Abstract
A device for controlling a charging voltage, includes: a voltage drop unit configured to drop a voltage by a preset magnitude; a voltage comparison unit configured to compare a charging voltage of a battery with a first reference voltage and to output a path selection signal through an output terminal; a first path configured to connect the battery to a charging power supply; a second path configured to connect the battery to the charging power supply, with the voltage drop unit being interposed between the battery and the charging power supply; and a path selector configured to select one from the first path and the second path according to the path selection signal.
