摘要：
A battery depth-of-charge calculation apparatus according to an embodiment disclosed herein includes an information obtaining unit configured to obtain an open circuit voltage (OCV) value with respect to a state of charge (SoC) of a battery cell and information about a voltage value with respect to an SoC of the battery cell during charge, a resistance calculating unit configured to calculate an inner resistance value with respect to the SoC of the battery cell during charge, based on the information about the voltage value with respect to the SoC of the battery cell during charge and the open circuit voltage value with respect to the SoC of the battery cell, and a depth-of-charge calculating unit configured to calculate a negative electrode depth-of-charge of the battery cell based on the inner resistance value.
