Preferably, the above-mentioned mechanical drive system includes a drive mechanism in which the X-direction drive motor drives the lead screw to move and a drive mechanism in which the Y-direction drive motor drives the lead screw to move; the above-mentioned wireless communication module adopts a GPRS or GSM module; the above-mentioned controller A adopts an ECU, and the above-mentioned The above-mentioned controller B adopts PLC.

Preferably, the above-mentioned electric energy transmitting end is fixedly connected to the frame, and the X-direction and Y-direction positions are adjusted through the mechanical drive system on the frame, so that the position of the transmitter induction coil and the receiver induction coil can be correctly matched, and the charging efficiency is improved.

Use process: When the electric vehicle to be charged drives into a specific charging position and stops, the user sends a charging demand through the GUI interface, and the demand will be received by the on-board controller A, and send a charging request signal to the power transmitter through the wireless communication module A, After the wireless communication module B of the power transmitter receives the communication signal from the vehicle, it transmits the signal to the controller B of the power transmitter. Due to the inevitable error of the parking position, it is impossible for the induction coil of the power transmitter and the induction coil of the receiver to be 100% positive. There is a certain deviation in the matching, thereby reducing the efficiency of inductive power transmission. In order to compensate for the leakage inductance caused by this deviation, the controller A sends a control command and transmits it to the object recognition sensor connected to the controller B. The object recognition sensor will automatically detect The position of the induction coil of the on-board receiver of the electric vehicle, and the signal is transmitted to the charging controller B of the electric energy transmitter, and the controller B calculates the vertical displacement difference ΔX and the center position of the induction coil of the transmitter and the center of the induction coil of the vehicle receiver ΔY, and then the controller B issues a control command to control the X-direction drive motor and the Y-direction drive motor in the mechanical drive system to rotate a specific number of revolutions, drive the screw nut pair connected to it, and then drive the emitter induction coil X-direction and Y direction movement, when the object recognition sensor detects that the vertical displacement difference ΔX and ΔY between the center position of the transmitter induction coil and the center position of the vehicle receiver induction coil becomes 0, the mechanical drive system stops working, and the transmitter induction coil and the vehicle receiver After the adaptive matching of the body induction coil is completed, the controller B sends an instruction to control the charging control circuit B and the controller A sends an instruction to control the charging circuit A to perform inductive charging.

The power level signal of the rechargeable battery is transmitted to the vehicle-mounted controller A. After the charge is fully charged, the vehicle-mounted controller A sends a charging completion command, and transmits the command to the wireless communication module B of the power transmitter through the wireless communication module A, and the wireless communication module B then Send the instruction to the charging controller B. After receiving the instruction, the charging controller B will automatically terminate the charging, and feed back the charging completion prompt to the vehicle-mounted controller A and the GUI interface through the wireless communication module B, and at the same time control the driving motors of the mechanical drive system , so that the induction coil at the transmitting end returns to the preset default position to complete the charging service.

If the user requests to interrupt the charging service in the middle, he only needs to send a request to interrupt the charging through the GUI interface. At this time, the vehicle-mounted controller A sends a charging interruption command, and transmits the command to the wireless communication module B of the power transmitter through the wireless communication module A. Wireless communication Module B then sends the command to the charging controller B. After receiving the command, the charging controller B immediately controls the termination of charging, and at the same time controls the driving motors of the mechanical drive system to make the transmitter induction coil return to the preset default position and complete the interrupt request. .
