A transmit end, a receive end, a method, and a system for wireless charging are provided, and are applied to the field of electric vehicles. A transmit-end controller (101) compares an actual output current of an inverter (HI) with a preset upper limit value of an output current of the inverter (HI), and controls an output voltage of the inverter (HI) based on a comparison result to adjust a current of a transmit coil (Lp), so that the actual output current of the inverter (HI) is less than or equal to the preset upper limit value of the output current of the inverter (HI). A receive-end controller (201) receives a sampled value of the current of the transmit coil (Lp) that is sent by the transmit-end controller (101), and update a reference value of the current of the transmit coil (Lp) when a difference between the sampled value of the current of the transmit coil (Lp) and the reference value of the current of the transmit coil (Lp) is greater than or equal to a preset value, so that the actual output current of the inverter (H1) of the transmit end is less than or equal to the preset upper limit value of the output current of the inverter (HI). The receive end interacts with the transmit end, to achieve better control, and enable the receive end to have a large adjustment range of the current of the transmit coil while it is ensured that the output current of the inverter (HI) does not exceed the preset upper limit value.
