Abstract
Various embodiments include a method for determining the age of an electrochemical energy storage unit comprising: referring to a first open-circuit voltage curve of the electrochemical energy storage unit dependent upon the state of charge of the electrochemical energy storage unit as a reference; ascertaining a second open-circuit voltage curve of the electrochemical energy storage unit dependent upon the state of charge of the electrochemical energy storage unit; and determining the age of the electrochemical energy storage unit by comparing the first and second open-circuit voltage curves.
