Abstract
Methods are described for determining the state of charge and/or the operability of a charge accumulator using estimates. The information, which is obtained at a least two different operating points or operating conditions of the energy accumulator, is taken into account in the estimates. The estimates are carried out with regard to an instantaneous and/or future state of charge and/or an instantaneous and/or future operability of the charge accumulator. Different methods are executed, depending on the operating point or operating condition. The methods may be run in a processor of a control unit.
