  • Publication number: 20220176872
    Abstract: A method is provided for monitoring an image refresh frequency of HD headlights for a vehicle. The HD headlight has a control unit that causes a display with light point sources to generate light images in continued temporal succession for a predefined time duration. An image refresh frequency corresponding to the inverse of the predefined time duration is updated by a next light image. A video signal composed of image information items and signal information items is provided to the control unit by a video interface that impresses the temporally changing information item on the signal information items of the video signal. The control unit checks the signal information items of the video signal with respect to the temporally changing information item to assess correspondence with the temporal succession available to the HD headlight and a substitute reaction of the HD headlight is initiated in the event of erroneous correspondence.

  • Publication number: 20210328272
    Abstract: A battery cell. The battery cell incluedes a first terminal contact and a second terminal contact, an energy storage unit, a first transistor, a sensor system that is set up to acquire a state parameter of the battery cell, and a control circuit. A first pole of the energy storage unit is coupled to the first terminal contact, and a second pole of the energy storage unit is coupled to the second terminal contact. The first transistor is connected between the first terminal contact and the second terminal contact in series with the energy storage unit. The he control circuit is set up to control a switching process of the first transistor, the control circuit controlling the first transistor based on the acquired state parameter in order to control a charge current or a discharge current of the energy storage unit.

  • Publication number: 20210309115
    Abstract: A method for operating at least one electrical component of a vehicle with the aid of a battery. At least two battery cells of the battery are electrically connected and thus added to the at least one component via at least one particular switching unit. The following steps for precharging a DC link of the vehicle is carried out: a) adding a first of the battery cells, b) incrementally adding at least a second of the battery cells, after a previous adding has taken place in each case.

  • Publication number: 20210167473
    Abstract: A method for disconnecting a battery including at least two battery cells from at least one electrical component of a vehicle. At least two switching units are associated with each of the battery cells, the battery cells each being electrically connected to the component as a function of the at least two switching units in each case, so that a power supply is established for the component by the battery. The following steps are carried out for the disconnection from the component: a) switching the at least two switching units of a first battery cell of the battery cells, b) switching the at least two switching units of at least a second battery cell of the battery cells.
