Patent number: 9985324Abstract: 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.Type: GrantFiled: January 16, 2014Date of Patent: May 29, 2018Assignees: Robert Bosch GmbH, Samsung SDI Co., Ltd.Inventors: Christian Loew, Achim Schmidt
