  • Patent number: 11525865
    Abstract: An electric energy supply system having at least one cell element, which contains at least one galvanic cell, and having a measuring circuit, which is configured to ascertain at least one parameter of the at least one cell element by electrochemical impedance spectroscopy (EIS). The disclosure provides that the energy supply system comprises an electrochemical gas sensor and the gas sensor is connected to the measuring circuit via a toggle switch, wherein the measuring circuit is configured to apply an electric variable as the excitation variable in the gas sensor and to detect another electric variable as the measured variable at the gas sensor and to ascertain a gas concentration in the surroundings of the gas sensor.

  • Patent number: 11519968
    Abstract: A measurement arrangement for determining a complex impedance of a first electrical component, wherein the measurement arrangement comprises the first component and a measuring unit, which is coupled to the first component and adapted to determine the complex impedance of the first component. The measurement arrangement comprises at least one second electrical component, which is arranged with the first component in a parallel circuit, which is hooked up in parallel with the measuring unit, wherein the parallel circuit comprises at least one switching device by which an electrical connection between the first and second component can be broken, and wherein the measurement arrangement is designed to temporarily break the electrical connection between the first component and the second component by the associated switching device in order to determine the first complex impedance of the first component.

  • Publication number: 20210146791
    Abstract: A battery cell with a galvanic cell, a first semiconductor switching element, a first cell connector electrically coupled directly to a first potential connector of the galvanic cell, and a second cell connector electrically coupled to a second potential connector of the galvanic cell via the first semiconductor switching element. The battery cell further has a third cell connector electrically coupled to the second potential connector of the galvanic cell, a second semiconductor switching element, and a fourth cell connector electrically coupled to the first potential connector of the galvanic cell via the second semiconductor switching element. A third semiconductor switching element is connected between the third cell connector and the fourth cell connector which primarily serves to switch individual battery cells out of the system regardless of the (activation or deactivation) state of the predecessor as well as successor cells.

  • Publication number: 20210151727
    Abstract: A cell having a galvanic cell. The galvanic cell has a first and a second electrode connection. The first electrode connection is connected to a first cell connection and the second electrode connection is connected to a second cell connection. The battery cell has a third and a fourth cell connection and at least four semiconductor switching elements, by which the electrode connections, depending on a respective switching state of the semiconductor switching elements, can each be electrically coupled to the third or the fourth of the cell connections. These are primarily used to remove and add individual battery cells from or to the system and/or to connect cells in parallel, independently of the (activation or deactivation) state of the preceding and following cells.

  • Publication number: 20200269855
    Abstract: A method for determining at least one characteristic value of a drivetrain, which drivetrain is located in the installed state in a motor vehicle that can be partially or fully electrically driven using the drivetrain and has an electrical part having electrical components and a mechanical part having mechanical components. The electrical part and the mechanical part are coupled via an electrical machine. A predetermined mechanical boundary condition for the electrical machine is set by actuating at least one of the mechanical components of the mechanical part and/or using at least one vehicle-external mechanical component. A control device generates an electrical excitation signal in the electrical part by actuating at least one of the electrical components of the electrical part and detects a response signal using a measuring device of the motor vehicle.
