Abstract

The invention belongs to the field of mobile terminals and provides a charging method, a charging circuit and a mobile terminal. A temperature detecting circuit detects the temperature of a cell and outputs the temperature to a control circuit; the control circuit judges whether the temperature is lower than first temperature, if the temperature is lower than the first temperature, a heating instruction is sent to a heating circuit, and if the temperature is higher than or equal to the first temperature, a quick charging instruction is output to a quick charging circuit; when receiving the heating instruction, the heating circuit heats the cell; when receiving the quick charging instruction, the quick charging circuit charges the cell with a first current through a charging interface. Even if the cell is located in a low-temperature outside environment, the surface temperature of the cell can be ensured through the heating circuit, the cell can be charged in a large-current mode, and the charging time is saved.

Description

technical field [0001] The invention belongs to the field of mobile terminals, and in particular relates to a charging method, a charging circuit and a mobile terminal. Background technique [0002] Mobile terminals, also known as mobile communication terminals, refer to electronic devices that can be used on the move, including mobile phones, notebooks, tablet computers, POS machines, IPADs, and even vehicle-mounted computers. Now the third party has developed a large number of application programs for the mobile terminal, which enriches the functions of the mobile terminal. Mobile terminals with rich functions have gradually become people's carry-on items. [0003] As the frequency of use of the mobile terminal gradually increases, the power stored in the battery cell is limited, so it needs to be charged frequently. Existing mobile terminals usually use a MICRO USB interface (including only a power line and a ground line) to charge the battery cells of the mobile termin...
