Abstract: A wireless charging apparatus of a wireless charging system obtains, in a charging period, channel information of a transmission channel and a waveform parameter used to indicate a waveform of an electromagnetic wave signal; generates a target electromagnetic wave signal based on the channel information and the waveform parameter; and sends the target electromagnetic wave signal to a to-be-charged device through the transmission channel. The channel information includes signal attenuation and a transmission delay that are of an electromagnetic wave signal transmitted through the transmission channel. The to-be-charged device converts the received target electromagnetic wave signal into a direct current signal, and performs charging based on the direct current signal. The target electromagnetic wave signal determined by the wireless charging apparatus can adapt to channel transmission.
