  • Publication number: 20240339651
    Abstract: A cell separation element for arrangement in an intermediate space between two battery cells. The cell separation element is designed to be at least partially elastically compressible with respect to a first direction. The cell separation element has a first corrugated structural wall with a corrugated structure. When the cell separation element is arranged as intended in the intermediate space, a first side surface of the corrugated structural wall faces a first of the two battery cells and a second side surface of the corrugated structural wall faces a second of the two battery cells. The structural wall is designed to provide a restoring force when the cell separation element is compressed with respect to the first direction.

  • Patent number: 11824222
    Abstract: A high-voltage battery for an electrically operated vehicle, the battery housing of which has a housing cover and a housing lower part which delimit a housing interior which is divided into at least one battery cell compartment equipped with battery cells and at least one component compartment for electronic components. A degassing space is formed between a battery cell top of the battery cells and the housing cover, into which space hot exhaust gas flows during a thermal event in one of the battery cells from an exhaust gas outlet of the damaged battery cell. The high-voltage battery has a partition wall which separates the degassing space from the component compartment.

  • Publication number: 20230112971
    Abstract: A cooling arrangement for cooling a cell assembly having multiple cell units of a motor vehicle battery. The cooling arrangement has multiple cooling units, and a respective one of the cooling units is associated with one of the cell units. The cooling arrangement includes a control device adapted to separately control a cooling capacity for a respective one of the cooling units. In this case, the control device is designed to control the cooling units differently in a specific first cooling mode than in a specific second cooling mode different from the first. The cooling arrangement is configured in such a way that, in the event of a fault case affecting a first cell unit of the multiple cell units, a switch is performed from the first cooling mode to the second cooling mode.
