Abstract
A method for determining the wear to an electrochemical energy store includes determining the temperature of a battery and determining a wear variable over time as a function of the battery temperature. The wear variable is determined as a sum of temperature-dependent wear contributions over time, with the values of the wear contributions rising more than proportionally as the battery temperature rises. An energy store such as a battery or a system provided with an energy store includes a temperature measurement device or means and a computation device or means configured to calculate a wear variable in accordance with the method.
