For controlling the charge state of a battery in a hybrid vehicle having an internal-combustion engine and an electric machine, the battery is operated in a working state-of-charge range falling within a theoretically possible state-of-charge range. In a first sub-range, the battery is charged by the electric machine, the electric machine working as a generator and being engine driven. In a second sub-range, the battery is neither charged nor discharged, the electric machine working as a generator and being driven by the engine and, in the process, supplying only an on-board power supply system of the hybrid vehicle with current. In a third sub-range, the battery is discharged and, in the process, supplies the on-board power supply system with current, the electric machine running along passively. In a fourth sub-range, the battery is discharged and, in the process, supplies current to the electric machine operating as an electric motor.
