Description

Technical Field

[0001] This application relates to the field of vehicle charging control technology, and in particular to a method for handling abnormal vehicle charging connection status and a vehicle. Background Technology

[0002] To prevent accidental operation of new energy vehicles during charging and to avoid the risk of electric shock from exposed high-voltage interfaces, the common practice is to link the vehicle's power-on or charging strategy to the connection status of the external charging gun. For example, the vehicle is only allowed to enter charging mode when it is detected that it is connected to the external charging gun (i.e., in the connected state), while high-voltage power-on is prohibited to prevent accidental operation during charging. When the vehicle is detected that it is not connected to the external charging gun (i.e., in the disconnected state), high-voltage power-on is allowed, while the vehicle is prohibited from entering charging mode to prevent exposure of the high-voltage interface and reduce the risk of electric shock.

[0003] In real-world vehicle use, factors such as hardware malfunctions, obstructions, or poor wiring connections may cause a discrepancy between the detected charging connection status and the actual charging connection status, resulting in an abnormal charging connection status. This can lead to the incorrect triggering of the aforementioned association strategies, affecting the normal use of the vehicle. For example, the system might incorrectly detect a connected vehicle when it is not actually connected to the charging gun, preventing the user from driving on high voltage or even causing a sudden drop in voltage while driving. Conversely, it might incorrectly detect a disconnected vehicle when it is actually connected to the charging gun, preventing the user from charging the vehicle normally.

[0004] Related technologies can ignore the detected charging connection status during driving to avoid sudden drops in high voltage while driving due to abnormal charging connection status. However, when the vehicle is stationary and the charging connection status is abnormal, there are still issues where users cannot access high voltage or charge their vehicles, severely impacting the user experience.

[0005] It should be noted that the information disclosed in the background section of this application is intended only to enhance the understanding of the general background of this application, and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0006] This application provides a method and vehicle for handling abnormal charging connection status, which helps to solve the problem that users cannot drive on high voltage or cannot charge when there is an abnormal charging connection status.

[0007] In a first aspect, embodiments of this application provide a method for handling abnormal vehicle charging connection status, applied to an in-vehicle interaction module, the method comprising: If a charging connection error signal is received when the vehicle is stationary, a charging connection error prompt message will be output, which is used to prompt the user to confirm the charging connection. Based on the user's input confirmation of the charging connection, the system sends the corresponding actual charging connection status to the vehicle controller. The vehicle controller is used to control the vehicle to switch to charging mode or driving mode based on the actual charging connection status.

[0008] In some possible implementations, sending the corresponding actual charging connection status to the vehicle controller based on the user-input charging connection confirmation operation includes: If a user inputs a first charging connection confirmation operation, the system sends a first actual charging connection status to the vehicle controller. The vehicle controller controls the vehicle to switch to a charging mode based on the first actual charging connection status. The first actual charging connection status indicates that the charging module is in a connected state. If a second charging connection confirmation operation is received from the user, a second actual charging connection status is sent to the vehicle controller. The vehicle controller controls the vehicle to switch to a drivable mode based on the second actual charging connection status, which indicates that the charging module is in an unconnected state.

[0009] Secondly, embodiments of this application provide a method for handling abnormal vehicle charging connection status, applied to a charging module, the method comprising: Charge connection detection signals are collected according to preset time intervals; If the charging connection detection signal meets the preset abnormal conditions, a charging connection abnormal signal is sent to the vehicle interaction module.

[0010] In some possible implementations, the step of sending a charging connection abnormality signal to the vehicle interaction module if the charging connection detection signal meets a preset abnormality condition includes: Receive the vehicle's speed; If the vehicle's speed exceeds a preset speed threshold and the charging connection detection signal meets preset abnormal conditions, a charging connection abnormal signal is sent to the vehicle interaction module.

[0011] In some possible implementations, the step of acquiring the charging connection detection signal according to a preset time interval includes: acquiring the resistance value of the charging access resistor according to a preset time interval; If the charging connection detection signal meets the preset abnormal conditions, a charging connection abnormal signal is sent to the vehicle interaction module, including: if the resistance value of the charging access resistor is less than the first preset resistance value and does not belong to the preset recognition range, a charging connection abnormal signal is sent to the vehicle interaction module.

[0012] In some possible implementations, the step of sending a charging connection abnormality signal to the vehicle interaction module if the charging connection detection signal meets a preset abnormality condition includes: If the charging connection detection signal meets the preset abnormal conditions, a charging connection abnormal signal is sent to the vehicle interaction module and the cloud platform. If the cloud platform receives the charging connection abnormal signal, it sends a charging connection abnormal alarm notification to the user's mobile device.

[0013] Thirdly, embodiments of this application provide a method for handling abnormal vehicle charging connection status, applied to a vehicle controller, the method comprising: Receive the actual charging connection status sent by the in-vehicle interaction module; Based on the actual charging connection status, the vehicle is controlled to switch between charging mode and driving mode.

[0014] In some possible implementations, controlling the vehicle to switch to a charging mode or a drivable mode based on the actual charging connection state includes: If the vehicle receives the first actual charging connection status sent by the vehicle interaction module, the vehicle is controlled to switch to the charging mode. The first actual charging connection status is used to indicate that the charging module is in a connected state. If the vehicle receives a second actual charging connection status from the in-vehicle interaction module, the vehicle is controlled to switch to drivable mode. The second actual charging connection status indicates that the charging module is in an unconnected state.

[0015] In some possible implementations, after controlling the vehicle to switch to rechargeable mode, the method further includes: A charging control signal is sent to the charging module, which controls the vehicle to charge according to a preset charging mode based on the charging control signal. The charging power and / or input current of the preset charging mode is less than the charging power and / or input current of the conventional charging mode.

[0016] Fourthly, embodiments of this application provide a vehicle, including: An in-vehicle interaction module, wherein the in-vehicle interaction module is configured to perform any of the methods described in the first aspect; A charging module, the charging module being configured to perform any of the methods described in the second aspect; A vehicle controller, which is configured to perform any of the methods described in the third aspect.

[0017] In this embodiment, when the vehicle is stationary, if the in-vehicle interaction module receives a charging connection error signal, it outputs a charging connection error prompt to remind the user to confirm the charging connection. Then, based on the user's input confirmation, it sends the actual charging connection status to the vehicle controller. The vehicle controller then controls the vehicle to switch to either a charging mode or a driving mode based on the actual charging connection status. It is understood that when the charging connection status is abnormal, the user can use the in-vehicle interaction module and the vehicle controller to control the vehicle to enter the mode corresponding to the actual charging connection status, thus enabling normal high-voltage driving or charging, which can improve the user experience.

Detailed Implementation

[0020] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0021] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0022] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0023] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0024] To prevent new energy vehicles from being misoperated during charging and to avoid the risk of electric shock from exposed high-voltage interfaces, the usual practice is to link the vehicle's power-on or charging strategy with the connection status of the external charging gun.

[0025] For example, the vehicle is only allowed to enter the charging mode when it is detected that it is connected to an external charging gun (i.e., connected state), and the high voltage power supply to the vehicle is prohibited to avoid accidental operation of the vehicle during charging. When the vehicle is detected that it is not connected to an external charging gun (i.e., disconnected state), the high voltage power supply to the vehicle is allowed, and the vehicle is prohibited from entering the charging mode to prevent the high voltage interface from being exposed and reduce the risk of electric shock.

[0026] In real-world vehicle use, factors such as hardware malfunctions, foreign object blockages, or poor wiring harness contact may cause the detected charging connection status to differ from the actual charging connection status, resulting in an abnormal charging connection status. This can then incorrectly trigger the aforementioned association strategy, affecting the normal use of the vehicle.

[0027] See Figure 1 This is a schematic diagram illustrating an application scenario provided in an embodiment of this application, such as... Figure 1 As shown in A, when vehicle 1011 is actually connected to the charging gun of charging pile 1012, an error occurs in detecting that vehicle 1011 is not currently connected to the charging gun (is in an unconnected state), causing the user to be unable to charge the vehicle normally. Figure 1 As shown in B, when the vehicle 1021 is not actually connected to the charging gun or the charging pile 1022, it is incorrectly detected that the vehicle 1021 is currently connected to the charging gun (in a connected state), which in turn causes the user to be unable to drive on the high voltage, or even to suddenly lose the high voltage during driving.

[0028] Related technologies can ignore the detected charging connection status during driving to avoid sudden drops in high voltage while driving due to abnormal charging connection status. However, when the vehicle is stationary and the charging connection status is abnormal, there are still issues where users cannot access high voltage or charge their vehicles, severely impacting the user experience.

[0029] In view of this, the present application provides a method for handling abnormal vehicle charging connection status, which helps to solve the problem that users cannot drive on high voltage or cannot charge when there is an abnormal charging connection status.

[0030] See Figure 2 This is a flowchart illustrating a method for handling abnormal vehicle charging connection status provided in an embodiment of this application. Figure 2 As shown, it can be applied to, for example Figure 1 The application scenario shown includes the following steps.

[0031] S201: When the vehicle is stationary, if the vehicle interaction module receives a charging connection error signal, it will output a charging connection error message.

[0032] The charging connection error message is used to prompt the user to confirm the charging connection.

[0033] In the embodiments of this application, the charging connection abnormality signal is usually used to characterize the signal that the detected charging connection state does not match the actual charging connection state, that is, the charging connection state is abnormal.

[0034] Furthermore, an in-vehicle interaction module typically refers to the hardware or software within a vehicle used to enable information interaction between the user and the vehicle. It can receive user input commands and provide feedback on vehicle status information or prompts to the user. Specifically, an in-vehicle interaction module may include a touchscreen display of an in-vehicle entertainment system, a voice assistant system, and / or physical buttons located within the vehicle.

[0035] When the in-vehicle interaction module receives a charging connection error signal, it can output a corresponding charging connection error message to prompt the user to confirm the charging connection. This charging connection error message, generated and output by the in-vehicle interaction module, clearly indicates to the user that there may be an abnormal charging connection status and guides the user to perform the appropriate confirmation action.

[0036] Specifically, the in-vehicle interaction module can output charging connection error messages in various ways. For example, when the in-vehicle interaction module is a touchscreen display of an in-vehicle entertainment system, the charging connection error message can be a text prompt, pop-up window, or graphic icon displayed on the screen. When the in-vehicle interaction module is a voice assistant system, the charging connection error message can be a voice announcement broadcast through the vehicle's speakers. When the in-vehicle interaction module includes physical buttons or indicator lights, the charging connection error message can be a specific flashing pattern of the indicator light or a specific prompt sound emitted by a buzzer.

[0037] Furthermore, the charging connection abnormality signal can be determined in several ways, and then sent to the in-vehicle interaction module. For example, the user can determine that the charging connection status is abnormal and then input a charging connection abnormality signal, which the in-vehicle interaction module can receive; alternatively, other modules in the vehicle can determine the charging connection status abnormality and send a charging connection abnormality signal to the in-vehicle interaction module.

[0038] In some possible implementations, when the vehicle is stationary, the in-vehicle interaction module responds to a charging connection error signal input by the user and outputs a charging connection error message.

[0039] Specifically, when a user opens the charging port and connects an external charging gun to attempt charging, or when a user presses the brake to try and bring the vehicle into READY mode for driving, they may find that the detected charging connection status does not match the actual charging connection status. Users can browse the user interface (UI) on the in-vehicle infotainment system's touchscreen display and input a charging connection error signal using virtual buttons or other controls within the UI. The in-vehicle interaction module receives the user's input charging connection error signal and triggers a charging connection error prompt, such as displaying corresponding text prompts, pop-ups, or graphic icons on the UI, to prompt the user to confirm the charging connection.

[0040] S202: The vehicle interaction module sends the corresponding actual charging connection status to the vehicle controller based on the user's input of the charging connection confirmation operation.

[0041] In this embodiment, the charging connection confirmation operation typically refers to a user operation whereby, based on the user's judgment of the vehicle's current state, inputs the actual charging connection status of the vehicle through the in-vehicle interaction module. In this way, the actual charging connection status determined by the charging connection confirmation operation can overwrite or correct any potentially abnormal charging connection status detected by the vehicle.

[0042] Specifically, after receiving a charging connection error message, the user can perform corresponding actions based on the message. The in-vehicle interaction module can receive a charging connection confirmation action input by the user in response to the message. The specific form of the charging connection confirmation action can be related to the type of in-vehicle interaction module. For example, when the in-vehicle interaction module is a touchscreen display of an in-vehicle entertainment system, the charging connection confirmation action can be the user clicking on a virtual option displayed on the screen such as "Charging gun connected" or "Charging gun not connected." When the in-vehicle interaction module is a voice assistant system, the charging connection confirmation action can be the user speaking a voice command such as "Connected" or "Not connected."

[0043] As we understand it, the Vehicle Control Unit (VCU) is typically the core control unit of a vehicle, used to coordinate and manage the overall operation of the vehicle. It can receive signals and instructions from different modules of the vehicle and send control commands to other relevant controllers according to preset control strategies to achieve unified control of functions such as vehicle power, charging, and network management. The in-vehicle interaction module and the VCU can exchange data through the vehicle's internal communication network. When the in-vehicle interaction module receives a user's confirmation of the charging connection, it can send the corresponding actual charging connection status to the VCU through the in-vehicle communication network.

[0044] S203: The vehicle controller controls the vehicle to switch to either a charging mode or a driving mode based on the actual charging connection status.

[0045] In this embodiment, the vehicle controller can receive the actual charging connection status sent by the vehicle interaction module, and control the vehicle to switch to charging mode or driving mode according to the actual charging connection status.

[0046] In this way, when the charging connection status is abnormal, users can use the in-vehicle interaction module and the vehicle controller to control the vehicle to enter the mode corresponding to the actual charging connection status, and then drive or charge normally at high voltage, which can improve the user's driving experience.

[0047] See Figure 3 This is a flowchart illustrating another method for handling abnormal vehicle charging connection status provided in an embodiment of this application. Figure 3 As shown, in Figure 2 Based on the method shown, step S202 specifically includes the following steps.

[0048] S2021: If the in-vehicle interactive device receives the first charging connection confirmation operation input by the user, it sends the first actual charging connection status to the vehicle controller.

[0049] The first actual charging connection state is used to characterize that the charging module is in a connected state.

[0050] Understandably, when a user confirms that the external charging gun is reliably connected to the vehicle, but the vehicle does not correctly recognize it, the user can input a first charging connection confirmation operation through the in-vehicle interaction module. For example, when the in-vehicle interaction module is a touch-sensitive display screen of the in-vehicle entertainment system, the first charging connection confirmation operation can be the user clicking on the "Charging gun connected" message displayed on the screen; when the in-vehicle interaction module is a voice assistant system, the charging connection confirmation operation can be the user speaking the voice command "Connected".

[0051] A charging module typically refers to the collection of hardware and software within a vehicle used to achieve charging functionality. A charging module may include an on-board charger, a charging interface, and related wiring harnesses and controllers. A charging module being in a connected state usually means that its physical interface has established a reliable mechanical and electrical connection with external charging equipment, enabling charging interaction.

[0052] After receiving the first charging connection confirmation operation input by the user, the vehicle interaction module can generate and send the first actual charging connection status corresponding to the first charging connection confirmation operation to the vehicle controller.

[0053] S2022: If the in-vehicle interactive device receives a second charging connection confirmation operation input by the user, it sends the second actual charging connection status to the vehicle controller.

[0054] The second actual charging connection state is used to characterize that the charging module is in an unconnected state.

[0055] Understandably, when a user confirms that the external charging gun has been completely removed, but the vehicle system still incorrectly displays a connected status, the user can input a second charging connection confirmation operation through the in-vehicle interaction module. For example, when the in-vehicle interaction module is a touchscreen display of the in-vehicle entertainment system, the first charging connection confirmation operation can be the user tapping the "Charging gun connected" message displayed on the screen; when the in-vehicle interaction module is a voice assistant system, the charging connection confirmation operation can be the user speaking the voice command "Connected".

[0056] In this context, "charging module in an unconnected state" usually means that there is no mechanical or electrical connection between the physical interface of the charging module and the external charging device, and the module does not have the conditions for charging interaction.

[0057] After receiving the second charging connection confirmation operation input by the user, the vehicle interaction module can generate and send the second actual charging connection status corresponding to the second charging connection confirmation operation to the vehicle controller.

[0058] In some possible implementations, such as Figure 3 As shown, in Figure 2Based on the method shown, step S203 specifically includes the following steps.

[0059] S2031: If the vehicle controller receives the first actual charging connection status, it controls the vehicle to switch to rechargeable mode.

[0060] In this embodiment, the vehicle controller can receive a first actual charging connection status sent by the vehicle interaction module. The first actual charging connection status is used to indicate that the charging module is in a connected state.

[0061] When the vehicle controller receives the first actual charging connection status from the in-vehicle interaction module, it can determine the user's intention to charge and then control the vehicle to switch to the charging mode.

[0062] Understandably, rechargeable mode generally refers to a working mode in which the vehicle is allowed to perform charging operations. When the vehicle is in rechargeable mode, the vehicle controller allows the vehicle to be charged through external charging devices such as external charging guns. At the same time, to prevent accidental operation of the vehicle during charging, it can also maintain a state of prohibition of high-voltage power supply to the vehicle's drive system.

[0063] In some possible implementations, after controlling the vehicle to switch to rechargeable mode, the method further includes: The vehicle controller sends a charging control signal to the charging module, which controls the vehicle to charge according to a preset charging mode based on the charging control signal. The input current of the preset charging mode is less than the input current of the conventional charging mode.

[0064] Understandably, when the vehicle controller switches to rechargeable mode based on the user-confirmed first actual charging connection state (i.e., the charging module is connected), although the vehicle is allowed to charge, a specific charging control signal is sent to the charging module to reduce potential risks during charging (such as overheating, short circuits, or charging interruptions due to poor contact) because an abnormal charging connection state was previously detected (e.g., hardware failure, poor contact, etc.). This charging control signal instructs the charging module to use a preset charging mode, and the input current of the preset charging mode is set to be lower than that of the normal charging mode (e.g., the normal charging mode may support a 10A input current, while the preset charging mode may be limited to 8A or lower). By reducing the charging current, basic charging functions can be maintained while reducing safety hazards caused by abnormal charging connections, providing a safer charging environment for users. The normal charging mode is then restored after the abnormal state is resolved.

[0065] S2032: If the vehicle controller receives the second actual charging connection status, it controls the vehicle to switch to drivable mode.

[0066] In this embodiment, the vehicle controller can receive a second actual charging connection status sent by the vehicle interaction module. The second actual charging connection status is used to indicate that the charging module is in an unconnected state.

[0067] When the vehicle controller receives the second actual charging connection status from the in-vehicle interaction module, it can determine the user's intention to drive and then control the vehicle to switch to a drivable mode.

[0068] Driving mode typically refers to a working mode in which a vehicle is allowed to be driven. When a vehicle is in driving mode, the vehicle controller can release the high-voltage power-on restriction on the vehicle's drive system, allowing the user to bring the vehicle into READY mode by operating the brakes, while simultaneously preventing the vehicle from entering the charging process.

[0069] In practical applications, the charging module can also proactively detect whether there are any abnormalities in the charging connection, and then proactively prompt the user to check the vehicle or confirm the charging connection, thereby improving the user experience.

[0070] See Figure 4 This is a flowchart illustrating another method for handling abnormal vehicle charging connection status provided in an embodiment of this application. Figure 4 As shown, in Figure 2 Based on the method shown, the following steps can also be included.

[0071] S301: The charging module collects charging connection detection signals according to a preset time interval.

[0072] In this embodiment of the application, the charging connection abnormality signal may also be a signal indicating that the vehicle's charging module may be malfunctioning.

[0073] As can be understood, charging connection detection signals typically refer to raw electrical signals or data generated by the charging module itself or its associated sensors, used to reflect the physical connection status of the charging interface. Examples include the mechanical latch signal used to confirm the insertion of the charging gun, and the level status on the charging connection confirmation and control guide lines defined in charging communication standards.

[0074] Furthermore, those skilled in the art can set a preset time interval according to actual conditions to control the time period for the charging module to perform signal acquisition operations. The preset time interval can be a fixed value or a variable dynamically adjusted according to the vehicle's status. Data is acquired according to the preset time interval.

[0075] In some possible implementations, the charging module collects the resistance value of the charging access resistor at preset time intervals.

[0076] It should be noted that external charging guns typically have a charging connection confirmation (Control Communication, CC) resistor with a specific resistance value configured according to the charging communication standard, which is used to characterize the charging specifications of the external charging gun in normal charging mode; the vehicle's charging module usually includes a charging connection detection circuit, which is used to detect the resistance value on the charging access circuit.

[0077] See Figure 5 This is a schematic diagram of a charging connection detection circuit provided in an embodiment of this application, as shown below. Figure 5 As shown, the charging connection detection circuit 500 includes a pull-up resistor R1. The first end of the pull-up resistor R1 is electrically connected to a reference power supply, and the second end of the pull-up resistor R1 is electrically connected to the first end of the charging access resistor R2. The second end of the charging access resistor R2 is connected to ground. The node between the second end of the pull-up resistor R1 and the first end of the charging access resistor R2 is electrically connected to the charging module controller.

[0078] When the charging module is normally connected to the external charging gun, the CC resistor inside the external charging gun serves as the charging connection resistor R2, which is connected to the charging connection detection circuit 500 of the vehicle charging module. The resistance value of the charging connection resistor R2 (the CC resistor inside the external charging gun) can then be determined by measuring the voltage at the node between the second terminal of the pull-up resistor R1 and the first terminal of the charging connection resistor R2. When the charging module is not connected to the external charging gun, the detection port of the charging connection detection circuit 500 is usually open-circuit, and the measured resistance value of the charging connection resistor R2 can be an infinite or very large value.

[0079] In practical applications, the resistance value of the CC resistor has a mapping relationship with the input current of the conventional charging mode. Therefore, the charging module can control the vehicle to charge according to the corresponding conventional charging mode based on the collected resistance value of the charging connection resistor. For example, if the detected resistance value of the charging connection resistor is 1500Ω, the vehicle will be controlled to charge according to the charging mode with an input current of 10A; if the detected resistance value is 680Ω, the vehicle will be controlled to charge according to the charging mode with an input current of 16A; and if the detected resistance value is 220Ω, the vehicle will be controlled to charge according to the charging mode with an input current of 32A.

[0080] S302: If the charging module determines that the charging connection detection signal meets the preset abnormal conditions, it sends a charging connection abnormal signal to the vehicle interaction module.

[0081] Understandably, the charging connection detection signal and preset abnormal conditions can be used to determine whether the vehicle is currently experiencing an abnormal charging connection. If the charging module determines that the charging connection detection signal meets the preset abnormal conditions, it can assume that the vehicle is currently experiencing an abnormal charging connection and send a charging connection abnormality signal to the in-vehicle interaction module. For example, if the mechanical locking signal confirms that the charging gun is properly inserted, but the current charging connection status is detected as not connected, it can be assumed that the vehicle is currently experiencing an abnormal charging connection and a charging connection abnormality signal will be sent to the in-vehicle interaction module.

[0082] In some possible implementations, if the charging module determines that the resistance value of the charging access resistor is less than the first preset resistance value and is not within the preset recognition range, it sends a charging connection abnormality signal to the vehicle interaction module.

[0083] Understandably, the first preset resistance value typically refers to a threshold value set in the charging connection detection circuit, used to distinguish between open and closed circuit states. The preset recognition range refers to the CC resistor value range defined according to the charging communication standard, corresponding to the conventional charging mode. When the resistance value is less than the first preset resistance value, it indicates that the charging access circuit is not in an open circuit state, and the resistance value is not within any preset recognition range. This indicates that the charging gun is not properly connected, suggesting potential issues such as poor contact, circuit faults, or abnormal charging gun configuration. In this case, the charging module can determine that the charging connection status is abnormal and send a charging connection abnormality signal to the vehicle interaction module.

[0084] In some possible implementations, if the charging module determines that the number of times the resistance value of the charging access resistor changes within a preset time range is greater than a preset threshold, it sends a charging connection abnormality signal to the vehicle interaction module.

[0085] Understandably, a change in the charging connection resistor value typically refers to the resistance value rapidly shifting from one stable state (such as a specific resistance value during normal connection or an open-circuit state when disconnected) to another stable state within a short period. Under normal circumstances, when the charging gun is stably connected to the vehicle's charging interface, the resistance value of the charging connection resistor should remain relatively stable and not change frequently; when the charging gun is not connected, the resistance value should also remain stable in an open-circuit state (such as infinity). If, within a preset time range, the number of times the charging connection resistor value changes exceeds a preset threshold, it indicates that there may be problems with the charging connection, such as poor contact, loose wiring, or unstable contact between the charging gun plug and the interface, leading to frequent fluctuations in the charging connection status. In this case, the charging module can determine that the charging connection status is abnormal and send a charging connection abnormality signal to the vehicle interaction module.

[0086] In some possible implementations, the vehicle's speed can also be received; if the charging module determines that the vehicle's speed is greater than a preset speed threshold and the charging connection detection signal meets a preset abnormal condition, then a charging connection abnormal signal is sent to the vehicle interaction module.

[0087] Understandably, a vehicle speed exceeding a preset speed threshold indicates that the vehicle is in motion. Normally, the vehicle will not connect to an external charging gun while in motion. Therefore, if the charging connection detection signal meets preset abnormal conditions (such as an abnormal resistance value in the charging connection resistor), it indicates a potential hardware fault (such as a faulty charging connection detection circuit or poor wiring harness contact) or an abnormal charging connection state, and will send a charging connection abnormality signal to the vehicle's interactive module.

[0088] In some possible implementations, if the charging module determines that the charging connection detection signal meets a preset abnormal condition, it sends a charging connection abnormal signal to the vehicle interaction module and the cloud platform. The cloud platform is used to send a charging connection abnormality alarm notification to the user's mobile device if it receives the charging connection abnormal signal.

[0089] Understandably, a charging connection error signal can be used to initiate a user notification process. As the core information interaction unit within the vehicle, the in-vehicle interaction module can directly provide users with immediate notifications of charging connection errors (e.g., through displaying text information on a screen, voice assistant announcements, or flashing indicator lights), ensuring users are aware of the error within the vehicle. The cloud platform typically refers to a remote service platform deployed by the vehicle manufacturer. Through the communication link between the vehicle and the cloud, the charging connection error signal can be transmitted to the cloud. Upon receiving this signal, the cloud platform can send a charging connection error alarm notification (such as push notifications, SMS alerts, or phone calls) to the user's mobile device (e.g., smartphones, smartwatches).
