In the flexible direct current energy storage valve control device, for example, the sub-module control board (SMC) is an important component and one of the core components of the photoelectric triggering and online monitoring system of high-voltage power devices. It is located on the high-voltage side of the device and is a bridge connecting the valve control system (VBC) and the battery management system (BMC). Therefore, it is very important to ensure the trouble-free and reliable operation of the sub-module control board.

[0003] Accelerated life test is an important method to study the reliability of energy storage valve control device. Accelerated life test increases test stress and accelerates the failure process of the product under test without changing the failure mechanism. It can obtain the life information of the product under test in a short time, which is conducive to reliability assessment of the product under test.

[0004] However, in the reliability assessment of the accelerated life test of the energy storage valve control device, it is difficult to accurately assess the reliability of the energy storage valve control device due to the large number of external interfaces of the energy storage valve control device and the large number of accelerated life test samples.

[0076] With the development of flexible direct current transmission technology, the application of electronic devices in power systems is becoming more and more extensive. In the flexible direct current energy storage valve control device, for example, the submodule central control board, as an important component and one of the core components of the photoelectric triggering and online monitoring system of high-voltage power devices, is located on the high-voltage side of the device and is a bridge connecting the valve control system and the battery management system. Therefore, it is very important to ensure the trouble-free and reliable operation of the submodule central control board.

[0077] Accelerated life test is an important method to study the reliability of energy storage valve control device. Accelerated life test increases test stress and accelerates the failure process of the product under test without changing the failure mechanism. It can obtain the life information of the product under test in a short time, which is conducive to reliability assessment of the product under test.

[0078] However, in the energy storage valve control device, since the energy storage valve control device has many external interfaces and the number of accelerated life test samples is generally large, it is not easy and uneconomical to use physical objects such as VBC, BMC and IGBT (Insulated Gate Bipolar Transistor) to build a test environment. Therefore, the current common practice is usually to test the samples to be tested through an aging test device with a trigger function. However, the above test scheme requires the connection of a physical thyristor, which only has a trigger function interface for the thyristor, and does not have other interface functions such as the test bypass switch and the confluence switch, and thus cannot obtain comprehensive and accurate test data to accurately evaluate the energy storage valve control device. In addition, it does not support the evaluation of the function and performance degradation of the samples to be tested during the aging test.

[0079] Based on the above considerations, in order to solve the problem that the aging test process of the current energy storage valve control device cannot be accurately evaluated, a test tool for energy storage valve control device (hereinafter referred to as the tool) is designed. A plurality of functional simulation transceiver interfaces are arranged on the hardware module of the tool. The functional simulation transceiver interface is correspondingly connected to the functional interface of the energy storage valve control device to be tested, and is used to simulate the behavior of the external interface of the energy storage valve control device to be tested, and receive and transmit the test status data, alarm data and degradation data fed back by the energy storage valve control device to be tested during the accelerated life test process. In the above scheme, the functional simulation transceiver interface can simulate the behavior of the external interface of the energy storage valve control device to be tested, realize the control and feedback information interaction with the energy storage valve control device to be tested, and then can simulate a variety of test conditions, and obtain the test status data, alarm data and degradation data of each test item fed back by the energy storage valve control device to be tested in a variety of accelerated life test processes, and can support the accurate accelerated life test results of the energy storage valve control device to be tested based on the test status data, alarm data and degradation data, and realize accurate reliability evaluation.

[0080] The energy storage valve control device test tooling provided in the present application includes, but is not limited to, an accelerated life test tooling suitable for a central control panel of a directly mounted energy storage valve submodule.

[0081] like Figure 1 As shown, the embodiment of the present application provides a test fixture for an energy storage valve control device, including: a hardware module 200, the hardware module 200 is provided with a plurality of functional simulation transceiver interfaces 220;

[0082] The functional simulation transceiver interface 220 is correspondingly connected to the functional interface of the energy storage valve control device to be tested, and is used to simulate the behavior of the external interface of the energy storage valve control device to be tested, and receive and transmit the test status data, alarm data and degradation data fed back by the energy storage valve control device to be tested during the accelerated life test process.

[0083] The number of hardware modules 200 can be one or more. In this embodiment, the number of hardware modules 200 can be more than one. A storage valve control device test fixture can be connected to multiple samples to be tested, which is suitable for the situation where the number of samples to be tested in the accelerated life test is multiple. The energy storage valve control device refers to a device used to control the energy storage valve in a photovoltaic power station or a flexible direct current converter station, which is a type of energy storage valve product. For example, the sub-module central control board (hereinafter referred to as the SMC board) can be regarded as an energy storage valve control device. The functional simulation transceiver interface refers to an interface simulated in order to test the communication protocol between various devices, which can be designed and implemented according to the test environment and test requirement data. The functional simulation transceiver interface generally consists of two parts: a transmitter and a receiver. The transmitter is responsible for generating and sending data messages, and encapsulating and encoding them according to the specified protocol; the receiver is responsible for receiving data messages, and parsing and decoding them according to the specified protocol. In this embodiment, the functional simulation transceiver interface can be designed according to the functional interface of the energy storage valve control device to be tested, and is used to connect with the functional interface of the energy storage valve control device to be tested in a one-to-one correspondence, simulate the behavior of the external interface of the energy storage valve control device to be tested, and receive and send data. The test status data can also be called aging test status data, which is various status parameter data collected when the energy storage valve control device to be tested is subjected to an aging test. These data include data from multiple aspects such as electrical parameters, communication alarm parameters, and board self-test status, which are used to evaluate the reliability and life of the energy storage valve control device to be tested. Degradation data is a product status parameter that gradually changes with time or the increase in the number of uses. By analyzing the degradation data of the product, information such as the failure rate curve, reliability curve, and failure rate curve of the product can be obtained, providing a basis for product design and improvement.

[0084] During the specific test process, the functional simulation transceiver interface 220 is connected one-to-one with the functional interface of the energy storage valve control device to be tested. When the tooling performs an aging test on the energy storage valve control device to be tested under preset aging test conditions, the functional simulation transceiver interface 220 can receive the test status data, alarm data and degradation data fed back by the energy storage valve control device to be tested during the accelerated life test process, and send the received data to the external control device, so that the external control device can realize the aging test evaluation of the energy storage valve control device to be tested based on the test status data, alarm data and degradation data.

[0085] Taking the energy storage valve control device to be tested as the SMC board to be tested as an example, the functional analog transceiver interface set by the tooling hardware module 200 may include a VBC analog transceiver interface, a BMC analog transceiver interface, a bypass switch analog transceiver interface, a confluence switch analog transceiver interface, an IGBT analog transceiver interface and an SMC board power interface, etc. Among them, the bypass switch analog transceiver interface and the confluence switch analog transceiver interface are both implemented by the control circuit of the optical module (modulatable light emission mode). Specifically, it can be by sending a feedback signal such as a fixed-cycle optical signal to indicate that the switch is in an open state (open position), and by sending a constant optical signal to indicate that the switch is in a closed state (closed position). If no optical signal is sent, it indicates that the communication is abnormal. The IGBT analog transceiver interface can also be implemented by an optical module, but it is different from the bypass switch analog transceiver interface and the confluence switch analog transceiver interface. Instead, it simulates the signal of the actual IGBT driver board according to certain rules, and the feedback signal is a non-optical signal of different lengths.

[0086] Specifically, according to the specific engineering design, a SMC board to be tested is connected, and the tooling has at least the following interfaces:

[0087] VBC simulated transceiver interface: The tooling is equipped with at least one pair of optical fiber transceiver communication interfaces to simulate VBC sending FT3 communication protocol messages.

[0088] IGBT analog transceiver interface: The tooling shall have at least 2 pairs of optical fiber transceiver communication interfaces.

[0089] Bypass switch analog transceiver interface: The tooling shall have at least one pair of optical fiber transceiver communication interfaces.

[0090] BMC simulated transceiver interface: The tooling has at least one pair of optical fiber transceiver communication interfaces to simulate BMC sending FT3 communication protocol messages.

[0091] Convergence switch analog transceiver interface: The tooling shall have at least one pair of optical fiber transceiver communication interfaces.

[0092] The test fixture with the above-mentioned functional simulation transceiver interface can receive the test status data, alarm data and degradation data fed back by the SMC board during the accelerated life test when the SMC board under test is subjected to an aging test, and send the above-mentioned received data to an external control device, so that the external control device can realize an aging test evaluation of the energy storage valve control device under test based on the test status data, alarm data and degradation data.

[0093] In the technical solution of the embodiment of the present application, based on the current situation that the energy storage valve control device has a large number of external interfaces and the existing test tooling equipment is difficult to test the functions and performances of the external interfaces of the energy storage valve control device, an accelerated life test tool suitable for the energy storage valve control device is proposed. Specifically, a plurality of functional simulation transceiver interfaces for simulating the behavior of the external interfaces of the energy storage valve control device to be tested are provided in the hardware module of the tooling. The functional simulation transceiver interfaces are correspondingly connected with the functional interfaces of the energy storage valve control device to be tested, receive the test status data, alarm data and degradation data fed back by the energy storage valve control device to be tested during the accelerated life test process, and transmit the test status data, alarm data and degradation data. In the above scheme, the functional simulation transceiver interface can simulate the behavior of the external interface of the energy storage valve control device to be tested, realize the control and feedback information interaction with the energy storage valve control device to be tested, and then can simulate various test conditions, and obtain the test status data, alarm data and degradation data of each test item of the energy storage valve control device to be tested in various accelerated life test processes. It can support accurate accelerated life test results of the energy storage valve control device to be tested based on the test status data, alarm data and degradation data, and realize accurate reliability evaluation.

[0094] like Figure 2 As shown, in some embodiments, the tooling includes a control module 400 that communicates with the hardware module 200;

[0095] The control module 400 is used to receive the test status data, alarm data and degradation data sent by the functional simulation transceiver interface, perform reliability evaluation based on the test status data and alarm data to obtain the reliability evaluation result of the energy storage valve control device to be tested, and perform performance attenuation evaluation based on the degradation data to obtain the performance attenuation evaluation result of the energy storage valve control device to be tested.

[0096] In this embodiment, the energy storage valve control device test tool includes a hardware module 200 and a control module 400. Among them, the control module 400 receives the test state data, alarm data and degradation data sent by the functional simulation transceiver interface, performs reliability evaluation according to the test state data and alarm data, obtains the reliability evaluation result of the energy storage valve control device to be tested, and performs performance attenuation evaluation according to the degradation data. That is, the tool in this embodiment can realize the functions of data acquisition and data processing, and obtain the aging test result of the energy storage valve control device to be tested.

[0097] In practical applications, reliability assessment based on test status data and alarm data can be reliability assessment of local devices or reliability assessment of the entire product. In this embodiment, taking the reliability assessment of the communication interface of the SMC board as an example, it can be based on the test status data and alarm data fed back by the SMC board to determine whether each communication interface has a link break / packet loss / verification failure alarm, whether the bypass switch and the confluence switch have a wrong trigger signal, whether the IGBT has a trigger signal failure, and other issues. For example, whether the signal is triggered wrongly can be determined by comparing the known optical signal mode and switch state, as well as the mode of the received optical signal fed back by the SMC board, to determine whether the bypass switch or the confluence switch of the SMC board has an abnormality or a false trigger signal. For example, if the optical signal mode of the bypass switch analog transceiver interface or the confluence switch analog transceiver interface is a constant signal, indicating that the switch is in a closed state, and the state data fed back by the SMC board indicates that it receives an optical signal, which is inconsistent with expectations, then it can be determined that the bypass switch or the confluence switch detection function of the SMC board is abnormal.

[0098] In another embodiment, the process of conducting reliability assessment on the energy storage valve control device to be tested as a whole may be: preprocessing the collected test status data and alarm data, removing outliers, filling missing values, and other operations to ensure the accuracy and integrity of the data. Then, statistical analysis and modeling are performed on the preprocessed data to obtain indicators such as the failure rate, failure probability, and mean repair time of the energy storage valve control device to be tested, which can be used to evaluate the reliability level. Based on the indicators obtained by the analysis, the corresponding evaluation method is used to evaluate the reliability of the energy storage valve control device to be tested, and a reliability result is obtained.

[0099] The performance degradation evaluation according to the degradation data can be performed by calculating the index value of the energy storage valve control device to be tested with respect to a specific evaluation index based on the degradation data, and then comparing whether the error between the index value and the standard index value exceeds the preset error allowable range. If it exceeds, it indicates that the energy storage valve control device to be tested has performance degradation. Furthermore, if the performance degradation evaluation is performed periodically, a curve of the performance degradation evaluation result changing with time can be obtained based on the periodic performance degradation evaluation result.

[0100] In the technical solution of the embodiment of the present application, by providing a control module, reliability evaluation can be performed based on test status data and alarm data, and performance attenuation evaluation can be performed based on degradation data, thereby enabling accurate reliability evaluation and performance attenuation evaluation of the energy storage valve control device to be tested.

[0101] In some embodiments, the control module 400 is used to perform data initialization, and send command data and state feedback data to the energy storage valve control device to be tested through a functional simulation transceiver interface, so that the energy storage valve control device to be tested can operate normally.

[0102] The instruction data may be normal instruction data, which may be specifically presented in the form of communication message data. After the energy storage valve control device to be tested receives the instruction data, fault clearing can be achieved. State feedback data refers to data that characterizes the state of certain components of the energy storage valve control device to be tested under a simulated environment, for example, a switch separation state feedback signal. Following the previous embodiment, the control module may also perform data initialization on the tooling before performing reliability assessment and performance attenuation assessment. Specifically, it may be by loading a preset configuration file during the initialization process to configure the interface of the functional simulation transceiver interface. Further, the functional simulation transceiver interface outputs corresponding communication message data and switch state feedback signals to the energy storage valve control device to be tested. After the energy storage valve control device to be tested receives the communication message data and feedback signals, fault clearing is performed and the device operates in a normal state. At the same time, the control module may collect the accelerated life test feedback data of the energy storage valve control device to be tested in the current operating state. If the accelerated life test feedback data is normal, the accelerated life test is continued. If it is abnormal, the energy storage valve control device to be tested is determined to be failed.

[0103] In the technical solution of the embodiment of the present application, the control module can be used to enable the energy storage valve control device to be tested to operate normally, and at the same time can collect accelerated life test feedback data of the energy storage valve control device to be tested under the current operating state, so as to perform a more accurate reliability assessment and performance attenuation assessment on the energy storage valve control device to be tested.

[0104] like Figure 3 As shown, in some embodiments, the control module 400 includes a lower computer 420 and a digital circuit chip 440 that communicate with each other, and the digital circuit chip 440 communicates with the hardware module 200;

[0105] The lower computer 420 is used to send the interface configuration data to the digital circuit chip 440 and perform performance degradation evaluation according to the degradation data to obtain the performance degradation evaluation result of the energy storage valve control device to be tested.

[0106] The digital circuit chip 440 is used to configure the interface parameters of the functional analog transceiver interface 220 according to the interface configuration data, and to perform reliability evaluation according to the test status data and the alarm data, to obtain the reliability evaluation result of the energy storage valve control device to be tested, and to send the reliability evaluation result to the lower computer 420.

[0107] The lower computer usually refers to hardware devices such as embedded systems, single-chip microcomputers or microcontrollers. In this embodiment, the lower computer 420 can be used to perform real-time control and monitoring of the energy storage valve control device to be tested. The digital circuit chip 440 is a micro integrated circuit that can realize digital logic operations, which includes a programmable logic device such as an FPGA (Field-Programmable Gate Array), a processor or a memory. In this embodiment, the digital circuit chip 440 takes an FPGA chip as an example.

[0108] In a specific implementation, the lower computer 420 may respond to a test task, send interface configuration data to the FPGA chip, the FPGA chip receives the interface configuration data, configures the functional simulation transceiver interface according to the interface configuration data, and receives the test status data and alarm data fed back by the functional simulation transceiver interface to perform reliability assessment, perform reliability assessment based on the test status data and the alarm data, obtain the reliability assessment result of the energy storage valve control device to be tested, and send the reliability assessment result to the lower computer 420.

[0109] The lower computer 420 receives the degradation data fed back by the functional simulation transceiver interface, performs performance degradation evaluation according to the degradation data, and obtains the performance degradation evaluation result of the energy storage valve control device to be tested. It can be understood that in other embodiments, the FPGA chip can perform performance degradation evaluation according to the degradation data in addition to reliability evaluation; similarly, the lower computer 420 can also perform reliability evaluation according to the test status data and alarm data in addition to performance degradation evaluation according to the degradation data, which can be determined according to the real-time requirements of the evaluation results. If the evaluation results have high real-time requirements, the evaluation can be performed through the FPGA chip, and if the evaluation results do not have high real-time requirements, the evaluation can be performed through the lower computer 420.

[0110] In the technical solution of the embodiment of the present application, by disassembling the control module into a lower computer and a digital circuit chip, the flexibility of data processing can be improved through the coordinated cooperation of the lower computer and the digital circuit chip, and more complex logical functions can be realized by combining digital circuit chips to cope with more complex testing requirements.

[0111] like Figure 4 As shown, in some embodiments, the tooling further includes a host computer 100, and the host computer 100 communicates with the slave computer 420 through a network;

[0112] The upper computer 100 is used to send control commands and tooling configuration data to the lower computer 420 , and receive and display the performance degradation evaluation results and reliability evaluation results sent by the lower computer 420 .

[0113] The lower computer 420 is also used to send control commands and tooling configuration data to the digital circuit chip 440 , and send the received performance degradation evaluation results and reliability evaluation results of the energy storage valve control device to be tested to the upper computer 100 .

[0114] The host computer 100 refers to a computer system that processes data, monitors the control process and performs human-computer interaction for a certain control system. It can communicate with the lower computer 420 through serial ports, Ethernet, USB (Universal Serial Bus) and other methods, and can also exchange data and communicate with other computer systems or networks. The host computer 100 is responsible for the design and implementation of the human-computer interaction interface, as well as processing and displaying the data collected by the lower computer 420, sending control instructions to the lower computer 420, and monitoring the operating status of the control system in real time. The tooling configuration data may include communication configuration data and interaction configuration data, etc. The communication configuration data may include the communication type, communication cycle and communication length of each functional simulation transceiver interface. The interaction configuration data may include configuration data of variables to be controlled and state data to be fed back in the interaction with the energy storage valve control device to be tested.

[0115] In this embodiment, the lower computer 420 serves as a bridge between the upper computer 100 and the digital circuit chip 440 to achieve communication between the two. Specifically, the upper computer 100 is used to send control commands and tooling configuration data to the lower computer 420, and the lower computer 420 sends the control commands and tooling configuration data to the digital circuit chip 440, and the digital circuit chip 440 sends the control commands to the functional analog transceiver interface and completes the corresponding configuration according to the tooling configuration data. The lower computer 420 is also used to send the performance attenuation evaluation results and reliability evaluation results of the energy storage valve control device to be tested to the upper computer 100. After receiving the performance attenuation evaluation results and reliability evaluation results, the upper computer 100 can display the received performance attenuation evaluation results and reliability evaluation results, and specifically display the data through a graphical interface, so that the tester can view the status of the energy storage valve control device to be tested during the aging test process in real time.

[0116] In the technical solution of the embodiment of the present application, by providing a host computer, the test status and results can be displayed through the human-machine interface of the host computer, which is convenient for operators to make quick judgments and analyses, and remote monitoring and control functions can also be realized, which is convenient for technical personnel to perform remote maintenance.

[0117] In some embodiments, the upper computer 100 is further used to send a data acquisition accuracy test task to the lower computer 420, and perform a functional test and a performance test on the energy storage valve control device to be tested during the accelerated life test process;

[0118] The digital circuit chip 440 is used to receive the degradation data fed back by the energy storage valve control device to be tested and sent by the functional analog transceiver interface, decode and convert the degradation data to obtain the degradation data measurement value, and send the degradation data measurement value to the lower computer 420.

[0119] The lower computer 420 is used to determine the data acquisition accuracy of the energy storage valve control device to be tested according to the degradation data measurement value and the actual measurement standard value, and obtain the performance degradation evaluation result of the energy storage valve control device to be tested according to the data acquisition accuracy and a preset data acquisition accuracy threshold.

[0120] The data acquisition accuracy test task refers to testing the data acquisition accuracy of the energy storage valve control device to be tested. Based on the data acquisition accuracy test results, performance degradation evaluation can be achieved. In specific implementation, the upper computer 100 may start the test, and the tester may select the data acquisition accuracy test task on the human-computer interaction interface. At this time, the upper computer 100 sends the data acquisition accuracy test task to the lower computer 420, and controls and adjusts the corresponding accelerated life test conditions to test the energy storage valve control device to be tested. At this time, the energy storage valve control device to be tested may collect degradation data during the test, and feed back the collected degradation data to the functional analog transceiver interface through a communication message, and the functional analog transceiver interface then sends the degradation data to the digital circuit chip 440, and the digital circuit chip 440 performs interface data parsing processing on the received degradation data, that is, performs decoding conversion to read out the actual degradation data measurement value, and then sends the read degradation data actual measurement value to the lower computer 420, and the lower computer 420 may compare the degradation data measurement value with the actual measurement standard value, calculate the data acquisition accuracy of the energy storage valve control device to be tested, and then obtain the performance attenuation evaluation result of the energy storage valve control device to be tested according to the data acquisition accuracy and a preset data acquisition accuracy threshold. For example, the error between the data acquisition accuracy and the preset data acquisition accuracy threshold is calculated, and then the error is compared to see whether it exceeds the preset error tolerance range. If it exceeds, it is determined that the energy storage valve control device to be tested has performance degradation, and the performance degradation evaluation result is obtained. Furthermore, if the data acquisition accuracy test is performed periodically, a curve of the performance degradation evaluation result changing over time can be obtained based on the periodic data acquisition accuracy.

[0121] For example, taking the calculation of the capacitor voltage acquisition accuracy of the SMC board to be tested as an example, the host computer 100 may start the test, and the tester may select the capacitor voltage acquisition test task on the human-computer interaction interface of the host computer 100, and control the external adjustable high-voltage power supply to output the voltage value of each test point. The SMC board to be tested collects the voltage measurement value of each test point, and sends the voltage measurement value to the VBC analog communication interface through the communication message. The VBC analog communication interface sends the voltage measurement value to the FPGA chip. The FPGA chip performs a series of processing such as data parsing, decoding and unit conversion on the communication message according to the specific communication protocol. , convert the voltage measurement value into a readable digital voltage measurement value, and send the converted voltage measurement value to the lower computer, then the lower computer 420 reads the voltage measurement value, and calculates the data accuracy based on the voltage measurement value and the preset voltage standard value of the power supply output. For example, if the voltage standard value is 5V, the voltage measurement value fed back by the SMC board is 4.8V, then the data acquisition accuracy is 4.8÷5*100%=96%, and the error of the data acquisition accuracy is (5-4.8) / 5*100%=4%. The error of 4% exceeds the preset error allowable range such as 1% to 2%, and it is determined that the SMC has performance degradation. Further, according to the periodic accuracy results, a curve of the performance degradation evaluation result changing with time can be obtained. It can be understood that if the real-time requirements for data processing are not high, the performance degradation evaluation process based on the data acquisition accuracy calculation can also be implemented by the lower computer 420.

[0122] In the technical solution of the embodiment of the present application, by calculating the data collection accuracy of the energy storage valve control device to be tested, the performance attenuation evaluation of the energy storage valve control device to be tested can be realized.

[0123] In some embodiments, the host computer 100 is further used to send a control link delay test task to the digital circuit chip 440 through the slave computer 420;

[0124] The digital circuit chip 440 is also used to respond to the control link delay test task, send control commands to the energy storage valve control device to be tested through the functional simulation transceiver interface, and record the command sending time, and receive feedback commands sent by the energy storage valve control device to be tested through the functional simulation transceiver interface, and record the command receiving time, determine the control link delay according to the command sending time and the command receiving time, and obtain the performance attenuation evaluation result of the energy storage valve control device to be tested according to the control link delay and the preset control link delay threshold.

[0125] The control link refers to a channel for transmitting control information from a source device to a target device. In this embodiment, the control link may be a channel for transmitting control commands between a tool and a storage valve control device to be tested. The control link delay test refers to a method for measuring the delay of a control link. Generally speaking, the control link delay test may be achieved by calculating indicators such as the average delay, maximum delay, and packet loss rate of control commands in the control link.

[0126] In some embodiments, the upper computer 100 may send a control link delay test task to the digital circuit chip 440 through the lower computer 420. The digital circuit chip 440 responds to the control link delay test task, sends a control command to the energy storage valve control device to be tested through the functional simulation transceiver interface, and records the command sending time T1. After receiving the control command, the energy storage valve control device to be tested will make a corresponding response, and receive a feedback command to the tooling through the functional simulation transceiver interface. At this time, the digital circuit chip 440 receives the feedback command sent by the energy storage valve control device to be tested through the functional simulation transceiver interface, and records the command receiving time T2. Based on the command sending time T1 and the command receiving time T2, the control link delay is determined, that is, the control link delay = command receiving time T1-command sending time T2. Then, it is compared whether the control link delay exceeds the preset control link delay threshold. If it exceeds, it is determined that the energy storage valve control device to be tested has performance degradation, and a performance degradation evaluation result is obtained.

[0127] Similarly, taking the control link delay of the SMC board to be tested as an example, the host computer 100 can start the test, and the tester selects the control link delay test task on the human-computer interaction interface of the host computer 100. The simulated VBC interface of the tooling sends the IGBT conduction command to the SMC board to be tested through the protocol message. At this time, the FPGA chip adds a timestamp and records the command sending time T1; the SMC board to be tested sends the IGBT trigger conduction command after receiving the control command, and the tooling receives this IGBT trigger conduction command through the IGBT simulation interface. At this time, the FPGA chip records the command receiving time T2, and then the FPGA chip calculates the difference between the command sending time T1 and the command receiving time T2, which is the control link delay of the SMC board (such as 100 microseconds). Then, compare whether the calculated delay exceeds the preset delay allowable error range. If it exceeds, it is determined that the energy storage valve control device to be tested has performance degradation, and if it does not exceed, it is determined that there is no performance degradation. During the test, the control link delay can be tested at a certain period, and the attenuation of the control link delay performance can be obtained based on the periodic control link delay.

[0128] The technical solution of the embodiment of the present application can quickly and accurately implement the performance degradation evaluation of the energy storage valve control device to be tested by testing the control link delay.

[0129] like Figure 5 As shown, in some embodiments, the tooling further includes a first power module 500, which is connected to the energy storage valve control device to be tested and is used to provide a stable power supply to the energy storage valve control device to be tested.

[0130] The first power module 500 is a power source for providing a stable power supply. Specifically, the first power module 500 is connected to the energy storage valve control device to be tested, and is used to provide a stable power supply to the energy storage valve control device to be tested. The first power module 500 may include but is not limited to a battery, a new energy battery panel, or a generator set.

[0131] In the technical solution of the embodiment of the present application, by providing a power supply module that provides a stable power supply, the possibility of tooling being affected by voltage instability, resulting in errors in test results, can be reduced, and the risk of tooling damage can be reduced.

[0132] like Figure 6 As shown, in some embodiments, the tooling further includes a second power module 600, which is connected to the energy storage valve control device to be tested and is used to provide an adjustable voltage to the energy storage valve control device to be tested.

[0133] The second power module 600 is a power module that can output an adjustable voltage. Specifically, the second power module 600 is connected to the energy storage valve control device to be tested, and is used to provide an adjustable voltage to the energy storage valve control device to be tested. In specific implementation, the second power module 600 can simulate the capacitor voltage and apply it to the energy storage valve control device to be tested, so that the energy storage valve control device to be tested can collect this simulated voltage value, and compare the voltage sampling value with the actual voltage output value to obtain the voltage collection accuracy, thereby realizing the voltage collection accuracy test. The second power module 600 can be a high-voltage adjustable power supply, including but not limited to a transformer-type power supply, an adjustable high-voltage linear power supply, and an adjustable high-voltage pulse power supply.

[0134] In the technical solution of the embodiment of the present application, by adding a power supply module that can output an adjustable voltage, the capacitor voltage can be simulated and applied to the energy storage valve control device to be tested. The energy storage valve control device to be tested collects this voltage to achieve voltage accuracy testing.

[0135] In some embodiments, the functional simulation transceiver interface includes a switch state simulation interface and a communication simulation interface for communicating with the energy storage valve control device to be tested.

[0136] The switch state simulation interface is a programming interface provided by the hardware module 200, which is used to simulate the state of the switch in the electronic device. In this embodiment, the switch state simulation interface is connected to the switch interface of the energy storage valve control device to be tested, and is used to simulate the state of the switch in the energy storage valve control device to be tested. The communication simulation interface refers to an interface used to simulate the electronic device sending a communication message. It can simulate various situations in the communication process, such as signal interference, frequency offset, delay, etc., and generate corresponding data output.

[0137] Following the above embodiment, referring to the functional simulation transceiver interface of the SMC board to be tested, the switch state simulation interface includes a convergence switch simulation interface, a bypass switch simulation interface and an IGBT simulation interface, and the communication simulation interface includes a VBC simulation interface and a BMC simulation interface.

[0138] In the technical solution of the embodiment of the present application, by providing a switch state simulation interface and a communication simulation interface, an interface for communication test and switch control test items in the accelerated life test is provided, which can quickly simulate various test conditions and obtain multiple test evaluation results, so as to achieve accurate evaluation of the energy storage valve control device to be tested.

[0139] In order to clearly illustrate the energy storage valve control device test tool provided in the present application, the energy storage valve control device test tool is an SMC board test tool, and the energy storage valve control device to be tested is an SMC board (referred to as SMC) as an example, and combined with the attached Figure 7 To explain:

[0140] like Figure 7 As shown, the SMC board test tooling includes a host computer 710, a hardware module 720, a power supply module 740, an adjustable high-voltage power supply module 760, a slave computer (not shown in the figure) and an FPGA chip (not shown in the figure). Among them, the host computer communication interface 712 of the host computer 710 is connected to the slave computer communication interface 722 to realize the network communication between the host computer 710 and the slave computer. The hardware module 720 includes a lower computer communication interface 722, a confluence switch analog transceiver interface 724, a bypass switch analog transceiver interface 726, a VBC analog transceiver interface 728, a BMC analog transceiver interface 730 and an IGBT analog transceiver interface 732, wherein the confluence switch analog transceiver interface 724, the bypass switch analog transceiver interface 726, the VBC analog transceiver interface 728, the BMC analog transceiver interface 730 and the IGBT analog transceiver interface 732 are all functional analog transceiver interfaces, wherein the confluence switch analog transceiver interface 724, the IGBT analog transceiver interface 732 and the bypass switch analog transceiver interface 726 are switch state analog transceiver interfaces, and the VBC analog transceiver interface 728 and the BMC analog transceiver interface 730 are communication analog interfaces for communicating with the SMC.

[0141] In some embodiments, the present application also provides an accelerated life test method based on a test fixture for an energy storage valve control device provided in an embodiment, which can be applied to Figure 5 or Figure 6 In the interaction diagram of the energy storage valve control device test tooling and the energy storage valve control device to be tested shown. Specifically, the tooling can send command data and state feedback data to the energy storage valve control device to be tested through the functional simulation transceiver interface to enable the energy storage valve control device to be tested to operate normally, and then start the preset high and low temperature test chamber program, heat up to the aging test temperature, and start the accelerated life test of the energy storage valve control device to be tested. Subsequently, the test state data, alarm data and degradation data fed back by the energy storage valve control device to be tested during the accelerated life test process sent by the functional simulation transceiver interface are received, and reliability evaluation is performed based on the test state data and alarm data to obtain the reliability evaluation result of the energy storage valve control device to be tested, and performance attenuation evaluation is performed based on the degradation data to obtain the performance attenuation evaluation result of the energy storage valve control device to be tested.

[0142] In some embodiments, Figure 8 As shown, an accelerated life test method based on a test fixture for an energy storage valve control device is provided. Figure 1 The energy storage valve control device test tooling in the example is used to illustrate, including the following steps:

[0143] Step S202 , sending command data and state feedback data to the energy storage valve control device to be tested through the functional simulation transceiver interface, so that the energy storage valve control device to be tested operates normally.

[0144] The command data may be normal command data, which may be specifically presented in the form of communication message data. State feedback data refers to data that characterizes the state of certain components of the energy storage valve control device to be tested under a simulated environment, for example, a switch separation state feedback signal. The tooling in this embodiment is a tooling with a control module and a hardware module. The tooling can output corresponding communication message data and switch state feedback signals to the energy storage valve control device to be tested through a functional simulation transceiver interface. After the energy storage valve control device to be tested receives the communication message data and feedback signals, the fault is cleared and the device operates in a normal state.

[0145] Step S204, receiving the test status data, warning data and degradation data fed back by the energy storage valve control device to be tested during the accelerated life test process, which are sent by the functional simulation receiving and sending interface.

[0146] The test status data may also be referred to as the aging test status data, which are various status parameters collected when the energy storage valve control device to be tested is subjected to an aging test. These data include data from multiple aspects such as electrical parameters, communication alarm parameters, and board self-test status, which are used to evaluate the reliability and life of the energy storage valve control device to be tested. Degradation data are product status parameters that gradually change with time or the increase in the number of uses. After the energy storage valve control device to be tested operates normally, the preset accelerated life test program can be started to perform an accelerated life test on the energy storage valve control device to be tested according to the preset accelerated life test conditions. In this embodiment, the preset high and low temperature test chamber program can be started, the temperature is raised to the aging test temperature, and the accelerated life test of the energy storage valve control device to be tested is started. During the accelerated life test, the energy storage valve control device to be tested can feedback the collected test status data, alarm data, and degradation data to the tooling through the functional simulation transceiver interface.

[0147] Step S206, performing reliability evaluation according to the test state data and the alarm data to obtain a reliability evaluation result of the energy storage valve control device to be tested, and performing performance attenuation evaluation according to the degradation data to obtain a performance attenuation evaluation result of the energy storage valve control device to be tested.

[0148] After receiving the test status data, alarm data and degradation data, the tooling can process the test status data, alarm data and degradation data through the built-in control module to realize the accelerated life test evaluation of the energy storage valve control device to be tested. Specifically, the reliability evaluation can be performed based on the test status data and alarm data to obtain the reliability evaluation result of the energy storage valve control device to be tested, and the performance attenuation evaluation can be performed based on the degradation data to obtain the performance attenuation evaluation result of the energy storage valve control device to be tested.

[0149] In the technical solution of the embodiment of the present application, by sending command data and state feedback data to the energy storage valve control device to be tested through the functional simulation transceiver interface, the energy storage valve control device to be tested can be operated normally, which is conducive to the smooth progress of the test process. Based on the test state data, alarm data and degradation data fed back by the energy storage valve control device to be tested during the accelerated life test, accurate reliability evaluation and performance attenuation evaluation can be achieved. In summary, the use of this solution can quickly and accurately achieve the accelerated life test evaluation of the energy storage valve control device to be tested.

[0150] In some embodiments, a performance attenuation evaluation is performed based on the degradation data to obtain a performance attenuation evaluation result of the energy storage valve control device to be tested, including: decoding and converting the degradation data to obtain a degradation data measurement value, determining a data acquisition accuracy of the energy storage valve control device to be tested based on the degradation data measurement value and an actual measurement standard value, and obtaining a performance attenuation evaluation result of the energy storage valve control device to be tested based on the data acquisition accuracy and a preset data acquisition accuracy threshold.

[0151] In the technical solution of the embodiment of the present application, by performing a data acquisition accuracy test on the energy storage valve control device to be tested, a performance attenuation evaluation of the energy storage valve control device to be tested can be achieved.

[0152] In specific implementation, the host computer 100 may start the test, and the tester may select the data acquisition accuracy test task on the human-computer interaction interface of the host computer 100. At this time, the host computer 100 sends the data acquisition accuracy test task to the slave computer 420, and controls and adjusts the corresponding accelerated life test conditions to test the energy storage valve control device to be tested. At this time, the energy storage valve control device to be tested may collect degradation data during the test, and feed the collected degradation data back to the functional simulation transceiver interface through the communication message, and the functional simulation transceiver interface then feeds the degradation data back to the slave computer 420. The data is sent to the digital circuit chip 440, and the digital circuit chip 440 performs interface data analysis processing on the received degradation data, that is, performs decoding conversion to read out the actual degradation data measurement value, and then sends the read degradation data actual measurement value to the lower computer 420. The lower computer 420 can compare the degradation data measurement value with the actual measurement standard value, calculate the data acquisition accuracy of the energy storage valve control device to be tested, and then obtain the performance attenuation evaluation result of the energy storage valve control device to be tested based on the data acquisition accuracy and the preset data acquisition accuracy threshold. For example, the error between the data acquisition accuracy and the preset data acquisition accuracy threshold is calculated, and then the error is compared to see whether it exceeds the preset error allowable range. If it exceeds, it is determined that the energy storage valve control device to be tested has performance attenuation, and the performance attenuation evaluation result is obtained. Furthermore, if the data acquisition accuracy test is performed periodically, a curve of the performance attenuation evaluation result changing over time can also be obtained based on the periodic data acquisition accuracy.

[0153] In some embodiments, a performance degradation evaluation is performed based on the degradation data to obtain a performance degradation evaluation result of the energy storage valve control device to be tested, including: sending a control command to the energy storage valve control device to be tested and recording the command sending time, receiving a feedback command sent by the energy storage valve control device to be tested and recording the command receiving time, determining a control link delay based on the command sending time and the command receiving time, and obtaining a performance degradation evaluation result of the energy storage valve control device to be tested based on the control link delay and a preset control link delay threshold.

[0154] In a specific implementation, the upper computer 100 may send a control link delay test task to the digital circuit chip 440 through the lower computer 420. The digital circuit chip 440 responds to the control link delay test task, sends a control command to the energy storage valve control device to be tested through the functional simulation transceiver interface, and records the command sending time T1. After receiving the control command, the energy storage valve control device to be tested will make a corresponding response, and send a feedback command to the tooling through the functional simulation transceiver interface. At this time, the digital circuit chip 440 receives the feedback command sent by the energy storage valve control device to be tested through the functional simulation transceiver interface, and records the command receiving time T2, the command sending time T1 and the command receiving time T2, and determines the control link delay, that is, the control link delay = command receiving time T1-command sending time T2. Then, it is compared whether the control link delay exceeds the preset control link delay threshold. If it exceeds, it is determined that the energy storage valve control device to be tested has performance degradation, and a performance degradation evaluation result is obtained.
