Referring to fig. 1, fig. 1 is a diagram of an implementation environment of an embodiment of the present application. In this embodiment, the technical solution of the present application may be implemented on the background server 20, as shown in fig. 1, the background server 20 obtains the first electric quantity of the target electric vehicle 10, and controls the camera to photograph license plate information of the target electric vehicle 10 and receives the license plate information, according to the license plate information, user information, vehicle model, battery parameters and the like corresponding to the license plate information are inquired and determined, to determine the charging power of the target electric vehicle 10 based on the battery parameters and the first amount of charge, and to determine the charging strategy of the target electric vehicle 10 in combination with the previously acquired power parameters of the charging device 30 in the charging field and the second amount of charge of the other electric vehicle 40, to allocate the target charging apparatus 300 for the target electric vehicle 10 from the charging apparatus 30 based on the charging strategy, and transmits control information to the target electric vehicle 10 to cause the target electric vehicle 10 to automatically drive to the charging potential of the target charging apparatus 300; the backend server 20 then transmits a control instruction to the target charging apparatus 300 to cause the target charging apparatus 300 to execute the control instruction, perform operations such as charging on the target electric vehicle 10.

Here, the target electric vehicle herein refers to an electric vehicle to be charged, and the other electric vehicles refer to electric vehicles being charged in a charging field. The background server 20 is a system capable of receiving and processing a signal and controlling a corresponding device to perform an operation, and may be an independent physical server or terminal, a server cluster formed by a plurality of physical servers, or a cloud server providing basic cloud computing services such as a cloud server, a cloud database, a cloud storage, and a CDN.

Referring to fig. 2, the present application provides a charging control method for an electric vehicle, so as to reasonably utilize a charging device of a charging field, thereby solving the problem of low effective utilization rate of the existing charging device. In one embodiment, the method for controlling charging of an electric vehicle includes:

and S21, acquiring a first electric quantity of the target electric vehicle and a battery parameter thereof, and determining charging power according to the battery parameter and the first electric quantity.

In real life, the same electric vehicle can use charging equipment with multiple charging powers, and different charging powers may affect the charging effect of the electric vehicle, such as charging time, battery heating condition or battery service life. Therefore, in this step, when the user initiates a charging request through a client such as a vehicle-mounted terminal or a mobile phone, the background server responds to the charging request, obtains the first electric quantity of the target electric vehicle and the battery parameter of the battery configured in the target electric vehicle, and determines the appropriate charging power of the target electric vehicle according to the first electric quantity and the battery parameter, so that the user can save the effort of finding appropriate charging equipment through an intelligent operation process, and more convenient and efficient service is provided for the user.

Here, the first power amount refers to a remaining power amount of the current target electric vehicle. The battery parameters may include: electromotive force, rated voltage, open circuit voltage, operating voltage, end voltage, charging voltage, internal resistance, capacity, specific energy and specific power, storage performance and self-discharge, lifetime, and the like.

In this step, the charging power may be determined according to the first electric quantity or the battery parameter according to a conversion rule or a table look-up manner. Specifically, when the first charge amount of the target electric vehicle is low, the charging power of the target electric vehicle is large. For example, when the first electric quantity is 10%, the corresponding charging power can be determined to be 150KW by looking up the table; when the first electric quantity is 20%, the corresponding charging power can be determined to be 100KW through a table look-up.

After obtaining a plurality of charging powers according to the first electric quantity, the appropriate charging power can be screened out according to the battery parameter, for example, when the battery parameter represents that the charging current needs to be limited within a certain range, or the battery of the target electric vehicle is easy to heat, a smaller charging power is further selected, so that the service life of the battery of the target electric vehicle is prolonged.

And S22, acquiring the power parameters of the charging equipment in the charging field and the second electric quantity of other electric vehicles.

The method comprises the steps of obtaining power parameters of all charging devices in the charging field and second electric quantity of other electric vehicles so as to know the use condition of the charging devices in the current charging field and the charging condition of the other electric vehicles. Specifically, the background server can acquire the power parameters by inquiring nameplate information of each charging device; the other electric vehicles respond to the acquisition request and send the second electric quantity to the background server, so that the second electric quantity is acquired. Of course, other electric vehicles may also send the charging completion status to the background server in real time during the charging process, so that the background server performs corresponding operations, for example, when the charging of other electric vehicles is completed, the power-off operation of the charging device is controlled, and a charging completion message and charging fee information are sent to the user.

The power parameters may include an operating voltage, an actual power, and an operating current of the charging device. The other electric vehicle is an electric vehicle that is being charged or is completed in a charging field. The second amount of power is a current battery power of the other electric vehicle.

S23, performing priority analysis according to at least one of the charging power, the power parameter or the second electric quantity, and determining the charging strategy of the target electric vehicle.

After the background server acquires the charging power, the power parameter and the second electric quantity, priority analysis can be carried out according to at least one of the charging power, the power parameter or the second electric quantity, and a charging strategy of the target electric vehicle is determined. For example, a charging device matching the charging power may be preferentially selected according to the charging power, when there is no charging device matching the charging power among the idle charging devices, a charging device having a smaller difference from the charging power may be selected, or a current charging device of another electric vehicle may be switched to another charging device to idle a suitable charging device for the target electric vehicle.

Before switching the charging equipment of other electric vehicles, priority analysis needs to be carried out on the target electric vehicle and other electric vehicles, when the electric quantity of other electric vehicles is lower than that of the target electric vehicle, the priority of other electric vehicles is higher than that of the target electric vehicle, the charging equipment of other electric vehicles is not switched, the charging equipment with lower power is distributed for the target electric vehicle, and therefore a charging strategy is formulated for the target electric vehicle by combining the electric quantity condition and the charging field condition of the target electric vehicle, the limited charging equipment of the charging field is reasonably utilized, and the effective utilization rate of the charging equipment is improved.

In one embodiment, when the priority of other electric vehicles is changed after charging for a period of time, the charging strategy can be re-established, and the target electric vehicle is charged based on the re-established charging strategy.

In addition, the charging strategy may also include the charging time, charging fee, and corresponding charging device or switching mode between charging devices of the target electric vehicle. For example, a high-power charging device may be selected to charge the target electric vehicle first, and after charging for a period of time, the charging device switched to a lower-power charging device continues to charge the target electric vehicle until charging is completed.

And S24, distributing a target charging device for the target electric vehicle based on the charging strategy, and charging the target electric vehicle by using the target charging device.

This step allocates a target charging device to the target electric vehicle based on the formulated charging strategy, and charges the target electric vehicle using the target charging device. Specifically, the background server can obtain positioning information of the target electric vehicle and position information of the target charging device, determine an optimal driving path according to the positioning information of the target electric vehicle and the position information of the target charging device, guide the target electric vehicle to drive to a charging position of the target charging device based on the optimal driving path, control the target electric vehicle to open a corresponding charging port cover when the target electric vehicle is detected to drive to the charging position of the target charging device, send an instruction to the target charging device, insert a gun into the charging port of the target electric vehicle, and finally issue a charging instruction to the target charging pile to charge the target electric vehicle. Wherein, this battery charging outfit is including filling electric pile, charging station, trading power station etc..

According to the charging control method of the electric vehicle, the first electric quantity and the battery parameter of the target electric vehicle are obtained, and the charging power is determined according to the battery parameter and the first electric quantity, so that the charging power suitable for the current target electric vehicle is obtained; then acquiring power parameters of charging equipment in the charging field and second electric quantity of other electric vehicles; performing priority analysis according to at least one of the charging power, the power parameter or the second electric quantity to determine a charging strategy of the target electric vehicle; and finally, distributing target charging equipment for the target electric vehicle based on the charging strategy, and charging the target electric vehicle by using the target charging equipment. This application formulates suitable charge strategy for target electric vehicle through current electric quantity condition and the charging field condition based on target electric vehicle to call suitable target charging equipment to charge target electric vehicle under this charge strategy, thereby the charging equipment of rational utilization charging field improves charging equipment's utilization ratio and charge efficiency, and realizes intelligent charging.

In an embodiment, as shown in fig. 3, step S21 may specifically include:

and S211, acquiring user information of the target electric vehicle.

S212, receiving first electric quantity sent by the target electric vehicle.

S213, inquiring the battery parameter of the target electric vehicle according to the user information, and determining the charging power according to the battery parameter and the first electric quantity.

In this embodiment, when the target electric vehicle travels to the gate, a charging request is sent to the background server, and the background server obtains the user information and the first electric quantity of the target electric vehicle in response to the charging request, and queries information such as battery parameters, vehicle models, and historical charging information of the target electric vehicle from the cloud or the database according to the user information. After information such as battery parameters can be registered on corresponding APP of the mobile phone through a user, the background server stores the registration information of the user, then vehicle information such as vehicle model of the user is collected, and battery information corresponding to a target electric vehicle is inquired according to the vehicle model, so that the battery parameters are obtained and stored in a cloud or a database.

When user information of a target electric vehicle is acquired, a camera of a gate machine can be controlled by a background server to shoot license plate information of the target electric vehicle and acquire the license plate information; and then inquiring user information corresponding to the license plate information from the cloud according to the license plate information. According to the embodiment, the license plate information is automatically recognized, an automatic query process is realized, and a user does not need to send related information, so that the charging process is simplified, and the user experience is improved.

In an embodiment, before a user drives in a gate, a charging request can be initiated to a background server in advance, the background server responds to the charging request and inquires whether appropriate charging equipment exists in a charging field, if yes, an inquiry result is fed back to the user, and after the user confirms to perform charging based on the inquiry result, the user manually drives or automatically drives to a charging position of target charging equipment to perform charging. And when the background server detects that the target electric vehicle stops at the specified charging potential, the charging equipment is controlled to charge the target electric vehicle, and the charging information is sent to the user in real time.

When the fact that the proper charging equipment does not exist in the charging field is inquired, the background server feeds back charging refusal information to the user, and if sorry is displayed on the client side and the charging station is full, the user can conveniently know the charging field condition in advance and select the proper charging field, and long-time waiting caused by the fact that the proper charging equipment does not exist after the user drives to the gate is avoided.

In an embodiment, in step S211, before the obtaining the user information of the target electric vehicle, the method may further include:

The background server of the embodiment may previously establish a network connection with the target electric vehicle so as to perform information transmission with the target electric vehicle and control of the target electric vehicle. Specifically, when the target electric vehicle enters the predetermined geographic range of the charging field, for example, when the target electric vehicle is located at a gate through a camera, or when the identifier of the target electric vehicle is detected through a network connection device such as a router, a bluetooth device, or a base station of the charging field, it may be determined whether the target electric vehicle is located within the network connection allowable range of the charging field.

When the target electric vehicle enters the preset geographic range of the charging field, the background server initiates a network connection request to the target electric vehicle, the target electric vehicle receives the network connection request, and after a confirmation instruction for allowing connection is sent to the background server according to the network connection request, the target electric vehicle accesses a network account of the charging field and establishes network connection with the background server.

Certainly, when the target electric vehicle enters the preset geographic range of the charging field, if the target electric vehicle detects a network account of the charging field, whether the target electric vehicle enters the preset geographic range of the charging field is judged according to the signal strength of the network account; if so, the target electric vehicle initiates a network connection request to a background server, and the background server establishes network connection with the target electric vehicle after receiving the network connection request initiated by the target electric vehicle.

In an embodiment, in step S24, the step of charging the target electric vehicle by using the target charging device may specifically include:

(1) after the user of the target electric vehicle is detected to get off, the target electric vehicle is controlled to automatically drive to the charging position of the target charging equipment.
