Abstract

The invention discloses a wireless charging method, electronic equipment and a charging system. In the method, first electronic equipment transmits a first wireless charging signal to second electronic equipment with a charging frequency as a first frequency and an output voltage as a first voltage. And when the second electronic equipment instructs the first electronic equipment to increase the transmitting power, the first electronic equipment reduces the charging frequency to increase the transmitting power. When the charging frequency is adjusted to the minimum value and the second electronic equipment still indicates the first electronic equipment to increase the transmitting power, the first electronic equipment increases the output voltage so as to increase the transmitting power. By implementing the technical scheme, the flexibility of adjusting the wireless charging power is improved.

Description

technical field [0001] The present application relates to the field of electronic technologies, and in particular, to a wireless charging method, an electronic device, and a charging system. Background technique [0002] In recent years, wireless charging technology (wireless charge technology) has been widely used in electronic devices. The wireless charging technology can be applied to scenarios where the charging base charges electronic devices, and can also be used in scenarios where wireless charging devices such as mobile phones charge other electronic devices in reverse. In the reverse charging scenario, a wireless charging device such as a mobile phone can wirelessly transmit the power in its own battery to a wireless powered device such as a Bluetooth headset. [0003] Currently, most wireless charging technologies utilize electromagnetic induction for power transfer. During wireless charging, the wireless charging device converts the electrical energy in its own ...
