Abstract: A method and to a device for charging a battery for a means of transport. The method comprises the steps of: ascertaining an open-circuit voltage of the battery (30) on the basis of a voltage ramp that is generated by a controllable DC-to-DC converter (40) that is electrically connected to the battery (30), ascertaining a differential internal resistance of the battery (30) on the basis of a predefined model for the differential internal resistance of the battery (30) and the open-circuit voltage, ascertaining a target value for an output voltage of the DC-to-DC converter (40) on the basis of the open-circuit voltage of the battery (30), a predefined charging current of the battery (30) and the differential internal resistance of the battery (30), and charging the battery (30) using the target value for the output voltage in the DC-to-DC converter (40).

Abstract: The invention relates to a method (400) for regulating the power of an electric consumer (120_1) in an electric system (100) having an electric energy source (160) and at least one first electric consumer (120_1). The energy source (160) has a state of charge. The power demand of the first electric consumer (120_1) in a future time segment is determined (410). The power of the first consumer (120_1) is regulated (420) in the future time segment as a function of the state of charge and of the determined power demand.
