主权项

1. A charging apparatus using a pad type electrode contact point, the charging apparatus comprising:
a charging plate having a plate shape, including first and second contact point electrodes having polarities and formed to be exposed and a third contact point electrode not having a polarity and formed to be exposed, and receiving power from an adaptor when a charging voltage of a battery is sensed through the first contact point electrode, thereby providing the power through the second and third contact point electrodes; and an attaching plate installed on a portable terminal, including fourth and fifth contact point electrodes having shapes corresponding to those of the first and second contact point electrodes, polarities opposite to those of the first and second contact point electrodes, and formed to be exposed and a sixth contact point electrode having a shape corresponding to the third contact point electrode and formed to be exposed, sensing a remaining voltage of the battery to provide the remaining voltage to the first contact point electrode through the fourth contact point electrode, and receiving power provided from the second and third contact point electrodes through the fourth and sixth contact point electrodes to provide the power to a charging circuit of the portable terminal.
