A wireless charging system according to the present invention includes: a first power receiving device connected in parallel with a first battery and including a first sub-resonance circuit having a first resonance frequency; a second power receiving device connected in parallel with the second battery and including a second sub-resonance circuit having a second resonance frequency; and a power transmission device. The power transmission device is configured to determine a charging sequence between the first battery and the second battery. If the first battery is selected according to the charging order, the power transmission device wirelessly transmits first AC power having a first resonant frequency to the first sub-resonant circuit. If the second battery is selected according to the charging order, the power transmission device wirelessly transmits second AC power having a second resonant frequency to the second resonant circuit.
根据本发明的无线充电系统包括:第一电力接收装置,其与第一电池并联连接并且包括具有第一谐振频率的第一子谐振电路;第二电力接收装置,其与第二电池并联连接并且包括具有第二谐振频率的第二子谐振电路;以及电力发送装置。电力发送装置被配置为确定第一电池和第二电池之间的充电顺序。如果根据充电顺序选择第一电池,则电力发送装置将具有第一谐振频率的第一交流电力无线地发送到第一子谐振电路。如果根据充电顺序选择第二电池,则电力发送装置将具有第二谐振频率的第二交流电力无线地发送到第二谐振电路。
