[0053] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0054] The technical problem to be solved by the embodiments of the present application is that, for pure electric vehicles and plug-in hybrid electric vehicles, the plug-in charging function is indispensable. Charging by plugging in a gun can increase the vehicle's range. At the same time, since there are many safety hazards in the transmission of electric energy, it is necessary to comprehensively consider various complex situations when entering or exiting the charging function to avoid accidental exiting charging or not exiting charging in time. Therefore, it is necessary to effectively coordinate the vehicle charging function and intuitively observe the charging results to facilitate after-sales maintenance. When an unexpected situation occurs, resulting in exiting charging, the relevant signal status at the time of exiting is automatically stored, which is conducive to later fixed-point maintenance.

[0055] Compared with the prior art, the embodiments of the present application are more comprehensive, and the related conditions are listed, and different conditions are distinguished according to different vehicle states. At the same time, an independent calibration quantity is configured for each condition, and specific combinations can be made according to the platform and project configuration, which is more flexible.

[0056] Specifically, the embodiment of the present application provides a new energy vehicle charging management method, which is implemented by a vehicle controller, such as Figure 1 As shown, the method includes steps S101, S102, S103 and S104, wherein:

[0057] In step S101 , when the insertion of the charging gun is detected, it is determined whether the charging condition is met.

[0058] In step S102, when it is determined that the charging condition is met, charging is started and the charging process is monitored to see whether it is abnormally terminated.

[0059] In step S103, when it is monitored that the charging process is abnormally terminated, the abnormal charging reason, charging duration and current time are obtained.

[0060] In step S104, the abnormal charging reason, charging duration and current time are stored correspondingly.

[0061] In some optional embodiments, when the insertion of the charging gun is detected, determining whether the charging condition is met includes:

[0062] When the insertion of the charging gun is detected, the vehicle power-on mode, current status of the vehicle and vehicle model identification are obtained.

[0063] The corresponding signal array set and calibration array set are obtained according to the vehicle power-on mode. The signal array set consists of m bits, including n signal bits and blank bits except the n signal bits. The bit values ​​of the n signal bits in the signal array set are determined according to the current state of the vehicle. The calibration array set consists of m bits, including n calibration bits and blank bits except the n calibration bits. The bit values ​​of the n calibration bits in the calibration array set are determined according to the vehicle model identification, where n≤m.

[0064] Perform a logical AND operation on the signal array set and the calibration array set to obtain the total number of bit values.

[0065] Determine whether the total number of bit values ​​is greater than or equal to a preset value.

[0066] When it is determined that the total number of bit values ​​is greater than or equal to the preset value, it is determined that the charging condition is met.

[0067] In some optional embodiments, different vehicle power-on modes correspond to different signal array sets, and the total number of m bits in different signal array sets is the same, but the total number of n signal bits is different.

[0068] Different vehicle power-on modes correspond to different calibration array sets, and the total number of m bits in different calibration array sets is the same, but the total number of n calibration bits is different.

[0069] In some optional embodiments, the method further comprises:

[0070] When it is determined that the charging conditions are met, charging starts and the charging time is recorded from zero.

[0071] When the charging process is detected to be abnormally terminated, the abnormal charging reason, charging duration and current time are obtained, including:

[0072] When it is detected that the charging process is abnormally terminated, a signal array set is obtained, and the signal array set is used as the cause of the abnormal charging.

[0073] In some optional embodiments, storing the abnormal charging reason, the charging duration, and the current time in correspondence includes:

[0074] The corresponding abnormal charging reason, charging time and current time are stored as a set of abnormal data.

[0075] In some optional embodiments, the method further comprises:

[0076] When the number of groups of stored abnormal data exceeds the preset number of groups, the first group of stored abnormal data is deleted.

[0077] By adopting the new energy vehicle charging management method provided by the present application, when it is detected that the charging gun is inserted and the charging conditions are met, it means that charging can be carried out. At this time, charging starts and the charging process is monitored in real time to see whether there is an abnormal termination. When it is detected that the charging process is abnormally terminated, it is necessary to collect the reasons for the abnormal charging termination for subsequent corresponding summary and corresponding improvement. At this time, the reasons for abnormal charging, charging time and current time are obtained, and the reasons for abnormal charging, charging time and current time are stored accordingly, so as to realize efficient and flexible unified management and statistics of charging.

[0078] The present application embodiment also provides another new energy vehicle charging management method, which is implemented by a vehicle controller, such as Figure 2 As shown, the method includes steps S201, S202, S203, S204 and S205, wherein:

[0079] In step S201 , when the insertion of the charging gun is detected, it is determined whether the charging condition is met.

[0080] In some optional embodiments, the embodiments of the present application use an array set to determine whether the charging condition is met, thereby achieving the customizability and flexibility of the charging condition determination process. A program can be established in a programming manner, and the establishment of the array set can be implemented through the program. Specifically, when the insertion of the charging gun is detected, determining whether the charging condition is met includes:

[0081] When the insertion of the charging gun is detected, the vehicle power-on mode, current status of the vehicle and vehicle model identification are obtained.

[0082] It is understood that the vehicle power-on mode includes OFF mode, ACC mode, ON mode and READY mode. The current status of the vehicle includes the charging gun status, battery charging request status, OBC fault status, DCDC fault status, intelligent charging process status, remote start process status, external discharge process status, collision-related fault status, circuit fault status, battery power status, vehicle speed status, communication fault status, and TBOX fault status. The vehicle model identification can be represented by the frame number or an independent vehicle model identification.

[0083] After obtaining the vehicle power-on mode, it is necessary to obtain the corresponding signal array set and calibration array set according to the vehicle power-on mode. The signal array set consists of m bits, including n signal bits and blank bits except the n signal bits. The bit values ​​of the n signal bits in the signal array set are determined according to the current state of the vehicle. The calibration array set consists of m bits, including n calibration bits and blank bits except the n calibration bits. The bit values ​​of the n calibration bits in the calibration array set are determined according to the vehicle model identification, where n≤m.

[0084] In some optional embodiments, different vehicle power-on modes correspond to different signal array sets, and the total number of m bits in different signal array sets is the same, but the total number of n signal bits is different.

[0085] Different vehicle power-on modes correspond to different calibration array sets, and the total number of m bits in different calibration array sets is the same, but the total number of n calibration bits is different.

[0086] In some optional embodiments, the signal array set and the calibration array set corresponding to the vehicle power-on mode may be pre-calibrated and stored, such as Figure 3 As shown, m is 16. In other words, the signal array set and the calibration array set are both a column array set consisting of 16 bits, that is, a two-dimensional array type variable. The signal array set corresponding to the OFF mode is A1, the signal array set corresponding to the ACC mode is A2, the signal array set corresponding to the ON mode is A3, and the signal array set corresponding to the READY mode is A4. For different vehicle power-on modes (OFF mode, ACC mode, ON mode, and READY mode), the number of n signal bits included in the m bits of the corresponding signal array set is different. In other words, the number of signal bits included in the 16 bits of the signal array set corresponding to different vehicle power-on modes (OFF mode, ACC mode, ON mode, and READY mode) is different.

[0087] If the number of conditions associated with charging exceeds 16, the specification of the array set may be expanded accordingly, such as setting an array set consisting of 32 or 64 bits.

[0088] If the vehicle power-on mode has other modes besides the OFF mode, the ACC mode, the ON mode and the READY mode, more column array sets may be set, and the number of columns of the array set is consistent with the number of vehicle power-on modes.

[0089] For example, if Figure 3As shown, the 16 bits of the signal array set A1 include 12 signal bits, and the 12 signal bits are Num0, Num1, Num2, Num3, Num4, Num5, Num6, Num7, Num8, Num9, Num11 and Num12, and except for these 12 signal bits, all the 16 bits are blank bits.

[0090] Similarly, the 16 bits of the signal array set A2 include 10 signal bits, which are Num0, Num1, Num2, Num3, Num6, Num7, Num8, Num9, Num11 and Num12, and all the 16 bits except these 10 signal bits are blank bits.

[0091] The 16 bits of the signal array set A3 include 9 signal bits, which are Num0, Num1, Num2, Num3, Num6, Num7, Num8, Num9 and Num11, and all the 16 bits except these 9 signal bits are blank bits.

[0092] The 16 bits of the signal array set A4 include 10 signal bits, and the 10 signal bits are Num0, Num1, Num2, Num3, Num6, Num7, Num8, Num9, Num10 and Num11, and the 16 bits except these 10 signal bits are blank bits.

[0093] The bit values ​​of the n signal bits in the signal array set are determined according to the current state of the vehicle. In some optional embodiments, the bit values ​​of Num0, Num1, Num2, Num3, Num4, Num5, Num6, Num7, Num8, Num9, Num10, Num11 and Num12 are respectively determined according to the charging gun status, battery charging request status, OBC fault status, DCDC fault status, intelligent charging process status, remote start process status, external discharge process status, collision-related fault status, circuit fault status, battery power status, vehicle speed status, communication fault status, and TBOX fault status. Specifically, when the charging gun status indicates that the charging gun has been inserted, the bit value of Num0 is 1; when the battery charging request status indicates that there is a request, the bit value of Num 1 is 1; when the OBC fault status indicates that there is no fault, the bit value of Num 2 is 1; when the DCDC fault status indicates that there is no fault, the bit value of Num 3 is 1; when the intelligent charging process status indicates that it is not in process, the bit value of Num 4 is 1; when the remote start process status indicates that it is not in process, the bit value of Num 5 is 1; when the external discharge process status indicates that it is not in process, the bit value of Num 6 is 1; when the collision-related fault status indicates that there is no fault, the bit value of Num 7 is 1; when the circuit fault status indicates that there is no fault, the bit value of Num 8 is 1; when the battery power status indicates that the battery SOC is within the threshold range, the bit value of Num 9 is 1; when the vehicle speed status indicates that the vehicle speed is lower than the threshold, the bit value of Num 10 is 1; when the communication fault status indicates that there is no CAN communication fault, Num The bit value of 11 is 1. When the TBOX fault status indicates no fault, the bit value of Num12 is 1. Otherwise, the bit values ​​of Num0, Num1, Num2, Num3, Num4, Num5, Num6, Num7, Num8, Num9, Num10, Num11 and Num12 are 0.

[0094] In some optional embodiments, when the insertion of the charging gun is detected, the signal array set may be initialized first, and the bit values ​​of all bits in the signal array set may be set to 0. After a preset time has passed, the bit values ​​of the n signal bits in the signal array set are determined according to the current state of the vehicle. The preset time may be 2 seconds.

[0095] In summary, the bit values ​​of the n signal bits in the signal array set can be determined according to the current state of the vehicle, so as to further determine whether the vehicle meets the charging conditions.

[0096] For all vehicle models, four fixed signal array sets corresponding to the four vehicle power-on modes can be set to facilitate unified management and avoid the need to frequently change and customize the signal array sets due to different vehicle models and charging conditions, which increases the difficulty of charging management.

[0097] The same logic applies to signal array collections, such as Figure 3 As shown, the calibration array set corresponding to the OFF mode is B1, the calibration array set corresponding to the ACC mode is B2, the calibration array set corresponding to the ON mode is B3, and the calibration array set corresponding to the READY mode is B4. For different vehicle power-on modes (OFF mode, ACC mode, ON mode, and READY mode), the number of n calibration bits included in the m bits of the corresponding calibration array set is different. In other words, the number of calibration bits included in the 16 bits of the calibration array set corresponding to different vehicle power-on modes (OFF mode, ACC mode, ON mode, and READY mode) is different.

[0098] For example, if Figure 3 As shown, the 16 bits of the calibration array set B1 include 12 calibration bits, and the positions of the 12 calibration bits correspond to the positions of the 12 signal bits corresponding to the signal array set A1, and the 16 bits except the 12 calibration bits are all blank bits.

[0099] Similarly, the 16 bits of the calibration array set B2 include 10 calibration bits, and the positions of the 10 calibration bits correspond to the positions of the 10 signal bits corresponding to the signal array set A2, and the 16 bits except the 10 calibration bits are all blank bits.

[0100] The 16 bits of the calibration array set B3 include 9 calibration bits, and the positions of the 9 calibration bits correspond to the positions of the 9 signal bits corresponding to the signal array set A3. Except for the 9 calibration bits, all the 16 bits are blank bits.

[0101] The 16 bits of the calibration array set B4 include 10 calibration bits, and the positions of the 10 calibration bits correspond to the positions of the 10 signal bits corresponding to the signal array set A4, and the 16 bits except the 10 calibration bits are all blank bits.

[0102] After obtaining the corresponding signal array set and calibration array set according to the vehicle power-on mode, a logical AND operation is further performed on the signal array set and the calibration array set to obtain the total number of bit values. Performing a logical AND operation on the signal array set and the calibration array set refers to performing a logical AND operation on the signal bits in the signal array set and the corresponding calibration bits in the calibration array set, respectively, and summing the results of the logical AND operation.

[0103] It can be understood that the bit values ​​of the n calibration positions in the calibration array set are determined according to the vehicle model identification. For different vehicle models, although the four signal array sets corresponding to the four vehicle power-on modes are fixed, different calibration array sets can be customized according to different vehicle models. If a certain vehicle model does not need to consider one or some specific charging conditions, in other words, the bit values ​​of the n signal bits in the signal array set do not need to be considered in full, and there are some signal bits whose bit values ​​do not need to be considered, then the bit values ​​of the calibration bits corresponding to these signal bits can be directly set to 0 in the calibration array set, and the bit values ​​of the calibration bits corresponding to other signal bits can be set to 1, so that when the signal array set and the calibration array set are subsequently logically ANDed, no matter whether the bit value of the corresponding signal bit is 0 or 1, the bit value obtained after the logical AND operation of the calibration bit with a bit value of 0 and the bit value of the corresponding signal bit is always 0, and the bit values ​​of this part of the signal bits are successfully set to zero, and the bit values ​​of this part of the signal bits are not considered, which meets the situation that the signal array set needs to be changed and customized due to different vehicle models and different charging conditions. On the basis of reducing the difficulty of charging management, the charging management can be customized, and the flexibility of charging management is improved.

[0104] like Figure 3 As shown, if a vehicle model does not need to consider the external discharge process, the bit value of the calibration bit in the calibration array set and corresponding to Num6 in the signal array set is directly set to 0, and the value obtained after the logical AND operation of the calibration bit in the calibration array set and corresponding to signal bit Num6 in the signal array set and signal bit Num6 in the signal array set is always 0.

[0105] The number of signal bits that need to be considered in the signal array set corresponding to each vehicle power-on mode is equal to the number of calibration bits with bit values ​​of 1 in the calibration array set. This feature can be used to verify the accuracy of the calibration array set.

[0106] After the total number of bits is obtained, it is further determined whether the total number of bit values ​​is greater than or equal to a preset value.

[0107] When it is determined that the total number of bit values ​​is greater than or equal to the preset value, it is determined that the charging condition is met.

[0108] It can be understood that the vehicle power-on mode can only be in one of the OFF mode, ACC mode, ON mode and READY mode. Therefore, as long as it is determined that the total number of bit values ​​corresponding to one of the OFF mode, ACC mode, ON mode and READY mode is greater than or equal to the preset value, it means that the charging conditions are met.

[0109] Different vehicle power-on modes may correspond to different preset values. For example, the preset value corresponding to the OFF mode may be 12, the preset value corresponding to the ACC mode may be 10, the preset value corresponding to the ON mode may be 9, and the preset value corresponding to the READY mode may be 10. If a vehicle model does not need to consider one or some specific charging conditions, in other words, the bit values ​​of the n signal bits in the signal array set do not need to be considered in full, and the bit values ​​of some signal bits do not need to be considered, then the value of the preset value may be reduced accordingly.

[0110] In step S202, when it is determined that the charging condition is met, charging is started and the charging process is monitored to see whether it is abnormally terminated.

[0111] In some optional embodiments, the method further comprises:

[0112] When it is determined that the charging conditions are met, charging starts and the charging time is recorded from zero.

[0113] In some optional embodiments, when it is determined that the charging conditions are met, if a slow charging gun is inserted, the slow charging mode is entered; if a fast charging gun is inserted, the normal fast charging mode is entered; if both a slow charging gun and a fast charging gun are inserted at the same time, the super fast charging mode is entered.

[0114] If it is determined that the charging conditions are not met, charging will not start, and the current state of the vehicle will be continuously monitored. When the current state of the vehicle changes, the signal array set will be updated, and it will be determined again whether the charging conditions are met.

[0115] In some optional embodiments, when it is determined that the charging conditions are met, the current state of the vehicle may be continuously monitored, the signal array set is updated when the current state of the vehicle changes, and it is determined again whether the charging conditions are met.

[0116] In step S203, when it is monitored that the charging process is abnormally terminated, the abnormal charging reason, charging duration and current time are obtained.

[0117] In some optional embodiments, when it is monitored that the charging process is abnormally terminated, a signal array set is acquired, and the signal array set is used as the cause of the abnormal charging.

[0118] It can be understood that the bit values ​​of the n signal bits in the signal array set are determined according to the current state of the vehicle. Therefore, when it is detected that the charging process is abnormally terminated, the signal array set can intuitively reflect the specific reason for the abnormal termination of the charging process. Therefore, the signal array set can be directly used as the reason for abnormal charging for subsequent storage.

[0119] When no abnormal termination of the charging process is detected, a complete charging process is completed normally.

[0120] In step S204, the corresponding abnormal charging reason, charging duration and current time are stored as a set of abnormal data.

[0121] After the corresponding abnormal charging reasons, charging duration and current time are stored as a set of abnormal data, statistics can be performed based on at least one set of abnormal data, and statistical management can be performed on the factors causing abnormal charging termination, and the corresponding faults can be repaired and eliminated, or the vehicle's electronic control system can be improved to avoid subsequent abnormal charging process terminations. Even if the charging control conditions of different projects or platforms are different, a unified management method can be used for charging management, which is conducive to efficient and flexible unified management and statistics of charging.

[0122] In step S205, when the number of groups of stored abnormal data exceeds a preset number of groups, the first group of stored abnormal data is deleted.

[0123] By adopting the new energy vehicle charging management method provided by the present application, when it is detected that the charging gun is inserted and the charging conditions are met, it means that charging can be carried out. At this time, charging starts and the charging process is monitored in real time to see whether there is an abnormal termination. When it is detected that the charging process is abnormally terminated, it is necessary to collect the reasons for the abnormal charging termination for subsequent corresponding summary and corresponding improvement. At this time, the reasons for abnormal charging, charging time and current time are obtained, and the reasons for abnormal charging, charging time and current time are stored accordingly, so as to realize efficient and flexible unified management and statistics of charging.

[0124] The present application also provides a new energy vehicle charging management device, which can be set in a vehicle controller, such as Figure 4 As shown, the device includes a condition module 401, a charging module 402, a suspension module 403 and a recording module 404, wherein:
