Abstract
The present disclosure provides a wireless charging system and a control method thereof. The control method includes: when the battery pack is in over-discharged state, controlling the power transmitting module to wirelessly transmit first preset power, i.e., auxiliary electrical energy, to the power receiving module; when the power receiving module receives auxiliary electrical energy, controlling the transmitter wireless communication module to establish wireless communication with the receiver wireless communication module; after wireless communication is established, controlling the power transmitting module to wirelessly transmit first charge signal to the power receiving module enabling the power receiving module charges the battery pack at a first preset current; and after the battery pack recovers to normal charging state, controlling the power transmitting module to wirelessly transmit second charge signal to the power receiving module enabling the power receiving module charges the battery pack at a second preset current.
