[0033] In view of the problem of vehicle battery pack unlocking failure in the prior art, the present application provides a battery pack unlocking method, system, device, medium and program product. Through the technical solution provided by the present application, an auxiliary unlocking method is added during the unlocking process of the battery pack, and the auxiliary unlocking method can be used to unlock the battery pack in the event of unlocking failure, thereby improving the unlocking rate of the locking mechanism and the success rate of battery replacement. The technical solution provided by the present application will be explained and illustrated in combination with the embodiments below.

[0034] In some embodiments of the present disclosure, Figure 1 A flowchart of a battery pack unlocking method is provided. Figure 1 As shown, the battery pack unlocking method may specifically include: Step 110: Obtain vehicle information of the vehicle to be replaced, and parse the corresponding initial unlocking position and first target number of laps according to the vehicle information. The vehicle to be replaced first submits a replacement application when entering the replacement station. The replacement station system responds to the replacement application and obtains the vehicle information from the replacement system or cloud database. The initial unlocking position and first target number of laps of the same type of vehicle are parsed through the vehicle information to provide accurate unlocking data for the vehicle of that type.

[0035] Step 120: Move the torque gun to the initial unlocking position and engage the locking mechanism. The locking mechanism is used to fix the battery pack to the bottom of the vehicle; specifically, the vehicle to be replaced is moved to a designated position in the battery replacement station, and the torque gun is moved to the initial unlocking position by a moving device, and the torque gun is engaged with the locking mechanism to cooperate with the subsequent unlocking operation.

[0036] Step 130: Control the torque gun to rotate in the unlocking direction at the first torque for a first preset time, and obtain the number of revolutions of the torque gun after the first preset time, which is recorded as the first number of revolutions. It is understandable that the first torque can be preset according to the vehicle type or can be manually input by the operator.

[0037] Step 140: If it is determined that the first rotation number is not less than the first target number of rotations, the pre-unlocking of the locking mechanism is successful, and the torque gun is controlled to perform secondary unlocking to complete the unlocking of the locking mechanism. It can be understood that if the pre-unlocking of the locking mechanism is successful, the lock body of the locking mechanism becomes loose, and the torque gun can be adjusted to perform secondary unlocking to complete the full unlocking of the locking mechanism, thereby avoiding damage to the lock body caused by continuous rotation of the large first torque.

[0038] Step 150: If it is determined that the first rotation number is less than the first target number of rotations, the pre-unlocking of the locking mechanism fails, and the auxiliary unlocking method is used to unlock the locking mechanism. It is understandable that the auxiliary unlocking method is used to unlock the locking mechanism after the pre-unlocking of the locking mechanism fails, which can improve the unlocking success rate.

[0039] Through the above steps 110 to 150, in the technical solution of the present invention, a torque gun is first used to pre-unlock the locking mechanism using a first torque. When the pre-unlocking is successful, the lock body in the locking mechanism becomes loose, and then the secondary unlocking is used to completely unlock the locking mechanism and replace the battery pack; when the pre-unlocking fails, an auxiliary unlocking method is used to unlock the locking mechanism to improve the unlocking success rate of the locking mechanism, reduce the number of fault repairs, and improve the battery replacement efficiency of the battery replacement station.

[0040] In the above embodiment, in the specific implementation of the above step 150, Figure 2 A schematic diagram of a flow chart of an auxiliary unlocking method is shown. Figure 2 As shown, the following steps may be specifically included: Step 151: Increase the first torque to the second torque, control the torque gun to rotate in the unlocking direction at the second torque for a first preset time, and obtain the number of revolutions of the torque gun within the first preset time, which is recorded as the second number of revolutions. In this embodiment, the second torque is not less than twice the first torque, so that a larger torque is used to impact the locking mechanism for unlocking.

[0041] Step 152: If it is determined that the second rotation number is not less than the first target number, the pre-unlocking of the locking mechanism is successful.

[0042] Step 153: Control the torque gun to perform secondary unlocking to complete unlocking of the locking mechanism.

[0043] Step 154: If it is determined that the second rotation number is less than the first target rotation number, the pre-unlocking of the locking mechanism fails.

[0044] Step 155: Determine whether there is a recoil flag.

[0045] Step 156: If the recoil mark does not exist, control the torque gun to rotate in the locking direction with the third torque for a second preset time; it is understandable that if the torque gun still fails to pre-unlock under the action of the second torque, a reverse impact force is applied to the lock body for secondary auxiliary unlocking, so that the lock body in the locking mechanism vibrates, which helps to loosen the parts that have become stiff due to long-term non-use. If a reverse impact has been performed (that is, the recoil mark exists) and the pre-unlocking is still not successful, it indicates that the reverse impact is invalid and there is no need to perform the reverse impact again. Therefore, if the torque gun still fails to pre-unlock under the action of the second torque and the recoil mark does not exist, controlling the torque gun to rotate in the locking direction for the second preset time under the action of the third torque helps to improve the unlocking success rate. Step 157: Record the recoil mark, and return to the above step 130 to unlock. It can be understood that after the torque gun rotates in the unlocking direction for a second preset time under the action of the third torque, the recoil mark is recorded, which means that the torque gun in the auxiliary unlocking method performs a reverse impact once.

[0046] Step 158: Determine if the recoil mark exists, and feed back warning information to the interactive end. Among them, the warning information includes voice information and / or light information and / or text information and / or image information; the voice information is used to issue an unlock error warning sound; the light information is used to flash the unlock error warning light; the text information is used to display an unlock error text pop-up window on the operation interface; the image information is used to display symbols or patterns on the operation interface. If the vehicle still fails to unlock after the torque and reverse impact, it is considered that the unlocking has failed and a warning message needs to be issued. It is worth mentioning that due to the differences in the battery pack locking mechanism and the flatness of the vehicle body, the unlocking failure cannot be completely solved. Therefore, after the unlocking finally fails, the operator is reminded to pay attention through warning lights, system text pop-ups, warning sounds, warning symbols or warning patterns, and manual repair unlocking is performed. It can be understood from steps 151-152-153 that since the locking torque generated by the locking mechanism during the last locking is greater than the first torque, the first torque is increased to the second torque. By increasing the torque to impact the lock body of the locking mechanism, the locking mechanism can be pre-unlocked, thereby improving the unlocking success rate of the locking mechanism.

[0047] In the above embodiment, the recoil flag indicates whether the torque gun is controlled to rotate in the locking direction with a third torque for a second preset time after the pre-unlocking of the locking mechanism of the vehicle to be unlocked fails, so as to determine whether the auxiliary unlocking is reversely impacted to perform secondary auxiliary unlocking after the pre-unlocking of the locking mechanism of the vehicle to be unlocked fails after increasing the torque.

[0048] Through steps 151-154-155-156-157, it can be understood that when the lock body in the locking mechanism is stuck during unlocking, the rapid reverse force can generate vibration, which helps to loosen the parts that have become stiff due to long-term non-use. When the jamming between the internal parts of the lock body is slightly loosened due to this impact, the jamming caused by rust or dust accumulation can be easily removed, and at this time, it can return to step 130 for pre-unlocking.

[0049] In the above embodiment, first, the locking mechanism is impact unlocked by increasing the torque to increase the success rate of unlocking the locking mechanism; when the increase in torque still fails to unlock, a reverse impact in the opposite direction of the unlocking is provided and then unlocked by step 130 to further improve the unlocking efficiency of the locking mechanism. The auxiliary unlocking method in this embodiment has two levels of auxiliary unlocking, which can significantly improve the success rate of unlocking the locking mechanism in practical applications. The analysis data of battery pack unlocking using the auxiliary unlocking method and the method without the auxiliary unlocking method are as follows:

[0050] From the above table, it can be known that after adopting the unlocking method of the technical solution disclosed in the present invention, the unlocking failure rate is reduced by 90.95%, the unlocking rate of the locking mechanism is improved, the number of fault repairs is reduced, and the battery replacement efficiency of the battery replacement station is improved.

[0051] In the above embodiment, in the specific implementation of the above step 140, Figure 3 A schematic diagram of a secondary unlocking method is shown. Figure 3 As shown, the specific steps include: Step 141: Reduce the first torque to the fourth torque, control the torque gun to rotate in the unlocking direction with the fourth torque, and obtain the third number of rotations of the torque gun in real time. It should be noted that after the locking mechanism is pre-unlocked successfully, the lock body in the locking mechanism does not need to use a large torque to unlock. Therefore, when controlling the torque gun to perform secondary unlocking, the torque is reduced from the first torque to the fourth torque.

[0052] Step 142: If the third number of rotations is greater than the second target number of rotations, the second level unlocking is completed and the locking mechanism is unlocked successfully; wherein, the second target number of rotations is obtained from the battery exchange system or the cloud database according to the vehicle information for comparison with the third number of rotations. When the third number of rotations is greater than the second target number of rotations, the lock body in the locking mechanism is unlocked and the battery pack can be removed from the vehicle.

[0053] Step 143: If the third rotation number is not greater than the second target number; it is understandable that when the third rotation number is less than or equal to the second target number, the secondary unlocking is not completed, and the torque gun still needs to continue rotating in the unlocking direction.

[0054] Step 144: Control the torque gun to continuously rotate in the unlocking direction until the third number of rotations is greater than the second target number of rotations, then the secondary unlocking is completed and the locking mechanism is unlocked successfully.

[0055] Through the above steps 141 to 144, in the technical solution disclosed in the present invention, the first torque used by the torque gun during pre-unlocking is used to rotate the lock body in the locking mechanism, and after the pre-unlocking is successful, the fourth torque less than the first torque is used to continuously unlock the locking mechanism. In this embodiment, the fourth torque less than the first torque is used to perform secondary unlocking of the locking mechanism, which, on the one hand, ensures the stability of the unlocking process of the locking mechanism, and on the other hand, avoids the damage of the locking mechanism caused by the long-term impact of the large torque on the locking mechanism, thereby increasing the service life of the locking mechanism.

[0056] In some embodiments of the present disclosure, Figure 4 A schematic diagram of the structure of a battery pack unlocking device is provided. Figure 4 As shown, the battery pack unlocking device is used to implement the battery pack unlocking method provided in the above embodiment, which may specifically include: Collection unit 501: obtains vehicle information of the vehicle to be replaced, and parses the corresponding initial unlocking position and first target number of laps based on the vehicle information.

[0057] Moving unit 502: moves the torque gun to the initial unlocking position and engages the locking mechanism.

[0058] Execution unit 503: Control the torque gun to rotate in the unlocking direction at a first torque for a first preset time, and obtain a first number of rotations of the torque gun after the first preset time.

[0059] The first judgment processing unit 504 judges that if the first rotation number is not less than the first target number of rotations, the pre-unlocking of the locking mechanism is successful, and controls the torque gun to perform secondary unlocking to complete the unlocking of the locking mechanism.

[0060] The second judgment processing unit 505: if it is judged that the first number of rotations is less than the first target number of rotations, the pre-unlocking of the locking mechanism fails, and the auxiliary unlocking method is used to unlock the locking mechanism.
