Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
In a first aspect, the present specification provides a charging control system. As shown in fig. 1, the charge control system 10 includes a vehicle end 100, a charging pile 200, and a server.
Specifically, the charging gun is connected to the charging pile 200, and the code scanning unit is installed on the charging gun seat of the vehicle end 100 and used for scanning the identification code on the charging gun and acquiring the unique identification information of the charging pile. The identification code carries unique identification information of the charging pile, and is used for uniquely identifying the charging gun or the identity of the charging pile where the charging gun is located. Further, the vehicle end 100 may initiate the charging request information to the server. The charging request information comprises vehicle end identification information and charging pile unique identification information. The vehicle-end identification information is used as an identification of the vehicle end, and may be, for example, a VIN of the vehicle, or may be other information capable of uniquely identifying the vehicle identity, such as a serial number assigned to the vehicle specifically for the charging service.
The server is used for verifying the charging request information sent by the vehicle end and determining whether to control the charging pile to charge the vehicle end according to a verification result.
In this illustrative embodiment, the servers may include a car cloud server 310 and a stub cloud server 320, as described in fig. 1. The car cloud server 310 is in communication connection with the vehicle end 100 to provide services for the vehicle end, and the pile cloud server 320 is in communication connection with the charging pile 200 to provide services for the charging pile, such as charging control services. The car cloud server 310 and the pile cloud server 320 may be integrally arranged or may be arranged independently of each other, which is determined according to an actual application scenario. For convenience of explanation, in the following embodiments of the present specification, the servers are described as being divided into the car cloud server 310 and the stub cloud server 320.
As shown in fig. 1, the vehicle end 100 includes a vehicle controller 110 and a charging gun rest 120, and the vehicle controller 110 is communicatively connected to a vehicle cloud server 310. The charging gun base 120 is provided with a code scanning unit, and the code scanning unit is connected with the vehicle controller 110. Of course, the vehicle end 100 includes other components besides the vehicle controller 110 and the charging gun rest 120, and refer to the structure of the existing electric vehicle, which will not be described in detail herein.
The charging post 200 includes a charging post controller 210 and a charging gun 220. The charging pile controller 210 may be in communication connection with the pile cloud server 320 through a communication module provided in the charging pile 200, so that the pile cloud server 320 performs charging control on the charging pile 200. The charging gun 220 is provided with an identification code, which may be a bar code or a two-dimensional code, for example. The identification code carries unique identification information of the charging pile. Of course, the charging post 200 includes other components besides the charging post controller 210 and the charging gun 220, and reference may be made to the construction of the existing charging post, which will not be described in detail herein.
In the embodiment of the present disclosure, the installation position of the code scanning unit on the charging gun base 120 corresponds to the position of the identification code on the charging gun 220, and it is required to be convenient for a user to scan the identification code on the charging gun 220 when the user charges a vehicle by using the charging gun 220.
For example, in one application scenario, the charging gun 220 includes a gun body provided with a charging plug and a handle bent or inclined at an angle to the gun body. As shown in fig. 2, the end-of-vehicle charging gun rest 120 may include a charging interface 201 and a gun rest body 202. The charging interface 201 is used for inserting a charging gun to charge a vehicle, the gun base body 202 is used for bearing the charging interface 201, and the whole charging gun base is fixed on the electric automobile. At this time, as an embodiment, the identification code may be disposed inside the handle of the charging gun 220, and accordingly, the code scanning unit 203 may be disposed at the bottom of the gun base body 202 with the lens facing the handle of the charging gun 220, and when the charging gun 220 is used to charge a vehicle, the identification code on the charging gun 220 may be located in a scanning area of the code scanning unit 203.
As another embodiment, the identification code may be disposed on the gun body housing of the charging gun 220 near the charging plug, and accordingly, the code scanning unit 203 is disposed on the sidewall of the groove where the charging gun base 120 is located, and the lens of the code scanning unit faces the identification code, and when the charging gun 220 is used to charge a vehicle, the identification code is located in the scanning area of the code scanning unit 203.
It should be noted that, in the embodiment of the present disclosure, the type of the charging gun base of the electric vehicle is not limited, and the charging gun base 120 may be a direct-current charging interface, an alternating-current charging interface, or a direct-current charging interface and an alternating-current charging interface. For the electric automobile that has direct current interface and the interface that charges of interchange simultaneously, can be near direct current charge interface and near the interface that charges of interchange set up one above-mentioned yard unit 203 of sweeping respectively, perhaps, also can sweep yard unit 203 and set up the position department near direct current interface and the interface that charges of interchange for no matter use the interface that charges of direct current to charge, still use the interface that charges of interchange to charge, the yard unit of sweeping on the rifle seat 120 that charges all can scan the identification code that sets up on the rifle 220 that charges, thereby realize the control to the charging process.
Specifically, the identification code may be provided on the charging gun 220 in various ways, for example, by spraying or pasting. Furthermore, if the identification code is a graphic code such as a bar code or a two-dimensional code, the identification code can be scanned when the light is dark. As an embodiment, the identification code may be a fluorescent identification code, for example, a fluorescent two-dimensional code sticker may be made according to the unique identification information of the charging pile and pasted on the charging gun 220. As another embodiment, a brightness sensor and an illumination module may be disposed on the charging gun 220 or the end-of-vehicle charging gun holder 120. The brightness sensor is used for collecting the ambient brightness, and the illumination module is used for providing illumination when the ambient brightness is lower than a preset threshold value so as to illuminate the identification code on the charging gun 220.
In an optional implementation manner, a display screen may be disposed at a corresponding position of the charging gun 220, and is configured to display an identification code carrying the unique identification information of the charging pile. Therefore, the phenomenon that the communication between the vehicle piles is influenced due to the fact that the identification codes are dirty or damaged, and the charging is unsuccessful is avoided.
The identification code may be generated in a variety of ways, and the following two ways are mainly described below, and other ways may be used in the specific implementation process, which is not limited herein.
First, the identification code may be a preset static identification code. For example, when the charging pile 200 initializes the charging service, an identification code generation request may be sent to the pile cloud server 320, where the identification code generation request may include unique identification information of the charging pile; the pile cloud server 320 encrypts the unique identification information of the charging pile by adopting a pre-configured encryption algorithm, converts the encrypted unique identification information of the charging pile into an identification code, and sends the identification code to the charging pile 200 for storage. For example, the encryption algorithm may be a symmetric encryption algorithm such as AES, DES, or 3DES algorithm, or other suitable encryption algorithms. Like this charge sweep information that obtains behind the yard unit scanning identification code on the gun platform 120 for the electric pile unique identification information that fills after encrypting, can avoid filling electric pile 200 or the identity of charging rifle 220 to reveal so that there is the potential safety hazard effectively.
Second, the identification code may also be a disposable identification code generated in real time, and becomes invalid after being used once. For example, when detecting that the charging gun 220 is inserted into the charging gun base 120 of the vehicle, the charging pile terminal may send an identification code generation request to the pile cloud server 320, where the identification code generation request may include unique identification information of the charging pile; the pile cloud server 320 generates a disposable identification code according to the unique identification information of the charging pile, and issues the disposable identification code to the charging pile 200, and the disposable identification code is displayed through a display screen arranged on the charging gun 220.
For example, the pile cloud server 320 may randomly generate an identification code for the received identification code generation request, and store the identification code and the charging pile unique identification information in the identification code generation request in a preset identification code information base in a corresponding manner. Scanning at vehicle end 100 and obtaining the identification code, and reporting to car cloud server 310, car cloud server 310 sends the identification code to pile cloud server 320, and pile cloud server 320 can look for the corresponding unique identification information of charging pile in the identification code information base according to the identification code, and after finishing looking for, deletes the identification code and the unique identification information of charging pile from the identification code information base, so after receiving the identification code again, can't obtain the unique identification information of charging pile according to the identification code again.
For another example, the pile cloud server 320 may generate and record a random number for the received identification code generation request, and then perform fusion processing on the random number and the charging pile unique identification information in the identification code generation request, and convert the fusion result into the identification code. Therefore, the identification codes generated every time are different, and after the scanning result of the identification codes is obtained, the scanning result needs to be analyzed according to a fusion mode, so that the unique identification information of the charging pile carried in the scanning result can be obtained. The fusion processing may be an exclusive or operation or a reversible processing manner such as splicing, and is not limited herein.
Therefore, the charging process is easily attacked by a malicious third party due to the fact that the unique identification information of the charging pile 200 or the charging gun 220 is leaked can be effectively avoided, and the safety of the charging process is improved. Of course, in addition to the above generation manner, in other embodiments of the present description, the unique identification information of the charging pile may be directly converted into an identification code for displaying. In addition, it is understood that the identification process of the identification code corresponds to the generation principle of the identification code, and the detailed description is omitted in this embodiment.
In an alternative embodiment, the vehicle end 100 is configured to trigger the code scanning unit to scan the identification code on the charging gun 220 when the insertion of the charging gun 220 into the charging gun holder 120 is detected. Therefore, the code scanning unit 203 can start working when code scanning is required, which is beneficial to saving resources and prolonging the service life of the code scanning unit 203. And then, initiating a charging request to a server according to the scanned unique identification information of the charging pile and the pre-stored vehicle end identification information. In one embodiment, the vehicle-end identification information may be stored in a memory of the vehicle end 100 in advance, and acquired from the memory when a charging request needs to be initiated.
For example, the vehicle controller 110 may detect the connection status by detecting the voltage and/or current of the charging interface in the charging gun rest 120. It is understood that when the user inserts the charging gun 220 into the charging gun holder 120, the voltage and/or current at the charging interface may change, and thus, by detecting the voltage and/or current at the charging interface, it is possible to detect whether the charging gun is inserted into the charging gun holder 120.
In an alternative embodiment, the identification code is displayed by a display screen provided on the charging gun 220, and the charging pile 200 may trigger the display screen to display the identification code when it is detected that the charging gun 220 is inserted into the end-of-vehicle charging gun holder 120. Furthermore, the display brightness of the display screen can be adjusted according to the ambient brightness. This is advantageous in saving power resources.
Specifically, the vehicle end 100 may report the charging request information to the vehicle cloud server 310, and the vehicle cloud server 310 may first verify vehicle end identification information carried in the charging request information, and if the vehicle end identification information passes the verification, send a charging start instruction to the pile cloud server 320, where the charging start instruction carries unique identification information of the charging pile acquired from the charging request information. The pile cloud server 320 controls the corresponding charging pile 200 to start charging the vehicle according to the unique identification information of the charging pile carried in the charging start instruction. Of course, if the verification is not passed, the present charge control routine is ended. Further, a notification message can be sent to the corresponding vehicle owner to inform the vehicle owner of the verification result and the reason of the non-verification. For example, the verification result and the reason of the non-verification may be sent to a mobile phone of the corresponding owner, or may be displayed on an electronic screen of the charging pile.
Considering that the failure of the verification may be because the owner is not a registered user of the management platform corresponding to the charging pile 200, as an alternative embodiment, when the verification fails, an indication message and/or a coupon may be sent to the owner, where the indication message is used to guide the user to register. Thus, the user can conveniently register the charging authority of the charging pile, and the user is helped to use the charging pile 200 to charge the vehicle.
In a specific implementation process, the verification modes may be various, and are specifically set according to the needs of an actual application scenario. For example, it may be verified whether the electric vehicle corresponding to the vehicle-side identification information has the charging authority, and/or whether the vehicle-side identification information is valid.
In one embodiment, the process of verifying whether the electric vehicle has the charging right may include: whether a charging account is bound to the vehicle-end identification information or not and whether the charging account meets a preset charging condition or not can be judged, if yes, the electric vehicle is indicated to have charging authority, and the electric vehicle is judged to pass the verification; if the charging account is not bound or the bound charging account does not meet the preset charging condition, the electric automobile does not have the charging authority, and the verification is judged not to pass. The preset charging condition may be specifically set according to an actual application scenario, for example, the balance of the charging account exceeds a preset threshold, the charging account has no arrears, or the charging account is not added to a preset blacklist, and the like.
The charging account can be registered through the client and used for paying charging fee. In this embodiment, the client may be a client corresponding to the stub cloud server 320, or may also be a client corresponding to the car cloud server 310, which is not limited herein. At this time, as shown in fig. 1, the charging control system may further include a user terminal 400, and the client, such as a browser or a third-party application, is installed in the user terminal 400. The client is used for responding to an account creating instruction triggered by a user, creating a charging account for the user, responding to a binding instruction triggered by the user, binding the vehicle end identification information input by the user with the created charging account, and storing the binding relationship between the vehicle end identification information and the charging account in the pile cloud server 320. Of course, after the binding relationship is established, the user can also unbind the client at any time according to the requirement. In addition, before the user charges the electric automobile, the user can recharge the charging account through the client so as to pay the charging cost.
In one embodiment, the verifying whether the vehicle-end identification information is valid may include: the car cloud server 310 parses the car-end identification information from the received charging request, and then verifies whether the car-end identification information is valid. For example, if the vehicle-end identification information is the VIN of the vehicle, it is verified whether the VIN is valid, for example, whether the vehicle passes annual inspection, and the like.
After the vehicle-side identification information is verified, the server can issue a starting instruction to the corresponding charging pile 200 according to the unique charging pile identification information carried in the received charging request information. After receiving the start instruction, the corresponding charging pile controller 210 controls the charging pile 200 to start charging the electric vehicle. Therefore, the user only needs to insert the charging gun 220 into the charging gun seat 120 to charge the electric automobile, the charging gun is not limited to a direct current or alternating current charging mode, extra vehicle pile communication operation is not needed, plug-and-play charging is facilitated, the charging process is simplified, and the user experience is improved.

In particular, the risk detection step may comprise: acquiring charging characteristic data of an electric vehicle to be charged; inputting the charging characteristic data into a pre-trained risk detection model, determining whether the charging behavior of the electric automobile is abnormal or not according to the output risk detection result, if so, sending a charging confirmation notice to an owner of the electric automobile, controlling the charging pile to charge the electric automobile after the owner replies the confirmation information, and if not, executing the step of controlling the charging pile to charge the electric automobile without confirming to the owner.
For example, the charging characteristic data may include: charging behavior information and user profile information. The charging behavior information is used for reflecting the current charging behavior and the historical charging behavior of the electric vehicle, and may include, but is not limited to, a current charging area, a current charging time period, an interval time from last charging, historical charging area statistical information, historical charging frequency statistical information, historical charging time period statistical information, and the like. The user profile information may include the owner's age, gender, occupation, work area, residence area, etc. For example, the historical charging frequency statistics may include, but are not limited to, an average of historical charging interval times, a number of charges in a recent year, and the like.
The risk detection model can be trained by acquiring a plurality of sample data based on the existing applicable machine learning model such as a neural network model and a support vector machine as an initial model, wherein each sample data comprises: the charging characteristic data of the sample electric automobile and the label used for representing whether the charging behavior of the sample electric automobile is abnormal or not. The risk detection result output by the model can be a risk score, the value range of the output risk score can be 0-1, or can be 0-100, if the output risk score exceeds a preset threshold value, the charging behavior of the electric automobile is judged to be abnormal, and if the output risk score does not exceed the preset threshold value, the charging behavior of the electric automobile is judged to be not abnormal. The preset threshold may be set according to multiple tests, for example, if the value range of the risk score is 0-100, the preset threshold may be set to 40, 50, or 60, etc.
Through the risk detection steps, the abnormal charging behavior caused by malicious operations such as stealing of vehicle end identification information of other vehicles can be effectively detected, the safety of the charging process is further guaranteed, and the benefit of a user is guaranteed.
Further, after charging is finished, the charging fee also needs to be paid through a charging account pre-bound at the vehicle end. Specifically, the stub cloud server 320 is further configured to: if the charging of the vehicle by the charging pile 200 is finished, deduction is carried out from a charging account pre-bound with the vehicle according to the current charging data of the vehicle so as to pay the charging fee. It is understood that the charging data of the vehicle may be obtained from the charging pile 200 or the electric vehicle in real time, for example, the charging data may include the charging time, the charging amount, and the like. The charge of the current charging can be calculated according to the charging time and the charging electric quantity.
In this embodiment, after the charging is completed, that is, the electric vehicle is fully charged, the charging pile 200 may automatically complete the charging of the vehicle. Or, the user may trigger a charging stop instruction through a client installed on the user terminal 400, the client sends a charging end request to the pile cloud server 320 in response to the charging stop instruction triggered by the user, and the pile cloud server 320 sends a charging pile closing instruction to the charging pile 200 based on the charging end request to control the charging pile 200 to stop charging the vehicle. In an embodiment, the charging end request may include vehicle end identification information of the electric vehicle bound by the user, the pile cloud server 320 stores a charging state list, the charging state list stores a corresponding relationship between the charging pile 200 or the charging gun 220 in the charging state and the electric vehicle to be charged, and the pile cloud server 320 may search the charging pile 200 or the charging gun 220 for charging the electric vehicle in the charging state list according to the vehicle end identification information in the charging end request, and may further send a charging pile closing instruction to the corresponding charging pile 200 to control the charging pile 200 to stop charging the electric vehicle.
In addition, after the charging of the electric vehicle is finished, the charging pile 200 may send a charging end notification to the pile cloud server 320, and the pile cloud server 320 may determine that the charging of the vehicle is finished when receiving the charging end notification, and may execute the charging fee payment process.
Optionally, after the charging fee payment is completed, the pile cloud server 320 may notify the user of detailed information of the charging order, such as the charging amount and the charging fee, by using application push and/or a mobile phone short message. In an embodiment, if the pile cloud server fails to deduct money due to reasons such as insufficient balance of the charging account, the pile cloud server 320 may prompt the user to recharge the charging account before the user charges next time, so as to complete the payment of the charging fee, otherwise, the new charging cannot be started.
In addition, in an optional embodiment, in order to ensure the security of data transmission in the charging control system, and avoid a charging process error caused by malicious tampering of the vehicle-end identification information and/or the unique identification information of the charging pile in the transmission process, when the vehicle end 100 generates a charging request, the vehicle-end identification information and the unique identification information of the charging pile to be carried in the charging request may be encrypted, and then the encrypted data is encapsulated, so as to generate the charging request and report the charging request to the vehicle cloud server 310.
Correspondingly, after the vehicle cloud server 310 obtains the charging request, the charging request is analyzed to obtain encrypted data, and the encrypted data is decrypted through a pre-stored decryption algorithm to obtain vehicle end identification information and charging pile unique identification information. For example, the encryption algorithm may be an asymmetric encryption algorithm, such as an RSA algorithm or an Elliptic Curve Cryptography (ECC), and each electric vehicle may generate a unique public key and private key pair in advance, and provide the public key thereof to the vehicle cloud server 310 for storage in the public key information base. Thus, the vehicle end 100 can encrypt the vehicle end identification information to be carried and the charging pile unique identification information through the private key, and the vehicle cloud server 310 can decrypt the encrypted data through the pre-stored public key of the corresponding electric vehicle to obtain the vehicle end identification information and the charging pile unique identification information carried in the charging request. In addition, since the public keys of different electric vehicles are different, after the vehicle cloud server 310 stores the public key of the electric vehicle, the index information of the public key may be fed back to the electric vehicle, and the charging request generated by the vehicle end 100 may carry the index information, so that the vehicle cloud server 310 searches for and obtains the public key for decryption from the public key information base through the index information.
Of course, besides the asymmetric encryption algorithm, other applicable encryption algorithms may be used in the encryption transmission process, and the encryption transmission process is not limited herein.
