[0103] like Figure 2 As shown, the charging method of the vehicle-to-charging pile contactless charging system of this embodiment includes the following steps:

[0104] The binding of mobile app and user vehicle;

[0105] like Figure 3As shown, after logging into the mobile APP, the user collects the vehicle's unique information VIN / SN through the information collection module and transmits the collected data to the data storage module in the mobile APP for storage.

[0106] Binding the mobile app to the charging station;

[0107] like Figure 4 As shown, after the charging pile is powered on, its Bluetooth unit sends a Bluetooth broadcast. When the user's mobile phone is close to the charging pile and the phone's Bluetooth unit is turned on, the phone's Bluetooth unit searches for the Bluetooth of nearby charging piles. The user selects the Bluetooth of the corresponding charging pile and establishes a connection with it. The mobile APP module verifies the authorization code with the charging pile through Bluetooth to confirm the legality and correctness of the authorization code. If the verification is successful, it means that the authentication is passed and subsequent data communication can be carried out.

[0108] Preferably, as specific embodiments of the authorization verification between the mobile APP module and the charging pile via Bluetooth in the embodiments of the present invention, there are, but are not limited to, the following two:

[0109] The mobile app module sends the authorization code generated by the control management unit to the charging pile via Bluetooth communication. After receiving the authorization code, the charging pile's Bluetooth unit verifies it using its control management unit. If the local authorization code on the charging pile matches the one sent by the mobile app, the charging pile returns a verification success message to the mobile app, and authentication is successful, entering the data communication phase. The mobile app then sends the authorization code generated by the control management unit to the charging pile via Bluetooth communication. The charging pile's Bluetooth unit verifies the received authorization code using its control coordination unit. If the verification fails, the charging pile returns a verification failure message to the mobile app. Upon receiving the message from the charging pile, the mobile app proactively sends a "Start Card Swiping Authentication" message. The user requests the charging pile. After receiving the request from the mobile app, the charging pile enters the "waiting for card authentication" state. The user brings the NFC authorization card close to the card reader of the charging pile. After obtaining the information of the NFC authorization card, it compares it with the local information of the data storage unit. After the comparison is successful, the charging pile app returns a "card swipe successful" message to the mobile app. The mobile app sends the authorization code generated by the control management unit to the charging pile through the Bluetooth communication unit. After receiving it, the charging pile Bluetooth unit saves it to the charging pile data storage unit and sends a "authentication code saved successfully" message to the mobile app, and then proceeds with subsequent data communication.

[0110] Data communication between charging stations and vehicles;

[0111] like Figure 5As shown, the user vehicle's Bluetooth unit continuously broadcasts messages. When the vehicle approaches the charging station, the charging station's Bluetooth unit actively searches for the Bluetooth broadcast corresponding to the vehicle's VIN and establishes a connection. After the Bluetooth connection is successful, the charging station's Bluetooth sends an "authentication request" to the vehicle's Bluetooth. The "authentication request" message contains the encrypted vehicle VIN and key. After receiving the message, the vehicle's Bluetooth unit's control and management unit verifies the received request message. If the verification is successful, the vehicle returns an "authentication successful" message to the charging station. Successful authentication means that the authentication is passed and subsequent data communication can proceed.

[0112] The charging station starts charging the vehicle seamlessly.

[0113] like Figure 5 As shown, after Bluetooth authentication between the charging pile and the vehicle is successful, the vehicle's Bluetooth sends a charging gun connection status message to the charging pile. The user inserts the charging gun of the charging pile into the vehicle's charging dock. The insertion status information of the charging gun on the charging dock is sent by the vehicle's TBOX module to the vehicle's Bluetooth unit. The vehicle's Bluetooth unit forwards the real-time charging gun connection status to the charging pile via Bluetooth. Only when the charging pile receives a charging gun connection status message of "charging gun fully connected" and the charging pile also detects that the charging gun connection is normal, the charging pile's control and management unit controls the charging gun to output CP, enabling seamless charging for vehicle startup.

[0114] Preferably, the specific embodiments of the seamless charging between the charging pile and the vehicle in the embodiments of the present invention include, but are not limited to, the following two:

[0115] After the seamless charging is started, the vehicle's Bluetooth sends the vehicle's battery SOC message to the charging pile. The charging pile receives the message and stores it in the charging pile's data storage unit. The control and management unit then displays the vehicle's battery SOC data to the outside world according to the specific application of the charging pile.

[0116] After the seamless charging is started, the vehicle sends the charging reservation time to the charging pile via Bluetooth. The charging pile receives the data via Bluetooth and stores it in the charging pile data storage unit. The control and management unit then starts a countdown. When the countdown time is up, the control and management unit controls the charging gun to output CP to charge the vehicle at the scheduled time.

[0117] In summary, the advantages of this invention are as follows:

[0118] Bluetooth connectivity and proprietary protocol: Utilizing Bluetooth technology and proprietary protocol, the system enables rapid authentication between the vehicle and the charging station, avoiding repeated user operations and improving the charging experience.

[0119] Automatic information transmission: Vehicle information and charging reservations are automatically transmitted to the charging station via Bluetooth. The charging station can start charging directly after recognition without manual intervention.

[0120] Real-time monitoring and feedback: The vehicle's battery status and scheduled charging information are sent to the charging station in real time, enhancing the user's control over the charging process.

[0121] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
