A method for controlling wireless charging is applied to the wireless charging receiver. The wireless charging receiver comprises a plurality of receiving coils, and the plurality of receiving coils at least comprise a first type of coil and a second type of coil. The method for controlling wireless charging comprises: controlling the plurality of receiving coils to be in a charging receiving mode and/or a signal communication mode; taking a coil in the signal communication mode among the plurality of receiving coils as the first type of coil to communicate with a wireless charging transmitter; and taking a coil in the charging receiving mode among the plurality of receiving coils as the second type of coil to receive charging energy transmitted by the wireless charging transmitter.

Wireless charging receiver and wireless charging system, and method and apparatus for controlling wireless charging

A wireless charging reception circuit, a method, electronic device and a wireless charging system are described. In the wireless charging reception circuit, a control circuit may control a rectifying circuit to rectify electric signals transmitted by a first resonance circuit and/or a second resonance circuit. Since the rectifying circuit outputs different voltages after rectifying the electric signals transmitted by the different resonance circuits, the control circuit may controls the rectifying circuit to rectify the electric signals transmitted by the different resonance circuits to adjust the output voltages of the rectifying circuit.

Wireless charging reception circuit, method, electronic device and wireless charging system for transmitting electric energy through electromagentic induction to charge a battery

An apparatus for wireless charging includes a charger, a wireless transmitting controller and a transmitting coil. The charger is configured to output a first voltage to the wireless transmitting controller. The wireless transmitting controller is configured to boost the first voltage to obtain a second voltage, and the second voltage is greater than the first voltage. The transmitting coil is configured to perform a wireless charging capability output at the second voltage. A terminal includes a wireless receiving coil, a wireless receiving controller and a step-down processor. The wireless receiving coil receives the charging signal from an apparatus for wireless charging. The wireless receiving controller processes the charging voltage to obtain a third voltage of direct current; and the step-down processor steps down the third voltage to obtain a fourth voltage within a charging range acceptable by the terminal and charge a battery of the terminal by the fourth voltage.
