Receiving structure for battery cells and method for producing a receiving structure for battery cells
The present disclosure sets out a receiving structure for battery cells and, in particular for a high-voltage battery for a motor vehicle, the structure including a cell holder made of a foam material with recesses for receiving and fixing the respective battery cells, the cell holder being shaped in such a way that, when the battery cells are arranged in the recesses as intended, at least one region is left free at the respective battery cells, so that an electrically non-conductive cooling medium can flow around this region. The disclosure further sets out a battery and in particular a high-voltage battery for a motor vehicle, having at least one such receiving structure as well as to a method for producing a receiving structure for battery cells.
1 . A receiving structure for at least one of battery cells and a high-voltage battery for a motor vehicle, the receiving structure comprising:
a cell holder comprising closed-cell, rigid, self-extinguishing foam material withrecesses configured for receiving and fixing the battery cells, and
wherein the cell holder is configured such that, when the battery cells are arranged in the recesses, at least one region is recessed at the respective battery cells, so that an electrically non-conductive cooling medium can flow around the recessed region of the respective battery cells without penetrating the foam material.
2 . The receiving structure according to claim 1 wherein the closed-cell foam material is rigid foam material.
3 . The receiving structure according to claim 1 , wherein:
the recesses are cylindrical and are configured to radially fix the battery cells;
the battery cells are configured as round cells; and
at least respective end faces of the round cells are exposed when the round cells are arranged in the recesses.
4 . The receiving structure according to claim 1 , wherein the receiving structure comprises a cell frame, and wherein the cell holder is arranged at least partially within the cell frame.
5 . The receiving structure according to claim 4 , wherein the cell frame comprises two frame halves and the cell holder is arranged at least partially in a receiving space enclosed by the frame halves.
6 . The receiving structure according to claim 4 wherein the cell frame is configured to be liquid-tight and the cell holder is arranged inside the cell frame comprising connections for supplying and discharging the electrically non-conductive cooling medium.
