An onboard electrical system is disclosed that includes first, second and third onboard electrical sub-systems for an electric drive unit, electric components and a vehicle battery of a vehicle, respectively. In addition, the system includes a charging terminal, wherein a changeover switch, a first switch element, and a second switch element of the onboard electrical system are physically separated from one another. The charging terminal is galvanically connected to the third onboard electrical sub-system by the first switch element and to the second onboard electrical sub-system by the changeover switch during an electric charging mode of the vehicle battery. The first onboard electrical sub-system is galvanically connected to the third onboard electrical sub-system of the second switch element and to the second onboard electrical sub-system by the changeover switch during a driving mode of the vehicle.

A motor vehicle shell of a motor vehicle includes a frame structure that is formed by crossmembers and by longitudinal members. The frame structure is closed peripherally and protrudes downwardly in a vertical direction of the motor vehicle from a base element. A receiving chamber for receiving an electrical energy store is delimited by the frame structure. A cover is formed separately from the frame structure and is disposed opposite the base element. The receiving chamber is closed downwardly in the vertical direction of the motor vehicle by the cover. An annular and dimensionally stable intermediary element is formed separately from the frame structure and separately from the cover. The intermediary element is disposed between the frame structure and the cover and the intermediary element is fixed at least in a liquid-tight manner on the frame structure by a firmly bonded connection.

A method for determining a cell voltage of a battery cell of a traction battery of a vehicle includes filtering the cell voltage of the battery cell by a filtering device, sampling the filtered cell voltage by an analogue to digital converter, transferring the filtered and sampled cell voltage as a cell voltage signal to a computing device, evaluating the cell voltage signal by the computing device, determining a ripple value which describes a ripple of the cell voltage, and evaluating the cell voltage signal depending on the ripple value.
