Abstract
A battery pack includes a battery module including battery cells, a current measurement module measuring a charge current supplied to the battery module, and a processor. Upon detecting connection of a charger to the battery pack, the processor sets a sinusoidal waveform charge current frequency supplied from the charger to the battery module as first frequency, recognizes the charge current frequency based on a charge current value measured through a current measurement module according to a first number of sampling times for one cycle set to the first frequency, and adjusts the number of sampling times for one cycle based on the recognized frequency of the charge current. A corresponding charge current measuring method of measuring a charge current and a charge current measurement systems are also provided.
