Abstract

The invention discloses a current control method for a mobile terminal. The current control method for the mobile terminal comprises the following steps: the temperature of the mobile terminal is monitored at preset time intervals; when the temperature of the mobile terminal is detected to be higher than a target temperature, a current reduction value is calculated according to a preset algorithm, and the present charging current is adjusted according to the current reduction value; when the temperature of the mobile terminal is detected to be lower than a differential value between the target temperature and the temperature at a preset interval, the present charging current is adjusted according to a preset current value. The invention further discloses a current control device for the mobile terminal. The balance between the charging current and heat of the mobile terminal can be effectively controlled.

Description

technical field [0001] The present invention relates to the technical field of current control, in particular to a mobile terminal current control device and method. Background technique [0002] With the rapid development of mobile Internet technology, mobile terminals have entered the era of intelligence. Mobile terminals have more and more functions, and the power of mobile terminals is limited. Frequent use of mobile terminals will inevitably lead to frequent charging of mobile terminals. [0003] At present, with the popularization of fast charging technology for mobile terminals, the charging current of mobile terminals can reach 3A or even higher charging current with the support of fast charging. There are trade-offs, fast charging speed often causes serious heat generation of mobile terminals, which will affect user experience. In the prior art, different currents are set according to the temperature range to control the charging current, but the effect of temperat...
