Description

Technical Field

[0001] This application relates to the field of automotive electronic management, and in particular to a charging management method and device for new energy vehicles. Background Technology

[0002] New energy vehicles include pure electric vehicles and plug-in hybrid electric vehicles. These types of new energy vehicles can be charged by an external power source, enabling them to travel a certain distance in electric mode.

[0003] Many factors can affect charging from the start to the end of the charging process, and these factors may cause the charging process to be interrupted abnormally. The factors that cause such abnormal interruptions need to be statistically managed in order to prevent the abnormal interruption of the charging process from happening again in the future.

[0004] Currently, the management of charging for new energy vehicles is relatively fragmented. Different projects or platforms have different charging control conditions, which leads to differences in management methods and makes it difficult to efficiently and flexibly manage and statistically analyze charging. Summary of the Invention

[0005] In view of this, this application provides a method for managing the charging of new energy vehicles, which is conducive to efficient and flexible unified management and statistics of charging. The method includes:

[0006] On the one hand, this application provides a method for managing the charging of new energy vehicles, the method including:

[0007] When the charging gun is detected to be inserted, it is determined whether the charging conditions are met.

[0008] Once the charging conditions are determined to be met, charging begins and the charging process is monitored for any abnormal termination.

[0009] When an abnormal charging process is detected, obtain the reason for the abnormal charging, the charging duration, and the current time.

[0010] Store the cause of the abnormal charging, the charging duration, and the current time accordingly.

[0011] Optionally, when the charging gun is detected to be inserted, determining whether the charging conditions are met includes:

[0012] When the charging gun is detected to be inserted, the vehicle's power-on mode, current vehicle status, and model identification are obtained.

[0013] Based on the vehicle's power-on mode, obtain the corresponding signal array set and calibration array set. The signal array set consists of m bits, including n signal bits and blank bits other than 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 other than the n calibration bits. The bit values ​​of the n calibration bits in the calibration array set are determined according to the vehicle model identifier, where n≤m.

[0014] Perform a logical AND operation on the signal array set and the calibration array set to obtain the total number of bit values.

[0015] Determine whether the total number of bit values ​​is greater than or equal to a preset value.

[0016] When the total number of bit values ​​is determined to be greater than or equal to the preset value, the charging condition is determined to be met.

[0017] Alternatively, different vehicle power-on modes correspond to different signal array sets, where the total number of m bits is the same in different signal array sets, but the total number of n signal bits is different.

[0018] Different vehicle power-on modes correspond to different calibration array sets. In different calibration array sets, the total number of m bits is the same, but the total number of n calibration bits is different.

[0019] Alternatively, the method may also include:

[0020] When the charging conditions are determined to be met, charging begins and the charging time is recorded from zero.

[0021] When an abnormal charging interruption is detected, the following information is obtained: the cause of the abnormal charging, the charging duration, and the current time.

[0022] When an abnormal termination of the charging process is detected, the signal array set is obtained and used as the cause of the abnormal charging.

[0023] Optionally, the cause of the abnormal charging, the charging duration, and the current time can be stored accordingly, including:

[0024] The corresponding abnormal charging reason, charging duration, and current time are stored as a set of abnormal data.

[0025] The method also includes:

[0026] When the number of stored abnormal data sets exceeds the preset number, the first stored abnormal data set will be deleted.

[0027] On the other hand, this application also provides a new energy vehicle charging management device, the device comprising:

[0028] The condition module is configured to determine whether the charging conditions are met when the charging gun is detected to be inserted.

[0029] The charging module is configured to start charging when it is determined that the charging conditions are met and to monitor whether the charging process is abnormally terminated.

[0030] The abort module is configured to obtain the reason for the abnormal charging, the charging duration, and the current time when an abnormal charging process is detected.

[0031] The recording module is configured to store the cause of abnormal charging, charging duration, and current time.

[0032] Alternatively, the condition module is configured as follows:

[0033] When the charging gun is detected to be inserted, the vehicle's power-on mode, current vehicle status, and model identification are obtained.

[0034] Based on the vehicle's power-on mode, obtain the corresponding signal array set and calibration array set. The signal array set consists of m bits, including n signal bits and blank bits other than 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 other than the n calibration bits. The bit values ​​of the n calibration bits in the calibration array set are determined according to the vehicle model identifier, where n≤m.

[0035] Perform a logical AND operation on the signal array set and the calibration array set to obtain the total number of bit values.

[0036] Determine whether the total number of bit values ​​is greater than or equal to a preset value.

[0037] When the total number of bit values ​​is determined to be greater than or equal to the preset value, the charging condition is determined to be met.

[0038] Alternatively, different vehicle power-on modes correspond to different signal array sets, where the total number of m bits is the same in different signal array sets, but the total number of n signal bits is different.

[0039] Different vehicle power-on modes correspond to different calibration array sets. In different calibration array sets, the total number of m bits is the same, but the total number of n calibration bits is different.

[0040] Optionally, the charging module is also configured as follows:

[0041] When the charging conditions are determined to be met, charging begins and the charging time is recorded from zero.

[0042] The abort module is also configured as follows:

[0043] When an abnormal termination of the charging process is detected, the signal array set is obtained and used as the cause of the abnormal charging.

[0044] Optionally, the recording module is configured as follows:

[0045] The corresponding abnormal charging reason, charging duration, and current time are stored as a set of abnormal data.

[0046] When the number of stored abnormal data sets exceeds the preset number, the first stored abnormal data set will be deleted.

[0047] By adopting the new energy vehicle charging management method provided in this application, when the charging gun is detected to be inserted and the charging conditions are met, it indicates that charging can begin. At this time, charging starts and the charging process is monitored in real time to see if any abnormal interruption occurs. When an abnormal interruption is detected, the cause of the abnormal interruption needs to be collected for subsequent summary and improvement. At this time, the cause of abnormal charging, charging duration, and current time are obtained and stored accordingly, thereby achieving efficient and flexible unified management and statistics of charging.

[0053] 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.

[0054] The technical problem this application aims to solve is that plug-in charging is essential for both pure electric vehicles and plug-in hybrid electric vehicles, as it increases vehicle range. However, due to numerous safety hazards associated with electrical energy transfer, various complex situations must be considered when entering or exiting the charging function to avoid unexpected or untimely exits. Therefore, effective coordination of the vehicle's charging function is necessary, and the ability to visually monitor charging results is beneficial for after-sales maintenance. In the event of an unexpected situation that causes charging to exit, the relevant signal status at the time of exit should be automatically stored, facilitating future scheduled repairs.

[0055] Compared with the prior art, the embodiments of this application are more comprehensive, listing the relevant conditions and distinguishing different conditions according to different vehicle states. At the same time, each condition is configured with an independent calibration value, which can be combined and matched in specific ways according to platform and project configuration, making it more flexible.

[0056] Specifically, this 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 conditions are met.

[0058] In step S102, when it is determined that the charging conditions are met, charging begins and the charging process is monitored to see if it is abnormally terminated.

[0059] In step S103, when an abnormal termination of the charging process is detected, the cause of the abnormal charging, the charging duration, and the current time are obtained.

[0060] In step S104, the cause of the abnormal charging, the charging duration, and the current time are stored accordingly.

[0061] In some optional embodiments, determining whether the charging conditions are met when the charging gun is detected to be inserted includes:

[0062] When the charging gun is detected to be inserted, the vehicle's power-on mode, current vehicle status, and model identification are obtained.

[0063] Based on the vehicle's power-on mode, obtain the corresponding signal array set and calibration array set. The signal array set consists of m bits, including n signal bits and blank bits other than 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 other than the n calibration bits. The bit values ​​of the n calibration bits in the calibration array set are determined according to the vehicle model identifier, 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 the total number of bit values ​​is determined to be greater than or equal to the preset value, the charging condition is determined to be 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, while the total number of n signal bits is different.

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

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

[0070] When the charging conditions are determined to be met, charging begins and the charging time is recorded from zero.

[0071] When an abnormal charging interruption is detected, the following information is obtained: the cause of the abnormal charging, the charging duration, and the current time.

[0072] When an abnormal termination of the charging process is detected, the signal array set is obtained and used as the cause of the abnormal charging.

[0073] In some optional embodiments, storing the cause of the abnormal charging, the charging duration, and the current time includes:

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

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

[0076] When the number of stored abnormal data sets exceeds the preset number, the first stored abnormal data set will be deleted.

[0077] By adopting the new energy vehicle charging management method provided in this application, when the charging gun is detected to be inserted and the charging conditions are met, it indicates that charging can begin. At this time, charging starts and the charging process is monitored in real time to see if any abnormal interruption occurs. When an abnormal interruption is detected, the cause of the abnormal interruption needs to be collected for subsequent summary and improvement. At this time, the cause of abnormal charging, charging duration, and current time are obtained and stored accordingly, thereby achieving efficient and flexible unified management and statistics of charging.

[0078] This application also provides another method for managing the charging of new energy vehicles, which is implemented by the 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 conditions are met.

[0080] In some optional embodiments, this application uses an array set to determine whether the charging conditions are met, thereby achieving customizability and flexibility in the charging condition determination process. The array set can be created programmatically. Specifically, determining whether the charging conditions are met when the charging gun is detected includes:

[0081] When the charging gun is detected to be inserted, the vehicle's power-on mode, current vehicle status, and model identification are obtained.

[0082] It is understood that vehicle power-on modes include OFF mode, ACC mode, ON mode, and READY mode. Current vehicle status includes charging gun status, battery charging request status, OBC fault status, DC-DC fault status, intelligent charging progress status, remote start progress status, external discharge progress status, collision-related fault status, circuit fault status, battery level status, vehicle speed status, communication fault status, and TBOX fault status. Vehicle model identification can use the VIN (Vehicle Identification Number) or a separate vehicle model identifier.

[0083] After obtaining the vehicle's power-on mode, it is necessary to obtain the corresponding signal array set and calibration array set according to the vehicle's power-on mode. The signal array set consists of m bits, including n signal bits and blank bits other than 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 other than the n calibration bits. The bit values ​​of the n calibration bits in the calibration array set are determined according to the vehicle model identifier, 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, while the total number of n signal bits is different.

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

[0086] In some optional embodiments, a set of signal arrays and a set of calibration arrays corresponding to the vehicle's power-on mode can be pre-calibrated and stored, such as... Figure 3 As shown, m is 16. In other words, both the signal array set and the calibration array set are array sets consisting of 16 bits, i.e., two-dimensional array type variables. The signal array set corresponding to OFF mode is A1, the signal array set corresponding to ACC mode is A2, the signal array set corresponding to ON mode is A3, and the signal array set corresponding to 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 there are more than 16 conditions associated with charging, the size of the array set can be increased accordingly, such as setting an array set consisting of 32 or 64 bits.

[0088] If the vehicle has other power-on modes besides OFF, ACC, ON, and READY, you can set up more column array sets, with the number of columns in the array set matching the number of vehicle power-on modes.

[0089] For example, such as Figure 3As shown, the 16 bits of the signal array set A1 include 12 signal bits, which are Num0, Num1, Num2, Num3, Num4, Num5, Num6, Num7, Num8, Num9, Num11 and Num12. Apart from these 12 signal bits, all other bits in the 16 bits are blank.

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

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

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

[0093] The bit values ​​of the n signal bits in the signal array set are determined based on 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 determined based on the charging gun state, battery charging request state, OBC fault state, DCDC fault state, intelligent charging process state, remote start process state, external discharge process state, collision-related fault state, circuit fault state, battery power state, vehicle speed state, communication fault state, and TBOX fault state, respectively. Specifically, when the charging gun status indicates that the charging gun is inserted, the bit value of Num0 is 1; when the battery charging request status indicates that a request has been made, the bit value of Num1 is 1; when the OBC fault status indicates no fault, the bit value of Num2 is 1; when the DCDC fault status indicates no fault, the bit value of Num3 is 1; when the intelligent charging process status indicates that it is not in progress, the bit value of Num4 is 1; when the remote start process status indicates that it is not in progress, the bit value of Num5 is 1; when the external discharge process status indicates that it is not in progress, the bit value of Num6 is 1; when the collision-related fault status indicates no fault, the bit value of Num7 is 1; when the circuit fault status indicates no fault, the bit value of Num8 is 1; when the battery power status indicates that the battery SOC is within the threshold range, the bit value of Num9 is 1; when the vehicle speed status indicates that the vehicle speed is below the threshold, the bit value of Num10 is 1; when the communication fault status indicates no CAN communication fault, the bit value of Num10 is 1. The bit value of Num11 is 1. When the TBOX fault status indicates no fault, the bit value of Num12 is 1. Otherwise, the bit value of Num0, Num1, Num2, Num3, Num4, Num5, Num6, Num7, Num8, Num9, Num10, Num11 and Num12 is 0.

[0094] In some optional embodiments, upon detecting the insertion of a charging gun, the signal array set can be initialized by setting all bit values ​​in the signal array set to 0. After a preset time, the bit values ​​of n signal bits in the signal array set are then determined based on the current state of the vehicle. The preset time can be 2 seconds.

[0095] In summary, the bit values ​​of n signal bits in the signal array can be determined based on the current state of the vehicle, thereby further determining whether the vehicle meets the charging conditions.

[0096] For all vehicle models, four fixed signal array sets can be set corresponding to the four vehicle charging modes, which facilitates unified management and avoids the need to frequently change and customize the signal array sets due to different vehicle models and charging conditions, thus increasing the difficulty of charging management.

[0097] Similar to signal arrays, such as Figure 3 As shown, the calibration array set corresponding to OFF mode is B1, the calibration array set corresponding to ACC mode is B2, the calibration array set corresponding to ON mode is B3, and the calibration array set corresponding to READY mode is B4. For different vehicle power-on modes (OFF mode, ACC mode, ON mode, and READY mode), the number of n calibration positions included in the m bits of the corresponding calibration array set is different. In other words, the number of calibration positions 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, such as Figure 3 As shown, the 16 bits of the calibration array set B1 include 12 calibration positions. The positions of the 12 calibration positions correspond to the positions of the 12 signal bits in the signal array set A1. Apart from these 12 calibration positions, all other bits in the 16 bits are blank.

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

[0100] The 16 bits of the calibration array set B3 include 9 calibration positions. The positions of the 9 calibration positions correspond to the positions of the 9 signal bits in the signal array set A3. Apart from these 9 calibration positions, all other 16 bits are blank.

[0101] The 16 bits of the calibration array set B4 include 10 calibration positions. The positions of the 10 calibration positions correspond to the positions of the 10 signal bits in the signal array set A4. Apart from these 10 calibration positions, all other bits in the 16 bits are blank.

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

[0103] It is understandable that the bit values ​​of the n calibration positions in the calibration array set are determined according to the vehicle model identifier. 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 particular vehicle model does not require consideration of one or more specific charging conditions—in other words, the bit values ​​of all n signal bits in the signal array set do not need to be considered, and some signal bit values ​​do not need to be considered—then the bit values ​​of the corresponding calibration positions for these signal bits can be directly set to 0 in the calibration array set, while the bit values ​​of the corresponding calibration positions for other signal bits are set to 1. Therefore, when performing a logical AND operation on the signal array set and the calibration array set subsequently, regardless of whether the corresponding signal bit value is 0 or 1, the bit value obtained after performing a logical AND operation between the calibration position with a bit value of 0 and the corresponding signal bit value will always be 0. This successfully achieves the goal of setting the bit values ​​of these signal bits to zero, ignoring their bit values. This satisfies situations where the signal array set needs to be changed and customized due to different vehicle models and charging conditions. It reduces the difficulty of charging management and also enables customizable charging management, improving its flexibility.

[0104] like Figure 3 As shown, if a certain vehicle model does not need to consider the external discharge process, the bit value of the calibration position corresponding to Num6 in the calibration array set and the signal array set is directly set to 0. The value obtained by performing a logical AND operation between the calibration position corresponding to the signal position Num6 in the calibration array set and the signal position Num6 in the signal array set will always be 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 a bit value of 1 in the calibration array set. This characteristic can be used to verify the accuracy of the calibration array set.

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

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

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

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

[0110] In step S202, when it is determined that the charging conditions are met, charging begins and the charging process is monitored to see if it is abnormally terminated.

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

[0112] When the charging conditions are determined to be met, charging begins 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 system enters slow charging mode; if a fast charging gun is inserted, the system enters normal fast charging mode; and if both a slow charging gun and a fast charging gun are inserted at the same time, the system enters super fast charging mode.

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

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

[0116] In step S203, when an abnormal termination of the charging process is detected, the cause of the abnormal charging, the charging duration, and the current time are obtained.

[0117] In some optional embodiments, when an abnormal termination of the charging process is detected, a set of signal arrays is acquired and used as the cause of the abnormal charging.

[0118] It is understandable that the bit values ​​of the n signal bits in the signal array set are determined based on the current state of the vehicle. Therefore, when an abnormal termination of the charging process is detected, the signal array set can intuitively show the specific reason for the abnormal termination of the charging process. Thus, the signal array set can be directly used as the reason for the abnormal charging for subsequent storage.

[0119] If no abnormal interruption 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 storing the corresponding abnormal charging reasons, charging duration, and current time as a set of abnormal data, statistics can be performed based on at least one set of abnormal data to statistically manage the factors that cause abnormal charging interruptions, and to repair and eliminate the corresponding faults or improve the vehicle's electronic control system, thereby preventing abnormal charging interruptions from occurring again in the future. 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 stored abnormal data sets exceeds the preset number of sets, the first stored abnormal data set is deleted.

[0123] By adopting the new energy vehicle charging management method provided in this application, when the charging gun is detected to be inserted and the charging conditions are met, it indicates that charging can begin. At this time, charging starts and the charging process is monitored in real time to see if any abnormal interruption occurs. When an abnormal interruption is detected, the cause of the abnormal interruption needs to be collected for subsequent summary and improvement.
