Abstract: The present invention relates to a method for determining a proportion of defective battery cells in a group of battery cells connected electrically in parallel in a battery, where a voltage state of a terminal voltage of the group is determined in relation to a charging process and/or in relation to a relaxation of the battery under an environmental condition and a deviation of the determined voltage state of the terminal voltage from the voltage state of the terminal voltage of the same group from a previous charging process and/or a previous relaxation under the same environmental condition is calculated, where the proportion of defective battery cells in the group is determined from the calculated deviation.
