The charging control device 104 can confirm the charging pile and the charging state information of the vehicle in a two-way manner, and can acquire the charging state of the vehicle in a more timely manner. It is to be appreciated that the charge control device 104 can be a device separate from the vehicle and the charge gun, or can be coupled with the vehicle (e.g., mounted on the vehicle), or can be coupled with the charge gun (e.g., mounted at the charge gun port). For example, the charge control device shown in fig. 1 is mounted on a vehicle. After the vehicle is charged, the two ends of the charging control device can be respectively unlocked and connected with the charging gun and the vehicle, so that the charging gun can be automatically released, and other vehicles can be conveniently charged in time.
For example, fig. 2 is a schematic structural diagram of a charging control device 104 according to an embodiment of the present disclosure. The charge control device 104 may include: the locking and unlocking device 104a and the communication module 104b are turned on and off. Wherein the locking and unlocking device comprises opposite first and second ends, the first and second ends being connected to the vehicle and the charging gun, respectively.

The off-lock device 104a may be used to connect the vehicle (e.g., to connect a charging interface of the vehicle) to a charging gun on the charging post, and perform an off-lock operation on the vehicle and the charging gun. The communication module 104b may be configured to confirm information such as a charging state (in-charging or charging completion) between the vehicle and the charging pile (charging gun), a time required for completing charging of the vehicle, and the like.
In one possible implementation, the charge control device 104 may be an in-vehicle device (i.e., the charge control device 104 is mounted on the vehicle 105). In this case, the connection relationship between the respective devices in the vehicle control system described above includes: the charging pile server 101 is connected with the charging pile 102, the charging pile 102 is connected with the charging gun 103, the charging control device 104 is installed on the vehicle 105 (the first end is connected with the vehicle 105), the vehicle 105 is connected with the charging gun 103 (the second end of the charging control device 104 is connected with the vehicle 105), and the vehicle 105 is connected with the vehicle server 106.
In another possible implementation, the charging control device 104 is not an in-vehicle device. For example, the charging control device 104 may be mounted on the charging gun 103. In this case, the connection relationship between the respective devices in the vehicle control system described above includes: the charging pile server 101 is connected with the charging pile 102, the charging pile 102 is connected with the charging gun 103, the charging control device 104 is installed on the charging gun 103 (the second end is connected with the charging gun 103), the charging gun 103 is connected with the vehicle 105 (the first end of the charging control device 104 is connected with the vehicle 105), and the vehicle 105 is connected with the vehicle server 106.
In another possible implementation, the charging control device is not an on-board device and is not mounted on the charging gun 103, and is a separate device. In this case, the connection relationship between the respective devices in the vehicle control system described above includes: the charging pile server 101 is connected with a charging pile 102, the charging pile 102 is connected with a charging gun 103, the charging gun 103 is connected with a second end of a charging control device 104, a vehicle 105 is connected with a first end of the charging control device 104, and the vehicle 105 is connected with a vehicle server 106.

Further, it is possible to realize automatic release of the charging gun 103 without waiting for the owner to unlock the vehicle 105 after the charging of the vehicle 105 is completed.
The embodiments of the present application will be described in detail below with reference to the accompanying drawings.
Fig. 3 is a flowchart illustrating a charging control method according to an embodiment of the present disclosure. The charging control method shown in fig. 3 is executed by the charging control apparatus, and may include the steps of:
and S101, acquiring the charging state of the vehicle.
The state of charge of the vehicle may include: a state where vehicle charging is completed, or a state where vehicle charging is not completed. Wherein the state of charge may be expressed as a percentage of the amount of electricity used. For example, the state of charge completion may be that the current charge accounts for 100% of the total charge. The state of incomplete charging may be that the current amount of electricity occupies 50% of the total amount of electricity, that the current amount of electricity occupies 30% of the total amount of electricity, and so on.
In an alternative embodiment, obtaining the charge state information of the vehicle may include: receiving charge state information of the vehicle from a vehicle server. For example, the charge state information of the vehicle from the vehicle server may include, but is not limited to, current information, voltage information, current charge amount information of the vehicle, kilometer number information that the vehicle can make, time information required for completion of charging, model information of the vehicle, and the like. For example, when the charge state information of the vehicle includes current information, the charge state of the vehicle may be determined based on the current information. When the current indicated by the current information is 10 amperes (a), it indicates that the current vehicle is charging, that is, the charging state of the vehicle is a charging incomplete state. Assuming that the current indicated by the current message is 0A, it indicates that the vehicle is not charged, i.e., the charging state of the vehicle is a charging completion state. The state of charge of the vehicle may be determined based on other information from the vehicle server. For example, the vehicle server directly sends the first indication information to the vehicle, where the first indication information is used to indicate that the charging state of the vehicle is a charging incomplete state or a charging complete state, and the specific embodiment is not limited in this application.
Alternatively, the charging state of the vehicle may be acquired based on receiving charging state information of the vehicle transmitted from an in-vehicle application (also referred to as an in-vehicle APP). The vehicle-mounted application may be a default application related to vehicle charging of a vehicle system, or may be an application related to vehicle charging that is downloaded manually on an intelligent terminal, and the specific embodiment is not limited in this application.
In an alternative embodiment, obtaining the charging state information of the vehicle may include: and receiving charging state information of the vehicle from the charging pile. For example, the charging control device may send a request message for requesting to acquire charging state information of the vehicle to the charging post and/or the vehicle at a preset cycle. For example, a keepalive heartbeat mechanism in a Message Queuing transmission (MQTT) protocol is utilized, and a request Message is sent to a charging pile and/or a vehicle connected with a charging gun according to the heartbeat mechanism to request to acquire charging state information of the vehicle. Correspondingly, the charging pile and/or the vehicle can feed back a response message to the charging control device, wherein the response message comprises charging state information of the vehicle. For example, the response message may include, but is not limited to, current information, voltage information, current capacity information of the vehicle, kilometer number information of the vehicle, time information required for completion of charging, model information of the vehicle, position information of the charging post, the number of charging guns of the charging post, voltage or current information corresponding to the charging guns, and the like. In addition, the preset period may be a manually set time period or a system default time period. For example, the period may be 3 minutes.
For example, assuming that the preset period is 3 minutes, the charging control device transmits a request message to the charging pile and/or the vehicle at intervals of 3 minutes. When the response message is received, the response message includes the state of charge of the vehicle. For example, when the response message received in a certain period indicates a current of 0A, the state of charge of the vehicle is determined to be a charge complete state.
In an alternative embodiment, obtaining the charge state information of the vehicle may include: and detecting the current parameter or the voltage parameter, and determining the charging state information of the vehicle according to the current parameter or the voltage parameter. For example, a sensing module (e.g., a voltage sensor or a current sensor) is present in the charging control device, and may sense a current parameter and/or a voltage parameter flowing from the second terminal to the first terminal of the charging control device, and generate the charging state information according to the current parameter and/or the voltage parameter.
In an alternative embodiment, obtaining the charge state information of the vehicle may include: and determining the charging state information of the vehicle according to the time left by the vehicle charging. For example, a timer is set for recording the time remaining until the vehicle is charged; and determining the charging state information of the vehicle according to the time left after the vehicle is charged.
Optionally, the setting of the timer may be a default setting of the system, or may be manually set.
The recording of the remaining time of the vehicle charging completion may be a constant speed reduction or a non-constant speed reduction, which is not limited in the present application.
For example, different remaining times may be preset for different amounts of power, and different amounts of power correspond to different states of charge of the vehicle. The remaining time corresponding to 0% of the electric quantity of the vehicle may be set in advance to 60 min. In this case, the vehicle is in a state in which charging is incomplete. The remaining time corresponding to the electric quantity of the vehicle accounting for 50% may also be set in advance to 30 min. In this case, the vehicle is also in a state of charge incompletion. The remaining time corresponding to the capacity of the vehicle being 100% may also be set in advance to 0 min. In this case, the vehicle is in a charge complete state.
For another example, if the time remaining after the current charging of the vehicle recorded by the timer is 30 minutes, it indicates that the charging state of the vehicle is a charging uncompleted state. It is assumed that the time remaining after the current charging of the vehicle recorded by the timer is 0 minute indicates that the state of charge of the vehicle is the charging completion state.
And S102a, if the charging state information is charging completion information, controlling the unlocking device to be disconnected with the vehicle and/or the charging gun.
According to the description of the charging control apparatus in fig. 2, the control of the charging control apparatus to disconnect the off-lock device from the vehicle and/or the charging gun may be: and controlling the closing and unlocking device to respectively unlock a connecting part of a first end of the closing and unlocking device and the vehicle and unlock a connecting part of a second end and the charging gun.
For example, it is assumed that the charge control device is an in-vehicle apparatus. And when the charging state of the vehicle is charging completion, controlling the second end of the locking and unlocking device to unlock the connecting part of the second end of the locking and unlocking device and the charging gun, and/or controlling the first end of the locking and unlocking device to unlock the connecting part of the first end of the locking and unlocking device and the vehicle.
For another example, it is assumed that the charge control device is not an in-vehicle device. When the charging state of the vehicle is charging completion, the connection part of the first end of the locking and unlocking device and the vehicle is controlled to be unlocked by the locking and unlocking device, and/or the connection part of the second end of the locking and unlocking device and the charging gun is controlled to be unlocked by the locking and unlocking device.
And S102b, if the charging state information is charging starting information, controlling the locking and unlocking device to lock the connection between the vehicle and/or the charging gun.
According to the description of the charging control apparatus in fig. 2, the connection between the locking and unlocking means lock and the vehicle and/or the charging gun may be controlled by the charging control apparatus: and controlling the closing and unlocking device to respectively lock the first end of the closing and unlocking device and the connecting part of the vehicle, and lock the second end and the connecting part of the charging gun. Under this condition, can make vehicle and the rifle fixed connection that charges to guarantee can not cause the influence to the vehicle because of human factor interruption charging in the charging process.
According to the charging gun control method and device, the charging state of the vehicle is obtained, and when the charging state of the vehicle is judged to be charging completion, the connection part between the vehicle and the charging gun is controlled to be unlocked through the locking and unlocking device, so that the charging gun is in an idle state. By adopting the charging control method, the vehicle charging interface and the charging gun can be connected, and the real-time state message of the charging pile and the vehicle charging state message can be confirmed and fed back in a two-way mode, so that the charging gun can be automatically released without waiting for a vehicle owner to unlock the vehicle after the vehicle charging is finished, and other vehicles can be charged conveniently in time.
Fig. 4 is a schematic flowchart of another charging control method according to an embodiment of the present disclosure, where the method includes the following steps:
s201, when the charging gun is detected to be connected to the vehicle, the first end of the unlocking device is controlled to be locked and connected with the vehicle.
Specifically, when it is detected that the charging gun is connected to the vehicle, the charging gun may receive indication information from the charging pile server, where the indication information is used to indicate that the charging gun is connected to the vehicle. For example, the indication may be a current signal. When the current signal is detected, the charging gun is connected to the vehicle. According to the instruction information, the first end of the unlocking means is controlled to lock the vehicle, that is, the charging control device is locked on the vehicle, as shown in fig. 5 a.
It is understood that other indication information may be detected to indicate that the charging gun is detected to be connected to the vehicle. For example, a voltage signal is received, which indicates that the charging gun has been connected to the vehicle, and then the first end of the unlocking device is controlled to lock the vehicle.
S202, when the charging gun is detected to start charging the vehicle, controlling to close the second end of the unlocking device to lock the connection with the charging gun.
Specifically, when the charging gun is detected to start charging the vehicle, the current or voltage information of the vehicle can be detected. For example, when the current indicated by the current information of the vehicle is greater than or equal to the preset current threshold value during charging of the vehicle, it indicates that the charging gun starts charging the vehicle. In this case, the second end of the closing and unlocking means is controlled to lock the charging gun. For example, assume that the preset current threshold is 2A. When the current indicated by the current information of the vehicle is detected to be 5A, the charging gun is indicated to start charging the vehicle. In this case, the second end of the locking and unlocking means is controlled to lock the charging gun, as shown in fig. 5 a.
It is understood that, in the above steps 201 and 202, when the first end of the unlocking means is locked with the vehicle, if the vehicle is also locked, the charging control device is locked on the vehicle, and the charging control device cannot be removed from the vehicle if the vehicle is not unlocked. However, if the charging gun is not locked with the second end of the off-lock release device, the charging gun can be removed from the vehicle. For example, if the vehicle does not need to be charged for the moment, the charging gun can be removed from the vehicle for charging other vehicles. When the first end of the locking and unlocking device is locked with the vehicle and the second end is locked with the charging gun, the charging control device is locked with the charging gun and the vehicle. No matter whether the vehicle is unlocked at this moment, the charging gun can not be taken down from the vehicle, so that the safety problem caused by pulling the charging gun down when the vehicle is charged is avoided.
And S203, when the vehicle charging is detected to be completed, sending a charging completion message to the charging pile and/or the vehicle.
Specifically, when it is detected that the state of charge of the vehicle is a charge completion state, it may be that the relevant information of the vehicle satisfies the charge completion condition. For example, assume that the preset kilometer threshold for the vehicle is 500 Kilometers (KM). And if the detected kilometer number information that the vehicle can run is 500KM, sending a charging completion message to the charging pile and/or the vehicle. Wherein the charging completion message is used to indicate that the vehicle charging is complete. The charge completion message may include, but is not limited to, current information, voltage information, current charge amount information of the vehicle, kilometer number information that the vehicle can perform, time information required for completion of charging, and the like. For example, the charging completion message includes information on the number of kilometers that the vehicle can travel at 500KM, indicating that the charging of the vehicle is completed.
S204a, if a charging completion response message sent by the charging pile and the vehicle is received, controlling the unlocking device to unlock the connection between the first end and the vehicle and the connection between the second end and the charging gun.
Wherein the charging completion response message is used to confirm that the vehicle charging is complete. That is, when the charging control means determines that charging is completed, it is also necessary to confirm again to the charging pile and the vehicle whether charging is completed. After receiving the charging completion response message sent by the charging pile and the vehicle, it can be determined that the charging is completed. For example, the charge completion response message may be a confirmation message including that the vehicle confirms that the current kilometer-worth information that the vehicle can run is 500 KM. In this case, the control-off unlocking means unlocks the connection portion of the vehicle and the charging gun. For example, a first end of the off-lock release device is controlled to be unlocked from the vehicle, and a second end of the off-lock release device is controlled to be unlocked from the charging gun, as shown in fig. 5 b.
S204b, if the charging completion response message sent by the charging pile and the vehicle is not received, controlling the unlocking device to keep locking the connection between the first end and the vehicle and the connection between the second end and the charging gun.
For example, if the charging post receives the charging completion message, it is detected that the output current of the charging gun is not 0A. Then the current charging gun is still charging the vehicle, and the charging pile will not send a charging completion response message. In this case, the connection of the first end of the on/off locking/unlocking device to the vehicle and the connection of the second end of the on/off locking/unlocking device to the charging gun are not unlocked, thereby avoiding the situation that the charging gun is pulled out when the charging is not completed.
In the charging process of the vehicle, the vehicle and the charging gun can be locked by a locking and unlocking device in the charging control device, the field occurrence of on-load power failure caused by human factors can be effectively avoided, and the charging safety is improved. Through the real-time monitoring to the vehicle charging message, the state message of charging pile and the state message of vehicle charging can be confirmed and fed back in real time. Therefore, after the vehicle is charged, the charging gun can be automatically released without waiting for the vehicle owner to unlock the vehicle, and other vehicles can be charged in time conveniently.
It should be understood that although the steps in the flowcharts of fig. 3 and 4 are shown in order as indicated by the arrows, the steps are not necessarily performed in order as indicated by the arrows. The steps are not limited to being performed in the exact order illustrated and, unless explicitly stated herein, may be performed in other orders.
