Claim 0:
1. A device for operating an electrical energy store for supplying power to components of an electrically operable motor vehicle, wherein operational limits are defined in each case for one or more characteristic variables of the energy store, wherein exceeding of the operational limits is prevented, during normal operation of the energy store, by a control unit, comprising:
an interface for receiving, from an appliance, a user-side request message which contains modification information relating to an intended shift in an operational limit of at least one of the characteristic variables;
an arithmetic logic unit, which is designed to check, on reception of the request message, the intended shift in the operational limit of at least one of the characteristic variables depending on at least one operation history which is stored for the energy store and represents information derived from one or more of the characteristic variables of the energy store and relating to past operating conditions of the energy store, and to permit said intended shift when at least one of the following conditions has been met:
(i) information, which is established from the at least one operation history and represents the present state of health, meets a preset criterion;
(ii) a monetary transaction initiated by the arithmetic logic unit depending on the present state of health has been concluded.
