Abstract

An electronic device includes: a secondary battery; a terminal, which receives electric power to charge the secondary battery; a switch, which turns on and off a connection between the secondary battery and the terminal; and a controller, which controls the switch to be turned off for a predetermined period at a time of starting to charge the secondary battery.

Claims

1. An electronic device comprising:

a secondary battery;

a terminal, which receives electric power to charge the secondary battery;

a switch, which turns on and off a connection between the secondary battery and the terminal; and

a controller, which controls the first switch to be turned off for a predetermined period at a time of starting to charge the secondary battery.

2. A charging apparatus comprising:

a terminal, which is used to supply electric power to a secondary battery;

a detector, which detects a current flowing to the terminal;

a switch, which turns on and off a connection between the secondary battery and the terminal; and

a controller, which controls the switch to be turned off if the detector detects a current for a predetermined period at a time of starting to charge the secondary battery.

3. A non-transitory computer-readable medium having instructions to control electronic device to perform operations comprising:

detecting a start of charging of a secondary battery; and

controlling a switch connected to the secondary battery to be turned off for a predetermined period at a time of starting to charge the secondary battery.

4. A non-transitory computer-readable medium having instructions to control electronic device to perform operations comprising:

detecting a current flowing to a terminal which is used to supply charging power to a secondary battery; and

turning off a switch for a predetermined period at a time of starting to charge the secondary battery if the current is detected in the detecting.

5. A charging method comprising:

detecting a start of charging of a secondary battery; and

controlling a switch connected to the secondary battery to be turned off for a predetermined period at a time of starting to charge the secondary battery.

6. A charging method comprising:

detecting a current flowing to a terminal which is used to supply charging power to a secondary battery; and

turning off a switch for a predetermined period at a time of starting to charge the secondary battery when the current is detected in detecting.
