  • Patent number: 10297882
    Abstract: A battery system includes a plurality of battery cells and a temperature-control element that is thermally conductively connected to the battery cells via a temperature-control surface. The temperature-control element has a temperature-control channel in an interior of the temperature-control element. The temperature-control channel is routed on the forward flow side via an inlet and on the return flow side via an outlet from the temperature-control element. A bypass is connected to the temperature-control channel via a dividing node and a merging node with the dividing node being arranged closer to the inlet than the merging node. A motor vehicle includes the battery system.

  • Patent number: 9985324
    Abstract: A device for the temperature control of battery cells in a battery, particularly a battery configured as an energy source for the drive of hybrid, plug-in hybrid, or electric vehicles includes a contact surface for thermally contacting the battery cells with the device. The contact surface is configured such that the battery cells to be temperature-controlled are arranged on the contact surface. The device has elements below the contact surface that are elastically restoring such that, when a compressive load acting orthogonally to the contact surface is applied, the contact surface is lowered in the region of the applied compressive load. A restoring force acts against the compressive load.
