A battery system has a battery with a plurality of battery modules which can be selectively activated or deactivated by means of actuation, wherein, in the activated state, the battery module voltage of a respective battery module contributes to an output voltage of the battery and, in the deactivated state, the battery module is uncoupled from the current path of the battery. The battery system comprises a circuit for charging the battery modules which has components which are arranged in accordance with a switching converter topology, which is integrated in the battery system in such a way that the battery modules can be charged independently of whether a respective battery module which is to be charged is in the activated or in the deactivated state. A method for charging battery modules, a method for balancing battery modules, and a motor vehicle include the battery system.
