ELECTRONIC DEVICE AND METHOD FOR CHARGING ELECTRONIC DEVICE
First Claim
1. An electronic device connected to a power supply equipment, the electronic device comprising:
- a battery;
a universal serial bus (USB) interface;
a storage device;
at least one processor; and
one or more programs being stored in the storage device and executable by the at least one processor, the one or more programs comprising;
a calculation module that sets an initial value of a charging current of the battery and a charging current increment, and gradually increases the charging current value by the charging current increment based on the initial value of the charging current;
a read module that reads an instant charge current passing through the USB interface of the electronic device, and reads an instant value of a voltage across the USB interface of the electronic device;
a determination module that compares a value of the voltage across the USB interface of the electronic device with a preset voltage value, and compares a current value of the charging current with a maximum charging current value of the battery if the value of the voltage across the USB interface of the electronic device is greater than the preset voltage value; and
a processing module that controls the battery charge from the power supply equipment by setting the maximum charging current value as the value of the charging current, if the charging current value is not less than the maximum charging current value.

Abstract
In a method for charging an electronic device, the method increases a charging current value of a battery of the electronic device by a preset charging current increment, and compares a current value of the charging current with a maximum charging current value of the battery if the value of the voltage across a universal serial bus (USB) interface of the electronic device is greater than the preset voltage value. The method controls the battery of the electronic device charge from a power supply equipment by setting the maximum charging current value as the value of the charging current, if the charging current value is not less than the maximum charging current value.
