Abstract

The invention relates to the field of mobile terminals, in particular to a charging circuit, a battery core and a mobile terminal. The charging circuit comprises a heating circuit. The heating circuit is electrically connected with a heating film when the battery core and a battery core tank are in the clamping state. The heating film is arranged in the surface layer of the battery core or attached to the surface layer of the battery core in a preset state. The heating film is used for converting electric energy output by the heating circuit into heat energy and heating the battery core through the heat energy. When the battery core is charged in a low-temperature charging environment, the heating film converts the electric energy output by the heating circuit into the heat energy and heats the battery core through the heat energy, so that the temperature of the battery core is guaranteed, and normal charging of the battery core is achieved.

Description

technical field [0001] The invention relates to the field of mobile terminals, in particular to a charging circuit, a battery cell 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. 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. [0003] The batteries used in current mobile phones and most mobile terminals are lithium batteries. Lithium batteries can work in the temperature range of -10 to 55 degrees Cels...
