The charging control method for a special vehicle provided by the embodiment of the present application is explained below by using a plurality of specific examples with reference to the drawings. Fig. 2 is a schematic flow chart of a charging control method for a special vehicle according to an embodiment of the present application, where the method may be executed by the vehicle-mounted charger of the special vehicle in fig. 1. As shown in fig. 2, the method includes:
s201, detecting whether a charging gun is inserted into a charging gun socket or not and whether an input alternating current exists in a vehicle-mounted charger or not.
The vehicle-mounted charger can simultaneously detect whether a charging gun is inserted into the charging gun socket or not and whether the vehicle-mounted charger has input alternating current or not, can also detect whether the charging gun is inserted into the charging gun socket or not firstly and then whether the vehicle-mounted charger has the input alternating current or not, can also detect whether the vehicle-mounted charger has the input alternating current or not firstly and then detects whether the charging gun is inserted into the charging gun socket or not. For example, the vehicle-mounted charger may detect a state of the charging gun socket interface, and determine whether the charging gun is inserted into the charging gun socket interface; whether the vehicle-mounted charger has input alternating current or not can be determined by collecting the input voltage of the alternating current input end of the vehicle-mounted charger.
S202, if the fact that the charging gun is inserted into the charging gun socket is detected, and the vehicle-mounted charger has an alternating current input, the electronic lock is controlled to perform locking action, so that the charging gun is locked in the locked state.
If the vehicle-mounted charger detects that the charging gun is inserted into the charging gun socket and the vehicle-mounted charger has alternating current input, the fact that a user inserts the charging gun and accesses alternating current can be determined, the electronic lock on the charging gun socket can be controlled to perform locking action, the electronic lock is in an locked state, the charging gun is locked, and the charging gun is prevented from being pulled out in the charging process. For example, after the vehicle-mounted charger detects that the charging gun is inserted into the charging gun socket, the self-checking of the charging function can be performed, preparation is made for charging, if the charging function is in the self-checking process, a fault is found, even if the charging gun is inserted into the charging gun socket and the vehicle-mounted charger has an alternating current input, the electronic lock cannot be controlled to perform a locking action, namely, the electronic lock is controlled to be in an unlocking state, charging in the fault state is avoided, and charging safety is guaranteed. Illustratively, the self-test of the charging function includes at least one of the following self-test contents: the method comprises the steps of type identification of a charging gun, charging mode identification, software and hardware matching and charging parameter calibration.
And S203, charging when the electronic lock is in the locked state.
When the electronic lock is in the locked state, the charging gun is inserted into the charging gun socket, and the vehicle-mounted charger also has an alternating current input, so that the special vehicle can be charged. Because before charging, the electronic lock is already in a locking state to lock the charging gun, the electronic lock is ensured to be in a stable state in the charging process, the charging gun is always connected with the charging gun socket, dangerous conditions that the charging gun is separated from the charging gun socket and the like in the charging process cannot occur, and the personal safety of a user is practically guaranteed. The charging control method for the special vehicle comprises the steps of firstly detecting whether a charging gun is inserted into a charging gun socket or not and whether an input alternating current exists in a vehicle-mounted charger or not; when the charging gun is inserted into the charging gun socket and the vehicle-mounted charger has alternating current input, controlling the electronic lock to perform locking action and be in an locked state; and when the electronic lock is in the locked state, charging is carried out. Therefore, the charging gun is inserted into the charging gun socket, and the vehicle-mounted charger is controlled to lock the charging gun to start charging under the condition that the vehicle-mounted charger has alternating current input, so that the charging gun cannot be separated from the charging socket in the charging process, and the personal safety of a user is guaranteed.
On the basis of the charging control method for the special vehicle described in fig. 2, the embodiment of the present application further provides another charging control method for the special vehicle. Fig. 3 is a schematic flow chart of another charging control method for a special vehicle according to an embodiment of the present application. As shown in fig. 3, the method may further include:
s301, if the fact that the charging gun is inserted into the charging gun socket is detected, the vehicle-mounted charger does not have alternating current input, and the electronic lock is controlled to be in an unlocking state.
If the vehicle-mounted charger detects that the charging gun is inserted into the charging gun socket, but the vehicle-mounted charger does not have alternating current input, namely alternating current is not accessed, the charging cannot be carried out temporarily, and therefore the electronic lock can be controlled to be in the unlocking state. At the moment, the vehicle-mounted charger does not have alternating current input, a user can insert and pull the charging gun, and the danger of live operation cannot be caused, so that the charging gun does not need to be locked under the condition, and the electronic lock is controlled to be in an unlocking state.
Optionally, the method may further include:
s302, if it is detected that the charging gun is not inserted into the charging gun socket, the electronic lock is controlled to be in an unlocking state.
If the vehicle-mounted charger detects that the charging gun is not inserted into the charging gun socket, no matter whether a user accesses the alternating current or not, the charging condition is not met, charging cannot be carried out, the danger of live operation cannot be caused, the charging gun does not need to be locked, and the electronic lock is continuously controlled to be in the unlocking state.
According to the charging control method for the special vehicle, when the fact that the charging gun is inserted into the charging gun socket is detected, and the vehicle-mounted charger does not have alternating current input, the electronic lock is controlled to be in an unlocking state; and when the fact that the charging gun is not inserted into the charging gun socket is detected, the electronic lock is controlled to be in an unlocking state. In an actual scene, under the condition that a charging gun is inserted into a charging gun socket but an on-board charger does not have alternating current input, if the electronic lock is controlled to be in an locked state but a user changes the charging intention, the charging gun is pulled out before the alternating current input exists, and the electronic lock is locked at the moment, so that inconvenience is caused to the operation of the user; under the condition that the rifle that charges is not inserted on the rifle socket that charges, if control electronic lock is in the lock attitude, when needs charge next time, the user can't insert the rifle that charges in the socket that charges, causes the unable normal use of user to charge the rifle. Therefore, under the condition that the charging gun is inserted into the charging gun socket but the vehicle-mounted charger does not have alternating current input, or under the condition that the charging gun is not inserted into the charging gun socket, the electronic lock does not need to lock the charging gun, and the electronic lock is convenient for a user to operate under the condition that the safety of the user is guaranteed.
On the basis of the charging control method for the special vehicle shown in fig. 2, the embodiment of the application further provides a charging control method for the special vehicle after charging is completed.

And if the vehicle-mounted charger detects that the charging is finished, the output is closed, and the output charging of the storage battery and the electric equipment in the special vehicle is stopped.
And S403, detecting whether the vehicle-mounted charger has alternating current input.
After stopping charging, whether the vehicle-mounted charger has alternating current input or not is detected, namely whether alternating current is transmitted between the vehicle-mounted charger and a charging gun connected with a charging gun plug or not is detected.
And S404, if the vehicle-mounted charger does not have alternating current input, controlling the electronic lock to execute an unlocking action so as to unlock the charging gun.
If the vehicle-mounted charger is detected not to have alternating current input, namely no alternating current transmission exists between the vehicle-mounted charger and the charging gun connected with the charging gun plug, the electronic lock can be controlled to execute unlocking action so as to unlock the charging gun. At the moment, the whole charging process is completed, the vehicle-mounted charger does not have alternating current input, namely, the charging gun is not electrified, after the electronic lock is unlocked, the dangerous condition of the charged operation of a user can not occur, and the further operation of the charging gun after the charging is completed by the user can be facilitated.
According to the charging control method for the special vehicle after charging, in the charging process, the vehicle-mounted charger detects whether charging is finished; under the condition of finishing charging, the output is closed to stop charging; continuously detecting whether the vehicle-mounted charger has alternating current input; and under the condition that the vehicle-mounted charger is detected not to have the alternating current input, the electronic lock is controlled to execute the unlocking action and is in the unlocking state. When the vehicle-mounted charger does not have the input alternating current, the electronic lock can be unlocked, so that a user does not pull out a gun, and personal safety of the user is further guaranteed. After accomplishing the back that charges, stop alternating current input, the rifle that charges and on-vehicle machine that charges have not had alternating current transmission, and the rifle that charges is uncharged, does not have the risk of user live operation, and the user also need be followed the rifle socket that charges and drew out the rifle that charges simultaneously, consequently, can remove the locking to the rifle that charges, under the circumstances of guaranteeing user's safety, made things convenient for user's normal operating.
