Description

Technical Field

[0001] This application relates to the technical field of charging control, and in particular to a communication control method and system for dual-gun charging. Background Technology

[0002] Electric vehicle charging standards stipulate that communication between charging equipment and electric vehicles is generally carried out using a PLC communication controller. The charging controller and the PLC communication controller use CAN communication. In dual-gun charging piles, each gun needs to be equipped with a PLC communication controller. The charging controller communicates with two PLC communication controllers through one or two sets of CAN communication. Therefore, interference can easily occur between the two PLCs, causing communication crosstalk. Summary of the Invention

[0003] To address at least one of the aforementioned technical problems, this application provides a communication control method, apparatus, device, and medium for dual-gun charging.

[0004] Firstly, this application provides a communication control method for dual-gun charging, employing the following technical solution:

[0005] Real-time detection of whether a charging vehicle is performing dual-gun charging behavior. If so, the first communication interface and first PLC conversion circuit corresponding to the first charging gun and the second communication interface and second PLC conversion circuit corresponding to the second charging gun are collected.

[0006] Based on the first communication interface and the first PLC conversion circuit, simulated network communication is performed to obtain the first communication channel;

[0007] Based on the second communication interface and the second PLC conversion circuit, simulated network communication is performed to obtain the second communication channel;

[0008] Network communication charging control is performed on the first charging gun and the second charging gun based on the first communication channel and the second communication channel, respectively.

[0009] By employing the above technical solution, the system detects in real time whether a vehicle is engaging in dual-gun charging. Upon detection, it collects data from the first communication interface and first PLC conversion circuit corresponding to the first charging gun, and the second communication interface and second PLC conversion circuit corresponding to the second charging gun. This ensures subsequent communication control is based on accurate information, guaranteeing the orderliness and stability of the dual-gun charging process. Based on the collected data from the first communication interface and first PLC conversion circuit, a simulated network communication is performed to obtain a first communication channel. The first communication interface, as the data transmission entry point, works in conjunction with the first PLC conversion circuit to convert and process the relevant data from the charging guns according to a specific protocol and format, simulating signals that meet network communication requirements, thus constructing the first communication channel. This provides reliable communication assurance for subsequent precise control of the first charging gun, ensuring efficient and stable charging. Similarly, based on the second communication interface and second PLC conversion circuit, a simulated network communication is performed to obtain a second communication channel. The second communication interface and second PLC conversion circuit work together to convert and process the data from the second charging gun, simulating network communication signals to form the second communication channel. This avoids data transmission chaos and interference. Two independent communication channels correspond to the two charging guns respectively, providing an independent communication environment for simultaneous charging of both guns. This ensures that each charging gun can operate under stable communication conditions, improving the reliability and stability of dual-gun charging. Network communication charging control is performed on the first and second charging guns via the first and second communication channels respectively, avoiding signal crosstalk during dual-gun charging. This significantly improves charging safety and efficiency, providing a better user experience for the charging equipment.

[0010] In one possible implementation, the network communication charging control of the first charging gun and the second charging gun based on the first communication channel and the second communication channel respectively further includes:

[0011] The actual charging parameters of the first charging gun and the second charging gun, the first charging parameters transmitted through the first communication channel, and the second charging parameters transmitted through the second communication channel are collected.

[0012] Based on the parameter correspondence and the actual charging parameters, the first charging parameters and the second charging parameters are corrected to obtain the corrected first charging parameters and the second charging parameters.

[0013] In one possible implementation, the first charging parameter and the second charging parameter are corrected based on the parameter correspondence and the actual charging parameters to obtain the corrected first charging parameter and second charging parameter, including:

[0014] The actual charging parameters are compared with the first charging parameters and the second charging parameters according to the parameter correspondence relationship to obtain the parameter comparison results;

[0015] When the parameter comparison results show inconsistency, the operation parameter groups within the historical period are extracted according to the application duration of the first charging gun and the second charging gun, and the operation parameter groups are respectively input into the preset calibration algorithm for charging parameter calibration to obtain the corrected first charging parameters and second charging parameters.

If so, extract the abnormal charging data and group the abnormal charging data into pairs according to the charging gun operation timeline to obtain multiple abnormal charging groups.

[0018] Targeted optimization analysis was performed on the abnormal charging groups to obtain multiple target charging groups;

[0019] The actual charging parameters from multiple target charging groups and the first charging parameter / second charging parameter are input into the initial calibration algorithm for simulation calculation to obtain the first calibration coefficient and the second calibration coefficient of the initial calibration algorithm.

[0020] The initial calibration algorithm is updated based on the first calibration coefficient and the second calibration coefficient to obtain a preset calibration algorithm;

[0021] The actual charging parameters within the current time period are grouped in pairs according to the charging gun and the charging time to obtain the real-time charging parameter group.

[0022] The real-time charging parameter set is input into the preset calibration algorithm for correction calculation to obtain the corrected first charging parameter and second charging parameter.

[0023] In one possible implementation, the targeted optimization analysis of the abnormal charging group yields multiple target charging groups, including:

[0024] Calculate the corresponding parameter difference between the actual charging parameter in the abnormal parameter group and the first charging parameter / second charging parameter to obtain the first parameter difference corresponding to the abnormal parameter group;

[0025] The difference between the actual charging parameters and the first / second charging parameters within the current time period is calculated to obtain the second parameter difference.

[0026] The second parameter difference is compared with the first parameter difference one by one, and the abnormal parameter group corresponding to the first parameter difference that meets the preset difference matching condition is defined as the candidate parameter group.

[0027] The actual charging parameters within the current time period are used as filtering conditions to match and filter the actual charging parameters in the candidate parameter group, and the candidate parameter group that meets the preset parameter matching conditions is defined as the target parameter group.

[0028] In one possible implementation, when the parameter comparison result shows inconsistency, the method further includes:

[0029] The parameter comparison difference is determined based on the parameter comparison result, and it is determined whether the parameter comparison difference is greater than the preset comparison threshold. If it is greater, the corresponding abnormal charging gun is determined based on the parameter comparison result, and the charging abnormal parameters and charging abnormal location corresponding to the abnormal charging gun are sent to the target terminal.

[0051] The embodiments of this application will now be described in further detail with reference to the accompanying drawings.

[0052] This application provides a communication control method for dual-gun charging, executed by an electronic device, which can be a server or a terminal device. The server can be a standalone physical server, a server cluster or distributed system composed of multiple physical servers, or a cloud server providing cloud computing services. The terminal device can be a smartphone, tablet, laptop, desktop computer, etc., but is not limited to these.

Figure 1 As shown, the method includes:

[0053] Step S10: Real-time detection of whether there is a charging vehicle performing dual-gun charging behavior. If so, the first communication interface and first PLC conversion circuit corresponding to the first charging gun and the second communication interface and second PLC conversion circuit corresponding to the second charging gun are collected.

[0054] In the embodiments of this application, dual-gun charging behavior refers to the operation mode in which the same charging pile simultaneously provides power to the two charging interfaces of two vehicles through two charging guns, representing a scenario of multi-gun coordinated charging; the first charging gun and the second charging gun respectively represent two independent charging interface devices configured on the charging pile, used to distinguish different charging channels. The first communication interface and the second communication interface refer to the physical or logical interfaces (such as CAN bus, RS485 interface) for data interaction between the charging gun and the charging pile control unit, used to represent signal transmission channels. The first PLC conversion circuit and the second PLC conversion circuit refer to circuit modules that convert charging pile control signals (such as power distribution commands) into levels or protocol formats suitable for transmission through the communication interface, used to represent signal adaptation and conversion functions.

[0055] Specifically, the physical connection status of the charging interfaces is monitored in real time via the charging pile's built-in current sensor or vehicle connection status detection module (e.g., charging gun insertion signal, vehicle BMS communication activation signal). If both charging interfaces of the same charging pile are detected to be in a "connected" state, and the corresponding charging request parameters sent by the vehicle BMS (e.g., required voltage and current) are valid, then dual-gun charging is determined to be occurring. At this time, the system activates the data acquisition module and performs the following operations for the first and second charging guns respectively:

[0056] Collect data from the first charging gun: Read real-time charging parameters (such as SOC and remaining charging time) sent by the vehicle BMS through the first communication interface (such as CAN bus), and at the same time collect the input / output signals (such as control command level and isolation status indicator) of the first PLC conversion circuit to verify the accuracy of signal conversion;

[0057] Collect data from the second charging gun: Obtain BMS data from another vehicle through the second communication interface (such as RS485), and monitor the working status of the second PLC conversion circuit (such as temperature and power consumption) to ensure that it does not interfere with the first channel;

[0058] Data synchronization and storage: After timestamping the data collected from both channels, the data is synchronously stored in a local database or uploaded to a cloud platform for subsequent analysis of indicators such as power distribution balance and communication stability of dual-gun charging.

[0059] Step S11: Perform simulated network communication based on the first communication interface and the first PLC conversion circuit to obtain the first communication channel.

[0060] In this embodiment of the application, simulated network communication refers to simulating the data transmission process in a real network environment through software simulation or hardware testing platform, in order to verify the compatibility and stability of the communication interface and conversion circuit.

[0061] Specifically, the steps for preparing the simulation test environment for the first communication channel include:

[0062] Hardware connection: Connect the first communication interface (CAN interface) to the test equipment (such as a CAN analyzer on a PC or a dedicated communication tester) through a standard cable, while ensuring that the first PLC conversion circuit has been correctly integrated into the charging pile control board;

[0063] Software configuration: Load the communication protocol stack (such as CANopen, J1939) into the test equipment and configure the same communication parameters as the vehicle BMS (such as baud rate, message ID range).

[0064] Signal simulation: Simulated data is generated using testing software (such as periodically sending SOC messages and randomly inserting error frames) to simulate the communication load under real charging scenarios;

[0065] Data transmission: Analog data undergoes level conversion (e.g., TTL→CAN differential level) and protocol encapsulation (e.g., CRC check) via the first PLC conversion circuit, and is then sent to the charging pile control unit through the first communication interface;

[0066] Channel verification: Monitor the received data of the control unit (e.g., through LED indicators or log records) to confirm that there is no data loss or error, and at the same time test the integrity of reverse communication (e.g., the control unit issues power adjustment commands), and finally form a verification report of the first communication channel.

[0067] Step S12: Perform simulated network communication based on the second communication interface and the second PLC conversion circuit to obtain the second communication channel.

[0068] Specifically, the steps for preparing the simulation test environment for the second communication channel include:

[0069] Hardware connection: Connect the second communication interface (RS485 interface) to the test equipment (such as a serial port debugging tool on a PC or a dedicated protocol analyzer) through a standard cable, and at the same time ensure that the second PLC conversion circuit has been correctly soldered to the charging pile control board;

[0070] Software configuration: Install the corresponding protocol driver (such as RS485 to USB driver) on the test equipment and configure the same communication parameters as the vehicle BMS (such as baud rate 9600, data bits 8, stop bits 1).

[0071] Signal simulation: Generate simulated data using testing software (e.g., periodically send "SOC=80%" messages, or randomly insert error frames to simulate interference scenarios). If the second interface supports multiple protocols (e.g., simultaneously support Modbus and custom protocols), the compatibility of each protocol must be tested separately.

[0072] Data transmission and conversion: The analog data undergoes level conversion (TTL→RS485 differential level) and protocol encapsulation (such as adding check bits, frame headers and frame trailers) via the second PLC conversion circuit. The converted data is then sent to the charging pile control unit through the second communication interface, while simultaneously testing the integrity of reverse communication (such as the control unit issuing a "stop charging" command).

[0073] Channel verification: Monitor the receiving log of the control unit (e.g., via LED indicators or serial port debugging assistant) to confirm that there is no data loss or garbled characters. Use an oscilloscope or logic analyzer to capture the physical layer signals of the second communication interface (e.g., the A / B line voltage waveform of RS485) to verify the accuracy of level conversion.

[0074] Generate a test report to record key metrics such as throughput, latency, and error rate of the second communication channel.

[0075] Step S13: Perform network communication charging control on the first charging gun and the second charging gun based on the first communication channel and the second communication channel respectively.

[0076] Specifically, under the premise of ensuring that the first communication channel and the second communication channel meet the control signal transmission task, the charging output tasks for the first charging gun and the second charging gun are executed respectively.

[0077] Based on the above embodiments, the system detects in real time whether a vehicle is performing dual-gun charging. Upon detection, it collects data from the first communication interface and first PLC conversion circuit corresponding to the first charging gun, and the second communication interface and second PLC conversion circuit corresponding to the second charging gun. This ensures subsequent communication control is based on accurate information, guaranteeing the orderliness and stability of the dual-gun charging process. A first communication channel is obtained by simulating network communication based on the collected first communication interface and first PLC conversion circuit. The first communication interface, as the data transmission entry point, works in conjunction with the first PLC conversion circuit to convert and process the relevant data from the charging gun according to a specific protocol and format, simulating signals that meet network communication requirements, thereby constructing the first communication channel. This provides reliable communication assurance for subsequent precise control of the first charging gun, ensuring efficient and stable charging. A second communication channel is obtained by simulating network communication based on the second communication interface and second PLC conversion circuit, similarly to constructing the first communication channel. The second communication interface and second PLC conversion circuit cooperate to convert and process the data from the second charging gun, simulating network communication signals to form the second communication channel. This avoids data transmission chaos and interference. Two independent communication channels correspond to the two charging guns respectively, providing an independent communication environment for simultaneous charging of both guns. This ensures that each charging gun can operate under stable communication conditions, improving the reliability and stability of dual-gun charging. Network communication charging control is performed on the first and second charging guns via the first and second communication channels respectively, avoiding signal crosstalk during dual-gun charging. This significantly improves charging safety and efficiency, providing a better user experience for the charging equipment.

[0078] Furthermore, since the charging parameters of the first and second charging guns are prone to inconsistencies with the pre-configured parameters during long-term use, in order to ensure that the first and second charging guns can receive charging control commands normally and charge the vehicle according to the charging parameters in the charging control commands, this application includes network communication charging control of the first and second charging guns based on the first and second communication channels respectively. Before this, the application also includes: collecting the actual charging parameters of the first and second charging guns, the first charging parameters transmitted through the first communication channel, and the second charging parameters transmitted through the second communication channel; and correcting the first and second charging parameters based on the parameter correspondence and the actual charging parameters to obtain the corrected first and second charging parameters.

[0079] Specifically, the actual charging parameters are compared with the first charging parameters and the second charging parameters according to the parameter correspondence to obtain the parameter comparison results. When the parameter comparison results show inconsistencies, the operation parameter groups within the historical period are extracted according to the application duration of the first charging gun and the second charging gun, and the operation parameter groups are respectively input into the preset calibration algorithm for charging parameter calibration to obtain the corrected first charging parameters and second charging parameters.

[0080] In this embodiment, the preset calibration algorithm is: y=ax+b, where y is the actual charging parameter, a is the first charging parameter, b is the second charging parameter, and x is either the first charging parameter or the second charging parameter.

[0081] Specifically, the actual charging parameters are compared with the first charging parameters and the second charging parameters according to the parameter correspondence to obtain the parameter comparison results. When the parameter comparison results show inconsistencies, the operation parameter groups within the historical period are extracted according to the application duration of the first charging gun and the second charging gun, and the operation parameter groups are respectively input into the preset calibration algorithm for charging parameter calibration to obtain the corrected first charging parameters and second charging parameters.

[0082] Specifically, the process involves determining whether there are any abnormal charging data in the operational parameter group where the charging parameters transmitted through the communication channel do not match the actual output charging parameters of the charging gun. If so, the abnormal charging data is extracted and grouped in pairs according to the charging gun's operational timeline, resulting in multiple abnormal charging groups. Targeted optimization analysis is then performed on these abnormal charging groups to obtain multiple target charging groups. The actual charging parameters from these target charging groups, along with the first / second charging parameters, are input into the initial calibration algorithm for simulation calculations, yielding the first and second calibration coefficients. The initial calibration algorithm is then updated based on these first and second calibration coefficients to obtain a preset calibration algorithm. The actual charging parameters within the current time period are then grouped in pairs according to the charging gun and charging time, resulting in a real-time charging parameter group. This real-time charging parameter group is input into the preset calibration algorithm for correction calculations, yielding the corrected first and second charging parameters.

[0083] Specifically, the differences between the actual charging parameters in the abnormal parameter groups and the first / second charging parameters are calculated to obtain the first parameter difference corresponding to the abnormal parameter groups. The differences between the actual charging parameters within the current time period and the first / second charging parameters are also calculated to obtain the second parameter difference. The second parameter difference is compared one by one with the first parameter difference, and the abnormal parameter groups corresponding to the first parameter difference that meet the preset difference matching conditions are defined as candidate parameter groups. The actual charging parameters within the current time period are used as the filtering condition to match and filter the actual charging parameters in the candidate parameter groups, and the candidate parameter groups that meet the preset parameter matching conditions are defined as the target parameter group.

[0084] Furthermore, the parameter comparison difference is determined based on the parameter comparison results, and it is determined whether the parameter comparison difference is greater than the preset comparison threshold. If it is greater, the corresponding abnormal charging gun is determined based on the parameter comparison results, and the charging abnormal parameters and charging abnormal location corresponding to the abnormal charging gun are sent to the target terminal.

[0085] In this embodiment of the application, the preset comparison threshold is used to represent the maximum parameter error value that the charging gun can withstand.
