Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. 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, embodiments of the present description provide a charging system 10. As shown in fig. 1, the charging system 10 includes a vehicle end 100 (electric vehicle), a charging pile 200, and a pile cloud server 300. The pile cloud server 300 is a server for providing a charging control service for the charging pile 200.
Specifically, as shown in fig. 1, the vehicle end 100 includes a vehicle controller 110 and a charging gun rest 120. The end-of-vehicle charging gun holder 120 is provided with an identification code, which may be a bar code or a two-dimensional code, for example. The identification code carries vehicle end identification information, that is, identification information for uniquely identifying the vehicle end. 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. Of course, the vehicle end includes other components besides the vehicle controller 110 and the charging gun seat 120, and reference may be made to the structure of the existing 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 300 through a communication module provided in the charging pile, so that the pile cloud server 300 performs charging control on the charging pile 200. Install on the rifle 220 that charges and sweep a yard unit, should sweep a yard unit and be connected with charging pile controller 210. Of course, the charging pile includes other components besides the charging pile controller and the charging gun, and reference may be made to the construction of the existing charging pile, which is not described in detail herein.
It should be noted that, the position of the identification code on the charging gun base 120 corresponds to the position of the code scanning unit on the charging gun 220, and specifically, the position may be set according to the specific structure of the vehicle-end charging gun base and the charging gun, and when a user needs to use the charging gun 220 to charge a vehicle, the code scanning unit on the charging gun 220 may scan the identification code set on the vehicle-end charging gun base 120.
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 121, a gun rest body 122, and a protective cover for protecting the charging interface. The charging interface 121 is used for inserting a charging plug to charge a vehicle, and the gun base body 122 is used for bearing the charging interface and fixing the charging gun base on the electric automobile. At this time, as an implementation manner, the code scanning unit may be disposed on the outer wall of the gun body, protruding from the gun body, and the lens is oriented in the same direction as the extending direction of the charging plug, and accordingly, the identification code 123 is disposed on the gun base body. When the charging gun 220 is used for charging a vehicle, the code scanning unit on the charging gun 220 can scan the identification code 123 on the vehicle-end charging gun base 120.
As another embodiment, the code scanning unit may be disposed on a sidewall of the gun body of the charging gun 220, and the identification code may be disposed on an inner sidewall of a protective cover of the vehicle-end charging gun base 120, when the charging gun 220 needs to be inserted into the charging gun base 120, the protective cover is in an open state, and a lens of the code scanning unit faces the inner side of the protective cover, so that the identification code disposed on the inner sidewall of the protective cover can be scanned.
It should be noted that, in the embodiments of the present specification, the type of the charging interface of the electric vehicle is not limited, and the charging interface may be a direct-current charging interface, an alternating-current charging interface, or a direct-current charging interface and an alternating-current charging interface are provided at the same time. For the electric automobile who has direct current interface and the interface that charges of interchange simultaneously, can all set up above-mentioned identification code near direct current interface and the interface that charges of interchange, perhaps, also can set up above-mentioned identification code near direct current interface and the interface that charges of interchange that charges for no matter use direct current interface to charge, still use the interface that charges of interchange to charge, the code scanning unit on the rifle that charges all can scan the identification code that sets up on the rifle seat that charges, thereby realizes the control to the charging process.
Specifically, the identification code may be provided on the end-of-vehicle charging gun rest 120 in various ways, such as 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 vehicle-end identification information and pasted on the vehicle-end charging gun base. 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 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 seat.
As an optional implementation manner, a display screen may be disposed at a corresponding position of the vehicle-end charging gun seat 120, and is configured to display an identification code carrying the vehicle-end identification information. Therefore, the phenomenon that the vehicle pile communication is influenced due to the fact that the identification code is dirty or damaged can be effectively avoided, and normal charging cannot be achieved.
In the embodiments of the present specification, there may be a plurality of ways of generating the identification code, and the following two ways are mainly described below, and in the specific implementation process, other ways of generating the identification code may also be adopted, which is not limited herein.
First, the identification code may be a static identification code previously stored in the electric vehicle. For example, when the electric vehicle initializes the charging service, an identification code generation request may be sent to a vehicle cloud server for providing a service for the electric vehicle, where the identification code generation request may include vehicle-end identification information of the electric vehicle, and the vehicle cloud server encrypts the vehicle-end identification information by using a pre-stored encryption algorithm, converts the encrypted vehicle-end identification information into an identification code, and sends the identification code to the electric vehicle 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. The information that sweeps in the rifle after the sign indicating number unit scans the identification code like this is the car end identification information after encrypting, can avoid electric automobile's identity 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 a charging gun is inserted into a charging gun seat, an electric vehicle may send an identification code generation request to a vehicle cloud server, where the identification code generation request may include vehicle-end identification information of the electric vehicle; the vehicle cloud server generates a disposable identification code according to the vehicle end identification information, and issues the disposable identification code to the display screen of the electric vehicle on the charging gun base 120 for displaying.
For example, the vehicle cloud server may randomly generate an identification code for the received identification code generation request, issue the identification code to the vehicle end, display the identification code on the display, and store the identification code and the vehicle end identification information in the generation request in a preset identification code information base in a corresponding manner. After a code scanning unit on the charging gun scans to obtain an identification code and reports to a pile cloud server for providing service for a charging pile through a charging pile controller, the pile cloud server sends the identification code to a vehicle cloud server, and the vehicle cloud server can search corresponding vehicle end identification information in an identification code information base according to the identification code and determine whether the vehicle to be charged corresponds to the vehicle to be charged. After the search is completed, the identification code and the vehicle end identification information are deleted from the identification code information base, so that the vehicle cloud server cannot obtain the vehicle end identification information according to the code value after receiving the code value again, and the safety of user information is further improved.
For another example, the vehicle cloud server 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 vehicle-side identification information in the identification code generation request, and convert the fusion result into the identification code. Therefore, the identification codes generated each time are different, and after the scanning result of the identification codes is obtained, the scanning result needs to be analyzed according to the fusion mode, so that the vehicle end identification information 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.
The identification code generation mode can effectively protect the vehicle end identification information of the electric vehicle from being leaked, and the condition that the interests of the vehicle owner are damaged due to the fact that the vehicle end identification information is falsely used by other people is avoided, so that the safety of the charging process is improved. Of course, in addition to the above-mentioned several modes, in other embodiments of the present description, the vehicle-end identification information may be directly converted into an identification code for display.
In this embodiment of the present description, the charging pile 200 may be configured to scan an identification code on the vehicle-end charging gun base 120 through the code scanning unit, obtain vehicle-end identification information, and send charging request information to the pile cloud server 300. It is understood that the identification process of the identification code corresponds to the generation principle of the identification code and is not described in detail here. Specifically, the charging request information includes vehicle-side identification information and charging pile unique identification information. Wherein, fill electric pile unique identification information and can be for the only identification code who distributes in advance to fill electric pile 200 or rifle 220 that charges for the identity that the stake 200 or the rifle 220 that charges is filled in the sign. For example, the charging pile unique identification information may be stored in the memory of the charging pile 200 in advance, and acquired from the memory when a charging request needs to be generated.
In an alternative embodiment, the charging post 200 may trigger the code scanning unit to scan the identification code on the end-of-vehicle charging gun holder 120 when the charging gun 220 is detected to be inserted into the end-of-vehicle charging gun holder 120. Therefore, the code scanning unit can start to work when code scanning is required, resources are saved, and the service life of the code scanning unit is prolonged. For example, the charging post 200 may detect the connection status by detecting the voltage and/or current of the charging plug on the charging gun 220. 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 plug may be changed, and thus, by detecting the voltage and/or current at the charging plug, it is possible to detect whether the charging gun 220 is inserted into the charging gun holder 120.
In an alternative embodiment, the identification code is displayed by a display screen provided on the vehicle-end charging gun mount 120, and the vehicle controller may trigger the display screen to display the graphic code upon detecting that the charging gun 220 is inserted into the vehicle-end charging gun mount 120. Furthermore, the display brightness of the display screen can be adjusted according to the ambient brightness.
Further, after receiving the charging request information reported by the charging pile 200, the pile cloud server 300 may verify the charging request information, and determine whether to control the charging pile to charge the vehicle end according to a verification result.
Specifically, the pile cloud server 300 may first verify the vehicle-side identification information in the charging request information, and if the vehicle-side identification information passes the verification, control the corresponding charging pile 200 to start charging according to the unique charging pile identification information. If the verification fails, the charging control process 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 for the non-verification may be sent to the mobile phone of the corresponding owner, or may be displayed on the electronic screen of the charging pile 200.
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 obtain the charging authority of the charging pile 200 conveniently, 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: judging whether the vehicle-side identification information is bound with a charging account and whether the charging account meets a preset charging condition, if so, indicating that the electric vehicle has charging authority; if the charging account is not bound or the bound charging account does not meet the preset charging condition, it indicates that the electric vehicle does not have the charging authority. 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 may be registered through a client corresponding to the stub cloud server 300 for payment of charging fees.
