Abstract
Embodiments of the present application provide a method and device for identifying a master and slave battery packs. The method includes a first battery pack obtaining, after it is connected to a battery cabinet, its identifier, and obtaining identifiers of other battery packs in the battery cabinet through a communication bus. The total number of the battery packs is N, where N is a positive integer. The method may sort the identifiers of the first battery pack and of the other battery pack to obtain a sorted result. The method may identify the master battery pack and slave battery packs among the first battery pack and the other battery packs according to the sorted result. Each of the battery packs connected to a battery cabinet may automatically identify the master battery pack and slave battery packs according to their identifiers, eliminating manual configuration by a user, and improving configuration efficiency.
