A method for implementing temperature control for a wireless charging system comprises the following steps: (1) initializing a power control marker to be an initial value; (2) calculating a power loss; (3) a transmission end determining whether a value of the power loss is greater than a preset power loss threshold, and if so, proceeding to step (4), otherwise, the transmission end regulating an operation frequency according to an actual data packet sent by a receiving end, and proceeding to step (2); and (4) the transmission end determining whether a received power value of the receiving end is less than a preset received power threshold, and if so, the transmission end performing no regulation of the operation frequency, and exiting the step, otherwise, the transmission end regulating the operation frequency, and proceeding to step (2). The method for implementing temperature control for a wireless charging system solves the problem in which a charging current of a transmission end is excessively large, and board components at the transmission end have an excessively high temperature, thereby effectively reducing heat generation of components at transmission ends, and ensuring normal and stable system operations.
