1. A method for parameterizing an electrochemical battery model of a specific battery of a device, comprising:
providing a current operating feature point of the specific battery and operating feature points of further batteries of a plurality of further devices for various evaluation periods, wherein the operating feature points of the further batteries characterize an operation of a respective further battery within one or more of the evaluation periods based on several operating features, wherein the several operating features are produced depending on characteristics of operating variables of the respective further battery;
selecting operating feature points of the further batteries that are similar to the current operating feature point of the specific battery;
providing model parameters of the electrochemical battery model that are associated with the current operating feature point and the selected operating feature points;
ascertaining at least one fused model parameter depending on the model parameters of the current operating feature point of the specific battery and the selected operating feature points of the further batteries; and
signaling the at least one fused model parameter or updating the electrochemical battery model using the at least one fused model parameter.
