Electrochemical energy store and method for determining the wear to an electrochemical energy store
First Claim
Patent Images
1. A method for determining the wear to an electrochemical energy store, comprising:
- continuously determining the amounts of charge (qL) converted during charging cycles of the energy store; and
calculating a wear variable (Qv) which characterizes the wear as a function of the determined converted amount of charge (qL);
wherein the determined converted amount of charge (qL) is greater than a defined minimum amount of charge (qmin) per charging cycle; and
wherein the minimum amount of charge (qmin) is in the range from 0.1 to 1×
10−
6 times an initial capacity (Qn) of an equivalent new energy store.
