Disclosed is a battery gauging device during a battery charging, which is capable of gauging the charged capacity during a battery charging in a terminal. The device according to the invention comprises a charger for converting an AC voltage to a DC voltage, and outputting the converted voltage, a battery pack including a battery for charging an electric charge, first switching means for switching on/off the DC voltage, and second switching means switched on/off in accordance with a battery charge enable (BCE) signal so as to temporarily discharge the charged capacity during the battery charging, and a terminal including a battery gauging section for gauging a charged capacity inputted from the battery pack and a microprocessor for outputting the BCE signal to the switching means, and displaying the gauged value on a display section. According to the invention, the DC voltage inputted from the charger to the battery pack is charged in the battery, but is regularly interrupted in the course of the battery charging so as to temporarily discharge the charged capacity, thereby realizing an exact display of the charged capacity on the terminal even during the battery charging.
