Abstract
Disclosed are an apparatus and method of controlling switch units between a battery pack and a load, and a battery pack and a battery management system comprising the same. The apparatus comprises a memory for storing the turn-off number and order of first and second switch units connecting the battery pack with the load according to current ranges; and a control unit for equalizing the turn-off order of the first switch unit and the second switch unit with reference to the turn-off number and order in a current range corresponding to a magnitude level of discharge current of a battery. Accordingly, the present invention reduces the frequency of breakdown or malfunction of the switch units and increases the using period of the switch units.
