  • Patent number: 11029364
    Abstract: In order to determine the charging capacity state and the state of health of an electrical energy store of a battery system (BS1; BS2) with little effort, a measuring device (ME) is proposed, which measuring device injects, into a drive train which is available for first or second loads (VR1; VR2) and has an AC/DC converter (ADC) or a DC/DC controller (DDC) on the DC side of the AC/DC converter (ADC) or of the DC/DC controller (DDC), a sinusoidal voltage harmonic with a varied frequency or a sinusoidal current with a varied frequency as a particular measurement signal which is transmitted to the battery system (BS1; BS2). The current response or voltage response, which has been purged of unwanted influences, is then determined for each measurement signal at the battery system (BS1; BS2), from which response phase shifts are determined in each case, and parameters for a statement relating to the charging capacity state or the state of health of the battery system (BS1; BS2) are in turn determined therefrom.
