The invention provides a wireless fast charging system and method for an electric vehicle. The wireless fast charging system comprises a battery pack, a wireless charging receiving module, at least one wireless charging transmitting module, a battery management controller and a charging management module. The charging management module controls the working state of the wireless charging transmitting module; the wireless charging transmitting module is used for transmitting electric energy in an external power supply to the wireless charging receiving module; the wireless charging receiving module receives the electric energy transmitted by the wireless charging transmitting module and transmits the electric energy to the battery pack, and the battery pack supplies power to the electric vehicle; the battery management controller is connected with the battery pack, is used for calculating the SOC of the battery pack, and is in wireless communication connection with the charging management module; and the battery management controller or the charging management module controls the number of the wireless charging transmitting modules needing to work. According to the technical scheme, the state of the battery pack is fed back to the charging pile in real time through wireless communication, the output power is controlled, the charging efficiency is improved, resource waste is prevented, and an efficient and convenient wireless charging mode is achieved.
