A method for determining a constant current limit value by means of which a first current which flows through a battery cell is limited, wherein the constant current limit value is determined on the basis of a first function which specifies a first profile of the first current, which first profile is dependent on a plurality of parameters. The plurality of parameters include a first voltage which is applied between two terminals of the battery cell, a second voltage which specifies a no-load voltage of the battery cell, and a time variable.
