A battery module line (50) is described, the output (55) of which can be connected to an input of a direct current machine (54). The battery module line (50) comprises a multiplicity of battery modules (51, 52, 53) which are connected in series. Each battery module (51, 52, 53) comprises at least one battery cell (41), at least one coupling unit (30, 70), a first terminal (42) and a second terminal (43) and is designed to assume one of at least two switched states as a function of actuation of the coupling unit (30, 70), wherein various switched states correspond to different voltage values between the first terminal (42) and the second terminal (43) of the battery module (51, 52, 53). |
