Abstract: Embodiments provide focused wireless charging method and apparatus based on radio frequency receiving and phase compensation retransmission. The method is based on the reciprocity principle, making each charging signal transmitted by the external charging system could stack in-phase when arriving at the embedded rechargeable battery, realizing wireless near field focusing in any given area in an unknown complex inhomogeneous propagation environment and a high charging efficiency. The focused wireless charging technology based on radio frequency receiving and phase compensation retransmission in embodiments could realize in-phase stacking and precise focus of each wireless charging signal of the external system on the embedded batteries to be charged automatically under different propagation environment, different environment medium, and possible random offset of the rechargeable battery.
