Abstract

A wireless charging receiving apparatus includes a wireless charging conversion module, a charging management module, a voltage combination module and at least two wireless charging receiving coils. The at least two wireless charging receiving coils are used to couple with a wireless charging transmitting coil in a wireless charging transmitting apparatus and output alternating-current electromagnetic induction signals to the voltage combination module; the voltage combination module is used to carry out voltage superposition on the alternating-current electromagnetic induction signals output by the at least two wireless charging receiving coils and output superposed alternating-current electrical signals to the wireless charging conversion module; the wireless charging conversion module is used to convert received alternating-current electrical signals into direct-current electrical signals, and output the direct-current electrical signals to the charging management module; and the charging management module is used to charge a battery by means of received direct-current electrical signals.
