A method for operating a battery module, including multiple battery cells. The method includes: a) ascertaining cell voltages of the individual battery cells at a starting point in time; b) ascertaining at the starting point in time an average cell voltage from the cell voltages of the battery cells ascertained at the starting point in time; c) estimating the cell voltage of at least one battery cell at an operating point in time if the cell voltage of the battery cell is not measurable at the operating point in time, taking into account the cell voltage of the battery cell ascertained at the starting point in time, the average cell voltage ascertained at the starting point in time, and an average cell voltage ascertained at the operating point in time.
