A display device of a battery charging state using sense resistor is provided to indicate the charged state of battery such that a user can check the progress in charge at a glance easily. The display device of a battery charging state includes a sense resistor(R) for sensing a current flowing therethrough when a DC voltage is input; a charging part(120) for converting an input current(Iin) and an input voltage(Vin) into a charge current(Iout) and a charge voltage(Vout) to be output; a battery(130) for charging the charge current(Iout) and the charge voltage(Vout); a main control part(140) for calculating the charge current(Iout), determining a charging state therefrom and outputting a control signal indicating the charging state; and a display part(150) for displaying the charging state by the control signal. |
