Abstract

A system and method of testing charging current of a mobile electronic device sets a charging voltage value and a battery voltage value, and sends a control command to a power supply device to generate the charging voltage and the battery voltage. The system and method further receives a charging current value from a current test device under the charging voltage and the battery voltage. Furthermore, the system and method determine if the charging current value falls in an allowable current range and displays test result on a display device.

Claims

1. A computing system for testing charging current of a mobile electronic device, the system comprising a storage system storing a plurality of programs and a processor that executes one or more operations for the plurality of programs, the programs comprising:

a setting module operable to set a charging voltage value and a battery voltage value for the mobile electronic device;

a sending module operable to send a control command to a power supply device to generate the charging voltage and the battery voltage according to the set charging voltage value and battery voltage value;

a receiving module operable to receive a charging current value of the mobile electronic device from a current test device under the charging voltage and the battery voltage generated by the power supply device;

a determining module operable to determine if the charging current value falls in an allowable current range; and

a displaying module operable to display test success or failure information on a display device according to the determination result.

2. The system of claim 1, wherein the power supply device provides direct-current (DC) power to the current test device.

3. The system of claim 1, wherein the mobile electronic device is selected from the group consisting of a mobile phone, a personal digital assistant (PDA), a handheld game player, and a digital camera.

4. The system of claim 1, wherein displaying module displays test success information on the display device, in response to a determination that the charging current value falls in the allowable current range, and displays test failure information on the display device, in response to a determination that the charging current value does not fall in the allowable current range.

5. A computer-implemented method of testing charging current of a mobile electronic device, the method comprising:

(a) setting a charging voltage value and a battery voltage value for the mobile electronic device;

(b) sending a control command to a power supply device to generate the charging voltage and the battery voltage according to the set charging voltage value and battery voltage value;

(c) receiving a charging current value of the mobile electronic device from a current test device under the charging voltage and the battery voltage generated by the power supply device;
