[0022] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0023] The embodiments of this application will now be described with reference to the accompanying drawings.

[0024] Figure 1 This is a schematic diagram of the structure of an energy storage power supply device for a data center according to one embodiment of this application, as shown below. Figure 1As shown, the energy storage power supply device for data centers according to an embodiment of this application includes a power supply equipment layer, a pattern recognition module, a control module, and at least one energy storage battery, wherein:

[0025] The pattern recognition module is connected to the input port of the power equipment layer to detect the mode status of the input voltage of the power equipment layer. The input voltage can adopt a master-slave mode, that is, a master input voltage and a bypass input voltage. In the data center, intelligent management can be achieved by centrally monitoring the master input voltage and distributing the bypass input voltage, which can reduce energy consumption and improve the reliability of the data center.

[0026] The control module connects to the output terminals of the power supply layer and the pattern recognition module. Based on the mode status, it adjusts the power transmission mode of the power supply layer. Each energy storage battery is connected to the power supply layer and the control module. If the mode status is normal mains power, the input voltage of the power supply layer is the mains voltage (this mains voltage varies from 100V to 380V; data center server rooms generally use three-phase 380V mains power, but some equipment power rectifier modules typically use single-phase 220V voltage; the type of mains power should be selected according to the specific usage scenario). The control module adjusts the mains voltage to supply power to the load at the output port of the power supply layer and to charge the depleted energy storage batteries. Power supply to the load should be ensured first. If there is a margin, the depleted energy storage batteries can be charged. The charging time and charging power can be set according to pre-set instructions. If the data center is deployed in the cloud, instructions can be issued through the cloud. If the mains power is normal and the energy storage battery needs to be discharged, the discharge operation can be performed according to the instructions issued by the cloud or the built-in charging and discharging strategy of the energy storage battery. The control module can shut off the input port of the power equipment layer (i.e., the input voltage is disconnected), and then the control module adjusts at least one energy storage battery to supply power to the load at the output port of the power equipment layer. If the capacity of the energy storage battery reaches the preset value or the required discharge time is reached, the control module can disconnect the power path from the energy storage battery to the output port of the power equipment layer and switch back to supplying power to the load by the input voltage of the power equipment layer.

[0027] If the mode status indicates a mains power failure, the control module shuts off the input ports of the power supply layer and adjusts at least one energy storage battery to supply power to the load at the output port of the power supply layer. If the voltage of the energy storage battery drops to the discharge cutoff voltage, and the main input voltage in the input voltage does not return to normal, the load can be powered through the bypass input voltage. If the bypass input voltage shows an abnormality, the energy storage power supply device will shut down and disconnect power.

[0028] Optionally, as an example, such as Figure 1As shown, the power supply equipment layer includes a main input port, a bypass input port, an output port, a main switch, a bypass switch, a maintenance switch, a load switch, a static bypass component, at least one rectifier, and at least one inverter. Both the main input port and the bypass input port are connected to input voltage. The main input port is connected to the main input voltage for centralized monitoring of the data center, while the bypass input port is connected to the bypass input voltage for distributed execution of the data center.

[0029] like Figure 1 As shown, the main circuit switch is connected to the main circuit input port and the control module. When the mains power is normal and the energy storage battery does not need to be discharged, the control module adjusts the main circuit switch to the open state; when the mains power is normal and the energy storage battery needs to be discharged, the control module adjusts the main circuit switch to the closed state; when the mains power is abnormal, the control module adjusts the main circuit switch to the closed state.

[0030] like Figure 1 As shown, the bypass switch is connected to the bypass input port and the control module. When the mains power is abnormal, the control module adjusts at least one energy storage battery to supply power to the load at the output port of the power equipment layer. If the voltage of the energy storage battery drops to the discharge cutoff voltage and the main input voltage in the input voltage does not return to normal, the load can be supplied with power through the bypass input voltage. If the bypass input voltage shows an abnormality, the energy storage power device will be shut down and power will be cut off. The static bypass component is connected to the bypass switch. Also known as the emergency path, the static bypass component is a path that directly transfers electrical energy to the load without any conversion. It can be composed of static switches such as three-phase bidirectional thyristor switches. When the main input port requires maintenance or the overload time exceeds the inverter's output capacity, the static bypass component can switch the load to the path of the bypass input port, thereby isolating the inverter and providing a direct AC bypass power supply to the load. This mode of supplying power to the load through the bypass input port is called ECO mode, short for Economic Control Operation. This mode can be set through the cloud interface of the data center. If the bypass input voltage operates within the voltage and frequency range of ECO mode and meets the power supply conditions of ECO mode, the energy storage power supply prioritizes bypass output, and the inverter is in standby mode. If the bypass input voltage is not within the voltage and frequency range of ECO mode, the inverter is in power supply mode. In ECO mode, the energy storage power supply device can achieve higher power efficiency.

[0031] like Figure 1As shown, the maintenance switch is connected in parallel with the bypass switch and the static bypass component. When maintaining or repairing the energy storage power device, the load can be switched to maintenance mode by closing the maintenance switch. That is, the bypass input voltage is connected to the bypass input port, and then the power is transmitted to the load through the maintenance switch and the load switch, which can ensure that the load continuously receives power.

[0032] like Figure 1 As shown, the load switch is connected to the static bypass component; the number of rectifiers and inverters is equal to the number of energy storage batteries. Each rectifier is connected to the main circuit switch, and each inverter is connected to its corresponding rectifier; the output port is connected to the load switch. It should be noted that if the energy storage batteries need to be fully discharged under load, the energy storage power supply operates in battery mode. If the energy storage batteries reach the predetermined discharge time or capacity, or if the mains power is restored after a power outage, the energy storage power supply switches back to mains power supply, ensuring a continuous flow of energy to the load. If the mains power outage is prolonged, and the energy storage batteries reach the predetermined discharge time or capacity, the energy storage power supply can use a diesel generator to supply power to the main circuit input port and the bypass input port.

[0033] Alternatively, as an example, Figure 2 This is a schematic diagram of the structure of a pattern recognition module according to an embodiment of this application. Figure 2 As shown, the pattern recognition module includes a measurement unit and a judgment unit. The measurement unit is connected to the input port of the power supply layer to detect the status of the bypass input voltage and the main input voltage. The judgment unit is connected to the measurement unit and identifies the pattern status of the input voltage based on a preset configuration. Specifically, the judgment unit can be configured as a digital signal processor, a field-programmable gate array (FPGA), or an ARM processor.

[0034] It should be noted that this measurement unit can detect the amplitude, waveform, and other characteristics of the bypass input voltage and the main input voltage, and identify whether it is DC voltage, AC voltage, or other specific types of voltage. Based on the identified voltage pattern, the measurement unit will output a corresponding feedback signal so that the judgment unit can take appropriate measures. When the bypass input voltage and the main input voltage are abnormal or exceed the load capacity, the measurement unit can respond promptly and drive the judgment unit to identify the mode status of the input voltage, thereby allowing the control module to adjust the power transmission mode of the power supply equipment layer.

[0035] It should be further noted that the pattern recognition module can also be configured using Application Specific Integrated Circuits (ASICs, which are integrated circuits designed and manufactured for specific user requirements and systems; in this embodiment, the integrated circuit represents a stability detection circuit), IP cores (intelligent property cores, which are mature designs of circuit modules with independent functions in chip or integrated circuit designs; these circuit designs can be applied to other chip or integrated circuit design projects that include the circuit module, thereby reducing the design workload, shortening the design cycle, and improving the success rate of chip or integrated circuit design; IP cores are classified into three levels: behavioral, structural, and physical, thus corresponding to three types of IP cores: soft cores designed with hardware description languages, solid cores that complete structural descriptions, and hard cores based on physical descriptions and verified by the process), etc. The specific configuration methods will not be elaborated here. As long as the mode state of the input voltage of the power supply layer can be detected, any configuration method of the pattern recognition module is applicable and is not limited to this embodiment.

[0036] Alternatively, as an example, Figure 3 This is a schematic diagram of the structure of a control module according to an embodiment of this application. Figure 3 As shown, the control module includes a parsing unit, a first adjustment unit, and a second adjustment unit. The parsing unit is connected to the pattern recognition module and is used to parse the pattern state and convert it into a form that the first and second adjustment units can understand and process. The first adjustment unit is connected to the parsing unit and the power equipment layer connector, i.e., the first adjustment unit is connected to the main switch (i.e., the bypass switch), and regulates the on / off states of the main switch and bypass switch in the power equipment layer. Specifically, the first adjustment unit includes relays, thyristors, switching diodes, etc. The second adjustment unit is connected to the parsing unit and each energy storage battery, and regulates the on / off states of the energy storage batteries. Specifically, the second adjustment unit includes a configuration subunit, a monitoring subunit, and a power conversion subunit. The configuration subunit, monitoring subunit, and power conversion subunit are not integrated into the main control module. Figure 3 The diagram shows that the configuration subunit is used to set the charging and discharging parameters of the energy storage battery, such as the predetermined discharge time or predetermined capacity setting value of the energy storage battery. The configuration subunit also synchronizes the communication data of the energy storage battery. The monitoring subunit is used to monitor the status of the energy storage battery in real time, such as battery capacity and voltage. The power conversion subunit is used to adjust the charging and discharging power of the energy storage battery.

[0037] It should be noted that the control module can also be configured using dedicated integrated circuits, IP cores, etc. The specific configuration methods will not be elaborated here. As long as the power transmission mode of the power supply device layer can be adjusted based on the mode state, any configuration method of the control module is applicable and is not limited to this embodiment.

[0038] Optionally, as an example, such as Figure 1 As shown, the energy storage batteries include lithium iron phosphate batteries, lithium manganese oxide batteries, and ternary lithium batteries, with operating voltages ranging from 715V to 936V. It should be noted that the energy storage batteries and the control module can communicate via CAN, and are regulated by the second adjustment unit of the control module.

[0039] In summary, this application incorporates a pattern recognition module at the input port of the power supply layer. By detecting the mode state of the input voltage of the power supply layer, the control module adjusts the power transmission mode of the power supply layer according to the mode state, significantly improving the efficiency of responding to load changes. Furthermore, it balances the power supply at the output port of the power supply layer based on sudden changes in input voltage, maximizing the conservation of power resources and expanding the application scope of energy storage systems, thus demonstrating broad applicability.

[0040] In particular, according to the embodiments of this application, the energy storage power supply device for data centers mentioned above can be implemented as an energy storage system.
