Problems solved by technology

With the increasing power consumption of current terminals and the increasing capacity of their batteries, traditional chargers are faced with problems such as low charging efficiency and long time-consuming. In order to solve the problem of slow charging, a fast charger has been introduced. charger
[0003] However, the current charger can only rely on the short circuit between DP and DM to identify the ordinary wall charging mode and perform ordinary charging on the terminal, but cannot recognize the fast charging request and cannot perform fast charging on the terminal

Abstract

The invention provides a terminal, a charger and a charging method. The terminal comprises a request unit and a transmitting and receiving unit. The request unit sends a fast charging request to the charger according to a fast charging protocol when the charger charges the terminal in an ordinary way through a charging line in a universal serial bus. The transmitting and receiving unit receives a fast charging request response from the charger and sends a fast charging control command to the charger to control the charger to fast charge the terminal through the charging line. By adopting the technical scheme of the invention, the charging method can be compatible with a traditional means of charger identification, fast terminal charging by the charger is realized, and the problem of slow charging is solved.

Description

technical field [0001] The present invention relates to the technical field of terminals, in particular, to a terminal, a charger and a charging method. Background technique [0002] Current mobile devices (such as mobile phones) and other terminals mainly rely on the connection status of DP (Digital Positive) and DM (Digital Mimus) at the charger end to identify the charger, such as figure 1 As shown, when the charger terminals DP and DM are short-circuited, the terminal can identify the type of the charger through the charger terminals DP and DM, such as DCP (standard wall charging), and start charging through the serial bus VBUS. With the increasing power consumption of current terminals and the increasing capacity of their batteries, traditional chargers are faced with problems such as low charging efficiency and long time-consuming. In order to solve the problem of slow charging, a fast charger has been introduced. charger. [0003] However, the current chargers can o...
