A method for the open-loop and/or closed-loop control of at least one operating parameter of an electrical energy store of a motor vehicle, which operating parameter influences a state of health of the electrical energy store, said method comprising the following steps: a) determining an actual state of health (SOH Actual) of the electrical energy store; b) determining a desired state of health (SOH Desired) of the electrical energy store; and c1) adjusting an operating parameter range that is permitted for the at least one operating parameter if a comparison of the actual state of health (SOH Actual) with the desired state of health (SOH Desired) reveals that the actual state of health shows increased ageing in comparison to the desired state of health (SOH Desired), wherein the operating parameter range is adjusted so that the electrical energy store is operated at a reduced rate of ageing within the adjusted operating parameter range; and c2) adjusting the operating parameter range that is permitted for the at least one operating parameter if a comparison of the actual state of health (SOH Actual) with the desired state of health (SOH Desired) reveals that the actual state of health shows reduced ageing in comparison to the desired state of health (SOH Desired), wherein the operating parameter range is adjusted so that the electrical energy store is operated at an increased rate of ageing within the adjusted operating parameter range; characterized by d) determining a remaining service life or remaining mission distance of the electrical energy store until said electrical energy store is expected to reach an "end-of-life" state of health, wherein the operating parameter range that is permitted for the at least one operating parameter is adjusted on the basis of the determined remaining service life or remaining mission distance such that the adjustment is greater as the remaining service life or remaining mission distance decreases. a) determining an actual state of health (SOH Actual) of the electrical energy store; b) determining a desired state of health (SOH Desired) of the electrical energy store; and c1) adjusting an operating parameter range that is permitted for the at least one operating parameter if a comparison of the actual state of health (SOH Actual) with the desired state of health (SOH Desired) reveals that the actual state of health shows increased ageing in comparison to the desired state of health (SOH Desired), wherein the operating parameter range is adjusted so that the electrical energy store is operated at a reduced rate of ageing within the adjusted operating parameter range; and c2) adjusting the operating parameter range that is permitted for the at least one operating parameter if a comparison of the actual state of health (SOH Actual) with the desired state of health (SOH Desired) reveals that the actual state of health shows reduced ageing in comparison to the desired state of health (SOH Desired), wherein the operating parameter range is adjusted so that the electrical energy store is operated at an increased rate of ageing within the adjusted operating parameter range; characterized by d) determining a remaining service life or remaining mission distance of the electrical energy store until said electrical energy store is expected to reach an "end-of-life" state of health, wherein the operating parameter range that is permitted for the at least one operating parameter is adjusted on the basis of the determined remaining service life or remaining mission distance such that the adjustment is greater as the remaining service life or remaining mission distance decreases.
