An energy storage device. An energy supply branch, with a plurality of energy storage modules is connected in series via first module connections along a first energy supply line and via second module connections along a second energy supply line. The energy storage modules include an energy storage cell module having an energy storage cell, a first coupling device having first coupling elements, configured to switch or bypass the energy storage cell module selectively between the first module connections, and a second coupling device having second coupling elements, which are designed to switch or bypass the energy storage cell module selectively between the second module connections. The energy storage device also includes an output connection coupled to an output of the first energy supply line; and two additional connections coupled to the outputs of the second energy supply line.
