Abstract: The present invention relates to a battery charging device and a charging control method thereof, the battery charging device including: a charger configured to provide a charging voltage for charging a battery; at least one processor configured to control the charger; and a variable resistor placed on a charging path and configured to adjust a charging capacity provided from the charger to the battery and have a resistance determined corresponding to a digital code received from the processor, wherein the processor corrects the digital code to be output to the variable resistor in accordance with battery charging characteristics monitored during a charging cycle of the battery. Thus, flexible and adaptive charging control is possible through at least one digital variable resistor provided in the charging device, and error situations are handled in real time by correcting the digital code through monitoring in a charging process.
