Provided is a charging protection circuit. The charging protection circuit includes a wireless charging base and a charging receiving circuit. The charging receiving circuit includes first receiving coils configured to receive electromagnetic waves from the wireless charging base; a high-permeability magnetic core coupled to the first receiving coils and configured to block electromagnetic waves opposite to the electromagnetic waves from the wireless charging base; a detection circuit coupled to the high-permeability magnetic core and configured to detect whether the high-permeability magnetic core has failed; and a power supply circuit coupled to the high-permeability magnetic core and configured to convert electromagnetic energy generated by electromagnetic waves into electric energy to supply power to a power receiving device. With the technical solution, the serious result caused by continuous charging of a wireless charger after a high-permeability magnetic core has failed is avoided, thus guaranteeing the security of a power receiving device.
