The disclosure relates to a method for balancing out states of charge of a battery which has a number of N battery cells. In order to balance out the individual states of charge (SOCn) of the n=1 to N cells, the state of charge of at least one cell is changed to a target state of charge (SOCtarget,n) which depends on the discharge depth (DODk) of the cell having the lowest capacity (Capk) according to the equation SOCtarget,n=1−DODk/Capn, Capn being the capacity of the nth cell to be changed. Advantageously, the method is suitable for optimizing the voltage or the energy content of a battery that is constituted of a plurality of cells.
