[0093] In a flexible DC energy storage system, the multi-level cascading technology can be utilized to distributively integrate energy storage units in half-bridge modules to achieve high-voltage direct connection energy storage. It can simultaneously achieve AC-DC power conversion and energy storage, and has advantages such as high modularity, good harmonic characteristics, and low equivalent switching frequency. In related technologies, a high-voltage direct connection energy storage system generally consists of multiple cascaded energy storage sub-module controllers, and the sub-module controllers are used to control and protect individual energy storage sub-module controllers. Therefore, the control software and hardware of the energy storage sub-module controller need to have high security and reliability. Thus, it is very necessary to conduct rigorous tests on it before putting it into use, and the main test contents include: the software control function, software monitoring function, hardware path, and reliability of the energy storage sub-module controller. However, based on the above test contents, in related technologies, a complete energy storage system simulation model needs to be built to test the energy storage sub-module controller, and the energy storage sub-module controller cannot be tested alone. In addition, the test methods in related technologies generally cannot test software and hardware simultaneously. Based on the above problems, this application proposes a test method for an energy storage system, which can achieve automatic testing of the energy storage sub-module controller and can simultaneously test software and hardware. The following embodiments will specifically illustrate this test method.

[0094] The test method for an energy storage system provided by an embodiment of this application can be applied to an application environment as Figure 1 shown. Among them, the test device 102 communicates with the energy storage sub-module controller 104 through a network. Multiple model boards are set on the test device 102, and each model board is used to simulate the corresponding interface to communicate with the hardware interface on the energy storage sub-module controller 104 to complete the test; the energy storage sub-module controller 104 is any energy storage sub-module controller in the energy storage system, and various types of interfaces are set on it, such as, transistor switch interfaces, busbar switch interfaces, and bypass switch interfaces. The test device 102 can be but is not limited to various personal computers, laptop computers, smart phones, tablet computers, Internet of Things devices, etc.

[0097] Among them, different types of hardware interfaces are set on the energy storage sub-module controller to be tested, such as, Insulate-Gate Bipolar Transistor (IGBT) drive optical interfaces, busbar drive optical interfaces, and bypass drive optical interfaces, etc.

[0098] In the embodiments of the present application, when it is necessary to test the energy storage sub-module controller to be tested, the energy storage sub-module controller to be tested can generate a driving signal and send the driving signal to the test device, so that the test device can test the hardware path or the software and hardware of the energy storage sub-module controller based on the driving signal; optionally, the energy storage sub-module controller to be tested can also generate multiple driving signals and send the multiple driving signals to the test device, so that the test device can test the hardware path or the software and hardware of the energy storage sub-module controller based on the multiple driving signals.

[0099] S202. Send a feedback signal to the energy storage sub-module controller to be tested according to the driving signal.

[0100] Among them, the feedback signal is used to represent the feedback state when the test device receives the driving signal, including normal feedback and abnormal feedback.

[0101] In the embodiments of the present application, the test device can pre-collect the test logics of different types of interfaces (including the test logics in normal states and abnormal states) according to different model board manuals, and edit program codes according to the test logics of different types of interfaces to generate different model boards, that is, the program codes of different types of interfaces; the program codes can automatically give feedback based on the driving signal to generate a feedback signal, so as to simulate the corresponding functions of different types of interfaces or simulate the corresponding functions of different model boards. When the test device generates a feedback signal based on the driving signal, the feedback signal can be directly returned to the energy storage sub-module controller to be tested.

[0102] S203. Receive the first driving result reported by the energy storage sub-module controller to be tested based on the feedback signal.

[0103] Among them, the first driving result includes the information of the feedback signal counted by the sub-module to be tested. For example, the information of the feedback signal can include the number of received feedback signals, the number of feedback signals indicating normal states, and the number of feedback signals indicating abnormal states.

[0104] In the embodiments of the present application, when the energy storage sub-module controller to be tested receives the feedback signal, it can analyze the feedback signal to determine the feedback state it represents, that is, determine whether the above information interaction process is normal through the feedback state, and obtain the first driving result. The information interaction process includes several interaction processes in which the energy storage sub-module controller to be tested sends a driving signal, the test device receives the driving signal, and the test device returns a feedback signal to the energy storage sub-module controller to be tested.

That is, the above method realizes simultaneous testing of the software and hardware on the energy storage sub-module controller under test. Compared with the traditional test technology that completes testing by transmitting data between the physical interfaces of devices and can only achieve the effect of hardware testing, the above test method has a wider application range and lower test cost.

[0108] In one embodiment, as Figure 3 shown, when the test device executes S202 and S203 above, it can specifically execute the steps:

For example, the target interface can be any one of the transistor switch interface, the busbar switch interface, and the bypass switch interface. The test device is provided with the same type of interface corresponding to the interface on the energy storage sub-module controller to be tested. For example, if the energy storage sub-module controller to be tested is provided with a transistor switch interface, a busbar switch interface, and a bypass switch interface, correspondingly, the test device is provided with a transistor switch interface, a busbar switch interface, and a bypass switch interface.

[0111] In the embodiment of the present application, when it is necessary to test the energy storage sub-module controller to be tested, the energy storage sub-module controller to be tested can generate a drive signal and send the drive signal to the test device through the target interface. The interface corresponding to the target interface on the test device can receive the drive signal and can test the hardware path or the software and hardware of the energy storage sub-module controller based on the drive signal; optionally, the energy storage sub-module controller to be tested can also generate multiple drive signals. When the multiple drive signals are drive signals of the same type of interface, the energy storage sub-module controller to be tested can send the multiple drive signals to the test device through the target interface. The interface corresponding to the target interface on the test device can receive the multiple drive signals and can test the hardware path or the software and hardware of the energy storage sub-module controller based on the multiple drive signals; optionally, when the multiple drive signals are drive signals of different types of interfaces, and the multiple drive signals are sent to the test device through different interfaces, the interfaces corresponding to the different interfaces on the test device can receive the multiple drive signals and can test the hardware path or the software and hardware of the energy storage sub-module controller based on the multiple drive signals.

[0112] S206, send a feedback signal to the target interface of the energy storage sub-module controller to be tested according to the drive signal.

[0113] In the embodiments of the present application, when the test device generates a feedback signal based on a drive signal, the feedback signal can be directly sent to the energy storage sub-module controller under test through the interface corresponding to the target interface on it, and the energy storage sub-module controller under test can receive the feedback signal sent by the test device through the target interface. Optionally, when the test device generates multiple feedback signals based on multiple drive signals, and these multiple drive signals are drive signals corresponding to the same type of interface, the test device can directly send the multiple feedback signals to the energy storage sub-module controller under test through the interface corresponding to the target interface on it, and the energy storage sub-module controller under test can receive the multiple feedback signals sent by the test device through the target interface; optionally, when the test device generates multiple feedback signals based on multiple drive signals, and these multiple drive signals are drive signals corresponding to different types of interfaces, the test device can directly send the multiple feedback signals to the energy storage sub-module controller under test through the interfaces corresponding to the respective target interfaces on it, and the energy storage sub-module controller under test can receive the feedback signals sent by the test device through the respective target interfaces.

Optionally, when the test device receives multiple driving signals and generates multiple feedback signals, it can perform statistical analysis on the feedback states of the feedback signals to obtain the second driving result; correspondingly, when the to-be-tested energy storage sub-module controller receives multiple feedback signals, it can perform statistical analysis on the feedback states of the multiple feedback signals to obtain the first driving result.

[0126] Among them, the preset configuration information can be collected from the manual information of the model board, which contains the test logics of various model boards or interfaces and the corresponding test parameters.

[0127] In the embodiments of the present application, the test device may pre-acquire preset configuration information and configure various model boards or various interfaces thereon according to the preset configuration information. During the configuration process, the test device may first perform logical configuration on each model board or interface according to the test logic of each model board or interface in the preset configuration information, and may further configure each model board or interface according to the test requirements by setting corresponding test parameters. When the test device receives a drive signal through the corresponding interface of the target interface, it may determine the drive state indicated by the drive signal according to the preset configuration information to determine the test requirements for the energy storage sub-module controller to be tested; and generate a feedback signal according to the drive signal according to the test logic of the corresponding target interface in the preset configuration information, and compare the feedback state of the feedback signal with the drive state of the drive signal to determine the second drive result. When it is determined through comparison that the feedback state represented by the feedback signal is consistent with the drive state indicated by the drive signal, it indicates that the test device has made a normal feedback according to the drive signal, that is, the target interface of the energy storage sub-module controller to be tested has sent a signal normally, so it is determined that the second drive result indicates that the target interface is in a normal state. When it is determined through comparison that the feedback state represented by the feedback signal is inconsistent with the drive state indicated by the drive signal, it indicates that the test device has made an abnormal feedback according to the drive signal, that is, the target interface of the energy storage sub-module controller to be tested has an abnormality, so it is determined that the second drive result indicates that the target interface is in an abnormal state.

[0128] In the method described in the embodiments of the present application, the test device can implement the path function test of the corresponding interface on the energy storage sub-module controller by analyzing the drive state of the received drive signal and the feedback state of the feedback signal. This method only needs to configure the interface corresponding to each interface on the test device, and the method is simple and easy to implement.

[0129] In one embodiment, when the test device determines the test result according to the first drive result and the second drive result, it specifically performs: if the first drive result and the second drive result are consistent, the test result indicates that the energy storage sub-module controller to be tested passes the test; if the first drive result and the second drive result are consistent, the test result indicates that the energy storage sub-module controller to be tested fails the test.

[0130] In the embodiments of the present application, if the first drive result and the second drive result are consistent, it indicates that the analysis results of the test device and the energy storage sub-module controller to be tested for the feedback signal are consistent. At this time, it can be determined that the energy storage sub-module controller to be tested passes the test; if the first drive result and the second drive result are inconsistent, it indicates that the analysis results of the test device and the energy storage sub-module controller to be tested for the feedback signal are inconsistent. At this time, it can be determined that the energy storage sub-module controller to be tested fails the test.

[0131] The method described in the embodiments of the present application can, to a certain extent, accurately test the to-be-tested energy storage sub-module controller by analyzing and comparing the test data of the to-be-tested energy storage sub-module controller and the test device.

[0132] In one embodiment, the test device also has a test statistical function, that is, it provides another implementation manner for determining the second driving result according to the feedback signal. This implementation manner includes: when receiving multiple feedback signals sent by the to-be-tested energy storage sub-module controller through the target interface, comparing whether the states represented by the feedback signals are consistent with the driving states indicated by the driving signals to determine the second driving result; wherein, the second driving result includes at least one of the number of feedback signals, the number of feedback signals representing the normal feedback state, and the number of feedback signals representing the abnormal feedback state.

[0133] In the embodiments of the present application, the to-be-tested energy storage sub-module controller can generate multiple driving signals and send the multiple driving signals to the test device through the same target interface; when the test device receives the multiple driving signals, it can generate corresponding feedback signals according to the driving signals, and further analyze the feedback states represented by the feedback signals, and analyze the driving states indicated by the driving signals according to the preset configuration information, and then determine whether the feedback states represented by the feedback signals are consistent with the driving states indicated by the corresponding driving signals, and count at least one of the number of generated feedback signals, the number of feedback signals representing the normal feedback state, and the number of feedback signals representing the abnormal feedback state to obtain the second driving result. It should be noted that the test device can also count the multiple feedback signals generated by the multiple driving signals received by different types of interfaces to complete the test.

[0134] The test method described in the embodiments of the present application can implement the test statistical function, that is, it can perform statistical analysis on the feedback states of multiple feedback signals, so as to determine the various interface function tests of the to-be-tested energy storage sub-module controller according to the statistical results.

[0135] In one embodiment, a method for sending feedback signals is also provided, that is, as Figure 6 shown, the above S205 "sending a feedback signal to the target interface of the to-be-tested energy storage sub-module controller according to the driving signal" includes:

[0137] Among them, the model board is the driver board for different types of devices.

The test device can simulate the state feedback of multiple different device driver boards through FPGA software, so as to simulate the way different model boards generate feedback signals according to the drive signal. For example, different model boards can include IGBT driver boards, bypass switch driver boards, bus switch driver boards, etc.

[0138] In the embodiment of the present application, when the test device receives a drive signal through the target interface corresponding interface, it can directly drive the model board corresponding to the target interface to generate a feedback signal. Optionally, different types of drive modules corresponding to the model boards can be preset on the test device. When the test device receives a drive signal, it can determine the model board corresponding to the drive signal, and can call the drive module corresponding to the model board to execute the corresponding interface test code, so that the drive module can determine the corresponding feedback signal according to the drive signal, that is, drive the model board corresponding to the target interface to generate a feedback signal according to the drive signal.

[0139] The test method described in the embodiment of the present application can simulate different feedback states of IGBT, bypass switch, and bus switch through a physical board, and then verify the performance of the to-be-tested energy storage sub-module controller under different feedback states, and can achieve rapid testing of the to-be-tested energy storage sub-module controller. In addition, the test device uses the same hardware board as the to-be-tested energy storage sub-module controller, which has high usability, and can also implement the testing of software and hardware.

[0140] In one embodiment, before the test device tests the to-be-tested energy storage sub-module controller, it can also execute the steps of: sending a test instruction to the to-be-tested energy storage sub-module controller; the test instruction is used to determine the target interface and generate a drive signal corresponding to the target interface.

[0141] Among them, the test instruction includes an IGBT drive instruction, a bypass switch drive instruction, a bus switch instruction, etc.

[0142] In the embodiment of the present application, the test device can also send various types of test instructions to the to-be-tested energy storage sub-module controller, that is, monitor various types of test instructions. Specifically, the test device can send a test instruction to the to-be-tested energy storage sub-module controller. After the to-be-tested energy storage sub-module controller receives the test instruction, it can parse the test instruction to determine the target interface to be tested, and generate a drive signal corresponding to the target interface, and send the drive signal to the test device through the target interface. After the test device receives the drive signal, it can drive the model board corresponding to the target interface to generate a feedback signal, and later can determine the correctness of the test instruction by counting the feedback state of the feedback signal.

[0143] The test method described in the embodiments of the present application can monitor IGBT drive instructions, bypass switch drive instructions, busbar switch instructions, etc., and has a function of counting the correctness and number of instructions, realizing the software test of the energy storage sub-module controller to be tested.

[0144] S502. Send a feedback signal to the target interface of the energy storage sub-module controller to be tested.

[0145] In the embodiments of the present application, when the test device generates a feedback signal based on a drive signal, the feedback signal can be directly sent to the energy storage sub-module controller to be tested through the interface corresponding to the target interface on it, and the energy storage sub-module controller to be tested can receive the feedback signal sent by the test device through the target interface. Optionally, when the test device generates multiple feedback signals based on multiple drive signals, and these multiple drive signals are drive signals corresponding to the same type of interface, the test device can directly send the multiple feedback signals to the energy storage sub-module controller to be tested through the interface corresponding to the target interface on it, and the energy storage sub-module controller to be tested can receive the multiple feedback signals sent by the test device through the target interface; optionally, when the test device generates multiple feedback signals based on multiple drive signals, and these multiple drive signals are drive signals corresponding to different types of interfaces, the test device can directly send the multiple feedback signals to the energy storage sub-module controller to be tested through the interfaces corresponding to the respective target interfaces on it, and the energy storage sub-module controller to be tested can receive the feedback signals sent by the test device through the respective target interfaces.

[0146] The test method described in the embodiments of the present application enables the test device to simulate the state feedback of different device model boards, and then realizes the rapid test of the energy storage sub-module controller to be tested by verifying the performance of the energy storage sub-module controller to be tested under different feedback states.
