[0048] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain the present application, rather than to limit the present application. For those skilled in the art, the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating the examples of the present application.

In addition, the character " / " in this article generally indicates that the associated objects before and after are a kind of "or" relationship.

[0050] Various abnormal conditions that may occur during the charging process of new energy vehicles, such as overheating of the charging station, will not only affect the charging efficiency, but may also cause damage to the electric vehicle itself and the charging facilities, and even cause safety accidents. When the charging station overheats, the abnormal situation needs to be accurately identified and handled to avoid potential risks. Most of the reasons for the overheating of the charging station are caused by excessive contact resistance of the product. There are many reasons for excessive contact resistance: loose plugs, oxidation of the contact surface, problems with the electronic lock of the charging socket, problems with the quality of the charging interface, etc.

[0051] According to statistics, most overheating of the charging seat during the charging process is related to the charging pile. Therefore, when the charging seat overheats during the charging process, it is necessary to accurately identify the status of the charging pile to quickly locate the risk source of overheating of the charging seat, and then handle the abnormal situation to avoid potential risks.

[0052] At present, in the prior art, when the charging base overheats during the charging process, the method for determining the status of the charging pile mainly relies on manual inspection, which consumes too much manpower, material resources and time. Therefore, the method for determining the status of the charging pile in the prior art has the problem of excessively high investment cost.

[0053] In order to solve the problems of the prior art, the embodiments of the present application provide a method, device, equipment, computer storage medium and computer program product for determining the status of a charging pile. The method for determining the status of a charging pile provided in the embodiments of the present application is first introduced below.

[0054] In order to facilitate the understanding of the embodiments of the present application, some professional terms that appear in the embodiments of the present application are first explained. The charging seat refers to the interface used by an electric vehicle (EV) or a plug-in hybrid electric vehicle (PHEV) to connect to an external power source for charging. The charging seat is a physical device installed on the vehicle to allow the vehicle to be connected to a charging pile or other type of power source via a cable to charge the vehicle's battery. The positive and negative terminals in the charging seat are the core components that realize the transfer of power from an external power source to an electric vehicle battery, and the charging seat temperature refers to the temperature of the positive / negative terminals of the charging seat.

[0055] Figure 1 FIG. 1 is a flow chart showing a method for determining the status of a charging pile provided by an embodiment of the present application. Figure 1 As shown, the method includes steps S110 to S130.

[0056] S110: Collecting data of the target vehicle charging at the first charging pile at the first moment, the data including the charging current and the temperature of the charging seat.

[0057] The big data platform can collect the vehicle charging data of a vehicle in real time when it is charging at a charging pile. The charging data can include different charging currents during the charging process and the corresponding charging seat temperature at different times under different charging currents, that is, the positive / negative terminal temperature of the charging seat. The charging data can also include information such as the charging and discharging status, the longitude and latitude of the vehicle, the charging pile number, and the charging pile logo.

[0058] S120: Based on the charging current and the temperature of the charging base, respectively calculate the temperature rise rate of the charging base under different charging current groups.

[0059] The charging current in the charging process can be grouped according to the charging current value range to obtain multiple charging current groups. For example, 50A can be divided into one group, and the charging current groups can include 101A-150A, 151A-200A, 201A-250A, etc.

[0060] Based on the temperature of the charging base corresponding to different times in each charging current group during the charging process, the temperature change range of the charging base corresponding to the next time period of each charging current group can be calculated, and then the temperature rise rate of the charging base in the next time period of each charging current group can be calculated respectively. The charging time of each charging current group during the charging process can be no less than 5 minutes.

[0061] Exemplarily, the temperature rise rate of the charging stand under different charging current groups can be calculated as shown in formula (1).

[0062]

[0063] Where, ΔT rate represents the temperature rise rate of the charging station under a target charging current group, Δt represents the time period, T t0+Δt Indicates the temperature of the charging station at time t0+Δt under the target charging current group, T t0 Indicates the temperature of the charging station at time t0 under the target charging current group. Exemplarily, the time period may be 2 minutes.

[0064] In one embodiment, a sliding window can be used to calculate the temperature rise rate of the charging seat in each small time interval within a longer time period under a target charging current group to obtain the temperature rise rates of multiple charging seats within a longer time period under the target charging current group, and then the maximum value ΔT of the temperature rise rates of multiple charging seats within a longer time period under the target charging current group is selected. rate_max As the charging seat temperature rise rate of the target charging current group. For example, the next longer time period of the target charging current group can be 2 minutes, that is, the sliding window is 2 minutes, and each smaller time interval in the next longer time period of the target charging current group is 1 second, that is, the sliding step is 1 second.

[0065] S130: Determine an identifier of the first charging pile according to the divided area information of the first charging pile.

[0066] The charging pile can be uniquely identified by dividing the area according to the location of the charging pile, and the unique identification of the charging pile can be determined. When the charging pile cannot upload the accurate number to the big data platform due to upgrades or other reasons, the unique identification can be determined by dividing the area according to the location of the charging pile. The location division area can refer to the longitude and latitude range of the area where the charging pile is located, and the location division area can be determined according to the longitude and latitude information of the vehicle charging at the charging pile.

[0067] S140: When the temperature rise rate of the charging base under the target charging current grouping is greater than the preset temperature rise rate and the abnormal charging pile list includes the identifier of the first charging pile, it is determined that the state of the first charging pile is abnormal and the target charging current grouping is any charging current grouping.

[0068] Determine whether the temperature rise rate of the charging seat under any charging current grouping is greater than the preset temperature rise rate threshold corresponding to the charging current grouping, and at the same time determine whether the charging pile identifier of the charging pile corresponding to the vehicle charging process is in the list of abnormal charging piles. When the temperature rise rate of the charging seat under any charging current grouping is greater than the preset temperature rise rate threshold corresponding to the charging current grouping, and the charging pile identifier of the charging pile corresponding to the vehicle charging process is in the list of abnormal charging piles, it is determined that the charging seat overheats during the charging process of the vehicle, and the charging pile corresponding to the vehicle charging process is an abnormal charging pile, that is, the overheating of the charging seat during the charging process of the vehicle is caused by the abnormality of the charging pile, and there is no need for technical personnel to manually check the overheating problem of the charging seat during the charging process of the vehicle.

[0069] Among them, the preset temperature rise rate threshold corresponding to each charging current group can be calculated by the charging seat temperature rise rate corresponding to each charging current group in the historical vehicle charging data, and is updated in real time according to the charging seat temperature rise rate corresponding to each charging current group in the historical vehicle charging data. The identification of all charging piles can be recorded through the charging pile list, and the charging pile list can include an abnormal charging pile list, and the abnormal charging pile list records the identification of charging piles in abnormal state. The abnormal charging pile list can be obtained by marking the identification of the charging pile in abnormal state in the charging pile list, and the abnormal charging pile list can be timely updated and maintained according to the status of the charging pile through the identification of the charging pile.

[0070] This embodiment first calculates the temperature rise rate of the charging seat under different charging current groups based on the collected charging current and temperature of the charging seat when the vehicle is charging at the charging pile, and determines the unique identification of the charging pile according to the area information of the charging pile, so as to provide an effective query basis for quickly and accurately determining the status of the charging pile, and also facilitates the rapid positioning and maintenance management of the charging pile. Then, when the temperature rise rate of the charging seat exceeds the corresponding preset temperature rise rate threshold under any charging current group, and the identification of the charging pile is included in the abnormal charging pile list, the status of the charging pile is determined to be abnormal, so that the source of the risk of overheating of the charging seat can be quickly and accurately located. Through automated data processing and analysis, the traditional manual inspection method is replaced, the dependence on manual professional skills and the required manpower and material resources for identifying the status of the charging pile is reduced, and the investment cost is reduced.

[0071] In a feasible embodiment, the method includes: when the temperature rise rate of the charging seat under the target charging current grouping is greater than the preset temperature rise rate, and the identification of the first charging pile is not included in the list of abnormal charging piles, obtaining the first target charging seat temperature rise rate under the target charging current grouping of the target vehicle during the charging process of the second charging pile, wherein the second moment is later than the first moment; when the temperature rise rate of the first target charging seat is less than or equal to the preset temperature rise rate, determining that the state of the first charging pile is abnormal.

[0072] Determine whether the temperature rise rate of the charging seat under any charging current grouping is greater than the preset temperature rise rate threshold corresponding to the charging current grouping, and at the same time determine whether the charging pile identifier of the charging pile corresponding to the vehicle charging process is in the abnormal charging pile list. When there is any charging current grouping where the temperature rise rate of the charging seat is greater than the preset temperature rise rate threshold corresponding to the charging current grouping, but the charging pile identifier of the charging pile corresponding to the vehicle charging process is not in the abnormal charging pile list, record the abnormal charging current grouping in which the temperature rise rate of the charging seat under the charging current grouping is greater than the preset temperature rise rate threshold corresponding to the charging current grouping.

[0073] Obtain the temperature rise rate of the charging seat under the abnormal charging current grouping during the charging process when the vehicle is charging at other charging piles at a certain moment in the future, and determine whether the temperature rise rate of the charging seat under the abnormal charging current grouping is greater than the preset temperature rise rate threshold corresponding to the abnormal charging current grouping. When the temperature rise rate of the charging seat under the abnormal charging current grouping is less than or equal to the preset temperature rise rate threshold corresponding to the abnormal charging current grouping, determine that the charging pile corresponding to the overheating of the charging seat during the charging process of the vehicle is an abnormal charging pile, that is, the overheating of the charging seat during the charging process of the vehicle is caused by the abnormality of the charging pile.

[0074] In one embodiment, when there is a charging seat temperature rise rate under any charging current grouping that is greater than the preset temperature rise rate threshold corresponding to the charging current grouping, but the charging pile identifier of the charging pile corresponding to the vehicle charging process is not in the abnormal charging pile list, and the maximum temperature of the charging pile corresponding to the vehicle charging process is within the limited temperature range, the limited temperature range may be less than 100 degrees, record the abnormal charging current grouping in which the charging seat temperature rise rate under the charging current grouping is greater than the preset temperature rise rate threshold corresponding to the charging current grouping, obtain the charging seat temperature rise rate under the abnormal charging current grouping during the charging process when the vehicle is charging at other charging piles at a certain moment thereafter, and continue to judge the status of the charging pile corresponding to the vehicle charging process.

[0075] In one embodiment, when judging whether the temperature rise rate of the charging seat under any charging current group in the vehicle charging data is greater than the preset temperature rise rate threshold corresponding to the charging current group, when there is a case where the temperature rise rate of the charging seat under any charging current group is greater than the preset temperature rise rate threshold corresponding to the charging current group, the charging pile corresponding to the vehicle charging process is suspected to be abnormal, and the identification of the charging pile can be recorded in the abnormal list as a first-level abnormality. When the charging pile identification of the charging pile corresponding to the vehicle charging process is not in the abnormal charging pile list, and then the charging data of the vehicle at a certain moment in the future when charging at other charging piles is finally determined to be abnormal, the charging pile identification of the charging pile can be recorded in the abnormal list as a second-level abnormality. Among them, in the implementation of this application, each time the charging pile identification of the charging pile corresponding to the vehicle charging process is judged whether it is in the abnormal charging pile list, it can be judged whether the charging pile identification of the charging pile corresponding to the vehicle charging process is recorded as a second-level abnormality in the abnormal charging pile list.

[0076] In one embodiment, the big data platform records all vehicle charging records, which include unique identification information of the charging pile, charging vehicle identification number (VIN), temperature rise abnormality flag, temperature rise abnormal current grouping, charging time, current grouping and abnormality level, etc. The temperature rise abnormality flag refers to the situation where the temperature rise rate of the charging seat of a certain charging current grouping is greater than the corresponding preset temperature rise rate threshold. The temperature rise abnormal current grouping refers to the specific charging current grouping where the temperature rise rate of the charging seat of the charging current grouping is greater than the corresponding preset temperature rise rate threshold.

[0077] The big data platform extracts the following charging records from the vehicle charging records of the previous day at regular intervals every day to determine the status of the charging pile, including charging records with abnormal charging seat temperature rise rate, charging records of abnormal charging piles in the abnormal charging pile list, and charging records of vehicles in the charging vehicle list with abnormal charging seat temperature rise rate. Among them, the charging record with abnormal charging seat temperature rise rate includes the unique identification information of the charging pile, the charging vehicle identification number VIN, the temperature rise abnormality mark, the temperature rise abnormal current grouping, the charging time, the current grouping and the abnormality level. The charging record of the abnormal charging pile in the abnormal charging pile list includes the unique identification of the charging pile, the vehicle VIN, the charging time, the current grouping, the abnormality level, etc. The charging record of the vehicle in the charging vehicle list with abnormal charging seat temperature rise rate includes the vehicle VIN, the charging time, the unique identification of the charging pile, the current grouping, and the abnormality level.

[0078] For example, Table 1 shows an embodiment of a method for determining the status of a charging pile. As shown in Table 1, at time T0, i.e., 2024-09-01, when the vehicle VIN1 is charging with the charging pile AA, an abnormal charging seat temperature rise rate occurs when the charging current is grouped as 200-250A, then the AA charging pile is added to the abnormal charging pile list, with an abnormal level of one, and the vehicle VIN1 is added to the abnormal vehicle list, with an abnormal level of one.

[0079] If the temperature rise rate of the charging seat is abnormal when the vehicle VIN1 is charged with charging pile AA and the charging current is grouped as 200-250A, the unique identification of the charging pile is determined and the list of abnormal charging piles is associated. The unique identification of the AA charging pile is already in the list of abnormal charging piles and the abnormality level is level 2. Then the abnormal temperature rise rate of the charging seat is classified as caused by the charging pile, and the technicians will no longer need to manually check and confirm this abnormality.

[0080] If the temperature rise rate of the charging seat is abnormal when the charging current is grouped between 200-250A while the vehicle VIN1 is being charged with the charging pile AA, determine the unique identifier of the charging pile and associate it with the list of abnormal charging piles. The unique identifier of the AA charging pile is not in the list of abnormal charging piles. The status of the charging pile is further determined by determining whether an abnormal charging temperature rise rate occurs when the charging current is grouped between 200-250A while the vehicle VIN1 is being charged with the charging pile AB at time T1.

[0081] At time T1, i.e. 2024-09-02, when the vehicle VIN1 is charging with charging pile AB, the charging temperature rise rate abnormality does not occur under the charging current group 200-250A, then the AA charging pile is added to the abnormal charging pile list, the abnormality level is level 2, and the AA charging pile is determined to be an abnormal pile. The abnormal temperature rise rate of the charging seat at time T0 is classified as caused by the charging pile, and the technicians will no longer conduct manual inspection and confirmation of this abnormality.

[0082] At time T2, that is, 2024-09-10, when vehicle VIN2 or vehicle VIN1 is charging with charging pile AA, if no abnormal charging temperature rise rate occurs under the charging current grouping 200-250A, the AA charging pile is judged as a normal pile, and the logo of the AA charging pile is deleted from the abnormal charging pile list. The vehicle is judged as an abnormal vehicle, and after secondary confirmation by the after-sales technician, the user can be invited to the store for inspection.

[0083]

[0084] Table 1

[0085] This embodiment compares the temperature rise rates of different charging piles at different time points and in the same charging current grouping, and judges the status of the charging pile in combination with a preset temperature rise rate threshold. It can more accurately determine whether the charging base is overheated due to the charging pile, which helps to reduce misjudgment. Compared with traditional manual inspection methods, this method uses automated data collection and analysis technology, and can complete the evaluation of a large number of charging pile status in a short time, thereby improving processing efficiency and reducing maintenance costs.

[0086] In an achievable implementation, after determining that the state of the first charging pile is abnormal, the method further includes: recording an identifier of the first charging pile in a list of abnormal charging piles.

[0087] After determining that the overheating of the charging base during the vehicle charging process is caused by an abnormal charging pile, an identifier of the charging pile is recorded in the abnormal charging pile list.

[0088] In one embodiment, after determining that the overheating of the charging base during the vehicle charging process is caused by an abnormal charging pile, the abnormal level of the identification of the charging pile is recorded as a level 2 abnormality in the abnormal charging pile list.

[0089] This embodiment records the identification of the abnormal charging pile in the abnormal list so that the charging pile status can be quickly determined by querying the table when the temperature rise of the charging seat is abnormal. The charging pile status can be determined quickly and effectively, thereby improving the efficiency of determining the charging pile status.

[0090] Figure 2 FIG. 1 is a flow chart of a method for determining a preset temperature rise rate threshold provided by an embodiment of the present application. In an achievable implementation, as Figure 2 As shown, when the temperature rise rate of the charging seat under the target charging current grouping is greater than the preset temperature rise rate, and the list of abnormal charging piles includes the identifier of the first charging pile, before determining that the state of the first charging pile is abnormal, the method also includes steps S210 to S230.

[0091] S210: Obtain historical charging seat temperature information under the target charging current group in the historical vehicle charging data.

[0092] The historical charging data can be obtained through the big data platform. The historical charging data may include the temperature of the charging station corresponding to different times in each charging current group during each charging process.

[0093] S220: Determine a historical charging seat temperature rise rate according to historical charging seat temperature information.

[0094] The temperature rise rate of the charging seat in the next time period of each charging current group in each charging process is calculated respectively, and the calculation process is shown in formula (1). Among them, the temperature rise rate of the charging seat in each smaller time interval in the next longer time period of each charging current group in each charging process can be calculated by using a sliding window to obtain multiple temperature rise rates of the charging seat in the next longer time period of each charging current group in each charging process, and then the maximum value ΔT_(rate_max) of the temperature rise rates of the multiple charging seats in the next longer time period of each charging current group in each charging process is selected as the temperature rise rate of the charging seat for each charging current group in each charging process.

[0095] S230: Determine a preset temperature rise rate according to the historical temperature rise rate of the charging base.

[0096] Based on the maximum value ΔT_(rate_max) of the charging seat temperature rise rate of each charging current grouping during multiple charging processes in the historical charging data, the set of maximum value ΔT_(rate_max) of the charging seat temperature rise rate of each charging current grouping can be used to calculate the preset charging seat temperature rise rate threshold parameter for each charging current grouping.

[0097] This embodiment sets the preset temperature rise rate based on historical data, so that the threshold is closer to the actual situation, reduces the risk of misjudgment due to fixed thresholds, improves the accuracy of identifying abnormal conditions, and can take into account the impact of factors such as different application scenarios on temperature rise, so that the preset temperature rise rate has better adaptability and flexibility. The preset temperature rise rate can also be continuously updated according to the latest historical data, which helps to improve the reliability of abnormal judgment of charging piles.

[0098] In one feasible implementation, step S230: determining a preset temperature rise rate based on the historical temperature rise rate of the charging seat, including: determining the upper quartile and lower quartile corresponding to the historical temperature rise rate of the charging seat based on the historical temperature rise rate of the charging seat; determining the preset temperature rise rate based on the upper quartile, the lower quartile and the preset coefficient.

[0099] According to the maximum value ΔT_(rate_max) of the charging seat temperature rise rate of each charging current group, the lower quartile and upper quartile of the maximum value ΔT_(rate_max) of the charging seat temperature rise rate of each charging current group are calculated, and the preset charging seat temperature rise rate threshold parameter of each charging current group is obtained by weighted summation of the difference between the upper quartile and the upper quartile and the upper quartile. The specific calculation process is shown in formula (2).

[0100] ΔT rate_threshold =Q3+k*(Q3-Q1)(2)

[0101] Where, ΔT rate_thresholdIt represents the preset temperature rise rate threshold of the charging current grouping, Q1 represents the lower quartile of the maximum value ΔT_(rate_max) of the charging seat temperature rise rate of the charging current grouping, Q3 represents the upper quartile of the maximum value ΔT_(rate_max) of the charging seat temperature rise rate of the charging current grouping, and k represents the coefficient, which can be adjusted according to actual conditions.

[0102] The big data platform calculates the maximum temperature rise rate ΔT of the positive / negative terminals of the charging station under different current groups in the vehicle charging data in real time rate_max * and compared with the temperature rise rate threshold of the same current group calculated last week. If ΔT rate_max * >ΔT rate_threshold , it will mark the temperature rise rate of the charging seat of the vehicle as abnormal during the charging process, and record the vehicle position, charging pile number and charging seat number.

[0103] This embodiment sets the preset temperature rise rate based on the statistical characteristics of the historical charging seat temperature rise rate, so that the threshold value is more in line with the actual operating conditions, avoiding the deviation that may be caused by artificially setting a fixed threshold value, using quartiles as reference points, and combining with preset coefficients to adjust the preset temperature rise rate, so that the method can adapt to changes under different environmental conditions and enhance the reliability of detecting abnormal conditions of the charging pile.

[0105]

[0106]

[0107] In one feasible implementation, before step S130: determining the identification of the first charging pile according to the divided area information of the first charging pile, the method includes: obtaining the position information of the vehicle charging at the first charging pile and the parking space number corresponding to the first charging pile; determining the divided area information of the first charging pile according to the position information; step S130: determining the identification of the first charging pile according to the divided area information of the first charging pile, including: determining the identification of the first charging pile according to the divided area information of the first charging pile and the parking space number corresponding to the first charging pile.

[0108] like Figure 3 As shown, a method for determining a unique identifier of a charging pile according to location information of a vehicle charging the charging pile and a parking space number corresponding to the charging pile is shown, and the method includes steps S310 to S330.

[0109] S310: Obtaining the location information of the vehicle charging at the first charging pile and the parking space number corresponding to the first charging pile.

[0110] As shown in Table 2, if the charging pile does not accurately upload the charging pile coding information, or the coded charging pile is accurately uploaded due to program upgrades, etc., the location information of the vehicle charging at the charging pile and the parking space number corresponding to the charging pile are obtained. The location information of the charging vehicle may include longitude and latitude, where the longitude and latitude are rounded to two decimal places. The parking space number corresponding to the charging pile can be uploaded by the vehicle automatic parking system.

[0111] S320: Determine the area division information of the first charging pile according to the location information.

[0112] As shown in Table 2, according to the longitude and latitude rounded to two decimal places, the longitude value ±0.001 degrees and the latitude value ±0.001 degrees are used as the charging pile location division area.

[0113] S330: Determine an identifier of the first charging pile according to the divided area information of the first charging pile and the parking space number corresponding to the first charging pile.

[0114] When the charging pile cannot upload the accurate number to the big data platform due to reasons such as upgrading, the unique identification can be determined by using the charging pile location division area and the parking space number corresponding to the charging pile, wherein the location division area can refer to the latitude and longitude range of the area where the charging pile is located, and the location division area can be determined based on the latitude and longitude information of the vehicle charging at the charging pile; the parking space number corresponding to the charging pile can be obtained by identifying it through an image recognition system such as a camera of a vehicle charging at the charging pile. For example, it can be identified by a vehicle-mounted camera when a vehicle charging at the charging pile is parked. As shown in Table 2, the charging pile can be uniquely identified according to the charging pile location division area and the parking space number corresponding to the charging pile, and the unique identification of the charging pile can be determined. When the charging pile cannot upload the accurate number to the big data platform due to reasons such as upgrading, the unique identification can be determined by using the location information of the vehicle charging at the charging pile and the number of the charging pile.

[0115] This embodiment can more accurately identify the specific charging pile where the problem occurs by combining the vehicle location information with the parking space number corresponding to the charging pile to further confirm the location division area and generate a unique identifier for the charging pile without obtaining the accurate number of the charging pile. After determining the unique identifier of the charging pile, the charging pile can be located more quickly and accurately, facilitating the management and maintenance of the charging pile.

[0116] Figure 4 A flow chart of a method for updating a charging pile list provided in one embodiment of the present application is shown.

[0117] The big data platform can receive and collect newly uploaded charging column numbers in real time. These numbers may come from newly installed charging piles or previously installed charging piles that failed to upload numbers accurately. The installed charging piles that failed to upload numbers accurately can be upgraded through OTA upgrades and other methods to accurately upload their charging pile codes. When these numbers come from previously installed charging piles that failed to upload numbers accurately, the installed charging piles that failed to upload numbers accurately may already include an identifier generated by dividing the area information according to the latitude and longitude of the charging pile and the parking space number corresponding to the charging pile. The identifier of the charging pile is recorded in the charging pile list. If the charging pile was previously determined to be an abnormal charging pile, then the identifier of the charging pile already exists in the abnormal charging pile list in the charging pile list.

[0118] At this time, after receiving the number accurately uploaded by the charging pile, the newly uploaded code can also be used as the identification of the charging pile, so that the charging pile has two corresponding identifications. Among them, the identification generated according to the latitude and longitude division area information of the charging pile and the parking space number corresponding to the charging pile is determined when the charging pile fails to accurately upload the number, and can be regarded as a temporary identification. In addition, the parking space number corresponding to the charging pile needs to be identified by the image recognition system such as the camera of the charging vehicle, and there may be a problem of insufficient recognition accuracy. Therefore, when the charging pile accurately uploads the number, the charging pile number can be used as an identification, and the temporary identification of the charging pile is replaced with the identification in the charging pile list. The updated identification of the charging pile continues to be used to judge the status of the charging pile, which can reduce the risk of inaccurate parking space number identification leading to inaccurate judgment of the charging pile status when the status of the charging pile is judged each time by the latitude and longitude division area information of the charging pile and the temporary identification generated by the parking space number corresponding to the charging pile.

[0119] In an achievable implementation, the method further includes updating the list of charging piles. The specific method for updating the list of charging piles is as follows: Figure 4 As shown, the method includes steps S410 to S450.

[0120] S410: Obtain the target number and target division area information of the target charging pile.

[0121] The target charging pile can be any charging pile, which can be a newly installed charging pile or a previously installed charging pile. The charging column number of the target charging pile and the area division information of the target charging pile, that is, the longitude and latitude division area, can be obtained through the big data platform. The longitude and latitude division area determination process is as follows: Figure 3 The processes from S310 to S320 are the same and will not be repeated here.

[0122] S420: When the preset correspondence between the divided area information and the identifier includes at least one identifier corresponding to the target divided area information, obtain the target parking space number corresponding to the target charging pile, wherein the correspondence between the divided area information and the identifier is generated according to the divided area information and the identifier determined based on the divided area information and the parking space number.

[0123] When generating a temporary identification of a charging pile through the latitude and longitude division area information of the charging pile and the parking space number corresponding to the charging pile, each charging pile and the temporary identification will correspond to a latitude and longitude division area information. Using a latitude and longitude division area information, the temporary identification of the charging pile in the latitude and longitude area corresponding to the latitude and longitude division area information can be generated multiple times. Then, a latitude and longitude division area information can have multiple corresponding temporary identifications, that is, how many charging piles with temporary identifications there are in the latitude and longitude area corresponding to the latitude and longitude division area information. Based on each latitude and longitude division area information and its corresponding temporary identification, a correspondence between the latitude and longitude division area information and the temporary identification can be established.

[0124] Through the established correspondence between the latitude and longitude division area information and the temporary identification, determine whether the latitude and longitude division area information of the target charging pile corresponds to the temporary identification. If so, it proves that there is a charging pile with a temporary identification in the latitude and longitude division area of ​​the target charging pile. The target charging pile may already have a temporary identification. At this time, the corresponding parking space number of the target charging pile is obtained. The parking space number corresponding to the target charging pile can be uploaded through the vehicle automatic parking system.

[0125] S430: Determine the identification of the target charging pile according to the target division area information and the target parking space number.

[0126] In order to further determine whether the charging pile with a temporary mark in the latitude and longitude division area of ​​the target charging pile is the target charging pile, the temporary mark of the target charging pile is determined according to the latitude and longitude division area information of the target charging pile and the parking space number corresponding to the target charging pile.

[0127] S440: When at least one identifier corresponding to the target division area information includes the identifier of the target charging pile, and the charging pile list includes the identifier of the target charging pile, determine the target identifier of the target charging pile according to the target division area information and the target number.

[0128] According to the temporary identification of the target charging pile, determine whether the temporary identification corresponding to the latitude and longitude division area information of the target charging pile includes the temporary identification of the target charging pile. If so, it proves that the target charging pile already has a temporary identification. Then determine whether the temporary identification of the target charging pile already exists in the charging pile list. If so, it is necessary to replace the temporary identification of the charging pile in the charging pile list with the number of the target charging pile as the identification.

[0129] Furthermore, in order to improve the uniqueness of the target charging pile identification, the target identification of the target charging pile can be generated by dividing the area information of the target charging pile by its latitude and longitude and the number of the target charging pile. The specific generation process is as follows:

[0130] As shown in Table 2, the location information of the vehicle charging at the target charging pile and the number of the target charging pile are obtained. The location information of the charging vehicle may include longitude and latitude, wherein the longitude and latitude are rounded to two decimal places. The number of the target charging pile can be uploaded through the charging pile. According to the longitude and latitude rounded to two decimal places, the longitude value is rounded to ±0.001 degrees and the latitude value is rounded to ±0.001 degrees as the target charging pile location to divide the area. The charging pile can be uniquely identified according to the location of the target charging pile and the charging pile number, and the unique identification of the charging pile can be determined. The charging pile numbers of different brands and platforms have their own numbers, and there is no unified rule for identification. Using the original number of the charging pile as an identification may result in duplication of the charging pile identification and non-unique charging pile identification. The location information of the charging pile charging vehicle and the number of the charging pile can be used to determine the unique identification.

[0131] S450: Update the identifier of the target charging pile in the charging pile list to the target identifier.

[0132] In the charging pile list, the target identifier is generated by dividing the area information by longitude and latitude and the number of the target charging pile to replace the temporary identifier of the target charging pile. The data corresponding to the number of the target charging pile and the temporary identifier of the target charging pile can also be merged and processed.

[0133] This embodiment obtains the newly uploaded number and division area of ​​any charging pile to ensure that all charging piles that may have temporary identifications will be analyzed and processed. By using the division area of ​​the charging pile to perform preliminary screening in the preset corresponding relationship between the division area and the temporary identification, it is preliminarily determined whether the charging pile belongs to the charging pile with a temporary identification, which can quickly narrow the scope, reduce unnecessary computing resource consumption, and focus on a specific area, thereby reducing the processing complexity of the entire system. On the basis of the preliminary screening, a more detailed match is performed based on the temporary identification of the charging pile, ensuring the accuracy of the identification of the charging pile, avoiding the problem that multiple charging piles in the same area are mistaken for the same, and improving the reliability and accuracy of the system. Once it is found that the target charging pile already has a temporary identification and the identification exists in the charging pile list, a unique identification is generated using the newly uploaded number and division area as a new identification for replacement. The introduction of the new identification enhances the uniqueness of each charging pile identification and reduces the risk caused by inaccurate parking space number identification. Ensuring that the latest and most accurate information is recorded in the charging pile list helps maintenance personnel to deal with problems in a timely and effective manner, simplifies the management and monitoring process of the charging pile, makes the system easier to maintain, and improves operational efficiency and the efficiency and reliability of charging pile status judgment.

[0134] In a feasible embodiment, the method also includes: obtaining the temperature rise rate of the second target charging seat under the target charging current grouping during the charging process of the first charging pile at a third moment, wherein the third moment is later than the first moment; when the temperature rise rate of the second target charging seat is less than or equal to the preset temperature rise rate, determining that the status of the first charging pile is normal; and deleting the identifier of the first charging pile from the list of abnormal charging piles.

[0135] Obtain the charging seat temperature rise rate of the charging pile with abnormal charging seat temperature rise rate during the charging process when charging other vehicles at a certain time later, and determine whether the charging seat temperature rise rate under the abnormal charging current grouping is greater than the preset temperature rise rate threshold corresponding to the abnormal charging current grouping. If the charging seat temperature rise rate under the abnormal charging current grouping is less than or equal to the preset temperature rise rate threshold corresponding to the abnormal charging current grouping, determine that the status of the charging pile with abnormal charging seat temperature rise rate during the charging process is normal, and delete the identification of the charging pile from the abnormal charging pile list. When the charging pile that has not accurately uploaded the code lacks a unique identification due to program upgrades and other reasons, the platform determines the unique identification of the charging pile based on the parking space number uploaded by automatic parking and the charging pile location area division to update and maintain the abnormal charging pile list.

[0136] Exemplarily, as shown in Table 1, at time T2, that is, 2024-09-10, when vehicle VIN2 or vehicle VIN1 is charged with charging pile AA, no abnormal charging temperature rise rate occurs under the charging current grouping 200-250A, then the AA charging pile is judged as a normal pile, the identification of the AA charging pile is deleted from the abnormal charging pile list, and the vehicle is judged as an abnormal vehicle. After secondary confirmation by the after-sales technician, the user can be invited to the store for inspection.

[0137] This embodiment confirms whether the charging pile has returned to normal by subsequently monitoring whether the charging seat overheats abnormally when the charging pile is charging, avoiding misjudgment caused by short-term fluctuations or other non-permanent factors, and ensuring the accuracy of the judgment of the charging pile status. When continuous monitoring shows that the charging pile has returned to normal, it is removed from the abnormal list, allowing flexible adjustment according to actual operating conditions, realizing a dynamic management mechanism, and facilitating the continuity and efficiency of the method for determining the status of the charging pile.

[0138] Based on the same concept, the embodiment of the present application provides a device for determining the status of a charging pile. Figure 5 The device for determining the status of a charging pile provided in an embodiment of the present application is described in detail.

[0148] In one embodiment, the acquisition module 510 is also used to obtain the target number and target division area information of the target charging pile; when the preset correspondence between the division area information and the identifier includes at least one identifier corresponding to the target division area information, obtain the target parking space number corresponding to the target charging pile, wherein the correspondence between the division area information and the identifier is generated according to the division area information, and the identifier determined based on the division area information and the parking space number; determine the identifier of the target charging pile according to the target division area information and the target parking space number; when at least one identifier corresponding to the target division area information includes the identifier of the target charging pile, and the identifier of the target charging pile is included in the charging pile list, determine the target identifier of the target charging pile according to the target division area information and the target number; and update the identifier of the target charging pile in the charging pile list to the target identifier.

[0149] In one embodiment, the acquisition module 510 is also used to obtain the temperature rise rate of the second target charging seat under the target charging current grouping during the charging process of the first charging pile at a third moment, wherein the third moment is later than the first moment; when the temperature rise rate of the second target charging seat is less than or equal to the preset temperature rise rate, it is determined that the status of the first charging pile is normal; and the identifier of the first charging pile is deleted from the list of abnormal charging piles.
