Description

Technical Field

[0001] This invention relates to the field of new energy vehicle charging technology, and more specifically, to a charging pile identification method and device. Background Technology

[0002] With the increasing popularity of electric vehicles globally, the construction of charging infrastructure and charging speed have gradually become focal points. Currently, most electric vehicles use AC charging stations, which are relatively slow, typically requiring several hours to fully charge. This process not only affects the user's charging experience but also limits the convenience of using electric vehicles. To improve charging efficiency, multi-gun charging technology has emerged. Multi-gun charging systems allow multiple charging points to be used simultaneously for a single electric vehicle. This technology not only shortens charging time but also improves the utilization rate of charging stations, given limited charging station resources, thereby enhancing the overall efficiency of the charging network.

[0003] However, not all existing charging piles support multi-gun charging in parallel. Maintenance personnel need to conduct on-site testing and identification to identify charging piles that support multi-gun charging in parallel, which results in high maintenance costs. Summary of the Invention

[0004] In view of this, embodiments of the present invention provide a charging pile identification method and apparatus, which automatically identifies and classifies whether the charging pile to be identified supports multi-gun parallel charging based on the charging message reported by the charging pile to be identified, eliminating the need for maintenance personnel to conduct on-site inspection and identification, and reducing identification costs.

[0006] Obtain the charging messages reported by the charging pile to be identified according to a preset time period, wherein the charging messages include the multi-gun parallel charging self-test results of the charging pile to be identified;

[0007] In response to the self-test result of the multi-gun parallel charging being pending verification, the corresponding charging message is stored in the pending verification message queue corresponding to the charging pile to be identified.

[0008] In response to the fact that the number of charging messages in the message queue to be reviewed is greater than the preset number of messages, the target charging order corresponding to the message queue to be reviewed is determined;

Based on the multi-gun parallel charging self-test result, a corresponding charging message is generated and the charging message is reported to the server.

[0024] The server is configured to receive the charging message, and in response to the multi-gun charging self-test result being pending verification, store the corresponding charging message in the pending verification message queue corresponding to the charging pile to be identified. In response to the number of charging messages in the pending verification message queue being greater than a preset number of messages, determine the target charging order corresponding to the pending verification message queue, determine the average current value of the target charging order, and in response to the average current value being greater than a preset current value, determine that the target charging order is a multi-gun charging order, update the number of multi-gun charging orders corresponding to the charging pile to be identified, and in response to the number of multi-gun charging orders being greater than a preset number of orders, determine that the identification result of the charging pile to be identified is that it supports multi-gun charging, where multi-gun charging means that the corresponding charging pile supports multiple charging guns charging the same car. In response to receiving a charging query page retrieval request sent by a user terminal, send a charging query page containing a charging map to the user terminal.

[0028] The message storage module is used to store the corresponding charging message in the message queue to be verified corresponding to the charging pile to be identified when the self-test result of the multi-gun parallel charging is to be verified.

[0034] Sixthly, a charging pile identification device is provided, applicable to charging piles to be identified, the device comprising:

[0042] The second display module is used to display a charging query page returned by the server, which includes a charging map. The charging map displays the identification results of charging piles that support multi-gun charging in parallel with specific icons. The identification results are determined based on whether the charging order corresponding to the charging pile to be identified is a multi-gun charging order. The multi-gun charging order is determined based on the multi-gun charging self-inspection results reported by the charging pile to be identified.

[0043] Eighthly, an electronic device is provided, including a memory and a processor, the memory being used to store one or more computer program instructions, wherein the one or more computer program instructions are executed by the processor to implement the methods described in the first, second, or third aspects above.

[0046] This invention analyzes the charging messages reported by the charging pile during the charging process. Charging messages whose multi-gun parallel charging self-test results are pending verification are stored. When the number of charging messages pending verification exceeds a predetermined number, a reverse lookup is performed on these messages to determine the corresponding target charging order. If the average current value of the target charging order is greater than a preset current value, the target charging order is determined to be a multi-gun parallel charging order.

[0065] Figure 1 This is a schematic diagram of a charging identification system according to an embodiment of the present invention. Figure 1 As shown, the charging identification system includes a server 11, a charging pile to be identified 12, an electric vehicle 13, and a user terminal 14.

[0066] In this embodiment, server 11 is a general-purpose data processing device that provides computing or application services to vehicle platform clients. It can be a single computer, a cluster of multiple computers, or a cloud server that can flexibly adjust computing resources through cloud technology. The charging pile to be identified 12 is a device that provides electrical energy replenishment to electric vehicle 13. It can transmit electrical energy from the power grid to the battery of electric vehicle 13 to meet the vehicle's driving needs. The charging pile to be identified 12 includes a charging pile body, a charging gun, a charging cable, and a communication cable. The charging pile body is connected to the charging gun via the charging cable and the communication cable. Multiple charging guns can be connected to one charging pile. The charging gun is used to connect to electric vehicle 13, the charging cable is used to charge electric vehicle 13, and the communication cable is used for data communication with electric vehicle 13. Electric vehicle 13 refers to a car powered by an onboard power source that needs to be charged by the charging pile to be identified 12 to store electrical energy. User terminal 14 is a terminal device used or held by the owner of electric vehicle 13. User terminal 14 is bound to electric vehicle 13. Specifically, user terminal 14 is a general terminal that can run charging platform client applications and mini-programs. For example, the terminal can be a mobile phone, computer, tablet computer, or in-vehicle computer. User terminal 14 is used to register, locate charging piles, receive and display charging data, etc. on the charging platform client application or mini-program.

[0067] In this embodiment, the server 11 interacts with the charging pile 12 to be identified and the user terminal 14 via the network to identify whether the charging pile 12 supports multi-gun charging. The information interaction process may include: a charging order generation stage, a charging message reporting stage, a charging pile identification stage, and a charging pile identification result application stage.

[0068] During the charging order generation stage, the server 11 generates a charging order by exchanging information with the user terminal 14 via the network.

[0069] Figure 2 This is an interactive flowchart of the charging order generation method according to an embodiment of the present invention. Figure 2 As shown, the interaction flow of the charging order generation method includes:

[0070] In step S201, user terminal 14 sends a charging pile query request to server 11.

[0071] The charging station query request must include the location of at least 13 electric vehicles.

[0072] In one possible implementation, the user terminal 14 is located at the same position as the electric vehicle 13. For example, the user terminal 14 is the on-board computer of the electric vehicle 13, or the user holds the movable user terminal 14 while sitting in the electric vehicle 13, in which case the position of the user terminal 14 can be taken as the position of the electric vehicle 13.

[0073] In one possible implementation, the user terminal 14 and the electric vehicle 13 are located at different locations. For example, the user holds a mobile user terminal 14 that is far away from the electric vehicle 13. In this case, the user terminal 14 should first determine the location of the electric vehicle 13 it is bound to, and then send a charging pile query request to the server 11 based on the location of the electric vehicle 13.

[0074] In one possible implementation, in addition to the location of the electric vehicle 13, the charging station query request may also carry the vehicle's charging requirements, such as charging power.

[0075] In step S202, server 11 determines multiple available charging piles 12 to be identified based on the charging pile query request.

[0076] Specifically, server 11 filters out multiple nearby available charging piles 12 based on information such as the location of electric vehicle 13 and / or vehicle charging needs.

[0077] In step S203, server 11 sends the available charging piles to be identified to user terminal 14.

[0078] Specifically, server 11 sends relevant information about each available charging pile 12 to user terminal 14, such as the charging pile identifier, location, distance from electric vehicle 13, and user reviews of the available charging pile 12.

[0079] In step S204, the user terminal 14 displays the received available charging piles to be identified 12.

[0080] In step S205, the user terminal 14 determines the target charging pile to be identified.

[0081] Specifically, the user terminal 14 obtains the user-selected charging pile 12 based on human-computer interaction with the user, and determines the user-selected charging pile 12 as the target charging pile 12.

[0082] In step S206, the user terminal 14 sends an order generation request carrying the target charging pile 12 to be identified to the server 11.

[0083] Specifically, the order generation request carries the charging pile identifier of the target charging pile 12 to be identified.

[0084] In step S207, server 11 generates a target charging order corresponding to the target charging pile 12 to be identified.

[0085] In step S207, server 11 sends a target order generation notification to user terminal 14 so that user terminal 14 displays the target order generation notification.

[0086] Figure 2The method for generating a target charging order shown is merely an example; the actual process for generating a target charging order can be determined based on specific circumstances. After generating the target charging order, server 11 stores the corresponding charging order data, which includes at least the mapping relationship between the charging order identifier and the charging gun identifier.

[0087] After generating the target charging order, the server 11 also sends a charging instruction to the charging pile 12 to be identified.

[0088] The charging message reporting phase begins after the charging gun establishes a physical connection with the electric vehicle 13 and starts charging. During the charging message reporting phase, the charging pile 12 to be identified generates a charging message through information interaction with the electric vehicle and completes the reporting of the charging message through information interaction with the server 11.

[0089] Specifically, the charging pile 12 to be identified and the electric vehicle 13 establish a physical connection through charging guns and charging sockets. The charging pile 12 to be identified includes multiple charging guns, and the electric vehicle 13 may also include one or more charging sockets. At least one charging gun of the charging pile 12 to be identified establishes a physical connection with the charging socket of the electric vehicle 13. For example, the charging pile 12 to be identified includes three charging guns. These three charging guns can connect to three different electric vehicles 13, or two charging guns can connect to one electric vehicle 13, and another charging gun can connect to another electric vehicle 13, or all three charging guns can connect to the same electric vehicle 13.

[0090] After establishing a physical connection between the charging pile 12 and the electric vehicle 13, the charging pile 12 sends an authentication message to the electric vehicle 13 to confirm the vehicle identification and charging permissions, thereby ensuring the safety and legality of charging. After the electric vehicle 13 returns the corresponding vehicle identification and charging permissions to the charging pile 12, the charging pile 12 and the electric vehicle 13 exchange information based on messages such as charging request messages, charging parameter negotiation messages, and charging start indication messages, so that the charging pile 12 can begin charging the electric vehicle 13. After charging begins, the charging pile 12 monitors the charging process and generates charging messages. Specifically, the charging pile 12 to be identified determines the charging information such as current and voltage corresponding to each charging gun according to a preset time period, determines the vehicle identification of the electric vehicle 13 connected to each charging gun, and generates a multi-gun parallel charging self-test result based on whether the vehicle identifications corresponding to different charging guns are the same. If the vehicle identification corresponding to a certain charging gun is different from the vehicle identifications of other charging guns on the charging pile 12 to be identified, then the multi-gun parallel charging self-test result corresponding to that charging gun is determined to be unsupported for multi-gun parallel charging. If the vehicle identification corresponding to a certain charging gun is the same as the vehicle identification of any other charging gun on the charging pile 12 to be identified, then the multi-gun parallel charging self-test result corresponding to that charging gun is determined to be pending verification. The charging pile 12 to be identified reports the charging messages of each charging gun corresponding to the charging pile 12 to the server 11. The charging messages of the charging guns may include information such as the charging pile identification, charging gun identification, current value, voltage value, multi-gun parallel charging self-test result, and reporting timestamp. The self-test results of multi-gun charging can be represented in the form of fields. For example, the self-test results of multi-gun charging can be identified by the reverse5 field. A value of 0 in the reverse5 field indicates that the self-test results of multi-gun charging are not supported, and a value of 1 in the reverse5 field indicates that the self-test results of multi-gun charging are pending review.

[0091] In one possible implementation, the charging pile 12 to be identified can also synchronize the charging message to the electric vehicle 13, so that the electric vehicle 13 and the user terminal 14 bound to the electric vehicle 13 can display the corresponding charging information. Furthermore, the electric vehicle 13 and / or the user terminal 14 can also upload the charging message to the server.

[0092] The aforementioned charging order generation stage and charging message reporting stage constitute the data collection stage. Server 11 collects charging order data during the charging order generation stage and charging messages during the charging message reporting stage. After entering the charging pile identification stage, server 11 identifies whether the charging pile 12 to be identified supports multi-gun parallel charging based on the charging order data and charging messages.

[0093] Figure 3 This is a flowchart of a charging pile identification method according to an embodiment of the present invention. Figure 3 As shown, the charging pile identification method on the server side includes:

[0094] Step S301: Obtain the multi-gun parallel charging self-test result of the charging pile 12 to be identified from the charging message.

[0095] Among them, multi-gun charging refers to the charging pile supporting multiple charging guns to charge the same vehicle. The self-test result of multi-gun charging may be that it does not support multi-gun charging or needs to be verified. Since the self-test level of the charging pile 12 to be identified is poor, when it is determined that the charging pile 12 to be identified may support multi-gun charging, the charging message is uploaded to the server 11 so that the server 11 can verify the self-test result of multi-gun charging of the charging pile 12 to be identified.

[0096] Step S302: Determine whether the self-test result of the multi-gun parallel charging is pending verification.

[0097] If yes, proceed to step S304; otherwise, proceed to step S303.

[0098] Step S303: Discard the charging message.

[0099] Step S304: Store the corresponding charging message in the message queue to be reviewed corresponding to the charging pile 12 to be identified.

[0100] Steps S301-S304 above constitute the charging message data cleaning stage. Server 11 cleans the message data based on the multi-gun parallel charging self-test results in the charging message, and retains the multi-gun parallel charging self-test results as the charging messages to be reviewed.

[0101] Step S305: Determine that the number of charging messages in the message queue to be reviewed is greater than the preset number of messages.

[0102] The preset message count can be set and adjusted according to the actual situation. For example, the preset message count can be 5, 10, 20, etc.

[0103] If yes, proceed to step S307; otherwise, proceed to step S306.

[0104] Step S306: End the current recognition process.

[0105] Step S307: Determine the target charging order corresponding to the message queue to be reviewed.

[0106] In one possible implementation, if the charging message is synchronized from the charging pile 12 to the electric vehicle 13 or user terminal 14 so that the electric vehicle 13 or user terminal 14 can upload it to the server 11, then when the electric vehicle 13 or user terminal 14 uploads the charging message, it can also encapsulate the charging identifier of the charging order that is being executed and bound to the electric vehicle 13 or user terminal 14 into the charging message, so that the corresponding target charging order can be directly determined according to the charging message.

[0107] In one possible implementation, the corresponding target charging order can be determined based on the reporting timestamp of the first charging message.

[0108] Figure 4 This is a flowchart illustrating the target charging order determination method according to an embodiment of the present invention. Figure 4 Therefore, the methods for determining target charging orders include:

[0109] Step S401: Determine the reporting timestamp corresponding to the first charging message in the message queue to be reviewed.

[0110] Step S402: Construct the review time interval based on the reporting timestamp of the first charging message.

[0111] Specifically, the review time interval can be constructed based on the reporting timestamp of the first charging message and preset construction rules. For example, if the reporting timestamp of the first charging message is X, then the review time interval can be [x-30min, x+1min]. The difference between the start and end timestamp of the review time interval and the reporting timestamp of the first charging message can be set.

[0112] Step S403: Determine the target charging order based on the charging pile identification and the review time interval.

[0113] Specifically, based on the charging pile identifier, the charging orders corresponding to the charging pile 12 to be identified within the verification time interval are determined. If there are multiple charging orders, the charging order with the smallest time difference between its start time and the reporting timestamp of the first charging message is determined as the target charging order. In other words, the order whose start time is closest to the reporting timestamp of the first charging message is selected as the target charging order.

[0114] Step S308: Determine the average current value of the target charging order.

[0115] The preset current value is a current value set in advance according to the charging parameters of various types of electric vehicles, such as 200A, 300A or 500A.

[0116] In one possible implementation, the average current value can be determined based on the current values ​​of multiple charging messages in the message queue to be reviewed.

[0117] In one possible implementation, multiple charging messages corresponding to the target charging order can be identified, and then the average current value can be determined based on the multiple charging messages.

[0118] Step S309: Determine whether the average current value is greater than the preset current value.

[0119] If yes, proceed to step S311; otherwise, proceed to step S310.

[0120] Step S310: End the current recognition process.

[0121] Step S311: Determine that the target charging order is a multi-gun parallel charging order.

[0122] Steps S305-S311 above constitute the multi-gun parallel charging order confirmation stage. Server 11 can filter out multi-gun parallel charging orders from the charging order data according to the above steps.

[0123] Step S312: Update the number of multi-gun parallel charging orders corresponding to the charging pile 12 to be identified.

[0124] Step S313: Determine whether the number of multi-gun parallel charging orders corresponding to the charging pile 12 to be identified is greater than the preset number of orders.

[0125] If yes, proceed to step S315; otherwise, proceed to step S314.

[0126] Step S314: Clear the queue of messages awaiting review.

[0127] Step S315: Determine that the identification result of the charging pile 12 to be identified is that it supports multi-gun parallel charging.

[0128] Steps S312-S315 above constitute the charging pile identification stage. The server 11 can identify whether the charging pile 12 to be identified supports multi-gun parallel charging based on the above steps.

[0129] It is worth noting that the charging order generation stage, charging message reporting stage, and charging pile identification stage can be executed sequentially or in isolation. If executed in isolation, the charging orders generated in the charging order generation stage can be stored in the corresponding order storage unit, and the mapping relationship between the multi-gun parallel charging orders obtained from cleaning the charging messages and the corresponding charging pile identifiers can be stored in the corresponding mapping relationship storage unit. All of these storage units can be data tables or databases, etc. When the amount of data in the order storage unit and the mapping relationship storage unit is sufficient, charging pile identification is initiated, that is, the multi-gun parallel charging orders corresponding to each charging pile 12 to be identified are determined, and the identification result of the charging pile 12 to be identified is determined based on the number of multi-gun parallel charging orders.

[0130] In the charging pile identification result application stage, the server 11 interacts with the charging pile 12 to be identified, the electric vehicle 13 and the user terminal 14 through the network, and uses the identification result of the charging pile 12 to optimize the charging pile utilization rate and improve the user charging experience.

[0131] In one possible implementation, the server 11 sends the corresponding identification result to the charging pile 12 to be identified, so that the charging pile 12 to be identified outputs the identification result and then prompts the user. For example, the charging pile 12 to be identified displays a prompt message that supports multi-gun charging on the display screen, or outputs a prompt message that supports multi-gun charging through a voice device, so that users who come to charge can select the appropriate charging pile according to their own vehicle model, thereby improving charging efficiency and charging pile utilization.

[0132] In one possible implementation, after determining the identification result of the charging pile 12 to be identified, the server 11 updates the safety monitoring policy of the charging pile 12. The current and voltage of charging piles supporting multi-gun charging are much higher than those of single-gun charging. Since most safety monitoring policies are configured for single-gun charging scenarios, they are very prone to falsely triggering platform safety policies in multi-gun charging scenarios, leading to problems such as charging restrictions and a poor user experience. Therefore, after identifying a charging pile that supports multi-gun charging, the safety monitoring policy for the charging pile to be identified can be updated to a multi-gun charging safety monitoring policy to customize the handling of multi-gun charging, minimize false alarms, and improve the user experience.

[0133] In one possible implementation, the user terminal 14 displays a multi-charger parallel charging query service and provides users with a multi-charger parallel charging pile recommendation service through information interaction with the server 11.

[0134] Figure 5 This is an interactive flowchart of the multi-gun parallel charging pile recommendation method according to an embodiment of the present invention. Figure 5 As shown, the interactive process of the multi-gun parallel charging pile recommendation method includes the following steps:

[0135] Step S501: Server 11 updates the corresponding charging map based on the identification result of the charging pile to be identified.

[0136] Among them, the charging map displays the identification results of charging piles that support multi-gun charging in parallel with a specific icon.

[0137] In step S502, the user terminal 14 displays the vehicle charging homepage.

[0138] The vehicle charging homepage includes a charging station query control.

[0139] In step S503, in response to the charging pile query control being triggered, the user terminal 14 sends a request to the server 11 to obtain the charging query page.

[0140] The charging query page request carries the location information of user terminal 14 and / or electric vehicle 13.

[0141] In step S504, in response to receiving the charging query page retrieval request sent by the user terminal 14, the server 11 sends a charging query page containing a charging map to the user terminal 14.

[0142] In step S505, server 11 sends a charging query page to user terminal 14.

[0143] In step S506, the user terminal 14 displays the charging query page containing the charging map returned by the server 11.

[0144] Figure 6 This is a schematic diagram of a charging query page according to an embodiment of the present invention. Figure 6 As shown, the charging query page 600 includes a map display control 601, a recommended charging station acquisition control 602, and a charging station confirmation control 603.

[0145] The map display control 601 is used to display a charging map, which shows multiple charging pile icons. Different types of charging piles have different icons, and charging piles with multiple charging guns are displayed with icons that distinguish them from ordinary charging piles. The charging map also displays a map pointer 604, which is used to select a charging pile on the map.

[0146] The recommended charging pile acquisition control 602 is used to send a corresponding multi-gun parallel charging request to the server 11 after being triggered.

[0147] The charging pile determination control 603 is used to determine the charging pile selected by the map pointer 604 and send an order generation request for the selected charging pile to the server 11.

[0148] In step S506, user terminal 14 can display as follows: Figure 6 The charging query page shown is for illustrative purposes only and does not limit the layout or the controls included in a typical charging query page.

[0149] In step S507, in response to the triggering of the recommended charging pile acquisition control, the user terminal 14 sends a corresponding multi-gun parallel charging request to the server 11.

[0150] The multi-gun parallel charging request can carry charging demand information, which may include the distance between the electric vehicle 13 and the recommended charging station, the user rating level of the recommended charging station, the charging parameters of the recommended charging station, etc. The charging parameters of the recommended charging station may include parameters such as current value, voltage value, and the maximum number of guns that can be supported for parallel charging.

[0151] In step S508, server 11 determines a recommended charging station from among the charging stations that support multi-gun charging based on the location of user terminal 14.

[0152] In one possible implementation, server 11 determines recommended charging stations based on the location of user terminal 14 and the aforementioned charging demand information.

[0153] In step S509, server 11 sends a recommended charging station to user terminal 14.

[0154] In step S510, the user terminal 14 displays the recommended charging station.

[0155] In summary, through information exchange in stages such as charging order generation, charging message reporting, charging pile identification, and application of charging pile identification results, it is possible to automatically identify and classify whether the charging pile to be identified supports multi-gun parallel charging based on the charging message reported by the charging pile to be identified. This eliminates the need for maintenance personnel to conduct on-site inspection and identification, reduces identification costs, and intelligently matches the corresponding charging pile to the charging vehicle based on the identification results, thereby optimizing the charging experience for car owners.

[0156] Figure 7 This is a flowchart of a charging pile identification method applicable to a server, according to an embodiment of the present invention. Figure 7 As shown, the charging pile identification method includes:

[0157] Step S701: Obtain the charging message reported by the charging pile to be identified according to a preset time period. The charging message includes the multi-gun parallel charging self-test result of the charging pile to be identified.

[0158] Step S702: In response to the self-test result of the multi-gun parallel charging being pending verification, the corresponding charging message is stored in the pending verification message queue corresponding to the charging pile to be identified.

[0159] Step S703: In response to the fact that the number of charging messages in the message queue to be reviewed is greater than the preset number of messages, the target charging order corresponding to the message queue to be reviewed is determined.

[0160] Step S704: Determine the average current value of the target charging order.

[0161] Step S705: In response to the average current value being greater than a preset current value, determine that the target charging order is a multi-gun parallel charging order.

[0162] Step S706: Update the number of multi-gun parallel charging orders corresponding to the charging pile to be identified.

[0163] Step S707: In response to the number of multi-gun charging orders being greater than the preset number of orders, the identification result of the charging pile to be identified is determined to be that it supports multi-gun charging. Multi-gun charging means that the corresponding charging pile supports multiple charging guns to charge the same car.

[0164] Steps S701-S707 described above are detailed in the above embodiment description and corresponding drawings, and will not be repeated here.

[0165] The method of this invention analyzes the charging messages reported by the charging pile to be identified during the charging process, stores the charging messages whose multi-gun parallel charging self-test results are pending verification, and when the number of charging messages to be verified exceeds a predetermined number, performs a reverse lookup on the charging messages to be verified to determine the corresponding target charging order. If the average current value of the target charging order is greater than a preset current value, the target charging order is determined to be a multi-gun parallel charging order. When the number of multi-gun parallel charging orders corresponding to the charging pile to be identified exceeds a preset number of orders, it is determined that the charging pile to be identified supports multi-gun parallel charging. The above method automatically identifies and classifies whether the charging pile to be identified supports multi-gun parallel charging based on the charging messages reported by the charging pile to be identified, eliminating the need for maintenance personnel to conduct on-site inspection and identification, reducing identification costs, and intelligently matching the corresponding charging pile to the charging vehicle according to the identification results, which can optimize the charging experience for car owners.

[0166] Figure 8 This is a flowchart of a charging pile identification method applicable to charging piles to be identified, according to an embodiment of the present invention. Figure 8 As shown, the charging pile identification method includes:

[0167] Step S801: Determine the charging information of each charging gun according to a preset time period, wherein the charging information includes the vehicle identifier.

[0168] In step S802, in response to the fact that at least two charging guns have the same vehicle identification, the multi-gun parallel charging self-test result is determined to be pending verification.

[0169] Step S803: Generate a corresponding charging message based on the multi-gun parallel charging self-test results.

[0170] Step S804: Report the charging message to the server.

[0171] Step S805: In response to receiving the identification result indicating that the charging pile to be identified supports multi-gun charging, the identification result is output to prompt the user.

[0172] Steps S801-S805 described above are detailed in the above embodiment description and corresponding drawings, and will not be repeated here.

[0173] The method of this invention automatically identifies and classifies whether the charging pile supports multi-gun parallel charging based on the charging message reported by the charging pile to be identified. This eliminates the need for maintenance personnel to conduct on-site inspection and identification, reducing identification costs. At the same time, it intelligently matches the corresponding charging pile to the charging vehicle based on the identification results, which can optimize the charging experience for car owners.

[0175] Step S901: Display the vehicle charging homepage, which includes a charging station query control.

[0176] Step S902: In response to the charging pile query control being triggered, a request to obtain the charging query page is sent to the server.

[0177] Step S903: Display the charging query page returned by the server, which includes a charging map. The charging map displays the identification results of charging piles that support multi-gun charging in parallel with specific icons. The identification results are determined based on whether the charging order corresponding to the charging pile to be identified is a multi-gun charging order. The multi-gun charging order is determined by review based on the multi-gun charging self-inspection results reported by the charging pile to be identified.

[0178] Step S904: In response to the triggering of the recommended charging pile acquisition control, a corresponding multi-gun parallel charging request is sent to the server.

[0179] Step S905: Display the recommended charging stations returned by the server.
