Abstract

A method of controlling state of charge (SOC) of a first battery and a second battery that are connected in parallel with each other, includes: calculating the SOC of the first battery and the SOC of the second battery; controlling output voltage command values of a first direct current (DC-DC) converter and a second DC-DC converter based on the SOC of the first battery and the SOC of the second battery, the first DC-DC converter and the second DC-DC converter being connected to ends of the first battery and the second battery, respectively; and controlling the SOC of the first battery and the SOC of the second battery based on the controlling of the output voltage command values of the first DC-DC converter and the second DC-DC converter.
