Abstract

The invention relates to an energy storage device (2) comprising at least one first energy supply branch (2a, 2b, 2c) which is designed to supply a separately excited electrical machine (1) with energy via a first connection (3a, 3b, 3c), and a second energy supply branch (2d) which is connected in parallel to the at least one first energy supply branch (2a, 2b, 2c) and which is designed to supply a field winding (11) of the separately excited electrical machine (1) with current via a second connection (3d), the at least one first energy supply branch (2a, 2b, 2c) and the second energy supply branch (2d) being connected to the field winding (11) by means of third connections (4a, 4b, 4c; 4d) via a common reference bus (9).
