Classification: CPC H | IPC H

Claim 13:
14. The wireless charging device according to claim 5, wherein
when the to-be-charged device detected by the first charging unit through induction and the to-be-charged device detected by the second charging unit through induction are a same to-be-charged device, the same to-be-charged device is the target device, and the first electromagnetic coupling strength is greater than or equal to a first threshold,
the first controller is further to control the first inverter circuit connected to the first target transmitter coil to output a first high-frequency signal;
the first inverter circuit connected to the first target transmitter coil is further to generate the first high-frequency signal and output the first high-frequency signal to the corresponding first target transmitter coil; and
the first target transmitter coil is further to receive the first high-frequency signal, generate a first charging signal under excitation by the first high-frequency signal and transmit the first charging signal to the target device to charge the target device.
