Abstract

The invention provides a charging method and device adaptive to chargers with different power. The method comprises the steps as follows: one charger is controlled to charge a battery of a mobile terminal according to charge current I<N>, N is a positive integer, an initial value of the N is 1 and the charge current I<1> is preset minimum charge current; stable output voltage V<N> output by the charger during charging according to the charge current I<N> is read; if the output voltage V<N> is greater than preset safe voltage, the charge current I<N> is added to a preset first current value to obtain the charge current I<N+1> and N=N+1; the step of controlling the charger to charge the battery of the mobile terminal according to the charge current I<N> is executed; and if the output voltage V<N> is smaller than or equal to the preset safe voltage, the optimal charge current is determined according to the charge current I<N> and the charger is controlled to charge the battery according to the optimal charge current. By the method and the device, adjustment on the charge current can be effectively achieved and the damage due to the fact that the chargers with different charge power charge the mobile terminal is avoided.

Description

technical field [0001] The invention relates to the field of equipment charging, in particular to a charging method and device for adapting chargers with different powers. Background technique [0002] With the development of science and technology, mobile terminals such as mobile phones, PAD (Personal Digital Assistant, Pocket Computer), and tablet computers have become popular among various people as popular electronic products. An essential accessory for the terminal. [0003] Among the existing chargers for charging mobile terminals, there are many chargers with different powers (such as 5V / 1A, 5V / 2A, etc.). Although the charging power is different, the interface of these chargers for charging mobile terminals They are all consistent, so the user may use other chargers whose charging power is inconsistent with the standard charger of the mobile terminal to charge the mobile terminal. However, if the charging power of the charger used by the user is greater than the cha...
