Abstract

The present invention provides a communication method, a terminal device and a power adapter. The communication method includes: modulating a pre-configured digital signal into a charging current of a charging signal; demodulating an output voltage of the charging signal to obtain a response signal, and The response signal is used to indicate that the power adapter has received the digital signal. In this way, the power adapter can communicate with the power adapter without the fast charging communication control circuit terminal equipment, thereby reducing the components of the power adapter and reducing the cost of the power adapter.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a communication method, terminal equipment and a power adapter. Background technique [0002] With the rapid development of terminal technology, terminal equipment has become an indispensable tool in people's life, and brings great convenience to all aspects of users' life. Generally speaking, most terminal devices are equipped with matching power adapters. During the communication process between the terminal device and the power adapter, the communication request initiated by the terminal device needs to pass through the fast charging communication control circuit of the power adapter before it can be obtained by the power adapter, resulting in more components and higher costs for the power adapter. Contents of the invention [0003] Embodiments of the present invention provide a communication method, a terminal device, and a power adapter to solve the problem ...
