  • Publication number: 20240097257
    Abstract: Battery device for an at least semi-electrically powered motor vehicle includes a battery housing and an assembly of battery cells and compression pads arranged between the battery cells. The compression pads are elastically configured in order to be able to exert a surface compression on the battery cells and to compensate for volume changes of the battery cells. The compression pads each include at least one swelling body, which is suitable and configured to expand from an unswollen pre-mounting state to a swollen finished mounting state by absorbing an activator fluid, thereby increasing its volume such that the compression pads can exert their intended surface compression on the battery cells.

  • Patent number: 11728524
    Abstract: A battery arrangement (10) for an electrically drivable motor vehicle has a battery housing (12) for receiving battery cells for electrically driving the motor vehicle. A control electronics system (14) is provided outside the battery housing (12) for controlling the battery cells. A module housing (16) is connected to the battery housing (12) for covering the control electronics system (14) and a module heat-conducting element (28) is provided between the control electronics system (14) and the module housing (16) so that heat generated in the control electronics system (14) is dissipated to the module housing (16) by heat conduction. The module housing (16) and the module heat element (28) passively cool the control electronics system (14), which is provided outside the battery housing (12), thereby providing simple and cost-effective dissipation of heat produced in the battery arrangement (10).
