A method for ascertaining at least one performance characteristic for the operation of an electrical energy store is described, comprising the steps of: a) receiving operating data, in particular current and/or voltage and/or temperature measured values, of a multiplicity of electrical energy stores, wherein the multiplicity of electrical energy stores satisfy a predefined criterion, for example a predefined number of operating hours; b) ascertaining at least one ageing state variable, in particular an electrical capacitance, of the multiplicity of electrical energy stores by evaluating the operating data of the multiplicity of electrical energy stores; c) ascertaining at least one performance characteristic for the operation of an electrical energy store, in particular a maximum charging current, on the basis of the at least one ageing state variable; d) transmitting the at least one performance characteristic to a further multiplicity of electrical energy stores. Furthermore, a corresponding computer program, a corresponding machine-readable storage medium and a corresponding computer apparatus are described.
