AI Technical Summary
Technical Problem
In wireless charging of electric vehicles, it is difficult for users to visually align the center of the transmitting unit and the receiving unit, resulting in a decrease in charging efficiency and speed.
Method used
By measuring the distance between the center points of the transmitting and receiving units, a voltage distance sound meter is generated. The receiving unit collects the induced voltage in real time and outputs a prompt sound to guide the user to adjust the position to achieve alignment.
Benefits of technology
It improves the accuracy and efficiency of wireless charging for electric vehicles, enabling users to intuitively and effectively align the charging position and avoid insufficient charging due to inaccurate alignment.

Abstract
The embodiment of the application discloses a wireless charging alignment control method, comprising the following steps: measuring the induced voltage of a receiving coil and generating a corresponding voltage-distance sound table according to the different center point distances between a transmitting unit and a receiving unit of an electric vehicle, and introducing the receiving unit; the receiving unit collects the induced voltage in real time, queries the voltage-distance sound table and outputs the corresponding prompt sound, and starts the charging mode after the alignment prompt sound is output. The relationship between the center point distance and the induced voltage is obtained through actual test, the size of the center point distance is prompted through different prompt sounds, the electric vehicle is easily aligned through the sound prompt operation, which is more intuitive and more effective, and the problem that the user is difficult to align the center of the transmitting unit and the receiving unit of the electric vehicle through visual observation is solved.
