Patent ID: 11958366

Abstract:
A device operates an electrical energy store for supplying components of an electrically operable motor vehicle, wherein operating limits are defined in each case for one or more characteristic variables of the energy store. A control unit prevents the operating limits from being exceeded during normal operation of the energy store. The device has an interface for receiving a user-side request message from an apparatus, the request message including change information about an intended shift in the operating limit of at least one of the characteristic variables. The device has a computing unit which is designed, upon receipt of the request message, to check and permit the shifting of the operating limit of at least one of the characteristic variables in accordance with at least one operational history which is stored for the energy store and which represents information derived from one or more of the characteristic variables of the energy store about past operating conditions of the energy store if at least one of the following conditions is satisfied: information determined from the at least one operational history and representing the current state of health satisfies a predetermined criterion; and/or a monetary transaction initiated by the computing unit in accordance with the current state of health has been completed.
