Zusammenfassung:	Provided is method of calibrating a state of charge (SOC) of a first battery module and a SOC of a second battery module that are serially connected to each other, the method including calculating the SOC of the first battery module, calculating the SOC of the second battery module, and based on the SOC of the first battery module and the SOC of the second battery module, using a direct-current-to-direct-current (DC-to-DC) converter that is electrically connected in parallel with the second battery module to calibrate the SOC of the second battery module by controlling a charge/discharge current between a storage unit and the second battery module, the storage unit being connected in parallel with the second battery module and the DC-to-DC converter.
