[0017] Figure 2 This is a schematic diagram of the structure of a charging pile fault safety testing system provided in an exemplary embodiment of this application.

[0018] Figure 3 This is a structural diagram of an electronic device provided in an exemplary embodiment of this application. Detailed Implementation

[0019] Hereinafter, exemplary embodiments according to this application will be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this application, and not all embodiments of this application. It should be understood that this application is not limited to the exemplary embodiments described herein.

[0020] Figure 1 This is a flowchart illustrating a fault safety testing method for charging piles provided in an exemplary embodiment of this application. Figure 1As shown, the fault safety testing method for this charging pile includes the following steps: Step 110: Obtain the vehicle charging parameters of the charging vehicle.

[0021] The charging pile fault safety testing method of this application is applied to a charging system, which includes a charging pile, a virtual charging system model, and a virtual vehicle model, wherein the charging pile, virtual charging system model, and virtual vehicle model are connected sequentially. The charging pile is used to output electrical energy, the virtual charging system model is used to simulate the charging strategy control of vehicle charging, and the virtual vehicle model is used to store vehicle charging parameters. The vehicle charging parameters include vehicle model, battery parameters, and communication protocol. This application connects the charging plug of the charging pile to the corresponding charging socket of the virtual simulation test platform to complete the physical connection of the equipment. By acquiring vehicle messages from various electric vehicles and interpreting the messages to convert them into vehicle charging parameter tables, these tables are stored in the database module of the virtual vehicle model to form a charging parameter library for the charging vehicles. During the test, by retrieving the corresponding vehicle charging parameter tables from the database module of the virtual vehicle model, a model is built using digital twin technology to reproduce the actual vehicle charging environment.

[0022] Step 120: Based on the vehicle charging parameters, determine the charging pile operating parameters during the charging process.

[0023] This application determines the charging needs of a vehicle based on its charging parameters, and then determines the charging pile's operating parameters based on those charging needs, in order to simulate charging the vehicle.

[0024] Step 130: Inject a test fault signal into the charging station.

[0025] The test fault signal represents a fault in the charging vehicle. This application achieves fault testing of the charging pile by injecting a test fault signal into the charging system. Specifically, the test fault signal can be injected into the charging vehicle or directly into the charging pile.

[0026] Step 140: Collect the feedback signal after the charging pile receives the test fault signal.

[0027] The feedback signal includes a notification signal or a response measure signal. This application, after injecting a test fault signal, collects the response signal or response measure of the charging pile to determine the charging pile's response information after receiving the test fault signal.

[0028] Step 150: Determine the fault safety level of the charging pile based on the feedback signal and the test fault signal.

[0029] Based on the feedback signal and the test fault signal, a comprehensive judgment is made on whether the feedback signal of the charging pile in response to the test fault signal can eliminate the test fault or reduce the impact of the test fault signal, thereby determining the fault safety level of the charging pile.

[0030] This application provides a charging pile fault safety testing method, which involves acquiring vehicle charging parameters, including vehicle model, battery parameters, and communication protocol; determining charging pile operating parameters during the charging process based on the vehicle charging parameters; injecting a test fault signal into the charging pile, wherein the test fault signal represents a fault in the charging vehicle; collecting feedback signals from the charging pile after receiving the test fault signal, wherein the feedback signals include notification signals or response measure signals; and determining the fault safety level of the charging pile based on the feedback signals and the test fault signal. By acquiring the vehicle charging parameters to determine the charging pile operating parameters, establishing a charging handshake based on the vehicle charging parameters and the charging pile operating parameters, and determining the fault safety level of the charging pile by injecting the test fault signal and collecting the feedback signals from the charging pile, this method tests the response measures of the charging pile to faults during the charging process, determines the charging pile's response measures to fault signals, and thus determines its safety level, thereby accurately obtaining the safety test results of the charging pile.

[0031] In one embodiment, step 120 can be implemented as follows: based on vehicle charging parameters, select a charging strategy suitable for the charging vehicle; based on the charging strategy, determine the charging pile operating parameters during the charging process.

[0032] The charging strategy includes charging handshake timing, charging power, and charging interface parameters. The charging parameters have a virtual adjustment function and can generate waveform strategies. Specifically, the AC-to-DC rectification process can use diodes and a single-phase path to convert the two positive and negative half-waves into two positive half-waves. This application selects a corresponding charging strategy based on the vehicle's charging parameters to perform the charging operation. Furthermore, based on this charging strategy, it determines the charging pile's operating parameters during the charging process, thereby determining the charging pile operating parameters that meet the vehicle's charging needs, thus achieving simulated charging matching between the charging pile and the virtual vehicle.

[0033] Optionally, after obtaining the charging pile's operating parameters, this application evaluates the charging strategy of the charging pile. If the evaluation result is qualified, the charging operation is performed based on the charging strategy and the corresponding charging pile operating parameters; otherwise, the charging strategy is switched until the evaluation result is qualified.

[0034] In one embodiment, the above-mentioned charging pile fault safety test method may further include: collecting the output information of the charging pile; correspondingly, the specific implementation of the above-mentioned step 130 may be: if the output information matches the charging pile operating parameters, then inject a test fault signal into the charging pile.

[0035] The test fault signals include, but are not limited to, power battery voltage fault signals, power battery current fault signals, power battery temperature fault signals, power battery insulation status signals, power battery output connector over-temperature fault signals, and BMS component / battery pack output connector over-temperature signals. This application collects the output information of the charging pile. If the output information matches the charging pile's operating parameters, i.e., if the output information matches the charging strategy, it indicates that the charging pile and vehicle are in a normal charging state. At this time, a test fault signal is injected into the charging pile to test its response performance.

[0036] In one embodiment, the specific implementation of step 140 above may be as follows: after injecting a test fault signal, periodically collect the output information of the charging pile; calculate the difference between the current output information collected in the current cycle and the historical output information collected in the previous cycle; if the difference is greater than a preset difference threshold, then collect a feedback signal.

[0037] After injecting a test fault signal, this application periodically collects the output information of the charging pile, and determines the feedback signal of the charging pile after receiving the test fault signal by calculating the difference between the current output information collected in the current cycle and the historical output information collected in the previous cycle. That is, if the difference between the current output information and the historical output information is greater than a preset difference threshold, it indicates that the charging pile has taken countermeasures under the action of the test fault signal, and its feedback signal is collected at this time.

[0038] In one embodiment, step 150 can be implemented by determining the fault safety level of the charging pile based on the safety handling measures corresponding to the feedback signal and the test fault signal.

[0039] For each test fault signal, there is a corresponding safety handling measure (i.e., standard safety handling measure). After collecting the feedback signal from the charging pile, this application determines the fault safety level of the charging pile based on the feedback signal and the safety handling measure.

[0040] In one embodiment, step 150 can be implemented as follows: if the feedback signal is a safety handling measure corresponding to a test fault signal, then the fault safety level of the charging pile is determined to be high.

[0041] If the feedback signal corresponds to a safety handling measure for a test fault signal, meaning the charging pile responds to the test fault signal using standard safety procedures, then the charging pile is safe in dealing with the test fault signal, and therefore its fault safety level can be determined to be high. Conversely, if the feedback signal does not correspond to a safety handling measure for a test fault signal, meaning the charging pile's response is not a standard safety procedure, then the charging pile is unsafe in dealing with the test fault signal, and therefore its fault safety level can be determined to be low.

[0042] In one embodiment, the safety handling measures corresponding to the test fault signal include multiple measures; wherein, the specific implementation of the above step 150 may be: if the feedback signal is the optimal handling measure among multiple safety handling measures, then the fault safety level of the charging pile is determined to be high.

[0043] There may be multiple safety measures for the same test fault. For example, when the power battery temperature fault occurs, the output current of the charging pile can be reduced, charging of the vehicle can be suspended until the temperature fault of the power battery disappears and then charging can be resumed, or charging of the vehicle can be stopped directly. This application can divide the safety measures into multiple levels according to the degree of impact. For example, the above-mentioned safety measures for handling power battery temperature faults can be divided into first-level measures (reducing the output current of the charging pile), second-level measures (suspending charging of the vehicle), and third-level measures (stopping charging of the vehicle directly) from low to high. If the feedback signal given during charging is the lowest level of measures (i.e., the optimal measures), then the fault safety level of the charging pile is determined to be high. If the charging pile adopts the highest level of measures, that is, stopping charging when a fault occurs, although it is safe, its charging effect is poor.

[0044] Optionally, if the feedback signal from the charging pile obtained during testing is not the optimal handling measure, this application can input the test fault signal and the corresponding optimal handling measure into the charging pile to optimize the fault response measures of the charging pile.

[0045] Optionally, when injecting a test fault signal, this application can dynamically adjust the intensity, frequency, and other information of the test fault signal to test the vehicle's dynamic response capability. Preferably, this application can input a dynamically changing test fault signal (i.e., a test fault signal curve) and collect the charging pile's response curve (i.e., a feedback signal curve). The safety performance of the charging pile is determined based on the changing trend between the test fault signal curve and the response curve. For example, the trend of the overall curves of the test fault signal curve and the response curve can be aligned. Specifically, multiple vertices of the overall curves of the test fault signal curve and the response curve are determined, and the alignment of the test fault signal curve and the overall curve of the response curve is achieved by using vertex alignment. After alignment, the response mutation value of the charging pile is determined by calculating the difference ratio between adjacent vertices (the ratio between the difference between adjacent vertices in the response curve and the difference between corresponding adjacent vertices in the test fault signal curve), thereby determining the response boundary value of the charging pile.

Figure 2 As shown, the charging pile fault safety testing system 20 includes: a charging parameter acquisition module 21, used to acquire the vehicle charging parameters of the charging vehicle; wherein, the vehicle charging parameters include vehicle model, battery parameters, and communication protocol; an operating parameter determination module 22, used to determine the charging pile operating parameters during the charging process based on the vehicle charging parameters; a test fault injection module 23, used to inject a test fault signal into the charging pile; wherein, the test fault signal is a signal representing a fault in the charging vehicle; a feedback signal acquisition module 24, used to acquire the feedback signal after the charging pile receives the test fault signal; wherein, the feedback signal includes a notification signal or a response measure signal; and a safety level determination module 25, used to determine the fault safety level of the charging pile based on the feedback signal and the test fault signal.

[0047] This application provides a charging pile fault safety testing system. The system acquires vehicle charging parameters (including vehicle model, battery parameters, and communication protocol) through a charging parameter acquisition module 21. An operating parameter determination module 22 determines the charging pile's operating parameters during the charging process based on these parameters. A test fault injection module 23 injects a test fault signal into the charging pile, where the test fault signal represents a fault in the charging vehicle. A feedback signal acquisition module 24 acquires the feedback signal received by the charging pile after receiving the test fault signal, where the feedback signal includes a notification signal or a response measure signal. A safety level determination module 25 determines the charging pile's fault safety level based on the feedback signal and the test fault signal. By acquiring the vehicle charging parameters, the system determines the charging pile's operating parameters, establishes a charging handshake based on these parameters, and determines the charging pile's fault safety level by injecting the test fault signal and acquiring the charging pile's feedback signal. This allows for testing the charging pile's response measures to faults during charging, determining the charging pile's response to fault signals, and thus determining its safety level, thereby accurately obtaining the charging pile's safety test results.

[0048] In one embodiment, the above-mentioned operating parameter determination module 22 can be further configured to: select a charging strategy suitable for the charging vehicle based on the vehicle charging parameters; and determine the charging pile operating parameters during the charging process based on the charging strategy.

[0049] In one embodiment, the above-mentioned charging pile fault safety test system 20 can be further configured to: collect the output information of the charging pile; correspondingly, the above-mentioned test fault injection module 23 can be further configured to: inject a test fault signal into the charging pile if the output information matches the charging pile operating parameters.

[0050] In one embodiment, the feedback signal acquisition module 24 can be further configured to: periodically acquire the output information of the charging pile after injecting a test fault signal; calculate the difference between the current output information acquired in the current cycle and the historical output information acquired in the previous cycle; and acquire a feedback signal if the difference is greater than a preset difference threshold.

[0051] In one embodiment, the safety level determination module 25 can be further configured to determine the fault safety level of the charging pile based on the safety handling measures corresponding to the feedback signal and the test fault signal.

[0052] In one embodiment, the safety level determination module 25 can be further configured to: if the feedback signal is a safety handling measure corresponding to a test fault signal, then determine that the fault safety level of the charging pile is high.

[0053] In one embodiment, the safety handling measures corresponding to the test fault signal include multiple measures; wherein, the safety level determination module 25 can be further configured to: if the feedback signal is the optimal handling measure among multiple safety handling measures, then determine the fault safety level of the charging pile as high.
