In the present invention, a battery pack type discriminating or deciding concave portion ( 131 ) is formed at a position corresponding to a battery pack type deciding switch ( 214 ) of an SQ battery pack ( 1 ) and when the SQ battery pack ( 1 ) is set, the battery pack type deciding switch ( 214 ) is avoided to be pressed by a bottom ( 115 ) of the SQ battery pack ( 1 ) owing to the concave portion ( 131 ). In this way, as the switch ( 214 ) is avoided to be pressed, it is recognized that the set battery pack is an SQ battery pack ( 1 ) under charging. Therefore, according to the present invention, it is possible to identify battery packs among different charging modes and charging can be performed in a proper charging mode.
