Abstract
Description
Technical Field
[0001] This invention relates to electrical engineering technology, and in particular to charging control, charging request, and charging authentication methods and devices for charging piles. Background Technology
[0002] Currently, in order to meet the charging convenience needs of electric vehicle users, many charging service operators have improved the charging process, eliminating the complicated mobile application (app) QR code scanning and card swiping charging methods, and launching a plug-and-charge function based on the vehicle identification number (VIN, also known as the chassis number) as a unique identification identifier.
[0003] In existing charging control schemes based on vehicle identification numbers (VINs), when the charging gun of a charging station is plugged into an electric vehicle, the user triggers the charging station to obtain the VIN code of the electric vehicle through the control screen of the charging station and send it to the charging station cloud platform. The charging station cloud platform then performs authentication based on the VIN code. After successful authentication, the charging station begins the process of charging the electric vehicle.
[0004] In the process of developing this application, the inventors discovered that the above-mentioned solution is prone to charging billing errors. Through research and analysis, the main reasons for this problem are as follows:
[0005] The above solution is based on the existing national standard for charging piles, GB / T 27930-2015. However, the VIN field is not mandatory in this standard. This means that many vehicles either do not support VIN code upload or may have entered a fixed value arbitrarily, leading to incorrect VIN recognition by the charging pile. Furthermore, when generating charging billing orders, the charging pile cloud platform binds the order to the vehicle owner associated with the corresponding VIN received during charging authentication. Therefore, it ultimately binds the charging billing order to the wrong vehicle owner, resulting in an incorrect charging billing order binding.
[0006] Furthermore, according to the national standard GB / T 27930-2015 for charging piles, charging piles use a plaintext transmission method based on CAN communication bus to send the VIN to the charging pile cloud platform. This poses a risk that the VIN may be maliciously obtained during transmission. When other vehicle owners use a stolen VIN to start the charging process, the resulting charging billing order will be bound to the vehicle owner of the stolen VIN, leading to incorrect charging billing order binding. Summary of the Invention
[0007] In view of this, the main objective of the present invention is to provide a charging control method and device for charging piles, which can avoid the problem of incorrect binding of charging billing orders.
[0008] To achieve the above objectives, the technical solution proposed in this embodiment of the invention is as follows:
[0009] A charging control method for a charging pile includes:
[0010] The system receives a charging request sent by an electric vehicle in response to the insertion of the charging gun into a charging station; the charging request contains encrypted text of the vehicle identification number and an encryption key for the encrypted text, the encryption key being obtained by the electric vehicle from a third-party platform where it has registered the plug-and-charge function;
[0011] According to the charging request, a plug-and-charge authentication request is sent to the third-party platform through the charging pile cloud platform to trigger the third-party platform to perform corresponding authentication based on the plug-and-charge authentication request; the plug-and-charge authentication request includes the ciphertext and the encryption key;
[0012] Based on the authentication results provided by the third-party platform, charging of the electric vehicle can be initiated or refused.
[0013] This invention also proposes a charging request method, including:
[0014] When an electric vehicle detects the insertion of a charging gun into a charging station, it sends a charging request to the charging station. The charging request contains encrypted information of the vehicle identification number and an encryption key for the encrypted information. The encryption key is obtained by the electric vehicle from a third-party platform that has registered the plug-and-charge function.
[0015] This invention also proposes a charging authentication method, including:
[0016] A third-party platform generates an encryption key for electric vehicles that have registered the plug-and-charge function on this platform and sends it to the electric vehicle; the encryption key is used to encrypt the vehicle identification number of the electric vehicle during plug-and-charge authentication.
[0017] The system receives a plug-and-charge authentication request sent by the charging pile through the charging pile cloud platform, performs corresponding authentication based on the plug-and-charge authentication request, and feeds back the authentication result to the charging pile. The plug-and-charge authentication request is generated by the charging pile in response to the charging request of the electric vehicle. The plug-and-charge authentication request contains the encrypted text of the vehicle identification number of the electric vehicle and the corresponding encryption key.
[0018] This invention also proposes a charging control device, installed in a charging pile, comprising: a charging request receiving unit, used to receive a charging request sent by an electric vehicle in response to the insertion of a charging gun; wherein the charging request includes encrypted text of a vehicle identification number and an encryption key for the encrypted text, the encryption key being obtained by the electric vehicle from a third-party platform that registers its plug-and-charge function;
[0019] The authentication initiation unit is used to send a plug-and-charge authentication request to the third-party platform through the charging pile cloud platform according to the charging request, so as to trigger the third-party platform to perform corresponding authentication; the plug-and-charge authentication request includes the ciphertext and the encryption key;
[0020] The charging control unit is used to initiate or refuse charging of the electric vehicle based on the authentication results fed back by the third-party platform.
[0021] This invention also proposes a charging request device, installed in an electric vehicle, comprising:
[0022] The charging request unit sends a charging request to the charging station when it detects that the charging gun of the charging station has been inserted into the electric vehicle. The charging request contains the encrypted vehicle identification number and the encryption key of the encrypted number. The encryption key is obtained by the electric vehicle from a third-party platform that has registered the plug-and-charge function.
[0023] This invention also proposes a charging authentication device, installed in a third-party platform, comprising:
[0024] A key generation unit is used to generate an encryption key for an electric vehicle that has registered the plug-and-charge function on the third-party platform; the encryption key is used to encrypt the vehicle identification number of the electric vehicle during plug-and-charge authentication.
[0025] An authentication unit is used to perform corresponding authentication based on the plug-and-charge authentication request of the charging pile, and to feed back the authentication result to the charging pile; the plug-and-charge authentication request includes the encrypted text of the vehicle identification number of the electric vehicle and the corresponding encryption key; the plug-and-charge authentication request is generated by the charging pile in response to the charging request of the electric vehicle.
[0026] This invention also proposes a charging control device for a charging pile, including a processor and a memory;
[0027] The memory stores an application program that can be executed by the processor, which enables the processor to execute the charging control method of the charging pile as described above.
[0028] This invention also proposes a computer-readable storage medium storing computer-readable instructions for executing the charging control method of the charging pile as described above.
[0029] This invention also proposes a computer program product, including a computer program / instruction, which, when executed by a processor, implements the steps of the charging control method for the charging pile as described above.
[0030] In summary, the technical solution proposed in this invention involves an electric vehicle obtaining an encryption key from a third-party platform that registers its plug-and-charge function. This encryption key is then used to encrypt the vehicle identification number (VIN) before being sent to the charging pile. The charging pile then includes the encrypted VIN and the encryption key in a plug-and-charge authentication request, which is sent to the third-party platform via the charging pile cloud platform, triggering the third-party platform to perform plug-and-charge authentication. Thus, by having the third-party platform that registers the plug-and-charge function generate the encryption key for the VIN, and by having the third-party platform perform authentication based on the plug-and-charge authentication request carrying the encrypted VIN and the encryption key, a closed-loop logic for charging authentication is achieved. This ensures that the VIN used for charging authentication is consistent with the VIN of the charging vehicle, preventing the theft or misuse of the VIN and thus avoiding incorrect charging billing order binding.

[0038] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0039] Figure 1 This is a schematic flowchart of a charging control method according to an embodiment of the present invention. The method is executed by a charging pile, such as... Figure 1 As shown, this embodiment mainly includes the following steps 101 to 102:
[0040] Step 101: The charging pile receives a charging request sent by the electric vehicle in response to the insertion of the charging gun; wherein the charging request includes ciphertext of the vehicle identification number and an encryption key for the ciphertext, and the encryption key is obtained by the electric vehicle from a third-party platform that has registered the plug-and-charge function.
[0041] In this step, the vehicle identification number (VIN) carried in the charging request is an encrypted VIN. This ensures the security of VIN transmission and prevents VIN theft.
[0042] Specifically, the encryption key used to encrypt the vehicle identification number (VIN) is generated by a third-party platform and must be included in the charging request. This allows the third-party platform to obtain the corresponding decryption key based on the encryption key during subsequent plug-and-charge authentication. This decrypts the ciphertext of the VIN and allows the platform to query the corresponding VIN based on the encryption key. Authentication is then performed based on the consistency between the queried VIN and the decrypted VIN, ensuring that the VIN used for charging authentication matches the actual VIN of the charging vehicle. This prevents the theft or misuse of the VIN and avoids incorrect charging billing order binding.
[0043] In practical applications, the encryption key can be obtained from the third-party platform when the electric vehicle registers the plug-and-charge function, or it can be obtained from the third-party platform when the electric vehicle needs to be charged. For example... Figure 2 As shown, when the latter method is used, in one embodiment, the electric vehicle can specifically obtain the encryption key by using the following steps 201-202:
[0044] Step 201: When the electric vehicle detects the insertion, it sends a plug-and-charge authentication key request to the third-party platform.
[0045] Step 202: Based on the plug-and-charge authentication key request, when the third-party platform determines that the plug-and-charge function of the electric vehicle has been enabled, it generates a unique encryption key and sends it to the electric vehicle.
[0046] In this step, when the third-party platform receives the plug-and-charge authentication key request, it needs to determine whether the electric vehicle that sent the plug-and-charge authentication key request has enabled the plug-and-charge function. Only if the electric vehicle has enabled the plug-and-charge function will an encryption key for plug-and-charge authentication be generated for it. This encryption key will be unique in the third-party platform so that relevant information of the electric vehicle (such as the vehicle identification number) can be queried based on the encryption key.
[0047] Preferably, the encryption key can be a random key, that is, the encryption key is obtained by generating random numbers, but it is not limited to this, as long as it can be ensured that the encryption key is unique in the third-party platform.
[0048] Specifically, the encryption key is used to encrypt the vehicle VIN, which can be achieved using existing encryption methods, and will not be elaborated here.
[0049] The third-party platform mentioned in step 101 is a platform for registering the plug-and-charge function for electric vehicles. In this way, the third-party platform can generate an encryption key for the electric vehicle based on whether the plug-and-charge function has been enabled. This ensures that the encryption key used to encrypt the vehicle VIN during plug-and-charge authentication can only be generated when the plug-and-charge function is enabled, thus preventing charging of electric vehicles without the plug-and-charge function and ensuring the legality of charging electric vehicles.
[0050] In one implementation, the third-party platform can be a vehicle networking platform;
[0051] Accordingly, the charging request further includes a vehicle operator identification code, so that when the charging pile generates a plug-and-charge authentication request, the vehicle operator identification code can be added to the plug-and-charge authentication request, so that the charging pile cloud platform can know which vehicle network platform to forward the plug-and-charge authentication request to based on the vehicle operator identification code in the plug-and-charge authentication request.
[0052] In one implementation, to further improve the reliability of authentication, the charging request may further include the location information of the electric vehicle, so that when a third-party platform performs authentication, it can combine the consistency between the location information of the electric vehicle and the location information of the charging pile.
[0053] Step 102: The charging pile sends a plug-and-charge authentication request to the third-party platform through the charging pile cloud platform according to the charging request, so as to trigger the third-party platform to perform corresponding authentication according to the plug-and-charge authentication request; the plug-and-charge authentication request includes the ciphertext and the encryption key.
[0054] In this step, after receiving a charging request from an electric vehicle, the charging pile needs to generate a plug-and-charge authentication request and send it to the corresponding third-party platform through the charging pile cloud platform. This triggers the third-party platform to perform corresponding authentication based on the content of the plug-and-charge authentication request. In this way, by having the third-party platform perform authentication based on the ciphertext of the vehicle identification number (VIN) and an encryption key generated by the third-party platform that registered the plug-and-charge function for the electric vehicle, a closed-loop logic for charging authentication is achieved. This ensures that the VIN used for charging authentication is consistent with the VIN of the actual charging vehicle, preventing the theft or misuse of the VIN and thus avoiding incorrect binding of charging billing orders.
[0055] In one implementation, such as Figure 3 As shown, after receiving the plug-and-charge authentication request, the third-party platform can specifically perform the corresponding authentication using the following steps 301-302:
[0056] Step 301: Based on the encryption key in the Plug and Charge authentication request, decrypt the ciphertext in the Plug and Charge authentication request, and query the vehicle identification number corresponding to the encryption key from the third-party platform.
[0057] Step 302: If the vehicle identification number obtained by decryption matches the vehicle identification number obtained by query, then authentication is successful; otherwise, authentication fails.
[0058] In one implementation, when the third-party platform is a vehicle-to-everything (V2X) platform, and the charging request further includes a vehicle operator identification code, the plug-and-charge authentication request also needs to include the vehicle operator identification code. Accordingly, the charging pile can specifically use the following method to send the plug-and-charge authentication request to the third-party platform through the charging pile cloud platform:
[0059] The charging pile sends the plug-and-charge authentication request to the charging pile cloud platform, which triggers the charging pile cloud platform to determine the corresponding vehicle network platform based on the vehicle operator identification code in the plug-and-charge authentication request, and then sends the plug-and-charge authentication request to the determined vehicle network platform.
[0060] In one implementation, to further improve the reliability of authentication, when the charging request further includes the location information of the electric vehicle, the plug-and-charge authentication request further includes the location information of the electric vehicle and the location information of the charging pile.
[0061] The location information of the charging pile can be added to the plug-and-charge authentication request by the charging pile itself, or the charging pile cloud platform can add the plug-and-charge authentication request to the third-party platform before forwarding it.
[0062] Accordingly, after receiving the plug-and-charge authentication request, the third-party platform, as follows: Figure 4 As shown, the corresponding authentication can be performed using the following steps 401-402:
[0063] Step 401: Based on the encryption key in the Plug and Charge authentication request, decrypt the ciphertext in the Plug and Charge authentication request, and query the vehicle identification number corresponding to the encryption key from the third-party platform.
[0064] In this step, the third-party platform will obtain the corresponding decryption key from this platform based on the encryption key in the Plug and Charge authentication request, and then decrypt the ciphertext in the Plug and Charge authentication request based on the decryption key.
[0065] Step 402: If the vehicle identification number obtained by decryption is consistent with the vehicle identification number obtained by query, and the location information of the electric vehicle and the location information of the charging pile in the plug-and-charge authentication request are consistent, then the authentication is successful; otherwise, the authentication fails.
[0066] In step 402, it is necessary not only to determine the consistency of the vehicle identification number, but also the consistency of the electric vehicle's location information and the charging pile's location information. Only when both of these consistency requirements are met can the authentication be considered successful, thereby further enhancing the accuracy and reliability of the authentication results.
[0067] Specifically, the location information can be GPS location information or location information obtained through other means, which will not be elaborated here.
[0068] Step 103: The charging pile starts or refuses to charge the electric vehicle based on the authentication result fed back by the third-party platform.
[0069] This step is used to determine whether to start the charging process for the electric vehicle based on the authentication results fed back by the third-party platform. This ensures that charging of the electric vehicle is only started when authentication is successful, thus ensuring that the VIN used to bind the corresponding charging billing order is consistent with the VIN of the actual charging object, thereby avoiding the problem of incorrect binding of charging billing orders.
[0070] Specifically, if the authentication result returned by the third-party platform is successful, charging of the electric vehicle will be initiated; otherwise, charging of the electric vehicle will be refused.
[0071] In practical applications, when charging of the electric vehicle is refused, the charging station can be used to notify the charging user of the corresponding authentication failure message.
[0072] Based on the above embodiments, it can be seen that the charging control method embodiments can ensure that the vehicle identification number used for charging authentication is consistent with the vehicle identification number of the actual charging vehicle, avoiding the theft or misuse of the vehicle identification number, and thus avoiding the problem of incorrect binding of charging billing orders. Based on the above charging pile charging control method embodiments, this embodiment of the invention also implements a charging request method, which is executed by an electric vehicle, specifically including:
[0073] When an electric vehicle detects the insertion of a charging gun into a charging station, it sends a charging request to the charging station. The charging request contains encrypted information of the vehicle identification number and an encryption key for the encrypted information. The encryption key is obtained by the electric vehicle from a third-party platform that has registered the plug-and-charge function.
