METHOD AND DEVICE FOR THE OPEN-LOOP AND/OR CLOSED-LOOP CONTROL AT LEAST OF ONE OPERATING PARAMETER OF AN ELECTRICAL STORAGE DEVICE, WHEREIN SAID OPERATING PARAMETER INFLUENCES A STATE OF AGING OF AN ELECTRICAL ENERGY STORAGE DEVICE
First Claim
1. A method for at least one of open-loop and closed-loop control of at least one operating parameter of an electrical energy storage device of a motor vehicle, wherein the at least one operating parameter influences a state of aging of the electrical energy storage device, said method comprising the following steps:
- determining an actual state of health (SOHactual) of the electrical energy storage device;
determining a desired state of health (SOHdesired) of the electrical energy storage device; and
adjusting an operating parameter range that is permissible for the at least one operating parameter if a comparison of the actual state of health (SOHactual) with the desired state of health (SOHdesired) indicates that the actual state of health demonstrates at least one of an increased rate of aging and a reduced rate of aging in comparison to the desired state of health (SOHdesired), wherein the operating parameter range is adjusted so that the electrical energy storage device is operated within the adjusted operating parameter range at least one of;
at a reduced rate of aging if the comparison indicates that the actual state of health demonstrates an increased rate of aging, and at an increased rate of aging if the comparison indicates that the actual state of health demonstrates a reduced rate of aging.

Abstract
A method and a device for the open-loop and/or closed-loop control of at least one operating parameter of an energy storage device, the operating parameter influencing a state of aging of the energy storage device, to prevent too great a deviation from a planned serviceable life of the energy storage device. The method includes determining an actual state of health and a desired state of health of the energy storage device, and adjusting an operating parameter range that is permissible for the at least one operating parameter range if a comparison of the actual state of health with the desired state of health demonstrates an increased rate or reduced rate of aging in comparison to the desired state of health, wherein the operating parameter range is adjusted so that the energy storage device is operated at a reduced or an increased rate of aging, respectively.
