The present invention relates to a non-contact type battery pack charging
apparatus using a magnetic field. In the non-contact type battery pack
charging apparatus of the present invention, a main control unit (120)
receives input data from a voltage comparison unit (140), a current
comparison unit (150), a voltage detection unit (170) and a current
detection unit (180), determines whether required conditions are
fulfilled, such as whether an object is installed, whether the installed
object is a battery pack (200), what the charge capacity of the battery
pack (200) is, and whether the charging of the battery pack (200) has
been completed, and controls a variable-voltage frequency generation unit
(130) to be operated so as to correspond to the required conditions.
Accordingly, the charging of the battery pack (200) is performed to
correspond to the charging capacity of the battery pack (200) only when
the battery pack (200) is installed.
