Detailed Description
Preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention. And can be adjusted as needed by those skilled in the art to suit particular applications. For example, although the power swapping station is described in the present application, this is not limiting, and the technical solution of the present invention may also be applied to other facilities with a power swapping function, such as a power charging and swapping all-in-one station.
The problem that in the battery replacement process of a vehicle in the existing battery replacement station, locking is not completed or the vehicle is driven away from a parking platform under the condition that a bolt is not screwed down is solved, and further the risk of driving safety of the vehicle is caused.
As shown in fig. 1, the present invention provides a charging and unlocking control method for a charging station, which can solve a situation that a vehicle is driven away from a parking platform when a battery bolt of the vehicle is not screwed down in a plurality of different situations.
Specifically, in the process of locking the vehicle battery, an automatic locking process and a manual locking process are mainly divided. During the process of manually screwing the bolt of the vehicle battery, the battery replacement specialist judges whether the vehicle bolt is screwed down by observing a torque curve displayed in real time on an interactive interface. In this case, the probability that the vehicle will leave the parking platform in a state where the battery bolt is not locked is high, and thus, a safety problem is easily generated during the vehicle driving. In addition, in the automatic battery replacement and locking process, only a part of bolts on the battery of the vehicle are screwed due to the damage of the bolts or the faults of the battery, the battery replacement specialist needs to manually judge the locking state, and at the moment, the specialist/cloud background intervention may forget locking or does not complete locking, so that the vehicle finally leaves the parking platform. Moreover, in the process of manually replacing the battery in the whole process, the phenomenon that the vehicle is driven away from the battery replacement station without locking is easily caused. Based on the above description, and in order to solve the above problems, the power swapping station of the present invention includes a parking platform and a locking and unlocking mechanism, and the control method includes the following steps:
step S01, locking operation is carried out on a battery of a vehicle on the parking platform through a locking and unlocking mechanism;
step S02, after the locking operation is executed, unlocking operation is executed on the battery along the unlocking direction by torque smaller than the maximum locking torque;
s03, acquiring the rotating speed of the locking and unlocking mechanism along the unlocking direction;
and S04, determining whether the vehicle is allowed to drive away from the parking platform according to the rotating speed.
Step S01 is described in detail below with reference to fig. 2.
In the step of performing the locking operation on the battery of the vehicle on the parking platform through the locking and unlocking mechanism in step S01, the locking operation may be performed on a new battery to be installed and on an old battery to be unlocked, and specifically includes step S011 and step S012.
And S011, when the automatic locking and unlocking process does not report errors, installing a new battery on the vehicle and locking the new battery after unlocking the old battery of the vehicle on the parking platform through the locking and unlocking mechanism. When installing a new battery, firstly, the old battery on the vehicle needs to be unlocked and replaced, if no error is reported in the automatic locking and unlocking process, the program is normal, at the moment, the old battery on the vehicle is unlocked, after the old battery is replaced, the new battery needs to be installed on the vehicle, and at the moment, the locking operation is to lock the new battery.
Correspondingly, in the process of automatically unlocking an old battery needing to be replaced, a part of a bolt can be loosened, the bolt can be damaged, or the power station can be switched to be stopped, and at the moment, equipment needs to be overhauled, or the vehicle can not be replaced due to the fact that no accessory exists and other objective reasons. At this time, the old battery which is not replaced by the vehicle needs to be locked again, and the vehicle can be driven away from the parking platform after the old battery is locked. In the above process, step S012 needs to be executed, and when the automatic locking/unlocking process reports an error, the locking operation is performed again on the old battery of the vehicle before the locking/unlocking mechanism has started but the unlocking operation on the old battery has not been completed. At this time, the vehicle is in a condition that the old battery does not successfully complete unlocking, and in the condition, the bolts of the vehicle battery are ensured to be completely screwed, so the locking operation is carried out on the old battery again, the mode further improves the safety of battery replacement, and simultaneously ensures the safety of the vehicle.
At this time, since the automatic locking and unlocking process has a phenomenon of reporting an error, the automatic locking and unlocking process cannot complete the locking of the vehicle battery, and therefore, the step S012 may further include step S0121 of manually controlling the locking and unlocking mechanism to perform the locking operation again on the old battery. It should be noted that, similar to the foregoing description, "manually" in this application is not that the specially-assigned person manually screws the bolt, but the specially-assigned person manually operates the control panel (touch screen) of the battery swapping device to manually control the locking and unlocking mechanism to perform the locking operation.
In addition, when the automatic locking and unlocking process reports an error, before the locking and unlocking mechanism is manually controlled to re-lock the old battery, the control method of the invention further comprises the following steps: and the power swapping specialist or the cloud platform performs reset operation on the automatic locking and unlocking process so as to try to automatically eliminate the fault. If the fault can be automatically eliminated, the system continues to automatically lock and unlock; otherwise, the control panel (touch screen) of the battery replacement equipment is manually operated by the battery replacement specialist to manually control the locking and unlocking mechanism to lock.
In one embodiment, the power exchanging station further comprises a vehicle lifting mechanism arranged on the parking platform, and the vehicle lifting mechanism lifts the vehicle to a certain height (described in detail in connection with fig. 4 below) before the locking operation is performed. The arrangement mode can conveniently lock and unlock the vehicle, and the vehicle can be locked and unlocked on the parking platform after reaching a certain height.
Referring next to fig. 3, step S04 further includes step S041 and step S042. S041, if the rotating speed is not equal to zero, judging that the bolt is not screwed down, and forbidding the vehicle to drive away from the parking platform; and S042, if the rotating speed is equal to zero, judging that the bolt is screwed, and allowing the vehicle to drive away from the parking platform. In particular, if the rotation speed is not equal to zero, it is indicated that the bolt can be screwed in reverse, and it can therefore be determined that the bolt was not screwed when previously locked. Conversely, if the rotation speed is equal to zero, it indicates that the bolt cannot be screwed in the reverse direction, and it can be determined that the bolt has been screwed when the lock was previously locked.
Accordingly, regarding the torque less than the maximum locking torque in step S02, it can be flexibly set by those skilled in the art according to the characteristics of the bolt and the requirements of the tightening force for the specific vehicle model and battery. As an example, the torque may be about 80% of the maximum locking torque.
Further, the step of prohibiting the vehicle from leaving the parking platform in step S041 specifically includes step S0411: the vehicle lifting mechanism is prohibited from lowering the vehicle back onto the parking platform. Whether the vehicle returns to the parking platform is controlled through the vehicle lifting mechanism, and the arrangement mode can completely prevent the vehicle from driving away from the parking platform under the condition that bolts of a vehicle battery are not screwed down. That is to say, when the bolt of the vehicle battery is in a screwed state, the vehicle lifting mechanism can only lower the vehicle back to the parking platform, otherwise, the vehicle cannot be lowered back to the parking platform, and when the vehicle is not lowered back to the parking platform, the vehicle cannot drive away from the parking platform, so that the safety of the vehicle in the driving process is ensured.
When the vehicle lifting mechanism is prohibited from lowering the vehicle back onto the parking platform in step S0411, the control method further includes S04111: an alarm is issued to prohibit the vehicle from driving away. Through giving an alarm, the bolt condition of the vehicle battery can be more conveniently overhauled by a specialist/cloud background, and the next step is carried out at the same time.
In an alternative embodiment, the battery replacement station further comprises a working pit position arranged on the parking platform, the locking and unlocking mechanism is arranged in the working pit position, and the vehicle does not need to be lifted to a certain height in the battery replacement process, and the battery replacement of the vehicle is directly carried out in the working pit position of the locking and unlocking mechanism, so that the situation that the vehicle runs out of the battery replacement platform in the battery replacement process under the condition that the bolt is not screwed down on the vehicle battery cannot be avoided through the step of prohibiting the vehicle lifting mechanism from lowering the vehicle back to the parking platform in the battery replacement process. In the above case, if the command for prohibiting the vehicle from leaving the parking platform is received, it is indicated that there is a risk that the bolt on the vehicle is not tightened at this time, and step S0412 is directly executed to issue an alarm for prohibiting the vehicle from leaving. Through the alarm information that sends, remind the user that the vehicle battery exists unusually, also remind the special staff of trading the electricity to overhaul the situation of vehicle battery bolt simultaneously.
In order to prevent the unlocking mechanism from starting the operation flow of unlocking and locking under the condition that no vehicle is on the parking platform. As shown in fig. 4, before the unlocking operation is performed, it is necessary to confirm whether there is a vehicle on the parking platform, and therefore, the control method of the present invention further includes: s06, lifting the vehicle to a certain height through a vehicle lifting mechanism; s07, detecting the lifting torque of a vehicle lifting mechanism; step S08, comparing the lifting torque with a set threshold; and step S09, when the lifting torque is larger than a set threshold value, the parking platform is indicated to be provided with a vehicle, and therefore the battery locking and unlocking operation is allowed to be executed. On the contrary, when the lifting torque is smaller than or equal to the set threshold, it is indicated that no vehicle is on the power exchanging platform, in this case, the vehicle does not need to be exchanged, and therefore, the vehicle lifting mechanism can return to the original point. By way of example, ten locking and unlocking gun heads of the locking and unlocking mechanism of the battery replacement station are provided, and at present, the normal battery replacement vehicle needs to lock all the ten gun heads to the target torque/target number of turns before the vehicle can drive away.
In summary, in order to ensure that each bolt of the vehicle battery is in a tightened state when the vehicle is driven off the parking platform after the battery replacement is finished, the driving safety of the vehicle is further ensured. In addition, the situation that in the automatic locking and unlocking process, due to program logic errors and manual locking and unlocking process, due to expert/cloud background misjudgment, a bolt of a vehicle battery is driven away from a parking platform under the condition that the bolt is not screwed or the bolt is not screwed is in risk is avoided; performing an unlocking operation on the battery in an unlocking direction with a torque less than a maximum locking torque after performing the locking operation; acquiring the rotating speed of the locking and unlocking mechanism along the unlocking direction; and determining whether the vehicle is allowed to drive away from the parking platform according to the rotating speed. In addition, trade power station still including setting up the vehicle lifting mechanism on parking platform, wherein, vehicle lifting mechanism can lift the vehicle to certain height from parking platform, also can drop back the vehicle to on the parking platform. When the bolts of the battery of the vehicle are not screwed down and the vehicle is required to be prohibited from driving away from the parking platform, the vehicle lifting mechanism does not lift the vehicle back to the parking platform, and the arrangement mode can further prevent the vehicle from driving away from the battery changing station under the condition that the bolts are not screwed down. Meanwhile, the control method can solve the problem that the vehicle is driven away from the parking platform without being screwed down by the bolts of the vehicle battery under various conditions. The method has good effect in the automatic locking and unlocking process or the manual locking and unlocking process of a special person/cloud background. In a word, the control method provided by the invention finally ensures that the vehicle can drive away from the parking platform only when the bolt of the battery is in a completely screwed state, and ensures the safety and reliability of vehicle driving.
So far, the technical solutions of the present invention have been described in connection with the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of the present invention is obviously not limited to these specific embodiments. Equivalent changes or substitutions of related technical features can be made by those skilled in the art without departing from the principle of the invention, and the technical scheme after the changes or substitutions can fall into the protection scope of the invention.
