Abstract

The invention provides a battery heating circuit, a battery heating method and apparatus, and a terminal. A circuit comprises a switch device, a switch control circuit connected with the switch device, and a heating assembly connected with the switch device, wherein the switch control circuit is used for controlling the switch device to a closed state if the temperature value of a battery is detected to be lower than a first threshold during charging of the battery; and the heating assembly is used for heating the battery only when the switch device is in the closed state. According to the invention, when the battery is in a low temperature environment, the battery can be automatically heated to avoid the problem that a charging speed becomes slow due to too low battery temperature, so thecharging speed of the terminal in a low temperature environment is improved.

Description

technical field [0001] The present disclosure relates to the communication field, and in particular to a battery heating circuit, a battery heating method and device, and a terminal. Background technique [0002] In related technologies, the charging performance of the battery is limited by temperature, especially at low temperature, the charging capacity of the battery is reduced, the charging current needs to be limited to a small rate, the charging resistance becomes larger, and the charging speed is very slow. If the temperature drops below zero, it will even stop charging, seriously affecting the battery heating speed, and the user experience is not good. Contents of the invention [0003] In view of this, the present disclosure provides a battery heating circuit, a battery heating method and device, and a terminal to solve the deficiencies in related technologies. [0004] According to a first aspect of an embodiment of the present disclosure, there is provided a ba...
