A method for balancing state of charge of a battery

The invention relates to a method for balancing state of charge of a battery having a plurality of battery units (2-1, 2-2). It is provided that a state of charge value of at least one battery unit is determined whether a previous state of charge value of the at least one battery unit (2-1, 2-2) can be updated, it is determined (2-2 2-1), a decision value, which previous state of charge value of the at least one battery unit (2-1, 2-2) is updated to obtain a current state of charge value of the at least one battery unit (2-1, 2-2) in case the decision value, whether the previous state of charge value of the at least one battery unit ( , 2-2) may be 2-1 to be updated exceeds a threshold value, a charge state compensation demand value based on the current state of charge value is determined and the at least one battery unit (2-1, 2-2) is discharged on the basis of the charge state compensation demand value determined. a computer program and a battery management system, there are also indicated, which are adapted for performing the method, and a battery and a motor vehicle, the drive system is connected to such a battery.
