Abstract
Battery state of charge (SOC) determination apparatuses and methods are disclosed, where the battery SOC determination apparatus includes a grouper configured to cluster the cells in the battery pack into the groups based on similarity of the sensing data among the cells, a representative cell selector configured to select the representative cell for the each group, a first SOC estimator configured to estimate the SOC of the representative cell of the each group based on the battery model, and a second SOC estimator configured to determine the SOC of the battery pack based on the SOC of the representative cell of the each group.
