Charging method and charging device

Abstract

The invention discloses a charging method and a charging device. The method comprises the following steps: obtaining the temperature T of a battery; setting the maximum temperature Ts to be equal to a second critical temperature Tm when the temperature T is smaller than or equal to a first critical temperature Tn; judging whether a terminal is at a using condition when the temperature T is greater than the first critical temperature Tn; setting the maximum temperature Ts to be equal to the first critical temperature Tn when the terminal is at the using condition; setting the maximum temperature Ts to be equal to the second critical temperature Tm when the terminal is not at the using condition; reducing the charging current when T is greater than Ts; and increasing the charging current when T is smaller than Ts-K, wherein Tn is smaller than Tm, and K is a preset constant. Thus, the charging current is correspondingly controlled according to battery problems and using conditions when the terminal is charged, the charging current is appropriately increased when the terminal is not used by a user so as to improve the charging speed, and the charging current is appropriately reduced when the terminal is used by the user so as to prevent the terminal from being overheated to influence the using comfort of the user, so that the charging speed and the comfort degree of the user using the terminal are both taken into account.

Description

technical field [0001] The invention relates to the technical field of charging, in particular to a charging method and a charging device. Background technique [0002] When the mobile terminal is charging, if the charging current is increased, the charging speed will be accelerated, but at the same time the battery temperature will be raised; if the charging current is reduced, the battery temperature will be lowered, but the charging speed will also be reduced. Therefore, in the prior art, the charging current is directly adjusted by detecting the battery temperature, which can not only prevent the terminal from overheating but also ensure a normal charging speed. [0003] However, many users have the habit of using the mobile terminal while charging. In this case, both battery charging and terminal power consumption will cause the temperature of the terminal to rise. At this time, if the charging current is simply reduced according to the battery temperature, the normal ...

Problems solved by technology

[0003] However, many users have the habit of using mobile terminals while charging. In this case, battery charging and terminal power consumption will cause the temperature of the terminal to rise.

At this time, if the charging current is simply reduced according to the battery temperature, the normal charging speed will be affected; if the charging current is not adjusted, it will cause the terminal to overheat and affect the comfort of the user when using the terminal

Therefore, the existing technical solutions are difficult to balance the charging speed and the comfort of using the terminal during the charging process.
