The invention relates to a method for equalising state of charge in a battery that has a plurality of battery units (2-1, 2-2). This involves provision for a state of charge value for at least one battery unit (2-1, 2-2) to be ascertained, a decision value concerning whether a prior state of charge value for the at least one battery unit (2-1, 2-2) can be updated to be ascertained, the prior state of charge value for the at least one battery unit (2-1, 2-2) to be updated in order to obtain a present state of charge value for the at least one battery unit (2-1, 2-2) if the decision value concerning whether the prior state of charge value for the at least one battery unit (2-1, 2-2) can be updated exceeds a threshold value, a state of charge equalisation requirement value to be ascertained on the basis of the present state of charge value and the at least one battery unit (2-1, 2-2) to be discharged on the basis of the ascertained state of charge equalisation requirement value. In addition, a computer program and a battery management system are specified which are designed for implementing the method, as well as a battery and a motor vehicle having a drive system which is connected to such a battery. |
