[0049] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0050] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0051] The main solution of the embodiment of the present application is: obtain vehicle operation information, obtain the fast charging abnormality disabling flag and the fast charging enabling flag according to the vehicle operation information, and obtain the fast charging enabling signal according to the fast charging abnormality disabling flag and the fast charging enabling flag to perform fast charging operation.

[0052] Electric vehicles are gradually becoming the market's first choice due to their energy saving, high efficiency, low or zero emissions, low noise, fast acceleration, and low operating costs. As the electric vehicle market continues to expand, various OEMs have invested in research and development resources to meet the growing market demand. At present, electric vehicles are generally equipped with fast charging ports, which can quickly charge the power battery. While this fast charging function improves charging efficiency, it also brings certain risks. If the control is unreasonable, it may cause the electric vehicle to be unable to charge, or even damage the power battery. In extreme cases, it may cause a vehicle fire.

[0053] The present application provides a solution that analyzes vehicle operation information and accurately controls the fast charging enable signal, thereby improving charging efficiency and charging safety.

[0054] Based on this, the embodiment of the present application provides a vehicle fast charging control method, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the vehicle fast charging control method of the present application.

[0055] In this embodiment, the vehicle fast charging control method includes steps S10 to S30:

[0056] Step S10, obtaining vehicle operation information.

[0057] It should be noted that the vehicle operation information can obtain the first slow charge request flag, the second slow charge request flag, the slow charge gun connection flag, the shift lever position, the slow charge status, the user-set maximum allowed charging power, the user-set maximum allowed charging time, the communication loss flag, and the fault request flag. Specifically, the vehicle operation information can obtain the power battery management system (BMS, Battery Management System) slow charge request flag, the slow charge gun connection flag, the shift lever position, the vehicle charger (OBC, Onboard Charger) slow charge request flag, the telematics unit (Tbox) charging reservation status, the vehicle central control screen (IVI) user immediate charging request flag, the BMS slow charge status, the Tbox user stop charging request flag, the IVI user stop charging request flag, the IVI user set the maximum allowed charging power, the IVI user set the maximum allowed charging time, the slow charge time, the IVI user set the maximum allowed charging time, the BMS communication loss flag, the OBC communication loss flag, and the slow charge fault request flag.

[0058] Further, the BMS slow charge request flag indicates whether the BMS has initiated a slow charge request. The slow charge gun connection flag detects whether the charging gun is correctly connected to the vehicle's charging port. The shift lever position ensures that the vehicle is in the parking gear (P gear) to avoid charging while driving. The OBC slow charge request flag reflects whether the OBC is ready and requests slow charge. The Tbox charging reservation status shows whether the user has made a charging reservation through Tbox. The IVI user immediate charge request flag is a user's request to start charging immediately through IVI. The BMS slow charge status reports the current charging status of the power battery, such as whether charging has been completed. The Tbox user stop charging request flag is a user's request to stop charging through a mobile phone application. The IVI user stop charging request flag is a user's request to stop charging through IVI. The battery power reflects the current remaining power of the power battery. The maximum allowed charging power set by the IVI user is the charging upper limit set by the user through IVI. The slow charge time records the time that the charging process has lasted. The maximum allowed charging time set by the IVI user is the maximum charging time limit set by the user through IVI. The BMS communication loss flag indicates whether the communication between the BMS and the VCU is normal. The OBC communication loss flag indicates whether the communication between the OBC and the VCU is normal. The slow charge fault request flag reflects whether a fault occurs during the slow charge process and its type.

[0059] Vehicle operation information provides the control system with necessary data to help the system make correct charging decisions. By monitoring all aspects of the vehicle, potential safety hazards can be discovered in a timely manner to avoid accidents. Reasonable use of vehicle operation information can improve charging efficiency, meet the personalized needs of users, and enhance the overall user experience.

[0060] Step S20, obtaining a fast charging abnormality disabling flag and a fast charging enabling flag according to the vehicle operation information.

[0061] It should be noted that before obtaining the fast charging disabling flag and the fast charging enabling flag, it is necessary to obtain the fast charging demand flag according to the vehicle operation information.

[0062] Further, according to the vehicle operation information, the basic flag of the vehicle fast charging demand and the reset flag of the vehicle fast charging demand are obtained, and then the basic flag of the vehicle fast charging demand and the reset flag of the vehicle fast charging demand are judged to obtain the fast charging demand flag. Specifically, according to the vehicle operation information, the fast charging request flag, the fast charging gun connection flag, the shift lever position, the fast charging status, the battery power, the fast charging time, and the communication loss flag are obtained. The flags obtained above can be specifically expanded to BMS fast charging request flag, fast charging gun connection flag, shift lever position, Tbox charging reservation status, IVI user immediate charging request flag, BMS fast charging status, Tbox user stop charging request flag, IVI user stop charging request flag, IVI user set the maximum allowed charging power, IVI user set the maximum allowed charging time, fast charging time, IVI user set the maximum allowed charging time, BMS communication loss flag, and then obtain the preset allowed charging power and preset allowed charging time.

[0063] Further, when the fast charge request flag is the first preset value, the fast charge gun connection flag is the first preset value, and the shift lever position is the preset gear, the vehicle fast charge demand basic flag is determined to be the first preset value. When the fast charge request flag is the first preset value, the fast charge gun connection flag is the first preset value, and the shift lever position is the preset gear, any one of which is not satisfied, the vehicle fast charge demand basic flag is determined to be the second preset value. The first preset value is different from the second preset value. The first preset value is the value output by the flag position, and the second preset value is the value output by the flag reset. In this embodiment, the setting is represented by 1 and the reset is represented by 0. Specifically, when the BMS issues a fast charge request, it indicates that the battery needs to be charged, and the fast charge gun connection flag position ensures that the fast charge gun has been correctly connected to the vehicle, and the vehicle shift lever is in the "P gear". When these conditions are met at the same time, the fast charge demand basic flag will be set. When any of the above conditions is not met, the fast charge demand basic flag will be reset. The fast charge demand basic flag at this time is obtained according to the vehicle operation information.

[0064] Further, when at least one of the following conditions is satisfied: the fast charge request flag is the second preset value, the fast charge gun connection flag is the second preset value, the fast charge state is the preset state, the battery power exceeds the preset allowable charging power, the fast charge time exceeds the preset allowable charging time, and the communication loss flag is the second preset value, the vehicle fast charge demand reset flag is determined to be the first preset value; when any one of the following conditions is not satisfied: the fast charge request flag is the second preset value, the fast charge gun connection flag is the second preset value, the fast charge state is the preset state, the battery power exceeds the preset allowable charging power, the fast charge time exceeds the preset allowable charging time, and the communication loss flag is the second preset value, the vehicle fast charge demand reset flag is determined to be the second preset value. Specifically, the vehicle fast charge demand reset flag is used to determine when the fast charge process should be canceled. When the BMS fast charging request flag is reset, the fast charging gun connection flag is reset, the BMS fast charging status is "completed", the Tbox user stop charging request flag is set, the IVI user stop charging request flag is set, the battery power is equal to or exceeds the maximum allowable charging power set by the user, the fast charging time is equal to or exceeds the maximum allowable charging time set by the user, the BMS communication is lost, the fast charging fault request action is "prohibit fast charging", the Tbox reservation charging status is "there is a reservation, and the reservation end time has arrived", the Tbox charging reservation status is "there is a reservation, and the reservation time has not arrived", and the IVI user immediate charging request flag is reset, the vehicle fast charging demand reset flag is set, which means that the current fast charging demand should be canceled.

[0065] Furthermore, a judgment is made based on the status of the fast charge requirement basic flag and the fast charge requirement reset flag, thereby obtaining the fast charge requirement flag. Then, the fast charge abnormality disabling flag and the fast charge enabling flag are determined based on the fast charge requirement flag.

[0066] Step S30, obtaining a fast charging enable signal according to the fast charging abnormality disable flag and the fast charging enable flag to perform a fast charging operation.

[0067] It should be noted that the fast charging abnormal disabling flag and the fast charging enabling flag are two key logic judgment points, which together determine the final state of the fast charging enabling signal, thereby controlling the start or stop of the charging operation. The fast charging abnormal disabling flag is set based on a series of safety detection conditions, including but not limited to the fault signal reported by the BMS, the connection status of the fast charging gun, and the physical state of the vehicle. If any of these conditions is triggered, indicating that there is a charging safety hazard, the fast charging abnormal disabling flag will be set to prevent the start of the charging process. At the same time, the fast charging enabling flag is the result of an evaluation based on the current state of the vehicle and user needs. When the battery power of the vehicle is lower than the threshold set by the user, the user issues a charging request through IVI or Tbox, and the vehicle is in a safe charging state, the fast charging enabling flag will be set to indicate that the vehicle is ready for fast charging.

[0068] Furthermore, when the fast charging abnormality disabling flag is set to the first preset value, the fast charging enabling signal is obtained as charging abnormality. When the fast charging abnormality disabling flag is set to the first preset value, it means that the charging system has detected a potential abnormality or fault, which may include a battery failure detected by the BMS, a charging gun connection problem, or other safety-related alarm signals. In this case, the system will automatically set the fast charging enabling signal to "charging abnormality" to ensure that the charging process will not be started under conditions where there are safety hazards.

[0069] Further, when the fast charging abnormal disabling flag is the second preset value and the fast charging enabling flag is the first preset value, the fast charging enabling signal is obtained to disable fast charging. When the fast charging abnormal disabling flag is set to the second preset value, this usually means that although the system has not detected an immediate charging safety hazard, there are certain conditions that do not meet the requirements for starting charging, such as the battery is full or the user has canceled the charging request through IVI or Tbox. At the same time, if the fast charging enabling flag is also set to the first preset value, this may indicate that the vehicle is in a state where fast charging can be performed, but because the abnormal disabling flag has a higher priority, the system will comprehensively consider this information and ultimately decide not to enable fast charging.

[0070] Further, when the fast charging abnormality disabling flag is the second preset value and the fast charging enabling flag is the second preset value, the fast charging enabling signal is obtained to turn on fast charging. When the fast charging abnormality disabling flag is set to the second preset value, this indicates that the system has not detected any charging abnormality or fault, and the charging environment is in a safe state. At the same time, the fast charging enabling flag is also set to the second preset value, which usually means that all charging conditions are met, including that the battery power is lower than the preset threshold, the user has issued a charging request, and the vehicle is in an appropriate state. In this case, the system will combine these conditions and determine that it is suitable to turn on fast charging. Therefore, the fast charging enabling signal will be set to "turn on fast charging", allowing the charging process to proceed smoothly based on safety and user needs.

[0071] The present embodiment provides a vehicle fast charging control method, which obtains vehicle operation information, obtains a fast charging abnormality disabling flag and a fast charging enabling flag according to the vehicle operation information, obtains a fast charging enabling signal according to the fast charging abnormality disabling flag and the fast charging enabling flag, and performs a fast charging operation. By analyzing the vehicle operation information, the fast charging enabling signal is accurately controlled, thereby improving the charging efficiency and charging safety.

[0072] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can refer to the above introduction, and will not be repeated later. Figure 2 The vehicle fast charging control method step S20 also includes steps S201-S202:

[0073] Step S201, obtaining a fast charging requirement flag according to vehicle operation information.

[0074] It should be noted that in the vehicle fast charging control method, obtaining the fast charging demand flag according to the vehicle operation information is the basis for realizing intelligent charging management. This process involves a comprehensive assessment of the vehicle's current status, user needs and safety conditions to determine whether the fast charging program needs to be started.

[0075] Specifically, the system monitors key information provided by the BMS, including the battery's charge, voltage, temperature, etc., to assess the battery's charging needs and health. If the battery charge is lower than the charging threshold set by the user, this will become a factor in starting fast charging. Secondly, the system checks the physical state of the vehicle, including whether the charging gun is connected, whether the vehicle is in a parked state, whether the shift lever is in "P gear", etc., to ensure that the physical conditions for charging are met. In addition, the system will also evaluate the vehicle's electrical state, such as the communication status of the BMS, to ensure that information can be accurately transmitted during the charging process. Charging requests issued by users through IVI or Tbox are also important factors in determining fast charging needs. The user's charging preference settings, such as the maximum allowed charging power, charging time, etc., will be taken into account by the system to meet the user's personalized needs. Finally, the system will combine all this information and obtain the basic flag bit of the vehicle's fast charging demand and the reset flag bit of the vehicle's fast charging demand through a series of logical judgments. Then, according to the basic flag bit of the vehicle's fast charging demand and the reset flag bit of the vehicle's fast charging demand, the fast charging demand flag bit is determined. If all conditions are met, the fast charging demand flag bit will be set. If any of the conditions is not met, the fast charge requirement flag will be reset and fast charging will not be performed.

[0076] Further, when the basic flag bit that satisfies the vehicle's fast charging demand is the first preset value and the vehicle's fast charging demand reset flag bit is the second preset value, the fast charging demand flag bit is determined to be the first preset value. When the vehicle's fast charging demand basic flag bit is set to the first preset value, this indicates that the vehicle's battery power is lower than the charging threshold set by the user, and other basic conditions required for charging, such as the charging gun is connected and the vehicle is in a parked state, are met. At the same time, if the vehicle's fast charging demand reset flag bit is the second preset value, it means that no conditions for stopping charging are triggered, such as the user canceling the charging request or the battery is fully charged. In this case, the system determines that the fast charging demand flag bit is the first preset value, which confirms that the vehicle needs to be fast charged.

[0077] Further, when the vehicle fast charging demand basic flag is not the first preset value or the vehicle fast charging demand reset flag is not the second preset value, the fast charging demand flag is determined to be the second preset value. When the vehicle fast charging demand basic flag does not reach the first preset value, that is, the battery power of the vehicle has not yet fallen below the charging threshold set by the user, or the basic charging conditions such as the charging gun is not connected and the vehicle is not in a parked state are not met, the fast charging process will not start. Similarly, if the vehicle fast charging demand reset flag is not the second preset value, for example, the user has canceled the charging request or the battery is full, this indicates that the demand for fast charging no longer exists or no longer needs to continue. In either of these two situations, the system will determine that the fast charging demand flag is the second preset value, that is, fast charging will not be started.

[0078] Step S202, obtaining a fast charging abnormality disabling flag and a fast charging enabling flag according to the vehicle operation information and the fast charging demand flag.

[0079] It should be noted that, based on the vehicle's operating information, the system first evaluates whether the basic conditions for fast charging are met, such as battery power, charging gun connection status, whether the vehicle is in a parked state, etc., to determine the fast charging demand flag. If these conditions are met, the fast charging demand flag will indicate the charging demand. Subsequently, the system further analyzes whether there are any factors that may affect charging safety, such as battery failure, charging equipment abnormality, etc., to determine the fast charging abnormal disabling flag. If no abnormality is detected, the flag will not be set, indicating that the charging environment is safe. Conversely, if the system detects an abnormality, the abnormal disabling flag will be set to prevent the charging process. At the same time, if all conditions are normal and there are no abnormalities, the fast charging enabling flag will be set to allow the charging operation to proceed.

[0080] Furthermore, according to the vehicle operation information, a fault request flag is obtained. The fault request flag includes, but is not limited to, BMS high-voltage relay fault request action, BMS insulation fault flag, BMS high-voltage interlock fault flag, BMS thermal runaway alarm flag signal, and BMS high-voltage relay actual state. When the fault request flag is a first preset value, the fast charging abnormality disabling flag is determined to be a first preset value. When the fault request flag is set to the first preset value, this indicates that the vehicle's charging system has encountered a critical fault or abnormality, such as when the BMS high-voltage relay fault request action is "disconnect relay", which may pose a direct threat to charging safety or cause damage to the charging equipment. In this case, the system will determine that the fast charging abnormality disabling flag is the first preset value, which means that the system will immediately prohibit the charging operation to prevent the fault from further deteriorating.

[0081] Furthermore, when the fault request flag is the second preset value, the fast charging abnormality disabling flag is determined to be the second preset value. When the fault request flag is set to the second preset value, this generally indicates that the vehicle's charging system has detected that there is no fault or abnormality. For example, when the actual state of the BMS high-voltage relay is "closed", the system can choose to continue the charging operation while monitoring and recording these abnormal conditions for further diagnosis and processing.

[0082] Further, when the fast charging abnormality disabling flag is the second preset value and the fast charging requirement flag is the first preset value, the fast charging enabling flag is determined to be the first preset value. When the fast charging abnormality disabling flag is set to the second preset value, this indicates that the system has not detected any critical faults or abnormalities, the charging environment is in a safe state, and there is no immediate safety risk. At the same time, if the fast charging requirement flag is the first preset value, this indicates that the vehicle does need to be fast charged based on the vehicle's battery power, user settings, and other charging conditions. When these two conditions are met at the same time, the system will determine that the fast charging enabling flag is the first preset value, that is, the charging process is allowed to start.

[0083] Further, when the fast charging abnormality disabling flag is not the second preset value or the fast charging requirement flag is not the first preset value, the fast charging enabling flag is determined to be the second preset value. If the fast charging abnormality disabling flag is not the second preset value, that is, the system has detected certain faults or abnormal conditions, which may include battery problems, charging equipment failures or other safety hazards. At this time, the system will set the fast charging enabling flag to the second preset value to prevent the charging process and ensure safety. Similarly, if the fast charging requirement flag is not the first preset value, this indicates that the vehicle does not currently need to be charged, possibly because the battery is fully charged or the user has not issued a charging request. In either of these two cases, the fast charging enabling flag will be set to the second preset value, which means that the charging operation will not be started, thereby avoiding charging in inappropriate or unsafe conditions.

[0084] This embodiment obtains the fast charging requirement flag according to the vehicle operation information, and obtains the fast charging abnormality disabling flag and the fast charging enabling flag according to the vehicle operation information and the fast charging requirement flag. Through real-time monitoring, charging safety is ensured, charging efficiency is optimized, and user experience is improved.
