Technical Field

[0001] This invention belongs to the field of new energy vehicle charging technology, specifically relating to an automatic charging control method based on an on-board system. Background Technology

[0002] Currently, electric vehicle charging requires users to manually operate a mobile app to search for charging stations, scan a code to start the process, and complete payment. This process is cumbersome and fragmented. Users need to switch between multiple apps, which cannot achieve a unified charging experience. Integrating charging control functions into the vehicle system to automate the entire process from low battery warning to charging completion is key to improving the user experience. Summary of the Invention

[0003] The present invention aims to provide an automatic charging control method based on an in-vehicle system, so as to realize the automatic control of the entire charging process on the in-vehicle end.

[0004] An automatic charging control method based on an in-vehicle system includes steps such as power monitoring, charging pile search, intelligent selection, navigation guidance, automatic connection, information interaction, charging monitoring, and automatic payment.

[0005] The present invention also provides an on-board charging control system, including a power monitoring unit, a communication unit, a navigation unit, a display unit, and a control unit.

[0006] Compared with existing technologies, this invention has the following advantages: it realizes full-process vehicle-side automation of charging; reduces user operations and improves the user experience; supports intelligent recommendation of the best charging pile; and provides a complete solution for OEM pre-installation cooperation.

Detailed Implementation Example

[0009] like Figure 1 As shown, this embodiment provides an automatic charging control method based on an on-board system.

[0010] Step S1: The vehicle system monitors the battery level in real time. When the SOC is below 20%, it automatically triggers the charging request.

[0011] Step S2: The vehicle system connects to the cloud charging service platform via the 4G network, searches for available charging piles within a 3-kilometer radius, and obtains the location, type, price, and availability status of 10 charging piles.

[0012] Step S3: Based on the user's preset preferences and recommendation algorithm, the vehicle system selects the nearest and most affordable charging station and pushes a confirmation option to the vehicle's display screen. The user clicks to confirm.

[0013] Step S4: The in-vehicle navigation system plans the driving route and guides the vehicle to the target charging station.

[0014] Step S5: When the vehicle arrives at the charging area, the onboard system automatically establishes a communication connection with the charging pile via Bluetooth.

[0015] Step S6: The vehicle system sends the encrypted VIN code, battery type, rated voltage 400V, current SOC 18%, battery temperature 25 degrees Celsius, and maximum allowable charging current 200A to the charging pile.

[0016] Step S7: The charging pile returns a confirmation message, the vehicle system sends an unlock command to the vehicle control module, and the charging port cover opens automatically.

[0017] Step S8: During the charging process, the vehicle system receives charging status data sent by the charging pile in real time and displays the current power of 60KW, the amount charged is 5KWH, and the estimated remaining time is 35 minutes on the display screen.

[0018] Step S9: Charging is complete, and the vehicle system sends a stop charging command to the charging station.

[0019] Step S10: The vehicle system receives a charging bill of 45 yuan, automatically completes the settlement through the linked WeChat Pay, and pushes a charging report to the user.

[0020] Industrial applicability Each step of this invention can be implemented on existing in-vehicle systems and T-BOXs without requiring additional hardware. Those skilled in the art can implement this invention without inventive effort based on the description in this specification. This invention can provide OEMs with differentiated intelligent charging functions, enhancing product competitiveness and possessing broad industrialization prospects.
