A fast charging method, charger and terminal

Abstract

The invention discloses a charger and a terminal. The charger includes: an output control circuit, the output control circuit includes a charging interface, an interface detection unit and a control unit, wherein: the charging interface is used to connect with the charging slot of the terminal, It includes N sub-interfaces, each sub-interface includes a charging integrated circuit, and each sub-interface is respectively connected to the corresponding sub-slot in the charging slot, N≥2; the interface detection unit is used to detect whether the charging interface and the charging slot of the terminal The connection is successful; the control unit is used to control each charging integrated circuit to charge the battery unit corresponding to the sub-slot respectively if the charging interface is successfully connected to the charging slot. Correspondingly, the invention also discloses a fast charging method. By adopting the embodiment of the present invention, by increasing the limit charging current and parallel charging, the charging speed can be improved, the time for the user to wait for charging can be shortened, and user experience can be enhanced.

Description

technical field [0001] The invention relates to the field of batteries, in particular to a fast charging method, a charger and a terminal. Background technique [0002] Mobile devices (such as mobile phones, PADs, etc.) have become an indispensable part of people's entertainment life, especially in some public places, such as airports, coffee shops, shopping malls or train stations, etc. People especially like to use mobile devices while waiting To kill time, and with the increase of the functions of mobile devices and the application of various energy-consuming software, the power consumption is getting faster and faster. Therefore, there is an urgent need for a fast charging method that can complete the charging needs in a short time . [0003] The essence of the so-called fast charging is to shorten the charging time of the battery by increasing the charging current in the constant current charging phase of the battery. At present, the charging integrated circuit (full ...

AI Technical Summary

Problems solved by technology

At present, the charging integrated circuit (full name: Integrated Circuit, abbreviation: IC) is built on the printed circuit board (full name: Printed Circuit Board, abbreviation: PCB) of the terminal equipment. Since the internal space of the terminal equipment is very limited, the charging integration The wires in the circuit are very thin, which limits the limit charging current physically, that is, the maximum charging current it can withstand is small, so that only a small charging current can be used for charging, and the charging requirement cannot be completed in a short time
