The invention relates to a controllable energy store (2) with n parallel energy supply branches (3-1, 3-2, 3-3), where n>=1, each of which comprises at least two serially connected energy storage modules (4). Each energy storage module comprises at least one electric energy storage cell (5) having an associated controllable coupling unit (6). The coupling units (6) bridge the associated power storage cells (5) in accordance with control signals or connect the associated energy storage cells to the respective energy storage branch (3-1; 3-2; 3-3). At least one energy storage module (4-11; 4-21; 4-31) is designed such that it has reduced switching losses, reduced in particular by at least 10% compared to the other energy storage modules (4) in the respective power supply branch (3-1; 3-2; 3-3).
