A method is provided for the open-loop or closed-loop control of at least one operating parameter of an electric energy accumulator influencing the aging state of the electric energy accumulator. The method determines the actual aging state of the electric energy accumulator, compares the actual aging state with a target aging state predefined for the momentary age of the energy accumulator, and restricts an operating parameter range permitted for the at least one operating parameter if the actual aging state is worse than the target aging state.

Method for controlling at least one operating parameter that influences the aging state of an electrical energy store in an open-loop or closed-loop manner

A method for operating an electric high voltage energy storage device of a hybrid vehicle with an electric drive motor, as well as an energy supply device, is provided. A predetermined working range of the high voltage energy storage device is shifted in the direction of the upper or lower physical charge limit as a function of the vehicle operating parameters and/or as a function of the vehicle environmental parameters.
