A method for wireless charging, the method being applied to a power management apparatus, characterized in that the method comprises: sending, in response to detecting a first voltage in a normal wireless charging mode output by a wireless charging receiver, fast wireless charge identification information to the wireless charging receiver; determining a charging request based on acknowledgment information received from the wireless charging receiver, wherein the acknowledgment information is generated by a wireless charging transmitter in response to the fast wireless charge identification information according to the voltage and current capability information of the charger; sending the charging request to the wireless charging receiver; and setting an input current of the power management apparatus according to the charging request and a charging efficiency, wherein the determining a charging request based on acknowledgment information received from the wireless charging receiver comprises: determining the charging request based on the acknowledgment information received from the wireless charging receiver if the acknowledgment information is received within a first time period after sending the fast wireless charge identification information, and wherein the determining the charging request based on the acknowledgment information comprises: determining, when the acknowledgment information is fast wireless charge acknowledgment information, the charging request as a fast wireless charging request; and determining, when the acknowledgment information is normal wireless charge acknowledgment information, the charging request as a normal wireless charging request, further comprising: determining the charging request as a normal wireless charging request when the acknowledgment information is not received within a first time period after sending the fast wireless charge identification information. sending, in response to detecting a first voltage in a normal wireless charging mode output by a wireless charging receiver, fast wireless charge identification information to the wireless charging receiver;
