Patent ID: 10991993

Abstract:
The invention relates to a method for operating a battery having at least one battery module (2) with at least one battery cell (3), having the following method steps: a. determining a first value of at least one first monitored variable of the at least one battery module (2) and/or the at least one battery cell (3), c. checking whether the determined first value of the at least one first monitored variable lies within a specified first target range for the at least one first monitored variable, the first target range being determined in particular in a method step b, and d. replacing the at least one battery module (3) with a different battery module and/or replacing the at least one battery cell (2) with a different battery cell if the determined first value of the at least one first monitored variable lies outside of the first target range for the at least one first monitored variable, wherein the first value of the at least one first monitored variable for the other battery module or the other battery cell lies within the first target range for the at least one first monitored variable.
