Technical Field
The invention relates to the technical field of vehicles, in particular to the technical field of electric vehicles.

Background
Currently, a user of an electric vehicle needs to perform many active operations when charging the electric vehicle. For example, when an electric vehicle attempts to charge at a charging post, a user of the electric vehicle must scan a two-dimensional code of the charging post to match the electric vehicle and the charging post. This is because there is not feasible communication channel between the electric vehicle and the charging pile in the current process of charging the electric vehicle through the charging pile, and if there is no process of scanning the two-dimensional code by the user, there is no way for the application program of the electric vehicle to know which specific charging pile to charge on, or for the charging pile to know which specific electric vehicle is charging. However, such a staking process is not only cumbersome and time consuming for the user.
Therefore, it is desirable to provide a simple and efficient pile driving method.

Detailed Description
In order to make the technical problems, technical solutions and advantageous effects of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings and exemplary embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and do not limit the scope of the invention.
Fig. 1 shows a schematic block diagram of a system 1 for determining a charging device that is physically engaged with a target vehicle according to an exemplary embodiment of the present invention. The system 1 comprises at least one vehicle-side device 2, at least one charging-apparatus-side device 3, and a server 4 communicatively connected to the vehicle-side device 2 and the charging-apparatus-side device 3.
The vehicle-side apparatus 2 is configured to transmit at least one of the following information to the server 4 after the vehicle to which it corresponds is physically engaged with one charging device: charging station identification information, current geographic location, engagement time, and type of charging interface engaged (e.g., ac/dc), etc. The charging device is designed, for example, as a charging post, in particular a utility charging post, with a charging gun, the physical engagement corresponding to the insertion of the charging connector of the charging gun into the charging interface of the vehicle. Also, the physical engagement of the charging device with the vehicle may be performed manually, partially automatically, or fully automatically.
The charging-apparatus-side device 3 is configured to be able to transmit at least one of the following information of the charging apparatus to the server 4: identity information, location information, operational status information (e.g., idle state, charging state, or, possibly, physically engaged but charging not enabled), interface type information (e.g., ac/dc), etc.
The server 4 includes a storage device 41 that stores a variety of information including those described above, which is collected over a time span, such as the past year, for example, from the vehicle-side apparatus 2 and the charging device-side apparatus 3. In an exemplary embodiment, a database is established based on at least the information collected from the charging device-side apparatus 3 to enable query, retrieval, update, modification, and addition/deletion of the charging device information.
Fig. 2 schematically illustrates a block flow diagram of a method for determining a charging device that is physically engaged with a target vehicle, according to an exemplary embodiment of the invention. As shown in fig. 2, in step S10, a charging device assigned to a charging station is selected as at least one first primary candidate charging device based on charging station identification information corresponding to the charging station from a target vehicle after the charging device is physically engaged with the target vehicle. Next, in step S20, a secondary candidate charging device that is likely to be physically engaging with the target vehicle is screened from the at least one first primary candidate charging device according to the screening condition. The screening condition may be, for example, a screening condition related to an operation state of the charging device or an interface type or the like. The charging station identification information represents identification information corresponding one-to-one to the charging station, such as a charging station identification code.
With the charging station identification information corresponding to the charging station, it is possible to quickly limit the range of the charging device that may be physically engaging with the target vehicle to the charging devices belonging to the charging stations identified by the charging station identification information, thereby reducing the time required to determine the charging device that is physically engaging with the target vehicle. In particular, the number of charging devices that need to be screened and the amount of data of information about the respective charging devices can be reduced.
The method for determining a charging device that is physically engaging with a target vehicle is further described below in conjunction with fig. 2 and 3. Fig. 3 shows an exemplary embodiment of the method according to the present invention implemented by the system 1 according to the present invention in a system flow diagram.
In the exemplary embodiment shown in fig. 3, the charging station identification information is determined by: and if the target vehicle takes the charging station as a navigation destination and the target vehicle enters a preset position range around the charging station, taking the identification information corresponding to the charging station as the charging station identification information. Thus, the charging station at which the target vehicle is located can be determined with high accuracy. In particular, when the target vehicle is located within some charging stations, the current geographic location of the target vehicle cannot be reliably determined, for example, due to GPS data being inaccurate under indoor conditions. When the target vehicle takes the charging station as a navigation destination and the target vehicle enters a predetermined position range around the charging station, it can be reliably determined that the target vehicle is charged in the charging station. The predetermined location range may be, for example, a parking lot or a geofence in which the charging station is located.
Furthermore, the charging station identification information may also be determined in other ways. For example, in another exemplary embodiment, if the target vehicle has a charging station as the navigation destination and the target vehicle is physically engaged with the charging apparatus within a first predetermined time after the charging station is set as the navigation destination of the target vehicle, identification information corresponding to the charging station is taken as charging station identification information. In still another exemplary embodiment, if the target vehicle is physically engaged with the charging apparatus within a second predetermined time after the target vehicle enters within a predetermined position range around the charging station, identification information corresponding to the charging station is taken as charging station identification information.
Referring to fig. 3, step S10 includes step S11 and step S12.
In step S11, after the charging device has completed physical engagement with the target vehicle, the vehicle-side apparatus 2 built in the target vehicle transmits charging station identification information and optionally information such as the current geographical position of the vehicle or the type of charging interface engaged to the server 4. Alternatively, the vehicle-side device 2 may transmit information such as the current geographical position of the vehicle, the type of the charging interface that is engaged, or the engagement time of the charging apparatus with the target vehicle, together with the charging station identification information, to the server 4. The current geographic location of the vehicle is, for example, the geographic location of the vehicle at the time of engagement as determined by GPS data. Information such as the type of charging interface being engaged or the engagement time of the charging device with the target vehicle may be used to screen secondary candidate charging devices in subsequent steps.
In step S12, the server 4 selects, as the first primary candidate charging devices, the charging devices, in particular all the charging devices, which belong to the charging station identified by the charging station identification information, based on the charging station identification information.
Then, in step S20, a secondary candidate charging device that may be physically engaging the target vehicle may be screened from the at least one first primary candidate charging device, based on, among other things, a screening condition related to an operating state of the charging device. In an exemplary embodiment, the screening condition satisfied by the secondary candidate charging device is: it changes from an idle state to a state in which charging is physically engaged but not initiated at a particular timestamp, wherein the timestamp corresponds to the point in time at which the charging device is physically engaged with the target vehicle.
According to an exemplary embodiment of the present invention, whether the charging device satisfies the screening condition is determined in the following manner: the last historical state recorded by the charging device prior to the timestamp is an idle state and after the timestamp is in a state of being physically engaged but charging is not initiated.
For this purpose, optionally, in step S30: obtaining a last historical status of the at least one first primary candidate charging device prior to the timestamp and their current real-time status. To this end, the server 4 may exemplarily send a data acquisition request to the charging apparatus-side device 3 to retrieve data about the real-time status and optionally the last historical status, as shown in fig. 3. Additionally or alternatively, the last historical state can be obtained by accessing the database, since the charging apparatus-side device 3 always sends relevant data to the server 4 either instantaneously or periodically.
According to an exemplary embodiment, the time point at which the server 4 receives the charging station identification information from the vehicle-side device 2 may be taken as the time stamp. Alternatively, the point of time of engagement of the charging device with the target vehicle, which is recorded by the vehicle-side apparatus 2, may be transmitted to the server 4 to serve as the time stamp. In this case, it may be necessary to synchronize clocks of the server 4, the vehicle-side apparatus 2, and the charging apparatus-side apparatus 3.
Next, the number of secondary candidate charging devices screened in step S20 is counted in step S30, and if the number of secondary candidate charging devices happens to be equal to 1, the unique secondary candidate charging device is considered to be the charging device that is physically connected to the target vehicle and then the charging process of the unique secondary candidate charging device is initiated (step S40). If the number of secondary candidate charging devices is not equal to 1, such as greater than 1 or equal to zero, it is determined that the charging device that is being physically engaged with the target vehicle has not been successfully determined (step S50). In this case, the user may be notified of the automatic matching failure and be informed of the need to manually match the charging device, for example, by scanning a QR code in step S60.
Alternatively, after the automatic matching fails, a list of all charging piles around the target vehicle may be provided to the user through a human-machine interface of the vehicle or the smartphone to let the user select which charging device the target vehicle is being connected to.
Fig. 4 schematically illustrates a block flow diagram of a method for determining a charging device that is physically engaged with a target vehicle, according to an exemplary embodiment of the invention. The method shown in fig. 4 has substantially the same steps S10, S20, S30, S40, S50 and S60 as the method shown in fig. 2, and the same steps can be referred to the description made above with reference to fig. 2 and will not be repeated herein.
In the embodiment shown in FIG. 4, step S70 is performed after step S20: it is determined whether the number of secondary candidate charging devices is equal to 0, wherein if the number is equal to 0, steps S80 and S90 are performed, and if the number is not equal to 0, step S30 is performed.
In step S80, at least one second primary candidate charging device is selected based on the current geographic location of the target vehicle. For this purpose, after the charging device has completed physical engagement with the target vehicle, the vehicle-side apparatus 2 built into the target vehicle may transmit the current geographical position of the vehicle (e.g. GPS data) and optionally the type of charging interface engaged to the server 4. Alternatively, the current geographical position of the vehicle may be transmitted (in step S11) to the server 4 together with the charging station identification information. The server 4 may then delineate a geographic range with reference to the current geographic location of the target vehicle and select all charging devices within that geographic range as second primary candidate charging devices. In an exemplary embodiment, all charging devices within the geographic range except the first primary candidate charging device are selected as the second primary candidate charging device, thereby avoiding repeated screening of the first primary candidate charging device. The geographic range should be defined to be large enough to accommodate positioning errors of the vehicle and charging device while necessarily including a charging device physically connected to the target vehicle. In one example, all charging devices within a preset threshold, e.g., 500 or 800 meters, from the current geographic location of the target vehicle are selected as the first primary candidate charging device. In another example, if the location data of the vehicle shows that it is within a parking lot or a geofence, all charging devices within the parking lot or the geofence are selected as the first primary candidate charging device.
Then, in step S90, a secondary candidate charging device that is likely to be physically engaging with the target vehicle is screened from the second primary candidate charging device according to the screening condition. Step S90 may be performed similarly to step S20.
After step S90 is performed, step S30 is continuously performed to determine whether the charging device that is being physically engaged with the target vehicle is successfully determined.
Although specific embodiments of the invention have been described herein in detail, they have been presented for purposes of illustration only and are not to be construed as limiting the scope of the invention. Various substitutions, alterations, and modifications may be devised without departing from the spirit and scope of the present invention.
