Abstract

A battery comprises a number n of battery module strings, wherein n is a natural number greater than or equal to two. The battery module strings have several battery modules, and one battery module has a coupling unit. The coupling unit is configured as a voltage transformer and couples the battery modules to each other. A method of controlling the battery includes supplying a load connected to the battery with a predefined and substantially constant total power. The total power corresponds to a sum of n individual powers of the n battery module strings. The method further includes setting n−1 string voltages, which are each present at the n−1 battery module strings, according to the total power, the load, and by defining a string voltage present at an nth battery module string with amplitude and phase position. At least two of the n individual powers are asymmetrical to each other.
