Abstract

The present invention discloses a charging current control method and device, wherein the method includes: during the process of fast charging the battery of a terminal device with a first current value, acquiring the temperature value of the battery, and the The main board temperature value of the terminal device, wherein the main board temperature value can represent the overall temperature value of the terminal device; judge whether the temperature value of the battery is within the fast charging safe temperature range; if so, based on the main board temperature value, adjusting the first current value for charging the battery to a second current value smaller than the first current value, and charging the battery with the second current value. It is used to solve the technical problem that the existing battery charging scheme for the terminal cannot guarantee the safety of battery charging while reducing the temperature of the device.

Description

technical field [0001] The invention relates to the technical field of charging, in particular to a method and device for controlling charging current. Background technique [0002] The existing fast charging for the battery of the terminal equipment can easily cause the temperature of the terminal equipment to be too high. Especially in the process of playing while charging, the temperature rise (ie temperature rise) of the device is particularly prominent. To this end, once the battery temperature exceeds a preset threshold during charging, the charging current is reduced, thereby reducing the temperature rise. [0003] However, before the temperature of the device is lowered, the battery is still at a higher temperature and continues to be charged, which is very easy to damage the battery, lower the battery cell phone, or even explode. [0004] It can be seen that the existing solution for charging the battery of the terminal device cannot guarantee the safety of batter...
