Abstract

The invention relates to a charging device, which is applied to a first terminal and comprises a transceiver, a voltage conversion module and a power supply module. The voltage conversion module at least comprises two kinds of step-up ratio voltage conversion modules, is connected between the transceiver and the power supply module, and is used for boosting the output voltage of the power supply module and then providing the boosted output voltage to the transceiver when the first terminal supplies power in the reverse direction, and reducing the input voltage provided by the transceiver and supplying the voltage to the power supply modulewhen the first terminal charges in the forward direction; and the transceiver is used for radiating a wireless charging signal outwards based on the voltage boosted by the voltage conversion module when the charging device supplies power, and receiving the wireless charging signal, converting the received wireless charging signal into an input voltage and transmitting the input voltage to the voltage conversion module when the charging device charges. The embodiment of the invention further provides a charging method, a terminal and a storage medium.

Description

technical field [0001] The present disclosure relates to the technical field of charging, and in particular to a charging method, device, terminal and storage medium. Background technique [0002] With the development of wireless charging technology, more and more terminals, including many wearable devices and smart terminals, begin to apply wireless charging technology for charging. Wireless charging technologies mainly include WPC as the standard magnetic induction wireless charging technology and A4WP as the standard magnetic resonance technology. At present, there are more and more scenarios where mobile terminals use wireless charging, and many mobile phones support wireless reverse charging technology, such as Samsung, Xiaomi, Huawei, Apple and other mainstream manufacturers, but the reverse charging power supported by existing mobile phones is mostly relatively low . Contents of the invention [0003] The disclosure provides a charging method, device, terminal and...
