In order to avoid potential safety hazards caused by communication between the first vehicle 110 and the charging devices 120, the server 130 may be in communication connection with the vehicle-mounted terminal of the first vehicle 110, and the vehicle-mounted terminal of the first vehicle 110 may acquire information of the charging devices 120 or control the charging devices 120 through communication with the server 130, that is, the server 130 may also be in communication connection with a plurality of charging devices 120, so as to exchange information with the charging devices 120 respectively, for example, the server 130 may receive a charging request sent by the vehicle-mounted terminal of the first vehicle 110 and send a charging instruction to the charging devices 120 to control the charging devices 120 to start charging. In one embodiment, the vehicle-mounted terminal may configure a connection mode corresponding to the first vehicle 110 to control a connection state corresponding to the first vehicle 110, and acquire connection states corresponding to the plurality of charging devices 120 respectively, and determine a target charging device from the plurality of charging devices 120 according to the connection states corresponding to the plurality of charging devices 120 respectively and the connection mode, and then the vehicle-mounted terminal may send a charging request to the server 130 according to charging device information of the target charging device to instruct the server 130 to control the target charging device to start charging.

Optionally, the server 130 may include a vehicle server corresponding to the first vehicle 110 and charging servers corresponding to the plurality of charging devices 120, as shown in fig. 1-B, where fig. 1-B is a schematic application scenario of another vehicle charging method disclosed in the embodiment of the present application, where a vehicle terminal of the first vehicle 110 may be communicatively connected to a vehicle server 131, and the plurality of charging devices 120 may be communicatively connected to a charging server 132, and the vehicle server 131 may be communicatively connected to the charging server 132.

step 210, configuring a connection mode corresponding to the first vehicle as a target connection mode.

Step 220, obtaining connection states corresponding to the plurality of charging devices respectively.

When a user uses the charging device to charge the first vehicle, taking a wired charging mode as an example, the user can insert a charging gun of the charging device into a charging socket of the first vehicle, the vehicle-mounted terminal can detect that the charging gun is inserted into the charging socket of the first terminal, that is, the vehicle-mounted terminal can detect that the first vehicle is physically connected with the charging device, and in order to control a connection state corresponding to the first vehicle and also control a connection state corresponding to the charging device connected with the first vehicle while detecting that the first vehicle is physically connected with the charging device, the vehicle-mounted terminal can configure a connection mode corresponding to the first vehicle as a target connection mode. Optionally, before the first vehicle is physically connected to the charging device, that is, when the first vehicle is not physically connected to the charging device, the vehicle-mounted terminal may configure a connection mode corresponding to the first vehicle as the target connection mode. The embodiment of the application does not limit the configuration of the connection mode corresponding to the first vehicle, and only needs to enable the connection mode corresponding to the first vehicle to be the target connection mode after the first vehicle is physically connected with the charging equipment.

The connection mode is used for controlling the corresponding connection mode of the first vehicle. Alternatively, the vehicle terminal may configure the target connection mode to be the first mode to control the connection state corresponding to the first vehicle to be the unconnected state, and correspondingly, the connection state corresponding to the charging device connected to the first vehicle to be the unconnected state. Optionally, the vehicle terminal may also set the target connection mode to the second mode to control the connection state corresponding to the first vehicle to be the connected uncharged state, and correspondingly, the connection state corresponding to the charging device connected to the first vehicle is also the connected uncharged state.

Since the plurality of charging devices are usually included in the same location, the vehicle-mounted terminal needs to determine the charging devices connected with the first vehicle from the plurality of charging devices, the plurality of charging devices can be controlled by the server, when the first vehicle arrives at the same location corresponding to the plurality of charging devices, for example, a charging station, the vehicle-mounted terminal can establish communication connection with the server controlling the plurality of charging devices, and obtain connection states corresponding to the plurality of charging devices respectively through the server. The vehicle-mounted terminal can acquire connection states corresponding to the plurality of charging devices respectively under the condition that the first vehicle and the charging devices are detected to be physically connected.

Optionally, the vehicle-mounted terminal may send query request information to the server, where the query request information may be used to instruct the server to obtain connection states corresponding to the plurality of charging devices respectively, the server receives the query request information, may send the connection states corresponding to the plurality of charging devices respectively to the vehicle-mounted terminal, and the vehicle-mounted terminal may receive the connection states corresponding to the plurality of charging devices fed back by the server respectively. Alternatively, after the server establishes communication connection with the vehicle-mounted terminal, before the first vehicle starts charging, the server may send connection states corresponding to the plurality of charging devices respectively to the vehicle-mounted terminal every a preset period of time, for example, the server may send connection states corresponding to the plurality of charging devices respectively to the vehicle-mounted terminal every 2s (seconds).

In one embodiment, the vehicle-mounted terminal may determine, through map software, a charging station at which the first vehicle is currently located; or identifying the characteristics of the charging station for the target image acquired by the camera to determine the charging station where the first vehicle is currently located; or in the case of establishing a communication connection with a target device included in the charging station, determining, by the target device, the charging station in which the vehicle is currently located.

Optionally, the vehicle-mounted terminal may also be provided with a camera, and the camera may collect a target image of the surrounding environment, analyze the target image collected by the camera, and identify charging station features contained in the target image by using a computer vision technology, such as a convolutional neural network, where the charging station features may include an appearance shape of the charging device, a charging station identification board, a charging station two-dimensional code, and so on, so as to determine a charging station where the vehicle is located. Alternatively, the target device in the charging station may be any device included in the charging station, and the target device may send information of the charging station to the vehicle-mounted terminal communicatively connected to the target device, so that the vehicle-mounted terminal may determine the charging station where the first vehicle is currently located. The communication connection may include, but is not limited to, a bluetooth connection, a Wi-Fi (wireless network communication) connection, a ZigBee (ZigBee protocol) connection, and the like.

As an optional implementation manner, the vehicle-mounted terminal may also acquire current navigation information of the map software, and determine a charging station where the first vehicle is currently located according to the navigation information. The current navigation information of the map software may include a navigation route, a navigation destination, navigation prompt information, and the like, where the navigation prompt information may refer to prompt information output by the map software to various preset types of places that are about to arrive in the navigation process, for example, prompt that 5 km arrives at a service station on a highway.

Optionally, the vehicle-mounted terminal may determine a plurality of charging stations on the navigation route, and determine a charging station where the first vehicle is currently located from the plurality of charging stations, and optionally, when the navigation destination is a charging station, the vehicle-mounted terminal may also determine the charging station as the charging station where the first vehicle is currently located. Optionally, when the location indicated by the navigation prompt information is a location including a charging device, such as a charging station or a service station, the vehicle-mounted terminal may also use the location indicated by the navigation prompt information as the charging station where the first vehicle is currently located. By implementing the embodiment, the charging station where the first vehicle is currently located can be determined through the navigation information, so that the diversity and convenience of the method for acquiring the charging station where the first vehicle is currently located are improved.

As an alternative implementation manner, the vehicle-mounted terminal may also execute the charging station inquiring operation through the map software, and determine the charging station which is determined by the map software to be closest to the first vehicle as the charging station where the vehicle is currently located. The vehicle-mounted terminal executes the charging inquiry operation through the map software, and the map software acquires positioning information and returns the positioning information and the distances between each charging station and the first vehicle, so that the vehicle-mounted terminal can determine the charging station which is determined by the map software and is closest to the first vehicle as the charging station where the vehicle is currently located, the positioning information is only acquired by the map software, a user is not required to be informed or the charging station is transmitted to other places, and the data safety is improved.

In step 230, a target charging device that is physically connected to the first vehicle is determined from the plurality of charging devices according to the connection state corresponding to the first vehicle and the connection states corresponding to the plurality of charging devices, respectively.

The vehicle-mounted terminal may determine whether the connection state corresponding to the first vehicle is the same according to the connection states corresponding to the plurality of charging devices, so that a target charging device having the same connection state as the connection state corresponding to the first vehicle may be determined from the plurality of charging devices. Alternatively, the connection state may include a plurality of connection states, a change in connection state, or the like, which is not limited.

In one embodiment, the first vehicle may include a switching device for controlling a connection mode corresponding to the first vehicle, the target connection mode may include a first mode, the vehicle-mounted terminal may control the switching device to be turned on to configure the connection mode corresponding to the first vehicle as the first mode such that the connection state corresponding to the first vehicle is an unconnected state, the vehicle-mounted terminal may regard the charging device having the connection state as the target charging device, for example, when other charging devices of the charging station are all in use, the vehicle-mounted terminal may configure the connection mode as the first mode such that the connection state corresponding to the charging device connected to the first vehicle is the unconnected state and the other charging devices are connected to the unconnected state or the in-charge state, and the vehicle-mounted terminal may regard the charging device having the corresponding connection state as the target charging device. According to the embodiment, the switching device is arranged to configure the corresponding connection mode of the first vehicle to further control the connection of the first vehicle and the charging equipment, so that the target charging equipment which is physically connected with the first vehicle can be determined from a plurality of charging equipment, and accuracy and efficiency of determining the target charging equipment are improved.

In one embodiment, the first vehicle does not have a function of disconnecting from the connected charging device, i.e. the first vehicle may not include a switching device, and the target connection mode may include a second mode for controlling the corresponding connection state of the first vehicle to be the connected uncharged state. Determining a target charging device from the plurality of charging devices according to the connection states respectively corresponding to the plurality of charging devices, wherein the method comprises the following steps: a charging device whose connection state is a connected uncharged state is determined from among the plurality of charging devices as a target charging device that is physically connected to the first vehicle.

It will be appreciated that the first mode requires the first vehicle to have the capability of disconnecting from the connected charging device, whereas the second mode does not require the first vehicle to have the capability, so that when the charging gun of the charging device is plugged into the charging socket, the first vehicle may establish a connection with the charging device if the first vehicle does not have the capability of disconnecting from the connected charging device, the target connection mode may be considered as the second mode. Therefore, if the charging device connected to the first vehicle is in the connected uncharged state and the other charging device of the charging station is in the charging state or is not in use, the vehicle-mounted terminal may set the charging device whose corresponding connection state is in the connected uncharged state as the target charging device. By implementing the embodiment, the target charging equipment can be directly determined according to the corresponding connection state of the charging equipment, so that the method for determining the target charging equipment is simple and quick, manual operation is not needed, and the efficiency is improved.

Since the number of charging devices of the charging station is greater, there may be some charging devices of the charging station that have a connected state that is not charged, and as an alternative embodiment, the determining, from the plurality of charging devices, the charging device that has a connected state that is not charged, as the target charging device that is physically connected to the first vehicle, may include: if only a single second charging device exists in the plurality of charging devices and the corresponding connection state is the connected uncharged state, determining that the second charging device is a target charging device which is physically connected with the first vehicle; and if the connection state corresponding to at least two second charging devices in the plurality of charging devices is the connected uncharged state, randomly selecting one unselected second charging device from the at least two second charging devices as a target charging device which is physically connected with the first vehicle.

The target charging device is an unselected second charging device selected randomly from at least two second charging devices, that is, the currently determined target charging device is not necessarily the charging device connected to the first vehicle, the vehicle-mounted terminal may verify the currently determined target charging device, specifically, after executing step 240, the vehicle-mounted terminal may determine whether the first vehicle starts charging, if the first vehicle starts charging, the randomly selected second charging device is the charging device connected to the first vehicle, and if the first vehicle does not start charging, the randomly selected second charging device is not the charging device connected to the first vehicle, the vehicle-mounted terminal may execute the step of randomly selecting an unselected second charging device from the at least two second charging devices as the target charging device physically connected to the first vehicle, that is, may reselect one second charging device to perform the charging test until the first vehicle starts charging, and if the first vehicle starts charging, the determined target charging device in the at least two charging devices is the charging device connected to the first vehicle, and if the first vehicle does not start charging, the randomly selected second charging device is not the charging device connected to the first vehicle, thereby improving the accuracy of the target charging device through the method.

Step 240, according to the charging device information of the target charging device, a charging request is initiated to the server.

After determining the target charging device, the vehicle-mounted terminal may acquire charging device information of the target charging device, where the charging device information is identification information of the target charging device, so as to identify the target charging device in the multiple charging devices, and the charging device information may include a device serial number, a device name, and the like, and is not limited thereto. The vehicle-mounted terminal can initiate a charging request to the server according to the charging equipment information of the target charging equipment, and the charging request can be used for indicating the server to control the target charging equipment to start charging. It may be appreciated that, in order to enable the target charging device to charge the first vehicle, the vehicle-mounted terminal may configure, before initiating the charging request to the server, the connection mode corresponding to the first vehicle to be the second mode, so that the connection state corresponding to the first vehicle is the connected uncharged state, and so that the connection state corresponding to the target charging device is the connected uncharged state.

In this embodiment of the present application, the vehicle-mounted terminal may configure a connection mode corresponding to the first vehicle as a target connection mode, where the connection mode is used to control a connection state corresponding to the first vehicle, and may obtain connection states corresponding to the plurality of charging devices respectively, so that the target charging device that is physically connected to the first vehicle may be determined from the plurality of charging devices according to the connection state corresponding to the first vehicle and the connection states corresponding to the plurality of charging devices respectively, data communication between the first vehicle and the charging device is not required, and other matching operations such as code scanning are not required by a user, the target charging device is determined according to the connection states of the charging devices, and finally, a charging request is initiated to the server according to charging device information of the target charging device, so as to instruct the server to control the target charging device to start charging, thereby protecting information security of vehicle charging and improving charging convenience.

As shown in fig. 3-a, fig. 3-a is a schematic flow chart of another vehicle charging method disclosed in an embodiment of the present application, where the vehicle charging method may be applied to the vehicle-mounted terminal of the first vehicle in the foregoing embodiment, and the vehicle charging method may include the following steps:

step 310, configuring a connection mode corresponding to the first vehicle as a target connection mode.

Step 320, obtaining connection states corresponding to the plurality of charging devices respectively.

The method of steps 310-320 is the same as the method of steps 210-220 in the above embodiment, and will not be repeated here.

Step 330, change the corresponding connection mode of the first vehicle and determine the current connection state change of the first vehicle.

The vehicle-mounted terminal can change the corresponding connection mode of the first vehicle, namely, the corresponding connection mode of the first vehicle can be changed from the first mode to the second mode, or the corresponding connection mode of the first vehicle can be changed from the second mode to the first mode, and as the corresponding connection mode of the first vehicle changes, the corresponding connection state of the first vehicle also changes, the vehicle-mounted terminal can determine the current connection state change of the first vehicle, and the connection state change can refer to the change process of the connection state. The current connection state change of the first vehicle may be a change from the unconnected state to the connected unconnected state when the corresponding connection mode of the first vehicle is from the first mode to the second mode, and the current connection state change of the first vehicle may be a change from the connected unconnected state to the unconnected state when the corresponding connection mode of the first vehicle is from the second mode to the first mode.

In one embodiment, the first vehicle may include a switching device, and the in-vehicle terminal may change a corresponding connection mode of the vehicle by controlling on and off of the switching device. Alternatively, the vehicle-mounted terminal may open the switching device to switch the corresponding connection mode of the first vehicle to the first mode, and determine that the current connection state of the first vehicle changes from the connected uncharged state to the unconnected state; or, the in-vehicle terminal may turn off the switching device so that the corresponding connection mode of the first vehicle is switched to the second mode, and determine that the current connection state of the first vehicle is changed from the unconnected state to the connected uncharged state.

In the case of wired connection, the switching device may include a single-pole switch, a slide switch, etc., and the switching device may be disposed on a connection circuit between the first vehicle and the charging device, so that the connection circuit between the first vehicle and the charging device may be disconnected when the switching device is opened, and the connection circuit between the first vehicle and the charging device may be routed when the switching device is closed. Optionally, the switch device may be disposed in a charging socket of the first vehicle, specifically, the charging gun of the charging device includes a CC port, the switch device may be disposed at a contact corresponding to the CC port in the charging socket of the first vehicle, if the charging socket is not provided with the switch device, when the charging gun of the charging device is plugged into the charging socket of the first vehicle, the charging device may be directly connected with the first vehicle through the CC port, in this embodiment, the CC port is provided with the switch device, even if the charging gun of the charging device is plugged into the charging socket of the first vehicle, the vehicle-mounted terminal may control whether the charging device may be connected with the first vehicle through the CC port by controlling the switch device.

According to the embodiment, the switch device is arranged to configure the corresponding connection mode of the first vehicle so as to further control the connection of the first vehicle and the charging equipment, so that the change of the connection state can be controlled to determine the target charging pile, the autonomous control of the first vehicle on charging is improved, and the accuracy of the determined target charging pile is improved.

Step 340, obtaining connection states corresponding to the plurality of charging devices respectively again.

The vehicle-mounted terminal can acquire the connection states corresponding to the plurality of charging devices again, and the connection states are not repeated.

And 350, determining the connection state change corresponding to the plurality of charging devices according to the connection states corresponding to the plurality of charging devices acquired in the last two times.

The vehicle-mounted terminal compares connection states respectively corresponding to the plurality of charging devices acquired last twice, taking the first charging device as an example, the first charging device can be any charging device in the plurality of charging devices, if the connection states acquired last twice by the first charging device are different, it can be determined that the connection state corresponding to the first charging device changes from the connection state acquired last second time to the connection state acquired last first time, for example, the connection state corresponding to the first charging device changes from an unconnected state to an unconnected state, and if the connection states acquired last twice by the first charging device are the same, it can be determined that the connection state corresponding to the first charging device changes to a state unchanged.

Step 360 determines, from the plurality of charging devices, a charging device whose corresponding connection state change matches the current connection state change of the first vehicle as a target charging device physically connected to the first vehicle.

Because the connection state corresponding to the first vehicle is the same as the connection state corresponding to the connected charging device, the current connection state change of the first vehicle may also be the same as the connection state change corresponding to the connected charging device, and then taking the first charging device as an example, the vehicle-mounted terminal may determine whether the connection state change corresponding to the first charging device is matched with the current connection state change of the first vehicle, that is, determine whether the connection state change corresponding to the first charging device is the same as the current connection state change of the first vehicle, and after completing the determination of all the charging devices, the vehicle-mounted terminal may determine a target charging device corresponding to the connection state change matched with the current connection state change of the first vehicle from a plurality of charging devices.

In one embodiment, if only a single first charging device of the plurality of charging devices has a connection state change that matches the current connection state change of the first vehicle, determining that the first charging device is a target charging device that is physically connected to the first vehicle; and if the connection state changes corresponding to at least two first charging devices in the plurality of charging devices are matched with the current connection state changes of the first vehicle, the steps of changing the connection mode corresponding to the first vehicle and determining the current connection state changes of the first vehicle are executed again until the only target charging device which is physically connected with the first vehicle is determined from the plurality of charging devices.

Since there are multiple charging devices in the charging station, a scenario in which multiple vehicles and multiple charging devices are simultaneously matched may occur, at this time, there may be at least two connection state changes corresponding to the first charging devices in the multiple charging devices that match the current connection state change of the first vehicle, in order to ensure accuracy of the matching, the vehicle-mounted terminal may execute step 330 again, and sequentially execute step 340 to current step 360, where the current connection state change of the first vehicle is updated, and the connection states corresponding to the multiple charging devices acquired last two times are also updated, that is, the connection state changes corresponding to the multiple charging devices are updated, and repeatedly execute steps 330 to 360 described above, so as to ensure that only the connection state change corresponding to the single first charging device in the multiple charging devices matches the current connection state change of the first vehicle, thereby determining the first charging device as the target charging device physically connected with the first vehicle, and improving accuracy of the target charging device.

As an optional implementation manner, if there are at least two first charging devices in the plurality of charging devices, the connection state change corresponding to the first charging device matches the current connection state change of the first vehicle, the vehicle-mounted terminal may execute the step of changing the connection mode corresponding to the first vehicle again after waiting for the target duration, and determining the current connection state change of the first vehicle. In order to avoid that a plurality of vehicles re-execute step 330 at the same time and fall into a dead loop, each vehicle may wait for a different duration before executing step 330, i.e. the first vehicle may randomly generate the target duration within a preset duration range. By implementing the embodiment, the matching efficiency of the vehicle and the charging equipment is improved.

And step 370, initiating a charging request to the server according to the charging device information of the target charging device.

The method of step 370 is the same as that of step 240 in the above embodiment, and will not be repeated here.

In this embodiment of the present application, after obtaining connection states corresponding to a plurality of charging devices respectively, the vehicle-mounted terminal may further change a connection mode corresponding to the first vehicle and determine a current connection state change of the first vehicle, and the vehicle-mounted terminal may obtain connection states corresponding to the plurality of charging devices respectively again, and determine connection state changes corresponding to the plurality of charging devices respectively according to the connection states corresponding to the plurality of charging devices obtained in the last two times, so that a charging device, in which the connection state change matches the current connection state change of the first vehicle, may be determined from the plurality of charging devices, as a target charging device physically connected to the first vehicle, and compared with the connection state corresponding to the charging device and the connection state corresponding to the first vehicle, where accuracy of the determined target charging device can be further improved by comparing the connection state changes.

In order to more clearly express the relationship between the first vehicle, the server and the charging devices, as shown in fig. 3-B, fig. 3-B is a timing chart of a vehicle charging method disclosed in this embodiment, where the vehicle-mounted terminal may configure a connection mode corresponding to the first vehicle as a target connection mode, and may send query request information to the server, the server may obtain a connection state corresponding to each charging device according to the query request information, each charging device may return a corresponding connection state, the server receives a connection state corresponding to a plurality of charging devices, and feeds back a connection state corresponding to each of the plurality of charging devices, and if the vehicle-mounted terminal may obtain a connection state corresponding to each of the plurality of charging devices, the vehicle-mounted terminal may change a connection mode corresponding to the first vehicle again, determine a current connection state change of the first vehicle, and may obtain a connection state corresponding to each of the plurality of charging devices again by the same method, and determine a connection state change corresponding to each of the plurality of charging devices according to the last two obtained connection states respectively, the vehicle-mounted terminal may determine a connection state change corresponding to the charging devices from the plurality of charging devices, and initiate a connection state change to the charging devices as a target charging device, and may initiate a physical connection request to the first vehicle-mounted device as a charging device.

Optionally, the server may include a vehicle server corresponding to the first vehicle and charging servers corresponding to the plurality of charging devices, where the first vehicle, the vehicle server, the charging servers, and the charging devices may cooperate with each other to complete charging of the vehicle, as shown in fig. 3-C, where fig. 3-C is a timing chart of another vehicle charging method disclosed in the embodiment of the present application, the vehicle terminal may determine a charging station where the first vehicle is currently located, the vehicle terminal may configure a connection mode corresponding to the first vehicle to be a target connection mode, and may send query request information to the vehicle server, the vehicle server may forward the query request information to the charging servers, and then the charging servers may query connection states corresponding to the plurality of charging devices according to the query request information, and the charging servers may feed back connection states corresponding to the plurality of charging devices to the vehicle server, and the vehicle server may feed back connection states corresponding to the respective plurality of charging devices to the vehicle terminal of the first vehicle.

As shown in fig. 4-a, fig. 4-a is a flowchart of a method for obtaining connection states corresponding to a plurality of charging devices respectively disclosed in an embodiment of the present application, where the method for obtaining connection states corresponding to a plurality of charging devices respectively may be applied to the vehicle-mounted terminal of the first vehicle in the foregoing embodiment, and the method for obtaining connection states corresponding to a plurality of charging devices respectively may include the following steps:

step 410 establishes a communication connection with other vehicles of the first vehicle at the same charging station.

The first vehicle can inquire other vehicles with signal strength larger than the strength threshold, and can consider that the other vehicles with signal strength larger than the strength threshold are at the same charging station as the first vehicle, so as to avoid disorder of the process of matching the charging equipment among a plurality of vehicles at the same time, the first vehicle can establish communication connection with the other vehicles, and the matching process of each vehicle is ensured not to be parallel but to be serial.

In step 420, a query operation is performed to determine whether there is a vehicle that has sent query request information to the server and has not started charging among other vehicles.

The first vehicle may perform a query operation to exchange information with other vehicles, determining whether there is a vehicle that has sent query request information to the server and has not started charging among the other vehicles.

In one embodiment, when the first vehicle performs the inquiry operation, if there is a second vehicle that performs the inquiry operation simultaneously among the other vehicles, a priority order corresponding to the first vehicle and the second vehicle, respectively, is determined. Wherein the first vehicle and the second vehicle simultaneously performing the inquiry operation may refer to the second vehicle sending inquiry information to the first vehicle at the same time as the first vehicle sending inquiry information to the second vehicle. Alternatively, the priority orders corresponding to the first vehicle and the second vehicle may be preset according to the model of the vehicle, or may be generated in real time, which is not limited. In one embodiment, the first vehicle may generate a random number and the second vehicle may also generate a random number, and the first vehicle may determine a priority order of the vehicle and the first vehicle based on the random number of the first vehicle and the random number of the second vehicle. The priority order of the vehicles with larger random numbers can be determined to be higher, the priority order of the vehicles with smaller random numbers can be determined to be higher, and the priority order of the vehicles with larger factors of the random numbers can be determined to be higher. Without limitation, the embodiment is implemented such that the priority order of the first vehicle and the second vehicle can be determined by generating the random number, thereby ensuring that the first vehicle and the second vehicle concurrently acquire the connection states respectively corresponding to the plurality of charging devices.

If there is no vehicle that has transmitted the inquiry request information and has not started charging, the inquiry request information is transmitted to the server in step 430.

If there is a vehicle that has transmitted the inquiry request information and has not started charging, the first vehicle may enter a state of waiting until the inquiry request information is transmitted. Optionally, when there is no vehicle that has sent the query request information and has not started charging, the vehicle-mounted terminal may further determine whether there is a second vehicle with a priority order higher than that of the first vehicle, and if there is no second vehicle with a priority order higher than that of the first vehicle, may send the query request information to the server.

In one embodiment, after the vehicle-mounted terminal sends the query request information to the server, the server may determine whether the vehicle to be queried exists according to the sending time of the query request information sent by the first vehicle, acquire connection states respectively corresponding to the plurality of charging devices when determining that the vehicle to be queried does not exist, and wait for the vehicle to be queried to start charging when determining that the vehicle to be queried exists, and acquire connection states respectively corresponding to the plurality of charging devices.

The vehicle to be queried refers to a vehicle which sends query request information earlier than the first vehicle and does not start charging. That is, when the server receives the query request information sent by the plurality of vehicles, in order to avoid collision caused by parallel matching of the plurality of vehicles, the server may control each vehicle to perform serial matching, compare the query request information of each vehicle according to the sending time, and if the vehicle with the earlier sending time can first obtain the connection states corresponding to the plurality of charging devices fed back by the server, and if the vehicle with the later sending time can other vehicles to be queried start charging, the server will then feed back the connection states corresponding to the plurality of charging devices according to the query request of the vehicle with the later sending time.

As an optional implementation manner, the server may include a vehicle server corresponding to the vehicle and a server corresponding to the charging device, the vehicle-mounted terminal may send query request information to the vehicle server, and the vehicle server may send the query request information to the server when determining that the vehicle to be queried does not exist in the second vehicle according to the sending time of the query request information sent by the first vehicle, so that the server feeds back connection states corresponding to the plurality of charging devices respectively.

Taking the case that the vehicle-mounted terminals of three first vehicles send query request information to the server as shown in fig. 4-B, fig. 4-B is a timing chart of a method for sending query request information disclosed in the embodiment of the present application, the vehicle-mounted terminals of the first vehicles a, B and C may send query request information to the server in sequence, when the server receives the query request information of the vehicle-mounted terminals of the first vehicles a, it determines that there is no vehicle to be queried, when the server receives the query request information of the vehicle-mounted terminals of the first vehicles B, it determines that the first vehicles a are vehicles to be queried, then the server may wait for the first vehicles a to start charging and then acquire connection states respectively corresponding to the plurality of charging devices, when the server receives the query request information of the vehicle-mounted terminals of the first vehicles C, it determines that the first vehicles a and B are vehicles to be queried, then the server may wait for the first vehicles a and the first vehicles B to start charging and then acquire connection states respectively corresponding to the plurality of charging devices,

The server may acquire connection states corresponding to the plurality of charging devices respectively, and feed back the connection states corresponding to the plurality of charging devices respectively to the vehicle-mounted terminal of the first vehicle a, the vehicle-mounted terminal of the first vehicle a may determine the target charging device corresponding to the first vehicle a through a matching process, and the matching process may refer to other embodiments, which will not be described in detail herein, after the target charging device physically connected to the first vehicle a is determined through the matching process, the vehicle-mounted terminal of the first vehicle a initiates a charging request to the server, the server controls the target charging device corresponding to the first vehicle a to start charging the first vehicle a, that is, the first vehicle a starts charging, the server may then process the query request information of the first vehicle B, after similar processing, the first vehicle B starts charging, the server may finally process the query request information of the first vehicle C, and after similar processing, the first vehicle C starts charging.

Step 440, receiving connection states corresponding to the plurality of charging devices fed back by the server.

In this embodiment of the present invention, the vehicle-mounted terminal may establish a communication connection with another vehicle of the same charging station as the first vehicle, and perform a query operation to determine whether there is a vehicle that has sent query request information and has not started to charge, where when the first vehicle performs the query operation, if there is a third vehicle of the other vehicle that has simultaneously performed the query operation, the vehicle-mounted terminal determines a priority order corresponding to each of the first vehicle and the third vehicle, and if there is no vehicle that has sent query request information and has not started to charge, and there is no third vehicle of a priority order higher than that of the first vehicle, the vehicle-mounted terminal may send query request information to the server, and the first vehicle performs local communication with the other vehicle, so that a problem that the server is connected through a network is avoided to process, where a plurality of vehicles need to obtain connection states corresponding to each of a plurality of charging devices simultaneously is avoided.
