Abstract

The embodiment of the invention provides a terminal and a charging method thereof. The charging method comprises the steps of obtaining battery voltage of the terminal in real time when detecting that charging equipment is connected to the terminal; and adjusting the charging voltage of the charging equipment according to the battery voltage, and controlling a first voltage conversion chip and a second voltage conversion chip to execute voltage conversion operation corresponding to the charging voltage to charge the battery. The charging voltage is converted by arranging two voltage conversion chips, so that the temperature generated by each voltage conversion chip in the voltage conversion process is reduced; and charging voltage and current of the battery are adjusted according to the charging voltage, so that high-efficiency fast charging of the battery is achieved.

Description

technical field [0001] The invention relates to the technical field of charging, in particular to a terminal and a charging method. Background technique [0002] With the progress of the times, the Internet and mobile communication networks provide a large number of functional applications. Users can not only use the terminal for traditional applications, such as: answer or make calls with a smart phone; at the same time, users can also use the smart phone to browse web pages, transfer pictures, and play games. As the frequency of use of the terminal increases, the terminal needs to be charged frequently. [0003] In the existing terminal, there is a charging chip inside. After the charging adapter is connected to the electronic device, the charging chip is used to charge the battery of the terminal. If the charging chip is used to charge the battery at high voltage, it will Charging causes the local temperature of the charging chip to rise and the charging loss is large. ...
