Abstract

A method for connecting battery cells in a battery is provided, the battery including at least one measuring battery cell and at least one standard battery cell in a series connection, the standard battery cell having at least a nominal capacity which is greater than a nominal capacity threshold, the measuring battery cell having a nominal capacity which is less than the nominal capacity threshold, the measuring battery cell having a switchable bypass, the method including: monitoring a state of charge of the at least one measuring battery cell; and bypassing the at least one measuring battery cell using the switchable bypass if the state of charge of the at least one measuring battery cell drops below a predefined state of charge threshold.
