Hereinafter, the technical means shown in the present application will be described in detail by specific examples. It should be noted that the following embodiments may exist alone or in combination with each other, and the description of the same or similar contents is not repeated in different embodiments.

First embodiment

The power adapter also includes a pair of communication ports, a first port D + which may be a positive communication port D + and a second port D-which may be a negative communication port.

Referring to fig. 4, the charging chip may include a current generating module. The current generation module is respectively connected with the data transmission interface and the power adapter, and is used for providing target current for the data transmission interface so that the power adapter can adjust output voltage according to the target current.

Optionally, the current generating module is connected to the first port D + and the second port D-of the data transmission interface, the first port D + and the second port D-of the data transmission interface may be used to identify a fast charging protocol, and after the fast charging protocol is identified, the current generating module provides a target current to the data transmission interface, where the target current may be a differential current between the first port D + and the second port D-of the data transmission module. The target current can sequentially flow through the first port D + of the power adapter, the second port D-of the power adapter and the other end of the current generation module from one end of the current generation module, so that a loop is formed, and the power adapter can adjust the output voltage according to the target current to realize rapid charging protocol handshake.

Optionally, when the intelligent terminal needs to be charged, after the intelligent terminal is electrically connected with the power adapter, the fast charging protocol is identified through the first port D + and the second port D-of the data transmission interface, after the fast charging protocol is identified, the current generation module provides a target current for the data transmission interface, the power adapter adjusts the output voltage according to the size of the target current by detecting the size of the target current, so that the power adapter can charge the charging chip, and the handshake of the fast charging protocol between the intelligent terminal and the power adapter is realized.

Alternatively, the target current provided by the current generation module may be a required charging current or have a corresponding relationship with the charging current. For example, the charging current required for fast charging of a mobile phone is generally 2A, and if the fast charging is to be implemented, the target current generated by the current generation module may be adjusted to be 2A, or the target current generated by the current generation module may be adjusted to be a value having a corresponding relationship with 2A.
