[0057] The energy storage valve expansion device plays a crucial role as a "communication bridge" in DC converter valve stations. It communicates with the valve tower submodule, receives data from each power module, processes it, and transmits it to the master control unit. However, due to technical limitations, existing energy storage valve expansion devices require outages to replace and repair faulty boards, which presents inconveniences.

[0058] In order to solve the above technical problems, an embodiment of the present application provides an expansion device. As shown in Figure 1, the expansion device in this embodiment includes: a VPX backplane 100, at least one power board 200, at least one management board 300, and at least one communication board 400.

[0059] In this embodiment, the VPX backplane 100 is provided with at least one power line 110 and at least one VPX connector. At least one power board 200 is disposed on the VPX backplane 100. The power board 200 receives a power signal and generates a corresponding power supply signal based on the power signal and outputs it to the corresponding power line 110. A management board 300 is disposed on the VPX backplane 100 and can draw power from the power line 110. A communication board 400 is connected to the management board 300 and can draw power from the power line 110. The communication board 400 receives management control signals output by the management board 300 and generates corresponding communication signals based on the management control signals. This allows VPX communication and power supply functions to be implemented on the same VPX backplane 100, eliminating the need for an additional power board for separate power supply. This reduces the footprint of the expansion device and expands its application scenarios.

[0060] In some embodiments, the power board 200 can receive 110V-220V AC or DC as the input power signal, and rectify and step-down the input power signal to obtain the required power supply signal to be output to the power line 110, so that when the expansion device is used for VPX protocol communication, there is no need to set up an additional power board for power supply, which reduces the additional wiring harness setting and avoids problems such as system shutdown caused by power harness and communication harness failure in high-voltage energy storage direct-hanging systems.

[0061] In some embodiments, the power board 200 includes a power VPX connection interface. The power board 200 can be connected to the VPX connector on the VPX backplane 100 through the power VPX connection interface to realize signal transmission between the power board 200 and other functional modules on the VPX backplane 100. The VPX connector can also be used to realize power supply to other functional modules on the VPX backplane 100, thereby realizing the integration of power and VPX communication functions and reducing additional hardware costs.

[0062] In some embodiments, the management board 300 includes a high-speed communication VPX connection interface and a low-speed communication VPX connection interface. The management board 300 can be connected to the VPX connector on the VPX backplane 100 through the high-speed communication VPX connection interface and the low-speed communication VPX connection interface.

[0063] In this embodiment, by setting a high-speed communication VPX connection interface and a low-speed communication VPX connection interface on the management board 300 to connect the VPX connector on the VPX backplane 100, VPX communication can be achieved between the power board 200 and the management board 300 or between the power board 200, the management board 300 and the external functional modules, thereby realizing the integration of power and VPX communication functions.

[0064] In some embodiments, as shown in FIG2 , there may be multiple power boards 200 and multiple power lines 110. The multiple power boards 200 are configured to receive multiple power signals, convert the power signals into corresponding power supply signals, and output them to the corresponding power lines 110.

[0065] In this embodiment, multiple power boards 200 can be connected to multiple power lines 110 accordingly. By setting multiple power lines 110 and multiple VPX connectors on the VPX backplane 100, multiple power boards 200 convert multiple power signals into corresponding power supply signals and output them to the corresponding power lines 110, and a management board 300 is set to output management control signals after drawing power from the multiple power lines 110. In the event of a failure in any power line 110 or power board 200, the management board 300 will not be powered off.

[0066] In some embodiments, multiple communication boards 400 can also output management control signals after drawing power from multiple power lines 110. In the event of a failure in any power line 110 or power board 200, the communication board 400 will not be powered off.

[0067] In some embodiments, when multiple power boards 200 and multiple power lines 110 are provided on the VPX backplane 100, the power access port of the management board 300 or the communication board 400 can be provided with a power mutual exclusion device or a power mutual exclusion circuit, such as a diode, etc., and the multiple diodes correspond to the multiple power lines 110 respectively. The power mutual exclusion device or the power mutual exclusion circuit can prevent the multiple power inputs from affecting each other.

[0068] In some embodiments, as shown in Figure 2, there can be multiple management boards 300, and the communication boards 400 are respectively connected to the multiple management boards 300, and the multiple communication boards 400 are used to draw power from multiple power lines 110. In the event of a failure in any power line 110 or the power board 200, the management board 300 will not be powered off. The multiple management boards 300 provide management control signals to the communication board 400 through the corresponding VPX connector. In the event of a failure in any management board 300, the signal output of the communication board 400 will not be affected, that is, the control of the subsequent circuit will not be affected. For example, when the subsequent circuit is connected to the energy storage valve, the normal operation of the energy storage valve will not be affected in the event of a failure in any management board 300.

[0069] In some embodiments, as shown in FIG. 2 , there may be multiple communication boards 400 . The communication boards 400 draw power from the power line 110 , and generate communication signal outputs according to management control signals provided by the management board 300 .

[0070] In this embodiment, multiple communication boards 400 are connected to the management board 300, and the multiple communication boards 400 are used to draw power from multiple power lines 110. In the event of a failure in any power line 110 or the power board 200, the communication board 400 will not be powered off. Each communication board 400 converts the management control signal into a corresponding communication signal. In the event of a failure in any communication board 400, the output of the expansion device will not be affected. Therefore, in the event of a failure in any communication board 400, it can be repaired or replaced at any time without affecting the functions within the expansion device. There is no need to control the expansion device or the subsequent circuit connected to the expansion device to power off, thereby improving the stability of the expansion device.

[0071] In some embodiments, as shown in FIG2 , multiple power lines 110 are provided on the VPX backplane 100, multiple power boards 200 convert multiple power signals into corresponding power supply signals and output them to the corresponding power lines 110, and a management board 300 is provided to output management control signals after receiving power from the multiple power lines 110. Each communication board 400 is connected to multiple management boards 300, and multiple communication boards 400 are used to receive power from multiple power lines 110. In the event of a failure in any power line 110 or power board 200, the management board 300 will not be powered off. 00 provides management control signals to the communication board 400 through the corresponding VPX connector. Each communication board 400 receives the management control signals output by multiple management boards 300 and converts the management control signals into communication signals. Failure of any one of the management boards will not cause problems with the communication board input. Therefore, if any power board 200 or management board 300 fails, it can be repaired or replaced at any time without affecting the functions within the expansion device. There is no need to control the expansion device or the subsequent circuit connected to the expansion device to cut off power, which improves the stability of the expansion device.

[0072] In some embodiments, the VPX backplane 100 can be a PowerVPX board, which can integrate power lines and communication lines with the VPX protocol. VPX is a new generation of high-speed serial bus standard. The PowerVPX board refers to a printed circuit board that integrates both the VPX bus and power lines. The VPX bus can transmit communication signals of the VPX protocol, and can realize the integration of high power, low power and communication.

[0073] In some embodiments, as shown in Figure 3, the expansion device includes multiple groups of power modules 500, which are respectively connected to multiple communication boards 400. The multiple groups of power modules 500 draw power from multiple power lines 110. Each group of power modules 500 is used to receive corresponding communication signals and switch working states according to the communication signals.

[0074] In this embodiment, multiple groups of power modules 500 can drive multiple loads. Each group of power modules 500 can obtain a communication signal from a corresponding communication board and switch the working state based on the communication signal. Different loads can be driven to corresponding working states according to application requirements, and the driving process of the power module 500 can be adjusted based on the communication signal.

[0075] In some embodiments, as shown in Figure 4, at least a first power line 101 and a second power line 102 are provided on the VPX backplane 100; the multiple power boards 200 include at least a first power board 210 and a second power board 220 provided on the VPX backplane 100, the first power board 210 is used to receive a first power signal, and convert the first power signal into a first power supply signal and output it to the first power line 101; the second power board 220 is used to receive a second power signal, and convert the second power signal into a second power supply signal and output it to the second power line 102.

[0076] In this embodiment, the first power board 210 and the second power board 220 can provide the first power signal and the second power signal to the first power line 101 and the second power line 102 respectively, thereby forming a dual-redundant power supply system. Other functional boards on the VPX backplane 100 can be connected to the first power line 101 and the second power line 102 at the same time. The power input port of the functional board can be provided with a power competition circuit to avoid input conflict between the two input power supplies. When one of the power supplies fails, the normal operation of the VPX backplane 100 can be ensured, thereby improving the stability of the expansion device. In addition, the faulty power supply can be replaced online to ensure that the expansion device can operate online without interruption.

[0077] In some embodiments, as shown in Figure 4, multiple management boards 300 include a first management board 310 and a second management board 320 arranged on the VPX backplane 100, and multiple communication boards 400 are connected to the first management board 310 and the second management board 320; each group of power modules 500 is connected to a corresponding communication board 400.

[0078] In this embodiment, each communication board 400 is simultaneously connected to the first management board 310 and the second management board 320, and the first management board 310 and the second management board 320 perform the same function. When the first management board 310 fails, each communication board 400 can still receive the management control signal output by the second management board 320, and generate a communication signal based on the management control signal and send it to the power module 500. Similarly, when the second management board 320 fails, each communication board 400 can still receive the management control signal output by the first management board 310, and generate a communication signal based on the management control signal and send it to the power module 500, thereby ensuring that the power module 500 can always correctly execute the corresponding instructions. Damage to any power supply or management board 300 will not affect the function of the entire device, and the power supply or management board 300 can be replaced online.

[0079] In some embodiments, as shown in FIG. 4 , the first power board 210 is used to supply power to the first management board 310 , and the second power board 220 is used to supply power to the second management board 320 .

[0080] In this embodiment, the first power board 210 and the second power board 220 respectively supply power to the first management board 310 and the second management board 320, and can form two control circuits respectively. Each power board 200 and the corresponding management board 300 form a control circuit. When any power board 200 or management board 300 of the control circuit fails, it can be replaced online.

[0081] In some embodiments, the plurality of power boards 200 are connected to the plurality of management boards 300 in a one-to-one correspondence.

[0082] In this embodiment, each power board 200 can independently supply power to one of the management boards 300. Each power board 200 and the corresponding management board 300 form a control circuit. When any power board or management board of the control circuit fails, it can be replaced online.
