Abstract

Provided are a wireless charging control method, a charging control device and a device to-be-charged. The method includes: according to an output voltage of a wireless receiving circuit, determining whether a power of a wireless charging signal received by the wireless receiving circuit can meet a charging power currently required by a battery; and when the power of the wireless charging signal fails to meet the charging power currently required by the battery, reducing the charging power currently required by the battery. In the embodiments, the output voltage of the wireless receiving circuit serves as the basis for determining whether the power of the wireless charging signal can meet the charging power currently required by the battery; and the difference between the charging power received by and required by the battery is decreased by reducing the charging power currently required by the battery.
