The present invention relates to a battery pack charger for improving the charging amount of the battery pack including two or more battery units connected in series. The battery pack comprises: two or more charging units which correspond to and are electrically connected to the battery units, respectively; a sensing unit which is electrically connected to the charging units and measures voltage of the battery units; a control unit which outputs a control signal on the basis of the voltage of the battery units transmitted from the sensing unit; and a power supply unit which applies charging current to the charging units on the basis of the control signal transmitted from the control unit, wherein the control unit controls the charging unit to block the charging current applied to the battery unit reaching a reference voltage among the battery units, to charge all the battery units to the reference voltage. |
