Title: ELECTRONIC DEVICE AND CHARGING CONTROL METHOD THEREFOR
Abstract:
Disclosed by the present application is a charging control method, the method, which is applied to an electronic device, comprising the following steps: determining a resistance value of a charging path impedance circuit of a battery of an electronic device; acquiring a charging current of a constant current charging stage when the battery is in the constant current charging stage; calculating partial voltage of the charging path impedance circuit according to the resistance value of the charging path impedance circuit and the charging current of the constant current charging stage; and adjusting a constant voltage critical voltage, which is for switching a trigger battery from the constant current charging stage to a constant voltage charging stage, to be the sum of an initial constant voltage critical voltage and the partial voltage of the charging path impedance circuit. Also disclosed by the present application is an electronic device. By means of the electronic device and the charging control method of the present invention, the constant current charging stage may be set to be longer within an allowable range, thereby increasing charging speed.
