Abstract

The invention relates to a wireless charging method, a transmitter, a receiver and a power management module. The wireless charging method includes the following steps: when the connection with a charger is detected, the voltage and current source capability information of the charger is acquired; when fast wireless charging authentication information is received from a wireless charging receiver,acknowledgement information corresponding to the fast wireless charging authentication information is determined according to the voltage and current source capability information of the charger; theacknowledgement information is sent to the wireless charging receiver; and when a charging request sent by the wireless charging receiver in response to the confirmation information is received, a voltage and a current corresponding to the charging request are requested from the charger. The wireless charging process is optimized, and the flexibility of wireless charging is improved.

Description

technical field [0001] The present disclosure relates to the technical field of charging, and in particular to a wireless charging method, a transmitting end, a receiving end and a power management module. Background technique [0002] At present, wireless charging technology, especially the wireless charging technology of WPC (Wireless Power Consortium, Wireless Power Consortium), is more and more applied in mobile terminals. For example, wearable smart devices have widely used wireless charging technology, and some smart phones also use WPC wireless charging technology for charging. The USB PD (Universal Serial Bus Power Delivery) protocol is a protocol launched by the USB Association to support higher power charging. At present, USB PD protocol and Type C interface are also increasingly used in mobile terminals, and chargers supporting USB PD are becoming more and more common. [0003] In related technologies, some wireless charging technologies support chargers with DC...
