However, various charging faults can occur during fast charging, and troubleshooting these faults has become an important research topic in the industry.

[0003] Currently, with existing technologies, users mainly rely on their own experience or consult professional technical advisors, and then follow the instructions to troubleshoot from the fast charging station to the charger and then to the electric vehicle in order to solve fast charging problems.

[0004] However, the inventors have discovered that the existing technology has at least the following technical problems: relying on human experience or advice obtained after consulting professional technicians to troubleshoot electric vehicle fast charging faults still has the disadvantages of low efficiency and long time consumption. Summary of the Invention

[0005] This application provides a charging system, a charging fault handling method, an apparatus, a device, and a storage medium to solve the problem of long fault handling time caused by low efficiency in the fast charging fault handling process.

[0021] In one possible implementation, after determining the inspection feedback information based on the inspection request information, the method further includes: if the inspection feedback information meets the conditions for canceling the inspection, then controlling the TBOX to go into sleep mode.

[0022] In one possible implementation, after obtaining the power system feedback information via the CAN bus, the method further includes: if the power system feedback information meets the normal conditions of the power system, generating and displaying charging source inspection information.

[0023] Thirdly, this application provides a charging fault handling device, applied to the vehicle terminal of the charging system as described in the first aspect, the device comprising:

[0024] The acquisition module is used to acquire the fast charging wake-up signal output by the positive wake-up source pin of the fast charging pile;

[0025] The TBOX control module is used to perform a wake-up operation on the TBOX according to the fast charging wake-up signal, and to obtain the voltage value change information of the second activation pin of the TBOX in real time.

[0026] The relay status determination module is used to determine the relay operating status of the fast charging wake-up relay based on the voltage value change information.

[0028] The inspection feedback module is used to determine inspection feedback information based on the inspection request information;

[0029] The control module is used to control the TBOX to wake up the CAN bus and obtain the power system feedback information through the CAN bus if the inspection feedback information meets the confirmation inspection conditions.

[0035] Fifthly, this application provides a computer-readable storage medium storing computer-executable instructions, which, when executed by a processor, implement the charging fault handling method described in the second aspect.

[0036] The charging system, charging fault handling method, apparatus, equipment, and storage medium provided in this application utilize a five-pin relay as a fast-charging wake-up relay in the charging system. The fault type (fast-charging relay malfunction or other fault) is determined by the output voltage changes of the fast-charging wake-up relay's pins. When a vehicle is connected to a fast-charging station, the vehicle's infotainment system receives the fast-charging wake-up signal from the positive wake-up source pin of the fast-charging station. Based on this signal, a wake-up operation is performed on the TBOX (Tank Box). The system continuously monitors the voltage changes of the second activation pin B2 of the TBOX and determines the relay's operating state based on these voltage changes. If the relay is in a conducting state, it indicates that the fast-charging wake-up relay is functioning correctly. If the device is fault-free, further inspection of the power system is required. Simultaneously, an inspection request is generated. If the inspection feedback information, based on the request, meets the confirmation inspection conditions, the TBOX is controlled to wake up the CAN bus. After waking up the bus network, the power system feedback information is obtained via the CAN bus. If the power system feedback information meets the power system fault conditions, it indicates that the charging fault is caused by a power system malfunction. At this point, power system repair information is generated and displayed to the user, prompting them to handle the fast charging fault according to the repair information. This provides users with quick fault analysis results for fast charging fault handling, improving troubleshooting efficiency and reducing troubleshooting time. Attached Figure Description

[0045] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0046] Currently, with the increasing popularity of electric vehicles, users have higher and higher requirements for vehicle charging performance. When a vehicle malfunctions during fast charging, users can only rely on their own experience or the advice of professional technicians to troubleshoot the problem. The inventors have discovered that in existing technologies, electric vehicles mainly use 12V and 24V fast charging stations. When users use these charging stations to fast charge their vehicles, there are three main types of problems: incorrect selection of the fast charging wake-up relay, relay failure, or incorrect selection of the charging station voltage.

[0047] Figure 1 This is a connection diagram illustrating the fast charging pile control relay energizing for fast charging wake-up according to an embodiment of this application.

[0048] Figure 2 This is a connection diagram of a fast charging pile provided in this application embodiment when it is directly activated by hard-wire fast charging.

[0049] like Figure 1 As shown, if a fast charging fault is detected, relying solely on user troubleshooting and subsequent fast charging wake-up can cause the output voltage to directly impact the electric vehicle's Battery Management System (BMS). While this achieves fast charging wake-up, it also carries the risk of damaging the battery chips and the BMS. Therefore, modern fast charging wake-up methods often employ... Figure 2 The fast charging wake-up method shown.

[0050] like Figure 2As shown, a four-pin relay is added between the fast charging station and the BMS. The fast charging station first supplies power to the relay to control the fast charging wake-up relay to activate and wake up the BMS. However, since the fast charging wake-up relay cannot be directly exposed and requires a high level of expertise from troubleshooting personnel, it increases the difficulty of troubleshooting for users without professional technical knowledge when a fast charging fault is discovered, affecting the efficiency of troubleshooting and increasing the time spent on troubleshooting.

[0051] To address the aforementioned technical problems, this application provides the following technical concept: A fast-charging wake-up relay with five pins is used, and the voltage changes of the relay pins are used to determine whether the fast-charging wake-up relay is in a conducting or disconnected state. This allows for a determination of whether the fast-charging fault is related to a fault in the fast-charging wake-up relay. When the fast-charging wake-up relay is working normally, a remote information processing controller is used to wake up the vehicle controller local area network (CAN bus) to further determine if there is a powertrain fault. This provides users with rapid fault analysis results for fast-charging fault handling, improving fault diagnosis efficiency and reducing fault diagnosis time.

[0052] Figure 3 This is a schematic diagram illustrating an application scenario of the charging fault handling method provided in the embodiments of this application, such as... Figure 3 As shown, it includes: fast charging station 301 and vehicle 302.

[0053] The fast-charging pile 301 supplies power to the electric vehicle 302. The fast-charging pile 301 can be a 12V or 24V fast-charging pile. A relay is installed in the fast-charging pile 301 to protect the fast-charging circuit. The vehicle 302 can be a pure electric vehicle or a hybrid vehicle, or any other vehicle capable of using electrical energy. The vehicle 302 is equipped with a Battery Management System (BMC) and a vehicle-mounted infotainment system. In the vehicle 302, the BMC protects the battery cells and battery pack from damage, ensuring the battery operates within a safe voltage and temperature range and maintains safe battery operation. The vehicle-mounted infotainment system allows users to view fault information and troubleshooting results, as well as select corresponding options to enable fast-charging wake-up.

[0054] Figure 4 This is a schematic diagram of the connection structure of the charging system provided in an embodiment of this application.

[0055] like Figure 4 As shown, the charging system is deployed in, for example Figure 3In the vehicle 302 shown, the charging system includes: a fast-charging wake-up relay, a telematics controller TBOX, and a vehicle-mounted terminal; the control coil input pin 85 of the fast-charging wake-up relay and the first activation pin B1 of the TBOX are both connected to the positive wake-up source pin A+ of the fast-charging charging pile; the control coil output pin 86 of the fast-charging wake-up relay is connected to the negative wake-up source pin A- of the fast-charging charging pile; the total power input pin 30 of the fast-charging wake-up relay is connected to the positive terminal KL30 of the vehicle power supply; the normally closed pin 87b of the fast-charging wake-up relay is connected to the second activation pin B2 of the TBOX; and the normally open pin 87a of the fast-charging wake-up relay is connected to the fast-charging wake-up interface of the battery management system (BMS); the TBOX and the vehicle-mounted terminal are connected via the vehicle controller local area network (CAN bus).

[0056] The vehicle-mounted system is used for: acquiring the fast-charging wake-up signal output from the positive wake-up source pin A+ of the fast-charging pile; performing a wake-up operation on the TBOX based on the fast-charging wake-up signal, and acquiring the voltage change information of the second activation pin B2 of the TBOX in real time; determining the relay operating state of the fast-charging wake-up relay based on the voltage change information; generating a check request information if the fast-charging wake-up relay is in the on state; determining the check feedback information based on the check request information; controlling the TBOX to wake up the CAN bus if the check feedback information meets the confirmation check conditions, and acquiring the powertrain feedback information through the CAN bus; generating powertrain maintenance information if the powertrain maintenance information meets the powertrain fault conditions, and displaying the powertrain maintenance information to prompt the user to handle the fast-charging fault according to the powertrain maintenance information.

[0057] The following are the specific steps and principles of the charging fault handling method when the vehicle-mounted terminal is the executing entity.

[0058] Figure 5 This is a flowchart illustrating the charging fault handling method provided in an embodiment of this application.

[0059] The entity executing the fault handling method provided in this embodiment can be Figure 4 The vehicle-mounted terminal in the vehicle-mounted system shown in the embodiment can also be other computer-related devices; this embodiment is not particularly limited. Figure 5 As shown, the method includes:

[0060] S501: Obtain the fast charging wake-up signal output from the positive wake-up source pin of the fast charging pile.

[0061] like Figure 4 and Figure 5As shown in this embodiment, the fast charging wake-up signal output by the positive wake-up source pin of the fast charging pile indicates that when the car is fast charging, the fast charging pile will output current through the positive wake-up source pin and input it to the first activation pin B1 of TBOX through a hard wire. This is the signal generated when the entire fast charging system is woken up.

[0062] S502: Performs a wake-up operation on the TBOX according to the fast charging wake-up signal, and obtains the voltage value change information of the second activation pin of the TBOX in real time.

[0063] In this embodiment, when the TBOX detects the current input to the first activation pin B1, the entire charging system is activated, and the TBOX is also activated. At this time, the voltage change information of the second activation pin B2 of the TBOX can be detected by electronic components with voltage detection function, such as a voltage sensor. The voltage change of the second activation pin B2 can be used as a basis for determining whether the relay is properly engaged.

[0064] S503: Determine the relay operating status of the fast charging wake-up relay based on voltage value change information.

[0065] In this embodiment, the voltage change information can be that the voltage value stabilizes at a specific value, such as 12V or 24V. Alternatively, the voltage change information can be that the voltage value changes from a value to 0V, for example, from 12V or 24V to 0V. The relay operating state of the fast charging wake-up relay can be either in an on state or an off state.

[0066] In an optional embodiment of this application, step S503 may also involve determining whether the voltage of the second activation pin B2 of the TBOX is 12V or 24V based on the voltage change. If it is "yes", it is in a conducting state; otherwise, it is in a disconnected state, indicating that the fast charging wake-up relay may be faulty or the charging voltage selection may be incorrect.

[0067] Based on the above embodiments, in an optional embodiment of this application, after step S503, the method further includes:

[0068] S503-a: If the relay is in the off state, generate and display charging voltage selection information.

[0069] In this embodiment, the relay being in the off state indicates that the voltage of the second activation pin B2 of TBOX is 0V. At this time, it is necessary to determine whether the charging pile voltage has been correctly selected. The charging voltage selection information can be a prompt to the user to check whether a suitable charging pile voltage has been selected. For example, this charging voltage selection information can be the audio and text content displayed in the IPK of the instrument cluster, such as "Please confirm whether to select 12V charging" or "Please confirm whether to select 24V charging."

[0070] S503-b: If the charging voltage feedback information meets the relay fault conditions, then the relay fault handling information is generated and displayed.

[0071] In this embodiment, the relay fault condition indicates that the charging voltage feedback information confirms that the charging pile voltage selected by the user is correct. The relay fault handling information can be a prompt to the user that the fast charging wake-up relay may be faulty and requires repair. For example, the relay fault handling system could be the voice and text content displayed in the instrument cluster IPK stating "The relay may be faulty; please contact a professional for troubleshooting" in a pop-up window.

[0072] In an optional embodiment of this application, after S503-a, the method further includes: if the charging voltage feedback information meets the normal conditions of the relay, then controlling TBOX to enter sleep mode.

[0073] In this embodiment, the charging voltage feedback information satisfying the relay's normal conditions means that the user has selected the correct charging voltage.

[0074] In an optional embodiment of this application, after generating and displaying the charging voltage selection information in step S503-a, the method further includes: obtaining the correct voltage selection operation and operation duration of the user for the charging voltage selection information; if the charging voltage feedback information meets the relay fault condition or the operation duration is greater than the preset duration threshold, then controlling the TBOX to go into sleep mode.

[0075] For example, if a confirmation is selected in the pop-up window, or if no selection is made within a preset fixed time period (e.g., more than 30 seconds), the TBOX will enter sleep mode, indicating that troubleshooting is not required at this time.

[0076] S504: If the relay is in the ON state, a check request message is generated.

[0077] In this embodiment, if the relay is in the ON state, it means that the main power input pin 30 of the fast charging wake-up relay is still connected to the normally closed pin 87b, and the relay has not changed. Therefore, it can be seen that the fast charging wake-up relay has current input but is not properly engaged. In this case, the troubleshooting direction for the charging fault could be an incorrect charging pile voltage selection or an incorrect fast charging wake-up relay selection. The inspection request information can be at least one of the text or voice prompts reminding the user to check the above troubleshooting directions. For example, the inspection request information could be "Hello, do you need to perform an inspection?"

[0078] S505: Determine the inspection feedback information based on the inspection request information.

[0079] In this embodiment, the inspection feedback information may be generated in response to the user's inspection selection operation based on the inspection request information. Alternatively, the inspection feedback information may be generated automatically by the vehicle-mounted system based on the inspection request information. Furthermore, the inspection feedback information may be automatically generated by the vehicle-mounted system if it does not receive feedback from the user after an inspection or after an automatic inspection within a pre-set time period.

[0080] For example, the user's inspection action in response to the inspection request can be an instruction generated by the user performing a corresponding operation on the vehicle's infotainment system. This instruction can be a gesture instruction or a voice control instruction. The inspection feedback information can be: confirmation or cancellation.

[0081] In an optional embodiment of this application, after step S505, the method further includes:

[0082] S505a: If the inspection feedback information meets the conditions for canceling the inspection, control the TBOX to go into sleep mode.

[0083] In this embodiment, the conditions for canceling the check can be that the user selects the cancel option in response to the check request information or that no selection operation is performed within a preset fixed time period. For example, the "cancel" button is selected by default after a fixed time period of 30 seconds.

[0084] S506: If the inspection feedback information meets the confirmation inspection conditions, control the TBOX to wake up the CAN bus and obtain the power system feedback information through the CAN bus.

[0085] In this embodiment, the check feedback information meets the confirmation check conditions, where the confirmation check conditions can be feedback opinions that the user agrees with, such as: the user selects the "confirm" option.

[0086] In an optional embodiment of this application, the CAN bus stores power system operating status information issued by the energy management system (PMS). Accordingly, step S506 includes:

[0087] S506a: Controls the TBOX to execute pre-stored management messages and wakes up the CAN bus network.

[0088] In this embodiment, the pre-stored management message refers to the message used for managing and controlling communication in the communication protocol or network. Wake up the CAN bus network refers to establishing a connection between the TBOX and the vehicle's infotainment system so that other devices on the vehicle can perform corresponding operations based on received instructions, such as starting the engine.

[0089] S506b: Obtains power system feedback information by detecting power system fault signals in the power system operating status signals sent by the energy management system (PMS) on the CAN bus.

[0090] In this embodiment, the power system operating status signal issued by the energy management system may include signals indicating power system malfunction or normal operation. Power system feedback information can be obtained through text recognition methods to detect whether the power system operating status information issued by the PMS contains any content indicating a power system malfunction.

[0091] The next step is to determine whether there is a powertrain malfunction, as follows:

[0092] S507: If the power system feedback information meets the power system fault conditions, then power system repair information is generated and displayed to prompt the user to handle the fast charging fault according to the power system repair information.

[0093] In this embodiment, the power system fault condition refers to the detection of a power system fault. The power system maintenance information can be at least one of the following: a prompt message for the user, such as an audio message or a pop-up text message. For example, the power system maintenance information can be an audio message and a pop-up message displayed on the instrument cluster IPK that reads "Power system fault, please contact maintenance personnel in time".

[0094] In an optional embodiment of this application, after obtaining the power system feedback information via the CAN bus in step S506, the method further includes:

[0095] Step 508: If the power system feedback information indicates that the power system meets normal conditions, then generate and display the charging source check information.

[0096] In this embodiment, the normal condition of the power system refers to the absence of a power system fault. The charging source check information can be used to prompt the user to check the fault troubleshooting information related to the charging source. For example, the charging source check information can be an audio and pop-up reminder displayed on the instrument cluster IPK that says "No fault found, please check the charging pile or reset the charging settings".

[0097] In summary, the charging fault handling method provided in this application, when a car is connected to a fast charging pile for charging, after the vehicle's terminal obtains the fast charging wake-up signal from the positive wake-up source pin of the fast charging pile, it performs a wake-up operation on the TBOX according to the fast charging wake-up signal, obtains the voltage value change information of the second activation pin B2 of the TBOX in real time, and determines the relay working state based on the voltage value change information. If the relay working state is in the conducting state, it indicates that the fast charging wake-up relay is not faulty, and it is necessary to further check whether the power system is faulty. At the same time, an inspection request information is generated. If the inspection feedback information determined according to the inspection request information meets the confirmation inspection conditions, then... The TBOX is controlled to wake up the CAN bus. After waking up the bus network, the power system feedback information is obtained through the CAN bus. If the power system feedback information meets the power system fault conditions, it indicates that the charging fault is caused by the power system fault. At this time, power system maintenance information is generated and displayed to the user to prompt the user to handle the fast charging fault according to the power system maintenance information. This application uses a five-pin relay as a fast charging wake-up relay, and infers whether the fast charging relay is faulty or other faults by the output voltage change of the pins of the fast charging wake-up relay. This provides users with quick fault analysis results for fast charging fault handling, improves fault diagnosis efficiency, and reduces fault diagnosis time.
