Abstract

A system and method of controlling charging process of an electronic device. The electronic device is installed with a battery and a protection circuit. The method includes setting a time interval to check a charging state of the electronic device, checking whether the battery is in an error state before a power supply charges the electronic device, and checking whether the electronic device is in an charging error state according to the time interval till the electronic device completes the charging process. When there is an abnormity, the method can output a message to a user and end the charging process using the protection circuit.

Claims (29)

1. A method of controlling charging process of an electronic device installed with a battery, the method comprising:

providing a protection circuit installed in the electronic device;

setting a time interval to check a charging state of the electronic device;

electronically connecting the electronic device to a power supply;

checking whether the battery is in an error state before the power supply charges the electronic device, wherein the error state is selected from the group consisting of an error identification of the battery, an abnormal working temperature of the battery, an abnormal electronic current of the battery, an abnormal voltage of the battery, and abnormal electrodes of the battery;

cutting off the connection between the electronic device and the power supply by utilizing the protection circuit, and outputting a message to a user if the battery is in the error state, or controlling the power supply to continue charging the electronic device if the battery is not in the error state;

checking whether the electronic device is in a charging error state according to the time interval before the electronic device completes the charging process; and

responding to the electronic device being in the charging error state, and outputting a message to the user and ending the charging process using the protection circuit.

2. The method as described in claim 1 , wherein the charging error state is selected from the group consisting of a working temperature of the battery is abnormal, a charging current of the battery is abnormal, and a charging voltage of the battery is abnormal.

3. The method as described in claim 1 , wherein the electronic device is one of a mobile phone, a personal digital assistant, a personal computer, and a game machine.

4. A storage medium having stored thereon instructions that, when executed by a processor of an electronic device, causes the processor to perform a method for controlling charging process of the electronic device installed with a battery, the method comprising:

providing a protection circuit installed in the electronic device;

setting a time interval to check a charging state of the electronic device;

electronically connecting the electronic device to a power supply;

checking whether the battery is in an error state before the power supply charges the electronic device, wherein the error state is selected from the group consisting of an error identification of the battery, an abnormal working temperature of the battery, an abnormal electronic current of the battery, an abnormal voltage of the battery, and abnormal electrodes of the battery;

cutting off the connection between the electronic device and the power supply by utilizing the protection circuit, and outputting a message to a user if the battery is in the error state, or controlling the power supply to continue charging the electronic device if the battery is not in the error state;

checking whether the electronic device is in a charging error state according to the time interval before the electronic device completes the charging process; and

responding to the electronic device being in the charging error state, and outputting a message to the user and ending the charging process using the protection circuit.

5. The storage medium as described in claim 4 , wherein the charging error state is selected from the group consisting of a working temperature of the battery is abnormal, a charging current of the battery is abnormal, and a charging voltage of the battery is abnormal.

6. The storage medium as described in claim 4 , wherein the electronic device is one of a mobile phone, a personal digital assistant, a personal computer, and a game machine.

7. A system for controlling charging process of an electronic device installed with a battery, the electronic device connecting a power supply, the system comprising:

a protection circuit installed in the electronic device;

a setting module operable to set a time interval to check a charging state of the electronic device;

a checking module operable to check whether the battery is in an error state before the power supply charges the electronic device, and check whether the electronic device is in a charging error state according to the time interval before the electronic device completes the charging process, wherein the error state is selected from the group consisting of an error identification of the battery, an abnormal working temperature of the battery, an abnormal electronic current of the battery, an abnormal voltage of the battery, and abnormal electrodes of the battery;

a processing module operable to cut off the connection between the electronic device and the power supply using the protection circuit if the battery is in the error state, and end the charging process if the electronic device is in the charging error state, or control the power supply to continue charging the electronic device if the electronic device is not in the charging error state;

a reporting module operable to output a message indicating that the battery is in the error state or the electronic device is in the charging error state; and

at least one processor that executes the setting module, the checking module, the processing module, and the reporting module.

8. The system as described in claim 7 , wherein the charging error state is selected from the group consisting of a working temperature of the battery is abnormal, a charging current of the battery is abnormal, and a charging voltage of the battery is abnormal.

9. The system as described in claim 8 , wherein the electronic device is one of a mobile phone, a personal digital assistant, a personal computer, and a game machine.
