    摘要： Disclosed is a battery system including a plurality of battery packs; and a battery control device configured to collect voltage values for each of the plurality of battery packs and to control charging of the plurality of battery packs, based on the collected voltage values. The battery control device may be configured to determine a charging group by selecting one or more battery packs having a voltage value within a predefined threshold range, and to control the battery packs included in the charging group to be charged together up to a predefined target voltage. Here, the battery control device may be configured, when charging up to the target voltage is completed, to update the charging group by selecting, among battery packs in which charging is not in progress, a battery pack whose voltage value is within a predefined threshold range from a voltage value of the charging group.
