A battery pack including: a battery including a battery cell; a temperature sensor for detecting a temperature of the battery; a cell voltage measuring unit for measuring a cell voltage of the battery cell and generating cell voltage data including a cell voltage value; a temperature measuring unit coupled to the temperature sensor, the temperature measuring unit being for generating temperature data including a temperature value corresponding to the temperature of the battery detected by the temperature sensor; and a control unit for determining a maximum charging current value (MCCV) of a charging current for charging the battery based on the cell voltage data and the temperature data. The control unit is for transmitting the MCCV to a charging apparatus for supplying the charging current to the battery pack. The charging apparatus is for controlling the charging current supplied to the battery pack to have a value below the MCCV.
