Abstract
A method for determining the wear to an electrochemical energy store and an electrochemical energy store allows for continuously determining the amounts of charge (q.sub.L) converted during charging cycles of the energy store and calculating a wear variable (Q.sub.v) which characterizes the wear as a function of the determined converted amount of charge (q.sub.L).
