  "textContent": "Disclosed are a power matching method and apparatus for wireless charging, and a wireless charging apparatus. The method comprises: receiving first sensed information sensed from a transmitting coil of a wireless transmitting terminal; detecting, according to the first sensed information, whether a resonant frequency is changed; and when the resonant frequency is changed, adjusting the capacity of a capacitor in the transmitting coil of the wireless transmitting terminal and/or adjusting the inductance of an inductor in the transmitting coil, so that the transmitting power of the wireless transmitting terminal matches the receiving power of a wireless receiving terminal. The first sensed information comprises a first sensed voltage value or a first sensed current value. According to the method, the problems of decrease in charging efficiency and heating of the wireless receiving terminal caused by the change in resonant frequency can be effectively avoided.
