[0002] With the rapid and vigorous development of the new energy industry, charging piles, as an important infrastructure for electric vehicles, are increasingly widely used. The charging gun cable, a key component connecting the charging pile and the electric vehicle, may experience problems such as twisting, aging, wear, or poor contact during long-term use, leading to a decrease or abnormality in current transmission speed and affecting charging efficiency. Currently, while some testing equipment can test the charging gun cable, it primarily targets cables produced on the production line before they leave the factory, and cannot identify potential faults in the charging gun cable in real time during actual use of the charging pile. Summary of the Invention

[0003] This invention aims to at least partially solve one of the technical problems in related technologies. To this end, this invention proposes a method for judging charging gun cable faults in charging piles, an electronic device, and a storage medium, capable of judging and identifying possible faults in the charging gun cable during practical applications.

[0004] In a first aspect, embodiments of the present invention provide a method for determining charging gun line faults in charging piles, including:

[0006] The current transmission speed of the electrical pulse signal in the charging gun line is obtained, and the temperature change of the charging gun line during the transmission of the electrical pulse signal is obtained.

[0007] The fault condition of the charging gun cable is determined based on the current transmission speed and the temperature change.

[0008] Optionally, in one embodiment of the present invention, obtaining the temperature change of the charging gun wire during the transmission of the electrical pulse signal includes:

[0009] The charging gun wire is divided into multiple gun wire regions equally according to the preset temperature field length.

[0010] During the transmission of the electrical pulse signal, the temperature change value and temperature change rate of each gun line region are collected respectively.

[0011] Optionally, in one embodiment of the present invention, determining the fault status of the charging gun cable based on the current transmission rate and the temperature change includes:

[0012] When it is determined that the current transmission speed is greater than or equal to a preset current speed threshold, it is determined that the charging gun cable is fault-free.

[0013] Optionally, in one embodiment of the present invention, determining the fault status of the charging gun cable based on the current transmission rate and the temperature change includes:

[0014] When it is determined that the current transmission speed is less than the preset current speed threshold, based on the temperature change value and temperature change rate of each gun wire region, several gun wire regions are selected as temperature hotspot regions from all the gun wire regions.

[0015] The difference between the current velocity threshold and the current transmission velocity is obtained as a percentage relative to the current transmission velocity to obtain a difference parameter.

[0016] Based on the difference parameter and all the temperature hotspot areas, the fault condition of the charging gun cable is determined.

[0017] Optionally, in one embodiment of the present invention, determining the fault status of the charging cable based on the difference degree parameter combined with all the temperature hotspot areas includes:

[0018] When the difference degree parameter is less than or equal to a preset difference percentage threshold, determine whether the number of all the temperature hotspot areas is less than a preset temperature hotspot distribution threshold. If so, determine that the fault level of the charging gun cable is a level one fault; otherwise, determine that the fault level of the charging gun cable is a level two fault.

[0019] Optionally, in one embodiment of the present invention, determining the fault status of the charging cable based on the difference degree parameter combined with all the temperature hotspot areas includes:

[0020] When the difference degree parameter is greater than the preset difference percentage threshold, determine whether the temperature change value of any of the temperature hot spots exceeds the preset maximum area temperature change. If so, determine that the fault level of the charging gun cable is a level four fault; otherwise, proceed to the next step.

[0021] Determine whether the rate of temperature change in the corresponding temperature hotspot area is less than the preset maximum heating rate. If so, determine that the fault level of the charging gun line is a level three minor fault; otherwise, determine that the fault level of the charging gun line is a level three severe fault.

[0022] Optionally, in one embodiment of the present invention, obtaining the current transmission speed of the electrical pulse signal in the charging gun line includes:

[0023] Obtain the total transmission time of the electrical pulse signal in the charging gun line;

[0024] Given a fixed total length of the charging gun wire, the quotient of the total length and the total transmission time is calculated to obtain the current transmission speed of the electrical pulse signal in the charging gun wire.

[0025] In a second aspect, embodiments of the present invention provide an electronic device, comprising:

[0026] At least one processor;

[0027] At least one memory for storing at least one program;

[0028] When at least one of the programs is executed by at least one of the processors, the charging gun line fault judgment method of the charging pile as described in the first aspect is implemented.

[0029] Thirdly, embodiments of the present invention provide a computer-readable storage medium storing a processor-executable program, wherein the processor-executable program, when executed by a processor, is used to implement the charging gun line fault judgment method for charging piles as described in the first aspect.

[0030] The present invention proposes a method, electronic device, and storage medium for judging charging gun line faults in charging piles. It transmits a preset electrical pulse signal to the charging gun line to obtain the current transmission speed of the electrical pulse signal in the charging gun line. This current transmission speed serves as the basic parameter for fault judgment. Furthermore, considering the complementarity of the current transmission speed judgment, it also obtains the temperature change of the charging gun line during the transmission of the electrical pulse signal. Therefore, a dual-evidence judgment can be made based on both the current transmission speed and temperature change to quickly and accurately determine the fault condition of the charging gun line. Thus, it can effectively and reliably judge and identify potential faults in the charging gun line during practical applications, which is beneficial for further improving the stability of the charging gun line in use.

[0038] Figure 8 This is a schematic diagram of the structure of an electronic device provided in an embodiment of the present invention. Detailed Implementation

[0039] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0040] It should be noted that although functional modules are divided in the device schematic diagram and the logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than the module division in the device or the order in the flowchart.

[0041] Figure 1 This is a flowchart illustrating a method for determining charging gun cable faults in a charging pile according to an embodiment of the present invention. Figure 1 As shown, the method for determining the fault of the charging gun cable of the charging pile may include, but is not limited to, steps S1 to S3.

[0042] Step S1: Transmit a preset electrical pulse signal to the charging gun line. The preset electrical pulse signal may be set to have a specific frequency and amplitude. For example, a high-precision signal generator may be used to generate a stable electrical pulse signal to ensure the accuracy of the electrical pulse signal transmission.

[0043] Step S2: Obtain the current transmission speed of the electrical pulse signal in the charging gun line, and obtain the temperature change of the charging gun line during the transmission of the electrical pulse signal. The obtained current transmission speed and temperature change are used as historical detection records and can be stored in a pre-configured storage module for subsequent query and analysis. The storage module can be, but is not limited to, a large-capacity memory, such as flash memory or hard disk, to ensure long-term data preservation and secure storage.

[0044] Step S3: Determine the fault condition of the charging gun cable based on the current transmission speed and temperature changes.

[0045] In this step, a preset electrical pulse signal is emitted to the charging gun line to obtain the current transmission speed of the electrical pulse signal in the charging gun line. This current transmission speed serves as the basic parameter for fault diagnosis. Considering the complementarity of the current transmission speed criterion, the temperature change of the charging gun line during the transmission of the electrical pulse signal is also obtained. Thus, a dual-evidence judgment can be made based on the current transmission speed and temperature change to quickly and accurately determine the fault condition of the charging gun line. Therefore, it is possible to effectively and reliably identify and diagnose potential fault conditions of the charging gun line in practical applications, which is beneficial to further improving the stability of the charging gun line in use.

[0046] It should be noted that even if a charging pile may be equipped with multiple charging gun lines, the charging gun line fault judgment method provided in this embodiment of the invention is applicable to each charging gun line. Those skilled in the art can select the corresponding charging gun line for fault judgment test according to the actual application scenario. To avoid redundancy, each of the following embodiments is described using a single charging gun line as an example, and will not be elaborated further.

[0047] like Figure 2 As shown in one embodiment of the present invention, step S2, obtaining the current transmission speed of the electrical pulse signal in the charging gun line, may include, but is not limited to, the following steps:

[0048] Step S21: Obtain the total transmission time of the electrical pulse signal in the charging gun line;

[0049] Step S22: Given the total length of the charging gun wire, calculate the quotient of the total length and the total transmission time to obtain the current transmission speed of the electrical pulse signal in the charging gun wire.

[0050] In this step, by obtaining the total transmission time of the electrical pulse signal in the charging gun line and the total length of the charging gun line, the current transmission speed of the electrical pulse signal in the charging gun line can be reliably obtained by calculating the quotient of the total length and the total transmission time. This method is simple and fast, and allows those skilled in the art to understand the current transmission speed of the electrical pulse signal in the charging gun line in real time, so as to further track and evaluate the performance of the charging gun line.

[0051] In one embodiment, there are various ways to obtain the total transmission time of the electrical pulse signal in the charging gun line, and there is no limitation here. For example, but not limited to, an electrical pulse signal can be transmitted to one end of the charging gun line through a pre-configured signal transmitting module, and then the electrical pulse signal can be received from the other end of the charging gun line through a pre-configured signal receiving module. Thus, the total transmission time of the electrical pulse signal in the charging gun line can be determined based on the transmission time of the electrical pulse signal by the signal transmitting module and the reception time of the electrical pulse signal by the signal receiving module.

[0052] like Figure 3 As shown, in one embodiment of the present invention, step S2, which involves obtaining the temperature change of the charging gun cable during the transmission of the electrical pulse signal, may include, but is not limited to, the following steps:

[0053] Step S23: Divide the charging gun wire into multiple gun wire regions equally according to the preset temperature field length.

[0054] Step S24: During the transmission of the electrical pulse signal, the temperature change value and temperature change rate of each gun line area are collected. For example, but not limited to, this can be done by setting up corresponding temperature sensors in each gun line area to collect multiple sets of continuous temperature data according to the time length, thereby determining the temperature change value and temperature change rate of the corresponding gun line area based on this data.

[0055] In this step, the charging gun line is divided into multiple gun line regions according to a preset temperature field length to facilitate monitoring of the temperature field distribution along the entire length of the charging gun line, that is, to monitor the temperature changes in different regions of the charging gun line. Thus, during the transmission of the electrical pulse signal, the temperature change value and temperature change rate of each gun line region can be collected separately, thereby clarifying the overall temperature field distribution of the charging gun line.

[0056] In one embodiment, the specific temperature field length can be set according to the total length of the charging gun cable and the actual application scenario, and there is no limitation here.

[0057] In one embodiment, a temperature preprocessing function can also be configured, which automatically filters out minor numerical changes caused by ambient temperature fluctuations and retains only the effective temperature data, so as to obtain more accurate temperature change values ​​and temperature change rates in the gun line area with smaller errors.

[0058] like Figure 4 As shown, in one embodiment of the present invention, step S3 may include, but is not limited to, the following steps:

[0059] Step S31: When the current transmission speed is determined to be greater than or equal to the preset current speed threshold, the charging gun cable is determined to be fault-free.

[0060] In this step, if the current transmission speed is determined to be greater than or equal to the preset current speed threshold, it means that the current transmission speed in the charging gun cable has at least reached the expected level of the current speed threshold, and there is no situation such as the current transmission being too slow or stopping. Therefore, it can be determined that the charging gun cable is fault-free.

[0061] In one embodiment, the specific value of the current speed threshold can be selected and set according to the actual application scenario and the parameters and specifications of the charging gun cable being tested, and there is no limitation here.

[0062] like Figure 5 As shown, in one embodiment of the present invention, step S3 may include, but is not limited to, the following steps:

[0063] Step S32: When it is determined that the current transmission speed is less than the preset current speed threshold, based on the temperature change value and temperature change rate of each gun wire area, select a number of gun wire areas as temperature hot spots from all gun wire areas.

[0064] Step S33: Obtain the percentage of the difference between the current velocity threshold and the current transmission velocity relative to the current transmission velocity to obtain the difference parameter;

[0065] Step S34: Determine the fault status of the charging gun cable based on the difference parameters and all temperature hotspot areas.

[0066] In this step, when the current transmission speed is determined to be less than the preset current speed threshold, it is considered that fault assessment based solely on current transmission speed may not be accurate. For example, in some scenarios, the change in current transmission speed may not be obvious, but the charging gun line may have already experienced or be about to experience early faults such as local overheating (e.g., slight connector oxidation). By monitoring all charging gun line areas, several charging gun line areas are selected as temperature hotspot areas. Then, the fault judgment of the charging gun line is made in combination with the temperature hotspot areas. This complements the current transmission speed monitoring to a certain extent. In particular, the percentage of the difference between the current speed threshold and the current transmission speed relative to the current transmission speed is obtained to obtain the degree of difference parameter. Then, based on the degree of difference parameter and all temperature hotspot areas, the fault condition of the charging gun line can be determined more accurately and reliably.

[0067] It should be noted that the principle behind the formation of temperature hotspots is as follows: when current is transmitted in the charging gun cable, if there are internal damage, loose connectors, or partial short circuits in the charging gun cable, the resistance of the faulty area will increase significantly. According to Joule's law, this area will generate abnormal heat, causing the temperature to be higher than the normal area, thus forming a "temperature hotspot".

[0068] In one embodiment, the specific method for selecting several gunline regions as temperature hotspot regions from all gunline regions can be selected according to the actual application scenario. For example, it can be evaluated based on a preset temperature change base threshold (set to ambient temperature + 10℃) and a temperature change base rate threshold (set to 0.5℃ / min). The temperature change value and temperature change rate of each gunline region in real time are compared with the temperature change base threshold and the temperature change base rate threshold, respectively. If it is determined that the temperature change value is less than the temperature change base threshold and the temperature change rate is less than the temperature change base rate threshold, then the gunline region can be determined as a temperature hotspot region. Otherwise, if any one of the conditions is not met, then the gunline region is determined not to be a temperature hotspot region.

[0069] like Figure 6 As shown, in one embodiment of the present invention, step S34 may include, but is not limited to, the following steps:

[0070] Step S341: When the difference degree parameter is less than or equal to the preset difference percentage threshold, determine whether the number of all temperature hotspot areas is less than the preset temperature hotspot distribution threshold. If so, determine the fault level of the charging gun cable as a level one fault; otherwise, determine the fault level of the charging gun cable as a level two fault.

[0071] In this step, when the difference degree parameter is less than or equal to the preset difference percentage threshold (e.g., set to 5%), it indicates that the overall current transmission speed of the charging gun line has a slight deviation, but the deviation is not significant. Then, an auxiliary evaluation is performed by judging whether the number of all temperature hot spots is less than the preset temperature hot spot distribution threshold (e.g., set to 7). If it is less, it indicates that the current temperature hot spots are relatively few (ideally, there are no temperature hot spots). The fault level of the charging gun line can be judged as a level one fault, that is, the level with the lowest fault impact. Conversely, it indicates that the current temperature hot spots are on a large scale. Thus, the fault level of the charging gun line can be judged as a level two fault, that is, the level with the second lowest fault impact.

[0072] like Figure 7 As shown, in one embodiment of the present invention, step S34 may include, but is not limited to, the following steps:

[0073] Step S342: When the difference degree parameter is greater than the preset difference percentage threshold, determine whether the temperature change value of any temperature hot spot area exceeds the preset maximum area temperature change. If so, determine the fault level of the charging gun cable as a level four fault; otherwise, proceed to the next step.

[0074] Step S343: Determine whether the temperature change rate of the corresponding temperature hotspot area is less than the preset maximum heating rate. If so, determine the fault level of the charging gun cable as a level three minor fault; otherwise, determine the fault level of the charging gun cable as a level three severe fault.

[0075] In this step, if the difference parameter exceeds the preset difference percentage threshold, it indicates that the overall current transmission speed of the charging gun is relatively large. A more detailed assessment is needed to determine if the temperature change value of any hot spot area exceeds the expected target. Specifically, first, determine if the temperature change value of any hot spot area exceeds the preset maximum area temperature change (e.g., set to 20℃). If it does, it indicates that the temperature change values ​​of all hot spots are high, and the entire charging gun is operating under abnormal temperatures. In this case, the charging gun's fault level can be determined as Level 4, the highest level of fault impact. Conversely, if the temperature change values ​​of each hot spot area are within a slightly abnormal range, further analysis is needed to more accurately determine the charging gun's fault type. The system further determines whether the temperature change rate of the corresponding temperature hotspot area (i.e., the temperature hotspot area currently monitored in step S342) is less than the preset maximum heating rate (which can be set to 1℃ / min). If so, it indicates that the temperature change rate of the temperature hotspot area is at a low level, and the probability of potential faults in the charging gun line is significantly reduced. Thus, the fault level of the charging gun line in this case can be determined as a level three minor fault. Conversely, if the temperature change rate of the temperature hotspot area is at a relatively high level, the probability of potential faults in the charging gun line is significantly increased. In severe cases, it may even lead to the temperature approaching the insulation layer's tolerance limit. Thus, the fault level of the charging gun line in this case can be determined as a level three severe fault.
