[0060] In view of the problem of vehicle battery pack unlocking failure in the prior art, the application provides a battery pack unlocking method, system, device, medium and program product. Through the technical solution provided by the application, an auxiliary unlocking method is added in the unlocking process of the battery pack, which can use the auxiliary unlocking method to unlock in the case of unlocking failure, improve the unlocking rate of the locking mechanism, and improve the battery replacement success rate. The technical solution provided by the application will be explained and described in combination with embodiments.

[0061] In some embodiments of the present disclosure, Figure 1 A flowchart of a battery pack unlocking method is provided. As Figure 1 shown, the battery pack unlocking method can specifically include:

[0062] Step 110: obtaining vehicle information of a vehicle to be replaced, and analyzing an initial unlocking position and a first target number of turns corresponding to the vehicle information. Wherein, the vehicle to be replaced enters the battery replacement station and first submits a battery replacement application, the battery replacement station system responds to the battery replacement application and obtains the vehicle information from the battery replacement system or the cloud database, analyzes the initial unlocking position and the first target number of turns of the same type of vehicle through the vehicle information, so as to provide accurate unlocking data for the vehicle of this type.

[0063] Step 120: moving the torque gun to the initial unlocking position and clamping the locking mechanism. Wherein, the locking mechanism is used to fix the battery pack to the bottom of the vehicle; specifically, the vehicle to be replaced moves to a designated position in the battery replacement station, the torque gun is moved to the initial unlocking position by the moving device, and the torque gun is clamped to the locking mechanism to cooperate with the subsequent unlocking operation.

[0064] Step 130: control the torque gun to rotate in the unlocking direction with a first torque for a first preset time, and obtain the number of turns of the torque gun after the first preset time, which is recorded as the first number of turns. It can be understood that the above-mentioned first torque can be pre-set according to the type of vehicle, or manually input by the operator.

[0065] Step 140: if the first number of turns is not less than the first target number of turns, 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 is loose, and the torque gun can be adjusted to perform secondary unlocking to complete the complete unlocking of the locking mechanism, so as to avoid damage to the lock body caused by the continuous rotation of the large first torque.

[0066] Step 150: if the first number of turns is less than the first target number of turns, the pre-unlocking of the locking mechanism fails, and an auxiliary unlocking method is used to unlock the locking mechanism. It can be understood 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.

[0067] Through steps 110 to 150, in the technical solution of the present disclosure, the locking mechanism is first pre-unlocked using a torque gun with a first torque, and when the pre-unlocking is successful, the lock body in the locking mechanism is loosened, and then the complete unlocking of the locking mechanism is completed using secondary unlocking to replace the battery pack; when the pre-unlocking fails, the locking mechanism is unlocked using an auxiliary unlocking method to improve the unlocking success rate of the locking mechanism and reduce the number of fault repairs, thereby improving the battery replacement efficiency of the battery replacement station.

[0068] In the foregoing embodiment, in the specific implementation in step 150, Figure 2 A flowchart of an auxiliary unlocking method is shown. As Figure 2 shown, the specific steps can include the following steps:

[0069] 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 rotations of the torque gun within the first preset time, denoted as the second rotation number. 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.

[0070] Step 152: If the second rotation number is not less than the first target number, the pre-unlocking of the locking mechanism is successful.

[0071] Step 153: Control the torque gun to perform secondary unlocking to complete the unlocking of the locking mechanism.

[0072] Step 154: If the second rotation number is less than the first target number, the pre-unlocking of the locking mechanism fails.

[0073] Step 155: Determine whether the backflush flag exists.

[0074] Step 156: If the backflush flag does not exist, control the torque gun to rotate in the locking direction at the third torque for a second preset time; it can be understood that if the torque gun still fails to successfully 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 is vibrated, which helps to loosen the components that have become rigid due to long-term non-use. If the reverse impact has already been performed (i.e., the backflush flag exists) and the pre-unlocking is still unsuccessful, it indicates that the reverse impact is ineffective, and the reverse impact does not need to be performed again. Therefore, if the torque gun still fails to successfully pre-unlock under the action of the second torque and the backflush flag does not exist, the torque gun is controlled to rotate in the locking direction at the third torque for a second preset time, which helps to improve the unlocking success rate.

[0075] Step 157: record the recoil flag, and return to the above-mentioned step 130 for unlocking. It can be understood that the torque gun rotates in the unlocking direction for a second preset time under the action of the third torque, and the recoil flag is recorded, which means that the torque gun in the auxiliary unlocking method impacts in the reverse direction once.

[0076] Step 158: judge the existence of the recoil flag, and feed back the warning information to the interactive terminal. The warning information includes voice information or / and light information or / and text information or / and image information; the voice information is used to issue the warning sound of unlocking error; the light information is used to flash the warning light of unlocking error; the text information is used to display the text pop-up window of unlocking error on the operation interface; the image information is used to display the symbol or pattern on the operation interface. It can be understood that if the torque and the reverse impact still fail to unlock after the reverse impact, it is considered that the unlocking fails, and the warning information needs to be issued. It is worth noting that due to the differences in the battery pack locking mechanism and the flatness of the vehicle body, it is impossible to completely solve the unlocking failure fault, so after the final unlocking failure, the warning light, system text pop-up window, warning sound and warning symbol or warning pattern are used to remind the operator to pay attention and manually repair the unlocking. Through steps 151-152-153, it can be understood 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, and the locking body of the locking mechanism is impacted by increasing the torque, the pre-unlocking of the locking mechanism can be completed, and the unlocking success rate of the locking mechanism is improved.

[0077] In the above embodiment, the recoil flag bit is whether the torque gun is controlled to rotate in the locking direction for a second preset time with a third torque after the pre-unlocking of the locking mechanism of the vehicle to be unlocked fails, so as to judge whether the secondary auxiliary unlocking is performed by impacting the locking mechanism in the reverse direction after the auxiliary unlocking still fails to pre-unlock successfully after the torque is increased.

[0078] Through steps 151-154-155-156-157, it can be understood that in the case that the locking body in the locking mechanism is locked, the rapid reverse force can generate vibration, which helps to loosen the parts that become rigid due to long-term non-use. After the locking between the internal parts of the locking body is slightly loosened due to this impact, the jamming caused by rust or dust accumulation can be easily removed, and then the pre-unlocking can be returned to step 130.

[0079] In the above embodiments, first, the locking mechanism is unlocked by increasing the torque to impact, increasing the success rate of unlocking the locking mechanism; when the increased torque still cannot unlock, the reverse impact in the opposite direction of the unlocking direction is provided before unlocking by step 130, further improving 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 unlocking success rate of the locking mechanism in actual application. The battery pack unlocking analysis data using the auxiliary unlocking method and not using the auxiliary method are as follows:

[0080]

[0081] From the above table, it can be known that after adopting the unlocking method of the technical solution of the present disclosure, the failure rate of unlocking is reduced by 90.95%, the unlocking rate of the locking mechanism is improved, the number of fault maintenance is reduced, and the battery swapping station swapping efficiency is improved.

[0082] In the above embodiments, in the specific implementation in the foregoing step 140, Figure 3 A flowchart of a two-level unlocking method is shown. As Figure 3 shown, it specifically includes the following steps:

[0083] Step 141: reduce the first torque to the fourth torque, control the torque gun to rotate along the unlocking direction at the fourth torque, and real-time acquire the third rotation number of the torque gun. It should be noted that after the locking mechanism is successfully pre-unlocked, the lock body in the locking mechanism does not need to be unlocked using a large torque, so when the torque gun is controlled to perform two-level unlocking, the torque is reduced from the first torque to the fourth torque.

[0084] Step 142: if the third rotation number is greater than the second target number, the two-level unlocking is completed, and the locking mechanism is unlocked successfully; wherein the second target number is acquired from the battery swapping system or the cloud database according to the vehicle information, and is compared with the third rotation number, when the third rotation number is greater than the second target number, the lock body in the locking mechanism is unlocked, and the battery pack can be disassembled from the vehicle.

[0085] Step 143: if the third rotation number is not greater than the second target number; it can be understood that when the third rotation number is less than or equal to the second target number, the two-level unlocking is not completed, and the torque gun still needs to continue to rotate along the unlocking direction.

[0086] Step 144: control the torque gun to continue to rotate along the unlocking direction until the third rotation number is greater than the second target number, then the two-level unlocking is completed, and the locking mechanism is unlocked successfully.

[0087] Through steps 141 to 144, in the technical solution of the present disclosure, the first torque used by the torque gun in the pre-unlocking is used to make the lock body in the locking mechanism rotate, and the fourth torque smaller than the first torque can be used to make the locking mechanism continuously unlock after the pre-unlocking is successful. In the embodiment, the fourth torque smaller than the first torque is used to perform two-stage unlocking on 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 damage to the locking mechanism caused by long-time impact of a large torque on the locking mechanism, thereby improving the service life of the locking mechanism.

[0088] In some embodiments of the present disclosure, Figure 4 A structural diagram of a battery pack unlocking device is provided. As Figure 4 shown, the battery pack unlocking device is used to implement the battery pack unlocking method provided in the foregoing embodiments, and specifically can include:

[0089] The acquisition unit 501 acquires vehicle information of a vehicle to be replaced, and parses an initial unlocking position and a first target number of turns corresponding to the vehicle information.

[0090] The moving unit 502 moves the torque gun to the initial unlocking position and clamps the locking mechanism.

[0091] The execution unit 503 controls the torque gun to rotate in the unlocking direction at a first torque for a first preset time, and acquires a first number of turns of the torque gun after the first preset time.

[0092] The first judgment processing unit 504 judges that the first number of turns is not less than the first target number of turns, and the pre-unlocking of the locking mechanism is successful, and controls the torque gun to perform two-stage unlocking to complete the unlocking of the locking mechanism.

[0093] The second judgment processing unit 505 judges that the first number of turns is less than the first target number of turns, and the pre-unlocking of the locking mechanism fails, and uses an auxiliary unlocking method to unlock the locking mechanism. It can be understood that the functions implemented by the acquisition unit to the processing module in the above functional modules correspond to the actions performed by steps 110 to 150 one by one, and will not be repeated here.
