Abstract

A method for operating a hybrid vehicle having an electrical energy store, an electric drive and an internal combustion engine, includes activating, by a driver of the hybrid vehicle, a battery control mode by actuating a defined operator control element. A special drive operating strategy for the internal combustion engine is triggered in the battery control mode with the electric drive switched off. An increased charging gradient is then obtained by the special drive operating strategy if a current state of charge of the electrical energy store is below one of a desired state of charge or a lower tolerance threshold with respect to the desired state of charge.
