Method and apparatus for controlling power supply

DETAILED DESCRIPTION The object of the present invention is to provide a method and apparatus for controlling power supply.
According to one aspect of the present invention, there is provided a power supply controlling apparatus comprising: a battery being chargeable, supply means for supplying a charge current to the battery, and control means for sampling a battery voltage of the battery at predetermined sampling times while the battery is charged, determining in accordance with the sampled battery voltage whether or not the battery is in a full charge state, and for causing the supply means to stop the supply of the charge current to the battery when the battery is in the full charge state.
According to another aspect of the present invention, there is provided a power supply controlling method comprising the steps of determining whether or not a battery is set in the electric apparatus and whether or not an adapter for supplying a charge current to the battery is connected, the battery being chargeable, causing the battery to be charged when the battery is set and the adapter is connected, sampling a battery voltage of the battery at predetermined sampling times when the battery is being charged, determining in accordance with the sampled battery voltage whether or not the battery is in a full charge state, and stopping the supply of the charge current to the battery when the battery is in the full charge state.
Additional objects and advantages of the invention will be set forth in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.
The objects and advantages of the invention may be realized and obtained by means of the instrumentalities and combinations particularly pointed out in the appended claims.
