Abstract
Disclosed is an apparatus and method for estimating a state of charge (SOC) of a battery. The battery SOC estimating apparatus includes a measurement unit configured to measure state information of a battery; a first core unit configured to estimate a first SOC of the battery by applying a first battery modeling technique, based on the state information of the battery measured by the measurement unit; and a second core unit configured to estimate a second SOC of the battery by applying a second battery modeling technique different from the first battery modeling technique, based on the state information of the battery measured by the measurement unit, wherein the second core unit transmits the estimated second SOC to the first core unit, and wherein the first core unit estimates the first SOC of the battery by reflecting the second SOC transmitted by the second core unit.
