is not operating at peak load and the charging terminal is connected to a device to be charged, the controller is specifically configured to perform any one of the following operations:

[0111] B5, control the second battery pack to supply power to the server, and / or, when the remaining power of the second battery pack is greater than the first threshold value, control the first DC conversion circuit to stop working so that the first battery pack does not work, and / or, when the remaining power of the second battery pack is less than or equal to the first threshold value, control the first DC conversion circuit to switch to the power supply mode so that the first battery pack supplies power to the server.

[0112] B6, controlling the first AC-DC conversion circuit to supply power to the charging device.

[0113] In this embodiment, when the server is operating at peak load, the controller's corresponding operations are limited based on different scenarios, depending on whether the charging terminal is connected to the device to be charged. This prioritizes ensuring the server's power needs, while also improving the charging efficiency of the device to be charged. This allows for efficient management of the operating status of the first and second battery packs, further improving the operational and management efficiency of the entire system.

[0114] Both Case 1 and Case 2 are based on the normal operation of the AC mains 106. If the AC mains 106 is abnormally operating, the situation falls under the following Case 3.

[0115] Case 5: The AC mains power supply is abnormal. Regardless of whether the server is operating at peak load, the controller performs the following operations:

[0116] C1. Control the second battery pack to supply power to the server, and / or control the first DC conversion circuit to switch to a power supply mode so that the first battery pack supplies power to the server.

[0117] In an embodiment of the present application, when the AC mains power supply is abnormal, the second battery pack and the first battery pack are used to preferentially power the server. Compared with the original auxiliary power supply by the second battery pack, the auxiliary power supply of the first battery pack is added, which can provide more power resources for the server in the case of power abnormality, effectively improving the stability of the server operation.

[0118] In some possible designs, the battery in the device to be charged can also be used as a backup battery to power the server. In order to solve the problem of switching between the power supply and charging state of the device to be charged, a DC conversion circuit can be set between the switch circuit and the charging terminal. The DC conversion circuit can control the direction of the current, thereby realizing the state switching problem of the device to be charged. Based on this, a method is proposed as follows Figure 3 The schematic diagram of a power supply management circuit shown in FIG. Figure 1 The differences of the power management circuit shown are:

[0119] The switch circuit 103 may also be connected to the second DC conversion circuit 112 , and the second DC conversion circuit 112 may also be connected to the charging terminal 108 .

[0120] Optionally, the second DC conversion circuit 112 may be a bidirectional DC / DC, that is, it may supply power to the device to be charged 111 connected to the charging terminal 108 , or the battery in the device to be charged 111 may supply power to the server 110 .

[0121] In an embodiment of the present application, a DC conversion circuit, i.e., a second DC conversion circuit, is added between the switching circuit and the charging terminal. The second DC conversion circuit has two working modes, i.e., a charging mode and a power supply mode. Thus, in combination with whether the charging terminal is connected to the device to be charged, bidirectional control of the second DC conversion circuit is achieved, i.e., control of the working state of the battery pack in the device to be charged is achieved. Through bidirectional power resource management, the usage of the battery pack in the device to be charged is made more diversified, thereby further improving the utilization efficiency of power resources and battery packs.

[0122] In some possible designs, the switch circuit 103 may be composed of multiple switches to achieve control switching of the working states of the first battery pack 105 and the second battery pack 107 .

[0123] under Figure 4 A schematic diagram of the structure of another power supply management circuit is shown, which differs from the previous embodiment in that:

[0124] The switch circuit 103 may include a first switch 1031 , a second switch 1032 , a third switch 1033 , and a fourth switch 1034 .

[0125] The first switch 1031 and the second switch 1032 are single-pole double-throw switches, and the third switch 1033 and the fourth switch 1034 are single-pole single-throw switches.

[0126] The control terminal 1 of the first switch 1031 is connected to the first terminal of the third switch, the control terminal 2 is connected to the first terminal of the fourth switch, and the second terminal of the fourth switch is connected to the charging terminal;

[0127] The control terminal 3 of the second switch is connected to the first terminal of the third switch, the control terminal 4 is connected to the first terminal of the fourth switch, and the second terminal of the third switch is connected to the server.

[0128] In an embodiment of the present application, a switching circuit is provided to be composed of a plurality of switches, so that the control method of the switching circuit can be made more diversified through the joint use of the plurality of switches, with more control methods and effects, thereby improving the management scope of the entire power supply management circuit and achieving more active, efficient and diversified management.

[0129] As described above, the controller 101 may control the switch circuit 103 to adjust the operating state of the first battery pack 105 and / or the second battery pack 107. Specifically, the operating state of the switch circuit 103 may include but is not limited to at least one of the following:

[0130] The first state means that the third switch is closed, the control terminal 1 is connected, and the control terminal 3 is connected.

[0131] The second state means that the third switch is disconnected, the fourth switch is closed, and the control terminal 2 is connected.

[0132] The third state means that the third switch is disconnected, the fourth switch is closed, the control terminal 2 is connected, and the control terminal 4 is connected.

[0133] The fourth state refers to that the fourth switch is disconnected.

[0134] The fifth state refers to that the third switch is closed, the control terminal 2 is connected, and the control terminal 3 is connected.

[0135] In the embodiments of the present application, multiple operating states of the switch circuit are set to enable the switch circuit's operating state to be switched promptly and flexibly according to demand, thereby improving the control efficiency and accuracy of the switch circuit. Furthermore, the setting of the operating state allows for more convenient operation and control of the switch circuit, effectively improving the management efficiency of the entire circuit.

[0136] In combination with the above-mentioned situation 1 and situation 2 and the control method of the controller 101 on the switch circuit 103, the embodiment of the present application provides the following embodiments:

[0137] Embodiment 1: The controller controls the switch circuit to operate in the first state and executes A1.

[0138] The server is not operating at peak load and the charging terminal is not connected to the device to be charged. The controller can control the control terminal 1 to be turned on and the third switch to be closed, and control the first AC-DC conversion circuit to charge the second battery pack.

[0139] During the charging process, the controller controls the output voltage of the first AC-DC conversion circuit to be higher than the voltage of the second battery pack, so that the current output by the first AC-DC conversion circuit charges the second battery pack.

[0140] In a possible design, the controller may further control the control terminal 3 to be turned on, and control the first DC conversion circuit to switch to a charging mode to charge the first battery pack.

[0141] In another possible design, to prioritize the stability of the data center's power supply, the second battery pack can be charged first. During the charging process, the second battery pack's charge level can be monitored. When the second battery pack is fully charged, the first DC converter circuit is controlled to switch to charging mode to charge the first battery pack.

[0142] Optionally, after the first battery pack is fully charged and / or the second battery pack is fully charged, the system may enter a standby state, that is, the first AC-DC conversion circuit and the first DC conversion circuit no longer operate.

[0143] Embodiment 2: The controller controls the switch circuit to operate in the second state and executes A2.

[0144] The server is not operating at peak load and the charging terminal is connected to the device to be charged. The controller controls the third switch to be disconnected, the control terminal 2 to be connected, and the fourth switch to be closed, so that the first AC-DC conversion circuit supplies power to the charging terminal.

[0145] Optionally, when the AC / DC circuit supplies power to the charging terminal, the controller can determine the voltage and current required by the charging terminal, and send the voltage required by the charging terminal as the output voltage and the current as the output current to the first AC / DC conversion circuit, so that the voltage and current output by the first AC / DC conversion circuit meet the usage requirements of the charging terminal.

[0146] It can also be understood that in order to ensure the safety of the circuit, the controller can first send the output voltage and output current to the first AC-DC conversion circuit before controlling the fourth switch to close the loop, and after determining that the output voltage and output current adjustment of the first AC-DC conversion circuit are completed, control the fourth switch to close, so as to avoid component loss due to excessive difference between charging and discharging voltages and improve the stability of circuit operation.

[0147] Embodiment 3: The controller controls the switch circuit to operate in the third state and executes A3.

[0148] If the server is not operating at peak load and the charging terminal is connected to the device to be charged, the controller controls control terminal 2 to be turned on and the fourth switch to be closed, so that the first AC-DC conversion circuit supplies power to the charging terminal. If the device to be charged requires fast charging, the controller can control control terminal 4 to be turned on and the fourth switch to be closed, and control the first DC conversion circuit to switch to power supply mode so that the first battery pack supplies power to the charging terminal.

[0149] In order to further improve the charging efficiency, the third switch and the fifth switch may be controlled to be turned on so that the second battery pack supplies power to the charging terminal 108 .

[0150] In order to ensure the power supply stability of the data center, when the first battery pack is supplying power to the charging terminal, the remaining power of the first battery pack can be detected. If the remaining power of the first battery pack is less than the first threshold value, the control terminal 4 is controlled to be disconnected, and the first DC conversion circuit is controlled to stop working, so as to control the first battery pack to stop supplying power to the charging terminal.

[0151] When the first battery pack stops supplying power to the charging terminal, the first AC-DC conversion circuit is retained to supply power to the charging terminal, thereby ensuring the charging continuity of the charging terminal when the charging terminal is connected to the device to be charged, and avoiding the phenomenon of charging failure of the device to be charged due to the termination of power supply by the first battery pack.

[0152] Embodiment 4: The controller controls the switch circuit to operate in the fourth state and executes A4.

[0153] If both the DC conversion circuit and the first battery pack are powered by the charging terminal, the controller can monitor the charging mode of the device to be charged. The charging mode can include, for example, one or more states: charging, charging completed, connected to the charging terminal but not charging started, etc. Specifically, the controller can communicate with the device to be charged or the charging terminal to obtain the charging mode of the device to be charged.

[0154] When the controller determines that the charging of the device to be charged is completed, the fourth switch may be turned off, and the first DC conversion circuit may be controlled to switch to a power supply mode to charge the first battery pack.

[0155] Embodiment 5: The controller controls the switch circuit to operate in the first state and executes any one or more embodiments of B1, B2, B3 or B4.

[0156] When the server is operating at peak load and the charging terminal is not connected to a device to be charged, the controller can control the second battery pack to power the server.

[0157] As an embodiment, when the second battery is powering the server, the controller can control the control terminal 1 to be turned on and the third switch to be closed, and control the first AC-DC conversion circuit to charge the second battery pack, thereby replenishing power resources for the second battery pack.

[0158] As another embodiment, in addition to controlling the second battery pack to power the server and controlling the first AC / DC conversion circuit to charge the second battery pack, the controller may also execute:

[0159] If the controller determines that the remaining power of the second battery pack is greater than the second threshold value, the controller controls the first DC conversion circuit to stop working, so that the first battery pack does not supply power to the server.

[0160] As another embodiment, in addition to controlling the second battery pack to power the server and controlling the first AC / DC conversion circuit to charge the second battery pack, the controller may also execute:

[0161] If the controller determines that the remaining power of the second battery pack is less than or equal to the second threshold value, the controller controls the control terminal 3 to be turned on and the third switch to be closed, and controls the first DC conversion circuit to switch to the power supply mode so that the first battery pack can power the server.

[0162] As another embodiment, in addition to conditionally controlling the first battery pack to power the server, the server can also be powered unconditionally. That is:

[0163] When the server is operating at peak load and the charging terminal is not connected to the device to be charged, the controller can control the control terminal 3 to be turned on and the third switch to be closed, and control the first DC conversion circuit to switch to the power supply mode so that the first battery pack can power the server.

[0164] Embodiment 6: The controller controls the switch circuit to operate in the fifth state and executes B5 or B6.

[0165] The server is operating at peak load and the charging terminal is connected to the device to be charged. In order to solve the problem of large power demand of the server, the switch circuit can be controlled to operate in the fifth state, so that the first AC-DC conversion circuit can provide regular charging for the device to be charged, and can be combined with the first battery pack and the second battery pack to provide additional power to the server.

[0166] As an embodiment, the controller may control the first AC-DC conversion circuit to supply power to the charging device.

[0167] As yet another embodiment, the controller may control the second battery pack to supply power to the server.

[0168] As another embodiment, the controller can also monitor the power of the second battery pack. If the remaining power of the second battery pack is greater than the third threshold value, the first DC conversion circuit can be controlled to stop working, so that the first battery pack does not work and temporarily does not power the server.

[0169] As another embodiment, if the remaining power of the second battery pack is less than or equal to the third threshold value, the first DC conversion circuit may be controlled to switch to a power supply mode so that the first battery pack supplies power to the server.

[0170] Embodiment 7: The controller controls the switch circuit to operate in the first state and executes C1.

[0171] That is, when the AC mains power supply is abnormal, regardless of whether the server is operating at peak load, the controller controls the second battery pack to power the server, and / or controls the first DC conversion circuit to switch to power supply mode so that the first battery pack can power the server.

[0172] In one possible design, if the service center's power demand is low, the second battery pack can be controlled to power the charging terminal, thereby providing more power resources to the charging terminal and improving the charging efficiency of the device being charged. To connect the second battery pack 107 to the charging terminal 108, a new switch can be added to the switch circuit 103. When the new switch is turned on, the second battery pack 107 can power the charging terminal 108. If the new switch is turned off, the second battery pack 107 is disconnected from the charging terminal 108 and cannot power the charging terminal 108.

[0173] Figure 5 A structural diagram of another power supply management device of the present application is shown, which is different from the above-mentioned embodiment in that the switch circuit 103 can also include a fifth switch 1035, a first end of the fifth switch is connected to the third switch, and a second end is connected to the fourth switch.

[0174] It is understandable that the controller 101 can control the third switch 1033 , the fifth switch 1035 and the fourth switch 1034 to be connected, so that the second battery pack 107 supplies power to the charging terminal 108 .

[0175] However, if the voltage output by the second battery pack 107 is inconsistent with the voltage at the input of the charging terminal 108, the input voltage of the charging terminal 108 may be too high, causing component damage and overheating of the charging terminal 108. To solve this problem, a second DC conversion circuit 112 can be added between the switching circuit and the charging terminal.

[0176] refer to Figure 5 The fourth switch 1034 can also be used to connect to the second DC conversion circuit 112, the second DC conversion circuit 112 is used to connect to the charging terminal 108, and the charging terminal 108 is used to access the device to be charged 111.

[0177] The controller 101 controls the third switch 1033, the fifth switch 1035, and the fourth switch 1034 to be connected, and can also control the second DC conversion circuit 112 to be in power supply mode to power the charging terminal 108. Specifically, it can charge the battery pack on the device to be charged 111 connected to the charging terminal 108.

[0178] The controller 101 controls the third switch 1033, the fifth switch 1035 and the fourth switch 1034 to be connected, and can also simultaneously control the second DC conversion circuit 112 to be in charging mode, so that the battery pack of the device to be charged 111 charges the second battery pack 107 through the charging terminal 108 and the second DC conversion circuit 112.

[0179] like Figure 6 As shown, a flow chart of a power supply control method provided in an embodiment of the present application is provided. The power supply control method is applied to a controller of a power supply management circuit. The power supply management circuit further includes a first AC-DC conversion circuit, a switching circuit, and a first DC conversion circuit connected in sequence; the first DC conversion circuit is used to connect to a first battery pack, and the first AC-DC conversion circuit is used to connect to an AC mains; the switching circuit is used to connect a second battery pack and a charging terminal, the second battery pack is used to connect to a second AC-DC conversion circuit, the second AC-DC conversion circuit is used to connect to a server and an AC mains to power the server, and the charging terminal is used to access a device to be charged; the method includes:

[0180] S601. Control the switching circuit, the first AC-DC conversion circuit, and the first DC conversion circuit of the power supply management circuit to adjust the working state of the first battery pack and / or the second battery pack; wherein the working state refers to the battery pack being in a charging state or a discharging state, the charging state refers to inputting electrical energy into the battery pack to charge the battery pack, and the discharging state refers to the battery pack outputting electrical energy to power the load.

[0181] In the embodiment of the present application, the first battery pack, the second battery pack, and the charging terminal are connected via a power management circuit, establishing a relationship between the controller and the other circuits. This allows the controller to control the operation of the switching circuit, the first AC-DC conversion circuit, and the first DC conversion circuit to adjust the operating state of the first and / or second battery packs. By using the first and second battery packs together, the power resources of the first and second battery packs are effectively increased, avoiding waste and idleness of power resources and effectively improving resource utilization efficiency.

[0182] The power supply control method in the embodiment of the present application may further include:

[0183] When it is determined that the server is not operating at peak load and the charging terminal is not connected to the device to be charged, the first AC-DC conversion circuit is controlled to charge the second battery pack and / or the first DC conversion circuit is controlled to switch to charging mode to charge the first battery pack.

[0184] Further, based on any of the above embodiments, when it is determined that the server is not operating at peak load and the charging terminal is connected to the device to be charged, at least one of the following items is also included:

[0185] controlling the first AC-DC conversion circuit to supply power to the charging terminal;

[0186] Alternatively, if it is detected that the device to be charged has a fast charging demand, the first DC conversion circuit is controlled to switch to a power supply mode so that the first battery pack supplies power to the charging terminal, and / or the second battery pack is controlled to supply power to the charging terminal, and / or when the remaining power of the first battery pack is less than a first threshold value, the first battery pack is controlled to stop supplying power to the charging terminal;

[0187] Alternatively, if it is detected that the charging of the device to be charged is completed, the first DC conversion circuit is controlled to switch to the charging mode to charge the first battery pack.

[0188] In this embodiment, when the server is not operating at peak load, the controller limits the operations it performs in different scenarios, taking into account whether the charging terminal is connected to a device to be charged. This allows the first and second battery packs to complete charging in a timely manner, and after the charging terminal is connected to the device to be charged, it charges the device in different charging modes based on the device's needs. This balances the needs of high resource utilization and fast charging, effectively improving the operational and management efficiency of the entire system.

[0189] Furthermore, based on any of the above embodiments, when it is determined that the server is operating at peak load and the charging terminal is not connected to the device to be charged, the power supply control method in the embodiment of the present application may further include at least one of the following:

[0190] Controlling the second battery pack to supply power to the server and controlling the first AC / DC conversion circuit to charge the second battery pack;

[0191] Alternatively, if it is determined that the remaining power of the second battery pack is greater than the second threshold value, the first DC conversion circuit is controlled to stop working so that the first battery pack does not supply power to the server;

[0192] Alternatively, if it is determined that the remaining power of the second battery pack is less than or equal to the second threshold value, controlling the first DC conversion circuit to switch to the power supply mode so that the first battery pack supplies power to the server;

[0193] Alternatively, controlling the first DC conversion circuit to switch to a power supply mode so that the first battery pack supplies power to the server;

[0194] When the controller determines that the server is operating at peak load and the charging terminal is connected to a device to be charged, the power supply control method in the embodiment of the present application may further include at least one of the following:

[0195] Control the second battery pack to power the server;

[0196] Alternatively, if the remaining power of the second battery pack is greater than a third threshold value, the first DC conversion circuit is controlled to stop working, so that the first battery pack does not work;

[0197] Alternatively, if the remaining power of the second battery pack is less than or equal to the first threshold value, controlling the first DC conversion circuit to switch to the power supply mode so that the first battery pack supplies power to the server;

[0198] Alternatively, the first AC-DC conversion circuit is controlled to supply power to the charging device.

[0199] In this embodiment, when the server is operating at peak load, the controller's corresponding operations are limited based on different scenarios, depending on whether the charging terminal is connected to the device to be charged. This prioritizes ensuring the server's power needs, while also improving the charging efficiency of the device to be charged. This allows for efficient management of the operating status of the first and second battery packs, further improving the operational and management efficiency of the entire system.

[0200] Furthermore, based on any of the above embodiments, the power supply control method in the embodiment of the present application may further include:

[0201] If an abnormal AC mains power supply is detected, the second battery pack is controlled to supply power to the server, or the first DC conversion circuit is controlled to switch to a power supply mode so that the first battery pack supplies power to the server.

[0202] In an embodiment of the present application, when the AC mains power supply is abnormal, the second battery pack and the first battery pack are used to preferentially power the server. Compared with the original auxiliary power supply by the second battery pack, the auxiliary power supply of the first battery pack is added, which can provide more power resources for the server in the case of power abnormality, effectively improving the stability of the server operation.

[0203] Furthermore, based on any of the above embodiments, a second DC conversion circuit is further connected between the switch circuit and the charging terminal; the power supply control method in the embodiment of the present application may further include:

[0204] If it is detected that the charging terminal is connected to the device to be charged, the second DC conversion circuit is controlled to switch to the charging mode to supply power to the charging terminal;

[0205] Alternatively, if it is detected that the charging terminal is not connected to the device to be charged, the second DC conversion circuit is controlled to switch to the power supply mode, so that the battery pack in the device to be charged supplies power to the server.

[0206] In an embodiment of the present application, a DC conversion circuit, i.e., a second DC conversion circuit, is added between the switching circuit and the charging terminal. The second DC conversion circuit has two working modes, i.e., a charging mode and a power supply mode. Thus, in combination with whether the charging terminal is connected to the device to be charged, bidirectional control of the second DC conversion circuit is achieved, i.e., control of the working state of the battery pack in the device to be charged is achieved. Through bidirectional power resource management, the usage of the battery pack in the device to be charged is made more diversified, thereby further improving the utilization efficiency of power resources and battery packs.
