[0040] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions of this application are further elaborated in detail below with reference to the accompanying drawings and embodiments. The described embodiments should not be regarded as limiting this application. All other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0041] In the following description, reference is made to “some embodiments”, which describes a subset of all possible embodiments, but it will be understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.

[0042] The terms "first / second / third" involved are merely used to distinguish similar objects and do not represent a specific ordering of the objects. It is understandable that "first / second / third" can be interchanged with a specific order or sequence where permitted so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein.

[0043] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application pertains. The terms used herein are for the purpose of describing this application only and are not intended to limit this application.

[0044] In order to solve the technical problem that the test equipment in the related art is not accurate enough in testing the energy storage system, the embodiment of the present application provides a test equipment applied to the energy storage system, such as Figure 1As shown, the test device 10 includes a cabinet 100 having a receiving cavity, and a control device 200, an interface expansion device 300, a first test device 400, and a second test device 500 arranged in the cabinet 100; the first test device 400 is connected to the control device 200, the interface expansion device 300 is connected to the control device 200, and the second test device 500 is connected to the interface expansion device 300; wherein,

[0045] The second testing device 500 is used to simulate the energy storage submodule in the energy storage system and communicate with the interface expansion device 300;

[0046] The first testing device 400 is used to simulate an external system in the energy storage system and communicate with the control device 200 .

[0047] In an embodiment of the present application, the control device may be a master control device in an energy storage system, configured to control and protect the energy storage submodules within the energy storage system. The interface expansion device is an interface device connected to the energy storage submodules in the energy storage system, configured to implement real-time interaction with the energy storage submodules. The first and second test devices are both test fixtures within the test equipment, configured to perform various testing tasks on the energy storage system. These testing tasks may be static simulation tests. Exemplarily, these static simulation tests may include interface communication tests, device self-test tests, start / stop sequence control tests, and fault handling tests. Exemplarily, the energy storage system may be an energy storage valve system. The energy storage valve is a core component of a high-voltage direct-connect energy storage system and serves as the core functional module for battery charging and discharging. The expansion device is an energy storage valve control device, connected upstream to the DC control and protection system, monitoring system, and clock system to receive and process control commands. It is also connected downstream to the converter valve and serves as the core control unit for the converter valve, controlling, monitoring, and protecting the converter valve.

[0048] It is understandable that when performing the above-mentioned test tasks, the test equipment needs to simulate the actual operating environment of the energy storage system. For example, when testing the communication process of the control device, if the communication process of the control device is tested only by external test equipment, then even if the test result of the control device is qualified in the current test environment, because the current test environment does not match the actual operating environment of the energy storage system (that is, the current test environment does not have an external system of the energy storage system), when the control device with qualified test results is applied to the actual energy storage system, problems may still occur. Therefore, it is necessary to integrate the devices used in the energy storage system so that the test environment has good integration to simulate the actual operating environment of the energy storage system.

[0049] In the embodiment of the present application, the second testing device is provided with a plurality of interfaces for simulating energy storage submodules, through which the communication connection between the energy storage submodules in the energy storage system and the interface expansion device can be simulated.

[0050] In the embodiment of the present application, the first test device is provided with a plurality of interfaces for simulating different types of systems in the external system. The communication connection conditions between different types of external systems and the control device can be simulated through different types of interfaces.

[0051] In the embodiment of the present application, a first test device simulates the external system of the energy storage system, and a second test device simulates the energy storage submodule. Thus, according to the connection relationship between the various devices of the energy storage system, the control device, the interface expansion device, the first test device, and the second test device are connected together to form a test device that matches the actual operation of the energy storage system. In this way, the various devices used in the energy storage system can be integrated into the test device, making the test environment well-integrated, accurately simulating the actual operating environment of the energy storage system, and thus improving the accuracy of testing the energy storage system through the test device.

[0052] In some embodiments, as Figure 2 and Figure 3 As shown, the control device 200 includes a control backplane 201 and multiple first boards 202; the control backplane 201 includes multiple sockets 2011 for connecting the first boards 202; the first board 202 includes a pole control communication interface 2021 and an auxiliary communication interface 2022; the first test device 400 includes a first test backplane 401 and a second board 402; the first test backplane 401 includes multiple sockets 4011 for connecting the second board 402; the second board 402 includes an analog pole control interface 4021 and an analog auxiliary interface 4022; the analog pole control interface 4021 of the first test device 400 is connected to the pole control communication interface 2021 of the control device 200; the analog auxiliary interface 4022 of the first test device 400 is connected to the auxiliary communication interface 2022 of the control device 200.

[0053] It is understandable that in a normally operating energy storage system, the control device needs to communicate with the pole control system and the auxiliary system. In the embodiment of the present application, the communication process between the control device and the pole control system in the energy storage system can be simulated by connecting the simulated pole control interface of the first test device to the pole control communication interface of the control device; and the communication process between the control device and the auxiliary system in the energy storage system can be simulated by connecting the simulated auxiliary interface of the first test device to the auxiliary communication interface of the control device. In this way, the control device can be tested in a test environment that matches the actual operating environment of the energy storage system.

[0054] In the embodiment of the present application, the external system in the energy storage system may include a pole control system and an auxiliary system. The pole control system may be an AC / DC conversion control system, and the auxiliary system may include at least one of the following: a valve cooling unit, a heating and ventilation unit, a fire protection unit, and a measurement unit.

[0055] In the embodiment of the present application, the communication process between the pole control system and the control device can be simulated by connecting the analog pole control interface of the first test device to the pole control communication interface of the control device. The communication process between the auxiliary system and the control device can be simulated by connecting the analog auxiliary interface of the first test device to the auxiliary communication interface of the control device. This can accurately simulate the actual operating environment of the energy storage system, thereby improving the accuracy of testing the energy storage system through the test equipment.

[0056] In some embodiments, as Figure 2 and Figure 4 As shown, the interface expansion device 300 includes an interface expansion backplane 301 and a third board 302; the interface expansion backplane 301 includes multiple sockets 3011 for connecting the third board 302; the third board 302 includes at least one first communication interface 3021; the first board 202 of the control device 200 also includes an extended communication interface 2023; the first communication interface 3021 of the interface expansion device 300 is connected to the extended communication interface 2023 of the control device 200.

[0057] In this embodiment of the present application, the interface expansion device can be consistent with the expansion device of the energy storage system, wherein the expansion device of the energy storage system is used to aggregate data from the energy storage submodules in the energy storage system. In this embodiment of the present application, because the energy storage submodules in the energy storage system are simulated by the second test device, the interface expansion device in the test equipment is used to aggregate data from the second test device.

[0058] In some embodiments, an extended communication interface in the control device can be connected to at least two first communication interfaces in the interface expansion device. In other words, one extended communication interface in the control device can be connected to at least two first communication interfaces. This redundant connection improves the stability of communication between the interface expansion device and the control device.

[0059] In an embodiment of the present application, by connecting the extended communication interface of the control device to the first communication interface of the interface extension device, the communication process between the control device and the extension device in the energy storage system can be simulated, thereby accurately simulating the actual operating environment of the energy storage system, thereby improving the accuracy of testing the energy storage system through the test equipment.

[0060] In some embodiments, as Figure 4 and Figure 5As shown, the second test device 500 includes a second test backplane 501 and a fourth board 502; the second test backplane 501 includes a plurality of sockets 5011 for connecting the fourth board 502; the fourth board 502 includes at least one analog module interface 5021, and the analog module interface 5021 is used to simulate the energy storage sub-module; the third board 302 of the interface expansion device 300 also includes at least one second communication interface 3022; the at least one second communication interface 3022 of the interface expansion device 300 is respectively connected to the at least one analog module interface 5021 of the second test device 500.

[0061] It is understood that in a normally operating energy storage system, the expansion device needs to communicate with multiple energy storage submodules to aggregate their data. In this embodiment of the present application, the communication process between the expansion device and the energy storage submodules in the energy storage system can be simulated by connecting the simulation module interface of the second testing device to the second communication interface of the interface expansion device. This allows the control device to be tested in a test environment that matches the actual operating environment of the energy storage system.

[0062] In an embodiment of the present application, each of the at least one simulation module interface of the second test device is used to simulate at least one energy storage submodule (Sub Module Controller, SMC) in the energy storage system. The number of simulation module interfaces connected to the second communication interface of the interface expansion device is related to the number of energy storage submodules connected to the expansion device in the energy storage system. For example, if one simulation module interface is used to simulate one energy storage submodule, and the number of energy storage submodules connected to the expansion device in the energy storage system is a, then the second communication interface of the interface expansion device is communicatively connected to a simulation module interfaces of the second test device. In this way, by providing at least one simulation module interface in the second test device, the second communication interface of the interface expansion device can be flexibly communicatively connected to the simulation module interface of the second test device according to the actual situation of the energy storage submodule in the energy storage system, thereby not only being able to accurately simulate the real operating environment of the energy storage system, but also improving the test flexibility and test scalability of the test equipment.

[0063] In some embodiments, as Figure 1As shown, a debugging communication device 600 is also provided in the accommodating cavity; the debugging communication device 600 is connected to the debugging interface of the control device 200, the debugging interface of the first test device 400 and the debugging interface of the second test device 500; the debugging communication device 600 is connected to the debugging network port of the debugging industrial computer (not shown in the figure); wherein the debugging industrial computer is used to communicate with the control device 200, the first test device 400 and the second test device 500 through the debugging communication device 600, so as to deploy and / or update the software systems in the control device 200, the first test device 400 and the second test device 500.

[0064] Here, the debugging communication device can be a local area network switch used to establish a debugging local area network, thereby enabling the debugging industrial computer to deploy and / or update software for the control device, the first test device, and the second test device in the test equipment through the debugging local area network. In this way, by providing the debugging communication device, functions such as one-click deployment, one-click update, and real-time interaction can be achieved for the control device, the first test device, and the second test device.

[0065] In the embodiments of the present application, a debugging communication device is provided in the debugging device, and the control device, the first test device, and the second test device are respectively connected to the debugging industrial computer via the debugging communication device. This enables software deployment and / or software updates for the control device, the first test device, and the second test device, thereby improving the convenience of deploying and / or updating software for each device in the debugging device.

[0066] In some embodiments, as Figure 1 As shown, a recording device 700 is also provided in the accommodating cavity; the recording device 700 includes a recording backboard and a fifth board card (not shown in the figure); the recording backboard includes a plurality of sockets for connecting the fifth board card; the fifth board card includes a debugging interface, a third communication interface, and a fourth communication interface of the recording device; the debugging interface of the recording device is connected to the debugging communication device; the third communication interface of the recording device is connected to the recording communication interface of the control device; the fourth communication interface of the recording device is connected to the fifth communication interface connected to the interface extension device; wherein, the recording device is used to obtain real-time recording information of the control device and the interface extension device; the real-time recording information is used to determine whether the control device and the interface extension device have failed.

[0067] Here, the first board of the control device also includes the aforementioned wave recording communication interface, and the third board of the interface expansion device also includes a fifth communication interface. The control device can be connected to the fourth communication interface of the wave recording device via the wave recording communication interface, and the interface expansion device can be connected to the fourth communication interface of the wave recording device via the fifth communication interface, thereby enabling the wave recording device to collect real-time wave recording information from the control device and the interface expansion device. The fourth communication interface of the wave recording device can be a wave recording port.

[0068] In an embodiment of the present application, the recording device is a monitoring device in the test equipment, which is used to collect and record test data (i.e., real-time recording information). By analyzing the real-time recording information, it can be determined whether the control device and the interface expansion device have failed.

[0069] In some embodiments, the recording device can be communicatively connected to a recording analysis device for analyzing real-time recording information. The recording analysis device can analyze the real-time recording information to determine whether the control device and the interface expansion device have failed.

[0070] In an embodiment of the present application, the debugging interface of the recording device can be connected to the debugging host computer through the debugging communication device, so that the debugging host computer can deploy and / or update the software system in the recording device through the debugging communication device.

[0071] In an embodiment of the present application, by providing a recording device in the debugging equipment, it is possible to collect real-time recording information of the control device and the interface expansion device during the test process, thereby determining whether the control device and the interface expansion device have faults through the real-time recording information, thereby improving the accuracy of testing the energy storage system through the test equipment.

[0072] In some embodiments, as Figure 1 As shown, at least two monitoring and communication devices 800 are also provided in the accommodating cavity; at least two monitoring and communication devices 800 are respectively connected to the control device 200; at least two monitoring and communication devices 800 are respectively connected to at least two monitoring devices (not shown in the figure); wherein, at least two monitoring devices are used to send control instructions to the control device 200 through at least two monitoring and communication devices 800 to control the control device 200.

[0073] Here, the monitoring communication device may be a local area network switch, which is used to construct a monitoring local area network, so that the monitoring device controls the control device through the monitoring local area network.

[0074] In the embodiment of the present application, there are at least two monitoring communication devices. That is, within the test environment corresponding to the test equipment, there are at least two monitoring local area networks, and each monitoring local area network is connected to a different monitoring device. In this way, each monitoring device can issue control instructions to the control device through its corresponding monitoring local area network. This redundant configuration of the monitoring communication devices makes the test environment corresponding to the test equipment more stable and reduces the possibility of the monitoring device being unable to control the control device due to a monitoring device failure.

[0075] In some embodiments, the monitoring local area networks corresponding to the at least two monitoring communication devices are in different network segments. For example, the monitoring local area networks corresponding to the at least two monitoring communication devices may include a monitoring local area network in network segment A and a monitoring local area network in network segment B. In this way, establishing monitoring local area networks in different network segments can improve the stability of the test environment corresponding to the test equipment.

[0076] In some embodiments, when the monitoring device sends a control instruction to the control device through the monitoring communication device, the monitoring device can carry parameter information in the control instruction, so that the control device can be configured according to the parameter information to complete the test task.

[0077] In some embodiments, as Figure 2 、 Figure 3 and Figure 6 As shown, the number of the above-mentioned control devices 200 is at least two; the first board 202 of each control device 200 also includes a safety communication interface 2024 and a control communication interface 2025; the second board 402 of the first test device 400 also includes a simulated safety communication interface 4023; each two control devices 200 in the at least two control devices 200 are connected to each other through the control communication interface 2024; the first test device 400 is connected to the safety communication interface 2023 of each control device through the simulated safety communication interface 4023.

[0078] It is understandable that energy storage systems employ redundant control devices to improve system stability. Therefore, to realistically simulate an energy storage system, the test equipment can also employ redundant control devices based on the same setup used in the energy storage system.

[0079] Here, the simulated safety communication interface is a communication interface in the test fixture used to simulate the 3-out-of-2 function in the energy storage system. Thus, by providing a simulated safety communication interface in the first test device and connecting the first test device to the safety communication interface of each control device via the simulated safety communication interface, the 3-out-of-2 function in the energy storage system can be simulated.

[0080] In an embodiment of the present application, each control device is provided with a control communication interface, so that each two control devices in at least two control devices can be connected to each other through the control communication interface, thereby simulating the hot standby redundant structure of the energy storage system, and thus making the test equipment more suitable for the actual use scenario of the energy storage system.

[0081] In some embodiments, if the test equipment includes at least two control devices, the number of recording devices in the test equipment is also at least two, and the at least two recording devices correspond one-to-one to the at least two control devices. In this embodiment of the present application, the at least two recording devices are connected to the recording communication interfaces of the at least two control devices via their own third communication interfaces in a one-to-one correspondence.

[0082] Illustratively, the test equipment includes a control device A, a control device B, a wave recording device A, and a wave recording device B. The wave recording communication interface of the control device A is connected to the third communication interface of the wave recording device A, and the wave recording communication interface of the control device B is connected to the third communication interface of the wave recording device B. In this way, real-time wave recording information of the control device A can be collected by the wave recording device A, and real-time wave recording information of the control device B can be collected by the wave recording device B.

[0083] In other embodiments, the test equipment may also collect real-time recording information of at least two control devices through a recording device, that is, the third communication interface of the recording device is connected to the recording communication interfaces of the at least two control devices respectively.

[0084] In an embodiment of the present application, a simulated safety communication interface is provided in a first test device, and the first test device is connected to the safety communication interface of each control device through the simulated safety communication interface, thereby simulating the three-out-of-two function in the energy storage system. Furthermore, a control communication interface is provided in the control device, and each of the at least two control devices can be connected to each other through the control communication interface, thereby simulating the hot standby redundant structure of the energy storage system. In this way, the three-out-of-two function in the energy storage system is simulated through the simulated safety communication interface, and the hot standby redundant structure of the energy storage system is simulated through the control communication interface, so that the test equipment is more in line with the actual use scenario of the energy storage system, thereby improving the accuracy of testing the energy storage system through the test equipment.

[0085] In some embodiments, as Figure 7 As shown, the number of interface expansion devices 300 is at least two; the number of first communication interfaces of each interface expansion device 300 is at least two; each interface expansion device 300 is connected to the extended communication interface of each control device 200 through at least two first communication interfaces; each interface expansion device 300 is connected to at least one analog module interface of the second test device through at least one second communication interface.

[0086] It is understandable that the function of the expansion device in the energy storage system is to aggregate data from multiple energy storage sub-modules. Because the expansion device has limited interfaces for connecting to the energy storage sub-modules, and the number of energy storage sub-modules in the energy storage system is relatively large, it is necessary to connect the multiple energy storage sub-modules separately through at least two expansion devices. Therefore, in order to improve the matching degree between the test equipment and the actual application of the energy storage system, at least two interface expansion devices are provided in the test equipment. In accordance with the communication connection mode of the at least two expansion devices, the control device, and the multiple energy storage sub-modules in the energy storage system, each interface expansion device is connected to the extended communication interface of each control device through at least two first communication interfaces, and each interface expansion device is connected to at least one simulation module interface of the second test device through at least one second communication interface.

[0087] In some embodiments, if the test equipment includes at least two interface expansion devices, the number of wave recording devices in the test equipment is also at least two, and the number of wave recording devices is equal to the number of the at least two interface expansion devices. In this embodiment of the present application, the at least two wave recording devices are connected to the fifth communication interfaces of the at least two interface expansion devices via their third communication interfaces.

[0088] Illustratively, the testing equipment includes an interface expansion device A, an interface expansion device B, a wave recording device A, and a wave recording device B. The fifth communication interface of the interface expansion device A is connected to the third communication interface of the wave recording device A, and the fifth communication interface of the interface expansion device B is connected to the third communication interface of the wave recording device B. In this way, real-time wave recording information of the interface expansion device A can be collected by the wave recording device A, and real-time wave recording information of the interface expansion device B can be collected by the wave recording device B.

[0089] Alternatively, the third communication interface of recording device A is connected to the fifth communication interface of interface expansion device A and the fifth communication interface of interface expansion device B. In this way, real-time recording information of interface expansion device A and interface expansion device B can be collected by recording device A, and real-time recording information of interface expansion device A and interface expansion device B can also be collected by recording device B.

[0090] In the embodiments of the present application, at least two expansion devices are provided in the test equipment, and the at least two expansion devices are connected to the control device and the at least two expansion devices to the second test device according to the communication method of each device in the energy storage system. This makes the test equipment more suitable for the actual use scenario of the energy storage system, thereby improving the accuracy of the energy storage system tested by the test equipment.

[0091] In some embodiments, as Figure 8As shown, a first power supply device 900 and a second power supply device 1000 are provided in the accommodating cavity; the first power supply device 900 is respectively connected to the power interface of the control device, the power interface of the interface expansion device, the power interface of the first test device, the power interface of the second test device and the power interface of the recording device; the first power supply device 900 is respectively connected to the backup power interface of the control device and the backup power interface of the interface expansion device; wherein, the first power supply device 900 is used to supply power to the control device, the interface expansion device, the first test device, the second test device and the recording device; the second power supply device 1000 is used to supply power to the backup power supply of the control device and the backup power supply of the interface expansion device.

[0092] Exemplarily, the first power supply device and the second power supply device may be power distribution units (PDUs).

[0093] In the embodiment of the present application, the first power supply device can be used to provide real-time power to each device of the test equipment, and the second power supply device can be used to provide power to the backup power supply of the control device and the backup power supply of the interface expansion device. In this way, by using different power supply devices to provide real-time power to each device in the test equipment, and to provide backup power to the control device and the interface expansion device of the test equipment, the stability of the test equipment can be improved, because the core devices of the test equipment (i.e., the control device and the interface expansion device) have a backup power supply, and the power is supplied by a power supply device different from the real-time power supply device, so the situation where the core device cannot work due to power outage can be reduced.
