Abstract

A method is used for controlling a battery having at least one battery module line with a plurality of battery modules that are connected in series. Each battery module has at least one battery cell, at least one coupling unit, a first connection, and a second connection. Each battery module is configured to assume one of at least two switching states dependent on a control of the coupling unit. The different switching states correspond to different voltage values between the first connection and the second connection of the battery module. The method includes determining a ranking among the battery modules. The method also includes engaging the battery modules in a supply of a desired output voltage of the battery module line using the ranking. The battery modules compare respective battery module operating states among one another and determine the ranking on the basis of the comparison.
