Abstract

The invention relates to a method for charging an electrical energy store, the electrical energy store comprising at least one electrical energy storage unit and a predefined maximum permissible energy-store voltage limit value being specified for the electrical energy store. The electrical energy store is charged with a pulsed charging voltage, a maximum value of the pulsed charging voltage being greater than the predefined maximum permissible energy-store voltage limit value over a pulse duration in the case of at least one pulse. The invention further relates to a corresponding device for charging the electrical energy store, to a corresponding computer program, to a corresponding machine-readable storage medium and to a corresponding electrical energy store.
