Description

Technical Field

[0002] Vehicle-to-grid (V2G) technology offers a new solution for grid balancing and emergency response. It allows electric vehicles to charge from the grid during off-peak hours and discharge back to the grid during peak hours, thereby optimizing the allocation of power resources. V2G technology not only helps the grid regulate voltage and frequency, improving power supply reliability, but also provides additional power to the grid, enhancing the intelligence and stability of the new power system.

[0003] However, when using charging and discharging equipment equipped with V2G technology for bidirectional charging and discharging, problems such as the inability to communicate between electric vehicles and charging and discharging equipment will arise. As a result, when implementing V2G technology, the control of interoperability during the charging and discharging process of electric vehicles is uncertain, and it is impossible to effectively avoid the impact of poor interoperability on the charging and discharging process during the charging and discharging process, which in turn affects the performance of electric vehicle batteries and may bring risks to the stability and security of the power grid.

[0004] When current charging and discharging equipment performs bidirectional charging and discharging operations, in the event of interoperability anomalies, the fault can only be handled when a problem occurs, which reduces the timeliness of fault handling and may cause unnecessary failures in the charging and discharging equipment or electric vehicles, affecting the safe operation of the equipment.

[0029] For ease of description, some nouns or terms involved in the embodiments of the present application are explained below:

[0030] Interoperability: In the scenario of electric vehicle charging and discharging and grid interaction technology (V2G), device interoperability specifically refers to the compatibility and collaborative working capabilities between electric vehicles, charging stations (charging piles), and grid management systems. It includes:

[0031] Interoperability between electric vehicles and charging stations: Electric vehicles can effectively connect and charge with charging stations from different manufacturers without requiring special configuration or modification of the vehicle or charging station. This typically involves standardization of charging interface standards, communication protocols, and security mechanisms.

[0032] Interoperability between charging piles and the power grid: Charging piles can adjust their charging and discharging strategies based on grid signals or instructions, such as responding to changes in grid frequency and voltage, or feeding power back to the grid when needed, without the need for additional customized software or hardware.

[0033] System-level interoperability: Electric vehicles, charging piles, and grid management systems can exchange information such as vehicle status, charging requests, and charging and discharging plans by following standardized communication protocols, thereby supporting functions such as smart charging, demand response, and power balancing.

[0034] ChaoJi standard: an electric vehicle charging interface standard.

[0035] According to an embodiment of the present application, a method for detecting interoperability of charging and discharging devices is provided.

[0036] Figure 1 This is a flow chart of a method for detecting interoperability of charging and discharging devices according to an embodiment of the present application. Figure 1 As shown, the method includes the following steps:

[0037] Step S101 : controlling the charging and discharging equipment to connect to a test system, wherein the test system includes a power grid system and a vehicle system.

[0038] It should be noted that charging and discharging equipment refers to devices that can charge electric vehicles and discharge electricity from them back to the power grid, such as charging piles or bidirectional charging and discharging equipment. The test system can include a power grid system that simulates the power grid environment and a vehicle system that simulates electric vehicles. These systems are used to test the performance of charging and discharging equipment in different scenarios. The power grid system can simulate various operating conditions of the power grid, such as voltage and frequency fluctuations, as well as normal and abnormal conditions of the communication network. The vehicle system can simulate the BMS (Battery Management System) and charging and discharging characteristics of the electric vehicle, including communication protocols, charging and discharging parameters, and the battery's charging and discharging status.

[0039] Specifically, before testing the charging and discharging equipment, it must first be physically connected to the power grid and vehicle systems in the test system. The test system then controls the charging and discharging equipment to establish communication with the simulated vehicle and power grid to ensure that the charging and discharging equipment can accurately identify and respond to signals from the vehicle and power grid.

[0040] For example, before testing, a ChaoJi-compliant charging and discharging device is connected to the vehicle system (simulating the BMS) and the power grid system (simulating the power grid's communication environment) in the test system. By controlling the test system and simulating the normal communication process under the ChaoJi standard, the charging and discharging device can be verified to correctly identify the vehicle and establish a charging and discharging connection.

[0041] Step S102 : operating the charging and discharging equipment, and performing performance tests on the charging and discharging equipment according to the performance test process of M test items, to obtain M test results, where M is a positive integer.

[0042] It should be noted that the "test items" refer to the specific test points to be performed during interoperability testing, with each test point corresponding to a specific performance or function of the charging and discharging equipment. The "performance testing process" refers to the series of test steps and conditions designed for each test item to evaluate the performance of the charging and discharging equipment under that test item.

[0043] Specifically, after successfully connecting to the test system, the charging and discharging equipment starts to run. When the charging and discharging equipment runs smoothly, the test system will determine the detection process for testing the operating performance of the charging and discharging equipment one by one according to the pre-set M detection items, including but not limited to communication function, discharge control function, discharge connection control timing, charge and discharge conversion function and on-grid switching function, etc., to detect the behavior and performance of the charging and discharging equipment under various situations, thereby obtaining M specific detection results.

[0044] It should be noted that different test items correspond to different test processes, and different test processes require the test system to perform different operations. Therefore, the various test processes cannot be executed in parallel, and need to be executed in sequence according to the execution order of the test items to ensure the accuracy of the test results of each test item.

[0045] For example, when testing ChaoJi-compliant charging and discharging equipment, the test system can perform M = 10 test items, including but not limited to the aforementioned communication functions and discharge control functions. During the communication function test, the charging and discharging equipment can be tested for its ability to reestablish a connection with the simulated power grid and vehicle after a communication interruption, and to charge and discharge normally, thereby obtaining the corresponding test results.

[0046] Step S103: determining an interoperability test result of the charging and discharging devices according to the M test results.

[0047] It should be noted that the interoperability test result is an overall evaluation of whether the charging and discharging equipment can achieve effective and safe energy and information exchange with the vehicle and the power grid after integrating M test results.

[0048] Specifically, after completing the performance testing process for M specific test items, the collected M test results are analyzed and summarized to determine the overall interoperability performance of the charging and discharging equipment. If the charging and discharging equipment can meet the expected performance standards and functional requirements in all test items, its interoperability test results will be considered "qualified" or "passed", thus completing the complete process of determining the interoperability test results of the charging and discharging equipment based on the test results.

[0049] For example, after completing all test items, if the charging and discharging equipment does not show any abnormalities or failures in all 10 test items such as communication function and discharge control function, the test system will combine these test results and determine that the interoperability test result of the charging and discharging equipment is "qualified", indicating that it can safely interact with electric vehicles and the power grid for charging and discharging. If the charging and discharging equipment is found to have performance problems or insufficient functions in any test item, the test system will determine its interoperability test result as "unqualified", and the charging and discharging equipment needs to be improved or repaired before retesting, thereby avoiding operational failures of the charging and discharging equipment and ensuring that the charging and discharging equipment can operate normally.

[0050] The method for detecting the interoperability of charging and discharging equipment provided in the embodiment of the present application is to control the charging and discharging equipment to be connected with a test system, wherein the test system includes a power grid system and a vehicle system; operate the charging and discharging equipment, and perform performance tests on the charging and discharging equipment according to the performance test process of M test items, to obtain M test results, wherein M is a positive integer; determine the interoperability test results of the charging and discharging equipment according to the M test results, thereby solving the problem of low timeliness in processing the charging and discharging equipment in the related art when an interoperability failure occurs in the charging and discharging equipment. By connecting the charging and discharging equipment to the test system and performing performance tests on the charging and discharging equipment according to the test items while the charging and discharging equipment is operating normally, it is determined whether there is an abnormality in the interoperability of the charging and discharging equipment according to the performance test results, and then it is determined in advance whether there is an abnormality in the charging and discharging equipment according to the interoperability test results, and the charging and discharging equipment is promptly maintained in the event of an abnormality, thereby achieving the technical effect of improving the timeliness of maintenance processing of the charging and discharging equipment.

[0051] Optionally, in the method for detecting the interoperability of charging and discharging equipment provided in an embodiment of the present application, when the detection item is communication interoperability detection, the performance of the charging and discharging equipment is respectively detected according to the performance detection process of M detection items, and M detection results are obtained, including: sending synchronization information to the charging and discharging equipment through the vehicle system, and determining that the communication interoperability detection result is abnormal when it is detected that the charging and discharging equipment does not obtain the synchronization information sent by the vehicle system; when it is detected that the charging and discharging equipment obtains the synchronization information sent by the vehicle system, sending a control instruction to the charging and discharging equipment through the test system, and when the charging and discharging equipment does not respond to the control instruction, determining that the communication interoperability detection result is abnormal; when the charging and discharging equipment responds to the control instruction, interrupting the communication connection between the charging and discharging equipment and the vehicle system, and sending a communication restoration request to the charging and discharging equipment through the vehicle system; when the charging and discharging equipment receives the communication restoration request and restores the communication connection with the vehicle system based on the communication restoration request, determining that the communication interoperability detection result is normal; when the charging and discharging equipment does not receive the communication restoration request, or does not restore the communication connection with the vehicle system based on the communication restoration request, determining that the communication interoperability detection result is abnormal.

[0052] It's important to note that communication interoperability testing evaluates the stability and reliability of communication between the charging and discharging equipment and the vehicle system. Synchronization information refers to the signals sent by the vehicle system to the charging and discharging equipment during communication to establish and maintain communication synchronization. Control instructions refer to commands sent by the test system to the charging and discharging equipment to instruct the equipment to perform specific actions or transition states. A communication restoration request refers to a request sent by the vehicle system to the charging and discharging equipment to reestablish the communication connection after a communication interruption.

[0053] Specifically, when testing interoperability, it's first necessary to ensure that the charging and discharging equipment is connected to the vehicle system in the test system. Then, the interoperability test process begins to verify whether the charging and discharging equipment can receive synchronization information from the vehicle system. After the vehicle system and the charging and discharging equipment are connected, synchronization information can be sent to the charging and discharging equipment through the vehicle system, and the test system monitors whether the charging and discharging equipment successfully receives the synchronization information sent by the vehicle system. If the charging and discharging equipment fails to successfully receive the synchronization information, the system determines that the interoperability test result is abnormal, indicating a problem with the basic communication connection between the equipment and the vehicle.

[0054] When the charging and discharging device successfully obtains synchronization information, the test system can send control instructions to the charging and discharging device, such as requiring the device to start charging or discharging, so as to determine the charging and discharging device's ability to respond to the control instructions. If the charging and discharging device does not respond to the control instructions, the communication interoperability detection result is determined to be abnormal. If the charging and discharging device responds to the control instructions, it can be determined that the charging and discharging device can respond to the control instructions normally. At this time, it is also necessary to detect whether the charging and discharging device can restore communication normally in the scenario where the communication connection is interrupted.

[0055] At this time, the communication connection between the charging and discharging equipment and the vehicle system can be interrupted, and then the vehicle system sends a request to resume communication, so as to evaluate the ability of the charging and discharging equipment to re-establish the connection after the communication interruption, and ensure that the charging and discharging equipment can quickly resume communication with the vehicle after a short communication failure, so as to avoid possible safety risks during the charging and discharging process.

[0056] Furthermore, after sending the communication restoration request, the test system needs to observe whether the charging and discharging device can receive and respond to the restoration request and re-establish a communication connection with the vehicle system. If the charging and discharging device successfully responds, it indicates that it has good communication restoration capabilities and the communication interoperability test result is normal. If the device fails to respond or re-establish a connection, the test system determines that the communication interoperability test result is abnormal, and the communication interoperability test is completed.

[0057] For example, the charging and discharging equipment is configured to receive synchronization information under the ChaoJi standard. First, the test system simulates a normal communication environment to check whether the equipment can successfully obtain synchronization information. If not, the test is judged to be abnormal; if successful, the test system then sends a control command to start charging. After the equipment starts charging according to the command, the test system simulates a communication failure, such as disconnecting the S+ and S- communication lines, and then the vehicle system sends a request to resume communication through the test system. If the charging and discharging equipment can correctly receive the request to resume communication and re-establish communication, the test determines that its communication interoperability is normal; otherwise, it is judged to be abnormal.

[0058] Through the above implementation methods, this embodiment can comprehensively evaluate the interoperability of the charging and discharging equipment during the communication process with the vehicle system, ensuring that the charging and discharging equipment can not only work under normal communication conditions, but also quickly restore the connection after a communication failure, thereby ensuring the safety and continuity of the electric vehicle charging and discharging process.

[0059] Optionally, in the detection method for interoperability of charging and discharging equipment provided in an embodiment of the present application, when the detection item is insulation function detection, the performance of the charging and discharging equipment is respectively detected according to the performance detection process of M detection items, and M detection results are obtained, including: connecting a first resistor between the positive pole and the protective ground wire of the charging and discharging equipment, and judging whether the charging and discharging equipment is operating normally; when the charging and discharging equipment stops operating, determining that the insulation function of the charging and discharging equipment is abnormal; when the charging and discharging equipment is operating normally, replacing the first resistor with a second resistor, and judging whether the charging and discharging equipment is operating normally, wherein the second resistor is smaller than the first resistor; when the charging and discharging equipment is operating normally, determining that the insulation function of the charging and discharging equipment is abnormal; when the charging and discharging equipment stops operating, determining that the insulation function of the charging and discharging equipment is normal.

[0060] It should be noted that the insulation function test is used to evaluate whether the charging and discharging equipment has sufficient insulation capacity between the positive pole and the protective ground wire to ensure the safety of the equipment and users. Positive pole: The positive port that outputs electrical energy in the charging and discharging equipment, usually marked as DC+. Protective ground wire: A safety grounding wire that ensures that the equipment can safely conduct current back to the ground under abnormal conditions to reduce the risk of electric shock, usually marked as PE. First resistance: Used to simulate insulation resistance above the safety threshold. The standard value generally selected is 100Ω / V or higher. Second resistance: Used to simulate insulation resistance below the safety threshold. Generally, it is less than the selected value of the first resistance, for example, less than 100Ω / V.

[0061] Specifically, when testing the insulation function, it is first necessary to connect a first resistor (Rt1) between the positive pole (DC+) and the protective ground wire (PE) of the charging and discharging device under normal charging and discharging operation, thereby simulating the operating environment of the charging and discharging device under normal insulation conditions, and detecting whether the insulation detection function of the device can be started normally and monitor the insulation condition.

[0062] Observe whether the charging and discharging equipment can still operate normally after the first resistor is connected, including the charging and discharging status and communication status of the equipment. If the charging and discharging equipment operates normally after the first resistor is connected, it indicates that its insulation detection function is normal. If the charging and discharging equipment stops operating, it is determined that the insulation function of the charging and discharging equipment is abnormal. In other words, in the case of high impedance, the system can detect a minor insulation abnormality. In this case, only a corresponding warning prompt is required instead of directly interrupting charging, thereby ensuring the continuity of the charging process.

[0063] Furthermore, when the charging and discharging equipment is operating normally, the first resistor is replaced with the second resistor, that is, the insulation resistance between the charging interface and the ground is set to an excessively low state. At this time, a serious insulation fault is simulated. Then, when the charging and discharging equipment stops operating, it is determined that the insulation function is normal, that is, the insulation fault can be detected normally and the charging operation can be stopped in time, thereby completing the detection of the insulation function.

[0064] For example, in testing, if the sense resistor Rt is set to 450Ω / V and the charging preparation phase is simulated, the charging and discharging equipment should be able to identify a minor insulation anomaly, issue a warning, but continue charging. If the sense resistor Rt is set to 90Ω / V and the same charging preparation phase is simulated, the equipment should immediately detect a severe insulation fault, trigger a fault alarm, and prevent charging from commencing, thereby protecting personnel and equipment.

[0065] This embodiment simulates an insulation fault by setting the insulation resistance, ensuring that the charging and discharging equipment can respond correctly under different insulation conditions and automatically stop energy transmission to protect the safety of the equipment and users.

[0066] Optionally, in the detection method for interoperability of charging and discharging equipment provided in an embodiment of the present application, when the detection item is discharge control detection, the performance detection of the charging and discharging equipment is performed separately according to the performance detection process of M detection items, and M detection results are obtained, including: sending a discharge instruction to the charging and discharging equipment through the vehicle system, and judging whether the charging and discharging equipment performs a discharge operation to the vehicle system; when the discharge operation is not performed, determining that the discharge control detection result is abnormal; when the discharge operation is performed, changing the discharge power of the discharge operation through the vehicle system, and judging whether the discharge power of the charging and discharging equipment has changed; when the discharge power has changed, determining that the discharge control detection result is normal; when the discharge power has not changed, determining that the discharge control detection result is abnormal.

[0067] It should be noted that discharge control testing evaluates the charging and discharging equipment's ability to respond and dynamically adjust discharge power after receiving a discharge command from the vehicle system. A discharge command is a signal sent by the vehicle system to the charging and discharging equipment, instructing it to begin discharging into the electric vehicle battery. Discharge power is the amount of electrical power output by the charging and discharging equipment when discharging into the electric vehicle.

[0068] Specifically, when performing discharge control detection, it is necessary to send a discharge instruction to the charging and discharging device through the vehicle system, that is, to require the charging and discharging device to discharge to the vehicle system, and then verify whether the charging and discharging device can correctly receive the discharge instruction and start the discharge operation.

[0069] Furthermore, the test system observes whether the charging and discharging device responds to the discharge command and begins discharging the battery to the vehicle system. If the charging and discharging device does not discharge, the test system determines that the discharge control test result is abnormal, indicating that there is a problem with the device's response mechanism to the discharge command.

[0070] When the charging and discharging equipment has started to perform the discharge operation, it indicates that the charging and discharging equipment can respond normally to the discharge instruction. At this time, it is necessary to issue an instruction to change the discharge power through the vehicle system, for example, from 100kW to 50kW, so as to test whether the charging and discharging equipment can dynamically adjust its discharge power according to the real-time discharge power instruction.

[0071] When the discharge power of the charging and discharging equipment is changed according to the change instruction issued by the vehicle system, the characterization test system determines that the discharge control test result is normal, indicating that the discharge power control function of the equipment is effective. If the discharge power of the charging and discharging equipment is not changed according to the instruction, the test system will determine that the discharge control test result is abnormal, indicating that the equipment has defects in dynamically adjusting the discharge power, thereby completing the discharge control detection operation.

[0072] For example, if the charging and discharging equipment is in operation, the test system sends a discharge command to the equipment through the simulated vehicle system, requesting the charging and discharging equipment to discharge at a power of 100kW. The test system then monitors whether the charging and discharging equipment begins discharging. If the charging and discharging equipment begins discharging, the test system adjusts the discharge power command issued by the vehicle system to 50kW. The test system then observes whether the discharge power of the charging and discharging equipment is subsequently adjusted to 50kW. If the adjustment is successful, the test system records the discharge control test result as normal; if the charging and discharging equipment fails to respond to the power change command, the test system records the test result as abnormal.

[0073] This embodiment simulates the method of issuing discharge instructions to the charging and discharging device, ensuring that the charging and discharging device can normally receive the vehicle's instructions and perform corresponding discharge operations, thereby ensuring effective interoperability between the charging and discharging device and the vehicle.

[0074] Optionally, in the method for detecting the interoperability of charging and discharging devices provided in an embodiment of the present application, when the detection item is discharge time detection, the performance of the charging and discharging devices is respectively detected according to the performance detection process of M detection items, and M detection results are obtained, including: sending a discharge instruction to the charging and discharging device through the vehicle system, and judging whether the charging and discharging device performs a discharge operation to the vehicle system within a preset time; when the charging and discharging device performs a discharge operation to the vehicle system within the preset time, determining that the discharge time detection result is normal; when the charging and discharging device does not perform a discharge operation to the vehicle system within the preset time, determining that the discharge time detection result is abnormal.

[0075] It should be noted that discharge time detection evaluates whether the charging and discharging equipment can start and continue discharging within a preset time after receiving a discharge command, ensuring that the discharge response speed and sustainability of the charging and discharging equipment meet the requirements. The discharge command is the signal sent by the vehicle system to the charging and discharging equipment, instructing the equipment to discharge the electric vehicle battery.

[0076] Specifically, when performing discharge time detection, a discharge instruction is first sent to the charging and discharging device through the vehicle system, instructing the device to start discharging, thereby triggering the discharge mechanism of the charging and discharging device and starting the performance detection process.

[0077] It should be noted that after sending the discharge command, a preset duration, such as 5 seconds, needs to be set and a timer needs to be started. When the charging and discharging device performs the discharge operation, the test system determines whether the charging and discharging device performs the discharge operation to the vehicle system within the preset duration. If the charging and discharging device performs the discharge operation within the preset duration, it indicates that the device's response speed meets the requirements, and the test system will record the discharge time test result as normal. If the charging and discharging device fails to perform the discharge operation within the preset duration, the test system will record the discharge time test result as abnormal, indicating that there is a problem with the device's response speed or startup mechanism.

[0078] For example, at the start of the test, a discharge instruction is sent to the charging and discharging equipment through the simulated vehicle system, requiring the equipment to start discharging at a power of 80kW. The test system then starts a timer, sets a preset duration of 5 seconds, and begins monitoring the response of the charging and discharging equipment. If the charging and discharging equipment starts to discharge continuously at a power of 80kW within 5 seconds, the test system will determine that the discharge time detection result is normal. On the contrary, if the charging and discharging equipment does not start discharging within 5 seconds, or if it starts but fails to continuously reach the specified power, the test system will determine that the discharge time detection result is abnormal.

[0079] This embodiment ensures the normal operation of the charging and discharging device and its normal response to instructions by sending a discharge instruction to the charging and discharging device and determining whether the charging and discharging device can respond and execute the operation within a preset time period, thereby ensuring the efficiency and reliability of the charging and discharging device and its interoperability with the vehicle.

[0080] Optionally, in the method for detecting the interoperability of charging and discharging devices provided in an embodiment of the present application, when the detection item is charge-discharge conversion, the performance of the charging and discharging devices is respectively tested according to the performance test process of M detection items, and M test results are obtained, including: sending a discharge instruction to the charging and discharging device through the vehicle system, and sending a charging instruction to the charging and discharging device when the charging and discharging device performs a discharge operation on the vehicle system; when the charging and discharging device converts from a discharge operation to a charging operation within a preset time, determining that there is no abnormality in the charge-discharge conversion; when the charging and discharging device does not convert from a discharge operation to a charging operation within the preset time, determining that the charge-discharge conversion is abnormal.

[0081] Specifically, charge-discharge conversion refers to the ability of a charging and discharging device to switch from discharge mode to charge mode. During charge-discharge conversion testing, the vehicle system sends a discharge command to the charging and discharging device, causing it to enter a discharge state to test whether its discharge function is functioning properly. While the charging and discharging device is in the discharge state, the vehicle system sends a charge command to the device, requesting it to immediately stop discharging and switch to charge mode. This tests whether the charging and discharging device can quickly and accurately switch from discharge mode to charge mode after receiving the charge command.

[0082] Furthermore, a preset duration can be set to monitor whether the charging and discharging device completes the transition from discharge to charge within that duration. If the charging and discharging device successfully transitions to charging mode within the preset duration and begins charging the electric vehicle, the test system will determine that there are no abnormalities in the charge-discharge transition, indicating that the device's conversion function is normal. If the charging and discharging device fails to complete the charge-discharge mode transition within the preset duration, the test system will determine that the charge-discharge transition is abnormal, indicating that there is a problem with the device's conversion mechanism or control logic.

[0083] For example, the charging and discharging device is in discharge mode, discharging from the electric vehicle to the power grid. The vehicle system simulated by the test system sends a command requesting the charging and discharging device to switch to charging mode and charge the electric vehicle. The test system then starts timing, setting a preset time of 3 seconds to observe the conversion speed of the charging and discharging device. If the charging and discharging device stops discharging within 3 seconds, switches to charging mode, and starts charging the electric vehicle, the test system will record the charge and discharge conversion result as normal. On the contrary, if the charging and discharging device fails to complete the conversion within 3 seconds, or fails to charge stably after conversion, the test system will record the charge and discharge conversion result as abnormal.

[0084] It should be noted that the charging and discharging sequence can also be adjusted to test the accuracy of the transition from the charging state to the discharging state.

[0085] This embodiment ensures the normal operation of the charging and discharging device and normal response to instructions by sending a switching instruction to the charging and discharging device and determining whether the charging and discharging device can respond and perform the operation within a preset time period, thereby ensuring the efficiency and reliability of the charging and discharging device and its interoperability with the vehicle.

[0086] Optionally, in the detection method for interoperability of charging and discharging equipment provided in an embodiment of the present application, when the detection item is on-grid switching, the performance of the charging and discharging equipment is tested separately according to the performance detection process of M detection items, and M detection results are obtained, including: setting the rated discharge active power of the charging and discharging equipment, and adjusting the charging and discharging equipment to operate under grid-connected operation conditions; sending an off-grid operation command to the charging and discharging equipment, and judging whether the charging and discharging equipment is switched to the off-grid operation mode; determining that the on-grid switching is abnormal if it is not switched to the off-grid operation mode; sending a grid-connected operation command to the charging and discharging equipment; determining that the on-grid switching is abnormal if it is not switched to the grid-connected operation mode; and determining that there is no abnormality in the on-grid switching if it is switched to the grid-connected operation mode.

[0087] Specifically, on-grid and off-grid switching refers to the ability of the charging and discharging equipment to switch between the two modes of grid connection (grid-connected) and independent operation (off-grid). In the case of on-grid and off-grid switching detection, the rated discharge active power of the charging and discharging equipment can be set to a predetermined value, such as 100kW. Then, the charging and discharging equipment is adjusted to the grid-connected operating condition, that is, the equipment is connected to the grid and is ready to start discharging according to the grid instruction, so as to ensure that the charging and discharging equipment is in a testable initial state for subsequent on-grid and off-grid switching detection.

[0088] Furthermore, when the charging and discharging device begins discharging, the test system can send an off-grid operation command to the charging and discharging device, instructing the device to switch from grid-connected mode to independent operation mode, no longer relying on grid instructions. Subsequently, the charging and discharging device is monitored to see whether it can correctly respond to the command, switch to off-grid operation mode, and continue discharging. This verifies whether the charging and discharging device can operate independently and maintain the predetermined discharge active power after receiving the off-grid command.

[0089] If the charging and discharging device fails to switch to off-grid mode after receiving the off-grid operation command, the test system records the off-grid switching result as abnormal, indicating that the device had a functional problem when switching to off-grid mode. After the charging and discharging device successfully switches to off-grid operation mode and discharges, the test system sends a grid-connected operation command to the device again, requiring the device to reconnect to the grid and operate according to the grid instructions. This further evaluates the charging and discharging device's ability to switch from off-grid mode back to grid-connected mode.

[0090] If the charging and discharging equipment fails to properly switch back to grid-connected mode after receiving the grid-connected operation command, the test system will also record the on-grid and off-grid switching result as abnormal, indicating that the equipment has a defect in grid-connected switching. If the charging and discharging equipment can successfully switch to grid-connected mode after receiving the grid-connected operation command and perform charging and discharging operations according to the grid instructions, the test system will record the on-grid and off-grid switching result as normal, indicating that the equipment's on-grid and off-grid switching function is normal.

[0091] For example, before the test begins, the rated discharge active power of the charging and discharging equipment is set to 100kW, and it is adjusted to the grid-connected operation condition, that is, the equipment is connected to the grid and is ready to start discharging according to the grid instructions. Subsequently, the test system sends an off-grid operation command, requiring the equipment to disconnect from the grid and operate independently. Assume that the equipment successfully switches to off-grid mode and maintains a discharge power of 100kW. After the equipment has been running independently for a period of time, the test system sends a grid-connected operation command to the equipment again, requiring the equipment to reconnect to the grid. If the charging and discharging equipment can smoothly switch back to the grid-connected operation mode and adjust the discharge power according to the grid instructions, for example, adjusting the discharge power to 80kW according to the grid load requirements, then the test system will determine that there is no abnormality in the on-grid and off-grid switching, and the on-grid and off-grid switching function of the equipment is normal.

[0092] This embodiment ensures that the charging and discharging equipment can accurately and reliably switch between the on-grid and off-grid modes by switching between the on-grid and off-grid modes, improves the flexibility and adaptability of the equipment, and ensures the interoperability between the charging and discharging equipment and the power grid.

[0093] Optionally, in the method for detecting the interoperability of charging and discharging devices provided in an embodiment of the present application, determining the interoperability detection result of the charging and discharging devices based on M detection results includes: when all M detection results are normal, determining that the interoperability detection result of the charging and discharging devices is normal; when any one of the M detection results is abnormal, determining that the interoperability detection result of the charging and discharging devices is abnormal.

[0094] Specifically, after completing the performance testing process for M specific test items, the collected M test results are analyzed and summarized to determine the overall interoperability performance of the charging and discharging equipment. If the charging and discharging equipment can meet the expected performance standards and functional requirements in all test items, its interoperability test results will be considered "qualified" or "passed", thus completing the complete process of determining the interoperability test results of the charging and discharging equipment based on the test results.

[0095] For example, after completing all test items, if the charging and discharging equipment does not show any abnormalities or failures in all 10 test items such as communication function and discharge control function, the test system will combine these test results and determine that the interoperability test result of the charging and discharging equipment is "qualified", indicating that it can safely interact with electric vehicles and the power grid for charging and discharging. If the charging and discharging equipment is found to have performance problems or insufficient functions in any test item, the test system will determine its interoperability test result as "unqualified", and the charging and discharging equipment needs to be improved or repaired before retesting, thereby avoiding operational failures of the charging and discharging equipment and ensuring that the charging and discharging equipment can operate normally.

[0096] This embodiment ensures that all key performances of the charging and discharging equipment meet standards in the interaction with the electric vehicle and the power grid by comprehensively analyzing M test results, thereby effectively evaluating the interoperability of the equipment.
