Description

A non-sensing charging payment method and system for an electric vehicle, and a cockpit system

[0001] The present application claims priority to Chinese Patent Application No. 202410472831.2, filed on April 18, 2024, and entitled "A non-sensing charging payment method and system for an electric vehicle, and a cockpit system", the entire disclosure of which is incorporated herein by reference. TECHNICAL FIELD

[0002] The present application relates to mobile payment technology, in particular to a non-sensing charging payment method for an electric vehicle, a non-sensing charging payment system for an electric vehicle, and a cockpit system. BACKGROUND

[0003] A non-sensing charging payment method for an electric vehicle has been proposed in the field of charging payment for Internet of Vehicles. This non-sensing charging payment method identifies a ground parking space through an image related to the location of the electric vehicle, and then determines the corresponding charging gun. The electric vehicle then initiates a charging request to the specified charging gun. Based on the relevant information such as the electric vehicle identification information, charging time, and charging amount, the charging fee is settled and then the non-sensing payment is realized.

[0004] Problems exist in the existing non-sensing charging payment method for an electric vehicle, including:

[0005] (1) The binding of the charging pile and the electric vehicle needs to be completed in advance, which is suitable for charging the electric vehicle at a commonly used charging pile, but cannot realize non-sensing charging with mixed insertion of multiple guns in a public charging station.

[0006] (2) The charging gun usually has a long charging cable, which can be used in the adjacent parking space. When electric vehicle B uses charging pile A for charging, the camera will identify that electric vehicle A is charging, which will cause incorrect accounting.

[0007] (3) It generally relies on a communication gateway, so the charging pile needs to be connected and modified, which involves a certain modification cost and has a limited scope of application. The scheme based on the communication gateway is not suitable for the scenario where the charging pile is connected independently through 4G. On the other hand, the VIN (Vehicle Identification Number) communication between the electric vehicle and the charging pile is in plaintext, which is vulnerable to man-in-the-middle attacks to change and counterfeit, thereby cheating the cloud server for charging and harming the interests of others.

Alterations, modifications, and improvements to such embodiments, which occur to the skilled in the art, are herein, within the spirit and scope of the application. In addition, while the present application is described in connection with various embodiments / implementations, it should be recognized that features from any of the embodiments / implementations can be employed with any other embodiment / implementation as can be desired and / or advantageous. Therefore, the following detailed description is not intended to be limiting, but is merely illustrative.

[0087] The terms such as "have" and "include" indicate that the technical scheme of the present application does not exclude the presence of other elements (modules) and steps not directly or explicitly expressed in the specification and claims, in addition to the elements (modules) and steps directly and explicitly expressed in the specification and claims.

[0088] FIG. 1 is a schematic flowchart of the method for inductive charging payment of the electric vehicle of the present application.

[0089] As shown in FIG. 1, the method for inductive charging payment of the electric vehicle of the present application is implemented by the electric vehicle and the charging service system, and the method includes the following three steps in brief:

[0090] The charging station determination step S100: the electric vehicle acquires the charging station information of the available charging stations in the surrounding area from the charging service system according to the position information of the electric vehicle, and determines the charging station to be charged according to the charging-related habit parameters of the electric vehicle and the bound payment card to recommend the most suitable charging station in the surrounding area on the electric vehicle side;

[0091] The charging matching step S200: the electric vehicle is navigated to the charging station determined by the user, and the electric vehicle is paired with the charging gun in the charging station through image detection pairing and radar detection pairing to realize charging (i.e., including the preliminary matching step realized by image detection, the accurate matching step realized by radar, and the charging step), and the charging parameter data detected by the electric vehicle itself and the charging parameter data monitored by the charging service system are verified at the same time; and

[0092] The charging fee payment step S300: after the charging is completed, the charging service system sends the charging fee data to the electric vehicle, the electric vehicle compares the charging fee data of itself, and in the case of successful comparison, the electric vehicle initiates a payment request to the payment platform and completes the payment of the charging fee.

[0093] In the following, the specific contents of the charging station determination step S100, the charging matching step S200, and the charging fee payment step S300 are described.

[0094] In the charging station determination step S100, under the premise of ensuring user information not to be disclosed, the most suitable charging station is recommended to the user by the cockpit system of the electric vehicle using the electric parameters in the cockpit system, charging fee data, the list of deduction cards bound by the cockpit system, and other information, so as to provide a better charging experience. The specific flow of the charging station recommendation step S100 includes:

[0095] 1) The cockpit system initiates a request to the charging service system for obtaining the charging station information of the surrounding available charging stations based on the location information, wherein the request can also include obtaining the preferential information of the charging station, etc.

[0096] 2) After receiving the request, the charging service system returns the charging station information of the surrounding available charging stations to the cockpit system;

[0097] 3) After receiving the charging station information, the cockpit system generates a recommended station list and reasons according to the cockpit system charging parameters, user usage habits, and the list of deduction cards bound by the cockpit system, such as slow charging to reduce battery wear, low cost, payment discount, etc.; and

[0098] 4) The cockpit system sorts according to the user selection tendency prediction and presents to the user through voice / screen, etc.

[0099] In the present application, the matching and recommendation of the charging station are performed on the cockpit system side according to the obtained charging station information. Compared with the scheme in the prior art that matches and recommends user data on the platform side, not only the user privacy can be protected, but also the analysis based on the full charging fee data of the user can be performed. For example, the charging fee data of the user at a certain brand station is only partial, and there is usually a competitive barrier between platforms, which does not want to share data for user recommendation, so that the recommended content does not meet the user demand.

[0100] FIG. 2 is a schematic diagram of the specific flow of the charging matching step S200 in the electric vehicle non-inductive charging payment method of the present application.

[0101] As shown in FIG. 2, the charging matching step S200 in the electric vehicle non-inductive charging payment method of the present application specifically includes the following steps:

[0102] S201: Determine the charging station through positioning and driving image information, etc.

[0103] S202: The cockpit system obtains the charging station digital model of the charging station from the charging service system, and on the other hand, switches the deduction card bound for charging payment to the corresponding deduction card with preferential treatment according to the deduction card preferential treatment provided by the charging station;

[0104] S203: The cockpit system determines the position and direction of the vehicle based on the image information captured by the camera and the comparison with the charging pile digital model.

[0105] S204: The cabin system determines the corresponding charging gun through the angle and position of the charging gun in the image information;

[0106] S205: The vehicle-mounted radar detects the position and direction of the charging gun in real time to determine the corresponding charging gun (S204 and S205 can be exchanged in sequence, or they can be performed simultaneously);

[0107] S206: The cabin system determines the corresponding charging gun of the electric vehicle through the image and radar, and initiates a request to start charging to the charging service system;

[0108] S207: The charging service system returns a start charging response and sends a charging instruction to the charging gun to start charging;

[0109] S208: The charging service system monitors the charging process in real time, such as monitoring the charging current, charging voltage, and other charging parameters, and transmits the charging parameter data to the cabin system;

[0110] S209: The cabin system checks the returned charging parameter data with the charging parameter data (current, voltage, etc.) detected by itself (of course, as a transformation method, this process can also be uploading data from the electric vehicle to the charging service system for verification);

[0111] S210: If the verification is consistent, it means that the charging is successful;

[0112] S211: If the verification is inconsistent, it means that the charging has an abnormal situation (for example, the charging power is inconsistent, or the charging has not started, etc., which means that the correspondence between the electric vehicle and the charging gun is pairing error), then an error is immediately reported and action is taken to correct it (for example, closing the current charging gun and opening the next selected charging gun for verification).

[0113] When the user uses the non-inductive charging payment, the existing technology can only bind one deduction card or use the default payment sequence for payment, and cannot select the deduction card to enjoy the discount. In the present application, the charging station discount is combined with the user's selection of the charging station (determined by positioning and driving image), and the cabin system can automatically switch according to the deduction card bound by itself.

[0114] In the charging fee payment step S300, the charging service system sends the charging fee data to the cabin system for comparison after the charging is completed, and signs the data to send to the payment platform to initiate payment and avoid transaction denial. The specific process includes:

[0115] 1) The charging station collects charging cost data in real time, including charging time, power, cost, etc. The charging service system stores the collected charging cost data in the charging service system to ensure data integrity and security;

[0116] 2) The charging service system sends charging parameter data to the cockpit system at a certain time, for example, sets a timing task to send charging cost data to the cockpit system at a certain time point in the charging service system;

[0117] 3) The cockpit system compares the charging cost data, that is, compares the received charging cost data with the charging cost data recorded in the cockpit system to verify the accuracy and integrity of the charging cost data;

[0118] 4) After the charging cost data comparison is successful, the cockpit system signs the charging cost data using a private key to ensure the authenticity and source of the data;

[0119] 5) The cockpit system uploads the signed charging cost data to the payment platform and initiates a payment request;

[0120] 6) After receiving the data, the payment platform verifies the signature of the charging cost data using the public key corresponding to the private key to ensure the authenticity and source of the data, and in the case of successful verification, performs corresponding payment processing based on the charging cost data; and

[0121] 7) The payment platform feeds back the payment processing result to the charging service system and the cockpit system.

[0122] In the charging cost payment step S300, through the signature and comparison of the charging cost data and the timing sending and comparison of the charging parameter data, the denial behavior of the transaction can be effectively prevented. Because once the transaction denial occurs, the authenticity of the transaction can be traced and verified by comparing the charging cost data of the cockpit system with the charging cost data stored in the charging service system.

[0123] FIG. 3 is a flowchart of a non-inductive charging payment method of an electric vehicle according to an embodiment of the present application.

[0124] As shown in FIG. 3, the non-inductive charging payment method of the electric vehicle according to an embodiment of the present application is realized through the cockpit system and the charging service system of the electric vehicle, and the method includes the following steps:

[0125] S1: The GPS system of the cockpit system starts to work and accurately obtains the position information of the electric vehicle;

[0126] S2: The cockpit system uploads the positioning to the charging service system and obtains the available charging stations nearby from the charging service system;

[0127] S3: Under the premise of ensuring that user information is not leaked, the cabin system recommends a charging station that is most suitable in terms of charging conditions to the user from nearby available charging stations according to charging parameters of the cabin system, user usage habits, a list of non-inductive deduction cards bound by the cabin system, and the like, to provide a better charging experience. For example, if an electric vehicle only supports slow charging, then fast charging station information is filtered. For another example, if it is predicted according to accumulated data of the electric vehicle that the user will charge overnight, then a slow charging station is recommended to reduce battery wear;

[0128] S4: The vehicle-mounted system is navigated to the selected charging station, and a charging station digital model of the charging station is obtained from the charging service system;

[0129] S5: If the charging station provides an A-line deduction card offer, the cabin system will switch the bound non-inductive deduction card to an A-line deduction card according to the offer provided by the charging station;

[0130] S6: The camera of the electric vehicle starts to work, captures images of driving, and provides the images to the cabin system;

[0131] S7: The cabin system pre-processes the video stream and / or images, such as noise reduction, enhancement, and the like (to facilitate subsequent algorithm processing);

[0132] S8: After the cabin system processes the images data through algorithms for image recognition and processing, feature images are obtained, the feature images are matched with the charging station digital model to determine the position and direction of the electric vehicle, and the correspondence relationship between the electric vehicle and the charging gun is judged, wherein the charging station digital model refers to a template image formed by pre-shooting the plug-in image of the charging gun in each direction of the charging station, and then training to obtain a digital model. By matching the real-time image with the charging station digital model, the correspondence relationship between the electric vehicle and the charging gun of the charging station can be determined;

[0133] S9: The radar of the electric vehicle starts to work, detects the position and direction of the charging gun in real time, and provides the radar data to the cabin system;

[0134] S10: The cabin system accurately pairs the charging gun and the electric vehicle according to the radar data, and realizes the correspondence relationship pairing between the electric vehicle and the charging gun;

[0135] S11: After confirming that the correspondence relationship pairing between the electric vehicle and the charging gun is successful, the cabin system initiates a request to start charging to the charging service system, and the charging service system returns a start charging response;

[0136] S12: After the charging starts, the charging service system monitors the charging process in real time, and transmits charging parameter data such as monitored charging current and charging voltage to the electric vehicle;

[0137] S13: The electric vehicle checks the returned charging parameter data with the charging parameter data (such as charging current, charging voltage, etc.) detected by itself. If an abnormal situation occurs (i.e., the corresponding relationship between the charging parameters of the electric vehicle itself and the charging parameters returned from the charging service system is incorrectly paired), an error is immediately reported and corresponding corrections are taken.

[0138] S14: After the charging is completed, the charging service system sends charging cost data to the electric vehicle;

[0139] S15: The electric vehicle compares the received charging cost data with the charging cost data recorded in the cabin system;

[0140] S16: After the charging cost data is matched, the charging cost data is signed using a private key, and the signed charging cost data is uploaded to the payment platform to initiate a payment request;

[0141] S17: After the payment platform receives the charging cost data, the signature of the charging cost data is verified using a public key to ensure the authenticity and source of the data. At the same time, the payment platform will perform corresponding payment processing according to the charging cost data;

[0142] S18: After the payment platform completes the payment processing, the results are fed back to the charging service system and the electric vehicle;

[0143] S19: The cabin system automatically records data related to each charging, such as charging time, charging capacity, charging cost, etc.; and

[0144] S20: After the above data is analyzed, it can be used to optimize charging strategies and can also be used to subsequently recommend the most suitable charging station, thereby providing a better charging experience.

[0145] In the above process shown in FIG. 3, two detection pairing methods, image detection pairing (S6-S8 in FIG. 3) and radar detection pairing (S9-S10 in FIG. 3), are used to realize the pairing of the electric vehicle and the charging gun. These two detection pairing methods are preferably used together, or one of them can be selected according to specific needs.

[0146] The case where the two detection pairing methods are used together is suitable for scenarios that require higher accuracy and stability, i.e., using visual algorithms and radar detection to pair at the same time. Visual algorithms mainly rely on cameras to determine the charging gun, while radar detection detects the position and attitude of the charging gun by transmitting signals and receiving reflected signals. The two complement each other and can provide more comprehensive and accurate information to improve the success rate of pairing.

[0147] The two detection pairing modes are adopted alternatively, which is suitable for scenarios considering cost, power consumption or real-time requirements, etc. In such scenarios, one of the methods can be selected for pairing. For example, only using the visual algorithm has low hardware cost, while in other scenarios, radar detection can provide more direct and real-time information.

[0148] Next, the specific process of the radar detection pairing mode (S9-S10 in FIG. 3) is described.

[0149] As an example, the radar detection pairing mode includes the following steps, for example:

[0150] The radar device emits signals to the surroundings and receives reflected signals. By analyzing the time difference of the reflected signals, the distance and position of the target object can be calculated;
