Abstract
A battery pack includes: a battery unit in which a plurality of battery modules with a plurality of secondary batteries connected in series to each other is connected in parallel to each other so that output current; and a battery management unit. The battery management unit calculates a first allowable current value of each of the plurality of battery modules and calculates second allowable current values of the other battery modules based on the first allowable current value of one battery module from the plurality of battery modules. The battery management unit calculates a value corresponding to the sum of the first allowable current value used as the reference and the respective second current values as an allowable current value when each of the second allowable current values is equal to or smaller than the first allowable current value of the corresponding battery module.
