Detailed Description
The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
Fig. 1 is a schematic architecture diagram of a vehicle control system according to an embodiment of the present application. The vehicle control system may include a charging stake server 101, a charging stake 102, a charging gun 103, a charging control device 104, a vehicle 105, and a vehicle server 106. The charging pile server 101 may obtain information about the charging pile 102 and manage the charging pile 102. For example, the charging pile server 101 may acquire the use condition (in a charged state or in an idle state) of each charging gun of the charging pile 102, so that each charging gun of the charging pile 102 may be managed. The charging stake 102 may include one or more charging guns, and the charging stake 102 shown in fig. 1 shows only one charging gun 103, as an example and not limiting of the application. The charging gun 103 is used to charge the vehicle 105. The vehicle 105 includes a vehicle charging interface that may be coupled to the charging gun 103 to charge the vehicle. The vehicle server 106 may acquire information about the vehicle 105 and manage the vehicle 105. For example, the vehicle server 106 may obtain a state of charge of the vehicle and determine whether the vehicle is charged based on the state of charge of the vehicle. The charging control device 104 is an apparatus for connecting a charging gun and a charging interface of a vehicle according to an embodiment of the present application. The charging control device 104 can bi-directionally confirm the charging pile and the vehicle charging state information, and can acquire the charging state of the vehicle more timely. It is understood that the charge control device 104 may be a device separate from the vehicle and the charge gun, or may be coupled to the vehicle (e.g., mounted on the vehicle), or may be coupled to 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 application. The charge control device 104 may include: guan Jiesuo device 104a and communication module 104b. The locking and unlocking device comprises a first end and a second end which are opposite, and the first end and the second end are respectively connected with the vehicle and the charging gun. For example, the Guan Jiesuo device 104a shown in fig. 2 includes a first end coupled to the vehicle and a second end coupled to the charging gun. Guan Jiesuo device 104a can be used to connect a vehicle (e.g., to connect a charging interface of the vehicle) to a charging gun on a charging stake and to perform a closing and unlocking operation on the vehicle and charging gun. The communication module 104b may be used to confirm information on a state of charge (in charge or completion of charge) between the vehicle and a charging post (charging gun), a time required for the 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 above-described vehicle control system includes: the charging pile server 101 is connected to the charging pile 102, the charging pile 102 is connected to the charging gun 103, the charging control device 104 is mounted on the vehicle 105 (the first end is connected to the vehicle 105), the vehicle 105 is connected to the charging gun 103 (the second end of the charging control device 104 is connected to the vehicle 105), and the vehicle 105 is connected to the vehicle server 106.
In another possible implementation, the charge control device 104 is not an in-vehicle device. For example, the charge control device 104 may be mounted on the charging gun 103. In this case, the connection relationship between the respective devices in the above-described vehicle control system includes: the charging pile server 101 is connected to the charging pile 102, the charging pile 102 is connected to the charging gun 103, the charging control device 104 is mounted on the charging gun 103 (the second end is connected to the charging gun 103), the charging gun 103 is connected to the vehicle 105 (the first end through the charging control device 104 is connected to the vehicle 105), and the vehicle 105 is connected to the vehicle server 106.
In yet another possible implementation, the charging control device is not an in-vehicle device nor is it mounted on the charging gun 103 as a stand-alone device. In this case, the connection relationship between the respective devices in the above-described vehicle control system 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 gun 103 is connected with the second end of the charging control device 104, the vehicle 105 is connected with the first end of the charging control device 104, and the vehicle 105 is connected with the vehicle server 106.
The charge control device 104 may obtain the charge state of the vehicle 105, the time required for charging, information of the vehicle 105, information of the charging pile 102, and the like from the charging pile server 101 and the vehicle server 106. Further, it is possible to realize that the charging gun 103 can be automatically released after the completion of charging of the vehicle 105 without waiting for the vehicle owner to unlock the vehicle 105.
Embodiments of the present application will be described in detail below with reference to the accompanying drawings.
Fig. 3 is a flow chart of a charging control method according to an embodiment of the present application. The charge control method shown in fig. 3 is performed by the charge control device, and the method may include the steps of:
s101, acquiring the charging state of the vehicle.
The state of charge of the vehicle may include: a state in which the vehicle charge has been completed, or a state in which the vehicle charge has not been completed. Wherein the state of charge may be expressed as a percentage of the amount of electricity. For example, the state of charge completion may be that the current amount of electricity is 100% of the total amount of electricity. The state of charge incompletion may be 50% of the current charge, 30% of the total charge, or the like.
In an alternative embodiment, acquiring the charge state information of the vehicle may include: charge state information of the vehicle is received 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 power information of the vehicle, kilometer number information that the vehicle can travel, time information required for charging completion, model information of the vehicle, and the like. For example, when the state of charge information of the vehicle includes current information, the state of charge of the vehicle may be determined based on the current information. Assuming that the current indicated by the current information is 10 amperes (a), it indicates that the vehicle is currently being charged, that is, that the charging state of the vehicle is a charging incompletion 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 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 embodiment of the application is not limited.
Alternatively, the acquiring of the state of charge of the vehicle may also be based on receiving state of charge information of the vehicle sent from an in-vehicle application (also referred to as in-vehicle application, in-vehicle APP). The vehicle-mounted application may be a default application related to vehicle charging of a vehicle system, or an application related to vehicle charging manually downloaded on an intelligent terminal, and the present application is not limited in specific embodiments.
In an alternative embodiment, acquiring the charge state information of the vehicle may include: charge status information of a vehicle from a charging stake is received. For example, the charging control device may send a request message to the charging stake and/or the vehicle at a preset period, the request message being for requesting acquisition of charging state information of the vehicle. For example, a keep heartbeat mechanism in the message queuing transmission (Message Queuing Telemetry Transport, MQTT) protocol is utilized, according to which a request message is sent to a charging peg connected to a charging gun and/or a vehicle to request acquisition of charging state information of the vehicle. Correspondingly, the charging stake and/or the vehicle may feed back a response message to the charging control device, the response message including the charging state information of the vehicle. For example, the response message may include, but is not limited to, current information, voltage information, current power information of the vehicle, kilometer that the vehicle can travel information, time information required for charging completion, model information of the vehicle, location information of the charging post, the number of charging guns of the charging post, voltage or current information corresponding to the charging gun, 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 peg and/or the vehicle at every 3 minutes. When a response message is received, the response message includes a state of charge of the vehicle. For example, when the current indicated by the response message received in a certain period is 0A, it is determined that the charge state of the vehicle is the charge completion state.
In an alternative embodiment, acquiring the charge state information of the vehicle may include: and detecting a current parameter or a voltage parameter, and determining the charge state information of the vehicle according to the current parameter or the voltage parameter. For example, an induction module (such as a voltage sensor or a current sensor) is present in the charging control device, and may induce a current parameter and/or a voltage parameter flowing from the second end to the first end 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, acquiring the charge state information of the vehicle may include: and determining the charge state information of the vehicle according to the remaining time of the completion of the charging of the vehicle. For example, a timer is set for recording the time remaining for the vehicle to complete charging; and determining the charge state information of the vehicle according to the remaining time of the vehicle charge completion.
Alternatively, the setting of the timer may be a default setting of the system or may be manually set.
The record of the remaining time of the vehicle charging completion may be a constant speed decrease or a non-constant speed decrease, which is not limited in the present application.
For example, different remaining times may be preset to correspond to different amounts of power, and different amounts of power to correspond to different states of charge of the vehicle. The remaining time corresponding to the electric quantity duty ratio of the vehicle being 0% may be preset to be 60min. In which case the vehicle is in an unfinished state of charge. The remaining time corresponding to the electric quantity ratio of the vehicle being 50% can be preset to be 30min. In this case, the vehicle is also in a charge incomplete state. The remaining time corresponding to the electric quantity duty ratio of the vehicle being 100% may be preset to be 0min. In this case, the vehicle is in a charge completion state.
For another example, assuming that the time remaining after the current charge of the vehicle recorded by the timer is 30 minutes, the state of charge of the vehicle is indicated as a charge incomplete state. Assuming that the time remaining after the current charge of the vehicle recorded by the timer is 0 minutes, the state of charge of the vehicle is indicated as the charge completion state.
And S102a, if the charging state information is charging completion information, controlling the switch unlocking device to disconnect the connection with the vehicle and/or the charging gun.
According to the description of the charge control device in fig. 2, the charge control device may control the off-unlocking means to disconnect the connection with the vehicle and/or the charging gun by: the locking and unlocking device is controlled to unlock the connecting parts of the first end and the vehicle and the connecting parts of the second end and the charging gun respectively.
For example, it is assumed that the charge control device is an in-vehicle apparatus. When the charging state of the vehicle is charging completion, the off unlocking means is controlled to unlock the connecting portion of the second end of the Guan Jiesuo device and the charging gun, and/or the off unlocking means is controlled to unlock the connecting portion of the first end of the Guan Jiesuo 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 off unlocking device is controlled to unlock the connecting part of the first end of the off unlocking device and the vehicle, and/or the connecting part of the second end of the off unlocking device and the charging gun.
And S102b, if the charging state information is charging start information, controlling the unlocking device to lock the connection with the vehicle and/or the charging gun.
According to the description of the charge control device in fig. 2, the charge control device controlling the lock of the lock-out means to the connection with the vehicle and/or the charging gun may be: the closing and unlocking means is controlled to lock the first end of the closing and unlocking means and the connecting portion of the vehicle, and lock the second end and the connecting portion of the charging gun, respectively. In this case, the vehicle and the charging gun can be fixedly connected, so that it is ensured that charging cannot be interrupted due to human factors in the charging process, and the vehicle is influenced.
According to the embodiment of the application, the charging state of the vehicle is obtained, and when the charging state of the vehicle is judged to be the charging completion, the unlocking device is controlled to unlock the connecting part between the vehicle and the charging gun so as to enable the charging gun to be 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 information of the charging pile and the state information of the vehicle charging can be confirmed and fed back in a two-way manner, so that the charging gun can be automatically released without waiting for a vehicle owner to unlock the vehicle after the vehicle charging is completed, and other vehicles can be charged in time conveniently.
Fig. 4 is a flowchart of another charge control method according to an embodiment of the present application, where the method may include the following steps:
s201, when the charging gun is detected to be connected with the vehicle, the first end of the control switch unlocking device is locked to be connected with the vehicle.
Specifically, when it is detected that the charging gun is connected to the vehicle, it may be that indication information is received from the charging pile server, the indication information being used to indicate that the charging gun is connected to the vehicle. For example, the indication information may be a current signal. When the current signal is detected, it indicates that the charging gun has been switched into the vehicle. According to the indication information, the first end of the control switch unlocking means locks the vehicle, i.e. indicates that the charging control device is locked on the vehicle, as shown in fig. 5 a.
It will be appreciated that other indication information may be detected, indicating that a charging gun is detected as being connected to the vehicle. For example, receiving a voltage signal indicates that the charging gun has been connected to the vehicle, and then controlling the first end of the locking/unlocking device to lock the vehicle, and the present application is not limited by the specific implementation manner.
And S202, when the charging gun is detected to start charging the vehicle, controlling 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 may be detected. For example, when the current indicated by the current information of the vehicle is greater than or equal to a preset current threshold value during charging of the vehicle, the charging gun is indicated to start charging of the vehicle. In this case, the second end of the off-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 control switch locks the second end of the unlocking means to the charging gun as shown in fig. 5 a.
It will be appreciated that in steps 201 and 202 described above, when the first end of the unlocking means is locked to the vehicle, if the vehicle is also locked, the charge control device is locked to the vehicle, and the charge control device cannot be removed from the vehicle when the vehicle is not unlocked. However, in this case, the charging gun is removable from the vehicle if it is not locked to the second end of the unlocking means. For example, if the vehicle is not required to be charged at this time, the charging gun may be removed from the vehicle for charging other vehicles. When the first end of the off unlocking means is locked with the vehicle and the second end is locked with the charging gun, then the charging control device is locked with both the charging gun and the vehicle. At this time, no matter whether the vehicle is unlocked or not, the charging gun cannot be taken down from the vehicle, so that the safety problem caused by the fact that the charging gun is pulled out when the vehicle is charged is avoided.
And S203, when the completion of the charging of the vehicle is detected, a charging completion message is sent to the charging pile and/or the vehicle.
Specifically, when the state of charge of the vehicle is detected as the charge completion state, it may be that the information about the vehicle satisfies the charge completion condition. For example, assume that the preset kilometer threshold of the vehicle is 500 Kilometers (KM). And if the kilometer information which can be driven by the vehicle is detected to be 500KM, sending a charging completion message to the charging pile and/or the vehicle. The charging completion message is used for indicating that the vehicle is charged. The charge completion message may include, but is not limited to, current information, voltage information, current power information of the vehicle, kilometer that the vehicle can travel information, time information required for the charge to complete, and the like. For example, the charge completion message includes kilometer information that the vehicle can travel as 500KM, indicating that the vehicle has been charged.
And 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.
The charging completion response message is used for confirming that the vehicle is charged. That is, when the charge control device determines that the charging is completed, it is also necessary to confirm again to the charging pile and the vehicle whether the charging is completed. After receiving the charging completion response message sent by the charging pile and the vehicle, it may be determined that charging is completed. For example, the charge completion response message may be a confirmation message including 500KM for which the vehicle confirms that the current vehicle can travel kilometers. In this case, the control-off unlocking means unlocks the connecting portion of the vehicle and the charging gun. For example, a first end of the control lock release means is unlocked from the vehicle and a second end of the control lock release means is unlocked from the charging gun, as shown in fig. 5 b.
And S204b, if a 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 pile receives the charging completion message, it detects that the output current of the charging gun is not 0A. The charging post does not send a charging completion response message indicating that the current charging gun is still charging the vehicle. In this case, the connection of the first end of the off-unlocking means to the vehicle and the connection of the second end of the off-unlocking means to the charging gun are not unlocked, so that the situation that the charging gun is pulled out when charging is not completed is avoided.
In the charging process of the vehicle, the locking and unlocking device in the charging control device can lock the vehicle and the charging gun, so that the on-site occurrence of load outage caused by human factors can be effectively avoided, and the charging safety is improved. By monitoring the vehicle charging information in real time, the state information of the charging pile and the state information of the 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.
