Abstract

An embodiment of the invention provides terminal equipment, a power adapter and a charging control method. The Terminal equipment provided by the embodiment of the invention comprises a system chip, a charging chip, a first charging interface, a first switch, a first charging control chip and a first blocking coupling circuit, wherein the first charging control chip can control the first switch when the terminal equipment is being charged rapidly, a positive data pin of the first charging interface is connected with a power supply pin, a negative data pin of the first charging interface is connected with a grounding pin, thus a data line and a power line in a USB transmission line are both used for charging, thereby increasing a charging current, reducing a voltage difference between an input end and an output end of the charging chip of the terminal equipment when the charging power is constant, further reducing loss of the charging chip, reducing the heating degree of the terminal equipment when in charging, improving the charging efficiency, and solving the problems of severe heating of the terminal equipment and low charging efficiency caused by great loss of the terminal equipment during the rapid charging process in the prior art to some extent.

Description

【Technical field】 [0001] The present invention relates to the communication field, in particular to a terminal device, a power adapter and a charging control method. 【Background technique】 [0002] As the terminal equipment has more and more functions, correspondingly, the power consumption of the terminal equipment is also increasing. This results in frequent charging of the terminal equipment. This demand has promoted the generation of fast charging technology. [0003] Among them, a fast charging solution uses a charging chip to charge a battery of a terminal device. figure 1 It is a schematic structural diagram of a terminal device in the prior art. like figure 1 shown. In the prior art, a terminal device includes a system chip 11 , a charging chip 12 and a charging interface 13 . The charging interface 13 is connected to the charging chip 12 through a power line on the one hand, and connected to the system chip 11 through a data line on the other hand. [0004] i...
