  • 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: 20210288358
    Abstract: A circuit system for a rechargeable battery system. The circuit system includes at least one actuator that is assigned to an individual cell of the battery system in order to switch a discharge of the cell. At least one sensor system that is assigned to the individual cell in order to monitor the cell and in order to control the actuator, as a function of the monitoring, to bring about a discharge in the case of an error state.

  • 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.

  • Patent number: 10770564
    Abstract: A MOS component includes a source area, a drain area, a body area, a channel area, and a gate element, the channel area and the gate element being electrically insulated with respect to one another by a total of at least three individual layers in the form of a first individual layer, a second individual layer, and a third individual layer. The second individual layer is designed in such a way that it may permanently store electric charges. The third individual layer, which is situated between the channel area and the second individual layer, has a greater equivalent oxide thickness than the first individual layer situated between the second individual layer and the gate element.

  • Patent number: 10505489
    Abstract: A power module for an electric motor includes at least one semiconductor switch half bridge. The half bridge includes a high-side semiconductor switch and a low-side semiconductor switch. Each switch has a contact gap terminal formed by a surface region of the switch, in particular a flat surface region. The contact gap terminals, in particular a normal vector of the terminals, each points in a same direction. At least one electrically conductive layer is enclosed between the switches and electrically connects the contact gap terminal of the low-side semiconductor switch and the contact gap terminal of the high-side semiconductor switch of the half bridge to each other. Preferably an output terminal of the half bridge is formed by at least one electrically conductive layer.
